When to Use a Reverse Sales Tax Calculator
A reverse sales tax calculator is useful when:
- Reconciling receipts — Determine the pre-tax subtotal and tax amount from a tax-included total on a receipt.
- Expense reports — Separate the tax portion from business expenses for accurate reimbursement or tax deduction claims.
- Budgeting — If a store lists prices with tax included, figure out what you're actually paying for the item vs. the tax.
- Price comparisons — Compare items fairly when some prices include tax and others don't.
Just enter the total from your receipt and the sales tax rate for your area. The calculator instantly shows the price before tax and exactly how much tax was charged. If you need to go the other direction — add tax to a price — use our main Sales Tax Calculator.
