Tax Overpayment Recovery in Poland. A Practitioner’s Guide for Foreign Clients

Tax Overpayment Recovery in Poland. A Practitioner’s Guide for Foreign Clients

2026-05-18

The recovery of overpaid Polish tax is, on its surface, a simple proposition: the State has received what it should not have, and the taxpayer is entitled to its return. Beneath that surface, the Polish Tax Ordinance (“Tax Ordinance”; the Polish equivalent of a general procedural code governing all national taxes, hereinafter the “OrdPU”) constructs a regime of remarkable intricacy. Articles 72 to 80 OrdPU organise the matter into definitional categories, moments of formation, procedural avenues, repayment deadlines, interest entitlements, and ultimate extinction. Foreign clients seeking to recover Polish tax routinely discover that what would be a straightforward refund claim in their home jurisdiction is, in Poland, a multi-layered procedural exercise.

This guide is intended for foreign in-house counsel, international tax advisors, and cross-border practitioners who need a working understanding of the Polish overpayment regime, whether the underlying tax is VAT, property tax, personal income tax, corporate income tax, withholding tax, excise duty, or transfer tax on civil-law transactions. The framework is the same; the specific applications differ.

 

What constitutes an overpayment under the Tax Ordinance

Article 72 § 1 OrdPU defines a tax overpayment by reference to four substantive configurations. An overpayment exists when (i) a taxpayer has paid an amount in excess of, or without legal basis for, the tax due; (ii) a tax remitter (the Polish “płatnik”, a third party statutorily charged with withholding) has collected from the taxpayer an amount exceeding what was due; (iii) such a remitter or a tax collector has paid an amount under a decision establishing the remitter’s liability that turned out to have been wrongly determined; or (iv) a third party or a successor in interest has paid an amount under a decision on inherited tax liability that proved erroneous.

Article 72 § 1a and § 1b treat as equivalent to overpayments the refundable balances arising from certain personal and corporate income tax reliefs (notably the child allowance and the R&D super-deduction). Article 72 § 2 extends the regime, in carefully circumscribed fashion, to payments wrongly attributed to interest, to tax arrears, to penalty interest on advance instalments, and to deferral fees. The conceptual core is the same throughout: the State has received what it is not entitled to retain.

 

When the overpayment arises

The moment of formation matters because it determines the start of interest accrual and, in certain configurations, the running of limitation periods. Article 73 § 1 OrdPU recognises five fact-based moments: payment, withholding, payment under a remitter’s liability decision, the remitter’s overpayment relative to amounts actually withheld, and payment by a third party or successor under a flawed liability decision. Article 73 § 2 adds a separate “act-based” mode: in income tax, excise, and State enterprise profit distributions, the overpayment arises upon the filing of the relevant annual or periodic return. The distinction is consequential rather than purely doctrinal.

Article 74 OrdPU provides a special regime where the overpayment results from a ruling of the Polish Constitutional Tribunal or the Court of Justice of the European Union. In such cases, the taxpayer determines the amount and files a refund application together with a corrected return, displacing the default rule that the tax authority quantifies the overpayment. The cross-border practitioner will recognise this as the operative provision for refunds following CJEU judgments on the compatibility of Polish tax measures with Union law (see also the preliminary reference procedure and the binding force of CJEU jurisprudence).

 

Procedural avenues for claiming the refund

The Tax Ordinance bifurcates the procedural treatment of overpayments according to their origin. Overpayments arising from the taxpayer’s own return require no separate application: the authority refunds within the statutory deadline running from filing. Overpayments arising from any other source require the formal step contemplated by article 75 § 1 OrdPU, namely an application to declare the overpayment (“wniosek o stwierdzenie nadpłaty”), accompanied by a corrected return where applicable. Standing extends to taxpayers, remitters, tax collectors, the constituent companies of former tax-consolidated groups, and the representative of former VAT groups.

Where the application and the underlying corrected return are unproblematic, the authority effects the refund without issuing a formal declaratory decision (article 75 § 4). Where they are not, the authority issues a reasoned decision determining the proper amount of the tax liability and, within that determination, declaring the overpayment or refusing the application (article 75 § 4a). The practical consequence is that the application is, in form, a request for a refund but, in substance, a request to reopen the quantification of the underlying liability.

A critical procedural trap, frequently overlooked in cross-border matters, is the suspension imposed by article 79 § 1 OrdPU. Where a tax audit, customs and fiscal control, or formal tax proceedings are pending in respect of the same liability, no application to declare an overpayment may be brought. If the application has been filed and the authority subsequently opens such proceedings of its own motion, the refund claim is absorbed into the broader proceedings. Foreign counsel timing a recovery strategy in Poland would do well to verify the absence of pending or imminent audit activity before filing.

