- The mandatory KSeF system will be implemented as planned: large companies must issue invoices via KSeF from February 1, 2026, and other businesses from April 1, 2026; only very small businesses can delay until January 2027.
- All businesses, regardless of size, must receive invoices through KSeF starting February 1, 2026.
- Many small and medium-sized businesses, as well as accounting offices, are not ready for KSeF and are calling for a postponement, but the Ministry of Finance refuses to delay the rollout.
- There will be no penalties in 2026 for late or incorrect KSeF implementation, but errors in JPK VAT files will be penalized from February 1, 2026.
- Large companies are mostly prepared, while small businesses lack information and readiness, prompting calls for more education and support.
