Do I have to pay tax if I pay a one-off $ 100 on Twitch?

I streamed a bit on Twitch for the fun of it and will soon be at my payout minimum after that I won't be streaming anymore. It's $ 100, should I also pay taxes? (am a minor)

Basically yes. However, I would count that as other income according to §22 EstG

tax exemption at 256 euro

otherwise the basic tax-free amount is 9408 euro. If you have no other income, it remains tax-free until then

§22 Income would be easier and can be met once. Saves a lot of work
