Key Takeaway
No matter where you shop or what you buy, the reverse sales tax calculation follows the same formula:
Original Price = Total Price ÷ (1 + Sales Tax Rate)
The only value that changes is the applicable sales tax rate, which depends on the state and, in many cases, the county or city where the purchase occurred. Using the correct combined tax rate ensures you accurately separate the item’s pre-tax price from the tax included in the total.
