Why verify an account in the VAT White List?

Account verification checks whether a specific account number is assigned to a given tax ID (NIP) in the Register of VAT Payers. It's a key element of due diligence for payments over 15,000 PLN — and your proof that you checked the counterparty (an MF confirmation identifier).

The check runs directly against the Ministry of Finance's API, using the tax ID (NIP) and account number (NRB). Free, no login required.

Frequently asked questions

What are the risks of paying into an account outside the VAT Register?

For transactions over 15,000 PLN, paying into an account outside the Register may mean the expense can't be counted as a tax-deductible cost, plus joint and several liability for the counterparty's VAT. You can limit this risk by filing a ZAW-NR notification within the statutory deadline (currently 7 days).

What is the confirmation identifier (requestId)?

It's a unique number that the Ministry of Finance returns with every check. Keep it — it's proof that you verified the counterparty's account on a given day (due diligence).

Where do I get the counterparty's account numbers?

You'll find every account the entity has reported in the VAT White List tool — just enter the tax ID (NIP).

Is the verification free?

Yes. The query goes directly to the Ministry of Finance's API, is free, and requires no registration. This is general information — consult your accountant for tax-specific details.
