The most important information about tax practices in 1.5 minutes from Ilya Rusyaev
How to protect the company from additional tax charges and penalties of the FTS?
According to FTS data for 2022, 98% of audits result in additional tax charges, with an average amount of 50 000 000 rubles ($ 660 000). If a company attracts the close attention of tax authorities, there is a very high probability of a field tax audit (FTA).
In essence, a FTA is the final stage preceded by several months of active work: analysis of the company's business and financial activities, contractors, counterparties, checking the company in all databases available, studying documents, and other information accessible for the FTS . The likelihood of avoiding penalties and additional charges in this case approaches zero.
Tax check-up — identification of current and deferred tax risks in a company.
Tax due diligence — the analysis of tax risks: studying counterparties, transactions, circumstances, documents to understand the actual situation. The goal is to anticipate the decision of the court on transactions with counterparties and choose optimal behaviour during a tax audit.
Support during FTA — protection of company's interests and employees during a field tax audit.
Tax disputes — defending your rights in the arbitration court if you are dissatisfied with the results of a tax audit.
To reduce tax risks and minimise the consequences of an audit, 3 procedures are available:
When is a tax due diligence necessary?
Planned or scheduled audit
If an audit is expected, it means that the pre-check analysis department is actively working on your company. It is important not to waste time and be prepared.
Bringing order to tax accounting
Tax risks have been identified during the tax check-up, or the financial director or accountant has changed. It is necessary to organise the accounting and reduce tax risks.
Investments or business acquisition
It is necessary to identify the actual tax obligations and potential tax risks of the company in order to protect your investments or facilitate a business acquisition deal.
Tax due diligence for the protection of the company from tax claims, penalties, and additional charges
We analyse counterparties using certain databases and our own methods
We examine documents to identify unjustified tax benefits
We assess the likelihood of an unplanned tax audit, additional tax charges, and penalties
We structure the deals, gather evidence, and minimise tax consequences
We evaluate your company's activities and tax risks from the perspective of the Federal Tax Service (FTS). The tax due diligence is conducted by a team of lawyers and tax consultants, including former employees of the FTS and the judicial system. We know how tax and judicial authorities apply legal norms and how to create reliable protection in your situation.

The result of due diligence is an understanding of the court's likely decision on your company's dispute with the FTS for each specific deal, taking all the circumstances into account. It also involves choosing a strategy for behaviour when additional tax charges are imposed, and minimising tax consequences by structuring the deals and collecting evidence.
We have been protecting the interests of businesses in tax disputes for over 17 years. Depending on the circumstances, we develop a strategy that allows you to resolve the issue with minimal costs.

Cost and conditions of tax due diligence
Tax due diligence provides a judicial perspective: the level of risk involved in your disputes with the FTS on each deal and your chances for success. It helps determine the strategy for dealing with the FTS during the audit — whether it is worth defending your position on a specific deal or it is better to seek a resolution with tax representatives.

The due diligence includes:
In-depth analysis of counterparties: from gathering general information to checking in specialised databases.
Close cooperation with your accounting department, contract analysis, and examination of evidence.
Conclusions on the actuality of business operations with certain counterparties.
Identification and justification of reasonable business objectives in relationships with counterparties.
Evaluation of the counterparty's ability to fulfil obligations under the deal.

It also includes conclusions on risks and the amounts of additional tax charges for specific transactions, with the data recorded in a table of amounts and risks of additional charges.
