Are cryptocurrencies taxable? In Belgium, there are three cases:
1- You are a "novice"
You invest in cryptocurrencies as a hobby or a test investment, then your investments are exempt from taxation. However, the conditions are that you take few risks and you make long-term investments (we’re talking about several years).
2- You are a private trader
You take risks with your investments in cryptocurrency and you buy and sell them regularly with the aim of making a short-term profit. You must declare your profits from buying and selling cryptocurrency in your tax return as diverse income and it will be subject to 33% tax.
3- You are a professional trader
Trading cryptocurrency is your main job. You must then apply the rules that apply to all self-employed people: you must declare your cryptocurrency income in your tax return and your net annual income will be subject to progressive income tax (between 25 and 50%).
