Question in title - basically, is there any way to legally receive money in EU for some digital service / product without opening some sort of trade / LLC?<p>We can say I'm specifically asking for Belgium.
Almost all tax collectors let you earn up to a certain amount per year before you have to make it a business. It can be as high as €20 000. Talk to an accountant or the business bureau in your region. They usually have very accessible information on their websites.
Yes, in Belgium and most of the EU, you can earn small amounts legally. You can do this through a “side income” or hobby income model without having to register a business right away.<p>Like that, use platforms like Ko-fi, Gumroad, or Buy Me a Coffee, which handle payments and taxes partially.<p>If your income stays below a certain limit of about €6,000 a year in Belgium through the deeleconomie scheme, you could get tax benefits. And you won’t need full business registration.
