On 11 October 2026, the Supreme Administrative Court (NSA) ruled that administrative courts lack jurisdiction to review decisions extending VAT refund deadlines if those decisions were not individually challenged by the taxpayer within the prescribed appeal period. The case concerned a series of successive extensions by the tax authority; the taxpayer argued the extensions were unlawful but had not appealed each one. The NSA held that each extension decision is a separate administrative act that must be challenged individually; failure to do so renders it final and binding, precluding later judicial review of its legality.
Key Takeaways
- Mandatory Individual Appeals: Taxpayers must appeal each decision extending the VAT refund deadline separately; a blanket challenge to the final decision is insufficient.
- Finality of Unchallenged Decisions: Unappealed extensions become final, and courts cannot examine their legality retroactively.
- Procedural Vigilance Essential: Businesses must monitor the timeline of refund proceedings closely and file timely appeals to preserve their rights.
