Crypto Tax in Belgium 2026: 10% Rate, Forms & Deadlines

Taxation of cryptocurrencies in Belgium

In Belgium, capital gains on cryptocurrencies are subject to tax. The calculation method used is FIFO with a rate of 10%. Understanding these rules is essential to stay compliant with tax legislation.

The FIFO method explained in detail

The FIFO (First-In-First-Out) method matches each sale with the oldest lots still held: the gain is the difference between the sale price and the purchase price of those lots. FIFO only sets the order in which lots are matched. What is taxable (sales, crypto-to-crypto swaps), the rate and any exemptions depend on the rules of Belgium detailed in this guide.

Taxable events

• ●Sale of crypto for fiat currency (EUR, USD...)
• ●Payment for goods or services with cryptocurrencies
• ●Crypto-to-crypto swap (e.g. BTC → ETH)
• ●Converting to a stablecoin (USDT, USDC…)
• ●Staking rewards: treatment not documented for this country (income on receipt or tax on sale, depending on classification)
• ●Airdrops and free tokens: treatment not documented for this country
• ●Mining income: taxable as business income or miscellaneous income
• ●Crypto-to-crypto exchange (in some countries only)
• ●Transfer between your own wallets
• ●Holding (HODL): holding without selling does not create any tax obligation (except in the Netherlands, Box 3)

Tax declaration procedure in Belgium

You must declare your crypto capital gains on the following forms: Déclaration IPP. We recommend keeping the complete history of your transactions as proof.

Exemption thresholds and allowances

In Belgium, an annual exemption of 10 000€ applies to your capital gains: only the part of your gains for the year above this amount is taxable. Even below the threshold, filing a return may still be required. For comparison, other countries instead exempt gains based on the holding period: 12 months in Germany, 3 years in Czechia, 365 days in Portugal.

Deadlines and tax calendar

Each country has its own tax filing deadlines. Filing and payment dates in Belgium are set each year by the tax authority and may vary with the filing method. Check the official calendar for the year concerned. We strongly recommend preparing your crypto tax return in advance with Taxes Crypto rather than waiting until the last moment.

Penalties for non-declaration

Failing to declare your crypto capital gains can lead to significant penalties: tax surcharges, late-payment interest, and in serious cases, criminal prosecution for tax fraud. In the EU, the DAC8 directive gives tax administrations platform data on transactions made since 2026 (first exchanges by 30 September 2027 at the latest), which makes audits easier.

Tax treatment of crypto-to-crypto exchanges

In Belgium, a crypto-to-crypto swap (e.g. BTC → ETH) is a taxable event: the gain is computed at each swap, even without converting to fiat. Every transaction must therefore be tracked and valued.

NFTs, DeFi and derivatives

In Belgium, the 10% rate shown in this guide applies to disposals of crypto-assets; whether it applies to NFTs, DeFi income and derivatives depends on how they are classified, which is not documented here for each case. Regularly creating or selling NFTs may amount to a business activity.

Obligation to declare crypto accounts and wallets

In Belgium, check whether digital-asset accounts opened with platforms established abroad must be reported: where it exists, this obligation is separate from reporting your gains. The DAC8 directive is an obligation on platforms: it does not replace your own returns.

Specific tips for Belgium

Crypto taxation in Belgium has certain specificities that are important to know. The FIFO calculation method imposes a precise logic for determining the order of disposals. Investors should be particularly vigilant about the following: crypto-to-crypto exchanges may be taxable depending on the jurisdiction, airdrops and hard forks have specific tax treatment, and staking or mining income is generally considered taxable income upon receipt. In case of a change of tax residence, the rules of your new country apply for future transactions, but unrealised gains may be subject to an exit tax in certain cases. Consult a tax professional if your situation is complex.

Frequently asked questions about crypto tax in Belgium

Crypto investors in Belgium often have the same questions. Do I need to declare if I haven't sold? Generally, simply holding crypto assets is not taxable, but some countries require a wealth declaration. What happens if I forgot to declare in previous years? Most tax administrations allow voluntary regularisation, often with reduced penalties. How are NFTs taxed? Their tax treatment depends on the right attached to the token and is not always that of cryptocurrencies. The applicable rate in Belgium is 10%, and the required forms are: Déclaration IPP. Taxes Crypto automatically generates a report compatible with these forms to simplify your declaration.
