The Taxation of Cryptocurrency Staking in Poland

A comprehensive legal analysis of native ETH Proof-of-Stake mechanisms, stETH and wstETH tokens – the state of judicial authority, the Director of KIS interpretive practice, the constitutional dimension, and practical guidance for Polish taxpayers

Abstract. The entry into force of Council Directive (EU) 2023/2226 (DAC8) on 1 January 2026 has transformed the question of staking income taxation in Poland from an academic curiosity into an urgent compliance challenge for tens of thousands of taxpayers. This article synthesises the current state of law, administrative court jurisprudence, and the interpretive practice of the Director of the National Tax Information Service (hereinafter “KIS”) as they bear upon three principal staking configurations: native Ethereum Proof-of-Stake validator staking, the Lido Finance stETH rebasing token, and the Lido Finance wstETH wrapped position – whose value accretes through exchange-rate appreciation rather than through any wallet event. The article identifies and analyses five independent legal grounds for the proposition that no taxable income event arises at the moment of reward accrual, and that the income event is deferred in all three configurations to the moment of disposal of virtual currency within the meaning of Article 17(1f) of the Personal Income Tax Act. The analysis surveys the leading decisions of the Cracow, Warsaw, and Wrocław Administrative Courts, the foundational ruling of the Supreme Administrative Court, and the Director of KIS’s own settled interpretive practice. The article concludes with a scenario-by-scenario tax matrix and practical recommendations for taxpayers engaged in staking activity.

 

What Staking Is – and Why It Has Caught the Tax Authority’s Eye

Before we turn to the legal analysis, the phenomenon itself deserves a careful introduction – because it is precisely the legislature’s and the tax authority’s incomplete understanding of its mechanics that lies at the root of the problems this article examines.

A network that needs guardians

Cryptocurrencies – Bitcoin and Ethereum foremost among them – are digital financial systems that operate without a central administrator. There is no central bank, no clearing house, no institution that decides which transactions are valid and which are not. That function is performed by the network itself: thousands of computers distributed across the globe, which collectively verify every transaction and record it in a public, immutable ledger known as a blockchain.

The challenge is that such a system requires a mechanism to prevent fraud. Since there is no central arbiter, a malicious actor could attempt to spend the same funds twice or falsify the transaction history. Bitcoin solves this problem through Proof of Work – complex mathematical computations performed by specialised hardware that “mines” new blocks of transactions at enormous energy cost. Ethereum – the second-largest cryptocurrency network – employed the same mechanism until September 2022, when it underwent a fundamental transformation.

 

Proof of Stake: security through capital, not energy

In September 2022, Ethereum transitioned to a Proof of Stake model, in which network security is guaranteed not by computational power but by capital deposited by participants. The mechanism is elegantly simple: anyone who wishes to participate in transaction validation – that is, in confirming that transactions are legitimate and appending them to the blockchain – must deposit 32 ETH, equivalent at the date of publication to approximately EUR 55,000–65,000, as a stake. The deposited funds serve as a bond: if the validator behaves honestly and verifies transactions correctly, it receives a reward; if it attempts to cheat or is negligent, it loses part of its deposit (a mechanism known as slashing).

It is this deposit – and the rewards it generates – that forms the subject matter of the present analysis. Staking is, in essence, the deposit of cryptocurrency for the purpose of securing a blockchain network in exchange for periodic rewards paid in the same cryptocurrency.

 

Three forms of staking – from simple to sophisticated

In practice, staking takes three fundamentally distinct forms, each of which raises separate tax questions.

Native staking (solo staking) is the simplest form: the taxpayer independently operates validator software, deposits 32 ETH, and participates in the transaction verification process. Rewards are credited directly to the taxpayer’s Ethereum address – partly automatically (approximately every four to five days), partly in the form of transaction fees collected from network users. The current annualised yield is approximately 2.0–3.5%.

Liquid staking – the Lido stETH model. The 32 ETH threshold and the need to maintain technical infrastructure present a barrier for most investors. The solution is Lido Finance – a protocol that aggregates deposits from multiple users and distributes rewards proportionally. In exchange for deposited ETH, the user receives a token called stETH (staked ETH), whose wallet balance increases daily by the user’s proportionate share of staking rewards. The balance increase occurs automatically, without any transaction by the user – it is merely a change to a state variable in the Lido protocol’s smart contract. As of the date of publication, Lido controls approximately 24% of all staked ETH, making it the largest single staking operator in the world.

Wrapped liquid staking – the Lido wstETH model. A variant of stETH is the wstETH (wrapped staked ETH) token, whose nominal balance never changes. Instead, the exchange rate of wstETH to stETH rises over time – as of the date of publication, it stands at approximately 1.23 stETH per wstETH and increases with each passing day. wstETH thus behaves like a zero-coupon bond: it pays no interest, but its market value rises as rewards accumulate. The distinction – between a rising balance (stETH) and a rising exchange rate (wstETH) – proves critical to the tax analysis, because in the case of wstETH, no event whatsoever is visible in the user’s wallet.

 

Why this is a tax problem?

The problem is deceptively simple: do staking rewards – appearing in the taxpayer’s wallet without active intervention, denominated in cryptocurrency rather than in local currency – constitute taxable income at the moment they are received, or only at the moment they are converted to fiat money? The difference is fundamental: in the first scenario, the taxpayer would be required to value and declare each daily accrual of rewards (raising the question: at what exchange rate? from which day? at what hour?); in the second, taxation arises only upon sale, under clear statutory rules.

As we shall demonstrate in the analysis that follows, the Polish administrative courts have endorsed the second scenario – but their reasoning, while legally correct, rests on a simplified picture of reality. Sophisticated strategies combining staking with DeFi lending protocols create situations in which the taxpayer effectively monetises staking rewards without any event qualifying as a disposal. The tension between the letter of the law and economic substance is the central subject of this article.

