Serbia enforces a comprehensive fiscalization regime under the Law on Fiscalization (Zakon o fiskalizaciji), obligating VAT-registered taxpayers to submit B2C invoice data in real-time to the Tax Administration of Serbia (Poreska Uprava Republike Srbije, PURS) for electronic certification. This applies to all consumer-facing sales, including cash, cards, and transfers, via certified fiscal devices or integrated POS/ERP systems that generate unique fiscal seals and numbers to deter evasion and support immediate audits.
As of January 2026, updates emphasize enhanced digital integration with the e-Porezi portal and stricter controls on non-compliance, aligning with Balkan digital tax initiatives while maintaining focus on B2C without broad B2B real-time mandates.

In late 2025, PURS issued updated technical guidelines on fiscalization under the Law on Fiscalization, detailing requirements for fiscal devices, e-Fiskal portal usage, XML data formats, and compliance for POS integrations. This serves as the primary official resource for businesses navigating Serbia's real-time reporting obligations.

Tired of scrolling through information about e-invoicing?
Fiscalization in Serbia is a compulsory electronic procedure where taxpayers transmit structured invoice details to PURS instantly upon issuance, receiving a unique fiscal number (broj fisikalnog racuna) and digital seal to validate transactions.
Published in 2015 and amended multiple times, the Law on Fiscalization (ZOF) mandates real-time electronic validation of B2C invoices as a key anti-evasion measure.
Key elements include:
This framework combines instant B2C reporting with flexible tools, keeping Serbia at the forefront of regional fiscal controls.
In Serbia, B2B fiscalization applies only when sales occur in retail premises, such as a company buying at a store checkout, requiring the same real-time fiscal device reporting even to legal entities or sole proprietors. Pure B2B transactions outside retail premises, like direct bulk deliveries between businesses are exempt, following standard e-invoicing rules,
B2C fiscalization is mandatory under the Zakon o fiskalizaciji (Official Gazette RS No. 153/2020) for all retail sales of goods and services to physical persons, regardless of location or payment method. The law expressly requires fiscalization of all retail transactions and advances “irrespective of the payment method,” with its definition of “payment” clearly covering cashless bank/EFT/online payments alongside cash and cards.
Our POS invoicing and fiscalization API lets you integrate fiscalization directly into your POS system, however if you are an e-commerce provider explore our e-commerce e-invoicing and fiscalization API.

Unlike B2C fiscalization, Serbia's e-invoicing mandate (under LVUP amendments) requires XML formats with signatures for B2G since 2020 and a full B2B mandate from January 1, 2023. Voluntary adoption grew beforehand, with 2026 pilots focusing on EU alignment. Full guide: E-invoicing Regulations in Serbia
Fiscalization penalties (ZOF, Serbia): Legal entities fined 200,000–2,000,000 RSD (~€1,700–€17,100) for transaction failures, unapproved devices, etc. (Arts. 15–18, ZOF). Managers: 20,000–150,000 RSD; entrepreneurs: 50,000–500,000 RSD.
