How capital gains tax works in Belgium
Since 1 January 2026, Belgium taxes gains on financial assets — shares, bonds, funds, derivatives, qualifying insurance, crypto and gold — through a solidarity contribution. Net yearly gains above EUR 10,000 pay 10%.
Gains built before 2026 stay exempt. Listed assets use 31 December 2025 closing prices as baseline, and historic cost may be used if higher until 2030. Gifts and inheritances are not taxable events.
Stakes of 20% or more get EUR 1 million exempt per five-year backpack, then 1.25% to 10% by slice. Sales to your own controlled company pay 33% flat, and speculative deals keep the old 33% too.

Watch out for
- Losses only offset gains in the same category and year. There is no carry-forward, so a loss in January and a gain in December still net, but last year's loss never returns.
- Belgian intermediaries withhold 10% with opt-out. Foreign accounts and crypto self-report, which puts the calculation burden on the investor.
- The EUR 1,000 first-tranche carry-forward is capped at EUR 15,000 over five years. Small investors should track unused room yearly.
- Property follows separate short-term rules, not the solidarity regime. Quick flips of buildings face 16.5% or 33% under their own clock.
