Withholding Formula (Effective Pay Period 03, 2022)
- Subtract the nontaxable biweekly Thrift Savings Plan (TSP) contribution from the gross biweekly wages.
- Subtract the nontaxable biweekly Federal Health Benefits Plan payment(s) (includes dental and vision insurance program and Flexible Spending Account - health care and dependent care deductions) from the amount computed in step 1.
- Add the taxable biweekly fringe benefits (e.g., taxable life insurance) to the amount computed in step 2 to obtain the adjusted gross biweekly wages.
- Multiply the adjusted gross biweekly wages by the number of pay dates in the tax year to obtain the gross annual wages.
- Determine the exemption allowance by applying the following guideline and subtracting this amount from the results in step 4 to compute the taxable income:
Exemption Allowance = $1,000 x Number of Exemptions
- Apply the taxable income computed in step 5 to the following table(s) to determine the annual Oklahoma tax withholding:
