- Price before tax = 100
- Sales tax rate = 6
- Or a price that already includes tax = 107.25
- Quantity = 1
- Tax added = 100 * 6 / 100 = 6
- Total with tax = 100 + 6 = 106
- Total for the quantity = 106 * 1 = 106
- Price before tax, working backwards = 107.25 / (1 + 6/100) = 101.179
- Tax inside a tax-inclusive price = 107.25 - 101.179 = 6.070 75
- Tax as a share of the total = 106 > 0 ? 6 / 106 * 100 : 0 = 5.660 38
- Multiply the net price by this = 1 + 6/100 = 1.06
Values are shown to six significant figures here; the arithmetic itself runs on exact fractions and is only rounded where a number is printed.

The formula
- tax = price x rate
- total = price x (1 + rate)
- to remove tax: net = gross / (1 + rate), never gross x (1 - rate)
Removing a tax is division, not subtraction. Taking 7.25% off a tax-inclusive price undercharges you every time.
Rates change and local additions vary by address. Treat the prefilled rate as a starting point and check the current combined rate for the exact jurisdiction.
Clothing and most groceries are exempt.