 

The Regulatory Context: Why the Question Is Urgent

For much of the period since the Ethereum Merge, the tax treatment of staking rewards in Poland occupied an uneasy middle ground between contested administrative practice and an emerging, taxpayer-friendly judicial line. Taxpayers operated without binding guidance; the Director of KIS issued rulings of questionable coherence; and the administrative courts began, with increasing confidence, to annul those rulings. That period of productive ambiguity has come to an end.

The entry into force of Council Directive (EU) 2023/2226 – DAC8 – on 1 January 2026 marks a structural inflection point. DAC8 imposes upon crypto-asset service providers (CASPs) regulated within the European Union an obligation to report user account and transaction data directly to the competent tax authorities of each relevant member state. The reporting regime is aligned with the OECD Crypto-Asset Reporting Framework (CARF) and, in its current iteration, covers centralised exchanges and custodial service providers; subsequent revisions to encompass material DeFi protocols above defined thresholds are under active consideration at the OECD level. A qualification is warranted: in its present form, DAC8 mandates the reporting primarily of transaction-level data – crypto-to-fiat exchanges, crypto-to-crypto exchanges, and transfers – rather than accrual-side income events. The reporting of staking income as a discrete income category is not currently obligatory under the directive text, though it may be implemented at the national level. However, platforms offering staking services must register and report as CASPs under DAC8, creating a data trail that tax authorities can cross-reference against filed returns – even where accrual-level data is not automatically transmitted in the first exchange cycle. The practical exposure for Polish taxpayers is accordingly concentrated at the fiat exit point (which is unambiguously reportable) rather than at the reward accrual point, but the evidentiary infrastructure is being assembled.

The scale of the affected population is not trivial. Global Ethereum staking crossed the threshold of thirty percent of total circulating supply in early 2026, with the aggregate value of staked assets on the Ethereum mainnet approaching one hundred billion United States dollars. The Polish cohort of taxpayers actively engaged in staking – while not precisely quantified – is estimated by practitioners at several tens of thousands of individuals. With annualised staking yields of two to four point two percent in 2026 conditions, and with ETH price variability introducing further complexity, the aggregate tax exposure at stake across the affected population is substantial.

The consequence for any individual taxpayer is straightforward but consequential. The difference between the legally correct interpretation – income arises exclusively upon disposal – and the adverse interpretation advanced by the Director of KIS in its pre-litigation rulings – income arises upon every reward accrual or rebase event – is, in many cases, the difference between a manageable annual tax liability and an unworkable one. The adverse interpretation would require a taxpayer to recognise income and calculate a zloty equivalent at every consensus-layer sweep, every daily stETH rebase, and potentially every incremental movement in the wstETH exchange rate – in the complete absence of a statutory methodology for making those calculations. The administrative courts have recognised this consequence as constitutionally untenable. The purpose of this article is to explain why they are correct, and what taxpayers should do about it.

 

Technical Architecture: The Three Staking Configurations

A legally rigorous analysis of the taxation of staking rewards demands, as its starting point, a precise understanding of the technical mechanisms involved. Errors in legal analysis frequently flow from an imprecise grasp of the underlying facts – in particular, from a failure to distinguish on-chain transactions initiated by the user from protocol-automated state changes that produce no blockchain transaction whatsoever. The three configurations relevant to this analysis are technically distinct in ways that carry independent legal significance.

 

2.1 Native ETH Validator Staking

Native Ethereum validation requires a minimum deposit of precisely 32 ETH into the Beacon Chain deposit contract. The depositing party – the validator – participates in the network’s consensus mechanism by submitting cryptographically signed attestations at approximately 6.4-minute intervals (epochs) and, when selected by the protocol’s pseudo-random selection algorithm (RANDAO), by proposing new blocks. Rewards flow from two architecturally distinct sources that must, for legal purposes, be considered separately.

Consensus-layer (CL) rewards are protocol-issued ETH credited to the validator’s balance on the Beacon Chain in recognition of attestation duties and sync committee participation. These rewards accumulate on the Beacon Chain. When a validator’s effective balance exceeds 32 ETH, the excess is swept automatically to the designated withdrawal address in a process known as skimming. Critically, no action is required of the validator to trigger this transfer: it is initiated by the protocol. The sweep cycle under typical network conditions runs approximately every four to five days, not continuously – a technical detail that is legally inconsequential but may be raised in cross-examination.

Execution-layer (EL) rewards – consisting of priority fees and Maximal Extractable Value (MEV) payments – are credited directly to the fee-recipient address on the execution layer at the time of each block proposal. Unlike CL rewards, they are immediately available in the fee-recipient wallet without queue or delay.

Both reward streams are denominated and delivered in ETH – a virtual currency within the meaning of Article 5a(33a) of the PIT Act read with Article 2(2)(26) of the Anti-Money Laundering and Counter-Terrorism Financing Act. Neither stream involves the delivery of Polish zloty, any other legal tender, or any asset convertible to legal tender through a mechanism prescribed by statute. The annualised yield from native staking as of early 2026 typically ranges between approximately two and three point five percent (combined CL and EL), with upside beyond four percent achievable under elevated MEV conditions. Chainlabo cites a ceiling of 4.2% for periods of high network activity, while Pistachio Finance places the typical 2026 range at 2–3% APY. EL rewards exhibit substantially greater variability than the declining but more stable CL component: the 99.99th-percentile EL reward per block proposal exceeds 28 ETH, per Block Scholes research.

 

2.2 Lido stETH – The Rebasing Token

Lido Finance is the largest decentralised liquid staking protocol, controlling approximately twenty-four to twenty-five percent of total staked ETH as of January 2026 – confirmed at 24.12% by the Lido 2025 Annual Report – a figure reflecting material compression from the approximately thirty-two percent share recorded in early 2025, as documented by multiple independent sources. Users may deposit any quantity of ETH into the Lido smart contract system and receive, in return, the stETH token at a one-to-one ratio. stETH is an ERC-20 standard rebasing token: its mechanism for conveying the economic value of staking rewards to holders operates not through a change in price but through a daily automatic adjustment of each holder’s token balance.

