Twitch Affiliate? - 2

Does it matter if I give my father's tax number (tax ID) on Twitch or is that a criminal offense

No, you have to provide your tax ID. After all, it's you who registered the necessary trade, right?

After all, you are of legal age and you know how to tax the profits made, right?

Yes, no, I'm still 15, but everything has been clarified for me by my parents. I'm on twitch 15 too and I'm not working yet
