But that is the case with anyone earning income, especially 1099 income. Typically it is taxed where it is earned. What will be interesting is if some state with an income tax decides to tax income earned by players from another without one for games played in the tax state. If I understand it correctly that happens in professional sports. Now this might be different since the player might argue he isn’t being paid for play, but I suspect it will happen.
We really don't want to be the State that does this.
For most athletes it will be a 2-3 minute inconvenience on their federal taxes. A state can only tax you on the portions n of the income you earn in that state.
So, if a kid makes $24k and plays 1 of their 12 games in CT it's only 1/12 of their pay which gets taxed- $2k.
And this should only matter if the player earns income directly from the school. Endorsements can be different.
I have to do the same with my work. I live in a state with no income tax but if I travel to other states I have to show a change in work location on our labor charging system. If I go over a certain income threshold or days of work threshold, I'll get hit for state taxes. My company fully pays my taxes as a separate pay stub and I have to file state taxes for that state or states at end of year.
The difference for NIL is if say a Florida kid on UConn ends up with a deal for a car dealership in Miami. Is income considered earned in Florida because of location of dealership or is it earned in CT because the deal was based on kid playing football in CT. I'm sure this is an easy tax question, I just don't know the answer.
