Unblocking VAT Invoices

Unblocking VAT invoices is legal support for a VAT payer when the registration of a VAT invoice or adjustment calculation is suspended in the Unified Register of VAT Invoices. For a business, this is often not just a technical delay, but a risk of conflict with the counterparty, loss of VAT credit for the buyer, cash flow pressure, disrupted supplies, and accumulation of new tax risks.

A VINCO’S attorney helps analyze the suspension receipt, identify the reason for blocking, prepare written explanations, form the set of primary documents, file the notification with the tax authority, support the review process and, if necessary, challenge the refusal administratively or in court.

The purpose of support is not simply to file a standard set of documents, but to prove the reality of the business transaction, the logic of the taxpayer’s activity, the availability of resources for the supply of goods or services, and the absence of grounds for refusing VAT invoice registration.

VAT invoice blocking means that automated monitoring has suspended registration in the register after checking the taxpayer or transaction against established risk criteria. Usually, the taxpayer receives a receipt stating the reason for suspension and proposing to submit explanations and copies of documents.

In practice, the reasons may vary: taxpayer risk status, transaction risk, mismatch between purchased and supplied goods, absence of a taxpayer data table, insufficient supporting documents, transactions with risky counterparties, or formal mistakes in the invoice.

After registration is suspended, the taxpayer may submit written explanations and copies of documents confirming the information stated in the VAT invoice or adjustment calculation. If the regional commission refuses registration, the decision may be challenged.

• receipt suspending registration of the VAT invoice or adjustment calculation;
• the VAT invoice or adjustment calculation whose registration was suspended;
• contract with the counterparty, annexes, specifications, orders, invoices and commercial documents;
• service completion acts, delivery notes, waybills, acceptance-transfer acts;
• payment orders, bank statements and settlement documents;
• documents on origin, purchase, production, storage or transportation of goods;
• documents on employees, equipment, warehouse, office, transport, licenses or other resources;
• tax and financial reporting confirming real business activity;
• previous explanations, notifications, tax decisions or complaints, if already filed;
• information on the buyer, supplier, supply chain and economic substance of the transaction.

In many cases, unblocking one invoice does not fully solve the problem if the business faces repeated blocking. Then it is necessary to analyze not only the specific transaction but also the taxpayer’s profile: activity codes, product and service nomenclature, balances, employees, fixed assets, counterparties, and the business logic.

The VAT taxpayer data table may help explain to the tax authority the goods, services and activities typical for the business. However, a formal table without a quality explanation and supporting evidence often leads to refusal. It is important to prepare not only the table, but also a description of activity and documents regarding resources, contracts, supplies, production or services.

If the taxpayer is included in the risky taxpayer list, documents for a single invoice may be insufficient. In that case, VINCO’S prepares a separate position for removal from the risky list and confirmation of the company’s actual business activity as a whole.

If the regional commission refuses registration after explanations are submitted, the taxpayer may challenge such decision. It is important to quickly assess whether an administrative complaint is reasonable or whether a court claim should be prepared immediately.

Administrative appeal may be effective where the refusal is clearly formal or the documents were incomplete. Court appeal is appropriate where the tax authority ignores the reality of the transaction, refers generally to insufficient documents, fails to specify violations or adopts an unreasoned decision.

In court, the attorney builds the legal position, proves the reality of the transaction, demonstrates procedural violations and requests the court to cancel the refusal and oblige the tax authority to register the VAT invoice or adjustment calculation.

Self-managed unblocking often means uploading as many documents as possible without a clear logic. This approach may not help and can create additional risks if the documents contradict each other, fail to explain the transaction, or contain mistakes.

• filing an incomplete or chaotic document package;
• absence of a clear explanation of the business transaction;
• mistakes in contracts, acts, delivery notes, waybills or payment documents;
• mismatch between activity codes, nomenclature and actual activity;
• ignoring risky taxpayer or risky counterparty status;
• missing deadlines for explanations or appeals;
• refusal due to formal deficiencies;
• weakening the future court position due to poor initial submissions.
