Product description

Get access to the comprehensive, daily-updated database of VAT taxpayers maintained by the Ministry of Finance.

Our API for the VAT Register allows you to check individual businesses as well as continuously synchronize the entire registry.

We provide data on taxpayer status (active, exempt, deregistered), bank account numbers on the VAT White List, and a history of changes in JSON format, which allows for automatic processing and integration with your IT systems.

We offer the ability to query the VAT Taxpayer Registry in real time, without the limits imposed by the Ministry of Finance’s official API. This allows you to quickly verify even several hundred thousand entities at once.

Use our VAT API to automate the process of verifying business partners and avoid transactions with entities removed from the register, as well as transfers to unverified bank accounts.

For more information, please refer to our API documentation.

What is the VAT Taxpayer Registry?

The VAT Taxpayers List, also known as the “white list of VAT taxpayers,” is an official registry maintained by the National Tax Administration. The purpose of this list is to enhance the security of business transactions and reduce the risk of unwitting involvement in tax fraud.

expand_more More expand_less Less

The VAT Taxpayer Registry contains a range of important data, such as: company name, Tax Identification Number (NIP), REGON number, registered office address, VAT registration status, and bank account numbers reported to the tax office.

This allows businesses to quickly verify whether a business partner is a registered VAT payer and whether they are using the correct bank account.

It is recommended to consult the VAT Register not only when verifying new business partners, but also for every major transaction.

Checking the data before payment helps avoid penalties resulting from so-called “joint and several liability” for VAT not paid by the supplier. Furthermore, proper verification documentation can serve as evidence of due diligence in the event of a tax audit.

Access to the VAT Taxpayer Register is free of charge and available on the Ministry of Finance website or via API integration.

Simply enter your tax ID number, bank account number, or company name to get the latest information. Regularly verifying contractor information has become a standard of good business practice and a key part of minimizing tax risk.
