Understanding Netherlands tax deductions 2025/2026 is essential for anyone living, working, or investing in the Netherlands. The Dutch tax system offers a range of income tax allowances and relief measures that can significantly reduce your overall tax burden — but only if you know what's available and how to claim them.

Whether you're a Dutch resident, an expat benefiting from the 30% ruling, or a non-resident earning income in the Netherlands, this guide breaks down every major deduction and allowance you need to know for the 2025/2026 tax year. Use our Netherlands Income Tax Calculator to see how these deductions affect your personal tax liability.

How the Netherlands Income Tax System Works in 2025/2026

Before diving into specific deductions, it's important to understand the structure of the Dutch income tax system. The Netherlands taxes income across three separate "boxes":

  • Box 1 – Income from work and home: Employment income, business profits, pensions, and the deemed rental value of your primary residence. This is subject to progressive tax rates.
  • Box 2 – Income from substantial interest: Dividends and capital gains from a shareholding of 5% or more in a company.
  • Box 3 – Income from savings and investments: A deemed return on net assets (savings, investments, and other assets minus debts) above a tax-free threshold.

Most deductions and allowances apply to Box 1 income. For 2025, the progressive Box 1 tax rates are:

Taxable Income (EUR) Tax Rate
Up to €38,441 35.82%
€38,441 – €76,817 37.48%
Above €76,817 49.50%

These rates include social security contributions (premiums for AOW, ANW, and WLZ) in the first bracket. The tax credits and deductions described below are applied against tax calculated at these rates.

Key Tax Credits (Heffingskortingen) for 2025/2026

The Netherlands uses a system of tax credits — amounts directly subtracted from your calculated tax — rather than only deductions from taxable income. These credits are among the most valuable tools for Netherlands tax relief.

General Tax Credit (Algemene Heffingskorting)

Every Dutch taxpayer is entitled to the general tax credit. For 2025, the maximum credit is approximately €3,362 for incomes up to around €24,813. The credit phases out as income rises and reaches zero at incomes above approximately €75,518.

Key points:

  • The credit is automatically applied by your employer or pension provider through payroll.
  • Non-residents may receive a reduced or pro-rated general tax credit depending on their qualifying non-resident taxpayer status.
  • Fiscal partners can transfer unused general tax credits to each other in certain circumstances.

Labour Tax Credit (Arbeidskorting)

If you earn employment income or profits from a business, you qualify for the labour tax credit. For 2025, this credit can reach a maximum of approximately €5,599 and phases out for incomes above approximately €39,958, declining to zero for incomes above roughly €124,935.

This is one of the most significant income tax allowances in the Netherlands and is designed to incentivize workforce participation.

Elderly Tax Credits

Taxpayers who have reached the Dutch state retirement age (AOW age) may qualify for:

  • Elderly person's tax credit (Ouderenkorting): Up to approximately €2,010 for 2025, phasing out at higher incomes.
  • Single elderly person's tax credit (Alleenstaande ouderenkorting): An additional credit of approximately €524 for single pensioners receiving AOW.

Income-Dependent Combination Credit (IACK)

Working parents with a child under 12 can claim the income-dependent combination credit. For 2025, this credit can amount to approximately €2,950. You must earn above a minimum income threshold and be the least-earning parent (or a single parent) to qualify.

Deductions from Taxable Income in Box 1

Beyond tax credits, the Dutch system allows several deductions directly from your taxable income. These reduce the amount of income subject to tax.

Mortgage Interest Deduction (Hypotheekrenteaftrek)

The mortgage interest deduction remains one of the most important Netherlands tax deductions for homeowners. If you own and live in your primary residence, you can deduct the interest paid on your mortgage loan from your Box 1 income.

Key rules for 2025/2026:

  • The deduction applies only to your primary residence (eigen woning), not investment properties.
  • The maximum deduction rate is capped at 36.97% for 2025 — meaning high earners cannot deduct mortgage interest at the top 49.50% rate. This cap has been gradually reduced over recent years.
  • Mortgages must be annuity or linear repayment mortgages taken out after January 1, 2013, to qualify. Interest-only mortgages from before this date are grandfathered in under transitional rules.
  • The maximum mortgage term for deductibility is 30 years.
  • You must also add back the eigenwoningforfait (deemed rental value), which is a small percentage of your home's WOZ value added to your taxable income. For 2025, this is approximately 0.35% for homes valued between €75,000 and €1,310,000.

