Serbia has adopted a wide-ranging package of tax and business regulation changes that will reshape corporate compliance from 2027, expanding digital reporting, changing VAT and corporate tax rules and introducing new obligations for companies exposed to carbon taxation and state-controlled governance requirements.
The National Assembly approved the measures on Aug. 31 after several days of committee and plenary debate, moving the package from draft legislation into the implementation phase ahead of publication in the Official Gazette.
The legislation covers electronic invoicing, electronic dispatch notes, fiscalisation, tax procedure, VAT, corporate income tax, excise duties, social-security contributions, free zones and Serbia’s emerging carbon taxation framework.
For companies, the most important shift is the increasing integration of tax reporting with digital transaction data.
Many of the core provisions are due to apply from Jan. 1, 2027, giving businesses roughly four months to adapt accounting systems, enterprise resource planning software and internal tax controls.
Serbia has steadily expanded electronic tax administration in recent years, particularly through its SEF electronic invoicing platform. The latest package moves that process further by connecting invoicing, VAT reporting and tax administration more closely with the new SiTAX environment.
The changes are expected to affect virtually all companies registered for VAT, but the largest implementation burden is likely to fall on businesses with high transaction volumes, complex supply chains or multiple accounting and logistics systems.
Manufacturers, wholesalers, retailers and large corporate groups will need to ensure that data recorded in commercial systems matches information transmitted through electronic invoicing and tax reporting platforms.
The risk for companies is increasingly shifting away from traditional errors in annual tax filings towards inconsistencies in transaction-level data.
An invoice classified one way in an ERP system and differently in SEF or a VAT return could become easier for tax authorities to identify as digital systems become more interconnected.
That is likely to make master-data management, transaction coding and automated reconciliation more important parts of corporate tax governance.
Electronic invoicing expands further
Amendments to Serbia’s Electronic Invoicing Law will apply largely from Jan. 1, 2027, while additional functions are scheduled from July 1, 2027.
Those later changes include electronic recording of certain purchases from agricultural producers and access to export customs declaration information through SEF.
For exporters, distributors and companies operating large procurement networks, the changes will further integrate invoicing with customs, procurement and VAT information.
Businesses will need to review whether customer, supplier, tax-status and transaction data are consistent across different systems rather than focusing only on whether invoices can technically be issued through SEF.
The transition is likely to require closer cooperation between finance departments and IT, procurement, sales and logistics teams.
Corporate tax changes phase in
The corporate income tax amendments use a staggered timetable.
Some provisions will take effect from Jan. 1, 2027, while others are scheduled for Jan. 1, 2028. A broader layer of rules linked to European Union alignment would apply only after Serbia joins the bloc.
The legislation also preserves transitional treatment for certain companies already qualifying for investment incentives.
That makes timing important for businesses planning major capital expenditure.
Companies seeking to rely on existing investment reliefs will need to confirm whether they meet qualifying conditions before the relevant cut-off dates, particularly where large manufacturing, technology or infrastructure projects depend on tax incentives in their financial models.
The changes also introduce a stronger anti-abuse framework linked to Serbia’s longer-term EU tax alignment.
That will increase the importance of documenting the commercial rationale behind complex corporate structures, intra-group financing and other arrangements producing significant tax benefits.
For multinational groups, the direction of travel is towards a system in which economic substance and documentation will carry greater weight alongside formal legal structure.
Carbon rules bring new reporting burden
Parliament also approved amendments to Serbia’s greenhouse-gas emissions tax and the tax on imports of carbon-intensive products.
The measures are particularly important for electricity producers and companies operating in carbon-intensive sectors such as cement, steel, aluminium and fertilisers.
For qualifying electricity-sector investments, the revised framework provides a tax credit equal to 20% of eligible decarbonisation investment costs, capped at 80% of the relevant greenhouse-gas tax liability.
The measure is treated within Serbia’s state-aid framework.
Companies investing in renewable generation, energy efficiency, storage or other emissions-reduction projects will need to determine whether proposed spending meets the eligibility criteria.
Special reporting arrangements also apply to carbon-tax periods ending by Dec. 31, 2026, with filings due between April 1 and May 31, 2027.
The timetable means affected companies will have to prepare emissions and import data during the same period in which many exporters are also adapting to the European Union’s Carbon Border Adjustment Mechanism.
Although Serbia’s domestic carbon taxes and the EU CBAM regime are separate systems, both increase pressure on companies to produce auditable data on emissions, energy use, production and imported materials.
For industrial groups trading with the EU, carbon data is increasingly becoming part of mainstream financial and compliance reporting rather than a standalone environmental issue.
State-owned companies face governance changes
Parliament also adopted amendments to the Law on Prevention of Corruption that expand compliance obligations across parts of Serbia’s state-controlled corporate sector.
The changes widen the category of officials potentially subject to conflict-of-interest, reporting and integrity requirements within public enterprises and companies controlled by the state, autonomous provinces or municipalities.
Directors, supervisory board members, executive board members and public-sector shareholder representatives are among those most likely to be affected.
State-controlled companies will need to map which executives and board members fall within the expanded regulatory perimeter once the legislation enters into force.
The measures are particularly relevant to public utilities, infrastructure companies and other enterprises with mixed corporate and public-sector governance structures.
Retail regulation already takes effect
The broader tax package comes as Serbian companies face another regulatory deadline from Sept. 1.
Full implementation begins for the Law on Trade Practices for Certain Types of Products, which regulates commercial relationships between buyers and suppliers in agricultural and food supply chains and extends to several other product categories.
Retailers, food producers, distributors and agricultural suppliers are among the most exposed companies.
Affected businesses have had four months to align commercial agreements, general terms and internal practices with the new rules.
Large retail chains also face tighter digital price transparency requirements, including the publication and regular updating of price lists.
The measures increase the compliance burden in Serbia’s retail sector at a time when retailers are already adjusting to higher labour costs and tighter competition oversight.
Companies shift from legal monitoring to implementation
For Serbian businesses, the Aug. 31 parliamentary vote changes the nature of the 2027 regulatory programme.
Until now, many companies could treat the measures as proposals and prepare alternative implementation scenarios.
The focus now moves towards execution.
Finance departments will need to map VAT and tax changes, IT teams will have to test ERP and SEF interfaces, legal teams will need to review investment incentives and corporate structures, while industrial companies exposed to carbon taxation will have to strengthen emissions data and documentation.
The remaining immediate legal step is publication in the Official Gazette, which will determine the exact formal entry-into-force dates of the newly adopted laws.
But for businesses facing Jan. 1 implementation deadlines, the practical transition has already begun.
Serbia’s corporate regulatory model is increasingly moving towards continuous digital supervision in which invoices, tax records, customs data, payments and commercial transactions can be compared across government systems.
That is likely to make data quality and internal controls as important to corporate compliance as the interpretation of the tax rules themselves.
