Oklahoma (OK) Paycheck Calculator 2026

Form OK-W-4 and Oklahoma withholding allowances

Oklahoma employers calculate state withholding from the allowances you claim on Form OK-W-4. Each allowance is worth the Oklahoma personal exemption of $1,000 a year — $83.33 per monthly paycheck or $41.67 per semimonthly paycheck — and is subtracted from your wages before the withholding rates apply.

The OK-W-4 also has a box to withhold at the higher single rate if you are married. Two-earner couples should use it, because otherwise each employer withholds as though the household had only one income.

New Oklahoma rates in 2026

Oklahoma collapsed its six brackets into three rates for 2026: 2.5%, 3.5%, 4.5%, with the first $3,750 of taxable income ($7,500 for joint filers) taxed at 0%. The top rate fell from 4.75% to 4.5%, and it applies to taxable income over just $7,200 (single), so almost every full-time worker’s extra dollar is taxed at 4.5%.

Oklahoma paycheck examples

Bi-weekly checks for 2026, using the $6,350 single standard deduction and $1,000 exemptions. Oklahoma has no local income tax and no employee-paid disability or family leave program.

• At $55,000, Oklahoma takes about $74 per check, an effective state rate of 3.51%.
• Each child adds a $1,000 exemption, which saves at most $45 a year in Oklahoma tax.

Minimum wage and pay periods

Oklahoma adopts the federal minimum wage by reference: $7.25 an hour for employers with 10 or more full-time employees or more than $100,000 in annual gross sales. Other employers not covered by federal law may pay $2.00. Oklahoma requires at least semimonthly paydays for most employees, so check whether your employer pays 24 or 26 times a year.

Common mistakes on Oklahoma paychecks

The most frequent problems are an outdated OK-W-4 that claims allowances for children who have grown up, married couples who both claim the married rate, and workers with a second job who never adjust either withholding certificate. If you received a large Oklahoma balance due last spring, file a new OK-W-4 with fewer allowances or an extra dollar amount per pay period.
