Ohio Sales Tax Calculator

Ohio's sales tax system is a two-layer structure consisting of a statewide base rate of 5.75% plus a county-level surtax that varies by jurisdiction. Every county in Ohio levies its own surtax on top of the state rate, and these surtaxes range from 0.75% in some counties to 2.25% in Cuyahoga County — home to Cleveland — producing total combined rates between 6.5% and 8.0% depending on where the purchase is made. The county surtax is authorized by state law and set by county commissioners, with changes requiring voter approval through a referendum in most cases.

The most populated Ohio counties and their 2024 combined rates include: Franklin County (Columbus) at 7.5%; Cuyahoga County (Cleveland) at 8.0%; Hamilton County (Cincinnati) at 7.8%; Summit County (Akron) at 6.75%; Montgomery County (Dayton) at 7.5%; Lucas County (Toledo) at 7.25%; and Stark County at 6.5%. Smaller and more rural counties often have lower combined rates because voters have been less willing to approve additional surtax levies. When you make a purchase in Ohio, the applicable rate is determined by the location of the seller, not the location of the buyer — though for remote and online sales, the buyer's county rate typically applies.

Retailers operating in multiple Ohio counties must apply the correct combined rate for each county where sales occur, which can complicate accounting for businesses with locations in several jurisdictions. Ohio's Department of Taxation maintains an online lookup tool where both consumers and businesses can verify the current combined sales tax rate for any Ohio address. This lookup is important because county rates can change when new levies are approved by voters, and the effective date of any rate change must be correctly applied to transactions occurring around the changeover date.

Ohio exempts a substantial range of goods and services from sales tax. Food sold for off-premise consumption — groceries purchased at supermarkets, convenience stores, and similar retail outlets for home preparation — is exempt from Ohio sales tax. This exemption covers most unprepared food items but does not apply to prepared food intended for immediate consumption, soft drinks, alcoholic beverages, or dietary supplements. The line between exempt grocery food and taxable prepared food follows Ohio's definition: food that requires no further preparation by the purchaser for immediate eating is generally taxable.

Prescription drugs and most medical devices prescribed by a licensed health care professional are exempt from Ohio sales tax. Durable medical equipment, prosthetics, and orthopedic devices prescribed for a patient's use are also generally exempt. Over-the-counter drugs and medications — those available without a prescription — are taxable in Ohio, which distinguishes the state from some others that exempt all pharmaceuticals. Industrial machinery and equipment used primarily in manufacturing or processing goods for sale are exempt under Ohio's manufacturing equipment exemption, which is an important provision for the state's significant industrial base.

Agricultural exemptions are broad in Ohio, covering sales of feed, seed, fertilizer, pesticides, and farm equipment used directly in agricultural production. Utilities used in manufacturing and farming — including electricity, natural gas, and water — may be partially or fully exempt depending on the predominant use. Sales to government entities, qualifying nonprofit organizations, and churches for their exempt purposes are also not subject to Ohio sales tax. Ohio also exempts newspapers, magazines sold by subscription, and most services — Ohio taxes relatively few service categories compared to states like Hawaii or South Dakota, which have broader sales tax bases that include most services.

To calculate Ohio sales tax on a purchase, you need two pieces of information: the taxable purchase amount and the combined sales tax rate for the county where the sale occurs. Once you have the combined rate, the calculation is identical to any other percentage-based computation. Multiply the taxable purchase amount by the combined rate (expressed as a decimal) to get the tax amount, then add it to the purchase price to get the total. For example, a $500 appliance purchased in Columbus (Franklin County, 7.5% combined rate) carries $37.50 in sales tax for a total of $537.50.

For transactions that include both taxable and exempt items — such as a grocery run that includes some prepared foods (taxable) and some unprepared foods (exempt) — the tax applies only to the taxable portion of the purchase. Retailers are required to separately identify taxable and exempt items on receipts and to collect tax only on the taxable items. Consumers benefit from reviewing receipts to verify that tax was correctly applied — errors in favor of the retailer (taxing exempt items) or in favor of the consumer (failing to tax taxable items) do occur, and the retailer is ultimately responsible for remitting the correct amount.