The accounting mechanics are as follows, as documented in Lido’s official stETH/wstETH documentation and confirmed by the Lido contract specification. The Lido protocol maintains two internal state variables: totalPooledETH – the aggregate ETH held by the protocol on the consensus layer, including all accumulated rewards – and totalShares – the total number of abstract accounting units issued to depositors. Each user’s effective stETH balance is calculated according to the formula:

userStETHBalance = userShares × (totalPooledETH / totalShares)

Where userShares is constant; totalPooledETH increases daily as staking rewards accrue across all active Lido validators

Once per day, the Lido oracle network submits a report to the protocol reflecting aggregate rewards earned during that oracle period. This report triggers the rebase – a simultaneous recalculation of every stETH holder’s displayed balance across all wallets. No transaction is initiated by, or attributable to, the user. The balance increment is the product of a change to a state variable within the smart contract, not of any transfer of assets to the user’s address.

 

2.3 Lido wstETH – Exchange-Rate Appreciation Without Wallet Events

Wrapped staked ETH (wstETH) was developed by Lido Finance to address the technical incompatibility between stETH’s rebasing property and the fixed-balance accounting assumptions of most DeFi protocols. Lending platforms (Aave), automated market makers (Curve, Balancer), and collateral vaults operate on the premise that a recorded balance will remain unchanged absent a user-initiated transaction. A rebasing token that modifies balances without a user-initiated transaction breaks this assumption and may produce systemic errors in liquidation calculations and yield attribution. wstETH eliminates this incompatibility: its nominal balance in the holder’s wallet does not change, but the quantity of stETH for which each unit of wstETH may be redeemed increases continuously as staking rewards accumulate.

stETH_per_wstETH = totalPooledETH / totalShares

This ratio increases over time as rewards accrue – as of early 2026, approximately 1.23 stETH per wstETH – confirmed by the dedicated Dune Analytics wstETH:stETH rate query, with CoinGecko reporting 1.2080 and Coinbase referencing 1.23 as of late March 2026

The legal significance of this mechanism for the tax analysis is difficult to overstate. When a taxpayer holds wstETH, the following observations are simultaneously and unambiguously true: the nominal balance of wstETH in the holder’s wallet does not change; no token is transferred to the holder’s address; no transaction of any description is recorded on the blockchain; and the staking rewards have not crystallised into a discrete, separable, or directly receivable asset until the holder actively initiates the unwrap transaction – a positive, self-initiated, on-chain burn of wstETH that returns stETH in a quantity exceeding the amount originally deposited. A qualification is warranted: the wstETH token itself – whose value appreciates as rewards accrue – can be deployed as collateral in DeFi protocols (notably Aave), meaning the economic value of accrued rewards is indirectly accessible via the appreciated wstETH without an unwrap. This does not create an income crystallisation event – no discrete, separable asset is received – but the stronger formulation avoids overstating the inaccessibility argument in adversarial proceedings.

 

The Core Distinction

The legally decisive distinction between the three configurations is not one of degree but of kind. Native staking and stETH rebasing each produce at least some form of observable wallet event – in the former, periodic ETH credits; in the latter, daily balance increments. wstETH produces no wallet event of any description during the entire reward-accrual period. The argument for deferral of the income event is, accordingly, strongest for wstETH – and the a fortiori inference from the judicial treatment of stETH to wstETH is, in the Applicant’s submission, irresistible.

 

The Governing Legal Framework: Article 17(1f) PIT Act Post-2019

The Act of 23 October 2018 amending the Personal Income Tax Act (Journal of Laws 2018, item 2193) introduced, with effect from 1 January 2019, a self-contained and, on its face, exhaustive statutory regime for the taxation of virtual currencies. The legislative design was comprehensive by intent: the legislature created a distinct category of capital income (Article 17(1)(11) PIT Act), defined the sole taxable event with particularity (Article 17(1f)), established a flat rate of nineteen percent (Article 30b(1a)), prescribed the methodology for computing the tax base (Article 30b(1b) read with Article 22(14)–(16)), and expressly excluded from the deductible cost base any expenditure attributable to the exchange of one virtual currency for another (Article 23(1)(38d)). The explanatory memorandum to the government bill (Sejm print no. 2860, page 11) characterises the virtual currency provisions as constituting a “complete and self-contained regulation of the subject.”

The central provision is Article 17(1f), which defines “disposal of virtual currency” as the exchange of virtual currency for:
(1) legal tender (prawny środek płatniczy),
(2) goods (towary),
(3) services (usługi),
(4) property rights other than virtual currency (prawa majątkowe inne niż waluta wirtualna)

– or –
(5) the settlement of obligations by means of virtual currency

The textual, systemic, and purposive interpretations of this provision converge upon the same conclusion: the enumeration is exhaustive. The legislature’s deployment of a positive, finite list – rather than an open-ended standard such as “including, without limitation” – signals a deliberate choice to define the taxable event by reference to a closed catalogue. Orthodox Polish statutory interpretation, as consistently applied by the administrative courts, treats such a catalogue as admitting neither analogical extension nor purposive supplementation beyond its express terms.

The structural consequence is that Article 17(1f) operates as a lex specialis displacing general rules of income recognition wherever virtual currency is involved. Article 18 PIT Act – the residual provision governing income from property rights – cannot be invoked as an alternative or supplementary basis for taxing virtual currency transactions, because the specific virtual currency regime forecloses the operation of general law in that domain. Article 11(1) PIT Act – the general provision under which income arises upon the receipt of money, monetary values, or the value of non-cash benefits – remains available as an analytical framework for testing whether actual economic enrichment has occurred, but it cannot independently create a taxable event where Article 17(1f) has not provided one.

