Poland is one of the EU countries that introduces central clearance model following the footsteps of Italy. In this context, the Polish government has introduced a centralized platform called “PEF” (Platforma Elektronikznego Fakturowania) for the implementation of the B2G invoicing in April 2019, and another platform “KSeF” (Krajowy System e-Faktur) for the implementation of B2B and B2C invoicing in October 2021.

The mandatory transition to e-invoicing in B2G billing has already been completed in 2019. On the other hand, transition to B2B e-invoicing will be mandatory from 1 January 2024.

Poland takes gradual steps to ensure that the transition to the new regime and the adaptation of the tax payers would be smooth. To that end, the government first introduced the test phase in October 2021 and have started to implement voluntary e-invoicing model, where the acceptance of recipient is required, as of January 2022.

European Commission has approved the request of the Polish government authorizing to implement an obligation to issue electronic invoices, processed through The National System of e-Invoices (KSeF) on 30 March 2022. With the approval of the Commission, this July it was decided that Poland will make the transition to mandatory e-invoicing from January 1, 2024.

The scope of obligation is limited to taxable persons established in the territory of Poland for all transactions that require the issuance of an invoice according to Polish VAT legislation.

The motivation of the government for the introduction of this obligation is to facilitate VAT collection, combat with VAT fraud and accelerate the public digitalization. The new system will also have benefits to tax payers such as ability to see the invoice status, archiving the invoices safer and cheaper as well as increasing the automation of business processes and simplifying compliance with tax obligations. Government also encourages transitions by accelerating VAT refunds, shortening the time interval from 60 days to 40 and exempting the companies to submit JPK_FA files.
