I got a creator code in Fortnite, but have to create a control profile. Does that mean that I have to pay taxes or is that just for some information?
Depending on how you mean it:
You are well known, have received your own code, then you have to enter your tax profile in order to tax the income that you can receive.
If you have entered a creator code from a known person, the tax profile should not have to be entered.
