- From 1 February 2026, all Polish taxpayers must report KSeF invoice numbers in their JPK_VAT submissions for both sales and purchases.
- There is no transition period; compliance with both KSeF and updated JPK_VAT reporting is required immediately.
- Special document markings (OFF, BFK, DI) must be used when KSeF numbers are unavailable, with correction obligations if numbers are later assigned.
- The regulation applies to all taxpayers required to use KSeF, regardless of their individual rollout date.
- Businesses should prepare now for these changes, as the regulation is expected to be finalized soon.
