Serbia’s e-Invoicing Rulebook Goes Beyond Invoicing: Toward Integrated VAT-Data Orchestration and Preliminary Returns

 

• The latest amendment turns SEF into a VAT-data engine, not just an invoice channel. The newest amendment to the Rulebook on Electronic Invoicing appeared on Serbia’s official legal-information portal on 5 August 2026, after formal publication in Official Gazette No. 71/2026 on 31 July 2026. It refines input-VAT cut-offs, corrections and updates, and introduces preliminary VAT-return preparation — with SEF able to populate three prescribed forms (PPP PDV, Annex 1 and Annex 2) through automatic and manual input.
• The same transactional data is now reused across invoicing, VAT records and the future preliminary return. Data flows automatically from electronic invoices, the Summary and Individual VAT Records and the Input VAT Record into the preliminary return, on prescribed cut-off snapshots tied to the 10th/12th-day deadlines. This makes tax determination, ERP data quality, invoice content and process design decisive: an error created at source flows directly into the wider VAT compliance chain rather than staying in a single document.
• Timing is staggered, so the window to prepare is closing. Most No. 30/2026 rules apply to tax periods beginning after 31 March 2026, while the preliminary-return provisions apply to tax periods beginning after 31 December 2026. Practically, organisations should map every invoice and non-invoice flow to the correct SEF document or VAT record, establish a controlled reconciliation and sign-off before the cut-offs, and define ownership for intermediary management, exceptions, evidence and outage procedures. This is an unofficial English translation prepared by Revo — the original Serbian text prevails.

Serbia has published an amended Rulebook on E-Invoicing

• Serbia’s Ministry of Finance updated its Rulebook on Electronic Invoicing on August 5, 2026, primarily enhancing the SEF platform’s VAT reporting capabilities rather than expanding mandatory e-invoicing.
• Key changes, effective for VAT periods starting after December 31, 2026, include the SEF generating a preliminary VAT return, new data fields for enhanced VAT reporting, and new rules for input VAT record submission and correction.
• The updated Rulebook also details mechanisms for correcting and updating input VAT records, clarifies procedures for SEF outages, and requires taxpayers to assess the impact on their VAT reporting and compliance processes.
