The Dutch Tax System
The Netherlands taxes wealth differently from income. Understand the box system, the deemed returns and the mortgage interest deduction to know what your investments yield after tax.
8.1 Box System
The Netherlands operates a box system in which different types of income and wealth are each taxed in their own "box".
| Box | Tax type | What falls under this |
|---|---|---|
| Box 1 | Progressive: 36.97%–49.50% | Income from employment and owner-occupied home (incl. imputed rental value) |
| Box 2 | 24.5% (up to €67,000) / 33% (above that) | Substantial interest (≥5% shares in a private limited company) |
| Box 3 | Wealth return levy | Savings, investments, real estate (rental), crypto |
8.2 Savings & Term Deposits → Box 3
Both fall under Box 3: the wealth return levy. The Dutch Tax Authority uses a deemed return per asset category (not your actual return).
- Tax-free allowance: €57,684 per person (2024), below this you pay nothing
- Deemed return on savings: approximately 1.03% (2024)
- Deemed return on other investments: approximately 6.04% (2024)
- On the deemed return you pay 36% tax
The system is under pressure following the Christmas Ruling (2021) by the Supreme Court, which ruled that the deemed return violates property rights. A transition to taxation on actual returns is underway, expected from 2028.
8.3 Stocks → Box 3
Stocks in listed companies fall under Box 3. Capital gains and dividends are not taxed separately — only the deemed return of ~6.04% counts.
You do need to offset dividend tax (15%) that has already been withheld at source. This is creditable against your tax return.
Exception: Box 2
If you own 5% or more of shares in a private limited company (substantial interest), you fall under Box 2: 24.5% on the first €67,000 of profit, 33% above that.
8.4 Bonds → Box 3
Bonds fall under Box 3, category "other investments". Deemed return: ~6.04%, taxed at 36%. Actual interest income is therefore not directly taxed.
8.5 Investment Funds & ETFs → Box 3
Fall under Box 3, category "other investments". Same deemed return of ~6.04%. Dividends from funds: 15% dividend tax is withheld, creditable against your return. Funds qualifying as a fiscal investment institution (FBI) have special rules.
8.6 Crypto → Box 3
Cryptocurrencies fall under Box 3 as "other assets". Deemed return: ~6.04%, taxed at 36%. You declare the value on reference date 1 January in your tax return.
Many people forget to declare crypto — this is however mandatory. There is no specific crypto legislation in the Netherlands; it falls under the existing wealth tax.
8.7 Real Estate → Depends on use
Real estate has the most complex tax treatment.
| Situation | Box | Treatment |
|---|---|---|
| Owner-occupied home (primary residence) | Box 1 | Imputed rental value (0.35% of WOZ value) as deemed income; mortgage interest deductible |
| Rental property / 2nd home | Box 3 | WOZ value as basis; deemed return ~6.04% |
| Real estate via private company (BV) | Box 2 | Rental profit taxed under corporate income tax (CIT); dividend to private via Box 2 |
Mortgage Interest Deduction
The mortgage interest deduction is a tax scheme under which you may deduct the interest you pay on your mortgage from your taxable income in Box 1. This reduces your tax bill.
Voorbeeld
- Gross income: €60,000
- Annual mortgage interest: €8,000
- Taxable income after deduction: €52,000
- Tax benefit (at 36.97%): ±€2,958 per year (±€247 per month)
Conditions:
- The property must be your primary residence (not a holiday home or rental property)
- The mortgage must have an annuity or linear repayment structure (for loans taken out after 1 January 2013)
- Mortgages from before 2013 fall under transitional law and have more lenient conditions
- The deduction applies for a maximum term of 30 years
Maximum deduction rate
The deduction has been gradually phased down for years. You deduct the interest at a maximum of the rate of the second tax bracket, regardless of your actual tax rate. If you earn more than €75,518 (2024) and fall in the 49.50% bracket, you still only deduct the interest at 36.97%. You therefore miss the difference (~12.5%) as a benefit.
Imputed Rental Value (Eigenwoningforfait)
The counterpart to the mortgage interest deduction is the eigenwoningforfait: a deemed income that the government adds to your taxable income when you own a home.
- 0.35% of the WOZ value (for properties up to €1,310,000 in 2024)
- 2.35% over the part above €1,310,000
This deemed income reduces your net benefit from the mortgage interest deduction.
Voorbeeld
WOZ value: €400,000 → Imputed rental value: €400,000 × 0.35% = €1,400 extra taxable income
Deductible costs besides mortgage interest
Deductible:
- Arrangement fee / brokerage costs of mortgage adviser
- Notary costs for the mortgage deed
- Valuation costs (when taking out mortgage)
- National Mortgage Guarantee (NHG) costs
Not deductible: transfer tax, estate agent fees, renovation costs.

Key concepts
- Tax-free allowance (€57,684 p.p. in 2024): below this amount you pay no Box 3 tax. Fiscal partners together have a €115,368 exemption.
- Reference date: Box 3 wealth is measured on 1 January of the tax year.
- Actual return: The government is working on a new system in which you are taxed on your actual return instead of a deemed percentage. Implementation is expected around 2028.
