How to calculate Oklahoma sales tax
Adding tax to a price
Multiply the pre-tax amount by 1.045.
$250.00 × 1.045 = $261.25 total ($11.25 tax)
Removing tax from a total (reverse)
Divide the tax-inclusive total by 1.045 to find the pre-tax amount.
$500.00 ÷ 1.045 = $478.47 pre-tax
These examples use the 4.5% state rate only. Where local taxes apply, add the combined local rate for the point of sale.
