According to Federal Tax Service (FTS) statistics, over 75% of field tax audits result in additional assessments exceeding RUB 10 million. Challenging the act is not a mere formality, but the sole procedural mechanism to reduce the tax deficiency before the decision enters into force (Article 101 of the Russian Tax Code).
How is the audit report delivered and how are procedural deadlines calculated?
The delivery of a tax audit report triggers a strict procedural timeline. Within two months after the certificate of completion of a field tax audit (or ten days for a desk audit), the inspectorate is obliged to draw up the report in the form approved by the FTS under Article 100 of the Tax Code. The document is delivered to the company director against a receipt or sent via telecommunication channels (TCS).
A common error involves miscalculating the start date of the defense period. If the tax authority sends the act by registered mail, the date of receipt is deemed to be the sixth day from the date of dispatch (Paragraph 5, Article 100 of the Russian Tax Code). The taxpayer has exactly 1 month from the date of receiving the act to prepare and file written objections (Paragraph 6, Article 100 of the Russian Tax Code).
Practice indicates that missing this one-month deadline critically diminishes the chances of successfully dismissing the claims. In the absence of written objections, the head of the inspectorate will review the audit materials solely through the lens of the inspecting officers' arguments, which in 99% of cases leads to maximum additional assessments.
How should written objections to the audit report be drafted under Article 100 of the Tax Code?
Drafting objections to the audit report is the stage where the taxpayer formulates the primary line of defence. Objections are filed with the same inspectorate that conducted the audit. It is possible to challenge the act in its entirety or its individual episodes, such as transactions with specific counterparties.
A critical juncture: whether to attach primary documents and counter-calculations immediately. According to Paragraph 29 of the Resolution of the Plenum of the Supreme Arbitrazh Court of the Russian Federation No. 57 dated July 30, 2013, submitting evidence at the objection stage is a right, not an obligation. However, arbitrazh court practice in 2024–2026 leans toward procedural estoppel: courts refuse to admit new evidence if the taxpayer intentionally withheld it from the inspectorate during the pre-trial stage.
The objections must be accompanied by certified copies of documents confirming the reality of the transactions, expert opinions, or independent audit results. The documents are submitted to the tax inspectorate's registry with an inventory of enclosures and an acceptance mark.
Review of Audit Materials and Additional Control Measures
The head of the tax inspectorate is obliged to review the act and objections within 10 days; this period may be extended up to 1 month (Paragraph 1, Article 101 of the Russian Tax Code). The taxpayer must be duly notified of the time and place of the review. Violation of the right to participate in the review process constitutes unconditional grounds for canceling the final decision (Paragraph 14, Article 101 of the Russian Tax Code).
Often, instead of issuing a decision, the tax authority orders additional control measures. Their duration cannot exceed one month under Paragraph 6 of Article 101 of the Tax Code. During this period, the inspectorate is entitled to interrogate witnesses, request documents, and commission expert examinations.
Upon completion of the additional measures, the inspectorate draws up an addendum to the tax audit act. The law grants the taxpayer 15 working days to file objections to this addendum (Paragraph 6.2, Article 101 of the Russian Tax Code). Only after this is the final decision issued, either holding the taxpayer liable or refusing to do so.
Appellate Review by the Higher Tax Authority
If the audit decision contains additional assessments, the rule of mandatory pre-trial appeal comes into effect. The taxpayer files an appellate complaint with the higher tax authority — the Regional Tax Office (UFNS). The filing deadline is 1 month from the date of delivery of the inspectorate's decision (Paragraph 2, Article 139.1 of the Russian Tax Code).
A procedural detail: the complaint is not sent directly to the regional office, but rather through the tax inspectorate that issued the decision. The inspectorate is obliged to forward the complaint along with all audit materials to the higher authority within 3 days (Paragraph 1, Article 139.1 of the Russian Tax Code).
Filing an appellate complaint suspends entry into force of the audit decision. Until the UFNS issues its decision, the tax inspectorate has no right to issue collection orders, debit funds from accounts, or apply enforcement measures under Article 46 of the Russian Tax Code (Paragraph 9, Article 101 of the Russian Tax Code).
How is the audit decision challenged in the arbitrazh court?
Once the UFNS upholds the decision, it enters into legal force. From this moment, the taxpayer gains the right to challenge the non-normative legal act in an arbitrazh court under the rules of Chapter 24 of the Russian Arbitrazh Procedure Code. The deadline for applying to the court is 3 months from the moment the organization became aware of the violation of its rights (Part 4, Article 198 of the Russian Arbitrazh Procedure Code).
