Cryptocurrency is treated as a taxable asset in the Netherlands. 

The Dutch Tax and Customs Administration, known as the Belastingdienst, classifies crypto under the country’s three-box income tax system, with holdings generally falling into Box 3: income from savings and investments. 

Uniquely, the Netherlands does not tax actual realised gains on crypto in the conventional sense. Instead, investors are taxed on a presumed (fictitious) return calculated against the total value of their assets on 1 January each year, above a tax-free threshold.

Key Overview

• Crypto is classified as an asset under Box 3 of the Dutch income tax system (Wet inkomstenbelasting 2001), with a presumed return of 5.88% (2025) taxed at 36%.
• Following the 2024 Supreme Court ruling, taxpayers whose actual return is lower than the notional return may submit actual figures to the Belastingdienst.
• Specific crypto income, including salaries paid in crypto, professional day trading, and business mining, falls under Box 1 and is taxed at progressive income tax rates of 35.75% to 49.5%.
• The current Box 3 system is under transitional rules and is scheduled to be replaced by a Capital Growth Tax and Capital Gains Tax regime from January 2028.

Capital Gains Tax Rules

The Netherlands does not currently operate a conventional capital gains tax on crypto in the sense understood by most other jurisdictions. 

Under the existing regime, a crypto investor is not taxed when they buy, sell, or exchange cryptocurrency. Instead, the taxable event is holding the asset, the value of your crypto portfolio as it stands on 1 January each year is the basis for calculating Box 3 tax. 

The Belastingdienst calculates a notional yield on that balance, and 36% tax is applied to the notional return on assets above the annual tax-free allowance.

How Box 3 tax is calculated

The cost basis under Box 3 is determined by the market value of crypto holdings at 00:00 on 1 January of the relevant tax year, even if values have subsequently fallen by the filing deadline of 1 May. Crypto falls within the “investments and other assets” category, which carries a notional return rate of 5.88% for 2025. 

The 2024 Supreme Court ruling introduced an important exception: where a taxpayer can demonstrate that their actual return is lower than the notional figure, they may submit their real return and tax will be levied only on that lower amount. 

The burden of proof rests with the taxpayer.

Losses

If actual losses are incurred with no return at all, Box 3 income from assets for that year is set to zero. Losses cannot be offset against gains from other categories of income, nor carried forward to future years. This is a significant limitation compared to conventional capital gains tax frameworks.

Record keeping

Taxpayers must be able to demonstrate the value of their crypto holdings on 1 January each year. This requires maintaining records of wallet balances, exchange holdings, and the euro values of assets at that specific date. Records should be retained for at least seven years to satisfy potential audits by the Belastingdienst.

Income Tax Rules

Certain forms of crypto activity fall outside Box 3 and are taxed under Box 1 as ordinary income.

The Belastingdienst identifies three primary situations where this applies. First, if an employer pays salary in cryptocurrency, the employer must convert the value into euros at the time of receipt and report it on the employee’s salary certificate. The employee pays income tax at their normal marginal rate. 

Second, if an individual is considered to be day trading, the regularity and commercial nature of the activity means profits are classified as income from work rather than passive investment returns. Third, operating a crypto mining business on a commercial basis is taxed under Box 1.

Box 1 income tax rates for 2026 are progressive: income up to €38,883 is taxed at 35.75%; income between €38,883 and €78,426 is taxed at 37.56%; and income above €78,426 is taxed at 49.5%. The distinction between Box 3 (passive asset holding) and Box 1 (active trading or professional activity) is determined by the Belastingdienst on a case-by-case basis, considering factors such as the frequency of transactions, the degree of activity, and whether profit-making is the primary intent. Taxpayers uncertain about their classification should seek professional advice.

As of 2026, the Belastingdienst has not issued specific guidance on DeFi activities such as yield farming or liquidity provision. These assets will generally fall under Box 3, though some transactions with an income character may be assessed under Box 1. Taxpayers engaging in DeFi should consult a qualified Dutch tax adviser.

Mining and Staking Treatment

Mining

Mining cryptocurrency in the Netherlands is assessed on the basis of whether it constitutes a hobby or a commercial business activity. 

The Belastingdienst considers several factors in making this determination, the degree and regularity of activity, the consistency of profit, and the level of commerciality of the operation. A casual or small-scale miner whose activities do not amount to a business will be taxed in the same way as any other crypto asset holder, meaning their mining proceeds form part of their Box 3 asset balance at the relevant year-end date.

