TL;DR: Dutch 36% Box 3 Tax on Unrealized Crypto Gains, Explained for Founders
Crypto news, November, 2026: the Dutch Box 3 reform could tax your unrealized crypto gains at 36% every year from 1 January 2028. You would pay even if you never sell a single satoshi. This summary shows what you might owe, so you can plan calmly now instead of selling Bitcoin at a bad price in May 2029.
- How the tax works: The tax office compares the value of your Box 3 assets on 1 January each year. Any rise counts as income. After a tax-free return of €1,800 per person (€3,600 for couples), 36% applies to the gain, not to your whole stack.
- What it could cost you: Picture a €100,000 Bitcoin treasury that rises 60%. The tax would be about €20,952, and you would have no extra cash to pay it. If prices crash later, you get a loss carry-forward for losses above €500. You get no refund for tax already paid.
- What changed after the House vote on 12 February 2026: The government now wants shares, bonds, options and crypto ETPs taxed on sale from 2028. Crypto in your own wallet, gold and foreign currency would stay on the yearly levy until at least 2030. The Senate still has to decide, so the rules are not final.
- How to prepare: List your holdings by wrapper: wallet, exchange, ETP or BV. Set aside 36% of your year-to-date gains in euros. Save your 1 January balances, and log every loss above €500. Test a bull year, a flat year and a crash year in a simple spreadsheet.
Violetta Bonenkamp (Mean CEO), founder of CADChain and Fe/male Switch, argues that this design punishes holding. It also pushes you away from self-custody and toward financial intermediaries. EU DAC8 reporting went live in 2026, so exchanges now report your data to the Belastingdienst. Hiding is no longer an option.

Crypto news in November, 2026 keeps returning to the question Dutch founders ask me at almost every meetup: “How much of my Bitcoin will the tax office take before I sell a single satoshi?” The answer sits inside a reform with a long Dutch name, the Wet werkelijk rendement box 3 (the Actual Return in Box 3 Act). The Dutch House of Representatives passed it on 12 February 2026. In its House-passed form, it puts a flat 36% tax on actual investment returns, including UNREALIZED gains, from 1 January 2028.
I am Violetta Bonenkamp, better known as Mean CEO. I run CADChain, a Dutch deeptech company that uses blockchain to protect intellectual property in CAD files, and Fe/male Switch, a game-based startup incubator. I have worked inside the Dutch blockchain scene for years. I was nominated for Impact Person of the Year at Dutch Blockchain Week 2022, and CADChain was one of 12 startups worldwide selected for the OECD Global Blockchain Policy Forum. So I read this law as a founder, a taxpayer and someone who designs incentive systems for a living. My verdict: the Dutch government has built an incentive machine that PUNISHES HOLDING, and most entrepreneurs have not run the numbers yet.
This article explains how Box 3 works, what the 36% rule means in euros, what has shifted since the House vote, and how founders, freelancers and business owners can prepare. Let’s break it down.
What is Box 3 in the Netherlands, and why is it being rebuilt?
Dutch personal income tax is split into three “boxes”, and each box has its own rules. Founders need to know which box their assets fall into, because that one detail can change a tax bill by thousands of euros.
- Box 1: income from work and your owner-occupied home (salary, freelance profit, pension).
- Box 2: income from a “substantial interest”, usually a shareholding of 5% or more in a company such as your own BV (Dutch private limited company).
- Box 3: income from savings and investments. This is where privately held Bitcoin, Ethereum, stocks, bonds and other crypto assets sit.
For years, Box 3 used a “fictitious return” model. The state assumed your assets grew by a set percentage and taxed that assumption, whatever happened to your actual portfolio. The IMI Daily coverage of the Dutch Supreme Court ruling and Box 3 reform explains that in December 2021 the Dutch Supreme Court (Hoge Raad) found this system breached the right to property and the ban on discrimination under the European Convention on Human Rights. Savers were paying tax on returns they never earned, during years of near-zero interest rates.
