Reverse Sales Tax Formula: Selling Price = Final Price / 1 + Sales Tax

Reverse Sales Tax Definition
Have you ever wondered how much you paid for an item before the sales tax or if the sales tax on your receipt was correct? Now you can find out with our “Reverse Sales Tax Calculator.”
Our “Reverse Sales Tax Calculator” accepts two inputs. All you have to input is the amount of sales tax you paid and the final price on your receipt.

For Example:
If your total receipt amount was $57.98, and you paid 1.07 percent in sales tax, you’d simply plug those numbers into our calculator to find out that your original price before tax was $57.37. From there, it is a simple subtraction problem to figure out that you paid .61 cents in sales tax.
The only thing to remember in our “Reverse Sales Tax Calculator” is that the top input box is for the sales tax percentage, and the bottom input box is for the total purchase price.

Why A “Reverse Sales Tax Calculator” is Useful
A “Reverse Sales Tax Calculator” is useful if you itemize your deductions and claim overpaid local and out-of-state sales taxes on your taxes. The only thing to remember about claiming sales tax and tax forms is to save every receipt for every purchase you intend to claim.
Most states and local governments collect sales tax on items that are sold in stores. For some individuals, knowing how much sales they paid is essential for filling out correct tax returns and receiving monetary credit for overpaid sales tax. This is especially beneficial if you have to list your out-of-state purchases to you current state of residence and the taxes paid on those purchases.
