How is Oklahoma income tax withheld from a paycheck?
Employers withhold Oklahoma income tax from each paycheck, using the Form OK-W-4 each employee fills in. On a $75,000 salary paid every two weeks, that is $109.00 a paycheck. Oklahoma employers withhold about $5 more a year than the tax owed on $75,000, so a typical worker gets it back at filing.
Employer withholding tables can differ from the yearly tax owed; the return settles the difference.
How this is calculated
- Percentage tables from Packet OW-2 (2026): wages minus $1,000 a year per allowance, then the single or married table, rounded to the dollar. The calculator assumes Form OK-W-4 with married status only for married filers (heads of household withhold as single) and allowances for you, a spouse with no wages and each dependent.
