On 21 September 2026, the Polish Ministry of Finance announced a landmark reform to the tax interpretation system, proposing to limit the validity of individual interpretations issued by the National Tax Information (KIS) to a fixed period of five years. This legislative initiative, expected to be incorporated into the Tax Ordinance, aims to enhance legal certainty and align taxpayer protections with evolving tax law. Currently, individual interpretations remain valid indefinitely unless explicitly revoked, creating a growing body of potentially outdated guidance. The new rules introduce automatic expiration of interpretations that conflict with subsequent legislative changes, court rulings, or official positions, alongside a simplified procedure for taxpayers to request extensions of protection where justified. The verification of interpretation currency will be facilitated through the centralized EUREKA database, which will flag expired or superseded positions. For multinational enterprises and domestic taxpayers alike, this shift necessitates a systematic review of all reliance letters and interpretive positions currently supporting tax positions, particularly in areas such as transfer pricing, VAT exemptions, and CIT reliefs. The Ministry emphasized that the reform responds to concerns about legal uncertainty arising from interpretations based on repealed provisions, and aims to reduce disputes by ensuring that taxpayer protection is anchored in current law. Transitional provisions will allow a grace period for existing interpretations, but taxpayers should immediately inventory their reliance portfolio and assess exposure.
Key Takeaways
- Fixed Five-Year Validity Period: Individual tax interpretations will automatically expire five years after issuance unless extended, ending the era of perpetual reliance on outdated guidance.
- Auto-Expiry for Conflicting Positions: Interpretations contrary to new laws, regulations, or consistent judicial decisions will lapse automatically without formal revocation, accelerating alignment with current law.
- EUREKA Database as Compliance Tool: Taxpayers must monitor the EUREKA database for real-time status of interpretations, integrating this check into periodic tax risk assessments and audit defense preparation.
- Simplified Extension Procedure: A streamlined process will allow taxpayers to apply for validity extensions where the interpretation remains consistent with current law, reducing administrative burden while maintaining protection.