Working backward from a tax-included total is straightforward: divide the total by (1 + the combined rate) to find the pre-tax amount. For an $800 total in a county with a 7.75% combined rate, the pre-tax amount is $800 ÷ 1.0775 = $742.20, and the tax is $57.80. This reverse calculation is useful for expense reimbursement, business accounting, and verifying that a quoted price included tax rather than having it added on top. Ohio retailers are not required to include tax in the displayed price — unlike some countries where all prices are shown tax-inclusive — so the stated price is typically pre-tax and the tax is added at checkout.

Ohio's use tax is the companion to the sales tax and applies to purchases made from out-of-state sellers who did not collect Ohio sales tax at the point of sale. The use tax rate equals the combined sales tax rate that would apply in the buyer's Ohio county — the same rate as the local sales tax. Ohio law requires residents and businesses to self-report and pay use tax on taxable goods purchased outside Ohio (or online from retailers without Ohio nexus) when those goods are used, stored, or consumed in Ohio. The use tax ensures competitive neutrality between Ohio retailers, who collect tax, and out-of-state sellers, who formerly could skip the collection obligation.

Following the Supreme Court's 2018 South Dakota v. Wayfair decision, most large online retailers with significant economic activity in Ohio now collect and remit Ohio sales tax automatically. Economic nexus in Ohio is triggered by $100,000 in sales or 200 transactions per year with Ohio buyers. As a result, most purchases from major national retailers — Amazon, Target, Walmart's marketplace, and similar platforms — include Ohio sales tax at checkout. The use tax obligation primarily remains relevant for purchases from small, niche, or international online sellers who are below the economic nexus threshold and do not register to collect.

Businesses registered for Ohio sales and use tax are required to track and self-report use tax obligations on a regular basis, typically monthly or quarterly depending on their reporting schedule. Consumers — individuals rather than businesses — can self-report use tax on Ohio's individual income tax return (IT 1040) using the use tax line. The Ohio Department of Taxation has periodically conducted audits of businesses and has the authority to assess use tax plus interest and penalties for unreported obligations. Keeping records of out-of-state purchases and whether Ohio tax was collected is good practice for businesses with significant procurement activity.

Motor vehicle sales in Ohio are subject to the state sales tax rate of 5.75% plus the county surtax applicable to the buyer's county of residence, for a combined rate that mirrors the ordinary consumer sales tax in that county. Ohio calculates the tax on the full purchase price of the vehicle, including any accessories or add-ons that are part of the selling price, but allows a trade-in deduction: the value of a trade-in vehicle reduces the taxable purchase price, so you only pay sales tax on the net amount after the trade-in. This trade-in deduction provides a meaningful tax saving compared to states that tax the full vehicle price regardless of trade-in.

For example, if you purchase a vehicle for $35,000 and trade in your current vehicle for $10,000, Ohio taxes the $25,000 net difference. In Franklin County with a 7.5% combined rate, the tax on $25,000 is $1,875, rather than the $2,625 that would apply on the full $35,000 purchase price. This $750 saving from the trade-in deduction is one reason Ohio consumers often opt to trade in vehicles at the dealership rather than selling privately — the tax benefit of the deduction can offset or exceed any additional proceeds from a private sale. Vehicle sales tax is collected by the dealership at the time of purchase and remitted to the county treasurer.

Out-of-state vehicle purchases brought into Ohio for registration are subject to Ohio's use tax at the combined rate for the buyer's county. If sales tax was already paid in another state, Ohio provides a credit for the tax paid elsewhere, so the buyer owes the difference between the Ohio rate and the other state's rate (or nothing if the other state's rate is equal to or higher than Ohio's). Title transfers and registration for newly purchased vehicles must be completed within 30 days of purchase, and the use tax is assessed and collected by the county title office as part of the titling process. Failure to title within the required timeframe can result in additional fees and penalties.
