1. What is Reverse Sales Tax Calculation?

Reverse sales tax calculation determines the original price of an item before tax was added, given the total amount paid including tax. This is particularly useful for business accounting, expense reporting, and financial analysis.

2. How Does the Calculator Work?

The calculator uses the Texas sales tax formula:

Where:

• Total Amount — Final price including Texas state sales tax (USD)
• 0.0625 — Texas state sales tax rate (6.25%)

Explanation: The formula works backward from the total amount to determine how much of that total was the original price versus the tax amount.

3. Importance of Reverse Tax Calculation

Details: This calculation is essential for businesses to properly account for expenses, for individuals tracking pre-tax costs, and for accurate financial reporting where only the tax amount needs to be claimed.

4. Using the Calculator

Tips: Enter the total amount paid (including tax) in USD. The calculator automatically uses the Texas state sales tax rate of 6.25% (0.0625).
