Serbia’s National Assembly approved a broad package of tax and business-regulation measures on Aug. 31, setting the framework for significant changes to corporate compliance from 2027.
- Digital transaction data becomes central to tax compliance
- SEF rules extend to customs and agricultural transactions
- Corporate tax measures follow a phased timetable
- Carbon taxation adds reporting obligations
- Carbon data gains importance for industrial exporters
- State-controlled companies face wider governance rules
- Trade-practice rules enter full implementation
- Businesses move from legislative monitoring to implementation
The legislation covers electronic invoicing, electronic dispatch notes, fiscalisation, tax procedures, VAT, corporate income tax, excise duties, social-security contributions, free zones and carbon taxation, alongside new governance requirements for parts of the state-controlled corporate sector.
Most of the provisions are scheduled to take effect on Jan. 1, 2027, leaving businesses roughly four months to adjust accounting systems, enterprise resource planning platforms and internal tax controls before implementation. The measures move the Serbian tax system further toward linking corporate reporting with digital transaction data, particularly through the SEF electronic invoicing platform and the emerging SiTAX environment.
Digital transaction data becomes central to tax compliance
The new framework is expected to affect virtually all companies registered for VAT, with the largest implementation requirements likely to fall on businesses handling high transaction volumes, complex supply chains or multiple accounting and logistics systems.
Manufacturers, wholesalers, retailers and large corporate groups will need to ensure that information stored in commercial systems corresponds with data transmitted through electronic invoicing and tax-reporting platforms. As these systems become more interconnected, discrepancies between ERP records, SEF invoices and VAT reporting will become easier to identify. This increases the importance of master-data management, transaction coding and automated reconciliation within corporate tax controls. The changes also require closer coordination between finance functions and IT, procurement, sales and logistics departments, as tax compliance becomes increasingly linked to operational transaction data.
SEF rules extend to customs and agricultural transactions
Amendments to Serbia’s Law on Electronic Invoicing are scheduled to apply largely from Jan. 1, 2027, with additional functions due to begin on July 1, 2027. The later provisions include electronic recording of certain purchases from agricultural producers and access through SEF to information from export customs declarations.
The changes will further connect invoicing with customs, procurement and VAT data, particularly affecting exporters, distributors and companies operating extensive procurement networks.
Businesses will need to review the consistency of customer, supplier, tax-status and transaction information across their systems, rather than focusing solely on the technical ability to issue invoices through SEF.
Corporate tax measures follow a phased timetable
Changes to corporate income tax will be introduced in stages. Some provisions are set for Jan. 1, 2027, while others will take effect from Jan. 1, 2028. A further group of rules connected with European Union alignment would apply only after Serbia joins the bloc.
The legislation retains transitional treatment for certain companies that already qualify for investment incentives, making implementation timing relevant for businesses preparing significant capital expenditure. Companies intending to use existing investment reliefs will need to establish whether they satisfy the applicable eligibility requirements before the relevant deadlines, particularly where manufacturing, technology or infrastructure projects incorporate tax incentives into their financial models.
The amendments also strengthen the anti-abuse framework in line with Serbia’s longer-term EU tax alignment. Documentation of the commercial rationale for complex corporate structures, intra-group financing arrangements and transactions generating substantial tax benefits therefore becomes more significant. For multinational companies, the framework places greater emphasis on economic substance and supporting documentation alongside formal legal structures.
Carbon taxation adds reporting obligations
The parliamentary package also includes amendments concerning Serbia’s greenhouse-gas emissions tax and taxation of imports of carbon-intensive products.
The measures are particularly relevant to electricity producers and carbon-intensive industries including cement, steel, aluminium and fertiliser production. For qualifying investments in the electricity sector, the revised system provides a tax credit equal to 20% of eligible decarbonisation investment costs, subject to a ceiling of 80% of the applicable greenhouse-gas tax liability. The measure falls under Serbia’s state-aid framework.
Companies investing in renewable generation, energy efficiency, storage and other emissions-reduction projects will need to establish whether their planned expenditure satisfies the eligibility conditions. Special reporting provisions also cover carbon-tax periods ending by Dec. 31, 2026, with filings due between April 1 and May 31, 2027.
Carbon data gains importance for industrial exporters
The reporting timetable coincides with preparations by exporters for the European Union’s Carbon Border Adjustment Mechanism, although Serbia’s domestic carbon taxes and the EU CBAM system remain separate regulatory frameworks. Both systems increase the need for auditable information covering emissions, energy consumption, production and imported materials.
For industrial companies trading with the EU, carbon-related information is consequently becoming increasingly integrated into broader financial and corporate compliance processes rather than being handled solely as an environmental reporting matter.
State-controlled companies face wider governance rules
The Assembly also approved amendments to the Law on Prevention of Corruption, expanding compliance requirements within parts of Serbia’s state-controlled corporate sector. The revised framework broadens the group of officials potentially covered by conflict-of-interest, reporting and integrity requirements at public enterprises and companies controlled by the state, autonomous provinces or municipalities.
The provisions are particularly relevant to directors, supervisory board members, executive board members and public-sector shareholder representatives. State-controlled companies will need to determine which members of their executive and supervisory structures fall within the expanded regulatory scope once the legislation enters into force. The measures affect governance arrangements across public utilities, infrastructure companies and other enterprises combining corporate and public-sector ownership structures.
Trade-practice rules enter full implementation
The tax package arrives as companies face another regulatory deadline beginning Sept. 1 under the Law on Trade Practices for Certain Types of Products. The legislation governs commercial relationships between buyers and suppliers in agricultural and food supply chains and also covers several other product categories.
Retailers, food manufacturers, distributors and agricultural suppliers are among the businesses most directly affected. Companies have had four months to bring commercial agreements, general terms and internal practices into line with the new requirements. Large retail chains also face enhanced digital price-transparency obligations, including the publication and regular updating of price lists.
Businesses move from legislative monitoring to implementation
The Aug. 31 parliamentary approval moves Serbia’s 2027 regulatory programme from the legislative stage into implementation. Finance departments must now map the VAT and tax changes, while IT teams prepare ERP and SEF interfaces. Legal departments will need to assess investment incentives and corporate structures, and industrial companies subject to carbon taxation will have to strengthen emissions data and supporting documentation. The immediate remaining legal step is publication of the adopted legislation in the Official Gazette, which will establish the formal entry-into-force dates.
For businesses working toward the Jan. 1, 2027 deadlines, however, implementation preparations are already required. Serbia’s corporate compliance framework is moving toward a model in which invoices, tax records, customs information, payments and commercial transactions can be compared across government digital systems, increasing the importance of data accuracy and internal controls alongside the substantive interpretation of tax rules.
