Oklahoma Sales Tax Calculator

Imagine you own a retail shop in Tulsa, Oklahoma, where the combined sales tax rate (state + local) is 8.517%. A customer buys an item priced at $150, and you need to calculate the sales tax and the total amount the customer will pay.

Step 1: Determine the Total Sales Tax Rate

Oklahoma’s total sales tax rate includes the state tax rate (4.5%) plus the local tax rate for Tulsa (4.017%):

Total Sales Tax Rate = State Rate + Local Rate

4.5% + 4.017% = 8.517% (or 0.08517 in decimal form)

Step 2: Calculate the Sales Tax

Use the formula for calculating sales tax:

Sales Tax = Item Price × Total Sales Tax Rate

Plug in the values:

Sales Tax = 150 × 0.08517 = 12.78

The sales tax on the $150 item is $12.78.

Step 3: Calculate the Total Price

Add the sales tax to the original price of the item to determine the total amount the customer will pay:

Total Price = Item Price + Sales Tax

Total Price = 150 + 12.78 = 162.78

Final Answer:

The total price of the item, including sales tax, is $162.78.

Additional Considerations:

Local Tax Variations: Sales tax rates differ by city and county. Use the Oklahoma Tax Commission’s Sales Tax Rate Locator to determine the correct rate for each transaction.
Exemptions: Certain items, such as prescription drugs and groceries, may be exempt from sales tax in Oklahoma. Verify whether your item qualifies for an exemption.
Remote Sales: If you sell online to Oklahoma customers and exceed the economic nexus threshold of $100,000 in annual sales, you must collect and remit sales tax based on the customer’s location.

By following this method, businesses in Oklahoma can accurately calculate sales tax, ensuring compliance with state and local regulations.
