do i have to pay on a 1099g?

Answer 1

If this is a state income tax refund, it is taxable only to the extent that the deduction reduced taxable income in the earlier year.

If you didn't itemize then the state income tax refund isn't taxable. Otherwise, the portion of the refund that is above standard deduction is taxable.

Best wishes.

Answer 2

Yes you do, depending on what the 1099 G is for there is a line on the forrms for if it is for unemployment, if it is for state refund of prior year taxes you would only report that if you itemized your deductions in the prior year and claimed the state tax deduction.
