Serbia’s regulatory landscape will undergo significant changes with the implementation of new rules affecting electronic invoicing and VAT accounting, effective from April 1, 2026. These updates aim to clarify and tighten the treatment of transactions conducted in foreign currency, addressing previous ambiguities that posed compliance challenges for businesses operating in multiple currencies.
The amendments to the Rulebook on VAT and the Rulebook on Electronic Invoicing will be applicable to monthly taxpayers starting in April and to quarterly taxpayers during the April–June period. Central to these reforms is a more stringent alignment between the currency used for payment and the currency reported, particularly regarding e-invoices and VAT calculations.
Under the revised regulations, when a transaction is fully settled in foreign currency, companies are permitted to express the tax base, VAT, and individual invoice items in that same currency. However, there is a mandatory requirement that total invoice amounts—including the base, VAT, and consideration—must also be presented concurrently in Serbian dinars (RSD). This dual-reporting obligation aims to standardize practices and ensure that tax authorities can maintain consistent oversight regardless of the transaction’s currency.
In cases involving mixed payments, where transactions are partially or entirely settled in dinars, all invoice components must be reported solely in dinars. This change restricts previous flexibilities that some businesses utilized for cross-border or hybrid-currency transactions.
Amendments to the electronic invoicing system (SEF) further enhance standardization by allowing unit prices to be displayed with more than two decimal places, while all other monetary values will remain limited to two decimal places. This adjustment is intended to reinforce consistency in VAT reporting and calculation processes.
The regulatory changes are designed to improve accuracy in VAT reporting, particularly concerning cross-border and foreign exchange-linked transactions. Past discrepancies often arose due to rounding issues, exchange rate applications, and varied reporting formats.
Additionally, new guidelines clarify how specific operational scenarios should be managed. Transactions involving advance payments, internal VAT accounting, and corrections of tax records must now be processed through the electronic invoicing system to maintain traceability and uniformity.
Despite these advancements, some uncertainties remain. A notable issue pertains to invoices issued after April 1 for transactions completed before this date, as there is no clear directive on which set of rules should apply. This ambiguity creates potential compliance challenges for companies dealing with transactions spanning different reporting periods.
Practically speaking, these changes will increase the compliance burden on businesses operating with multiple currencies. Companies must ensure their invoicing systems, ERP integrations, and accounting practices align with the new dual-currency reporting requirements—especially those in sectors like trade, energy, and services that are heavily exposed to foreign currency flows.
The reforms also enhance legal certainty by providing clearer guidelines on currency presentation, VAT calculation, and invoice structure. This clarity reduces the likelihood of disputes with tax authorities and minimizes the risk of incorrect VAT deductions—an area that has previously led to financial penalties for companies.
Overall, these regulatory updates reflect Serbia’s movement towards a more standardized VAT reporting framework aligned with EU practices. The emphasis on precise compliance over flexibility indicates a shift toward a more predictable environment for cross-currency transactions.