The state fee for filing a petition to invalidate the decision for legal entities in 2026 is RUB 3,000 (Subparagraph 3, Paragraph 1, Article 333.21 of the Russian Tax Code). The petition is filed with the arbitrazh court of the constituent entity of the Russian Federation at the location of the tax authority.
A critical risk lies here: filing a petition with the court does not automatically suspend collection of the tax deficiency. Recent practice demonstrates the necessity of simultaneously filing a motion for interim measures suspending the decision's execution under Article 90 of the Arbitrazh Procedure Code. To satisfy the motion, the court generally requires counter-security in the form of a bank guarantee or surety.
What criminal liability risks arise under Article 199 of the Criminal Code?
Challenging the act and decision of the tax authority has a direct impact on the criminal liability risks of controlling persons. The threshold for criminal liability for tax evasion by an organization (Part 1, Article 199 of the RCC) is RUB 35,000,000 in tax deficiency for a period within three consecutive financial years.
If the taxpayer fails to pay the assessed amounts within 75 days after the decision enters into force, the tax authority is obliged to forward the materials to the Investigative Committee (IC) to resolve the issue of initiating a criminal case (Paragraph 3, Article 32 of the Russian Tax Code).
Delaying the decision's entry into force through the filing of an appellate complaint and subsequent court challenges provides the business with necessary time. This period is utilized to accumulate funds to settle the deficiency, which exempts from criminal liability under the note to Article 199 of the RCC, or to prepare an evidentiary base for the defense of the beneficiaries and the director.
Frequently Asked Questions
May the appellate complaint stage at the UFNS be skipped to proceed directly to court?
No. Under Article 138(2) of the Tax Code, judicial review is available only after the mandatory pre-trial procedure has been observed. The arbitrazh court will return the petition under Article 129(1)(5) of the Arbitrazh Procedure Code.
What is the deadline for filing objections to a field tax audit report?
One month from the date the taxpayer receives the report under Article 100(6) of the Tax Code. For reports following additional control measures, the deadline is fifteen working days under Article 101(6.2).
Does filing a petition with the arbitrazh court suspend tax collection?
Filing a petition with the court does not, of itself, suspend collection. The taxpayer must file a separate motion for interim measures under Article 199(3) of the Arbitrazh Procedure Code and demonstrate the risk of significant damage to the business; the court generally requires counter-security in the form of a bank guarantee or surety.
Is the tax audit report itself susceptible to direct judicial challenge?
No. The audit report records the inspector's position and is not itself a non-normative legal act. What is challenged in the arbitrazh court is the final decision on holding the taxpayer liable, issued under Article 101 of the Tax Code.
When does the audit decision enter into legal force?
Under Article 101(9) of the Tax Code, the decision enters into legal force one month after delivery to the taxpayer, unless an appellate complaint is filed within that period. The appellate complaint suspends entry into force; the decision takes effect on adoption of the determination by the higher tax authority, fully or in part as upheld.
What happens if objections are not filed within the statutory deadline?
In the absence of written objections, the head of the inspectorate reviews the audit materials solely on the basis of the inspectors' arguments, which in practice almost always leads to maximum additional assessments. Pre-trial estoppel doctrine in 2024–2026 arbitrazh practice may also restrict admission of new evidence at the judicial stage.
What is the deadline for judicial appeal of the audit decision?
Three months from the moment the organisation became aware of the violation of its rights, under Article 198(4) of the Arbitrazh Procedure Code. The state duty for filing the petition to invalidate a non-normative legal act for legal entities in 2026 is RUB 3,000 under Article 333.21(1)(3) of the Tax Code.
What procedural violations may serve as unconditional grounds to cancel the decision?
Under Article 101(14) of the Tax Code, material violations of the materials-review procedure are unconditional grounds for cancellation. The principal example is failure to ensure the taxpayer's opportunity to participate in the review of audit materials, including failure to give due notice of the time and place of the review.
When is there a risk of materials being forwarded to the Investigative Committee under Article 199 of the Criminal Code?
Where the taxpayer fails to pay the assessed amounts within seventy-five days after the decision enters into force, the tax authority is obliged to forward the materials to the Investigative Committee to consider initiating criminal proceedings under Article 32(3) of the Tax Code. The criminal threshold under Part 1 of Article 199 of the Criminal Code is RUB 18.75 million in tax arrears over three consecutive financial years (raised by Federal Law No. 79-FZ of 6 April 2024); previously the threshold was RUB 35 million.
Conclusion
Challenging the results of a tax audit requires strict adherence to procedural deadlines and the sequence of actions. High-quality written objections prepared at the stage of Article 100 of the Russian Tax Code form the evidentiary foundation for the successful defense of assets in an arbitrazh court.
