How long before you can receive credit for sales tax after you've written it off?

Answer 1

You can't write off sales tax. I am guessing you mean you've written off collection of the money from whatever you sold. IF you can claim a credit for sales tax at all, the rules would vary by state.

Answer 2

If you itemized deductions and deducted sales tax instead of state and local income taxes, your total tax on your return would have been decreased.

Answer 3

I don't understand the question. What kind of credit, and writing it off? Please clarify.
