How to calculate sales tax

Tax = Price × (Rate ÷ 100) | Total = Price + Tax

Example: $75 at 8% → $6.00 tax → $81.00 total.

States with no sales tax

Alaska, Delaware, Montana, New Hampshire, and Oregon have no state-level sales tax.

Reverse calculation

To find pre-tax price from a total: Pre-tax = Total ÷ (1 + Rate). Example: $108 at 8% → $108 ÷ 1.08 = $100.
