Picture this. It’s a regular Tuesday morning at your Belgrade office. You’re halfway through your coffee when an email arrives — your company has been selected for a tax inspection by the Serbian Tax Administration. Or perhaps your statutory auditors have confirmed their engagement for the upcoming financial year and need your documentation within three weeks.
What happens next? If your stomach just dropped, you’re not alone. For many companies operating in Serbia — especially foreign-owned ones still finding their footing in the local regulatory landscape — an audit triggers a frantic scramble. Someone starts digging through folders. Someone else is calling the bookkeeper asking about missing invoices from seven months ago. The finance director back at HQ is asking questions no one can confidently answer.
It doesn’t have to be this way. And frankly, it shouldn’t be.
The companies that sail through audits and inspections aren’t doing anything extraordinary. They’re simply keeping their books properly throughout the year — not just when someone’s about to look at them. That’s what proactive accounting means, and in Serbia’s regulatory environment, it’s one of the smartest investments you can make.

Let’s get the basics straight. Under Serbian law, statutory audits are mandatory for all medium-sized and large entities, as well as for certain smaller companies that exceed specific revenue thresholds. Financial institutions, public companies under the Capital Markets Law, and companies preparing consolidated financial statements are also required to undergo audit.
But here’s the point many business owners miss: even if your company isn’t required to have a statutory audit, you’re not off the hook. The Serbian Tax Administration has broad enforcement powers and can conduct comprehensive tax audits at any time. They can review your books, impose fines, and issue enforceable tax assessments. In serious cases, tax violations can escalate from administrative penalties to criminal prosecution under Article 229 of the Criminal Code.
So whether you’re dealing with a planned statutory audit or an unannounced tax inspection, the question is the same — are your books ready to be examined right now?
When an auditor or tax inspector sits down with your records, they’re not trying to catch you being creative. They’re checking whether your company follows the rules consistently and transparently. Here are the key areas they focus on.
Properly maintained books. Serbian law requires that accounting records are kept in the Serbian language and denominated in Serbian Dinars (RSD). Your books must follow the applicable financial reporting framework — full IFRS for large entities, IFRS for SMEs for small and medium-sized companies, or the National Rulebook for micro entities. This isn’t optional, and getting it wrong creates problems that cascade through every other part of the audit.
The Internal Accounting Rulebook. Under Article 7 of the Law on Accounting, every legal entity in Serbia must maintain an Internal Accounting Rulebook (Pravilnik o računovodstvu). This document defines your accounting policies, describes your internal controls, and establishes the procedures your company follows. Auditors will ask for it. If it’s outdated, incomplete, or — worse — nonexistent, that’s an immediate red flag.
Timely filings. Annual financial statements must be submitted to the Business Registers Agency (APR) by specific deadlines. Financial statements for public disclosure are due by March 31 of the current year for the previous year, while the full submission deadline falls on June 30. Companies with consolidated statements have until July 31. Missing these deadlines isn’t a minor administrative oversight — it’s an economic offense that carries real penalties.
E-invoicing compliance. Since Serbia mandated electronic invoicing for all B2B and B2G transactions through the SEF platform (Sistem Elektronskih Faktura), compliance is no longer optional. Every invoice must be issued, validated, and archived through the system. Inspectors can easily cross-reference your reported figures against what’s in the SEF. Discrepancies will raise questions.
Proper documentation. This is where many companies struggle, especially with intercompany transactions. Every cost you want to deduct must be backed by a reliable accounting document showing the basis, type, and content of the transaction. An invoice alone is often not enough — you may need contracts, delivery confirmations, proof of services rendered, or acceptance protocols. Undocumented costs can be reclassified as non-deductible, which directly increases your tax liability.
Transfer pricing documentation. If your Serbian entity transacts with related parties — a parent company abroad, a sister subsidiary, an affiliated entity — those transactions fall under transfer pricing scrutiny. Documentation must demonstrate arm’s length pricing using accepted methodologies aligned with OECD guidelines. The Serbian Tax Administration actively reviews transfer pricing during audits, so this is not an area where you can afford to be vague.
Let’s talk numbers. Serbian law prescribes fines ranging from RSD 100,000 to RSD 3,000,000 for legal entities that commit economic offenses related to accounting and financial reporting. And the liability doesn’t stop at the company level — the CEO or responsible person can face personal fines as well.
For e-invoicing violations specifically, penalties for companies range from RSD 50,000 to RSD 2,000,000, with separate fines for company directors.
