- Poland’s National e-Invoicing System (KSeF) will become mandatory in phases, starting February 1, 2026, for large taxpayers, and April 1, 2026, for all other taxpayers established or registered for VAT in Poland, with foreign entities without a fixed establishment currently excluded.
- KSeF centralizes B2B invoice exchange in a structured XML format (FA(3)), providing the Ministry of Finance near real-time access to data for faster VAT verification and reduced fraud.
- Businesses must prepare by upgrading IT systems, redesigning internal invoicing processes, registering for KSeF access, training staff, and adapting archiving policies to comply with the new mandatory e-invoicing requirements.
