Split Payment​

The split payment mechanism in Poland is a unique payment system that involves separating the Value Added Tax (VAT) portion from the total transaction amount, channeling it into a distinct VAT account with restricted access for sellers, and ensuring timely transfers of these VAT funds to the government, while the remaining net amount goes into the seller’s regular settlement account, effectively enhancing tax transparency, compliance, and discouraging fraudulent activities. 

In accordance with art. 108a paragraph 2 of the Act on VAT split payment in practice means the impact of: 

  • All or part of the VAT amount from the invoice to the special VAT account.
  • All or part of the net amount from the invoice to the settlement account or to the SKOK account for which the VAT account is kept or to settle it in another way, e.g., in cash. 


  • Waiver of join and several liability rule.
  • No imposing additional tax liability.

VIES - checking contractor status ​ by tax identification number (PL/EU)

Taxpayers making transactions with domestic contractors can verify the VAT numbers of Polish active VAT taxpayers. Such verification proves to be important, among others for taxpayers using the reverse charge mechanism for goods that are listed in Annex 11 to the VAT Act or who use the so-called “bad debt relief”. 

Performing intra-Community transactions requires confirmation of EU VAT numbers of contractors. The result also allows you to verify the association of the EU VAT number with the company name and address. 


  • Possibility to protect company against any consequences of accepting an invoice from a contractor who has never been or no longer is an active taxpayer.
  • Assurance that contractor is an active VAT taxpayer.

  • Registered as VAT payers, including reinstatement of registration as VAT payers.

The whitelist of taxpayers will contain primarily the bank account numbers of entrepreneurs to which the contractors should make payments (these are the accounts entered in the identification / update declaration NIP or CEIDG). 


  • Simplifies the process of verification and obtain information about other business entities.
  • Simplifies data mining  according to tax number or part of the name of business entity.
  • Assurance that the payment for an invoice will flow to the relevant account  of a contractor (active VAT taxpayer).
  • Time and work saving.
  • All actions done directly from the system.
