Few days ago, the Sejm passed a bill introducing a mandatory National e-Invoice System (KSeF) for taxpayers in Poland. The law will be implemented in stages beginning in 2026.
Implementation Timeline:
· February 1, 2026: Large businesses with over PLN 200 million in 2024 sales must begin using e-invoices.
· April 1, 2026: All remaining entrepreneurs are required to comply.
· January 1, 2027: Small businesses with monthly sales up to PLN 10,000 will join.
Until the end of 2026, businesses can continue using traditional cash registers for invoicing. Penalties for invoicing errors and mandatory KSeF reference numbers in bank transfers will also be delayed during this phase. One of the key features of the new bill is a faster VAT refund process. The standard deadline will be reduced from 60 days to 40 days, helping companies manage their cash flow more efficiently.
