Now California is a ‘gem’ on taxes. Let's say he moved before this weekends tournament in San Diego. Assume he just barely makes the cut and earns $1000 dollars.
Next say this is the only money he earned in California in the year.
Does he get taxed at the rate of earning $1000 dollars on his California taxes, No he gets taxed at the max rate. He must show his total earnings for the year $100 million, add the $1000 then tax the $1000 dollars at the $100 million rate.
Honestly it's not that simple as the State of California believes in the 5 days he is there at the tournament the endorsement money should also be taxed at 5/365 for the money earned in California.
It insidious.