 

Pillars of the Legal Argument

Pillar I – The Exhaustive Character of Article 17(1f) as Lex Specialis

None of the events that arise in the course of the three staking configurations satisfies any of the five limbs of Article 17(1f). The analysis is systematic and, in the Applicant’s submission, conclusive: first, no legal tender is received – rewards are denominated and delivered in ETH, stETH, or appreciated wstETH value, none of which constitutes legal tender or is convertible through any mechanism prescribed by statute; second and third, no goods or services are acquired – the validator’s rewards are the product of an automated algorithmic process, not of a bilateral synallagmatic transaction with a counterparty supplying goods or services in exchange for virtual currency; fourth, no non-virtual-currency property rights are acquired – ETH, stETH, and wstETH each satisfy the statutory definition of virtual currency and the receipt of one virtual currency as a consequence of holding another does not fall within this limb; fifth, no pre-existing obligation denominated in virtual currency is discharged.

Since Article 17(1f) establishes the exclusive definition of the taxable event in respect of virtual currency, and since none of the described events satisfies that definition, none gives rise to taxable income at the time of its occurrence. The principle is as simple, and as firm, as statutory text admits.

 

Pillar II – The Constitutional Prohibition on Taxation Without a Calculable Statutory Basis

Article 217 of the Polish Constitution provides that the imposition of taxes, other public charges, and the determination of taxpayers, taxable events, tax bases, rates, and exemptions shall occur exclusively by statute. The Constitutional Tribunal has interpreted this provision, in its judgments of 8 July 2014 (case no. K 7/13) and 29 July 2014 (case no. P 49/13), as requiring not merely a statutory foundation for the existence of a tax obligation but a statutory specification of every essential element of that obligation – including, critically, the moment at which the liability arises and the method by which the tax base is to be calculated. In the Tribunal’s formulation, a tax obligation whose essential elements are not determinable from the face of a statute violates the constitutional principle of completeness of tax legislation (zasada zupełności ustawowej podatku) and thereby infringes Article 217.

The constitutional argument operates with particular force in the present context. Were the administrative authority to hold that staking rewards give rise to income at the moment of accrual, it would be required to specify, for each such event, the monetary equivalent of the reward in Polish zloty. Yet the PIT Act contains no provision specifying a methodology for converting virtual currency into zloty for income-recognition purposes. Article 11(2a) PIT Act, which governs the monetary valuation of non-cash benefits in kind, has no application to virtual currency after 2019: the virtual currency framework is self-contained and does not cross-reference the general valuation rules applicable to other income categories. This legislative silence is not inadvertent – it is the deliberate consequence of the legislature’s decision to defer the income event to the moment of disposal, at which point the proceeds of disposal provide an objective, market-derived measurement of the taxable gain. Any interpretation that locates the income event earlier must be rejected not merely as a matter of statutory construction but as unconstitutional.

 

Pillar III – The Absence of Actual and Definitive Economic Enrichment

Even setting aside the lex specialis argument – which remains the primary and, in this analysis, conclusive ground – the general income recognition rule of Article 11(1) PIT Act independently forecloses the adverse position. Under that provision, income arises upon the taxpayer’s acquisition of an actual and definitive economic benefit that can be incorporated into the taxpayer’s patrimony. As the Warsaw Administrative Court formulated the rule in its 2024 decisions, income arises only when the taxpayer “receives an actual accretion to his patrimony” – one whose value in legal tender “can be determined at the moment of the transaction.”

In the case of native staking rewards and stETH rebase increments, the argument from this pillar is powerful: the received ETH and the incremented stETH balance constitute virtual currency, not money or monetary values within the meaning of Article 11(1), and no statutory conversion mechanism permits their objective valuation in zloty at the moment of accrual. In the case of wstETH, the argument is irresistible: no asset of any description is received by the taxpayer, no balance changes, and the accreted value remains entirely inaccessible – it cannot be expended, pledged, or deployed for any purpose – until the taxpayer actively initiates the unwrap. To characterise unrealised exchange-rate appreciation as “income received” within the meaning of Article 11(1) strains that provision beyond any defensible interpretation.

 

Judicial Authority: A Critical Analysis of the Emerging Case Law

The Polish administrative court jurisprudence on the taxation of staking rewards, while not yet the subject of a definitive Supreme Administrative Court ruling on point, has developed with remarkable speed and consistency since the landmark NSA judgment of March 2022. Four decisions across three appellate districts – Cracow, Warsaw, and Wrocław – have annulled Director of KIS rulings that imposed taxation at the moment of reward accrual, and the reasoning deployed across those decisions is strikingly uniform. That uniformity is not coincidental: the courts cite one another, and each subsequent decision reinforces the interpretive position established by its predecessors.

 

II FSK 1688/19 – Supreme Administrative Court (NSA)  ·  22 March 2022

Held: The exchange of one virtual currency for another virtual currency did not give rise to taxable income in 2018, as there existed no clear statutory basis for determining the monetary value of the resulting enrichment. The Court further observed, in obiter dictum, that even under the post-2019 regime the legislature did not include virtual-currency-for-virtual-currency exchanges within the definition of “disposal” in Article 17(1f) PIT Act – such exchanges therefore remain tax-neutral.

The 2022 NSA judgment does not directly address staking. Its ratio decidendi concerns the pre-2019 legal framework; the observation that Article 17(1f) does not encompass virtual-currency-for-virtual-currency exchanges is obiter dictum. Its legal significance is nonetheless foundational: if even an explicit exchange of virtual currencies of unequal value yields no taxable income, the a fortiori inference for unilateral protocol-automated reward credits is compelling. This inference is an analytical construction – the NSA did not itself address staking – but the lower courts drew precisely this conclusion in the decisions discussed below.

 

I SA/Kr 217/23 – Regional Administrative Court, Cracow  ·  Delegated Proof-of-Stake staking

Annulling Director of KIS ruling no. 0114-KDIP3-1.4011.908.2022.1.MK1. Held: The receipt of newly issued tokens as staking rewards under a Delegated Proof-of-Stake mechanism does not constitute taxable income at the moment of receipt. The administrative authority failed to demonstrate the existence of an “actual economic enrichment” within the meaning of Article 11(1). The absence of a statutory methodology for converting virtual currency into zloty renders it legally impossible to determine the monetary value of any purported enrichment. The Court rejected the application of Articles 18 and 19 PIT Act, holding that since 2019 virtual currency income falls within the regime of Article 17(1)(11) read with Article 17(1f), not the general provisions. Since no income arises at the moment of receipt, the application of Article 19 PIT Act as a basis for quantification is equally without foundation.

