Oklahoma sales tax by address

For information only, not tax advice

The rate at one address can differ from the rate for its city. Here is how to find the exact figure, and what decides which rate applies.

Use the official rate locator

The Oklahoma Tax Commission (OTC) publishes the Sales and Use Tax Rate Locator. It looks up rates by address, municipality, county, ZIP code, ZIP+4 and default ZIP rates. Vendors can also download the address database from the same tool. It is the right place to settle the rate for one address.

The tool is hosted for OTC by the University of Oklahoma and is linked from the OTC Sales and Use Tax page. MuniRevenue is not affiliated with either.

Why one city can have more than one rate

The combined rate on the OTC chart is the 4.5% state rate, plus the city rate, plus the county rate, for the place where the sale is sourced. Two addresses with the same city name can land in different counties. Other local levies may apply at some addresses, so use the locator and confirm with the Oklahoma Tax Commission.

The OTC help center explains that local rates are tied to ZIP+4, and that where city and county boundaries overlap in a ZIP+4 area, the lowest rate in the area applies. Questions about a ZIP+4 go to the U.S. Postal Service address tool, as OTC notes on its help center.

Which address sets the rate

  • Sold at the seller's place of business: the rate at that location applies.
  • Delivered somewhere else: the rate where the buyer receives the product applies, and shipped goods are taxed at the rate where delivery occurs.
  • Remote sellers: they collect state and local tax on sales delivered to Oklahoma addresses.
  • Bought out of state and brought home: Oklahoma use tax may be owed when no Oklahoma tax was paid.

City boundaries change

OTC runs a Municipal Boundary Changes viewer. You can search by city, ordinance number or date. OTC marks it as informational only and possibly inaccurate, and refers readers to the county clerk for boundary questions. If an address sits near a city edge, check the locator and confirm with the Oklahoma Tax Commission.

Cities in more than one county

Frequently asked questions

How do I find the exact sales tax rate for an Oklahoma address?

Use the Oklahoma Tax Commission Sales and Use Tax Rate Locator. It searches by address, municipality, county, ZIP code and ZIP+4. The rates on MuniRevenue are jurisdiction-wide, so use the locator when the address matters.

Which rate applies when a city and county overlap in a ZIP+4 area?

The Oklahoma Tax Commission says local rates are tied to ZIP+4, and where city and county boundaries overlap in a ZIP+4 area, the lowest rate in the area applies. Confirm a specific case with the Oklahoma Tax Commission.

Does an online purchase use my address or the seller's address?

For goods shipped to you, the rate where you receive them applies. For a sale made at the seller's place of business, the seller's location sets the rate. Remote sellers collect state and local tax on sales delivered to Oklahoma addresses.
