Regulatory updates - Serbia

The amendments to the Rulebook published in the Official Gazette No. 71/2026 focus primarily on VAT record-keeping, preliminary VAT return generation, input VAT reporting, and related SEF functionality enhancements, rather than expanding the scope of mandatory e-invoicing. 

Key updates include, among others: 

• Preliminary VAT Return: SEF will generate a preliminary VAT return based on e-invoices, VAT records, and input VAT records maintained in the system. The new framework applies to VAT periods beginning after December 31, 2026.  

• Enhanced VAT reporting: New data fields and reporting rules have been introduced for taxable amount and VAT increases/decreases, advance payment reductions, cancellations (storno), and corrections.  

• Input VAT records: Input VAT reporting must be submitted by the 12th day of the month following the VAT period. The Rulebook also introduces new rules for automatic population, corrections, updates, and interaction with the preliminary VAT return process.   

• Correction and update mechanisms: Detailed procedures clarify how input VAT records may be corrected or updated, including restrictions once the preliminary VAT return or VAT return has been submitted.  

• SEF outages: New procedures clarify how temporary SEF interruptions are handled, including user notifications and deadline change where outages prevent timely VAT reporting. 

Taxpayers should evaluate the impact on their VAT reporting, correction procedures, and SEF-related compliance processes ahead of the new preliminary VAT return functionality becoming effective in 2027.
