How is net salary calculated for Belgium?

For Belgium, we apply the official tax brackets in force and social contributions to the gross salary. The gross is entered in EUR and converted to EUR at the ECB reference rate before calculation.

What assumptions does this comparison use?

Both calculations assume a single filer with no children, no special deductions or tax regimes, and standard filing options. For Swiss cantons, the main municipality is used with age group 35-44, no church tax, and no Pillar 3a contribution. For US states, the standard deduction is applied.

Are the amounts in the same currency?

Each side shows amounts in the local currency of that jurisdiction (EUR for Belgium, CHF for Geneva). The input gross salary is in EUR, converted to each local currency at ECB reference rates. The effective rate comparison is currency-independent.

Can I change the salary or filing status?

The tool above lets you enter any gross salary in EUR and choose from five household configurations: single, married, or married with 1-3 children. The comparison updates in real time.

How often are tax rates updated?

Tax brackets and social contribution rates reflect the tax year stated in the source line below the tables. Exchange rates are updated regularly from ECB reference rates. We update rates whenever official sources publish new figures.
