Tax Mistakes Freelancers Make in Serbia (and How to Avoid Them)

Freelancing in Serbia gives you freedom, but it also gives you full responsibility for your taxes. The Sistem Elektronskih Faktura (SEF) expects freelancers to manage their own VAT (PDV) and income tax — and mistakes can be costly.

Here are the most common tax errors Serbian freelancers make and how to avoid them.

1. Not Registering for VAT (PDV) on Time

Once your taxable turnover exceeds RSD 8 million annual turnover, you must register for VAT (PDV). Delaying registration means you owe VAT (PDV) from the date you should have registered, plus penalties.

2. Not Setting Money Aside for Tax

Unlike employees, freelancers don't have tax deducted at source. Many Serbian freelancers spend their gross income and face a painful bill at tax time.

3. Missing Legitimate Deductions

Many freelancers in Serbia leave money on the table by not claiming all allowable deductions. Common missed deductions include:

• Home office costs (proportional rent, utilities, internet)
• Professional development and training
• Software subscriptions and tools
• Travel for business purposes
• Professional insurance
• Accounting and legal fees

Fix: Use expense tracking software to capture every business expense as it happens.

4. Mixing Personal and Business Finances

Using one bank account for everything makes it nearly impossible to accurately calculate business income and expenses. SEF may question deductions you can't clearly separate from personal spending.

Fix: Open a dedicated business account and route all business income and expenses through it.

5. Poor Record Keeping

SEF requires records to be kept for 10 years. Lost receipts and incomplete records lead to disallowed deductions during audits.

Fix: Go digital. Scan receipts immediately and use invoicing software that stores everything securely.

Fix: Set calendar reminders or use software that alerts you before deadlines.

7. Not Issuing Compliant Invoices

Invoices missing required elements (like your PIB) can be rejected by SEF during audits, and your clients lose the ability to claim input VAT (PDV).
