- Poland will implement mandatory B2B eInvoicing via the National eInvoicing System (KSeF) and updated VAT return schemas starting February 2026.
- New VAT return structures (JPK_V7M(3) for monthly, JPK_V7K(3) for quarterly) will replace current schemas, introducing new data fields for better traceability.
- Large taxpayers must use KSeF from 1 February 2026; medium and small taxpayers from 1 April 2026; all taxpayers (including foreign entities) from 1 January 2027, with some exemptions.
- VAT deduction will only be possible for invoices received through KSeF, and businesses must update their ERP/accounting systems to comply.
- Certain transactions and services (e.g., tickets, financial services, self-invoicing without Polish NIP) are exempt from mandatory eInvoicing.
