On 1 September 2026, the Polish National Revenue Administration (KAS) issued a technical notice informing users of a planned maintenance window for the eUrząd Skarbowy (e-Tax Office) portal. The maintenance is scheduled for 1 September 2026 and may cause temporary disruptions to the availability of electronic tax services. Affected functionalities include submission of tax returns (PIT, CIT, VAT), access to the Twój e-PIT personal tax account, management of powers of attorney, verification of VAT taxpayer status via the White List (Biała Lista), and access to the individual tax micro-account (mikrorachunek podatkowy). The KAS advises all taxpayers, tax advisors, and payroll administrators to plan their activities accordingly and complete any time-sensitive operations before the maintenance begins. Regular maintenance windows are part of the administration’s strategy to ensure the reliability and security of its digital tax administration platform.
Key Takeaways
- Early September Maintenance: The eUrząd Skarbowy portal will be undergoing maintenance on 1 September 2026, potentially limiting access to all core e-services.
- Broad Service Impact: The outage covers tax filing, VAT status checks, power of attorney management, and tax micro-account access, affecting both individual taxpayers and businesses.
- Proactive Planning: Stakeholders should finalize September tax obligations ahead of the maintenance date to avoid compliance risks associated with last-minute filing attempts.