Practical Example: If your home has a WOZ value of €350,000 and you pay €8,000 in annual mortgage interest, your net deduction would be approximately €8,000 minus the eigenwoningforfait (€350,000 × 0.35% = €1,225), resulting in a net deductible amount of around €6,775.

Charitable Donations (Giftenaftrek)

Donations to qualifying Dutch or EU/EEA charitable organizations (ANBIs) and cultural institutions (cultural ANBIs) are deductible:

  • Periodic gifts: Fully deductible without a threshold, provided they are documented in a written agreement for at least five years.
  • One-time gifts: Deductible only to the extent they exceed a threshold of 1% of your "threshold income" (drempelinkomen), with a minimum of €60. The maximum deduction is 10% of your threshold income.
  • Cultural ANBI multiplier: Donations to qualifying cultural institutions receive a 1.25x multiplier (i.e., €100 donated counts as €125 for deduction purposes), up to a maximum bonus of €1,250.

Medical Expenses (Specifieke Zorgkosten)

Certain unreimbursed medical expenses can be deducted if they exceed an income-dependent threshold. Qualifying expenses include:

  • Prescribed medication and medical aids
  • Travel costs to medical facilities
  • Dietary costs prescribed by a physician (standardized amounts)
  • Extra clothing and bedding costs due to illness or disability
  • Costs of home modifications for disabled individuals

Expenses already covered by health insurance or other reimbursements cannot be deducted. The threshold for 2025 is typically between 1.65% and 10% of threshold income, depending on income level.

Study Costs and Personal Development

As of recent years, the traditional study cost deduction has been replaced by the STAP budget (Stimulans van de ArbeidsmarktPositie), a government subsidy for training and education. The STAP budget provides up to €1,000 for approved training courses. This is not a tax deduction but a direct subsidy. Check current availability, as the program's continuation may vary year to year.

Spousal Maintenance (Alimentatie)

Alimony or spousal maintenance payments to an ex-partner are fully deductible from your taxable income. Child support (kinderalimentatie), however, is not deductible.

Annuity Premiums and Pension Shortfalls (Lijfrentepremie)

If you have a pension shortfall — meaning your accumulated pension falls below the recommended level — you can deduct contributions to qualifying annuity products (lijfrente). The maximum deductible amount depends on your "annual margin" (jaarruimte) and any unused deduction space from previous years (reserveringsruimte).

For 2025, the annual margin calculation allows deductions of up to approximately €15,475 for annual contributions, while unused space from up to seven prior years can be carried forward.

The 30% Ruling for Expats

The 30% ruling (30%-regeling) is the Netherlands' most well-known tax benefit for international workers. It allows qualifying expats to receive up to 30% of their gross salary tax-free, intended as a flat-rate reimbursement for extraterritorial costs incurred when relocating to the Netherlands.

Eligibility Requirements

  • You must have been recruited from abroad or transferred to the Netherlands by your employer.
  • You must have specific expertise that is scarce or unavailable in the Dutch labor market.
  • You must have lived more than 150 kilometers from the Dutch border for at least 16 of the 24 months before starting work in the Netherlands.
  • A minimum salary requirement applies (approximately €46,107 gross per year for 2025, or approximately €35,048 for employees under 30 with a qualifying Dutch Master's degree).

Key Changes for 2025/2026

The Dutch government has implemented significant changes to the 30% ruling:

  • Step-down structure: For new applications from 2024 onward, the ruling follows a phased reduction: 30% in the first 20 months, 20% for the next 20 months, and 10% for the final 20 months, totaling a maximum of 5 years.
  • Salary cap: The tax-free allowance is capped at the "Balkenende norm" (approximately €233,000 for 2025). For employees earning above this threshold, only the portion up to the cap qualifies for the 30% exemption.
  • Grandfathering: Employees who were already benefiting from the 30% ruling before December 31, 2023, may be subject to transitional rules that preserve the original 30% rate for the remaining duration.

This ruling represents substantial Netherlands tax relief for qualifying international employees, effectively reducing the tax rate on a significant portion of salary.

Box 3: Savings and Investment Allowances

While most deductions apply to Box 1, the tax-free threshold in Box 3 is equally important for overall tax planning.

Tax-Free Threshold (Heffingsvrij Vermogen)

For 2025, the Box 3 tax-free threshold is approximately €57,684 per person (approximately €115,368 for fiscal partners). Net assets below this threshold are not subject to Box 3 taxation.

