The short answer
On a €90,000 salary (€7,500 gross a month) you keep about €4,859 every month. Every extra euro you earn is taxed at 49.5% plus the loss of tax credits, so a raise is worth less net than it looks.
How the tax is calculated
- 1Gross salary €90,000 + 8% holiday allowance = €97,200
Holiday allowance is taxed as normal income, so it is part of the yearly calculation.
- 2Income tax and national insurance: €38,046
Box 1 rates for 2026: 35.8% up to €38,883, 37.6% up to €78,426, 49.5% above.
- 3Minus general tax credit: €0
The algemene heffingskorting shrinks as income rises.
- 4Minus labour tax credit: €2,325
The arbeidskorting for people who work; it also phases out at higher incomes.
- 5Tax you actually pay: €35,721 a year
That is 36.7% of your gross pay, your effective tax rate.

What it means in practice
Many landlords ask for a gross income of 3 to 4 times the rent. On €7,500 gross a month that points to rents up to about €2,143.
At this income you are usually above the limits for healthcare allowance; childcare allowance can still apply.
Most employers deduct a pension contribution before tax, which lowers both your tax and your net pay. Your payslip will show it.
Tax is personal in the Netherlands: a partner's income doesn't change your Box 1 tax, but fiscal partnership lets you split deductions.
Assumptions: 2026 rates, under AOW age, no pension contribution, no other income. Your payslip uses monthly tables, so individual months can differ slightly; the yearly total is settled in your tax return.
