Common Reasons for Blocking VAT Invoices

The electronic VAT administration system provides for automatic control over the registration of VAT invoices. Businesses often face situations where the State Tax Service blocks invoices, creating risks of losing VAT credit for counterparties and causing financial and reputational consequences. In this article, we will examine why this happens and how businesses can prevent it.

Why Are VAT Invoices Blocked?

The grounds for suspending VAT invoice registration are defined by Resolution of the Cabinet of Ministers of Ukraine No. 1165 dated December 11, 2019 (as amended). The tax authorities analyze the taxpayer’s activities and transactions for compliance with specific risk criteria.

The Most Common Reasons for Blocking

1. Supply of Risky Goods or Services

If an invoice contains goods or services included in the list of risky categories or sectors frequently associated with tax abuse, the invoice may be automatically suspended.

2. Insufficient Tax History of the Taxpayer

Newly established companies without substantial business activity or with low turnover often fall into the “risk zone” due to the absence of confirmed turnover, personnel, or fixed assets.

3. Mismatch Between Transaction Volumes and Business Capacity

If a company reports large supply volumes while having minimal expenses or lacking sufficient staff, equipment, or warehouse facilities, the system may treat such invoices as suspicious.

4. Counterparty Classified as a Risky Taxpayer

Even if your business operates lawfully, invoices may still be blocked if your counterparty is included in the list of risky entities according to the criteria of the State Tax Service.

5. Errors or Unusual Data in the Invoice

Formal inaccuracies in details, units of measurement, UCGFEA codes, or incorrect dates may also trigger suspension of registration.

What Should Be Done if an Invoice Is Blocked?

• Obtain the suspension receipt, which must indicate the reasons for blocking.
• Prepare explanations and supporting documents (contracts, acts, supplier invoices, payment confirmations, etc.) proving the reality of the transaction.
• Submit the documents through the taxpayer’s electronic cabinet.
• If necessary, appeal the decision of the State Tax Service commission administratively or in court.

How to Avoid Blocking?

• Regularly monitor your status in the system and lists of risky transactions.
• Maintain detailed and transparent accounting records.
• Establish proper document flow with counterparties and verify their reputation.
• Use professional legal support for drafting contracts, preparing primary documentation, and communicating with tax authorities.

Blocking VAT invoices is not always evidence of a violation. In many cases, it is the result of automated algorithms or excessive caution by tax authorities. However, delayed response may lead to the loss of VAT credit and conflicts with business partners.
