Serbia Amends E-Invoicing Rules for 2025: Key SEF & VAT Updates

B2B e-invoicing became mandatory in 2023 when the Serbian government introduced Sistem E-Faktura (SEF) for transactions between public and private sector entities, that is, for B2G and B2B transactions. All VAT-registered businesses are obliged to exchange e-invoices. Additionally, companies not registered for VAT but need to issue any request for payment to public entities must also register for SEF and transmit data in XML format.

On December 30, 2025, the Serbian Ministry of Finance released the Regulation on Amendments to the Regulation on Electronic Invoicing (Regulation), effective January 1, 2025.

Key Amendments to the Regulation

One of the amendments adopted extends the deadline for electronic tax recording and VAT calculation from ten to 12 days after the tax period. Furthermore, corrections to electronic tax recordings are now allowed for incorrect and incomplete data. In contrast, the obligation to correct electronic tax recordings for invoices received late or other changes is removed. Additionally, VAT Summary Records must now include turnover of travel agencies, second-hand goods, works of art, collectors' items, antiques, and retail turnover.

Regarding customs declaration, new rules specify that the list of customs declarations is automatically created in SEF based on declarations and other documents relevant to customs clearance of imported or delivered goods released for free circulation.

Furthermore, following the amendments, when issuing e-invoices with the relevant tax category, any amount not subject to charges is recorded under tax category ”N”, along with the corresponding application code. Additionally, e-invoices issued as documents for reductions or increases must now include the date of adjustments.

The Ministry of Finance also extended the verification of electronic VAT records to June 30, 2025, allowing businesses time to adapt to the new rules.

Conclusion

The latest amendments to the Serbian e-invoicing system, such as extending deadlines, simplifying correction procedures, and enhancing the automation of customs declarations, aim to improve businesses' efficiency and compliance. 

Furthermore, temporarily postponing VAT record verification until mid-2025 gives businesses enough time to align with the new requirements.
