Amendments to the green taxation legislation

The National Assembly of the Republic of Serbia adopted at its session held on 31 August 2026:

• the Law on Amendments to the Law on Greenhouse Gas Emissions Tax,  and
• the Law on Amendments to the Law on Tax on Carbon-Intensive Goods

Laws were published in the Official Gazette of the Republic of Serbia, no. 80/2026 as of 31 August 2026 and entered into force on 8 September 2026.

The most important changes are presented below.

Law on Greenhouse Gas Emissions Tax

Alignment of tax credit provisions with State aid rules

The Amendments to the Law prescribe that a tax credit for investments in measures and activities leading to the reduction of CO₂ equivalent emissions has the status of State aid. The tax credit may be used in combination with other forms of State aid or de minimis aid, but up to the level permitted under the State aid control rules.

Instead of the previous solution, under which the tax credit would be granted in the amount of 20% of invested financial resources, it is now prescribed that the tax credit is granted in the amount of up to 20% of eligible investment costs, in accordance with State aid regulations.

The taxpayer is not entitled to the tax credit if:

• it has been ordered to repay State aid or de minimis aid;
• it is in difficulty, within the meaning of State aid control rules.

Taxpayers in difficulty may exercise the right to the tax credit only if State aid regulations explicitly allow the granting of aid to such taxpayers.

For the purpose of controlling the amount of aid and ensuring compliance with State aid control rules, a new obligation is introduced to submit, together with the tax return, a statement confirming whether State aid or de minimis aid has already been used for the relevant investment.

Special deadline for filing of tax returns

The Amendments to the Law introduce the exception for filing tax returns for specific tax periods. Specifically, the tax return for 2026, as well as the tax return in the case of discontinuation of business activities by 31 March 2027, are to be submitted in the period from 1 April to 31 May 2027.
