Dublin, Ohio Sales Tax Rate: Breakdown, Exemptions, and Use Tax

The Dublin, Ohio sales tax rate is either 7% or 8%, depending on where in the city the sale takes place. Dublin’s limits cross Franklin, Delaware, and Union counties, and a Central Ohio Transit Authority (COTA) levy that took effect April 1, 2025 pushed the rate to 8% in some parts of the city while leaving others at 7%.1Ohio Department of Taxation. Sales and Use Tax Rate Change Effective April 1, 2025

The split works like this:

  • Franklin County portion of Dublin: 8%. The entire county sits in the COTA district.
  • Delaware and Union County portions inside the COTA district: 8%.
  • Delaware and Union County portions outside the COTA district: 7%.

The dollar difference adds up fast. A $1,000 purchase taxed at 8% costs $80 in sales tax; the same purchase at 7% costs $70. Whether a specific Dublin address falls inside or outside the COTA district isn’t always obvious from the street name.

How the Rate Is Built

Every Dublin sales tax bill starts with Ohio’s statewide base rate of 5.75% under Ohio Revised Code Section 5739.02.2Ohio Legislative Service Commission. Ohio Revised Code 5739.02 – Levy of Sales Tax – Purpose – Rate – Exemptions County and transit levies stack on top:

  • Franklin County: 5.75% state + 1.75% county + 0.5% COTA = 8%
  • Delaware or Union County, inside COTA: 5.75% state + 1.25% county + 1.0% COTA = 8%
  • Delaware or Union County, outside COTA: 5.75% state + 1.25% county = 7%

Before April 2025, the Franklin County total was 7.5%.3Ohio Department of Taxation. Sales and Use Tax Rate Change The COTA increase that bumped it to 8% is permanent.

In-Store Versus Online: Which Rate You Pay

Ohio sources sales to a specific location, and that location decides the rate. For in-state sellers, the sale is sourced to where the seller receives the order. For purchases from out-of-state sellers, the sale is sourced to where the buyer receives the goods.5Ohio Department of Taxation. ST 2009-03 – Sales and Use Tax Sourcing

So if you walk into a store on the Franklin County side of Dublin, you pay 8% because the order is received there. If an out-of-state online retailer ships to your home in a non-COTA part of the Delaware County side of Dublin, 7% is the correct rate because that’s where delivery happens. Taxable services follow the same logic and are sourced to where the customer first uses the service.

What’s Taxed

Most physical goods are taxable in Dublin, whether you buy them in a store or have them shipped: electronics, furniture, clothing, appliances, and vehicles all qualify as tangible personal property.6Ohio Department of Taxation. Sales and Use Taxability

Services are different. Ohio taxes only services specifically named in statute, so most professional services (legal, accounting, medical, consulting, advertising) carry no sales tax.7Ohio Legislative Service Commission. Ohio Revised Code 5739.01 – Definitions Services that are taxed include repair and installation of personal property, landscaping and lawn care, janitorial and building maintenance, vehicle washing and detailing, laundry and dry cleaning, pest control, private investigation and security, physical fitness facilities, and personal care services such as skin care, manicures, tattoos, tanning, and massage. Haircuts and hair styling are not taxed.

What’s Exempt

The biggest exemption for most households covers groceries. Food for human consumption bought for off-premises eating is not taxed, so standard grocery store purchases carry no sales tax.2Ohio Legislative Service Commission. Ohio Revised Code 5739.02 – Levy of Sales Tax – Purpose – Rate – Exemptions Prepared food eaten on-site at a restaurant or deli counter is taxable.8Ohio Department of Taxation. Food Service Industry

Prescription drugs dispensed for human use are exempt, along with insulin, diabetic testing supplies, and hypodermic needles used for insulin injections. Medical oxygen and hospital beds purchased by medical facilities qualify as well. Over-the-counter medications are generally taxable.

The Annual Sales Tax Holiday

Ohio runs a sales tax holiday each summer that temporarily removes both state and local tax from qualifying back-to-school items. In 2026, the holiday runs from 12:00 a.m. Friday, August 7 through 11:59 p.m. Sunday, August 9.9Ohio Department of Taxation. Ohio Sales Tax Holiday Exempt items are:

  • Clothing priced at $75 or less per item
  • School supplies priced at $20 or less per item
  • School instructional materials priced at $20 or less per item

Anything priced above those caps stays fully taxable during the holiday. Ohio is not offering the expanded holiday on items up to $500 in 2026. At the 8% Franklin County rate, $300 in qualifying purchases saves $24.

Use Tax on Untaxed Purchases

If you buy something and no Ohio sales tax is collected, you still owe use tax at your local sales tax rate when you bring the item into Ohio or use it here.10Ohio Department of Taxation. Sales and Use Tax The classic trigger is a purchase from an out-of-state seller that doesn’t collect Ohio tax. Individuals can report small amounts of use tax on their Ohio income tax return. The rate is the same 7% or 8% that would have applied if the seller had collected.

A Note for Dublin Businesses

A single storefront collects a single rate tied to its location. A Dublin business that delivers across the city, though, may be sourcing orders to all three counties and both the COTA and non-COTA zones, which means collecting 7% on some orders and 8% on others. Point-of-sale systems that weren’t updated after April 1, 2025 are likely under-collecting on the Franklin County side and leaving the business liable for the difference.
