Just the sticker price. No commas needed.

STEP 1

1. Enter the original price

Type the regular, full pre-discount price of the item.

Discount First, Then Tax

At checkout, the discount comes off first. Ohio sales tax is then charged on the lower, discounted price—not the original sticker price. That order matters massively. Taxing the full price and then discounting it would overstate your tax. Apply the percentage off, then multiply that lower result by your county's combined rate.
Discounted Price = Price × (1 − Discount%)
Total = Discounted Price × (1 + Combined Rate)

Example: Let's look at the numbers. A $100 item at 20% off in Franklin County (8.00%) drops to $80, then adds $6.40 in tax for an $86.40 total. If they taxed the $100 first, you would pay $88.00. That $1.60 difference is why the math order matters.

Worked Examples

$100, 20% off, Franklin (8.00%)$80 × 1.08$6.40 tax → $86.40 total
$250, 30% off, Butler (6.50%)$175 × 1.065$11.38 tax → $186.38 total
$60, 50% off, Cuyahoga (8.00%)$30 × 1.08$2.40 tax → $32.40 total
$1,200, 15% off, Lucas (7.75%)$1,020 × 1.0775$79.05 tax → $1,099.05 total

Final total on a $100 item at 8.00% as the discount grows.

Quick facts

  • Ohio sales tax is legally required to be charged on the discounted price, not the original sticker price.
  • Store coupons and percent-off sales both reduce the taxable amount.
  • A lower discount on a high tax rate can still beat a higher discount on a low rate—always run the numbers.
  • Exempt items like groceries stay at $0 tax no matter what the discount is.
  • Manufacturer rebates do NOT reduce the taxable amount in Ohio. The tax hits the pre-rebate price.

Frequently asked questions

After. The discount reduces the price first, and Ohio sales tax is then charged on that newly discounted amount. So a percent-off sale also effectively lowers the tax you pay.

Multiply the original price by one minus the discount to get the sale price. Then multiply that result by one plus your county's combined tax rate. Our calculator handles both steps instantly.

Yes. A store discount or store coupon that reduces the actual selling price also reduces the taxable base amount, meaning your sales tax bill drops alongside the price.

Use the combined rate for the exact county where you take possession of the item. That means your delivery county for online orders, or the store's physical county if shopping in person.

Exempt items such as groceries and prescription drugs carry absolutely zero sales tax anyway. The discount simply lowers the price, and your final total will exactly equal the discounted price.
