VAT ID Validator

Effective VAT risk management

ASB Poland IT team has created a unique IT tool for verifying VAT numbers of both Polish and foreign contractors. VAT ID Validator quickly carries out the verification and generates VAT status confirmations, so you can confirm the status of the contractor at any time. Due to new regulations, our tool has been improved by the function of bulk verification of contractors' bank accounts. In addition, the program has an option to generate automatically a ready-to-send notification to the tax office which state not configuring of the contractor's bank account on the taxpayer's "white list".

Due to the entry into force of the provisions on the transfer of JPK files, the tax risk that may arise from transactions with entities that are not registered for VAT increased significantly. It may complicate regular verification of the VAT status of companies` contractors. Moreover, to avoid any unpleasant surprises, taxpayers will need to check each counterparty’s bank account number in the “white list” register. Payment of an invoice exceeding PLN 15,000 to an account number different than the one included in the register will result in joint and several liabilities for the payer in the field of VAT and loss of the right to settle the tax-deductible expenses in the remaining scope.

Why verification of the VAT numbers of your contractors is important?

Due to the introduction of compulsory monthly reporting in the JPK_VAT format, the risk of finding and challenging tax authorities of transactions with non-registered entities as active VAT payers increased significantly. Currently, many taxpayers spend a lot of time each month by manually checking the VAT status of their contractors.

The status of Polish taxpayers can be verified in the Ministry of Finance database, while the status of VAT taxpayers registered for intra-community transactions in the VIES database. With a large number of contractors this process can be laborious since changes in the VAT status of contractors should be carried out continuously, at least once a month, before submitting the VAT declaration and sending JPK_VAT. Verification of the VAT status of contractors at the beginning of cooperation and establishing a client in the accounting system is insufficient, because the taxpayer can be deregistered from VAT (at the request of a state office) without informing your company.

What are the tax risks of neglecting monthly VAT verification?

Without the continuous verification of the VAT status of contractors Companies are exposed to VAT tax risk, i.e. when purchasing from domestic contractors in the event of the contractor losing the status of an active VAT taxpayer, the company loses the right to deduct VAT from an invoice issued by such a contractor from another EU country, the Company has no right to apply a 0% VAT rate. The lack of proper verification procedures may lead to tax arrears, VAT and criminal penal sanctions. Please remember that according to the regulations, the companies have no right to deduct VAT from an invoice issued by inactive VAT taxpayer (Article 88 (4) of the VAT Act), and also that the 0% VAT rate for WDT can be used provided that the delivery was made to a VAT taxpayer from another EU country with a valid VAT number with the prefix of the EU country of the buyer's country.

Why verification of the bank account numbers of your contractors is important?

From September 2019, the so-called "White list" - a new electronic register of entrepreneurs - VAT taxpayers, will apply. It will include, among others, information on registration, deregistration and taxpayer status, as well as current bank account numbers related to business activity. However, the most important element of the "white list" is the register of bank accounts. Payment of an invoice exceeding PLN 15,000 to an account number different than the one included in the register will result in joint and several liabilities for the payer in the field of VAT and loss of the right to settle the tax-deductible expenses in the remaining scope. To avoid any unpleasant surprises, taxpayers will need to check each counterparty’s bank account number in the register.
