Overview
On 27 March 2026 (published in the Official Gazette No. 30/2026), the Serbian Ministry of Finance enacted amendments and supplements to two important tax rulebooks:
- the Rulebook on Value Added Tax (“VAT Rulebook”), and
- the Rulebook on Electronic Invoicing (“E-Invoicing Rulebook”).
Rulebooks will apply starting from the April 2026 tax period.
Amendments and supplements to these rulebooks have largely been made in response to the latest amendments to the VAT Law and the Law on Electronic Invoicing, which took place at the end of last year.
VAT Rulebook – amendments, supplements and key changes
- Rules related to tax base (e.g. the estimation of the tax base in cases where the amount of the tax base is not known on the date the tax liability arises, determining the tax base in cases of exchange of goods and services where part of the consideration is settled through a monetary payment, etc).
- Rules related to the increase and decrease of tax base (in short, from now on, in the case of the return of goods on any grounds, there is a change in the tax base).
- Obligation to create the internal invoice for the increase in the VAT base.
- Defining the tax period in which the calculated VAT should be decreased in the event of adjustments to the tax base.
- Tax period in which the correction of the input VAT deduction should be done.
- Adjustment of input VAT deduction based on the cancellation of invoices and other documents.
- Delivery of a notification electronically or in any other form regarding the adjustment of input VAT deduction.
- Requirement to issue an invoice in respect of advance payments, with an exception where no invoice is required.
- Rules for the issuance of the internal invoice.
- The manner of reporting invoice details in cases where payment is made in a foreign currency.
- Additional rules regarding the cancellation of the invoice and documents for a decrease in the VAT base.
E-Invoicing Rulebook – amendments, supplements and key changes
- Advance invoices may be issued even when payment is received on the date of supply of goods or services.
- Method of presenting unit price data in electronic invoices for goods and services, depending on whether payment is made wholly or partially in Serbian dinar (RSD) or entirely in a foreign currency.
- Requirement to report negative values for tax category N and positive values for other tax categories.
- Further specification of the content of individual VAT records.
- Correction of individual and summary VAT records in cases of incorrectly or incompletely reported data.
- Electronic recording of VAT in summary records for VAT payers who have not issued an e-invoice.
- Further definition of the status of the individual and summary records.
- Cases in which there is no obligation to record input VAT.
- Integration of the E-Invoicing system with the electronic dispatch note system, as well as further integration with the information systems of the Tax Administration and Customs Administration.
Conclusion
The latest amendments to the VAT and E-Invoicing Rulebooks further develop and align Serbia’s tax framework, as another step towards further digitalisation (including the earlier-announced introduction of preliminary VAT return submitted via SEF). Businesses are expected to take necessary steps to align their internal processes and systems to ensure compliance from the April 2026 tax period onward.
