Summary
The Netherlands uses a combined income tax and social insurance premium system for Box 1 income (employment and home ownership). Rather than separating income tax from social contributions, the Dutch system bundles them into combined bracket rates. Employees under the state pension age (AOW-leeftijd) pay social premiums (AOW, Anw, Wlz) embedded in the first two brackets. Two tax credits — the algemene heffingskorting (general tax credit) and arbeidskorting (employed person’s tax credit) — significantly reduce the effective tax burden for low and middle incomes.
How it works
Dutch take-home pay is calculated as:
Gross salary - Combined tax and premiums + Tax credits = Net pay
- Combined income tax and social premiums (Box 1) — three brackets with rates that include both income tax and national insurance premiums (AOW, Anw, Wlz) in the lower brackets
- Algemene heffingskorting — a general tax credit that phases out as income increases
- Arbeidskorting — an employed person’s tax credit that increases with income up to a maximum, then phases out at higher incomes
Social Premiums Embedded in Brackets
For taxpayers below the AOW age, the first bracket rate includes:
| Premium | Rate |
|---|---|
| AOW (state pension) | 17.90% |
| Anw (surviving dependants) | 0.10% |
| Wlz (long-term care) | 9.65% |
| Total social premiums | 27.65% |
These premiums are only levied on income in the first bracket (up to EUR 38,441). Income tax is layered on top, producing the combined rates shown below.
Income Tax Bands — Box 1 (2025)
For taxpayers below the AOW age:
| Taxable income | Combined rate | Of which tax | Of which premiums |
|---|---|---|---|
| EUR 0 — EUR 38,441 | 35.82% | 8.17% | 27.65% |
| EUR 38,442 — EUR 76,817 | 37.48% | 37.48% | 0% |
| Above EUR 76,817 | 49.50% | 49.50% | 0% |
Taxpayers above the AOW age pay lower rates in the first bracket because AOW premiums no longer apply.
Tax Credits (Heffingskortingen, 2025)
Algemene Heffingskorting (General Tax Credit)
| Taxable income | Credit amount |
|---|---|
| Up to EUR 24,813 | EUR 3,362 (maximum) |
| EUR 24,813 — EUR 76,817 | Reduces by 6.337% of income above EUR 24,813 |
| Above EUR 76,817 | EUR 0 |
Arbeidskorting (Employed Person’s Tax Credit)
| Employment income | Credit amount |
|---|---|
| Up to EUR 11,491 | 8.231% of income |
| EUR 11,491 — EUR 24,821 | EUR 946 + 29.861% of income above EUR 11,491 |
| EUR 24,821 — EUR 39,958 | EUR 4,926 + 3.085% of income above EUR 24,821 |
| EUR 39,958 — EUR 124,935 | EUR 5,393 (maximum) |
| Above EUR 124,935 | EUR 5,393 - 6.51% of income above EUR 124,935 |
The arbeidskorting is only available to those with employment income (not to pensioners or benefit recipients for this portion).
Worked Example
For a gross salary of EUR 45,000 (single, below AOW age, no mortgage interest deduction):
- Combined tax and premiums:
- On EUR 0 — EUR 38,441 at 35.82% = EUR 13,766
- On EUR 38,442 — EUR 45,000 at 37.48% = EUR 6,559 x 37.48% = EUR 2,458
- Gross tax: EUR 16,224
- Algemene heffingskorting:
- Income EUR 45,000 > EUR 24,813, so credit = EUR 3,362 - (EUR 45,000 - EUR 24,813) x 6.337%
- = EUR 3,362 - EUR 1,279 = EUR 2,083
- Arbeidskorting:
- Income EUR 45,000 falls in the EUR 39,958 — EUR 124,935 band
- = EUR 5,393 (maximum)
- Total tax credits: EUR 2,083 + EUR 5,393 = EUR 7,476
- Net tax: EUR 16,224 - EUR 7,476 = EUR 8,748
- Take-home pay: EUR 45,000 - EUR 8,748 = ~EUR 36,252/year (~EUR 3,021/month)
Assumptions and Limitations
- 2025 rates only — uses rates and credits for the 2025 tax year
- Below AOW age — uses the higher combined rates that include social premiums. Pensioners pay lower rates
- Box 1 income only — employment income. Does not model Box 2 (substantial shareholdings) or Box 3 (savings and investments)
- No mortgage interest deduction — hypotheekrenteaftrek can significantly reduce Box 1 taxable income for homeowners
- Single earner — does not model the inkomensafhankelijke combinatiekorting (income-dependent combination credit) for parents
- Standard premiums — does not model the nominal health insurance premium (Zvw), which is approximately EUR 1,900/year and paid separately by the employee (not deducted from salary but mandated)
- No 30% ruling — the 30% ruling for expatriates (which exempts 30% of salary from tax) is not applied in this example
