Method and scope
2026 Dutch resident, age 66 or younger throughout the year, subject to full national-insurance contributions. Applies the combined Box 1 rates 35.75%, 37.56% and 49.5%. The first band includes national-insurance premiums. General/employment/other tax credits, Box 2/3, AOW-age rates, the 30% facility, health-insurance premiums, employer deductions and special deduction-rate adjustments are excluded. Enter already-determined taxable Box 1 income, not gross wages. Calculations retain cents; whole-euro assessment rounding can differ. This is tax plus national insurance before credits, not take-home pay.

Compare one assumption at a time
Compare the change in estimated tax with the change in entered income. The effective rate on the whole income and the tax on an additional amount are different measures. Only the supported tax components are shown; this table does not expand the scope into a full return or payslip. These fictional scenarios use the starting inputs printed above, not your current entries in the interactive calculator.
| Annual taxable Box 1 income after deductions | Box 1 tax + national insurance before credits | Interpretation |
|---|---|---|
| € 54.000 | € 19.578,62 | One changed input |
| € 60.000 | € 21.832,22 | Starting example |
| € 66.000 | € 24.085,82 | One changed input |
Is the result a full tax bill or only the supported component?
Box 1 includes the stated national-insurance treatment before credits; it does not calculate every part of a Dutch return. Lijfrente accumulation requires verified eligible contribution room, which the tool does not derive from salary. A higher projected balance does not prove a larger deductible contribution is permitted.
To reproduce the table, reset the calculator, change only the named input and compare the result and any warning. Record the assumptions with your result. See worked planning examples and our calculation and correction process.