The interim system still runs today. The DropsTab analysis of EU crypto reporting and the Dutch Bitcoin tax vote notes that the Dutch tax authority’s 2026 guidance uses a 36% rate and an assumed 6.00% return on “investments and other assets”. On €100,000 of Bitcoin, that means €6,000 of assumed return and a tax bill of about €2,160 a year, roughly 2.16% of the position, before thresholds. Annoying, yes. Predictable, also yes. The 2028 model removes that predictability.
How does the 36% tax on unrealized crypto gains work?
Here is the mechanism in plain language. The tax authority (the Belastingdienst) compares the value of your Box 3 assets on 1 January of one year with their value on 1 January of the next. If the value went up, the increase counts as taxable income. You do not need to sell anything. Dividends, interest and rent also count as return. After a small tax-free amount, the rest is taxed at 36%.
Some quick definitions so nothing gets lost:
- Unrealized gain (paper gain): an increase in market value of an asset you still hold.
- Realized gain: profit you lock in by selling.
- Mark-to-market taxation: taxing assets as if you sold them at market price on a reference date, every year.
- Tax-free return: about €1,800 per person per year, or €3,600 for married couples, according to the reporting cited below.
- Loss carry-forward: net losses above €500 can be carried forward indefinitely to offset future gains. Losses below €500 are lost.
A detail many people miss is that the 36% applies to the RETURN, never to the full value of your holdings. As the Yahoo Finance report on the Box 3 plan for crypto and physical gold puts it, investors would not lose 36% of their Bitcoin every year. The rate hits the yearly increase. In a strong year, though, that increase can be large.
Worked examples: what would Dutch crypto holders owe?
I ran these numbers the way I would test a startup business model: different scenarios, simple math and no wishful thinking. Figures use the thresholds above and the House-passed rules.
- The freelancer with a small stack: your Bitcoin rises by €10,000 in a year. Taxable: €10,000 minus €1,800 = €8,200. Tax: €2,952.
- The married couple: a €50,000 paper gain minus the €3,600 couple exemption leaves €46,400. At 36%, the bill is €16,704, due in May, as the CryptocurrencyHelp worked examples for Dutch Bitcoin holders show.
- The founder with a €100,000 treasury: Bitcoin rises 60%. The paper gain is €60,000. After the €1,800 threshold, the tax is €20,952, and you hold zero extra euros in your bank account.
- The bull-then-crash scenario: your portfolio is worth €50,000 on 1 January 2028 and €100,000 on 1 January 2029. You pay about €17,352 in tax on the €48,200 taxable gain. During 2029, Bitcoin halves and you are back at €50,000. You get a €50,000 loss to carry forward, and NO REFUND for the €17,352 you already paid.
Scenario four is the one that keeps me up at night. You can finish a four-year cycle with the same amount of Bitcoin you started with, at the same price, and still be poorer by tens of thousands of euros. The loss carry-forward only helps if a future gain shows up to absorb it.
Why are Dutch crypto holders criticizing the unrealized gains tax?
The anger in the Dutch crypto community comes down to one word: LIQUIDITY. A tax bill arrives in euros, and paper gains do not pay bills. The CryptoTicker breakdown of the Dutch 36% unrealized crypto tax names forced liquidation as the main criticism. Investors may need to sell part of their holdings simply to pay the tax on those holdings.
The Coin Bureau video explainer on the 36% unrealized gains law calls this the “liquidity death spiral”. You hold Bitcoin, the price rises, you owe tax, you sell Bitcoin to pay, and if thousands of people do this at once, the selling pushes prices down. Here are the main complaints I hear from founders and investors:
- Forced selling: holders must convert crypto to euros every spring, often at bad moments.
- Volatility mismatch: a December rally can create a big bill, even if prices crash in January.
- No refund for tax already paid during peak years, only a carry-forward.
- Unequal treatment: real estate and startup shares are exempt from mark-to-market taxation, while Bitcoin is fully exposed.
- Penalty on compounding: every year’s tax shrinks the base that would otherwise grow.
- Exit pressure: the Digital Watch Observatory report on Bitcoin and Ethereum gains under Dutch law notes critics expect some investors to move to friendlier jurisdictions.
Why did the government choose this design anyway?
The government’s reasoning is mostly about money and speed. The Our Crypto Talk analysis of the Dutch government’s revenue motives reports that delaying reform would cost the treasury an estimated €2.3 billion per year. Officials also admitted that a pure realized-gains system would take longer to build, so they picked annual taxation of paper gains because it was easier to run by 2028. The stated long-term goal remains a move toward taxing gains on sale.
I respect the legal pressure. The Supreme Court left lawmakers with a hole in the budget and a broken system. Choosing a design because it is easier for the tax office, while it is harder for citizens, still flips the logic of good product design on its head. I build software for engineers, and my rule at CADChain is that “protection and compliance should be invisible.” Box 3 in its House-passed form makes compliance painfully visible, every single year.
What has changed since the House of Representatives vote?
This is where the November, 2026 picture gets interesting. The House vote did not end the story. The bill went to the Dutch Senate (Eerste Kamer), and the government signalled it wants to adjust course. According to The Bitcoin Conference’s post on the Netherlands rethinking its unrealized gains tax, the revised direction looks like this:
- Shares, bonds and options would move to a tax-on-sale system from 2028.
- Crypto, gold and foreign currency would stay on an annual levy on paper gains until at least 2030.
- Crypto ETPs (exchange-traded products that track crypto prices and trade on regular exchanges) would get the tax-on-sale treatment.
- Whether directly held Bitcoin will ever get the same treatment has not been confirmed.
The same post sums it up perfectly: “Same asset. Same price. That’s the Dutch plan.” Hold Bitcoin in your own wallet and you pay every year. Hold a Bitcoin ETP and you pay when you sell. The post’s author adds a line every founder should remember: “the wrapper is starting to decide the tax.”
Yahoo Finance also reports that the government has been examining whether limited backward loss relief (offsetting a loss against an earlier year’s gain) could be introduced from 2029. The honest status, based on the reporting available to me: the framework is NOT FINAL, the Senate still matters, and details may move again. Anyone telling you they know the exact 2028 bill for your wallet is guessing.
Which statistics show what is at stake for the Netherlands?
- 36%: the flat Box 3 rate on actual returns, including paper gains, in the House-passed version.
- €1,800 / €3,600: the annual tax-free return for individuals and married couples.
- €500: losses below this amount are written off and cannot be carried forward.
- €2.3 billion: the estimated yearly revenue loss the government wanted to avoid by moving fast.
- $96 million to $1.42 billion: the jump in indirect crypto holdings by Dutch companies, organisations and households between 2020 and October 2025, a nearly 15x increase.
- €113 million: direct crypto holdings of the Dutch financial sector in Q3 2025, just 0.03% of total Dutch securities holdings.
- €18,000: the possible bill on a €50,000 paper gain at 36%, before allowances, on Bitcoin you never sold.
- 2.16%: the approximate yearly carry cost of a €100,000 Bitcoin position under the current 2026 assumed-return system.
Put the 0.03% next to the €2.3 billion and you see the political logic. Crypto is a small slice of Dutch wealth, so lawmakers treat it as a rounding error. For the people holding it, often young founders, developers paid in tokens and freelancers who saved through crypto, it is a large slice of their net worth.
What does Mean CEO think Box 3 really teaches entrepreneurs?
Here is why I care beyond my own wallet. I design game economies for Fe/male Switch, and in game design, a tax on holding has a name: a decay mechanic (economists call a similar idea demurrage). Designers add decay on purpose when they want players to spend, trade and churn instead of hoarding. Box 3 in its House-passed form installs a decay mechanic on long-term crypto holders. Every May, the system nudges thousands of Dutch residents to sell. Whether lawmakers intended it or not, that is the behaviour the rules reward.
My second insight is about the exemptions. Startup shares and real estate are excluded from mark-to-market taxation. That tells me the government fully understands that taxing illiquid paper value can crush builders. It protected the founder holding unlisted shares and left the founder holding Bitcoin exposed. For a lot of web3 teams, token or crypto holdings work like startup equity: illiquid in practice when you would need to sell into a falling market, and tied to years of work.
