Serbia’s Draft VAT Reform Links Quarterly Reporting to Liquidity Management for SMEs

Serbia’s proposed new Value Added Tax Law outlines a shift toward more digital tax administration, tighter transaction reporting and a clearer split between monthly and quarterly VAT taxpayers, with rules designed to take effect upon the country’s accession to the European Union.

The draft preserves the monthly VAT period as the default structure, while introducing quarterly reporting eligibility for smaller businesses, alongside stricter conditions for cross-border transactions and foreign entities operating in Serbia.

Quarterly VAT Threshold Introduced for Smaller Taxpayers

Under the proposal, taxpayers with annual turnover of goods and services below RSD 50mn, including VAT, in the previous calendar year would be allowed to file VAT returns quarterly.

Eligible businesses would still retain the option to continue monthly filing voluntarily, depending on accounting structure, cash-flow needs or refund positions. The framework establishes monthly reporting as the standard system, with quarterly filing positioned as a conditional administrative alternative for smaller entities.

Cash-Flow Timing Emerges as Key Economic Effect

While quarterly VAT reporting is framed as an administrative simplification, its primary financial impact lies in liquidity management. Businesses filing quarterly retain VAT collected from customers for longer periods before remitting it to the tax authority, effectively creating a temporary working-capital buffer.

This structure allows firms to deploy collected VAT during the quarter for operating costs such as wages, rent, energy, inventory and logistics before settling tax obligations at the end of the reporting period.The system does not reduce tax liability, but alters the timing of payment flows.

EU-Linked Transactions Remain Under Monthly Control

The draft law excludes certain categories from quarterly eligibility. Companies involved in transactions within the European Union would remain subject to monthly VAT reporting regardless of turnover levels.

The same rule applies to foreign entities without a registered seat, residence or permanent establishment in Serbia that are VAT-registered in the country. This approach reflects requirements for higher-frequency reporting and enhanced monitoring of cross-border VAT mechanisms, including reverse-charge and intra-community transaction structures.

Electronic Reporting and Pre-Filled VAT Returns Introduced

The proposed system strengthens Serbia’s shift toward digital tax administration, requiring all VAT returns to be submitted electronically within 15 days after the end of the tax period. Filing obligations would apply even when no VAT is due. Returns must include detailed data on taxable supplies, calculated VAT, input VAT, exempt transactions and non-taxable operations, with additional reporting required for EU-related trade flows.

A key innovation is the introduction of a preliminary VAT return generated through the electronic invoicing system, which automatically compiles available transaction data. Taxpayers would be required to reconcile, confirm or correct this pre-filled return, marking a move toward a more automated VAT control model.

Increased Data Integration Between Taxpayers and Authorities

The system embeds VAT reporting into Serbia’s electronic invoicing infrastructure, linking invoice issuance, tax calculation and reporting into a unified data flow. Errors in invoicing, timing mismatches or incomplete documentation are expected to directly affect VAT return accuracy.

The draft law also requires a final VAT return submission when taxpayers exit the VAT system, covering the period from the start of the tax cycle to the deregistration date.

Expanded Scope of VAT Filing Obligations

The obligation to file VAT returns extends beyond standard registered taxpayers. Additional categories include persons paying VAT on behalf of foreign taxpayers without a Serbian establishment, non-VAT-registered legal entities acquiring goods from EU member states, buyers of new means of transport from the EU, and businesses supplying certain services to foreign taxpayers or third-country entities.

The structure reflects a transaction-based VAT system in which liability follows economic activity rather than taxpayer status alone.

Market Structure Shows Dominance of Monthly Filers

Market data from CompanyWall indicate that 5,312 businesses were active monthly VAT filers in 2026, compared with 2,602 quarterly filers.

Historical data show limited movement between reporting regimes, with only 278 monthly-to-quarterly changes and six quarterly-to-monthly changes in 2023, followed by 167 monthly and four quarterly changes in 2024, and 79 monthly changes in 2025. The figures suggest that many eligible firms remain in monthly reporting by default.

Structural Factors Behind Filing Preferences

Businesses often retain monthly filing due to tighter documentation control, earlier identification of accounting errors and faster access to VAT refunds. Companies with frequent input VAT claims, import-heavy operations or capital investment cycles also tend to prefer monthly reporting.

By contrast, firms with stable domestic revenue streams and positive VAT positions are more likely to benefit from quarterly reporting’s liquidity effect. Administrative inertia also contributes to low switching rates between reporting periods.

Electronic VAT System Becomes Central Compliance Tool

The draft law reinforces the role of Serbia’s electronic invoicing system as the core mechanism for VAT calculation and verification. The system is expected to enable tax authorities to cross-check transactions in real time, improving detection of inconsistencies in input VAT claims, undeclared supplies and transaction chains. Tax compliance is increasingly defined as data accuracy and system reconciliation rather than periodic manual reporting.

Policy Direction Linked to EU Accession Framework

The reform is structured as part of Serbia’s alignment with European Union VAT standards, including requirements for transaction reporting, intra-community trade rules, exemptions and administrative cooperation.

The proposed law would apply from the date of EU accession, positioning it as a preparatory framework for integration into the EU fiscal system.

The structure signals a broader transition toward EU-compatible tax infrastructure, with increasing emphasis on electronic reporting, pre-filled returns and harmonised VAT procedures across borders.
