HOW THE CALCULATION WORKS

What is reverse sales tax?

Reverse sales tax removes the tax from a final receipt total so you can see the original price and the tax amount separately.

A simple way to read your receipt

When a receipt shows one final amount, the price and the tax are already combined. Enter the total and the rate to separate them.

Start with total paid

Use the amount printed as the final receipt total.

Use the right rate

A combined state and local rate gives the closest receipt check.

Read both amounts

The result shows the price before tax and the tax included in the total.

RECEIPT EXAMPLE07.25

Price before tax$100.00

Sales tax$7.25

Total paid$107.25

Rate used 7.25%

Price before tax$100.00

Formula107.25 divided by 1.0725 equals 100.00

Rate noteA state rate is a starting estimate. Use the combined rate on the receipt when possible.

How it works

Three short steps take you from a receipt total to the amount before tax.

Enter the total

Type the tax-inclusive amount printed on the receipt.

Confirm the rate

Use a state estimate or enter the combined rate from the receipt.

Read the result

See the price before tax, the tax amount, and the total.

The reverse sales tax formula

Use the same calculation by hand or in a spreadsheet.

Pre-tax price = Total price divided by (1 plus tax rate)

Example: $107.25 divided by 1.0725 gives $100.00 before tax.

Other tools

Use a second tool when your question is about adding tax, comparing states, or checking a receipt.

Examples by state

These examples use state rates. Local rates can change the result.

California

State rate 7.25 percent

$107.25 divided by 1.0725 = $100.00

Enter the combined rate from your receipt when local tax is included.

Texas

State rate 6.25 percent

$106.25 divided by 1.0625 = $100.00

Local rates can raise the combined rate above the state rate.

New Jersey

State rate 6.625 percent

$106.625 divided by 1.06625 = $100.00

Check the transaction details when a special local rule may apply.

Check a receipt

Compare the tax charged with the rate you enter. This is a general check, not a tax decision.

QUICK ANSWERS

Questions about the calculation?

Short answers to the questions people ask before using the calculator.

How do I remove sales tax from a total?

Divide the tax-inclusive total by one plus the tax rate written as a decimal. The result is the price before tax.

Should I use a state rate or a combined rate?

Use the combined state and local rate on the receipt when you need to check a specific purchase. A state rate is a starting estimate.

What is the formula?

Pre-tax price equals total price divided by one plus the tax rate. Tax amount equals total price minus the pre-tax price.

Can I use the calculator for a business receipt?

Yes. Enter the tax-inclusive total and the rate that applies to the transaction. Keep the receipt and confirm the rate before using the result for formal records.

Why can my result differ by a few cents?

Merchants may round tax at the item level or at the order level. A small difference does not always mean the rate is wrong.

Which states have no statewide sales tax?

Alaska, Delaware, Montana, New Hampshire, and Oregon have no statewide sales tax. Some local areas may still charge a local tax.

Can I use the result as tax advice?

No. The calculator provides a general estimate. Confirm rates with the relevant tax authority or a qualified professional for formal decisions.