 

Cracow Administrative Court – I SA/Kr 217/23 (19 April 2023)

The Cracow Court was the first to annul a Director of KIS ruling on staking and to develop the argument from the absence of a statutory conversion methodology. While the Court did not expressly invoke Article 217 of the Constitution or cite the Constitutional Tribunal judgments K 7/13 and P 49/13, its reasoning – that the impossibility of determining the monetary value of a purported enrichment precludes income recognition – implicitly engages the constitutional principle of completeness of tax legislation. The systematic constitutional analysis, with direct citation of Article 217 and the Constitutional Tribunal’s case law, was subsequently developed by the Warsaw Administrative Court in its March 2024 decisions. The Cracow Court’s categorical rejection of Article 18 as an alternative basis closed a route that the Director of KIS had been prepared to invoke as a fallback.

 

III SA/Wa 178/24 and 179/24 – Regional Administrative Court, Warsaw  ·    21 March 2024  ·  Lido stETH + native ETH PoS

Annulling impugned Director of KIS rulings in their entirety. Held: The receipt of rewards in the form of stETH tokens through Lido Finance liquid staking, and the receipt of rewards through individual (solo) Ethereum PoS staking, do not constitute taxable income at the moment of receipt. Article 17(1f) PIT Act establishes a complete catalogue of taxable disposal events; the receipt of virtual currency as a staking reward falls outside that catalogue. Gas fee and Swaps licensing fee payments in virtual currency do not give rise to taxable income from virtual currency disposal. Director of KIS rulings annulled in their entirety.

The two Warsaw decisions are, for practising lawyers, the most significant in the emerging line for three reasons. First, they address both Lido stETH and native individual ETH staking by name – eliminating any argument that earlier decisions could be distinguished on the ground that they concerned different consensus mechanisms. Both decisions were rendered on the same day, by the same judicial panel, with identical legal reasoning, for different appellants (case no. 178/24 – A.R.; case no. 179/24 – J.Z.), each challenging a separate Director of KIS ruling. Second, the Court’s formulation of the exhaustive-catalogue argument is the most categorical to date. Third, the Court conducted the first systematic constitutional analysis in the staking context, directly invoking Article 217 of the Constitution, Constitutional Tribunal judgments K 7/13 and P 49/13, and the principle that taxation without a calculable statutory basis is constitutionally impermissible:

“In the Court’s assessment, events other than those expressly enumerated [in Article 17(1f)] cannot give rise to income from the disposal of virtual currency. This interpretive result follows from the literal reading of the provision and is further supported by purposive and systemic analysis.” – Warsaw Administrative Court, III SA/Wa 179/24

“It is not permissible, as the administrative authority argued, to derive a tax liability for the receipt of virtual currency rewards from the text of Article 18 PIT Act. As has already been explained, income from virtual currency is classified under the source designated as capital gains. Article 17(1f) PIT Act exhaustively enumerates all events subject to taxation on account of the disposal of virtual currencies.” – Warsaw Administrative Court, III SA/Wa 179/24.

The Court also invoked the constitutional dimension with explicit force, holding that acceptance of the Director of KIS’s position “would lead to arbitrariness in the determination of the quantum of the tax liability by administrative authorities, including through unwarranted estimation of that value” – an outcome incompatible with the constitutional completeness requirement of Article 217.

 

I SA/Wr 413/23 – Regional Administrative Court, Wrocław  ·  6 December 2023

Annulling Director of KIS ruling concerning the taxation of rewards from cryptocurrency staking. The Court expressly held that, from 2019 onward, virtual currencies are not “property rights” within the meaning of the PIT Act – they constitute a distinct category of capital income under Article 17(1)(11). The exchange of virtual currencies for other virtual currencies – as not enumerated in Article 17(1f) – is tax-neutral. The acquisition of virtual currency as a staking reward, absent a disposal event within the statutory definition, does not give rise to taxable income.

 

An Assessment of the Judicial Trajectory

Four decisions across three years and three judicial districts form a coherent and, on any realistic assessment, consolidating line. The courts differ in their emphasis – the Cracow Court develops the argument from the absence of a statutory conversion methodology; the Warsaw Court adds the systematic constitutional analysis and the most categorical formulation of the exhaustive-catalogue thesis; the Wrocław Court contributes the additional finding that virtual currencies are not “property rights” under the PIT Act, reinforcing the geographic breadth of the line – but the outcome is uniform: administrative court rulings imposing taxation at the moment of reward accrual are annulled. The courts cite one another, reinforcing the authority of each successive decision.

Absent a Supreme Administrative Court ruling squarely addressing staking – which, given the pace at which the Warsaw and Cracow cases will reach cassation review, should be expected within the period 2025 to 2027 – the current trajectory strongly favours the taxpayer-protective interpretation. Any Director of KIS ruling adverse to taxpayers’ positions risks prompt annulment by the relevant administrative court, at attendant cost and delay to both the taxpayer and the public administration. The Director of KIS would, moreover, be departing from his own settled practice, as the following section demonstrates.

 

Cost of Acquisition and the FIFO Methodology

Even under the taxpayer-favourable interpretation – income recognised exclusively upon disposal – the correct determination of the deductible cost of acquisition is critical to the calculation of the taxable base. The legal framework and the practical implications of that framework warrant separate analysis.

 

The Statutory Framework – Articles 22(14)–(16) PIT Act

The deductible costs of acquiring virtual currency – which are offset against disposal proceeds in computing the taxable capital gain – comprise documented expenditures directly incurred in acquiring the virtual currency in question (Article 22(14) PIT Act). Costs are allocated on a first-in, first-out (FIFO) basis: virtual currencies acquired earliest are treated as disposed of first (Articles 22(15) and (16)). A provision of considerable practical importance: costs not deducted in a given tax year carry forward to the following year – a mechanism that, for accumulation-oriented stakers, can produce a multi-year cost pool that substantially reduces taxable income upon eventual disposal.