How Box 3 Is Calculated

Following landmark court rulings (the "Kerstarrest" of December 2021), the Netherlands has been revising its Box 3 system. For 2025, the transitional system calculates deemed returns based on the actual composition of your assets:

  • Bank savings: A deemed return based on actual average savings interest rates.
  • Other investments: A higher fixed deemed return percentage.
  • Debts: A deduction based on a deemed interest rate.

The resulting deemed income is taxed at a flat rate of 36% for 2025.

Practical Example: If you have €150,000 in savings and no debts, your taxable Box 3 base would be €150,000 minus the €57,684 threshold = €92,316. The deemed return on savings might be approximately 1.03%, yielding deemed income of approximately €951, taxed at 36% = approximately €342 in tax.

Deductions and Allowances for Non-Residents

Non-residents earning income in the Netherlands face different rules regarding deductions and allowances.

Qualifying Non-Resident Taxpayer Status (Kwalificerend Buitenlands Belastingplichtige)

If you earn at least 90% of your worldwide income in the Netherlands, you may qualify as a "qualifying non-resident taxpayer" (KBB). This status grants you access to the same deductions and credits as Dutch residents, including:

  • Full general tax credit
  • Mortgage interest deduction (on a qualifying primary residence in an EU/EEA/Swiss home country)
  • Personal deductions (medical expenses, charitable donations, etc.)

You must provide documentation from your home country's tax authority proving your worldwide income to claim this status.

Non-Qualifying Non-Residents

If you do not meet the 90% threshold, your access to Dutch deductions is severely limited. You will receive:

  • A partial general tax credit (phased out since 2019 for non-qualifying non-residents)
  • The labour tax credit (if applicable)
  • No mortgage interest deduction or personal deductions

Double Taxation Treaties

The Netherlands has an extensive network of tax treaties with over 90 countries to prevent double taxation. These treaties determine which country has the right to tax specific types of income and typically provide relief through:

  • Exemption method: Income taxed in one country is exempt in the other (with progression reservation).
  • Credit method: Tax paid in one country is credited against tax owed in the other.

If you're earning income across borders, understanding the applicable tax treaty is crucial for optimizing your Netherlands tax relief.

Common Mistakes and Misconceptions

Avoid these frequent errors when claiming Netherlands tax deductions:

  1. Assuming all mortgage interest is fully deductible: Remember the rate cap (36.97% for 2025) and the requirement for annuity/linear repayment on post-2013 mortgages.
  2. Forgetting the eigenwoningforfait: Many homeowners overlook that they must add back the deemed rental value, reducing the net benefit of the mortgage interest deduction.
  3. Not documenting periodic charitable donations: Verbal agreements are insufficient. You need a written donation agreement for at least five years to claim unlimited deduction.
  4. Ignoring the 30% ruling step-down: New expats may budget based on the full 30% rate without accounting for the reduction to 20% and then 10% over the five-year period.
  5. Non-residents claiming full deductions without KBB status: If you don't earn 90% of your worldwide income in the Netherlands, you cannot claim most personal deductions.
  6. Missing the filing deadline: The standard Dutch income tax return deadline is May 1 following the tax year. Extensions can be requested, but late filing may result in penalties.
  7. Overlooking fiscal partner benefits: Married couples and registered partners can optimize deductions by allocating income and deductions between partners in the most tax-efficient way.

Frequently Asked Questions

What is the personal tax allowance in the Netherlands for 2025?

The Netherlands does not have a traditional tax-free personal allowance. Instead, it uses tax credits (heffingskortingen) that are subtracted from your calculated tax. The general tax credit for 2025 is up to approximately €3,362, effectively making a portion of your income tax-free.

Can I claim tax deductions if I work remotely from the Netherlands for a foreign employer?

Yes, if you are a Dutch tax resident, your worldwide income is taxable in the Netherlands regardless of where your employer is based. You can claim all standard Dutch deductions and credits. However, a tax treaty may allocate taxing rights differently, so professional advice is recommended.

Is the 30% ruling still available in 2025?

Yes, but with modifications. The 30% ruling now features a step-down structure (30%/20%/10%) for new applications from 2024 onward. Existing beneficiaries may be covered by transitional provisions.

How do I calculate my Dutch tax liability with deductions?

Are pension contributions tax-deductible in the Netherlands?

Employer pension contributions are typically made pre-tax and do not appear as a separate deduction. Personal annuity (lijfrente) contributions can be deducted if you have a pension shortfall, subject to annual limits.

Conclusion and Key Takeaways

The Netherlands offers a comprehensive set of tax deductions and allowances for the 2025/2026 tax year that can meaningfully reduce your tax burden:
