- In 2026, significant changes in tax and accounting regulations will take effect in Poland, with the introduction of the National e-Invoice System (KSeF) being the most notable.
- From February 1, 2026, KSeF will be mandatory for companies with sales exceeding 50 million euros in 2024; from April 1, 2026, it will apply to all other businesses.
- KSeF will require all invoices to be issued electronically, impacting not only accountants but also sales, cashiers, and B2B partners.
- The system will eliminate corrective notes and invoice duplicates, introduce new JPK files, and change VAT exemption thresholds.
- Companies are advised to prepare internal access policies and review client contracts to ensure compliance and smooth transition.