 

The Symmetry Principle Under the Adverse Interpretation

If, contrary to the foregoing legal argument, the tax authority were to conclude that the value of staking rewards constitutes taxable income already at the moment of their receipt, that same value should then be recognized for tax purposes as the acquisition cost upon the subsequent disposal of those tokens.

This does not follow solely from the literal wording of Article 22(14) of the Personal Income Tax Act, which refers to documented expenses directly incurred for the acquisition of virtual currency, but rather from a systemic interpretation of the provisions governing the taxation of virtual currencies and from the need to preserve coherence in the tax treatment of the transaction.

In practical terms, this means that prior recognition of income at the moment the reward is accrued or received cannot justify taxing the same economic value again upon disposal of the token without simultaneously recognizing a corresponding tax cost.

Any contrary approach would result in double taxation of the same economic gain, which would be inconsistent with systemic interpretation and with the arguments advanced in disputes concerning the taxation of staking rewards.

 

Documentation

In practice, taxpayers engaged in staking activity should: export complete transaction histories from blockchain explorers (Etherscan CSV exports) and portfolio analytics tools (Koinly, CoinTracking, Rotki); maintain records of ETH/PLN market rates on the date of each acquisition transaction; track consensus-layer and execution-layer rewards separately, given their distinct temporality and accessibility profiles; and archive annual position summaries for cross-reference against DAC8 reports submitted by CASPs from 2026 onward. The principle that the taxpayer’s own records should be at least as granular as the data available to the tax authority from third-party reporting is, in the new DAC8 environment, both prudent and increasingly important.

 

The Functional Gap – Limits of the Judicial Argument in the Age of DeFi Composability

The analysis thus far has led to a conclusion favourable to the taxpayer: no staking event satisfies any limb of Article 17(1f), income arises exclusively upon disposal, and the constitutional principle of completeness independently forecloses taxation without a calculable statutory basis. Four administrative court decisions confirm this position. The legal reasoning is sound. The question that any rigorous adviser must nonetheless confront – and that the existing jurisprudence has left unanswered – is a different one: does the foundational assumption upon which the entire judicial line rests correspond to the economic reality of DeFi in 2026?

 

The hidden assumption: staking as passive holding

The rulings of the Cracow, Warsaw, and Wrocław Courts rest upon an unstated premise – that staking is a linear activity. The taxpayer deposits cryptocurrency, accumulates rewards, and at some unspecified future point, disposes of the accumulated position. In this model, deferral is a logical consequence: since no event in the Article 17(1f) catalogue occurs between deposit and disposal, there is no taxable moment. The court sees a simple timeline: entry → accumulation → exit. Only exit is taxed.

This model accurately described the staking landscape of 2022–2023, when the first decisions were rendered. It does not describe what sophisticated market participants actually do in 2026 – and that discrepancy is the source of a functional gap that demands candid analysis.

 

DeFi composability:
staking → collateralisation → borrowing → monetisation

The defining property of the DeFi ecosystem is composability – the capacity of protocols to use each other’s tokens as building blocks for progressively more complex financial structures. In the staking context, composability creates a pathway that the administrative courts have not had occasion to consider:

Step 1. The taxpayer deposits ETH into the Lido protocol and receives stETH (or wstETH). A tax-neutral event – confirmed by the WSA decisions.

Step 2. The taxpayer deposits stETH (or wstETH) as collateral in a lending protocol – Aave V3, Spark, Compound, or Morpho. No disposal occurs: the token remains the taxpayer’s property, merely locked in a lending smart contract as security for repayment.

Step 3. Against the collateral, the taxpayer borrows a stablecoin (USDC, DAI, USDT) – a digital equivalent of the United States dollar, convertible one-to-one into fiat currency.

Step 4. The taxpayer converts the stablecoin to PLN via an exchange or payment gateway. Cash is in hand.

The end result: the taxpayer holds zloty, and the staking position remains intact. None of the four steps satisfies the “disposal” requirement of Article 17(1f) – the Lido deposit is a VV→VV exchange, the Aave collateralisation is not a disposal, the borrowing is not a disposal, and the stablecoin-to-PLN conversion is a disposal of borrowed funds, not of staking rewards. Under the current interpretive framework, none of these steps generates income from staking.

 

wstETH as a perpetual tax deferral machine

The mechanism becomes still more refined in the case of wstETH – the token whose nominal balance does not change, but whose market value rises as staking rewards accumulate. The appreciation of the collateral automatically increases the taxpayer’s borrowing capacity. Each day, as the stETH-to-wstETH exchange rate increases by a fraction of a percent, the lending protocol recognises a higher collateral value and permits a further tranche of borrowing – without any transaction initiated by the user.

The taxpayer never disposes. Never realises a gain. Never triggers an event within the Article 17(1f) catalogue. And yet commands a growing stream of cash – financed by the appreciation of staking rewards, borrowed against their security, and spent without restriction. So long as the collateral value exceeds the loan value (and at the loan-to-value ratios of 70–80% typical of lending protocols), the cycle can continue indefinitely.

This is the precise DeFi equivalent of the buy-borrow-die strategy known in American tax planning – the structure in which the owner of appreciated assets never sells, but borrows against a growing portfolio, avoiding realisation of capital gain until death (and the step-up in basis that eliminates it). The difference is that in DeFi the cycle is automated, operates around the clock, and requires no banking intermediary.

 

Why the courts did not see this – and why it does not undermine their rulings

The factual descriptions presented in the ruling applications – in both the Cracow case (exchange-based DPoS staking) and the Warsaw cases (Lido stETH and native solo staking) – described exclusively the simple sequence: deposit → accumulation → question about the taxable moment. None of the applicants described the second stage: deployment of rewards as collateral in a lending protocol. The courts adjudicated within the boundaries of the facts presented to them – and within those boundaries, they adjudicated correctly.