My third insight concerns the ETP split. If wallets pay yearly and ETPs pay on sale, the law pushes Dutch residents from self-custody toward financial intermediaries. I spent years arguing at policy tables, including the OECD forum, that regulation should reflect technical reality and the needs of small players. A rule where the custody method decides the tax rate is a rule that quietly rewards incumbents.
And my fourth insight: hiding is not a strategy anymore. EU crypto reporting under DAC8 (the EU directive requiring crypto service providers to report user data to tax authorities) went live in 2026. Exchanges report. Plan as if the Belastingdienst sees everything, because increasingly it does.
One more provocation. Coin Bureau suggests the Netherlands may be “the first domino” and that other finance ministers will be taking notes. I agree. If you run a business anywhere in Europe, treat this as a preview of a debate coming to your country.
How can founders and freelancers prepare for the Dutch crypto tax? A step-by-step guide
I run my companies with structured experiments, and I apply the same thinking here. None of this is tax advice. It is the playbook I would use myself and then check with a qualified Dutch tax adviser.
A quick example from a founder’s desk
Picture Anna, a solo SaaS founder in Utrecht. She holds €40,000 in Bitcoin privately and €20,000 in an ETP. In 2028, both rise 50%. Under the revised direction, her wallet’s €20,000 gain creates a taxable return of €18,200 and a bill of about €6,552. Her ETP gain of €10,000 creates no bill until she sells. Same asset, same year, two outcomes. Anna’s move: she builds a €6,500 euro buffer during the year from her SaaS revenue, so she never has to sell Bitcoin in May.
What are the most common mistakes Dutch crypto holders make about Box 3?
- Thinking the state takes 36% of your whole stack. The rate applies to the yearly return, after the tax-free amount.
- Treating the House version as the final law. The Senate and government revisions can still change the rules for crypto.
- Counting stablecoins as cash. They are crypto assets and count as investments.
- Forgetting the no-refund rule. Losses only carry forward. Tax paid in a peak year stays paid.
- Ignoring the €500 loss floor. Many small losses add up to nothing under the House-passed rules.
- Relying on an exchange dashboard as your only record. Keep independent 1 January snapshots.
- Panic-relocating. Moving countries involves residence tests, family, business contracts and tax in the new country. Run the numbers first.
- Mixing company and personal wallets. It creates confusion across Box 2, Box 3 and corporate tax.
- Assuming you can stay invisible. EU reporting rules make that a losing bet.
- Waiting until 2028 to plan. Structure decisions are cheaper and easier while the law is still being shaped.
Who wins and who loses under the new Box 3 rules?
Likely winners
- Holders of startup shares and real estate, which are exempt from mark-to-market taxation.
- Savers with small balances below the tax-free threshold.
- ETP issuers and brokers, if the ETP exception passes.
- The Dutch treasury, which protects an estimated €2.3 billion a year.
Likely losers
- Long-term Bitcoin holders who use self-custody.
- Founders and developers paid partly in tokens or crypto.
- Freelancers whose savings sit mostly in crypto and who lack euro buffers.
- The Dutch crypto ecosystem, if mobile founders and capital leave.
Frequently asked questions about the Dutch 36% crypto tax
When does the Dutch tax on unrealized crypto gains start?
The target date is 1 January 2028, pending Senate approval. The first bills would land in the following year.
Does the 36% tax apply to stocks and bonds too?
The House-passed version covers stocks and bonds as well. The government’s revised direction moves shares, bonds and options to a tax-on-sale system from 2028, while crypto, gold and foreign currency stay on the annual levy until at least 2030.
Are real estate and startup shares taxed on paper gains?
No. Both are exempt from mark-to-market taxation and are taxed when gains are realized.
What happens if Bitcoin falls after I paid the tax?
You can carry net losses above €500 forward without a time limit to offset future gains. You do not get a refund for tax already paid, although the government is examining limited backward loss relief from 2029.
Is a Bitcoin ETP taxed differently from Bitcoin in my wallet?
