The Official Gazette of the Republic of Serbia, No. 27, dated 27 March 2026, published amendments to a set of tax rulebooks, with significant practical implications, primarily in the areas of value added tax (VAT), e-invoicing and electronic filing of tax returns.
Rulebook on Amendments to the Rulebook on Value Added Tax:
- The most extensive amendments relate to the rules governing changes in the tax base, including both increases and decreases thereof, as well as the tax treatment of the cancellation of documents and the adjustment of input VAT.
- The amendments regulate in particular: the point in time at which a change in the tax base is recognized for the relevant tax period; the document on increase and the document on decrease; the conditions for reducing output VAT; the adjustment of input VAT deduction; the treatment of the cancellation of invoices, advance invoices, increase and decrease documents, as well as internal invoices; the content and delivery of the recipient’s notice regarding input VAT; and the rules governing the preparation of internal invoices.
- Particular importance should be attached to the provisions specifying the conditions under which a taxpayer may reduce output VAT where the tax base is subsequently reduced, as well as the obligation of the recipient to adjust the input VAT deduction.
- From a practical perspective, the clarified deadlines are also significant, as several provisions stipulate that the relevant conditions must be fulfilled no later than the day preceding the filing of the tax return, and in any event no later than the 10th day of the calendar month following the relevant tax period, or, in certain cases, no later than the 12th day of the following month.
- These amendments shall apply starting from the April 2026 tax period, or the April–June 2026 tax period, as applicable.
Rulebook on Amendments to the Rulebook on Electronic Invoicing:
- The amendments to this Rulebook further align the e-invoicing system rules with the VAT rules and provide more detailed guidance on the manner of recording data within the e-invoicing system.
- The most important changes concern: advance payments, in particular where an advance is received on the date of supply; the presentation of data in Serbian dinars and in foreign currency; the introduction of other documents related to transactions, including the preliminary VAT return and the recipient’s notice regarding input VAT; the content of the aggregate VAT ledger; the content of the individual VAT ledger – internal invoice; the rules governing corrections and cancellations of ledgers; electronic VAT recording in situations where an electronic invoice has not been issued within the prescribed deadline; and the integration of the e-invoicing system with the electronic dispatch note system and the relevant information systems of the Serbian Tax Administration and the Customs Administration.
- It is particularly important that the statuses of ledgers have been more precisely regulated, namely: recorded, corrected and cancelled, as well as the cases in which a correction is to be made and those in which cancellation applies.
- These amendments shall apply to tax periods commencing after 31 March 2026.
Rulebook on Amendments to the Rulebook on the Tax Return for Annual Personal Income Tax:
- The most important amendment is the replacement of the existing PP GPDG form with a new tax return form for assessed annual personal income tax, which means that taxpayers liable to annual personal income tax will be required to use the newly prescribed form when filing their next return.
Rulebook on Amendments to the Rulebook on Filing Tax Returns Electronically:
- The amendments to this Rulebook regulate in greater detail the content of an electronic tax return and the data to be entered therein.
- More specifically, the following are regulated in greater detail: the types of tax returns; the designations of the tax period or accounting period; data on the date of occurrence, due date and payment date of the tax liability; the types of amendments to tax returns, including the cancellation of returns; data on the taxpayer, tax payer and the person submitting the return; data on the tax proxy; supplementary data relating to the return and the type of tax liability; attachments to the return; and the circle of persons authorized to file tax returns electronically.
- The application of these amendments is linked to the date of implementation of the relevant tax returns in the appropriate information system of the Serbian Tax Administration.
