How to Back Out Sales Tax

Sales tax is added on top of a price, so the total is the price multiplied by one-plus-the-rate. To reverse it, you divide the total by that exact same figure to recover the original price, then subtract to find the tax. This is the ONLY correct way. Multiplying the total by the rate overstates the tax, because you end up taxing the tax.
Pre-Tax Price = Total ÷ (1 + Combined Rate)
Sales Tax = Total − Pre-Tax Price
Example:

Let's look at the numbers. A $108.00 total in a county with an 8.00% combined rate breaks down to $108 ÷ 1.08 = $100.00 before tax, leaving exactly $8.00 in sales tax.

Worked Examples

$108.00 total at 8.00% (Franklin)$108 ÷ 1.08$100.00 pre-tax → $8.00 tax
$53.25 total at 6.50% (Butler)$53.25 ÷ 1.065$50.00 pre-tax → $3.25 tax
$214.00 total at 7.00% (Delaware)$214 ÷ 1.07$200.00 pre-tax → $14.00 tax
$1,080.00 total at 8.00% (Cuyahoga)$1,080 ÷ 1.08$1,000.00 pre-tax → $80.00 tax

Quick facts

  • Backing out tax uses division, not multiplication. Multiplying the total by the rate mathematically overstates the tax.
  • The pre-tax price is always smaller than the total divided by the rate alone.
  • Reverse calculations are incredibly common at tax time, for expense reports, and for reconciling shady receipts.
  • Ohio's combined rates run from 6.50% to 8.00%, so the same total hides a different tax amount in each county.
  • Groceries and prescriptions are legally exempt, so a receipt for those has $0 tax to back out.

5 of 5 answered

Divide the total by one plus the tax rate to get the pre-tax price, then subtract that from the total. For an 8% rate: $108 ÷ 1.08 = $100, so the tax is exactly $8.

Was this explanation helpful?

Because the total already includes the tax. Multiplying the total by the rate taxes the tax and gives a number that is way too high. You must divide to remove the tax first.

Was this explanation helpful?

Use the combined state-plus-county rate for the exact county where the sale took place. It ranges from 6.50% to 8.00% across Ohio's 88 counties.

Was this explanation helpful?

Yes. An out-of-state seller or marketplace facilitator shipping into Ohio does source the sale to your delivery address (R.C. 5741.05), so select the county the order shipped to. If the seller is an Ohio business, the rate is the seller's own county instead under R.C. 5739.033(B)(1) — pick that county and enter the total you paid.

Was this explanation helpful?

It is the price the tax was calculated on. If a discount was applied before tax, the pre-tax price reflects the discounted amount, not the original sticker price.
