Not sure whether your crypto belongs in Box 1 or Box 3? You’re not alone. Many Dutch investors struggle to figure out how to report their crypto assets correctly. Misclassifying your crypto income can lead to serious compliance issues, higher tax bills, or even unwanted scrutiny from the Belastingdienst.
In the Netherlands, most crypto holdings are taxed under Box 3, but if you’re actively trading, mining, or receiving crypto as payment, your activity might fall under Box 1 instead. Understanding this distinction is essential for accurate tax reporting.
In this guide, we’ll break down the key differences, explain how to classify your crypto activity, and show you how to report it properly to stay on the right side of Dutch tax law.
Understanding the Dutch Box System
The Dutch tax system uses a “box” framework to categorise different types of income. Each box has its own tax rules, rates, and reporting requirements. Crypto investors must understand these categories to correctly determine whether their holdings or earnings fall under Box 1, Box 2, or Box 3.
Box 1: Income from Work and Home Ownership
This box covers taxable income earned from employment, self-employment, freelance work, pensions, and home ownership. If your crypto activity involves professional trading, receiving crypto as salary, or running a mining business, it could be classified under Box 1. Income in this category is taxed progressively, with rates increasing as your income rises.
Box 2: Substantial Interest Income
Box 2 applies to individuals who hold a substantial interest, usually 5% or more, in a company. It covers dividends and capital gains from such shareholdings. This box is not generally relevant for most crypto investors unless they are also shareholders in a crypto-related business.
Box 3: Income from Savings and Investments
Box 3 is the most relevant category for typical crypto holders. It includes income from savings accounts, shares, property, mutual funds, and cryptocurrencies. Instead of taxing actual gains, the Dutch tax authority applies a fixed presumed return on your total asset value as of 1 January each year. This fictitious income is then taxed at a flat rate, regardless of whether you made a profit or not.

When Does Crypto Falls Under Box 3 in the Netherlands?
In most cases, the Dutch tax authority classifies cryptocurrency as a personal asset, making it subject to taxation under Box 3. This category focuses on the presumed returns from your overall wealth rather than actual income or capital gains.
Crypto as Part of Your Net Wealth
Cryptocurrencies are treated like savings or investments. That means if you’re simply holding, passively trading, or occasionally staking crypto without professional intent, it is included in your total wealth for Box 3 purposes. The Belastingdienst evaluates the net value of your assets on 1 January of each year, including crypto, and assumes you’ll earn a fictitious return on those assets.
Fictitious Returns Instead of Real Profits
Box 3 does not rely on real gains or losses. Instead, the Dutch tax office uses a fictitious return model based on your asset type and value on 1 January. Even if your portfolio decreases during the year, you may still owe tax based on the presumed return. This eliminates the need to track daily trading results but also removes the ability to deduct losses.
Flat Tax Rate on Presumed Income
The fictitious return is taxed at a flat rate of 36% (as of 2024). The return rate is calculated depending on the asset type, crypto, for example, is grouped with other investments and presumed to have a higher return than cash. Your debts may reduce the taxable amount if they exceed the minimum threshold.
Examples of Box 3 Crypto Activity
The following are typically reported under Box 3:
- HODLing coins or tokens without active trading
- Staking for passive yield (non-professional setup)
- Lending crypto on DeFi platforms as a personal investment
- Occasional buying or selling with long holding periods
- Receiving airdrops or forks passively
- Mining as a hobby.
In all these cases, your crypto is considered part of your worldwide assets and taxed as such.
When Does Crypto Falls Under Box 1 in the Netherlands?
While most casual crypto investors fall under Box 3, there are situations where your crypto activity may be reclassified under Box 1. This category is used when crypto becomes a source of income through active effort, skill, or consistent commercial activity.
Crypto as a Professional Income Source
Box 1 applies if your crypto activity resembles a business or job. If you are actively generating income through trading, mining, or receiving crypto as payment, the Dutch Tax Office may treat it as earned income. In such cases, you are taxed under the progressive income tax rates applicable to employment or self-employment.
Criteria for Box 1 Classification
The Belastingdienst looks for indicators that your crypto-related earnings go beyond passive investing. You may fall under Box 1 if:
- You engage in day trading or high-frequency crypto trading
- You earn crypto as salary from an employer or freelance work
- You operate a mining setup beyond a hobby level
- You use inside knowledge or specialised tools to profit
- You spend significant time and effort to maximise gains
The distinction often hinges on whether your actions exceed what’s considered “normal asset management.”
Tax Treatment Under Box 1
Income in Box 1 is taxed progressively based on total annual earnings:
- Up to €73,031: taxed at 36.93%.
- Above €73,031: taxed at 49.50%.
Additionally, if you’re considered self-employed, you may be eligible for business deductions, which can reduce your tax liability.
Examples of Box 1 Crypto Activity
The following crypto actions are usually taxed under Box 1:
- Running a mining business with regular income and expenses
- Receiving salary in crypto from an employer or client
- Daily trading or using bots to make consistent profits
- Providing paid services and accepting crypto as compensation
- Operating a validator node professionally, not passively
In these cases, crypto income is treated like any other form of labour income and must be reported accordingly.

