Assumptions

Tax year: 2026

Last updated: 2026-10-19

  • Belgium uses a simplified annual employee payroll model in this dataset rather than the full official withholding engine.
  • ONSS / RSZ is modeled at 13.07% on gross salary with no ceiling in this MVP.
  • Federal income tax is estimated with annual progressive brackets of 25%, 40%, 45%, and 50%, less the bracket tax on the tax-free allowance.
  • The configured base tax-free allowance for the 2026 estimate is EUR 11,550.
  • For a married household, the model transfers enough professional income to bring the lower-income spouse to 30% of combined professional income, capped at EUR 11,780; it applies the benefit only when this lowers estimated household federal tax.
  • Payroll-withholding parameters are versioned separately: the legacy 2026 set applies through October 31 and the September 27 royal-decree set applies to remuneration paid from November 1. These parameters do not replace the annual income-tax calculation.
  • Dependent children increase the estimated tax-free allowance by EUR 2,130 for one child, EUR 5,130 for two, EUR 11,440 for three, EUR 18,510 for four, and EUR 7,070 per additional child; special family circumstances are excluded.
  • Municipal tax is modeled as a user-selected percentage between 0% and 9% applied on top of the post-reduction federal income tax.
  • The special social-security contribution is approximated with a simple monthly bracket scale between EUR 0 and EUR 60.
  • The optional expat comparison estimates a separate employer-expense reimbursement up to 35% of gross remuneration when annual remuneration is at least EUR 70,000; it is not an automatic tax-free salary conversion. The income-tax saving compares that reimbursement with the same extra payment treated as taxable; ONSS and special social-security contributions on salary are not reduced.

Comparison Topics

What you can compare before acting on a salary number

A country salary calculator is most useful when it is paired with context. In this section, readers can move from a headline gross number to practical questions about net income, payroll timing, special tax regimes, and contract trade-offs.

Methodology

Why salary estimates differ from one person to another

The same gross salary can lead to different net outcomes depending on tax residence, marital status, dependants, region, payment schedule, and local special rules. That is why these pages combine calculators with articles instead of showing a single generic answer.

Use these routes as a practical decision tool, not as formal tax advice. For any important move, contract decision, or relocation plan, readers should validate assumptions against the local authority guidance shown in the calculator and article sources.
