Crypto Tax in Belgium 2026: The New 10% Tax and €10,000 Exemption Explained

For years, Belgium was one of the friendliest places in Europe to hold Bitcoin: if you managed your crypto like a "good parent" (normal management of private assets), your gains were usually tax-free. That changed on 1 January 2026. If you are searching for how crypto tax in Belgium 2026 works, the short version is this: realised gains are now taxed at 10%, but only above an annual exemption of €10,000 per person, and only on value gained after 31 December 2025. This beginner guide explains the new rules, what counts as a taxable event, and what to prepare before your first return in 2027.

Crypto tax in Belgium 2026: what changed

The Belgian Chamber approved the new capital gains tax on financial assets on 2 April 2026. It was published in the Belgian Official Gazette on 21 April 2026 as the Law of 6 April 2026 and applies retroactively from 1 January 2026. The tax administration (SPF Finances / FOD Financiën) lists cryptocurrencies explicitly among the "financial assets" covered, next to shares, bonds, ETFs and investment gold.

The key numbers for a private investor are:

Rate: 10% on realised capital gains.
Annual exemption: the first €10,000 of gains per person (amount for tax year 2027, indexed over time).
Carry-forward: if you don't use it, up to €1,000 of the exemption can move to the next year, for up to 5 years, to a maximum exemption of €15,000.
Per person: partners filing a joint return each get their own exemption.

Before 2026, the 33% "miscellaneous income" rate for speculative trading already existed. It has not disappeared. The new 10% regime covers normal management; speculative or abnormal management can still be taxed at 33%, and professional trading at progressive rates.

The 31 December 2025 "photo" moment

The most beginner-friendly part of the reform is the reference date. For assets you already held before 2026, your tax purchase price is the value on 31 December 2025. In practice, gains built up before 2026 stay untaxed.

If your original purchase price was higher than the 31 December 2025 value (for example, you bought Bitcoin near a peak), you can use the higher historical price instead, as long as you can prove it. Commentators on the official circular 2026/C/74 note that this option runs for sales up to the end of 2030. The minister also indicated that a simple screenshot from your trading platform can, in principle, serve as proof of the 31 December 2025 value. If you haven't saved one, export your exchange history and balances now.

What counts as a taxable event?

This is where many Belgian beginners get caught out. The tax applies to every disposal "for consideration", not only to cashing out into euros. According to the circular as summarised by Belgian tax lawyers, the following apply:

Transaction	Taxed under the 10% regime?
Selling Bitcoin for euros	Yes
Swapping one crypto for another (BTC to ETH)	Yes
Converting crypto into a stablecoin (BTC to USDC or EURC)	Yes
Paying with crypto, including with a crypto debit card	Yes
Moving coins between your own wallets (exchange to hardware wallet)	No
Buying and holding	No
Staking, lending or DeFi rewards	Separate regime: generally taxed as investment income at 30% when received

Every calculation is done in euros, at the market value at the moment of the transaction. That's why a busy year of swapping altcoins can produce a tax bill even if you never withdrew a single euro to your bank.

How to calculate your gain

The basic formula from SPF Finances is simple: gain = sale value − purchase value. Three rules make it less simple:

No costs are deductible. Trading fees and network fees are not subtracted from the gain.
FIFO applies. Coins are treated as sold in the order you bought them (first in, first out).
Losses only count in the same year. Losses can be offset against gains in the same category and tax year, but an unused 2026 loss cannot be carried forward to 2027.

Worked example: Lies held 0.5 BTC worth €40,000 on 31 December 2025. In 2026 she sells it for €52,000. Her taxable gain is €12,000. After the €10,000 exemption, €2,000 is taxable, so she owes 10% × €2,000 = €200. If she had sold for €48,000, her €8,000 gain would sit fully inside the exemption.

Staking rewards: a different rate

Staking, lending interest and yield farming rewards are not part of the 10% capital gains regime. The Belgian ruling service generally treats them as interest-type investment income taxed at 30% at the moment you receive them, valued in euros, with no exemption. Some tax lawyers dispute this position, so it may still be tested in court. If you later sell those rewards, only the rise in value after you received them falls under the 10% tax.

How and when do you declare it?

For shares at a Belgian bank, the 10% can be withheld automatically ("opt-in"). For crypto, tax commentators reading the circular say no withholding applies, so you report gains yourself in your personal income tax return. Gains realised in 2026 go into the return filed in 2027 (tax year 2027).

The tax office will also have more data than before. Under DAC8, EU crypto service providers have had to collect user transaction data since 1 January 2026 and report it to tax authorities, who then share it between member states.

Belgium vs neighbouring countries

Belgium's new model is still mild by European standards. France applies a 31.4% flat tax on crypto disposals into euros (see our France crypto tax guide), while Germany can tax gains at your personal income tax rate unless you hold for more than a year (explained in Bitcoin Taxes in Germany: The One-Year Rule). The Netherlands takes yet another approach and taxes assumed returns on your holdings through Box 3.

Checklist before 31 December 2026

Save proof of every holding's value on 31 December 2025 (screenshots, CSV exports).
Download full 2026 transaction histories from each exchange and wallet app.
Add up realised gains and losses so far; remember losses don't carry into 2027.
Keep staking and lending rewards in a separate list.
If you trade very frequently or with leverage, ask a Belgian tax adviser whether you risk the 33% speculative category.

FAQ

Do I pay tax just for holding Bitcoin in Belgium?
No. Holding crypto is not taxed under this regime. Tax only arises when you realise a gain, for example by selling, swapping or paying with crypto.

Is moving Bitcoin to my hardware wallet a taxable event?
No. Transfers between wallets you own are not disposals. Keep records showing both wallets are yours.

Are gains I made before 2026 taxed?
In principle, no. For assets held before 2026, the value on 31 December 2025 becomes your purchase price, so earlier growth stays outside the new tax.

Important disclaimer

This article is general information, not financial or tax advice. Belgian tax rules are new and some points, such as staking and the line between normal and speculative management, may still be clarified by the administration or the courts. Check your own situation with SPF Finances or a qualified Belgian tax adviser.

Bottom line

From 2026, Belgium taxes crypto gains at 10% above a €10,000 yearly exemption, counting only growth after 31 December 2025. Swaps, stablecoin conversions and crypto card payments all count, fees aren't deductible, and you declare it yourself in 2027. Good records are now your most valuable crypto tool.