Common Scenarios and Box Classification
To help you better understand how your crypto activity might be classified by the Belastingdienst, here are several common real-life situations and their likely tax box treatment. These examples demonstrate how different types of crypto behaviour influence whether you report under Box 1 or Box 3.
Scenario 1: Passive HODLing
You buy Bitcoin and hold it in a wallet without trading or earning rewards. Since you’re not actively managing the asset, it’s treated as part of your net wealth and taxed based on its value on 1 January.
Scenario 2: Receiving Crypto as Payment
You freelance as a graphic designer and accept crypto for your services. Crypto received as compensation for work is treated as income and must be reported under employment or self-employment earnings.
Scenario 3: Running a Mining Rig at Home
You mine Ethereum on your home setup, earning regular rewards. If it’s a hobby with minimal profits, it likely falls under Box 3. If you consistently generate income and reinvest in equipment, it qualifies as a business under Box 1.
Scenario 4: Active Day Trading
You buy and sell crypto multiple times a day for profit. Day trading involves effort, planning, and intent to profit, which goes beyond passive investing. This qualifies as income-generating activity.
Scenario 5: Staking Small Amounts of Tokens
You stake a few altcoins to earn passive rewards once a month. This is considered a passive investment. The rewards and value of the tokens are taxed as part of your overall wealth.
Scenario 6: Lending on DeFi Platforms
You lend USDC on a DeFi platform and receive interest over time. As long as the lending is not part of a structured business, it remains a passive activity taxed under Box 3.

Frequently Asked Questions
Can I Switch Between Box 1 and Box 3 Every Year?
No, switching between Box 1 and Box 3 arbitrarily each year is not allowed. The classification depends on the nature and consistency of your crypto activity, not personal preference. If your activity meets the criteria for Box 1, it must be declared as such, even if it was previously reported under Box 3.
Is There a Specific Threshold That Triggers Box 1 Taxation?
There is no fixed threshold in euros that triggers Box 1 classification. The Dutch tax authority looks at the intensity, frequency, and intent of your crypto activity. High volumes, frequent trading, or running a business-like operation are strong indicators that your crypto income falls under Box 1.
Do I Need to Register as a Business for Box 1 Crypto Activity?
Not necessarily. You don’t have to register as a business to fall under Box 1. However, if your crypto activities resemble self-employment or generate consistent income, they may be treated as such by the tax office. Registering can help you claim deductions, but it is not a requirement for Box 1 taxation.
Does Receiving Airdrops Automatically Trigger Box 1 Taxation?
Receiving airdrops does not automatically place your crypto under Box 1. In most cases, airdrops are considered passive and fall under Box 3. However, if the airdrops result from professional engagement, such as developer work or marketing services, they may be classified under Box 1 and taxed as income.
Can the Belastingdienst Reclassify My Crypto After Filing?
Yes, the Belastingdienst can audit your tax return and reclassify your crypto activity if they believe it was incorrectly reported. If they determine that your transactions exceed normal asset management, they can move your filing from Box 3 to Box 1. In such cases, penalties or additional tax may apply.