Under the revised plan, yes. ETPs would be taxed on sale, while directly held Bitcoin would be taxed yearly on paper gains. This could still change before the rules are final.
So what should entrepreneurs do now?
Next steps. The Dutch Box 3 reform started as a court-ordered repair job and turned into a live experiment in taxing wealth that exists only on a screen. For entrepreneurs, the lesson reaches beyond the Netherlands. Where and how you hold an asset now shapes your tax as much as what the asset is. Wallet or ETP, private or company, Dutch resident or not: each choice needs its own math.
My advice as Mean CEO is the same advice I give founders inside Fe/male Switch: treat this like a strategic game with real consequences. Collect information early, run cheap scenario tests, build a euro buffer and speak up while the Senate is still deciding. The founders who prepare in 2026 and 2027 will make calm decisions in May 2029. The ones who wait will sell their Bitcoin at whatever price the market offers that week.

People Also Ask:
What is crypto in simple terms?
Crypto, short for cryptocurrency, is digital money that exists only online, with no physical coins or bills. Cryptography secures each transaction, and a public ledger called a blockchain records it. A network of computers maintains that ledger instead of a central bank or government. Bitcoin and Ethereum are the best-known cryptocurrencies.
Can cryptocurrency replace traditional money?
Cryptocurrency is unlikely to fully replace traditional money anytime soon. Its price swings make it hard to use as a stable store of value or for everyday payments. Most governments also still rely on their own currencies for taxes, wages, and monetary policy. Crypto will more likely keep growing alongside government-issued money, especially for cross-border payments. Stablecoins and central bank digital currencies blend features of both systems.
Who is Binance?
Binance is the world's largest cryptocurrency exchange by trading volume. Changpeng Zhao founded it in 2017. The platform lets users buy, sell, and trade hundreds of digital assets, and it runs its own blockchain and BNB token. Binance has faced legal action from regulators in several countries. It recently reported a security breach estimated at $6.3 billion, paused withdrawals, and announced plans to resume them in phases.
What is crypto used for?
People use crypto to make online purchases, send money across borders quickly and cheaply, and invest or trade in hopes of price gains. Some cryptocurrencies, like Ethereum, power smart contracts and decentralized apps for lending, borrowing, and digital collectibles. Stablecoins track the value of currencies like the U.S. dollar and are popular for payments and for holding value between trades.
How to invest safely in crypto?
Invest only money you can afford to lose, since crypto prices can rise and fall sharply. To protect your money:
- Use well-known, regulated exchanges.
- Turn on two-factor authentication.
- Move long-term holdings into a hardware wallet you control.
- Spread your money across several assets instead of putting everything into one coin.
- Research projects before buying, and avoid anyone promising guaranteed returns.
How does cryptocurrency work?
Cryptocurrency runs on a blockchain, a shared digital ledger copied across thousands of computers worldwide. When someone sends crypto, the transaction is broadcast to the network. Participants verify it through processes like mining or staking, then add it to a block of records. Once confirmed, the entry is very hard to change, which keeps the system secure without a bank in the middle.
What is crypto mining?
Crypto mining uses computer power to verify transactions and add new blocks to a blockchain. Miners compete to solve difficult math puzzles, and the winner earns newly created coins plus transaction fees. Bitcoin relies on mining, which uses large amounts of electricity. Networks like Ethereum have switched to staking, a less energy-heavy method.
What is a crypto wallet?
A crypto wallet stores the private credentials needed to access and send your cryptocurrency. Hot wallets are apps or browser extensions connected to the internet, which makes them convenient for frequent trading. Cold wallets, like hardware devices, stay offline and give stronger protection against hacks. Anyone who gets your secret recovery phrase can take your funds, so never share it.
What determines the price of crypto?
Supply and demand on exchanges set crypto prices. Investor sentiment, news headlines, government regulation, acceptance by businesses, interest rates, and a coin's total supply all move prices. Bitcoin has a fixed cap of 21 million coins, which some investors see as a reason for long-term value. Crypto markets trade 24/7 and react quickly to events like hacks, so prices are often highly volatile.
Is crypto a good investment for beginners?
