Invoicing in Poland

Polish invoicing requirements

Under the Polish VAT Act, invoices must be issued in two copies, with one given to the customer. These invoices can be issued at the earliest 30 days before, and no later than 15 days after the month’s end in which the goods or services were provided.

While the invoice can be in any currency, the VAT amount must be specified in Polish Zloty (PLN). Issuing VAT invoices is not obligatory for companies that exclusively deal in VAT-exempt goods or services. Additionally, for sales to non-business private individuals, VAT invoices are not necessary unless specifically requested.

To support a claim for input tax deduction or reimbursement under EU refund schemes, a VAT invoice is essential. Businesses have the flexibility to include extra information on their invoices beyond the basic requirements outlined above.


Electronic Invoicing

Poland has voluntary electronic invoicing under Article 106g of the VAT Act, but is mandatory for B2G transactions under the Act on Electronic Invoicing in Public Procurement.


From January 1, 2022, structured invoices can be issued through the Krajowy System e-Faktur (KSeF) in accordance with Article 106na et seq of the VAT Act. However, as of January 1, 2024, electronic invoicing will be mandatory in Poland, following the publication of Council Implementing Decision 9217/22 by the Council of the European Union.


The KSeF system uses standardized invoice templates, which are populated by the taxpayer through an API and automatically stored in the national system for up to 10 years. To use the system, a taxpayer must be authorized and authenticated with a qualified electronic signature, seal, trusted profile, or KSeF-generated authorization token. The KSeF system assigns an identification number before the invoice can be issued, and the structured invoice is considered issued on the date it is sent to the National e-Invoice System and received on the date the identification number is assigned.
