How Oklahoma withholding works in 2026
Oklahoma uses its own OK-W-4 alongside your federal W-4. Your employer subtracts $1,000 for each allowance you claim (spread over your pay periods, for example $38.46 per allowance on a biweekly paycheck), then looks up the tax in the Oklahoma Tax Commission's 2026 tables (Packet OW-2), which tax the rest at 2.5%, 3.5% and 4.5%. Employers round the result to the nearest dollar.
The standard deduction is already built into those tables ($6,350 for single filers and $12,700 for married filing jointly on the return), so a single filer pays no Oklahoma withholding on roughly the first $10,100 of annual pay after allowances, and a married filer on roughly the first $20,200. For example, a single filer earning $60,000 with one allowance has about $2,150 withheld for the year, or about $83 per biweekly paycheck.
Filling out the OK-W-4
Line 1: enter 1 for yourself. Line 2: if your spouse works, enter 0; if not, enter 1 for your spouse. Line 3: the number of dependents you will claim, not counting yourself, your spouse, or dependents your spouse already claimed. Line 4: optional additional allowances if you itemize or have other deductions or credits that lower your Oklahoma tax. Line 5 is the total, and Line 6 is any extra amount you want withheld each pay period.
The form's filing status choices are Single, Married, and Married but withhold at higher Single rate. If you and your spouse both work, the higher Single rate option is the safer choice, because Oklahoma taxes married couples on their combined income and one paycheck's Married table doesn't know about the other.
Claiming exempt and other special cases
Write Exempt on Line 7 if you had a right to a refund of all the Oklahoma tax withheld last year because you had no tax liability, and you expect the same this year. The form says that if your income will be less than your personal exemption plus the standard deduction, you should mark Exempt.
Lines 8 and 9 cover military situations: Line 8 for the spouse of a servicemember who qualifies under the Military Spouses Residency Relief Act (with Form OW-9-MSE), and Line 9 for military pay that qualifies for Oklahoma's military income deduction. Oklahoma has no local income taxes, so there is nothing to add for your city or county.
Oklahoma W-4 FAQ
What is Oklahoma's income tax rate in 2026?+
Oklahoma's withholding tables for 2026 use rates of 2.5%, 3.5% and 4.5%. The top rate is 4.5%, down from 4.75% in 2025. Oklahoma has no local income taxes.
What is the OK-W-4 form?+
The OK-W-4 is the Oklahoma Tax Commission's Employee's State Withholding Allowance Certificate. You give it to your employer, not the state. It sets your filing status, your allowances for yourself, your spouse and dependents, any extra withholding, and whether you are exempt.
How much is an Oklahoma withholding allowance worth?+
Each allowance is the $1,000 personal exemption divided by your pay periods: $19.23 weekly, $38.46 biweekly, $41.67 semi-monthly or $83.33 monthly. Each one reduces the pay your employer taxes.
Should I claim an allowance for my spouse?+
Only if your spouse does not work. On Line 2, enter 0 if your spouse works and 1 if they don't. If both of you work, consider the Married, but withhold at higher Single rate option so the two paychecks together cover your tax.
How do I claim exempt on the OK-W-4?+
Write Exempt on Line 7 if you had a right to a refund of all Oklahoma tax withheld last year because you had no tax liability, and you expect the same this year. You will owe tax and possibly penalties at filing if you are not entitled to it.
Does Oklahoma use the same standard deduction as the federal W-4?+
No. Oklahoma's standard deduction is $6,350 for single filers and $12,700 for married filing jointly, and it is already built into the state's withholding tables. The federal W-4 standard deduction does not apply to your state withholding.
