Serbia is preparing a broad overhaul of its corporate tax and compliance framework, with Parliament set to consider proposed changes covering VAT, corporate income tax, electronic invoicing, electronic dispatch notes, fiscalisation, tax procedure, excises, carbon taxation and investment-related regimes. The National Assembly has scheduled an extraordinary session for 24 August 2026, putting the package on the legislative agenda ahead of a proposed implementation cycle that would begin largely on 1 January 2027.
- Parliament to consider broad tax and compliance changes
- VAT reform increases the importance of transaction data
- Electronic invoicing moves beyond invoice transmission
- Corporate tax proposals strengthen anti-abuse rules
- Investment incentives face transitional considerations
- Carbon taxation adds new requirements for energy-intensive sectors
- ERP systems become central to tax controls
- Higher minimum wages add to 2027 cost planning
- Outsourcing does not remove responsibility for data quality
- Companies face a 2026 preparation window
The proposed measures would extend the digitalisation of Serbia’s tax administration through transaction-level reporting, interconnected government databases and stronger anti-abuse provisions. The framework would increasingly allow invoices, VAT, payments, dispatch information and corporate tax data to be reconciled across systems. For companies, this makes 2027 a systems and data-management exercise as well as a tax-planning issue.
Parliament to consider broad tax and compliance changes
The extraordinary-session agenda contains dozens of legislative items. Business-relevant proposals cover electronic invoicing, electronic dispatch notes, fiscalisation, tax procedure, VAT, corporate income tax, personal income tax, compulsory social-security contributions, excises, free zones, greenhouse-gas emissions taxation and carbon-related imports. The package also includes measures affecting planning and construction, state aid and public-debt-related rules, extending its implications into investment, development and infrastructure planning.
The parliamentary stage remains significant because the measures are still proposals rather than enacted legislation. Final wording, amendments and transitional arrangements may therefore change. Businesses face two parallel requirements: monitoring the legislative process while preparing their systems for the proposed rules. Waiting for final adoption before beginning internal systems analysis could leave companies with a compressed implementation period.
VAT reform increases the importance of transaction data
The proposed VAT amendments are among the measures with the broadest operational implications. Many provisions are scheduled for implementation from 1 January 2027, with implementing regulations expected before the end of 2026. The changes are being developed alongside the Tax Administration’s new SiTAX environment, which is expected to increase the use of structured digital information in tax reporting.
As tax administration becomes more digital, companies will increasingly need consistency between their accounting systems, invoices, fiscalisation records, VAT classifications and tax returns. A transaction may therefore have to maintain the same underlying information from the commercial contract and purchase order through invoice issuance, accounting treatment, VAT classification and tax reporting.
The principal compliance challenge is not necessarily the headline VAT rate but consistency of corporate data. Differences between ERP records, the Electronic Invoice System, fiscalisation information and tax returns can generate discrepancies even where the underlying transaction is legitimate. For larger companies, implementation is consequently likely to involve tax, finance, accounting, procurement, sales, logistics and IT departments. Smaller businesses may face additional pressure where they rely heavily on external accountants and basic software systems that require upgrading.
Electronic invoicing moves beyond invoice transmission
Serbia’s Electronic Invoice System (SEF) is also expected to receive additional functionality. Under the proposed framework, further functionality would become available from 1 January 2027, followed by additional reporting requirements from 1 July 2027. Electronic invoicing is consequently developing beyond a digital substitute for paper invoices. It is becoming an important data infrastructure through which commercial transactions can be connected with VAT reporting and broader tax supervision.
Proposed additional reporting for certain transactions, including agricultural purchases and specific export-related information, would expand the amount of structured commercial data captured through the system. Companies therefore need to assess not only whether invoices can technically be submitted through SEF but also whether their underlying master data are accurate. Customer and supplier identification, VAT status, invoice dates, tax categories, exemptions, contract references and supporting documents increasingly form part of the digital control environment. A company may have correct accounting treatment while still generating inconsistencies if its commercial and tax systems use different classifications.
Corporate tax proposals strengthen anti-abuse rules
The proposed changes to corporate income tax include a general anti-abuse rule, adding another layer to Serbia’s corporate tax framework. Implementation would be staggered, with different provisions expected to apply from 2027 and 2028. A further set of measures connected with European Union alignment would become relevant upon Serbia’s eventual EU accession. The proposed general anti-abuse framework would give tax authorities broader scope to examine transactions according to their economic substance rather than solely their contractual form.
This is relevant to corporate groups using complex financing structures, related-party transactions, intellectual-property arrangements, holding companies and management-fee structures, as well as transactions involving tax incentives. Ordinary tax planning would not automatically become impermissible, but companies could increasingly need to demonstrate the commercial rationale and economic substance behind arrangements that produce significant tax benefits.
Documentation would consequently become an important component of corporate tax management. Board materials, investment models, intercompany agreements, transfer-pricing documentation and evidence supporting the commercial rationale of a structure could all form part of the relevant tax record.
