Protection of Taxpayer Rights in Case of VAT Invoice Blocking

In Ukraine’s modern tax system, electronic verification and blocking of VAT invoices have become tools for monitoring business activities. However, these mechanisms are often applied without sufficient grounds, violating taxpayers’ rights and creating risks for the normal operation of businesses.

When Does the Tax Authority Block a VAT Invoice?

The registration of a VAT invoice may be suspended within the VAT Electronic Administration System if it falls under the risk criteria established by Resolution of the Cabinet of Ministers of Ukraine No. 1165 dated December 11, 2019. The most common grounds for blocking are:

• the counterparty is classified as “risky”;
• insufficient tax history of the company;
• suspicious transaction volumes that do not correspond to the company’s assets or personnel;
• technical errors or unusual data in the invoice;
• supply of “risky” goods or services.

How Can a Taxpayer Protect Their Rights?

1. Administrative Appeal Procedure

The first step is to submit explanations and supporting documents to the tax authority through the electronic taxpayer cabinet. Such documents include:

• contracts with counterparties;
• acts of completed works or services;
• transportation documents;
• bank payment confirmations;
• supplier VAT invoices, etc.

The tax commission reviews the submitted materials and decides whether to register the invoice or refuse registration. In case of a repeated refusal, the taxpayer has the right to file an administrative appeal with the higher tax authority within 10 business days from receiving the decision.

2. Judicial Appeal Procedure

If the administrative appeal does not produce a positive result, or if the taxpayer considers the tax authority’s decision unlawful, it is possible to file a lawsuit in court. Ukrainian administrative courts have repeatedly ruled in favor of taxpayers, recognizing decisions on VAT invoice blocking as illegal.

Court proceedings require a clearly structured legal position, evidence confirming the reality of business transactions, and proper legal representation.

Practical Recommendations

• Maintain systematic documentary support for all transactions — this is the best protection against unjustified blocking.
• Regularly check the status and tax history of counterparties.
• Do not delay submitting explanations and administrative appeals.
• Involve lawyers at the stage of drafting contracts and invoices to avoid formal mistakes.