 

Deadlines for repayment

Article 77 OrdPU prescribes no fewer than fourteen distinct repayment deadlines, each keyed to a particular procedural posture. The thirty-day deadline is by far the most common, applying in six configurations under article 77 § 1 read together with article 76c second sentence: (i) following a new decision issued after annulment of an earlier one; (ii) following a declaratory decision; (iii) following an annulment that requires no new decision; (iv) following a refund application based on a Constitutional Tribunal or CJEU ruling under article 74 OrdPU; (v) by reference to the date the relevant ruling enters into force; and (vi) under a declaratory decision in the article 75 § 1 procedure.

A two-month deadline applies to overpayments declared on application accompanied by a corrected return, subject to a floor: the deadline may not expire earlier than three months from the filing of the underlying return (forty-five days for personal income tax returns filed electronically). The three-month and forty-five-day deadlines themselves govern the principal annual income tax return scenarios, with the shorter period reserved for electronic filings. A six-month deadline applies under article 77 § 2a OrdPU to refunds linked to anti-avoidance proceedings under article 119g § 1 point 3, alongside a three-month deadline where the taxpayer has filed a request to assume the proceedings.

Where the authority fails to issue a new decision within three months of an annulment by an administrative court with a final and binding ruling, article 77 § 4 OrdPU requires the refund to be made “without undue delay.” This last provision is the foreign client’s principal hedge against bureaucratic inertia following a successful judicial challenge.

 

Interest on overpayments

Article 78 § 1 OrdPU prescribes interest on overpayments at the same rate as the default interest charged on tax arrears, an architectural symmetry between the State’s exposure and the taxpayer’s. The threshold below which interest is not payable (article 78 § 2) is defined by reference to twice the cost of an administrative reminder, an amount sufficiently trivial that the rule rarely operates in commercial matters.

The accrual rules are differentiated by category of overpayment. Where the overpayment arose from the annulment of a decision and the authority “contributed to the cause” of that annulment, interest runs from the date the overpayment formed, that is, the date of payment (article 78 § 3 point 1). Where the authority did not so contribute, interest runs only from the date the new decision was issued. The “contribution” clause is the principal battleground in interest disputes: in any case where the underlying error was one of legal interpretation by the authority, contribution is, in practical terms, manifest. The Polish administrative courts have developed a substantial body of case law on the subject, and a successful challenge to a partial-period interest award is by no means uncommon.

Where the overpayment is declared on application (article 78 § 3 point 3), interest accrues from the date of the application together with the corrected return in three specifically enumerated situations: (a) non-payment within thirty days of the declaratory decision; (b) non-issuance of a declaratory decision within two months of the application; and (c) non-payment within the deadline of article 77 § 1 point 6. In situations (b) and (c), interest is forfeited where the delay is attributable to the taxpayer’s own conduct, an exception that authorities invoke liberally and that requires careful procedural hygiene to neutralise.

Article 78 § 5 OrdPU governs the special case of overpayments arising from Constitutional Tribunal or CJEU rulings. Interest runs for the full period from formation to refund, provided the taxpayer files the refund application before the ruling enters into force or within thirty days thereafter. Filing later truncates the interest period to the thirtieth day after the ruling, a costly limitation in matters of substantial age. Foreign claimants who have been pursuing parallel litigation in their home jurisdictions, or who have been awaiting the outcome of a Polish reference, should diarise this deadline with care.

 

Extinction of the right to claim

Two limitation regimes converge. Article 79 § 2 OrdPU extinguishes the right to file an application for a declaration of overpayment, and the right to file an application for the refund itself, upon expiry of the limitation period applicable to the underlying tax liability (generally five years from the end of the year in which the tax fell due, subject to tolling and interruption). Critically, where the application has been filed before expiry, the authority may still issue the declaratory decision after expiry (article 79 § 3). Timely filing thus locks in the substantive right.

Article 80 § 1 OrdPU then imposes a second, parallel limitation on the right to be paid the amount of an already-declared overpayment: five years from the end of the year in which the refund became due. The same period extinguishes the right to apply for set-off against future liabilities. Filing of any of the three relevant applications interrupts the running of this second period (article 80 § 3). The practical conclusion is that a foreign claimant who learns, years after the fact, that an overpayment may exist must move quickly twice: first, to defeat the general limitation, and second, to ensure that the refund is actually obtained within the residual five-year window from declaration.

 

Set-off and the ordering rules

Article 76 § 1 OrdPU prescribes that the overpayment, together with its accrued interest, is set off ex officio against tax arrears, against interest accrued thereon, against penalty interest on advance instalments, against the costs of administrative reminders, and against current tax liabilities. Only where none of these exist does the authority refund the balance. The taxpayer may also apply for the overpayment to be carried forward against future liabilities, a particularly useful option in VAT contexts where ongoing input tax credits make immediate refund less attractive.

