Why Is Regular Tax Review Important, Even If Your Company Has an Accountant?
News – 13.09.2026

Many businesses assume that if they have a reliable accountant, their tax affairs are “under control.” In reality, however, bookkeeping and a tax review (tax health check) serve different purposes and focus on different aspects of a company’s operations. While bookkeeping concentrates on the statutory recording of business transactions, a tax review examines the company’s tax compliance, risks, and weaknesses from a broader, system-wide perspective.
What Is a Regular Tax Review?
A tax review is a structured, periodic assessment designed to determine whether:
- the company’s tax practices comply with the applicable legislation;
- accounting and administrative processes adequately support tax compliance;
- any hidden tax risks exist; and
- critical decisions and tax positions are appropriately documented.
Important:
👉 A tax review is not an audit of the accountant’s work. Rather, it is an independent, system-level control mechanism.
Why Doesn’t Bookkeeping Replace a Tax Review?
The primary responsibilities of an accountant are:
- processing accounting documents;
- preparing tax returns; and
- fulfilling statutory compliance obligations.
A tax review, by contrast, addresses questions such as:
- whether the applied tax practices are correct;
- whether potentially risky structures exist;
- whether tax positions are applied consistently; and
- whether the available documentation would withstand a tax audit.
For this reason, bookkeeping and tax reviews are not alternatives to one another but complementary elements of tax certainty and risk management.
Why Is It Worth Conducting Tax Reviews Regularly?
✅ Because Taxation Is Not Static
Tax legislation changes, business processes evolve, and new types of transactions emerge. A practice that was previously appropriate may gradually become a tax risk without being noticed..
✅ Because Errors Are Often Systemic
Tax issues rarely arise from a single invoice. More commonly, they result from:
- recurring process deficiencies;
- unclear responsibilities; or
- insufficient documentation.
✅ Because the Hungarian Tax Authority Takes a System-Based Approach
Tax audits are becoming increasingly:
- data-driven;
- process-oriented; and
- focused on multiple tax periods.
A regular tax review helps businesses prepare for this approach and identify weaknesses before they become significant issues.

Situations Where a Tax Review Is Particularly Advisable
🔹 Business Growth or a Change in Business Model
Examples include:
- launching a new business activity;
- entering a new market; or
- experiencing a significant increase in revenue.
Existing tax practices may no longer adequately reflect the company’s new operating model.
🔹 International Expansion or Cross-Border Activities
Examples include:
- foreign ownership;
- cross-border transactions; or
- intra-group transactions.
These areas are generally considered high-risk from a tax perspective and require special attention.
🔹 Organisational or Structural Changes
Examples include:
-
- corporate reorganisations;
- demergers, mergers, or absorptions; and
- changes in ownership.
The associated tax consequences often become apparent only after the fact if no prior review has been conducted.
🔹 Before or After a Tax Audit
A tax review can:
- help a company prepare for a tax audit; or
- enable it to incorporate lessons learned from a completed audit into its operational processes.
🔹 Transition to IFRS or Group Reporting Requirements
Different accounting frameworks can also generate tax implications that should be managed consciously and appropriately.
What Benefits Does a Regular Tax Review Provide?
A well-structured tax review typically results in:
- the identification of tax risks together with practical recommendations;
- prioritised action points;
- documented tax positions;
- improved processes; and
- increased confidence for both management and the business as a whole.
A tax review is therefore not merely a compliance exercise but also an important contributor to business stability.
Regular tax reviews should not be viewed as a sign of distrust toward an accountant. Rather, they reflect a conscious and mature business approach. Forward-thinking companies do not merely react to tax issues as they arise; instead, they review their operations proactively and systematically, particularly during key business developments or periods of change.
