Dutch Tax Calculator (Box 1 Income, Simplified)
Use this calculator to estimate annual tax, effective tax rate, and net monthly income in the Netherlands.
This is an educational estimator using simplified Dutch Box 1 rates and tax credits. It does not replace advice from a tax adviser or the Belastingdienst.
How this Dutch tax calculator helps
Many people search for a quick way to convert gross salary to net salary in the Netherlands. This page gives you a practical estimate in seconds. You can compare job offers, test the impact of deductions, and see how the 30% ruling changes your taxable income.
The tool is designed for clarity: enter your annual gross income, choose your tax year, and optionally include deductions or pension contributions. The result shows your estimated annual tax, monthly net income, and effective tax rate.
How Dutch income tax works (simplified)
1) Progressive tax brackets
The Dutch system taxes income progressively. Lower portions of income are taxed at lower rates, and higher portions are taxed at higher rates. In this simplified calculator, we focus on Box 1 employment income.
2) Tax credits reduce tax payable
Two important credits are included in this model:
- General tax credit (algemene heffingskorting) — usually highest at lower incomes, then gradually reduced.
- Labour tax credit (arbeidskorting) — linked to employment income and phased down at higher income levels.
3) AOW and expat scenarios
If you have reached AOW age, the first band in this estimator uses a reduced first rate. If the 30% ruling applies, this calculator taxes only 70% of the adjusted income base (simplified approach).
What is included in this calculator
- Year selection (2024, 2025, 2026 assumptions)
- Progressive Box 1 tax rate structure
- General tax credit and labour tax credit estimates
- Optional deduction inputs
- Optional holiday allowance inclusion
- Optional AOW and 30% ruling toggles
What is not included
Real-world tax returns can include additional rules and exceptions. This estimator does not fully model every component (for example: exact payroll wage tax tables, all allowances, partner effects, Box 2 and Box 3 items, healthcare allowance, municipal taxes, and detailed pension arrangements).
Example: quick gross-to-net check
Suppose your gross annual income is €60,000 and you include an 8% holiday allowance. Your salary base for this estimator becomes €64,800 before deductions. After applying progressive tax and estimated credits, the calculator shows your expected annual tax and resulting monthly net amount. This is useful for negotiation and budgeting.
Tips to reduce tax pressure legally
Review deductible items
If you have eligible deductible costs, include them in your annual planning. Even modest deductions can improve your final net position.
Understand pension contributions
Pension contributions can influence taxable income and long-term retirement outcomes. It is often worth comparing short-term net pay versus long-term savings growth.
Run multiple scenarios
Try different combinations in the calculator:
- With and without holiday allowance
- Current salary versus proposed salary
- Different deduction levels
- 30% ruling on/off for expat planning
Frequently asked questions

No. It is an independent educational tool to help you estimate Dutch income tax and net salary.
Can I use this for freelancers or business owners?
You can use it as a rough starting point for Box 1 income, but self-employed taxes include extra rules and deductions not fully represented here.
Why does my payroll slip differ?
Payroll systems may apply detailed month-by-month tables and employer-specific setups. Final annual tax can differ from monthly withholding.
