The sales tax rate for ZIP code 45011 is 6.50%. That covers Hamilton, Ohio, and the surrounding Butler County communities inside the ZIP, and the rate is the same at every register in the area because the whole ZIP sits in one county.
How the 6.50% Breaks Down
Two separate levies combine to make the total. Ohio Revised Code Section 5739.02 sets the statewide sales tax at 5.75% on retail sales of tangible personal property and certain services.1Ohio Legislative Service Commission. Ohio Code 5739.02 – Levy of Sales Tax – Purpose – Rate – Exemptions Every county in Ohio collects that baseline.
Butler County adds 0.75% on top under Ohio Revised Code Section 5739.021, which lets counties impose up to 1.5% in additional sales tax for general revenue and public services.2Ohio Legislative Service Commission. Ohio Code 5739.021 – Additional Sales Tax Levied by County The Ohio Department of Taxation lists Butler County’s current combined state-and-county rate at 6.50%.3Ohio Department of Taxation.

Which Rate Applies to Your Purchase
ZIP codes exist for mail delivery, not tax collection, but 45011 falls entirely inside Butler County, so the 6.50% rate applies throughout. The harder question is which location’s rate controls a given transaction, and Ohio answers it differently depending on where the seller is based.
When an Ohio retailer sells to an Ohio customer, the sale is sourced to the place where the vendor receives the order, not where the buyer picks the goods up or where they ship from.4Ohio Department of Taxation. Sales and Use Tax – Sourcing Walk into a store in Hamilton, and the store’s Butler County location triggers the 6.50% rate. Phone or online an Ohio vendor, and whichever Ohio location receives your order sets the county rate.
Out-of-state sellers follow a different rule. They source the sale to wherever the customer receives the goods.4Ohio Department of Taxation. Sales and Use Tax – Sourcing Order something from a retailer in another state and have it shipped to a 45011 address, and the Butler County 6.50% rate applies because that’s where delivery happens.
Calculating the Tax
Multiply the pre-tax price by 0.065. A $100 purchase carries $6.50 in tax, for a total of $106.50. A $47.99 item produces $3.11946 in tax before rounding.
Ohio requires the calculation to be carried out to three decimal places. If the third decimal is 5 or higher, the tax rounds up to the next cent; 4 or lower rounds down. In the $47.99 example, the third decimal is 9, so the tax rounds up to $3.12 and the total comes to $51.11. Vendors can apply this calculation either item-by-item or to the invoice total. Both methods are acceptable.5Ohio Department of Taxation. Sales and Use Tax Calculation and Rounding Change
What’s Taxed and What Isn’t
Ohio taxes most physical goods and a specific list of services. The exemptions that matter most for everyday shoppers involve groceries, medicine, and professional services.
Groceries and Food
Food for human consumption bought at a grocery store and taken off the premises is exempt.1Ohio Legislative Service Commission. Ohio Code 5739.02 – Levy of Sales Tax – Purpose – Rate – Exemptions Bread, produce, dairy, meat, canned goods: none of it carries the 6.50% charge when you buy it to eat at home. Prepared meals from restaurants are fully taxable. The line sometimes trips people up. A rotisserie chicken from the grocery deli that you take home is generally exempt. A meal served at a restaurant counter is not.
Prescriptions and Medical Equipment
Prescription medications dispensed for human use are exempt, along with insulin, diabetic testing supplies, and syringes used for insulin injections.1Ohio Legislative Service Commission. Ohio Code 5739.02 – Levy of Sales Tax – Purpose – Rate – Exemptions Prosthetic devices, durable medical equipment for home use, and mobility-enhancing equipment also qualify for exemption when sold with a prescription.6Ohio Department of Taxation. Sales and Use Tax – Drugs, Durable Medical Equipment, Mobility Enhancing Equipment Over-the-counter medications without a prescription are generally taxable.
Services
Ohio doesn’t tax most services, but it specifically taxes a handful. Laundry, dry cleaning, and landscaping are all subject to sales tax.7Ohio Legislative Service Commission. Ohio Code 5739.01 – Sales Tax Definitions Professional services like legal advice, accounting, and medical care are not taxable. The split doesn’t follow an obvious pattern. It’s a matter of what the legislature specifically included.
Digital Goods and Streaming
Ohio taxes prewritten software, whether purchased online or on physical media, along with downloads like e-books and music and streaming services such as Netflix and Hulu.8Ohio Department of Taxation. Sales and Use Taxability If your streaming billing address is in 45011, the 6.50% rate applies to your monthly charge.
Shipping and Delivery
When a seller charges you for shipping or delivery on a taxable item, that charge is part of the taxable price. Ohio Administrative Code Rule 5703-9-52 defines delivery charges, including transportation, postage, handling, crating, and packing, as part of the sale price. If an order contains both taxable and exempt items, the seller should allocate the shipping charge proportionally; if the seller doesn’t allocate it and any part of the shipment is taxable, tax applies to the entire delivery charge.9Ohio Legislative Service Commission. Rule 5703-9-52 – Delivery Charges One exception: if you hire a separate delivery company yourself instead of paying the seller’s shipping fee, that independent charge is not subject to sales tax.