Investment incentives face transitional considerations
The legislative package also contains transitional provisions intended to preserve access to certain existing tax incentives for companies that qualify before specified cut-off dates. This is relevant to investors planning manufacturing facilities, technology projects and other capital-intensive investments. Changes to eligibility requirements, duration or interaction with future EU-aligned rules can affect the economics of long-term investment projects.
Companies considering major investments can therefore assess scenarios under both the existing framework and the proposed future regime.
Projects approaching qualification thresholds may also need to determine whether investment or employment milestones completed before legislative cut-off dates affect eligibility. For investments whose economic lives may extend for 10 or 20 years, establishing which tax regime applies can be more significant than changes to individual headline rates.
Carbon taxation adds new requirements for energy-intensive sectors
The proposed greenhouse-gas taxation measures would introduce additional requirements for electricity generation and other emissions-intensive industries. Under the proposal, an investment-related credit for the electricity sector would explicitly constitute state aid, with the support limited to 20% of eligible decarbonisation investment costs and capped at 80% of the corresponding tax liability. The structure links tax treatment with investment in emissions reduction.
Separate transitional filing arrangements are envisaged for tax periods ending by 31 December 2026, with filings expected between 1 April and 31 May 2027. A parallel timetable is proposed for Serbia’s tax on imports of carbon-intensive products. For companies involved in electricity, steel, aluminium, cement, fertilisers and other emissions-intensive activities, this creates another reporting layer alongside existing financial, customs, environmental and energy-market obligations.
Businesses operating between Serbia and EU markets must also consider Serbia’s carbon reporting requirements alongside the European Union’s Carbon Border Adjustment Mechanism (CBAM). Although the systems are not identical, both increase the importance of reliable information on production, energy consumption and emissions.
ERP systems become central to tax controls
The proposed reforms have implications for enterprise software as much as for tax departments. Companies operating legacy ERP environments can maintain separate systems for accounting, invoicing, warehouse management, procurement, customs and tax reporting. As government reporting platforms become increasingly interconnected, differences between those systems can create compliance discrepancies.
An invoice carrying one tax classification in an ERP system, another in SEF and a third treatment in VAT reporting can produce a detectable inconsistency. The same issue can arise with dispatch documentation, inventory movements and fiscalisation records. Companies therefore face a need to treat 2027 tax readiness as an ERP and master-data project, examining whether one commercial transaction produces consistent information across all reporting systems.
That assessment requires mapping complete processes rather than checking tax returns alone. For sales transactions, this can cover the customer order, contract, delivery, dispatch note, invoice, SEF submission, accounting entry, payment, VAT treatment and tax return. Procurement processes require corresponding controls covering supplier onboarding, purchase orders, receipt of goods, invoice validation, input VAT and payment.
Higher minimum wages add to 2027 cost planning
The tax changes are being prepared alongside higher labour costs for Serbian employers. The government has adopted a minimum net labour price of RSD 405 per working hour for 2027, compared with RSD 371 in 2026, representing a 9.2% increase. An indicative monthly minimum wage has been set at approximately RSD 70,470, although the statutory parameter remains the hourly minimum and monthly amounts vary according to the number of working hours.
The financial impact can extend beyond employees directly paid at the statutory minimum. Companies in manufacturing, retail, logistics, hospitality, construction, security and cleaning can have several wage grades positioned relatively close to the minimum. An increase in the statutory floor can therefore create pressure to adjust salaries further up the wage structure. The resulting payroll impact may consequently exceed the direct 9.2% increase in the minimum hourly rate. Combined with spending on tax-system upgrades and compliance processes, this adds another variable to corporate budgeting for 2027.
Outsourcing does not remove responsibility for data quality
External accountants and software providers can support implementation, but outsourcing does not eliminate companies’ responsibility for the accuracy of their underlying commercial data. Software providers can establish technical interfaces and accountants can calculate tax liabilities, but companies remain responsible for determining whether their operational information correctly reflects actual transactions.
Digital tax administration increasingly connects tax compliance with operational processes. Product classifications can originate in sales systems, VAT categories during customer onboarding, dispatch discrepancies in logistics and missing documentation in procurement. Related-party issues can originate in treasury or group-management processes. Tax compliance is therefore increasingly becoming an enterprise-wide control framework rather than an isolated finance function.
Companies face a 2026 preparation window
The 24 August 2026 parliamentary session represents the next major legislative stage for the package. Until the proposals are adopted and formally published, individual provisions and implementation dates remain subject to change. The direction of the proposed framework is nevertheless centred on digital transaction reporting, interconnected tax databases, expanded electronic invoicing, stronger anti-abuse provisions and environmental taxation.
For companies, preparation therefore extends beyond monitoring tax rates. Internal systems need to be assessed for consistency between ERP platforms and regulatory reporting, existing investment incentives need to be reviewed, economically significant tax structures need appropriate documentation, and responsibility for digital tax data needs to be clearly assigned. The proposed changes would increasingly allow Serbia’s tax administration to compare information across invoices, VAT records, payments, dispatch data and corporate tax reporting at transaction level, making the quality and consistency of underlying corporate data a central component of tax compliance from 2027.
