The audit begins before any audit — with a notice in your online tax account
Failing to comply within the time allowed is itself a ground to order a desk audit, followed by a demand to make corrections and, if your explanation falls short, a tax audit.
Common mistake: Since 1 January 2026 pre-audit analysis applies: reporting is analysed automatically by the tax authorities' information systems, without an order from the head of the authority and without the taxpayer taking part. The notice of a discrepancy lands in the online tax account, and the accountant learns about it when the response deadline is already running.
"A field audit is ten days, they won't assess anything anyway"
A ten-day audit you did not prepare for now produces a full decision on additional assessment with interest and a fine, followed by a collection order against your bank accounts.
Common mistake: The rule barring tax from being assessed on the results of a field audit was repealed by Law ZRU-758 of 11 March 2022. Companies still treat a field audit as a formality because they remember the old rule.
The ten days for objections are spent thinking it over
The company arrives at the hearing on the audit materials with no written position and no documents attached. The same dispute then costs several times more and is run from a weaker position.
Common mistake: The director signs the report assuming the signature settles nothing — and formally that is true, signing the report does not mean agreeing with it. But the objection period runs from the day the report was received, not from the day the company gets around to it.
The 50% discount on the fine is sold as a benefit
The fine really is halved if guilt is admitted and payment is made voluntarily within ten days. But admitting guilt closes off the appeal and creates a document that works against the company afterwards.
Common mistake: Accounting works out only the arithmetic of the saving and talks the director into signing. Nobody works out the other half of the equation — being held liable as a precondition for a later criminal classification.
Accounts are frozen by one person's decision
Outgoing payments stop: salaries, suppliers, loan instalments, customs clearance. The cash gap and the penalties under contracts usually exceed the tax dispute itself.
Common mistake: The grounds are mundane — reporting not filed, documents not produced. The decision is taken by the head of the tax authority, and the company hears about the freeze from its bank rather than from the inspectorate.
A month burned on a complaint that never had to be filed
While the administrative ladder runs its course, the deadline for going to court is ticking, and the higher authority upholds its subordinates' decision in the vast majority of cases.
Common mistake: Mandatory pre-trial appeal was removed from part 4 of article 231 of the Tax Code by Law ZRU-910 of 20 February 2024. A large share of advisers and websites still repeat the repealed rule.
The complaint was filed and the money was debited anyway
The inspectorate carries on with enforcement: a demand to settle the arrears, a collection order against the accounts, then enforcement against assets.
Common mistake: Filing a complaint suspends enforcement of the decision, but the law separately requires the taxpayer to notify the tax authority whose decision is being appealed, in writing, enclosing a copy of the complaint. Without that notice there is no suspension.
