I m12 want to earn some money!
Since I'm very good at video games, I wondered if I could teach it to others too.
Do you have to pay taxes if you are e.g. Fortnite or COD trainer?
Do you have to register a business or something? And if so, can you do that as a minor, with parental permission?
At 12 you are not yet legally competent and are not allowed to work. Please have a look at the JarbSchG.
If you register it as a business, yes. But first find someone who needs a trainer and is even willing to pay him. 😂
First try to find someone who will accept you as a game coach and pay money for it. How should the money get to you?
If you've earned the first 50 euro, and maybe within 1 month, I would wait another 12 months to see how it all develops. At a stable 50 euro per month it would be 600 euro. I would now consider asking the question again.
Age doesn't matter at all, there's always a corresponding business structure.
I can't imagine anyone needing a computer game coach. Especially not someone who also charges money for training. Where do the children get the money for such a trainer?
