Show the working
- Price before tax = 100
- Sales tax rate = 4.875
- Or a price that already includes tax = 107.25
- Quantity = 1
- Tax added = 100 * 4.875 / 100 = 4.875
- Total with tax = 100 + 4.875 = 104.875
- Total for the quantity = 104.875 * 1 = 104.875
- Price before tax, working backwards = 107.25 / (1 + 4.875/100) = 102.265
- Tax inside a tax-inclusive price = 107.25 - 102.265 = 4.9854
- Tax as a share of the total = 104.875 > 0 ? 4.875 / 104.875 * 100 : 0 = 4.648 39
- Multiply the net price by this = 1 + 4.875/100 = 1.048 75

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.
