New capital gains tax on financial assets was submitted to Parliament in December 2025. This new capital gains tax will retroactively enter into force as from 1 January 2026, once the new legislation is adopted and published in the Belgian Official State Gazette. On the below link you can find a detailed outline of the new capital gains tax regime and an analysis of its impact on estate planning, long-term incentives, management incentive plans, and the financial services sector. It should be noted that during the parliamentary legislative process the draft bill may still be subject to amendments. It is expected that the bill will be adopted later in January or February 2026.
