I have a question. I received an affiliate registration form from Twitch, my question is will it expire? Because I still have to inquire about taxes etc.
The invitation is not known to expire.
But if you choose Twitch Affiliate, you transfer rights & sign an exclusive contract! From which Twitch first benefits, not the streamer.
You also have to register a business & what you need to know about tax:
If you stay below 22,500 euro (turnover) a year, it is enough to send an EÜR to the tax office once a year. Preferably via ELSTER. Familiarize yourself with the subject of "small business regulation".
