Enter gross pay for one pay period, federal W-4 adjustments, and the state details shown above. Federal withholding follows Publication 15-T. Oklahoma subtracts the OW-2 pay-period value of each OK-W-4 allowance, selects the single or married percentage table for the chosen pay frequency, calculates regular withholding from the published bracket, and rounds that regular amount to the nearest whole dollar before adding the employee’s requested additional withholding.
Example: The official 2026 OW-2 example uses $1,825 of semimonthly wages, married status, and two allowances. After subtracting $83.34, the married semimonthly table produces $37 of Oklahoma withholding after whole-dollar rounding. The calculator does not assume any unentered benefit deduction or invent a tax result.
Weekly, biweekly, semimonthly, and monthly are the supported paycheck frequencies. “Annual salary” is an earnings input and the annual view is a simple period multiplication; neither is an annual payroll-period method. The special Form W-4 adjustment for nonresident aliens is not modeled.
