Cryptocurrency in Belgium: taxes, categories and supervision
In short. Belgium has no crypto statute of its own. MiCA supplies the rules and the markets authority supervises, so the questions that decide what a Belgian holder owes are tax questions. They turn on conduct. The tax office sorts you into one of three boxes, and from 1 January 2026 even the mildest box carries a 10% charge above a 10,000 euro allowance.
- PRUDENT HOLDER
- 10%on gains above 10,000 euros a year
- ANNUAL ALLOWANCE
- 10,000 eurosfor the prudent holder
- SPECULATIVE
- 33%as miscellaneous income
- PROFESSIONAL
- Up to 50%progressive scale
- GAINS BEFORE 2026
- Untaxedonly gains after 31 December 2025 count
Three boxes, one question
Belgian tax law has long sorted an investor by behaviour rather than by asset. A prudent private holder, the goede huisvader, invests as an ordinary careful person would. A speculator takes positions that depend on timing and risk. A professional trades as an occupation. The same bitcoin produces a different bill depending on which description fits.
The tax office weighs how often you trade, how much you commit, whether you borrowed to do it, how long you hold and how much of your income depends on it. No single factor decides, which is why the boundary is argued rather than calculated.
What changed in 2026
The prudent holder used to pay nothing at all. From 1 January 2026 a 10% solidarity contribution applies to realised gains, and the Chamber of Representatives approved the law on 3 April 2026. The charge covers shares, bonds, funds and derivatives alongside crypto-assets, gold and foreign currency.
Two details soften it. The first 10,000 euros of gains in a year stay exempt. And only the gain accrued after 31 December 2025 counts, so value built up before that date is left alone.
Speculative activity still produces miscellaneous income at 33%, and a professional still meets the progressive scale, which reaches 50%.
Supervision
The financial services and markets authority supervises providers under the European framework. MiCA sets the licence, and a provider authorised in another member state may serve Belgian clients on that licence.

- Buy, hold and sell crypto
- Realise up to 10,000 euros of gains a year with no charge as a prudent holder

Restricted

How the rules took shape
A prudent private holder pays nothing on a gain; speculation meets 33% and professional trading the progressive scale.
A 10% solidarity contribution starts on realised gains, with a 10,000 euro annual allowance for the prudent holder.
The Chamber of Representatives approves the law.
Common questions
Is crypto legal in Belgium?
Yes. Belgium applies the European framework, and the financial services and markets authority supervises providers. There is no separate Belgian crypto statute.
How much tax will I pay?
It depends on which category fits you. A prudent private holder pays 10% on gains above 10,000 euros a year. Speculative activity meets 33% as miscellaneous income. Trading as an occupation goes on the progressive scale, which reaches 50%.
Did prudent holders used to pay nothing?
Yes, and that ended on 1 January 2026. The new 10% contribution replaced the full exemption.
Are my older gains taxed?
No. Only the gain accrued after 31 December 2025 falls under the new charge, so value built before that date stays outside it.
How is my category decided?
The tax office weighs frequency, the size of your commitment, borrowing, holding period and how much of your income depends on it. No single factor settles it.
