So don't I simply take my AGI x .0725?
Most of your AGI is used to pay for things that are NOT subject to Sales Tax. The IRS isn't going to give you a sales tax deduction for things that you don't pay sales tax.
You don't pay sales tax on your mortgage/rent, real estate tax, income tax, charitable contributions, etc. State laws vary, but often some food, clothing, and many other things are not subject to sales tax.
