What is tax consulting and who needs it?

Tax consulting is a comprehensive assistance in resolving issues related to taxation of businesses and individuals. It includes tax risk analysis, optimization of financial flows, preparation of reporting and development of strategies that comply with current legislation.
Who is this service suitable for:
  • owners of small, medium and large businesses;
  • enterprises working with foreign partners;
  • companies planning investments, M&A or entering new markets;
  • entrepreneurs who want to avoid fines and inspections.

In what cases are tax planning services needed?

Tax planning is the process of optimizing the tax burden before any obligations to the budget arise.
The service is relevant:
  • when opening a new business or changing its form;
  • during international transactions and working with non-residents;
  • to reduce tax expenses within the limits of the law;
  • when developing a strategy for investors or going on an IPO.
  • Proper planning helps to avoid financial risks and improve business profitability.

How does a tax audit work and why is it needed?

A tax audit is an independent review of a company's financial and tax documentation for compliance with legal requirements.
Audit stages:
  1. Collection and analysis of documents.
  2. Identification of errors and risks.
  3. Preparation of a report with recommendations.
  4. Support in correcting deficiencies.
Result: reduced likelihood of fines, increased financial transparency and confidence before tax audits.

What is tax Due Diligence?

Tax Due Diligence is an in-depth analysis of a company's tax history before concluding major deals or attracting investments.
It allows:
  • assess tax liabilities and risks;
  • identify hidden debts and possible fines;
  • confirm business transparency for investors and partners.
  • The service is especially important during M&A, raising credit or business restructuring.

How does international tax consulting differ from regular tax consulting?

International tax consulting covers tax rules in multiple jurisdictions, including double taxation agreements and BEPS requirements.
It allows:
  • correctly structure your business in different countries;
  • reduce your tax burden;
  • avoid fines and sanctions when working abroad;
  • effectively plan international financial flows.

How to prepare for a tax audit?

To minimize risks, preparation for the inspection should be systematic:
  • conduct an internal audit of reporting and primary documents;
  • check contracts with counterparties;
  • instruct staff on how to interact with inspectors;
  • prepare a package of responses to potential State Tax Service requests.
Early preparation significantly reduces the risk of fines and additional charges.

What benefits will a business receive from tax consulting?

  • Minimizing risks — avoiding fines and claims from tax authorities.
  • Cost optimization — reducing the tax burden without violating the law.
  • Increasing transparency — strengthening the trust of investors and partners.
  • Support in disputes — protecting interests in tax conflicts.
