The short version

Belgium taxes salaries at 25% to 50% plus about 7% municipal surcharge, after 13.07% social security with no ceiling, which makes it one of the most expensive countries in Europe for employees. From 2026 it also taxes financial gains at 10% above EUR 10,000 a year. Recruited expats earning EUR 70,000 or more can receive 35% of their pay tax-free.

01 · The system

How Belgium taxes individuals

Belgium has some of the highest taxes on salaries in Europe and, until 2026, some of the lightest on investment gains. Employees pay 13.07% social security with no ceiling, then federal income tax at 25% to 50%, then a municipal surcharge of about 7% of that tax. The Arizona government reforms change both sides: a higher tax-free sum on salaries, and a new tax on capital gains from 2026.

Belgium used to tax work like a high-tax country and gains like a tax haven. From 2026 it taxes both, just not equally.
05 · Expats and directors

The expat regime and company directors

Since 2025 recruited expats earning at least EUR 70,000 can receive 35% of their pay as a tax-free cost allowance, without the former EUR 90,000 cap, for five years plus three. Company directors who want their company to keep the reduced 20% corporate rate must pay themselves at least EUR 45,000, rising to EUR 50,000 from 2026 under the reform.

For many Belgian residents working in Luxembourg the comparison is direct: the salary is taxed in Luxembourg, often at a lower rate, as long as the 34-day limit on work outside Luxembourg is respected.
