How to Prepare for a Tax Audit Before Receiving the Official Notice

A tax audit represents a significant financial, reputational, and operational risk for any company.

Today, the selection of entities for audit by the Financial Administration increasingly relies on advanced analytical tools, cross-checking of information reported in tax filings, and the identification of deviations within specific industries.

A reactive approach—preparing only after receiving a notice of a tax audit—is insufficient from a risk management perspective. Effective preparation must be systematic and ongoing.

1. Tax Risk Management

Assessing tax risks should form an integral part of a company’s internal control framework. This typically includes:

  • identifying risk areas based on the nature of the business,

  • screening and assessing potentially high-risk business partners,

  • conducting regular internal reviews,

  • clearly defining responsibilities for tax matters,

  • establishing a documented escalation process for identified issues.

The absence of a structured approach increases the likelihood that tax risks remain undetected, potentially resulting in additional tax assessments, penalties, and interest.

2. Areas Most Frequently Subject to Audit

Based on the practical experience of tax authorities, the following areas are most commonly reviewed during tax audits:

  • VAT deductions,

  • transfer pricing,

  • the eligibility and substantiation of tax-deductible expenses.

In these areas, it is not sufficient to demonstrate formal compliance alone. Companies must also be able to demonstrate the economic substance and genuine nature of the underlying transactions.

3. Documentation and Burden of Proof

In tax proceedings, the burden of proof generally rests with the taxpayer. This creates a need for:

  • consistent and well-structured contractual documentation,

  • clear evidence that services or supplies were actually provided (deliverables, reports, correspondence),

  • alignment between accounting records, tax filings, and the economic reality of the transactions,

  • up-to-date transfer pricing documentation.

Transactions that are insufficiently documented or unsupported and failure to meet the burden of proof are among the most common reasons for additional tax assessments.

4. Procedural Readiness for the Audit Process

A tax audit is a formal process governed by statutory deadlines, procedural rules, and significant legal requirements.

Companies should therefore ensure:

  • a designated person responsible for communication with the tax authority,

  • an internal process for providing documents and information,

  • proper records of all documents submitted during the audit,

  • control over the scope and timing of responses.

Inconsistent or uncoordinated communication can lead to an unnecessary expansion of the audit scope or complications in closing the audit process.

5. Professional Representation During a Tax Audit

The involvement of a tax advisor during a tax audit can significantly reduce both procedural and financial risks. Professional assistance typically ensures:

  • coordinated and controlled communication with the tax authority,

  • preparation and review of submitted documentation,

  • formulation of professional tax and legal arguments,

  • protection of the taxpayer’s rights,

  • oversight of the audit process and any related follow-up proceedings.

A tax audit is a formal procedure with clearly defined rules and deadlines. Early involvement of an experienced advisor helps ensure that the company responds accurately, consistently, and in compliance with applicable legislation.

Conclusion

A tax audit should not be viewed as a crisis, but as a manageable process.

Companies that actively manage their tax risks enter an audit well prepared—with supporting documentation, clear arguments, and appropriate internal processes in place.

Prevention is considerably less costly than dispute resolution.
