- Poland will mandate B2B e-invoicing through the KSeF platform starting in 2026.
- The mandate will be implemented in two phases: February 1, 2026, for companies with turnover over PLN 200 million, and April 1, 2026, for all other VAT-registered businesses.
- The mandate affects all VAT-registered businesses in Poland, including foreign entities with a fixed establishment.
- B2C transactions are not required to use KSeF, and paper or PDF formats will still be allowed for consumer invoices.
- Businesses should understand technical requirements, plan for integration and testing, adapt invoicing processes, and engage with service providers to ensure compliance.
