How to Issue a Tax-Compliant Invoice in Serbia: SEF Requirements

Issuing a tax-compliant invoice in Serbia isn't just good practice — it's a legal requirement. The Sistem Elektronskih Faktura (SEF) sets strict rules about what every invoice must contain, how VAT (PDV) should be calculated, and how long records must be retained.

Whether you're a freelancer, small business owner, or running a growing company, this guide covers everything you need to create invoices that satisfy SEF requirements and keep your business audit-ready.

Why Invoice Compliance Matters in Serbia

A compliant invoice does more than request payment — it creates a legal record that protects both you and your client. SEF uses invoices to verify tax declarations, track VAT (PDV) collections, and identify non-compliant businesses.

Non-compliant invoices can lead to:

• Rejected tax deductions for your clients (they can't claim input VAT (PDV))
• Penalties and interest from SEF
• Failed audits and additional scrutiny
• Damaged business reputation and client trust
