After Arizona’s coalition agreement in January and policy statements in March, several new tax measures were introduced.
A first package of tax measures is included in the Program law, which was approved by Parliament on July 18, 2025 and published in the Belgian official Gazette of July 29, 2025 (NL / FR).
In our previous Tax Alert, we provided an overview of the tax measures contained in the Program Law. For further detailed information on each new measure, please refer to that alert.
The alert was prepared in accordance with the draft legislation submitted to and approved by Parliament. However, delays encountered during the legislative process affected the initial implementation timeline. While most provisions were originally planned to take effect on July 1, 2025, these delays led to a revision of the effective date, which now aligns with publication in the Belgian Official Gazette on July 29, 2025, unless otherwise stipulated.
The following provides an overview of the tax measures, along with their corresponding revised dates of entry into force.
