How corporate tax works in Belgium
Belgium taxes resident companies on worldwide income at 25%. Small companies pay 20% on the first EUR 100,000 of profit if they meet size, pay and activity conditions.
Dividends and capital gains on holdings of 10% or EUR 2.5 million held a year are fully deductible or exempt. From 2026 the value route needs the stake to be a financial fixed asset.
Groups above EUR 750 million turnover face the 15% Pillar Two minimum through Belgian IIR, domestic top-up and UTPR rules. An 85% innovation deduction shelters qualifying IP income near 3.75% effective.

Watch out for
- The 20% SME rate has teeth in its conditions. Minimum director pay of EUR 50,000, small-company status and non-financial activity must all hold, or the whole profit pays 25%.
- Underpaid advance payments trigger a 6.75% surcharge for 2026. Quarterly prepayments need calendar discipline, not year-end catch-up.
- The participation exemption is generous but fenced. One-year holding, subject-to-tax tests and the 2026 fixed-asset rule all need checking before distributing.
- Salary-heavy founders face the personal side too. A 25% company rate beside 50%-plus salary tax makes dividend and reserve planning central.
