Bank Account Verification

The service integrates with the VAT Taxpayers White List (Ministry of Finance API) to verify the bank account numbers of contractors.

What is the White List​

The White List is a public register of VAT taxpayers maintained by the Head of the National Revenue Administration (KAS). It contains, among other things, bank account numbers reported to the tax office.

Automatic Verification​

Bank account verification occurs automatically in two places:

  1. Company Settings — when entering your own company's bank account number.
  2. Contractor Edition — when entering a contractor's bank account number.

Payments exceeding 15,000 PLN to an account not listed on the White List may result in the inability to include the expenditure as a tax-deductible cost and joint liability for VAT.

Data from the White List​

In addition to account verification, the API returns:

  • Full name of the taxpayer
  • VAT status (active / exempt / unregistered)
  • A list of all reported bank accounts
