Ohio Sales Tax Rate and How Local Tax Is Calculated

Ohio sales tax starts with a 5.75 percent state rate, but the amount charged on a taxable purchase can be higher because counties and regional transit authorities can add local tax. The Ohio Department of Taxation says the overall state, local and transit rate cannot exceed 8.75 percent under its current sales and use tax guidance.[1]

The answer to “what is Ohio sales tax” therefore depends on more than the state number. The county, transit area, delivery location, item or service and current rate period can all matter. Ohio provides a rate-finding service called the Finder, which can return information by address, ZIP code or GPS coordinates.[1]

This article explains the state rate, local additions, use tax, address lookup and simple calculation examples. It is general information rather than a filing decision for a particular person or business. Use current Ohio Department of Taxation instructions when a transaction has a special category or a compliance consequence.

Ohio Sales Tax at a Glance

Tax Foundation’s 2026 Ohio data reports a 5.75 percent state rate and a 7.3 percent average combined state and local rate.[3] The 7.3 percent figure is an average, not the rate for every county or transaction.

Ohio rate information changes by effective date. A rate table that was correct in a previous quarter may not be correct for the current invoice. Always check the current table or Finder result before using a rate in a live calculation.

How Ohio State County and Transit Tax Fits Together

State rate

The state portion is 5.75 percent. For a taxable $100 purchase, the state component alone would be $5.75 before local and transit additions.

County additions

Ohio counties can add sales and use tax in increments. The Department publishes county rate tables with codes, rates and effective periods.[2] A purchase in one county can therefore have a different combined rate from the same purchase in another county.

Regional transit additions

Regional transit authorities can also impose sales and use tax in areas defined by the authority. The relevant boundary may not match a simple city name. The Ohio Department explains that some transit areas cover portions of cities or counties, which is one reason an address or more precise ZIP lookup is safer than a broad city assumption.[1]

Use tax

Ohio use tax can apply when sales tax was due but was not collected by the seller. The Department gives online and out-of-state purchases as examples. If a taxable item is bought without the required tax and then brought home or used in Ohio, the buyer may need to review the use-tax treatment.[1]

How to Find an Ohio Rate by Address or ZIP Code

Use the Ohio Department of Taxation’s Finder for a location-specific rate. The Department says the Finder can return a tax rate by address, ZIP code or GPS coordinates.[1]

Follow these steps:

1. Identify the address where the transaction is completed, delivered or used.
2. Open the Ohio Department of Taxation Finder or current rate table.
3. Enter the full address or ZIP code.
4. Review the county and any regional transit area shown.
5. Confirm the effective date before using the rate.
6. Save the result with the invoice or calculation record.

A five-digit ZIP code can cover more than one taxing jurisdiction. A full street address or nine-digit ZIP code can be more precise. The Ohio Department specifically warns that five-digit ZIP searches may return multiple jurisdictions because ZIP boundaries and taxing boundaries do not always match.[1]

For a business with several locations, keep a rate log for each place. Record the address, rate, effective date, source and date checked. This is more reliable than copying one rate into every invoice template.

What Purchases May Be Taxable

The Ohio Department says sales tax applies to retail sales, leases and rentals of tangible personal property, along with selected services.[1] Tangible personal property means a physical item that can be touched, such as clothing, electronics or furniture.

Examples that may require a taxability check include equipment, office furniture, repair services, restaurant transactions, rentals, software-related products and other selected services. An exemption can change the result. A purchase made for resale may receive different treatment from an item taken from inventory for business or personal use.

Keep the invoice, seller information, item description, tax line, exemption document and intended use. If a tax was not charged, do not assume that the transaction is exempt. Check whether a use-tax question exists.

Motor vehicles, watercraft, aircraft, food, lodging, admissions and other special categories can have their own rules. The general rate formula in this article is useful for a simple taxable purchase, but it should not replace Ohio’s category-specific guidance.

How to Calculate Ohio Sales Tax

For a simple taxable purchase, use:

Sales tax = taxable price x combined tax rate

Write the percentage as a decimal before multiplying. A combined rate of 7.25 percent becomes 0.0725.

For a taxable $200 item at a 7.25 percent combined rate:

$200 x 0.0725 = $14.50 tax

The total paid would be:

$200 + $14.50 = $214.50

This example assumes that the full $200 is taxable, the 7.25 percent rate is correct for the location and transaction, and no exemption or special rule applies.

If the total already includes tax and you know the correct rate, divide the total by 1 plus the rate as a decimal. At 7.25 percent, a $214.50 tax-inclusive total gives:

$214.50 / 1.0725 = $200 pre-tax amount

A reverse calculation separates a tax-inclusive total. It does not establish that the item is taxable or prove that a particular county or transit rate applies.

Ohio Sales Tax for Businesses and Online Purchases

A person or business making taxable sales or providing taxable services generally needs to review Ohio’s vendor-license requirements. The Ohio Department says the state requires taxable sellers to obtain a vendor license and provides registration routes through its tax services and county auditor resources.[1]

Online sellers should separate the tax collection question from the rate question. First determine whether the item or service is taxable. Then determine the location and current combined rate. Finally check whether the seller, marketplace or another party already collected the tax.

If an online or out-of-state purchase arrives without the required sales tax, the buyer should review Ohio use-tax information. The Ohio Department describes use tax as applying where sales tax was due but not collected by the seller.[1]

The Department describes its sales tax as a trust tax because retailers collect it on behalf of the state and transfer it in a timely manner. This is an important business recordkeeping point. Collected sales tax is not ordinary business revenue, and a business should keep tax amounts separate in its accounting system.

Rate changes can become effective at the start of a calendar quarter. Ohio’s rate pages list changes by quarter and county. Review the current period before publishing a state-rate table or relying on a saved rate.

Common Questions About Ohio Sales Tax

What is the state sales tax rate in Ohio?

Ohio’s state sales and use tax rate is 5.75 percent according to the Ohio Department of Taxation.[1]

Is Ohio sales tax always 5.75 percent?

No. Counties and regional transit authorities can add local tax, so the combined rate depends on the location and current effective period.

The Ohio Department’s current sales and use tax page states that the overall state, local and transit rate cannot exceed 8.75 percent.[1] Check the current rate source for the address and date.

How do I find Ohio sales tax by ZIP code?

Use the Ohio Department of Taxation Finder. A full address or nine-digit ZIP code may be more precise because a five-digit ZIP can cross taxing jurisdictions.[1]

Does Ohio have a use tax?

Yes. Use tax can apply when sales tax was due but not collected, including some online or out-of-state purchases.

Do Ohio businesses need a vendor license?

The Ohio Department says people or businesses making taxable sales or providing taxable services generally need a vendor license. Review the official registration guidance for the business structure and selling location.[1]

Can I calculate Ohio tax from a receipt total?

Yes, if the correct combined rate is known and the total includes only the tax being separated. Divide the tax-inclusive total by 1 plus the rate as a decimal. Confirm the location and tax category first.

Ohio sales tax is easiest to calculate when the taxable base, location, rate period and transaction type are all confirmed. Start with the 5.75 percent state component, check the county and transit additions, and save the official source with the calculation.

Internal links for publishing

Use the Ohio calculator anchor only if the state-specific tool is eventually built. Until then, link to the main calculator with a descriptive variant anchor rather than publishing a thin doorway page.
