If you elect to deduct state and local general sales taxes, you can use either your actual expenses (see Enter All My Receipts below) or the optional sales tax tables (see EasyGuide below).
EasyGuide - This lets the program guide you through interview to calculate an amount. You'll need your combined total state and local sales tax rate in addition to any sales tax paid on major purchases. Please see How do you define "major purchase" or "major item" for the sales tax deduction? for more information.
Enter All My Receipts - If you have all of your receipts for sales tax paid during the year, you can deduct the total sales tax you paid. But if you are audited (this is not an audit trigger unless it is abnormally large compared to your income), you will be required to produce all of those receipts.
