- Poland has amended JPK_VAT requirements to align with the mandatory KSeF 2.0 framework, effective for filing periods starting 1 February 2026.
- Taxpayers must report KSeF invoice numbers or use specific markers (OFF, BFK, DI) in JPK_VAT sales and purchase records, depending on the invoice status.
- Corrections to add KSeF numbers are generally not required, except for certain sales invoices issued offline that later receive a KSeF number.
- Correction rules remain unchanged; errors can be corrected after identification or tax office request, with penalties assessed case-by-case.
- Businesses must update their systems to comply with the new requirements by the February 2026 deadline.
