Voluntary tax audit by UHY Prostir: review of tax reporting and accounting before the tax authority's visit. Risk identification, recommendations, 20 years of experience.

What is a voluntary tax audit
A voluntary tax audit is an independent check that taxes are accrued and paid correctly and that tax reporting complies with the law. Unlike a financial audit, which assesses the statements as a whole, it focuses specifically on the company’s tax risks — and unlike a tax audit by the authorities, the company orders it itself, on its own schedule.
When a voluntary tax audit is needed
- Before a scheduled or unscheduled tax audit — to find and fix errors in advance rather than during the tax authority’s visit.
- When the chief accountant or accounting system changes — to check whether reporting was kept correctly until that point.
- Before selling the company or attracting an investor — tax risks affect the deal value.
- After receiving a request or notice from the tax authority — to assess the real scale of potential claims.
- For systematic control — a regular review as part of the company’s overall tax risk management.
What a voluntary tax audit includes
- a check that corporate income tax, VAT and other mandatory payments are calculated correctly;
- analysis of tax reporting against source documents;
- identification of transactions with elevated tax risk;
- recommendations for eliminating the identified discrepancies before the tax authority finds them.
How a voluntary tax audit differs from a financial audit
A financial audit assesses the reliability of the company’s financial statements as a whole and ends with a formal audit opinion. A voluntary tax audit is a narrower review focused on tax risks and the accuracy of settlements with the budget; it complements rather than replaces a financial audit. If you need an audit of financial statements, including a statutory one — that is a separate service with the corresponding opinion.
How much does a voluntary tax audit cost
The cost depends on the volume of the company’s transactions, the number of taxes to be reviewed and the period covered by the review. We provide an exact quote after a short clarification of the initial data.