But the financial penalties are only part of the picture. Consider what else goes wrong when your books aren’t audit-ready:
Here’s where we get practical. “Proactive accounting” isn’t a buzzword — it’s a set of habits and systems that keep your Serbian entity compliant and audit-ready every day of the year, not just in the weeks before someone comes to check.
Real-time bookkeeping, not quarter-end batch processing. If your bookkeeper is processing three months of invoices in a single weekend, you don’t have a bookkeeping system — you have a backlog. Transactions should be recorded as they happen. This keeps your ledger current, makes monthly reporting meaningful, and eliminates the chaotic catch-up sessions that breed errors. If you’re still running things this way, it might be time to rethink your bookkeeping approach.
Monthly reconciliations. Bank accounts, receivables, payables, intercompany balances — these should be reconciled every month, not once a year when the auditor asks. Monthly reconciliation catches discrepancies early, when they’re easy to fix. By year-end, they’ve become archaeological projects.
A living Internal Accounting Rulebook. Your Pravilnik shouldn’t be a document you wrote once during company formation and never touched again. It should reflect how your company actually operates today — your current chart of accounts, your actual approval workflows, your real internal controls. Update it whenever your processes change.
Organized documentation from day one. For every significant transaction, ask yourself: if an auditor looked at this in eighteen months, would they understand what happened and why? Keep contracts, delivery notes, board decisions, approval chains, and supporting calculations organized and accessible. Digital archiving helps enormously here.
Regular compliance health checks. Don’t wait for an external audit to discover problems. Conduct internal reviews — quarterly at minimum — to check that filings are on time, that the SEF is up to date, that employee records are in order, and that nothing has fallen through the cracks. Think of it as preventive maintenance for your financial operations.
Stay current on regulatory changes. Serbian accounting and tax regulations evolve. New rules around e-invoicing, changes to reporting requirements, updated guidance on deductibility — these things affect how you book transactions and prepare statements. Ignorance of a new requirement is never accepted as an excuse by inspectors.
If you’re a foreign company operating in Serbia, you’re navigating a system that has its own standards, its own language requirements, its own filing rhythms, and its own enforcement culture. Your headquarters finance team — no matter how skilled — is unlikely to be fluent in Serbian IFRS implementation, APR filing procedures, or the practical realities of a Serbian tax inspection.
This is where having a local accounting partner pays for itself. A good local firm doesn’t just process your transactions and file your returns. They act as your early warning system — catching compliance gaps before they become audit findings, keeping your Internal Accounting Rulebook current, and making sure you’re never surprised by a deadline or a regulatory change.
For companies still in the process of setting up in Serbia, getting this right from the start is even more important. The habits you establish during company formation — how you structure your chart of accounts, which systems you use, how documentation flows — will determine whether your first audit is a formality or a headache.
How do I know if my Serbian company needs a statutory audit? Statutory audits are mandatory for medium-sized and large entities in Serbia, as well as for financial institutions and public companies. Certain smaller companies that exceed specific revenue thresholds are also required to have one. Your classification depends on your average number of employees, annual income, and total asset value. A qualified accountant can assess your classification and let you know.
What happens if we miss the deadline for filing financial statements? Late filing of financial statements is classified as an economic offense under the Law on Accounting. The company can be fined between RSD 100,000 and RSD 3,000,000, and the responsible person (typically the CEO) can face a separate personal fine. The deadlines are firm — March 31 for public disclosure, June 30 for full submission to the APR.
Can our headquarters accounting team handle Serbian compliance remotely? In theory, partially. In practice, it’s very difficult. Serbian books must be kept in Serbian and in RSD. Financial statements must follow local IFRS implementation. E-invoicing must go through the SEF platform. Filing with the APR has specific format and timing requirements. Most foreign HQ teams find they need a local bookkeeping partner to handle the day-to-day compliance properly.
What is the Internal Accounting Rulebook, and why does it matter? The Internal Accounting Rulebook (Pravilnik o računovodstvu) is a mandatory internal document required under Article 7 of the Law on Accounting. It outlines your accounting policies, your chart of accounts, your internal controls, and your procedures for financial reporting. Auditors and inspectors routinely ask for it, and an outdated or missing rulebook is a common — and avoidable — audit finding.
How often should we expect tax inspections? There’s no fixed schedule. The Serbian Tax Administration can initiate an inspection at any time based on risk assessment, random selection, or specific triggers like unusual reporting patterns. The best approach is to assume that an inspection could happen at any point and maintain your records accordingly.
