Three new rulebooks have been published in the Official Gazette of the Republic of Serbia, No. 65/2026, establishing the implementing framework for Serbia’s new tax legislation in the field of climate policy and carbon taxation, namely the Law on the Tax on Greenhouse Gas (GHG) Emissions and the Law on the Tax on Imports of Carbon-Intensive Products.
For the first time, these rulebooks provide detailed regulation of:
- The content and filing procedure for tax returns relating to greenhouse gas (GHG) emissions;
- The content and filing procedure for tax returns relating to the import of carbon-intensive products;
- The procedure for claiming tax credits, the supporting documentation required, and the methodology for calculating such tax credits;
- The prescribed forms and records that taxpayers are required to maintain; and
- The exchange of information between the Customs Administration and the Tax Administration for the purpose of determining tax liabilities.
Of particular importance is the fact that these rulebooks establish the administrative framework necessary for the implementation of the new legislation—from tax return forms and emissions records to documentation on investments in emission reduction projects, as well as evidence required to claim a tax credit where a carbon price has already been paid in the country of origin of the imported products.
For companies operating facilities with significant greenhouse gas (GHG) emissions or importing carbon-intensive products, compliance will require more than merely fulfilling new tax obligations. Businesses will also need to implement appropriate internal procedures for collecting technical data, maintaining statutory records, and ensuring effective coordination among tax, finance, customs, technical, and ESG teams.
With the adoption of these rulebooks, Serbia has effectively completed the regulatory framework necessary for the practical implementation of its new climate-related tax instruments. These measures represent a significant step towards aligning Serbian legislation with the European carbon pricing framework and the Carbon Border Adjustment Mechanism (CBAM), which seeks to ensure that imported products bear a carbon cost comparable to that imposed on domestic producers.
