Loss utilization
Belgium
Losses may be carried forward indefinitely, but their use in a given tax year is limited to EUR1 million plus 70 percent of the taxable basis in excess of EUR1 million. Any carried-forward tax losses that cannot be used due to this limitation may be further carried forward indefinitely. The remaining 30 percent of the taxable basis in excess of EUR1 million will be subject to normal corporate income tax rates.
As of income year 2023 (assessment year 2024), the 70 percent threshold was reduced to 40 percent to increase the minimal taxable basis to 60 percent instead of 30 percent. This measure was temporary, as regulators intended to abolish this measure as soon as the global minimum tax rules (OECD Pillar Two) enter into force in Belgium.
At the end of 2023, Belgium implemented the Council Directive (EU) 2022/2523 of December 15, 2022, ensuring a global minimum level of taxation for groups of multinational enterprises and large domestic groups in the European Union. These rules introduce a coordinated system to ensure that large groups with a consolidated revenue exceeding EUR750 million for at least 2 of the 4 previous years, are subject to a minimum effective tax rate of 15 percent. The global minimum tax rules in Belgium will be applicable to financial years beginning on or after December 31, 2023. With the introduction of the global minimum taxation rules, the 40 percent threshold was increased back to 70 percent as of assessment year 2025.
