Summary
-
Poland’s Supreme Administrative Court reportedly held in resolution I FPS 2/26 that, where the tax authority successively extends a VAT-refund deadline, an administrative court generally reviews only the extension decision specifically challenged by the taxpayer, rather than automatically examining every earlier extension relating to the same reporting period.
-
Earlier extension decisions that were not challenged may therefore continue to produce legal effects. According to the press reports, an important exception remains where an earlier decision has a fundamental legal defect, including where it was issued or served only after the applicable refund deadline had already expired.
-
Businesses should treat every VAT-refund extension as a separate procedural event. A decision not to challenge an early extension may restrict the arguments available later, even if the authority subsequently adopts further extensions. Central tracking of refund dates, service dates, appeal deadlines, and supporting correspondence is therefore advisable.
Article
The Polish Supreme Administrative Court, or NSA, has reportedly clarified the scope of judicial review where a tax authority adopts several consecutive decisions extending the deadline for payment of the same VAT refund. Under resolution I FPS 2/26, an administrative court is generally expected to assess the legality of the particular extension challenged by the taxpayer. It should not use that proceeding to carry out a full review of earlier extension decisions that were allowed to become final.
The conclusion is procedurally significant because Polish tax authorities may extend a VAT-refund verification process more than once. Each extension effectively preserves the authority’s ability to continue reviewing the refund claim instead of paying the amount by the previously applicable deadline. According to the press coverage, a taxpayer’s failure to challenge one of those decisions can have lasting consequences for later proceedings.
The reported resolution does not appear to make earlier extensions entirely immune from scrutiny. A court may still need to determine whether the authority had a valid deadline available to extend. In particular, an earlier extension issued or effectively communicated only after the existing refund period had expired may be incapable of extending that period. This distinction is consistent with the separate Poznań administrative court report that even a one-day delay may prevent a valid extension.
For businesses, the principal issue is cash flow as well as legal process. Polish VAT-refund reviews can involve substantial amounts, particularly for exporters, manufacturers, investment projects, and entities operating in a recurring input VAT position. If every extension is legally distinct, local tax teams cannot safely defer their assessment until the authority’s final extension or until the underlying verification has ended.
A practical control should record the original statutory refund deadline, every extension decision, the date and method of service, the new deadline stated by the authority, and the deadline for filing a complaint. The business should also retain evidence showing when electronic correspondence became available and when it was legally deemed delivered.
The resolution should be reviewed against the complete written reasons once published. For now, the prudent approach is to assess each extension immediately and document the business decision whether to challenge it. This is particularly important where the amount is material, the authority’s explanation is generic, or the decision appears to have been issued close to or after expiry of the existing deadline.
