Residency
Residency trigger

Non-resident treatment
Cross-border workers follow EU coordination rules or bilateral treaties; the employer's much larger share (≈25%+) is outside this page.
Notes
- No ceiling means high salaries keep paying 13.07% forever — combined with the 50% bracket this drives Belgium's famous ~59%+ marginal rates.
- Blue-collar workers' contributions are computed on 108% of gross pay (an old holiday-pay convention).
- A 'work bonus' reduction cuts employee contributions at low wages — the 13.07% is the standard, not the minimum-wage, reality.
- The self-employed pay into their own scheme with lower pension accrual — many add voluntary supplementary pensions, which are deductible.
