Do you have it checked? To my understanding backup witholding is for people who owe money to the IRS. Google will take 31% of their income and send it to the IRS to fill that debt, if you have no debt, then you are exempt? Any feedback would be appreciated.
I think only US citizens can do that, but not sure. Anyway, if you are then you should decided whether you want to owe money to the IRS at the years end, or have them owe you.
That's correct. Backup withholding is if you have a prior obligation to the IRS. You will get a 1099 at the end of the year, and that gets reported to the IRS. You should be making estimated quarterly payments at least equal to your self-employment income of last year to avoid a penalty.
