The Oklahoma Sales Tax Calculator helps you quickly determine the sales tax on a purchase in any area of Oklahoma. You can calculate sales tax by adding it to a pre-tax amount or removing it from a total amount.
When adding sales tax:
- Tax Amount = Pre-Tax Amount × Tax Rate
- Total Amount = Pre-Tax Amount + Tax Amount
When removing sales tax:
- Pre-Tax Amount = Total Amount ÷ (1 + Tax Rate)
- Tax Amount = Total Amount – Pre-Tax Amount
Oklahoma has a state sales tax rate of 4.5%, with local jurisdictions adding additional sales tax. The combined rates vary by location from 4.5% to 11.5%. This calculator provides accurate calculations for all tax rates in the state.
Adding Sales Tax Example
Let’s say you want to calculate sales tax on a $1,500 product in Oklahoma City with the standard tax rate of 8.5%:
Pre-Tax Amount = $1,500
Tax Rate = 8.5% or 0.085
Calculate the tax amount:
Tax Amount = $1,500 × 0.085 = $127.50
Calculate the total amount:
Total Amount = $1,500 + $127.50 = $1,627.50
Removing Sales Tax Example
Now, let’s say you have a total amount of $1,627.50 and want to calculate the pre-tax amount and tax in Oklahoma City:
Total Amount = $1,627.50
Tax Rate = 8.5% or 0.085
Calculate the pre-tax amount:
Pre-Tax Amount = $1,627.50 ÷ (1 + 0.085) = $1,627.50 ÷ 1.085 = $1,500.00
Calculate the tax amount:
Tax Amount = $1,627.50 – $1,500.00 = $127.50
State Rate Only Example
Using only the state rate of 4.5%, let’s calculate tax on a $1,500 product:
Pre-Tax Amount = $1,500
Tax Rate = 4.5% or 0.045
Calculate the tax amount:
Tax Amount = $1,500 × 0.045 = $67.50
Calculate the total amount:
Total Amount = $1,500 + $67.50 = $1,567.50

Understanding Oklahoma Sales Tax
What is Oklahoma Sales Tax?
Oklahoma sales tax is a consumption tax imposed by the state and local jurisdictions on the sale of goods and certain services. The state rate is 4.5%, with local jurisdictions adding additional tax. Sales tax is collected by retailers at the point of sale and remitted to the Oklahoma Tax Commission.
Local Sales Taxes
In addition to the state sales tax, counties and cities in Oklahoma can impose local sales taxes. These local rates vary by jurisdiction and are added to the state rate. Urban areas like Oklahoma City and Tulsa typically have combined rates of 8.5%, while most other areas have rates of 9% or higher.
Tax Collection
Sales tax in Oklahoma is collected by sellers at the point of sale and remitted to the Oklahoma Tax Commission. Sellers must register with the state and obtain a Sales Tax Permit before collecting tax. Returns are typically filed monthly, quarterly, or annually depending on the volume of sales.
Use Tax
Oklahoma use tax applies when sales tax has not been paid on taxable items purchased outside the state for use in Oklahoma. The use tax rate is the same as the sales tax rate that would have applied if the purchase was made within the state. This ensures that out-of-state purchases don’t have an unfair advantage over in-state purchases.
Business Registration
Businesses selling taxable goods or services in Oklahoma must register for a Sales Tax Permit with the Oklahoma Tax Commission. Registration can be done online through the department’s website. Once registered, businesses must collect sales tax on all taxable transactions and file regular returns.
Filing Requirements
Sales tax returns in Oklahoma are typically filed monthly, but businesses with lower sales volume may file quarterly or annually. Filing is done through the Oklahoma Tax Commission’s online system, and payments are due by the 20th of the month following the reporting period.
Oklahoma Sales Tax for Businesses
Nexus Requirements
Businesses must collect Oklahoma sales tax if they have nexus in the state. Nexus can be established through physical presence, economic activity, or other connections. Oklahoma follows economic nexus rules, requiring out-of-state sellers to collect tax if they have more than $100,000 in sales into the state in the previous calendar year.
Marketplace Facilitators
Marketplace facilitators like Amazon and eBay are required to collect and remit sales tax on behalf of third-party sellers selling into Oklahoma. This applies to marketplace facilitators with more than $100,000 in sales into the state. The facilitator is responsible for collecting and remitting the tax on all sales made through their platform.
Exemption Certificates
Businesses purchasing items for resale can provide exemption certificates to sellers to avoid paying sales tax. Oklahoma has specific forms that must be completed and provided to the seller at the time of purchase. The certificate must be updated periodically and must include specific information about the purchaser and the type of exemption being claimed.
Shipping and Handling
In Oklahoma, shipping and handling charges are generally taxable if they are part of the sale of tangible personal property. If the charges are separately stated and related to transportation services, they may be exempt. The taxability depends on whether the charges are considered part of the sale or a separate service.
Penalties and Interest
Oklahoma imposes penalties for late filing and late payment of sales tax. The penalty is 5% of the tax due per month, up to a maximum of 25%, plus interest at the rate determined by the Oklahoma Tax Commission. Failure to file or pay can result in additional penalties and legal action, including revocation of business licenses.
Tax Calculation Services
Given the complexity of Oklahoma’s sales tax system with different rates in various jurisdictions, many businesses use automated tax calculation services to ensure accurate collection and remittance of sales tax. These services help businesses stay compliant with changing tax laws and rates.
