Investing and Taxes in the Netherlands — Box 3 Explained
This is not tax advice. This article provides general information about the Dutch tax system for investors. Always consult a qualified tax advisor (belastingadviseur) for your personal situation. Tax rules can change — verify current information at Belastingdienst.nl.
Investing taxes in the Netherlands work very differently from most other countries. There is no capital gains tax — you do not pay tax when you sell investments at a profit. Instead, the Dutch tax authority (Belastingdienst) levies an annual wealth tax called Box 3, which is based on a deemed return (fictief rendement) on your total assets above a tax-free threshold.
For most beginning investors, the practical implication is simple: if your total assets (savings, investments, other wealth) remain below €59,357 per person, you owe zero Box 3 tax. Once you cross that threshold, you pay 36% tax on a notional return — not on your actual gains.
This guide explains exactly how Box 3 works, how to report your investments at tax time, and what mistakes beginners commonly make. For an overview of the best brokers available in the Netherlands, see our broker comparison.

How Does Box 3 Tax Work for Investors?
Box 3 — formally the vermogensrendementsheffing (wealth return tax) — is the Dutch system for taxing savings and investments. It operates in three steps:
- Determine your assets on 1 January: The reference date is always 1 January of the tax year. The Belastingdienst looks at the total value of your assets minus qualifying debts on that date.
- Deduct the tax-free threshold: In 2026, the tax-free threshold (heffingsvrij vermogen) is €59,357 per person. Fiscal partners share a combined threshold of €118,714. Everything below this threshold is tax-free.
- Apply the deemed return and tax rate: On the portion above the threshold, the Belastingdienst applies a fixed deemed return percentage. You then pay 36% tax on that deemed return.
The key difference from capital gains tax systems: it does not matter whether you made a profit. You pay based on a notional return, regardless of whether your investments rose or fell. This can work against you in a bad market year — but can also work in your favour if your actual return exceeds the deemed percentage.
Deemed Return Percentages for 2026
| Asset Category | Deemed Return 2025 | Deemed Return 2026 |
|---|---|---|
| Bank and savings accounts | 1.37% | 1.28% (preliminary) |
| Investments and other assets | 5.88% | 6.00% (final) |
| Debts | 2.70% | 2.70% (preliminary) |

If your assets above the threshold consist entirely of investments (no savings), the full 6.00% deemed return applies in 2026. If you hold a mix of savings and investments, the Belastingdienst calculates a weighted average based on the actual composition of your assets.
Actual return option (tegenbewijsregeling): From the 2025 tax year onwards, you can report your actual investment return in your tax return. If your actual return is lower than the deemed return, the Belastingdienst will use the lower figure for your assessment.
Worked Example: €30,000 in Investments
Suppose you are single, hold €30,000 in investments on 1 January 2026, and have no other assets or debts.
- Total assets: €30,000
- Tax-free threshold 2026: €59,357
- Taxable base: €0 — your assets fall entirely below the threshold
- Box 3 tax owed: €0
Most beginning investors will pay zero Box 3 tax — the threshold is generous enough that a portfolio of €30,000 or less generates no tax liability when it is your only asset.
Now suppose you hold €30,000 in investments and €60,000 in savings (total: €90,000):
- Total assets: €90,000
- Threshold: −€59,357
- Taxable base: €30,643
- Deemed return on investment portion (6.00%): ~€1,800
- Tax at 36%: ~€648
Note: This is a simplified illustration. The actual calculation is more complex because the Belastingdienst applies a weighted deemed return across the full asset base including the exempt amount. Use the Belastingdienst calculation tool or consult a tax advisor for your precise situation.

