- From February 1, 2026, new JPK VAT forms (JPK V7M and JPK V7K) will be introduced, adapted to the KSeF (National e-Invoice System) and the deposit system.
- The changes require including the KSeF invoice number in JPK VAT records and introduce new designations: OFF (invoice without KSeF number), BFK (electronic or paper invoice), and DI (other documents).
- The new regulations do not require correcting sales/purchase records to add KSeF numbers if they were unavailable at the time of submission.
- Updated JPK VAT structures will be available on ePUAP.
- The changes result from amendments to the VAT Act and related regulations signed in December 2025.
