- Poland is postponing mandatory use of the National E-Invoicing System (KSeF) to fix system flaws.
- Large enterprises must use KSeF from February 1, 2026; other VAT entities from April 1, 2026; micro-entities possibly from January 1, 2027.
- The KSeF IT system will be rebuilt with modular implementation, ongoing testing, and new leadership.
- KSeF mandates structured XML invoices for B2B transactions, bans PDF attachments, and gives tax authorities real-time access.
- Relief for preparation costs and penalties for non-compliance (starting 2027) are being considered.
