Poland Taxpayer’s Whitelist;

From September 2019, the so-called white list of VAT in Poland has applied. It contains information on VAT registration, de-registration and status of the Polish VAT payer, as well as bank account numbers of entrepreneurs in Poland. Money transfer to an account other than the one indicated on the Polish VAT white list may be subject to critical consequences for companies in Poland.

Starting from 1 January 2020 taxpayers who make transactions the single value of which exceeds PLN 15,000 or the equivalent amount, regardless of the number of payments, will be obliged to make payments to the payee’s bank account shown on the whitelist.

What data will be available?

The whitelist will include VAT-registered taxpayers, including those whose registration has been restored, those removed from the register or which have been refused registration. The list will include a great deal of details about enterprises:

  • business name or name and surname
  • tax identification number NIP,
  • statistical number REGON,
  • Polish personal identification number PESEL (if available)
  • National Court Register number (if any)
  • address of the registered office or fixed establishment or correspondence address
  • details of individuals – members of the body authorised to represent the entity
  • date of registration, refusal of registration or removal and restoration of registration for VAT
  • legal basis for the registration, refusal of registration or removal from the list of VAT-registered taxpayers
  • numbers of checking accounts specified in the registration or updated registration form
