Frequently asked questions

At EUR 100,000 a year you pay EUR 46,345 in total for income year 2026, including ONSS at 13.07%, an effective rate of 46.3%. That leaves EUR 53,655 net, or EUR 4,471 a month.

Is the exempt amount included?

Yes. The exempt amount of EUR 11,180 is applied as a tax reduction worth EUR 2,795, which is 25% of it, rather than as a deduction from income. That is how Belgian tax actually grants it.

What is not included?

The werkbonus and the tax credit for low activity income are not modelled, so lower salaries show more tax here than would actually be paid. The special social security contribution is also excluded, which runs the other way. Increases in the exempt amount for dependants are not applied.