Where mining is carried out on a commercial basis and generates consistent profits, the activity is classified as self-employment income under Box 1. The fair market value of mined coins in euros at the date of receipt is included in assessable income. Business miners may deduct legitimate expenses such as hardware depreciation and electricity costs against their Box 1 income. The subsequent disposal of mined coins held in a business context would trigger Box 1 income treatment on any gain at the time of sale.

Staking

The Belastingdienst has not issued detailed specific guidance on staking rewards. 

Based on the general framework, staking rewards received as a passive return on holdings are likely to form part of a taxpayer’s overall Box 3 asset base, contributing to the value declared at 1 January each year. Where staking is operated as a commercial service, it may be assessed under Box 1. 

As of 2026, the Netherlands has not published specific rules addressing delegated staking, liquid staking, or DeFi-based staking mechanisms, and taxpayers should take professional advice on the treatment of returns from these activities.

NFT Taxation

NFTs are not addressed by a specific Dutch legislation. 

Under the general framework, an NFT held as a personal investment would be treated as an asset within Box 3, forming part of the total portfolio value declared at 1 January each year. The same notional return calculation and 36% rate would apply to the extent the total asset base exceeds the annual tax-free threshold. Where an individual creates and sells NFTs commercially, this would constitute business activity and be subject to Box 1 income tax on the proceeds.

For NFT creators generating consistent income from the sale of digital artwork or collectibles, the activity is likely to be classified as self-employment under Box 1, with the sale price included in gross income and taxable at progressive rates. Documented costs of creation may be deductible against that income. 

The VAT position of NFT sales in the Netherlands is complex and depends on whether the NFT grants access to a service (which may be VAT-able) or represents a transfer of a digital asset.

As of 2026, the Netherlands has not issued definitive guidance on the VAT treatment of NFTs, and sellers operating at a commercial scale should seek specific advice.

Reporting Requirements

Dutch taxpayers report their crypto holdings as part of their annual income tax return, filed through the online portal MijnBelastingdienst. 

The tax filing season opens on 1 March each year, and the deadline for submission is 1 May. Crypto assets must be declared under Box 3 at their value as of 1 January of the relevant tax year. If any crypto activity triggers Box 1 income, that must also be reported in the income section of the return. 

There is no separate crypto-specific form; crypto is declared alongside other assets and income categories within the standard annual return.

Euro conversion is required for all declared values. Taxpayers must use the market value of their crypto holdings in euros at 00:00 on 1 January of the tax year. For widely traded assets such as Bitcoin and Ethereum, exchange rates from major platforms are accepted. For less liquid tokens, the taxpayer must use the best available market price at that date.

Under the EU’s DAC8 directive, which entered into effect on 1 January 2026, all crypto asset service providers operating within the EU are required to share customer data with the relevant tax authority. Dutch crypto exchanges are legally obliged to provide customer transaction history to the Belastingdienst upon request. 

This applies to both large and small exchanges, and taxpayers should not assume that the absence of a formal statement from their exchange means data is not being shared. Under anti-money laundering obligations, platforms are also required to maintain KYC records.

Taxpayers must retain records sufficient to demonstrate the euro value of their crypto holdings at 1 January each year, as well as any transactions relevant to Box 1 income calculations. 

This includes wallet statements, exchange account summaries, transaction histories, and any records showing the basis on which euro values were determined. A retention period of at least seven years is advisable to cover the standard statutory assessment period.

Penalties

Where a taxpayer has not reported Box 3 assets, including crypto, the authority may raise an additional assessment and charge a fine. Administrative penalties for negligent underreporting typically range from 25% to 50% of the underpaid tax. In cases involving deliberate concealment or fraud, penalties can reach 100% of the unpaid amount or higher, and the Belastingdienst may refer matters for criminal prosecution.

Interest (belastingrente) accrues on unpaid tax from the date it became due. The rate is set periodically and can add significantly to an outstanding liability if a correction is raised several years after the fact. Assessments can in principle be raised up to five years after the end of the relevant tax year, and up to twelve years where the Belastingdienst suspects deliberate evasion involving foreign assets.

Taxpayers who have not previously declared crypto assets have the option of voluntary disclosure. Approaching the Belastingdienst proactively, before they initiate an inquiry, will generally result in lower penalties than corrections made after enforcement action has begun. Dutch accountants are actively advising clients to bring their crypto reporting into order, particularly given the expanded data-sharing powers available to the Belastingdienst under DAC8.
