ASK VAT-3: How the Tax Authority's AI Checks Your Business

What ASK VAT-3 Is

ASK VAT-3 (Automated System for Controlling VAT Refunds, third generation) is a Federal Tax Service software platform powered by machine-learning algorithms. The system analyses:

  • VAT returns from all taxpayers in real time,
  • bank statements received through extended tax monitoring,
  • external databases: Rosreestr (land registry), traffic police, director and founder records,
  • phone numbers, IP addresses, and email addresses to identify connections between different legal entities.

Its purpose: automatically detect companies that underreport VAT through chains of “paper” suppliers, business fragmentation, or fictitious transactions.

What the System Flags as Suspicious

Gaps in the VAT Chain

If your supplier declared VAT payable but did not actually pay it, and you claim that VAT as an input credit, the system records a “gap.” Even if you had no knowledge of the supplier’s violations, the tax authority may deny your VAT deduction and assess additional tax.

Signs of Affiliation

ASK VAT-3 looks for hidden links between companies through:

  • shared directors, founders, or registered addresses,
  • identical IP addresses used to file returns,
  • phone numbers registered to the same person,
  • matching bank details or payment patterns.

If the system detects these signals, the companies may be treated as a related group, creating grounds for an audit of the group’s consolidated tax burden.

Atypical Transactions

A sharp increase in VAT credits, large one-off shipments from new counterparties, or a revenue-to-tax-burden ratio that diverges from sector benchmarks — all of these automatically trigger a risk flag.

What to Do If You Land in a Risk Zone

Find out your risk rating. The Federal Tax Service classifies taxpayers into three groups: low, medium, and high risk. The level affects the likelihood of a field audit. You can check your status in the taxpayer’s personal account.

Screen your counterparties. Before major transactions, ask partners for an extract from the State Register of Legal Entities (EGRYUL) and a tax clearance certificate, and verify that they are genuinely operating businesses. Having a counterparty due-diligence file protects you if additional tax is assessed.

Remove obvious signs of affiliation. If several of your companies file returns from the same IP address, that creates a consolidation risk. Separate the IT infrastructure organisationally or switch to different authorised representatives.

Respond to inquiries promptly. A request for explanations or documents relating to a VAT “gap” is not a cause for panic, but it requires a fast and well-crafted response. Silence risks triggering a field audit.

The New Reality of Tax Control

ASK VAT-3 renders traditional optimisation schemes using “paper” companies unworkable: the system sees gaps automatically and generates an audit assignment without any human inspector’s involvement.

Tax planning in 2026 is built not on minimising headline figures, but on the genuine economic substance of transactions and transparency in the supplier chain.
