### Why is it Beneficial to Use a “Reverse Sales Tax Calculator”?

If you itemize your deductions and claim overpayment of local and out-of-state sales taxes on your taxes, a “Reverse Sales Tax Calculator” can help. The essential thing to keep in mind when it comes to claiming sales tax and tax forms is to keep all receipts for any purchases you wish to claim.

On things sold in stores, most states and municipal governments collect sales tax. For some people, knowing how much sales tax they paid is critical for filing accurate tax returns and seeking a refund for sales tax overpayments. This is especially useful if you need to report your out-of-state purchases and the taxes you paid on them to your present state of residence.

### Calculate the sales tax backwards from total

When reviewing your business receipts, for example, you might want to know how much is genuine income and how much is sales tax.
To compute sales tax backward from the total, use the formula below.
We’ll assume you already know the sales tax percentage in this computation.
Add the sales tax percentage to your sales revenues and multiply by 1.
The total sales-tax dollars are calculated by multiplying the result by the tax rate.
To calculate your non-tax sales revenue, subtract that amount from your receipts.

### Reverse Sales Tax Formula:

Selling Price = Final Price, 1 plus Sales Tax

For Instance, assume your sales revenues totaled \$1200, and your sales tax rate is 12%.
Sales tax is \$ 129
