Got a total with tax baked in? Split it.
Receipts and out-the-door prices often hide the tax. Enter the gross amount and the rate you already use; see pre-tax price and tax portion. Or flip the mode to add tax onto a listed price.
We don’t look up ZIP codes or scrape rate tables — sales tax rules vary by place and product. This is for sellers reconciling numbers, not a car-tax or nexus lookup.
What the receipt says
You type the rate — we don't look up ZIP
Sales tax is not your revenue. You're holding it for the state — don't spend it.
Estimates only — not tax or accounting advice. Confirm your rate with your state before filing.
How it's calculated
A customer paid $54.00 out the door and your rate is 8%. The tax isn't 8% of $54 — it's baked into that total. Divide instead: 54 ÷ 1.08 = $50.00 was the product.
That leaves $4.00 of tax. So on your books, $50 is a sale and $4 is money you owe the state — never mix the two.
pre-tax = gross ÷ (1 + rate ÷ 100) tax = gross − pre-tax