This does not alter the fact that the courts’ reasoning – grounded in the argument that “no actual enrichment” occurs and that “no statutory valuation methodology” exists – loses its persuasive force when the taxpayer has, in economic substance, monetised staking rewards through DeFi lending. The enrichment is actual (cash in a bank account), measurable (loan value denominated in USD or PLN), and definitive (money spent). The only reason the tax system does not see it is that Article 17(1f) defines the taxable event through the prism of disposal – and a loan is not a disposal.

 

Strategic implications: risk and responsibility

For the tax practitioner, this analysis yields three conclusions, none of them comfortable.

First, the current interpretation of Article 17(1f), while correct de lege lata, creates a functional gap permitting permanent deferral of staking income – not merely until the moment of disposal, but potentially in perpetuity, through the mechanism of loans secured by staking tokens. This is a consequence that the legislature of 2018 – designing the virtual currency taxation regime – assuredly did not foresee.

Second, the gap is susceptible to legislative intervention. An amendment to Article 17(1f) adding a sixth limb – for example, “the deployment of virtual currency as security for a financial obligation” – would suffice to close the buy-borrow-die pathway in DeFi. The Ministry of Finance, implementing CARF and DAC8, will have access to the data necessary to identify such structures. The question is not whether, but when, the legislature will notice.

Third – and most important from the perspective of advisory ethics – the existence of a functional gap does not mean it should be exploited uncritically. A taxpayer who uses the staking → collateral → borrow → monetisation pathway operates within the law – but operates at a boundary whose permanence is uncertain. Rigorous advice requires presenting the client with the full picture: the strength of the argument de lege lata, its structural vulnerability de lege ferenda, and the necessity of securing the position with an individual ruling that covers not only staking itself but also the deployment of staking tokens in lending protocols.

Intellectual honesty compels a direct statement: the administrative courts correctly identified that Article 17(1f) does not encompass the accrual of staking rewards. They did not, however, have occasion to confront the question of what happens when those rewards – formally untaxed – become the foundation of a financial structure generating actual, measurable, and expendable income without any event qualifying as “disposal.” That question remains open – and it is in that question that both the greatest risk and the greatest advisory value of this analysis reside.

 

International Comparative Context: Staking Taxation Worldwide

Poland’s judicial position – deferring the taxable event to the moment of disposal – places it in a global minority. International approaches to staking taxation cluster into three models: (1) the receipt model (majority of jurisdictions), (2) the disposal/fiat-conversion model (minority), and (3) the zero-tax model (tax-free jurisdictions). Poland, under its current judicial interpretation, operates de facto in an extended variant of the second model.

 

United States

The IRS codified its position in Revenue Ruling 2023-14: staking rewards constitute gross income in the taxable year the taxpayer acquires “dominion and control” over the cryptocurrency. FMV in USD at the date control is acquired constitutes both ordinary income and the cost basis for subsequent capital gain. The Jarrett v. United States litigation – in which the taxpayer asserts that newly created staking tokens are “manufactured property” taxable only at disposition – has not produced a merits ruling as of March 2026. The Crypto Council for Innovation is pressing Congress to clarify that staking rewards are taxed at sale, not creation. Rate: ordinary income 10–37%; subsequent disposal at LTCG rates 0/15/20%.

 

United Kingdom

HMRC treats staking rewards as miscellaneous income at the point of receipt, valued in GBP. Where staking is conducted commercially, HMRC may reclassify it as trading income attracting National Insurance Contributions. A second CGT event (18–24%) arises on disposal. HMRC published a summary of responses to its DeFi taxation consultation in November 2025.

 

Germany

The BMF letter of 6 March 2025 (updating the 10 May 2022 letter) classifies staking income under §22 No. 3 EStG (income from other services), taxable at receipt at the personal income rate up to 45% plus 5.5% Solidarity Tax. A statutory de minimis exemption applies: total miscellaneous income (staking + mining + lending) below €256 per year is entirely exempt. The standard one-year CGT-free holding period applies (the proposal to extend to ten years was definitively abandoned). Germany implements DAC8 through the new Kryptowerte-Steuertransparenzgesetz (KStTG).

 

Austria

Since 1 March 2022, crypto assets are treated on par with equities and bonds: a flat 27.5% special capital income tax applies. Crypto-to-crypto exchanges are not taxable events – only conversion to fiat triggers the 27.5% rate. Staking falls under the same regime. Austria’s treatment is structurally closest to Poland’s judicial position, though based on an explicit statutory classification rather than a gap-analysis argument.

 

France

France applies a 30% flat tax (Prélèvement Forfaitaire Unique): 12.8% income tax plus 17.2% social charges. Staking rewards are classified as revenus de capitaux mobiliers and must be declared at FMV on the date of receipt.

 

Italy

The Agenzia delle Entrate, in its response to interpretive query No. 437/2022, ruled that staking income constitutes reddito di capitale subject to a 26% substitute tax. Critically, Italy established an explicit valuation methodology – the average exchange rate on the last day of the month in which the reward was received – resolving the constitutional-grade ambiguity that constitutes one of Poland’s strongest arguments.

 

Portugal

Portugal presents one of the most taxpayer-friendly regimes in the EU. Staking rewards are classified under Category E (investment income) of the IRS code – no immediate taxation when received in crypto; a 28% rate applies only at fiat conversion (35% from blacklisted jurisdictions). Separately, capital gains on crypto held for more than 365 days are fully exempt. Portugal’s statutory classification of staking represents the closest international parallel to Poland’s judicial position.

 

Switzerland

Private investors pay no capital gains tax. Staking income is taxed as ordinary income at federal and cantonal rates. An annual wealth tax of approximately 0.1–1% (canton-dependent) applies to all crypto holdings as movable assets.

 

Malta, Canada, Australia

Malta taxes staking rewards progressively (0–35%) at receipt; non-domiciled residents benefit from a remittance basis. Canada (CRA) treats staking rewards as taxable income at receipt at FMV in CAD. Australia (ATO) classifies them as ordinary income, with a 50% CGT discount available for assets held longer than 12 months.

