Why Verify Bank Accounts?

Under Czech VAT law (§109 ZDPH), if you pay a Czech VAT payer and the payment goes to an account that is not published in the official registry, you may be jointly liable for their unpaid VAT.

This is especially critical when paying an unreliable VAT payer (Czech: nespolehlivý plátce). In that case, verifying the receiving account is a legal obligation.

This tool checks both conditions simultaneously: whether the supplier is an unreliable payer, and whether the bank account you're paying to is in the Czech Tax Authority (MFCR) registry.

How to Use

  1. Enter the Czech VAT number (DIČ) of the company
  2. Enter the account number and bank code, or the IBAN, or both
  3. Click "Verify Accounts" — results appear in real time
  4. For bulk verification, use the XLSX import (download the template first)
Note: This tool only supports Czech VAT entities. Foreign IBANs (non-CZ) are checked but always return a warning, as they cannot be verified against the Czech registry.
