Much as I hate to be the bearer of bad news, you're not done paying taxes yet. They don't do a great job explaining this, but you'll get a 1099 from the show early next year. You'll have to report that on your 1040 and state tax returns, so what you won on the show is added to the income you make from other sources and is taxed as if you had made it at a job. To give an example, let's say your total income, excluding
TPiR, is $50,000. Given you won $30,727 on the show, your total income is now $80,727. Here's how it will break down by type of tax:
Federal tax: Assuming you're single and take the standard deduction of $12,400, the federal tax burden on $50,000 is $4,315. The federal tax burden on $80,727 is $10,822. Your job will still assume you're only making $50,000, so you'll be on the hook for the extra $6,507 by April 15 of next year, plus possibly a penalty for under-withholding your tax by too much. (You may want to increase your withholding at work or look into an
estimated tax payment to avoid that penalty.)
CA tax: CBS took 7% out of your winnings for CA tax, but that was just for estimated tax. You'll need to file a
non-resident CA return next year and you'll likely get some of it back. Going back to my example, assuming you're single and take CA's standard deduction, you'd really owe CA $1,573 in tax. Since CBS withheld $2,151, you'd get $578 back from CA. (Again, this all assumes you make $50,000 pre-
TPiR and file as a single person.)
NJ tax: I've never dealt with NJ tax, so I have to keep this general. Fill out the CA non-resident tax form first. Then you should be able to take a credit for the actual tax you owed to CA (not the amount CBS withheld), so your NJ tax shouldn't increase or shouldn't increase by much. You may need to submit a copy of your CA tax return to prove to NJ you paid that tax.
Source: I do my own taxes and had to deal with this last year, except it was UT tax for me instead of NJ tax.
Disclaimer:
I am not an accountant. Even if you make exactly $50,000, you should still run all calculations yourself (and/or use tax software and/or consult an accountant) and check my work. I'm just trying to give you an idea of what you're in for.
