What Is Reverse Sales Tax?

This is useful for expense reports, reimbursements, and understanding exactly how much tax you're paying on a purchase.
How to Calculate Reverse Sales Tax
The formula for reverse sales tax is:
Pre-Tax Price = Total ÷ (1 + Tax Rate)
Tax Amount = Total – Pre-Tax Price
Where Tax Rate is expressed as a decimal (e.g., 7% = 0.07)
Example: If you paid $107.00 total and the sales tax rate is 7%:
- Pre-Tax Price = $107.00 ÷ 1.07 = $100.00
- Tax Amount = $107.00 – $100.00 = $7.00
