- KSeF 2.0, Poland’s National e-Invoicing System, went live on 1 February 2026 for large taxpayers (gross sales over PLN 200 million in 2024).
- KSeF becomes mandatory for all other taxpayers on 1 April 2026, with a further extension to 1 January 2027 for those with low invoice volumes.
- All taxpayers must be able to receive invoices via KSeF from 1 February 2026, even if not yet required to issue them.
- The transition period may be challenging, as invoices may be received both within and outside KSeF; taxpayers may need to seek individual tax rulings to secure VAT recovery.
- New tax explanations clarify when foreign taxpayers with fixed establishments in Poland must use KSeF, but the guidance is general and subject to interpretation.
