- Poland’s e-Invoicing implementation is being gradually implemented in three phases: testing, voluntary, and mandatory.
- B2B e-Invoicing will be mandatory for all VAT-registered taxpayers in Poland, including inter-community and cross-border transactions, by July 2024.
- Taxpayers who participate in the voluntary period will receive benefits such as faster VAT refunds and simplified tax and reporting obligations.
- The required format for e-Invoices is XML, and a KSeF number will be assigned by the tax authority for validation.
- Authentication can be done using digital signature, trusted signature, digital seal, or authorization token.
- Invoices from cash registers can be issued in their current form until December 31, 2024, and consumer invoices (B2C) will not be covered by KSeF.
- Corrected invoices must contain a reference KSeF invoice number.
