Legal requirement: Under Czech VAT Act §109, if a Czech VAT payer supplier is declared unreliable, the recipient of the taxable supply must verify that payment is made to a registered account. Failure to do so may result in joint liability for the supplier's unpaid VAT.

What is an Unreliable VAT Payer?

The Czech Financial Administration (Finanční správa / MFCR) maintains a public list of VAT-registered companies that have seriously failed to meet their tax obligations. These companies are declared nespolehlivý plátce (unreliable payer).

Once a company is on this list, any of their VAT payers customers who pays them without checking their registered accounts takes on the risk of joint VAT liability. This applies even if the customer had no knowledge of the supplier's tax non-compliance.

When does this matter?

  • Before paying invoices from Czech VAT-registered suppliers
  • During supplier onboarding and due diligence
  • When processing large or unusual payments
  • During period-end closing processes
  • For import/export workflows with Czech companies

What happens if the payer is unreliable?

If you pay a Czech supplier who is declared unreliable and you pay to an account that is not in the official registry, the Czech tax authority may hold you jointly liable for the unpaid VAT on that invoice. This is why both checks — unreliable payer status and bank account registry check — should be done simultaneously.

Use the IBAN & Bank Account Checker to verify the receiving account at the same time.
