Crypto Tax in the Netherlands 2026: How Box 3 Works for Bitcoin

If you live in the Netherlands and own Bitcoin, the question of crypto tax in the Netherlands in 2026 works very differently from most of Europe. There is no tax on the moment you sell. Instead, the Belastingdienst (the Dutch Tax Administration) taxes the value of your crypto on 1 January through Box 3, using an assumed return. This beginner guide explains the 2026 numbers, shows a worked example, and covers the "actual return" option and the reform that is still being debated.

How crypto tax in the Netherlands works: Box 3 in a nutshell

Dutch income tax is split into three "boxes". Box 1 is work and home, Box 2 is substantial shareholdings, and Box 3 is savings and investments. According to the Belastingdienst, crypto assets such as bitcoin belong in Box 3, in the category "investments and other assets" (beleggingen en andere bezittingen).

That has three practical consequences for beginners:

No tax on each trade. Selling BTC for euros or swapping one coin for another is not itself a taxable event for a normal private investor.
The date that matters is 1 January. You add up the value of all your Box 3 assets (bank balances, shares, crypto) at 00:00 on 1 January and subtract your Box 3 debts.
Tax is charged on an assumed (fictional) return, not on what you actually made, unless you choose to report your actual return (more on that below).

If you are used to the German approach, where a one-year holding period can make gains tax-free, this is a completely different logic. Our guide to Bitcoin taxes in Germany shows the contrast.

The 2026 Box 3 numbers for crypto

These are the official figures for tax year 2026 published by the Belastingdienst. The savings and debt percentages are provisional and are finalised after the year ends.

Item	2026	2025
Tax-free allowance (heffingsvrij vermogen), per person	€59,357	€57,684
Tax-free allowance with a fiscal partner	€118,714	€115,368
Assumed return on investments and other assets (incl. crypto)	6.00%	5.88%
Assumed return on bank savings	1.28% (provisional)	1.37%
Box 3 tax rate	36%	36%

Good to know: the Belastingdienst also lists a separate threshold (€38,479 per person in 2026, €76,958 with a partner) above which you must report your wealth in your return because it can affect income-related schemes such as allowances (toeslagen). Reporting your assets does not automatically mean you owe tax.

Worked example: €100,000 of Bitcoin on 1 January 2026

Take a single person whose only Box 3 asset is €100,000 of bitcoin on 1 January 2026, with no savings and no debts. The calculation, in simplified form, looks like this:

Assumed return: 6% of €100,000 = €6,000.
Taxable base: €100,000 minus the €59,357 allowance = €40,643.
Taxable benefit: the assumed return is applied proportionally to that base, about €2,439.
Tax: 36% of €2,439 = roughly €878 for the year.

Notice what is missing: it does not matter whether your bitcoin rose 50% or fell 50% during 2026. The tax follows the 1 January value. The Belastingdienst applies the allowance automatically when you file.

How to declare crypto in the Dutch tax return

In the online return (aangifte inkomstenbelasting), crypto goes on the screen "Bankrekeningen en andere bezittingen". For recent years there is a separate tick box called "Cryptobezittingen", after which you enter the amount. (For returns covering 2024 or earlier, you ticked "Overige bezittingen" and entered the value under "Andere bezittingen".)

A short checklist:

Use the price at 00:00 on 1 January on the platform you actually use.
Add up everything: every exchange account plus coins in your own wallet. Moving coins to a hardware wallet does not take them out of Box 3. If you plan to do that, see how to move Bitcoin from an exchange to a hardware wallet.
Keep screenshots or exchange statements of your 1 January balances, plus a record of purchases and sales during the year in case you want to use the actual-return option.
Children's crypto: for a minor, the Belastingdienst adds the crypto to the parents' or guardians' Box 3 assets.

The "actual return" option (tegenbewijsregeling)

After the Dutch Supreme Court ruled in 2021 that the old fictional-return system breached the European Convention on Human Rights, the Belastingdienst now lets you report your actual return (werkelijk rendement) instead. Since tax year 2025, the return asks automatically whether you want to do this. If you choose it, the Belastingdienst uses whichever amount is more favourable: the fictional or the actual return.

For crypto you provide the value on 1 January and on 31 December, plus the total value of purchases and sales during the year. Two points beginners often miss:

"Actual return" means the real increase in value, including gains you have not cashed out. A year where BTC drops can make this option attractive; a strong year usually will not.
According to the Belastingdienst, the tax-free allowance does not apply when your actual return is calculated, following a Supreme Court ruling.

When crypto can fall into Box 1 instead

Box 3 is the starting point, not a guarantee. The Belastingdienst says ordinary crypto trading is comparable to speculating on currencies, so you do not declare trading profits separately. That changes if you regularly earn extra income through additional work on top of normal investing, or if mining income exceeds your costs. Then it can count as income from other work (resultaat uit overige werkzaamheden) or business profit, which is taxed in Box 1 at progressive rates. Being paid a salary in crypto is also Box 1 income. If you run validators, trading bots or mining rigs at scale, get advice for your specific case.

What changes next: the Box 3 reform

The Netherlands wants to move to taxing actual returns. The bill "Wet werkelijk rendement box 3" passed the House of Representatives on 12 February 2026 but is still waiting in the Senate. On 3 November 2026 the cabinet told parliament the new system can probably only start in 2029 rather than 2028, and that the full move to a capital gains tax, including crypto, remains planned for 2030. Until then, cabinet plans would tax assets such as savings and crypto on yearly value growth. These plans can still change, so check the latest position before relying on them.

Separately, EU-wide reporting under DAC8 means crypto providers collect user data from 2026, which makes it easier for the Belastingdienst to cross-check what you declare. Our DAC8 explainer covers what is shared.

FAQ: Dutch crypto tax for beginners

Do I pay tax in the Netherlands when I sell Bitcoin?
For a normal private investor, no. Selling or swapping is not taxed itself; your crypto is taxed through Box 3 based on its value on 1 January.

Is there a tax-free amount for crypto in the Netherlands?
Yes, but it covers all your Box 3 wealth together, not crypto alone: €59,357 per person in 2026, or €118,714 with a fiscal partner.

What if my crypto lost value during the year?
You can report your actual return. If it is lower than the 6% fictional return, the Belastingdienst uses the lower amount.

Bottom line

In the Netherlands, crypto is wealth, not a trading event. What counts is your total Box 3 wealth on 1 January: above €59,357 per person, an assumed 6% return on crypto is taxed at 36% in 2026. Keep your 1 January balances and yearly trade records, compare the actual-return option in a bad year, and follow the reform news, because the system is expected to change from 2029 or 2030.