Set-off decisions take the form of an order subject to a formal complaint (“zażalenie”), and the set-off itself takes priority over the enforcement of garnishment orders by private creditors (article 76 § 2a). The provision is a familiar one to insolvency practitioners advising on the relative ranking of fiscal and commercial claims against Polish debtors.

 

Overpayments arising from administrative error

The economically most significant overpayment claims are those arising from the subsequent invalidation of a constitutive tax assessment, particularly in property tax, inheritance and gift tax, and excise duty. The typical procedural path runs through the reopening of tax proceedings under article 240 et seq. OrdPU, concluding in a new decision that lowers the liability and establishes the resulting overpayment. A point of considerable significance to foreign clients is that the five-year period of article 68 OrdPU (limitation on the issuance of a constitutive assessment) does not preclude the issuance of a decision lowering an existing constitutive assessment, even decades after the underlying tax year. The Supreme Administrative Court has held, in a settled line of authority (judgment of 11 March 2014, II FSK 879/13; judgment of 15 September 2011, II FSK 507/10), that a lowering decision does not create a new obligation but merely corrects the quantum of one already in existence. The doctrinal foundation is consistent across leading commentaries.

In claims of this character, the “contribution” clause of article 78 § 3 point 1 OrdPU acquires particular weight: where the authority issued a substantively flawed assessment, contribution is, on the face of it, attributable to the State, and interest accrues from the date of payment. Resistance from the authority on this point is common but rarely sustainable on judicial review (see also State liability).

 

Category-specific applications

Value-added tax. The most frequent VAT overpayment configurations are: (i) excess input tax over output tax, refundable under article 87 of the Polish VAT Act (a regime that operates parallel to, and largely independently of, the general overpayment provisions of the Tax Ordinance, see VAT refunds in Poland); (ii) overpayment following a correction increasing recoverable input tax; (iii) overpayment following a rate correction in business-to-consumer transactions documented by fiscal receipts rather than VAT invoices, a question resolved by the CJEU in C-606/22 (judgment of 21 March 2024) and, in implementation, by the Supreme Administrative Court in case I FSK 1225/18 (judgment of 26 June 2024); and (iv) overpayment following CJEU rulings invalidating the underlying Polish provision. The C-606/22 line is of particular interest to foreign-owned retail, fitness, and hospitality operations in Poland that have for years applied the standard rate to services attracting a reduced rate.

Property tax. Overpayments most often arise from errors in the initial assessment by the municipal authority: misclassification of premises as commercial rather than residential, erroneous inclusion of common areas, application of the wrong temporal version of the governing statute, or inflated surface measurements. The standard remedial path is reopening of proceedings, with reliance on the article 68 OrdPU jurisprudence noted above.

Personal and corporate income tax. The principal patterns are (i) refunds from annual returns where advance payments exceeded the final liability, processed automatically; and (ii) refunds following correction of returns to reflect previously unclaimed reliefs (R&D super-deduction, IP Box, child allowance, thermo-modernisation relief). A separate regime governs withholding tax refunds, with particular complexity in beneficial ownership and treaty-shopping scenarios.

Inheritance and gift tax. Overpayments typically follow the modification of a constitutive assessment, whether through correction of asset valuations, the surfacing of previously undisclosed estate liabilities, or the proper application of the so-called zero-group exemption for closest relatives. Cross-border successions, particularly where Polish-situated assets are held by non-resident heirs, frequently produce overpayments of this type.

Excise duty and transfer tax. Excise overpayments commonly arise from reclassification of products or proper application of exemptions, and not infrequently from CJEU rulings on the conformity of Polish excise rules with the Energy Directive. Transfer tax overpayments arise from re-characterisation of transactions or from belated application of statutory exemptions (most often the family member exemption and the share-deal exemption).

 

Common pitfalls

Four pitfalls recur in cross-border practice. First, the conflation of the application deadline with the refund deadline: timely filing under article 79 § 3 OrdPU secures the right but does not guarantee speed, and the secondary five-year limitation of article 80 § 1 must thereafter be policed. Second, the underestimation of the “contribution” clause, which the authority routinely invokes to truncate interest entitlements. Third, the procedural risk of filing during a pending or imminent audit, which absorbs the application into the broader proceedings under article 79 § 1. Fourth, the unsystematic treatment of the four available refund modalities (bank transfer, postal order net of costs, cash disbursement, set-off), each with its own tactical consequences.

Where the overpayment claim requires contested proceedings, whether by way of reopening, appeal to administrative courts, or CJEU reference, foreign clients are well-served by engaging Polish counsel with established practice in cross-border tax recovery (see our representation in tax disputes and tax litigation services).