Crypto can suit beginners with a high tolerance for risk, but it should usually make up only a small part of a portfolio. Prices are highly volatile, assets can become hard to sell quickly, and exchange hacks or scams can cause losses. Beginners often start with established coins like Bitcoin or Ethereum and buy small amounts over time. Learning how wallets and exchanges work before investing more also helps.
FAQ on the Dutch 36% Box 3 Crypto Tax and Unrealized Gains
Do staking rewards, airdrops and DeFi yields count under the new Box 3 rules?
Very likely. The actual-return model taxes income such as interest and dividends alongside yearly value changes, so staking rewards, lending yield and stablecoin interest should count as return. Record each reward's euro value when you receive it, and ask an adviser how LP tokens and airdrops are valued. Read IMI Daily's breakdown of income taxed under the Box 3 Act.
Are developers paid in tokens taxed in Box 1 or Box 3?
Usually both. Tokens received as salary or freelance fees are generally Box 1 income at their euro value on the day you receive them. Once you hold them privately, later price changes fall into Box 3. Record the value on receipt and set aside euros for both tax bills. See how Dutch founders prepare crypto treasuries and records.
Can losses on stocks offset paper gains on my Bitcoin?
Under the House-passed version, Box 3 pools returns across all assets, so a loss on shares reduces a gain on crypto. If shares move to tax-on-sale while crypto stays on the annual levy, netting losses against gains may get more complicated. Track each asset class separately until the Senate settles the final structure. Read Yahoo Finance on Box 3 loss treatment for crypto and gold.
How can fiscal partners split Box 3 returns to lower their crypto tax?
Fiscal partners can currently divide joint Box 3 income in any ratio they choose, which helps them use both allowances in full. Check that the 2028 rules keep this flexibility, register your fiscal partnership correctly, and decide whose name holds each wallet before large gains build up. See CryptocurrencyHelp's married-couple tax calculation.
Does MiCA licensing affect how my crypto data reaches the Dutch tax office?
Yes, indirectly. Since July 2026, EU exchanges need full MiCA authorization, and licensed providers also report under DAC8. Expect the Belastingdienst to receive your balances and transactions on regulated platforms automatically. Make sure your own records match the exchange's data before you file. Read Web3 News on MiCA and EU compliance for founders.
Should a Dutch startup accept crypto payments at checkout?
Only if you have a clear reason. Crypto received by your BV falls under corporate income tax rather than Box 3, but it adds reconciliation, refund and volatility work. Converting to euros at settlement keeps your books clean. Test whether customers actually want to pay in crypto before adding the option. Use the Stripe crypto checkout decision test.
What treasury rules should a BV holding crypto adopt?
Write a short treasury policy covering these points:
- The maximum share of reserves held in crypto.
- Who is allowed to move funds.
- Multi-signature approval for transfers.
- Monthly reconciliations.
- An external review.
Keeping founder wallets separate from company wallets protects you on both tax and governance. Read the lessons from a former CFO's $35M crypto case.
How could Box 3 affect Dutch web3 fundraising and token compensation?
Investors already demand legal clarity, and an annual tax on tokens that employees hold privately makes token-heavy pay less attractive to Dutch hires. Consider offering euro salaries plus equity instead. Model new hires' Box 3 exposure when drafting offers, and explain your tax structure clearly in investor decks. See why a16z rewards legal clarity in crypto.
Is Bitcoin still a sensible treasury asset for Dutch founders?
It can be, but size the position for cash flow, not conviction. A 60% rise on €100,000 could mean roughly €21,600 in tax before allowances. Keep most of your operating runway in euros, cap your crypto exposure, and plan for a price drop arriving right when the tax bill is due. Read DropsTab on Bitcoin volatility as a cash-flow problem.
Should Dutch crypto founders relocate or incorporate elsewhere in Europe?
Compare the whole picture first. Emigrating can trigger a Dutch protective tax assessment on the Box 2 shares in your BV. The new country's crypto rules, social security and company substance requirements also matter. Get advice in both countries, and weigh the local startup ecosystem, funding and talent too.
