- The smallest VAT taxpayers must start issuing structured invoices via KSeF from January 1, 2027, with no transitional period.
- Penalties for not using KSeF will apply to all entrepreneurs from that same date.
- The Ministry of Finance will disable the test and pre-production environments for KSeF from February 1, leaving only the production environment, which does not allow for testing.
- Smallest taxpayers (those issuing invoices up to 10,000 PLN monthly) will be at a disadvantage compared to larger businesses, who have up to 11 months to adapt.
