Quick answer
Oklahoma paycheck basics
Oklahoma cut and simplified its income tax for 2026. House Bill 2764 lowered the top rate to 4.5% and consolidated the schedule into three taxed brackets: after the first $3,750 of taxable income, which is taxed at 0%, single filers pay 2.5% up to $4,900, 3.5% up to $7,200 and 4.5% above. Married couples filing jointly, heads of household and surviving spouses use brackets twice as wide. Because the top rate starts so low, almost every full-time worker's paycheck is withheld mostly at 4.5%.
Employers withhold Oklahoma tax from Form OK-W-4 using the Oklahoma Tax Commission's 2026 withholding tables, Packet OW-2. This calculator applies the OW-2 percentage formula, including its rule of rounding to the nearest whole dollar, and combines it with federal income tax, Social Security and Medicare to show your take-home pay. Oklahoma has no local income tax and no employee-paid state disability or paid leave deduction.
How Oklahoma taxes your paycheck
Oklahoma withholding uses the percentage formula in Packet OW-2. Your employer first multiplies your withholding allowance amount by the allowances on your OK-W-4: one allowance is the $1,000 personal exemption divided by your pay periods, $38.46 on a biweekly paycheck. That comes off your gross pay, and the rest runs through the table for your pay period, Single or Married. Each table has a 0% band that reflects the standard deduction and the 0% bracket ($388 biweekly for single, $777 for married), then withholds 2.5%, 3.5% and 4.5% on the amounts above. The result is rounded to the nearest whole dollar. In OW-2's example, a married employee paid $1,825 semi-monthly with two allowances has $36.67 calculated and $37 withheld. Married employees who check "Married, but withhold at higher Single rate" use the single table. A bonus paid separately may be withheld at 4.5%, the highest rate for the year. Traditional 401(k) deferrals and pretax health benefits reduce Oklahoma wages as they do federal wages.

Frequently asked questions
How is federal income tax withheld from my paycheck calculated?+
Employers use the IRS Publication 15-T percentage method with the elections on your Form W-4: filing status, whether Step 2 is checked, Step 3 credits, and any Step 4 adjustments. That produces an amount to withhold each pay period before Social Security, Medicare, and any state or local tax are applied.
What is FICA and why is it withheld on every paycheck?+
FICA is Social Security tax (6.2% of wages up to the annual Social Security wage base) plus Medicare tax (1.45% of all wages, with an extra 0.9% on wages above $200,000 in a year). Both are withheld on every US paycheck regardless of which state you work in, because they fund federal programs rather than a state one.
Is the result on this calculator the same as my actual paycheck?+
It is an estimate for planning, not a substitute for your pay stub. Your actual withholding depends on the exact elections on file with your employer, your specific pay dates, and any mid-year changes to your deductions — the calculator applies the published federal and state formulas to the numbers you enter.
What are the Oklahoma income tax rates for 2026?+
For single and married-filing-separately filers: 0% on the first $3,750 of taxable income, 2.5% up to $4,900, 3.5% up to $7,200 and 4.5% above. Married filing jointly, head of household and surviving spouse filers pay the same rates on brackets of $7,500, $9,800 and $14,400.
What changed in Oklahoma's income tax for 2026?+
HB 2764, effective for tax year 2026, cut the top rate to 4.5% and collapsed the brackets, so the first $3,750 of taxable income ($7,500 joint) is taxed at 0% and three rates apply above it. The same law allows further 0.25-point cuts in later years when revenue conditions are met.
How much Oklahoma tax is withheld on a $60,000 salary?+
For a single employee paid biweekly with one allowance, $2,307.69 less the $38.46 allowance is $2,269.23. The biweekly single table withholds $4.20 plus 4.5% of the amount over $521, $82.87, which rounds to $83 per paycheck.
How much is an Oklahoma withholding allowance worth?+
$1,000 a year, the Oklahoma personal exemption, divided by your pay periods: $19.23 weekly, $38.46 biweekly, $41.67 semi-monthly and $83.33 monthly.
How are bonuses taxed in Oklahoma?+
A bonus combined with regular pay is withheld as one payment. If it is paid separately or listed separately, your employer can withhold at the highest Oklahoma rate, 4.5% for 2026, or add it to your last regular pay and withhold the difference.
Should married couples who both work use the single rate?+
Oklahoma taxes married couples on their combined income, and OW-2 notes that many two-income couples are underwithheld. Checking "Married, but withhold at higher Single rate" on the OK-W-4 makes each employer use the single table.
Does Oklahoma tax 401(k) contributions?+
No. Traditional 401(k) deferrals and pretax health premiums reduce Oklahoma wages the same way they reduce federal wages.
Does Oklahoma have local income taxes?+
No. Oklahoma cities and counties do not tax wages.
What is the minimum wage in Oklahoma?+
$7.25 an hour for employers with ten or more full-time employees or more than $100,000 in annual gross sales, matching the federal minimum.
