Comply With E-Invoicing Regulations in Poland
Since 2018, Poland has mandated the receipt and processing of e-invoices for central, regional, and local authorities. Starting in 2026, this requirement will extend to B2B entities. To comply with e-invoicing regulations, Poland has established two distinct systems: the National E-invoicing Platform (PEF) for B2G transactions and the KSeF for B2B transactions. KSeF will go live in 2026. Here are the relevant regulations:
Invoice Archiving
According to the Polish regulations, e-invoices must be archived for a period of up to 5 years.
Transaction reporting
At present, VAT returns can be submitted on paper or electronically. Once KSeF is launched, VAT reporting will transition to an e-invoicing system.
Formats
Polish systems support UBL 2.1 and CII formats to follow the European e-invoicing standard, ensuring EU-wide compatibility.
Both PEF and KSeF align with the Peppol BIS Billing 3.0 format used within the Peppol network.
Send & Receive e-Invoices in Poland
In Poland, central, regional, and local authorities must receive and process e-invoices through PEF. Starting in 2026, B2B entities will need to use KSeF for the same purpose.
The Polish government plans to make sending e-invoices mandatory in 2026.
Companies can streamline the receipt and sending of e-invoices in compliant formats by using e-invoicing software.
