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.
The MFCR unreliable payer registry is updated in real time — whenever a company is added or removed from the list, the change becomes visible immediately. This tool queries the registry live on every check, so results always reflect the current state.
Yes. A company can be removed from the list once it has remedied the tax non-compliance that led to its listing. The company must apply to the Czech Financial Administration and demonstrate that it has fulfilled its tax obligations.
NENALEZEN means the VAT number was not found in the MFCR registry at all. This typically means the entity is not registered for VAT in the Czech Republic (either not a Czech entity, or not a VAT payer). In this case, the unreliable payer check is not applicable.