How to Report Investments at Tax Time
Every broker that holds Dutch resident accounts is required — or strongly encouraged — to provide an annual overview of your portfolio value on 1 January. You use this to complete Box 3 in your Dutch income tax return (belastingaangifte).
eToro Tax Reporting
eToro is a foreign broker regulated by CySEC in Cyprus. Your eToro account qualifies as a foreign investment account (buitenlandse beleggingsrekening) and must be reported in Box 3 of your Dutch tax return — even if its value falls below the tax-free threshold. eToro does not automatically report to the Dutch tax authority; you must retrieve the information yourself.
To download your eToro annual statement: log in → Portfolio → History → Account Statement → set the full calendar year period → download PDF or Excel. Note the portfolio value on 1 January of the relevant tax year.
For a full overview of the platform, read our eToro Netherlands review.
DEGIRO Tax Reporting
DEGIRO is a Dutch-origin broker regulated by the AFM. DEGIRO provides an annual account overview (jaaroverzicht) in your account, including the portfolio value on 1 January and a summary of dividends received and withholding taxes deducted — both useful for your tax return.
To find your DEGIRO annual statement: log in → Activity → Annual Report → select the relevant year → download PDF.
Dividend Withholding Tax on VWRL
If you hold the Vanguard FTSE All-World UCITS ETF (VWRL, ISIN: IE00B3RBWM25), you receive quarterly dividends. Because VWRL is Irish-domiciled, the fund already deducts 15% US withholding tax on American dividends before they reach you (dividend leakage). Additionally, the Netherlands may withhold 15% Dutch dividend tax on the distribution itself, which you can partially offset against your Box 3 liability.
Accumulating ETFs like VWCE (ISIN: IE00BK5BQT80) reinvest dividends automatically and do not distribute, simplifying your tax reporting. For a detailed comparison, see our guide on how to buy VWRL ETF.
Common Tax Mistakes Made by Beginner Investors
- Not reporting investments at all: All investments must be declared in Box 3, even if you made no profit and sold nothing. Box 3 taxes ownership on 1 January, not realised gains.
- Forgetting foreign broker accounts: eToro is a foreign broker. Your account must be declared as a foreign investment account in your tax return — even if the value is below the threshold. The Belastingdienst receives data on foreign accounts through international exchange programmes (CRS/FATCA). Failing to declare is risky.
- Omitting cryptocurrency: Bitcoin, Ethereum, and other crypto assets fall under Box 3 as “other assets”. Report their value on 1 January.
- Assuming tax is only due when you sell: Wrong. Box 3 tax is charged annually based on your assets on 1 January, regardless of whether you sold anything or realised any profit.
- Not deducting qualifying debts: Debts above a threshold of €3,800 per person can be deducted from your Box 3 assets, reducing your taxable base. Do not overlook this.
- Using the wrong date: The reference date is 1 January, not 31 December. Make sure you use the portfolio value on the correct date.

What is Changing? The Box 3 Reform (Expected 2028)
The current Box 3 system based on deemed returns has been legally contested since the Dutch Supreme Court’s landmark ruling in December 2021 (the “Kerstarrest”), which found the system incompatible with European human rights law.
The Wet werkelijk rendement box 3 (Real Return Act) was passed by the Dutch House of Representatives (Tweede Kamer) on 12 February 2026. If the Senate (Eerste Kamer) also approves it, the new system takes effect on 1 January 2028.
Under the new system:
- Tax is levied on your actual investment return — capital gains, dividends, and interest — not on a notional percentage
- A loss in one year can be carried forward to offset gains in future years (with a loss threshold of €500)
- A tax-free income allowance of approximately €1,800 per person replaces the current asset-based exemption
- The tax rate remains at 36%
Until 2028, the current system with deemed returns and the actual return option (tegenbewijsregeling) remains in force. Monitor updates on the Belastingdienst website and consult a tax advisor to understand how the reform will affect your specific situation.

Frequently Asked Questions: Investing Taxes Netherlands
Do I pay tax on my investments in the Netherlands?
Yes, if your total assets (savings + investments + other wealth) exceed the tax-free threshold of €59,357 per person (2026), you pay Box 3 tax. You are taxed on a deemed return of 6.00% on your investments — not on your actual gains. The tax rate on that deemed return is 36%. If your total assets fall below the threshold, you owe nothing.
Is there capital gains tax in the Netherlands?
No. The Netherlands does not have a capital gains tax for private individuals on Box 3 investments. You do not pay tax when you sell shares or ETFs at a profit. Instead, you pay Box 3 tax annually based on your total asset value on 1 January, regardless of whether you sold anything.
Do I need to declare my eToro account in the Netherlands?
Yes, always. eToro is a foreign broker (CySEC-regulated, based in Cyprus). Your eToro account must be declared as a foreign investment account in Box 3 of your Dutch tax return, even if its value is below the tax-free threshold. The Dutch tax authority exchanges financial data with foreign jurisdictions through CRS/FATCA programmes — failing to declare is a legal risk.
When is Box 3 tax due — when I sell or every year?
Every year, regardless of whether you sell. The reference date is 1 January. If you hold investments on that date, they count towards your Box 3 assets for that tax year — even if you did not sell a single share. There is no event-triggered tax on disposal of investments in Box 3.
Is Box 3 changing soon?
Yes. The Wet werkelijk rendement box 3 was adopted by the Dutch House of Representatives on 12 February 2026. If approved by the Senate, the new system takes effect on 1 January 2028. Under the reform, you will pay tax on your actual investment return instead of a deemed return. Until 2028, the current system with deemed returns remains in force.