 

UAE and Singapore – Zero-Tax Jurisdictions

The UAE imposes no personal income or capital gains tax; staking, mining, and trading generate no liability for individuals (9% CIT applies only at the business level). Singapore similarly imposes no capital gains tax on private investors.

 

Poland’s Position in Global Context – Synthesis

Poland’s argument is structurally unique: it relies neither on a policy exemption, a de minimis threshold, nor a statutory deferral rule, but on the conclusion that the definition of the taxable event itself (Article 17(1f)) does not encompass staking accruals. The constitutional reinforcement (Article 217 – absence of a statutory valuation methodology) adds a second, independent layer. No other surveyed jurisdiction constructs an analogous argument. Most jurisdictions resolve the valuation problem through analogical rule application (FMV at receipt under general income recognition rules), administrative guidance, or explicit statutory formulae (Italy’s monthly average rate). Poland’s legislative silence – intended to be comprehensive – paradoxically creates the most taxpayer-favourable outcome in the European Union. This position is, however, provisional: it depends on NSA confirmation and may be altered by legislative amendment to Article 17(1f).

 

Trends, Open Questions, and the Legislative Horizon

The Anticipated NSA Ruling on Staking

As of the date of this article, no Supreme Administrative Court judgment squarely addresses the taxation of staking rewards. The Warsaw Administrative Court decisions of March 2024, if appealed by the Director of KIS through cassation proceedings, would generate a definitive NSA ruling within the period 2025 to 2027. Given the categorical language of the lower court decisions, their alignment with the NSA’s own 2022 ruling on the exclusive character of Article 17(1f), and the absence of any contrary statutory development, the trajectory towards a taxpayer-favourable NSA outcome appears – while no such prognosis is certain – relatively well-supported. A contrary NSA ruling would represent a significant departure from both the established judicial line and the NSA’s own doctrinal framework, and would almost certainly prompt legislative intervention to clarify the statutory text.

 

MiCA, CASP Authorisation, and the Regulatory Infrastructure

Regulation (EU) 2023/1114 (MiCA) and the DAC8 Directive together constitute a new stratum of supervisory and fiscal oversight over the crypto-asset market. CASPs authorised under MiCA are subject to DAC8 transaction-data reporting obligations from 2026, with the first automatic exchanges of information between Member States expected by autumn 2027. A necessary qualification: DAC8 in its current form mandates reporting primarily of transaction-level data – fiat exits, crypto-to-crypto exchanges, and transfers – rather than accrual-side staking income as a discrete category. The reporting of staking income at the platform level is not yet uniformly obligatory under the directive text, and may evolve at the national implementation level. Nonetheless, the registration of staking platforms as CASPs creates an evidentiary infrastructure that tax authorities can cross-reference against filed returns, even where reward-accrual data is not automatically transmitted in the first exchange cycle. The combined effect is to transform compliance from a voluntary exercise into one backed by progressively expanding third-party verification. Taxpayers who have not previously filed returns disclosing staking income should take legal advice on their exposure and, where appropriate, consider voluntary disclosure proceedings under Article 16a of the Fiscal Penal Code before the relevant CASP data reaches the authorities.

 

Restaking Protocols: The Next Interpretive Frontier

Liquid restaking protocols – EigenLayer, Symbiotic, and their successors – add a further layer of analytical complexity to an already technically demanding landscape. In a restaking structure, staked ETH (or a liquid staking token such as stETH) is simultaneously re-deployed as economic collateral for additional network services (Active Validator Sets, or AVSs). Rewards from restaking may be denominated in tokens native to the restaking protocol rather than in ETH, introducing new assets of uncertain classification and new timing questions. The analogy to native staking is strong, but the mechanisms – including novel slashing conditions and cross-protocol dependencies – are materially different. At the time of writing, no Director of KIS ruling and no administrative court judgment directly addresses restaking. Taxpayers engaged in restaking protocols should seek an individual ruling as a matter of priority, and should not assume without independent analysis that the settled practice confirmed in the staking context extends without qualification to restaking.

 

Potential Legislative Reform

The Ministry of Finance has on several occasions signalled interest in a reform of the virtual currency provisions of the PIT Act, including through the transposition of CARF obligations into domestic law. DAC8-generated data – covering primarily fiat exit events and CASP-registered staking platform activity – will provide tax authorities with an increasingly granular evidentiary basis for cross-referencing staking positions against declared income. An amendment to Article 17(1f) that expanded the catalogue of taxable disposal events – for example, by treating reward accruals as income – would alter the analysis set out in this article de lege ferenda. Until such a legislative change is enacted, however, the position de lege lata remains as described: the exhaustive catalogue of Article 17(1f) forecloses the adverse interpretation, and the judicial and administrative authorities confirm that conclusion.

 

Practical Recommendations

File an individual ruling application (wniosek o interpretację indywidualną) pursuant to Article 14b of the Tax Ordinance Act, covering each mechanism as a separate question. The filing fee is PLN 40 per question – PLN 160 for the four questions addressed in this analysis. The ruling, once issued, is binding on the Director of KIS and immunises the applicant from tax assessment, penalties, and interest for the period to which it applies. The quality of the description of facts – which must be technically precise, numerically specific, and legally complete – determines the scope of the protection conferred. A description that omits the distinction between CL and EL rewards, or that fails to specify the wstETH exchange-rate mechanism with precision, may produce a ruling of narrower scope than intended.

Maintain, as a matter of routine, complete blockchain transaction histories exported from Etherscan (CSV format) or equivalent explorers, supplemented by market-rate data from CoinGecko or exchange API records for the date of each acquisition. Compute the FIFO cost basis for each disposal event. Dedicated portfolio accounting tools – Koinly, CoinTracking, Rotki – provide adequate functionality for most taxpayers. The fundamental principle: DAC8 reports submitted by CASPs from 2026 onward will provide the tax authority with transaction-level data. The taxpayer’s own records should be at least as comprehensive.
