How Oklahoma State Income Tax Works

Oklahoma restructured its individual income tax under HB 2764, effective for the 2026 tax year. The law reduced the top rate from 4.75% to 4.5% and consolidated six tax brackets into four simplified brackets. Oklahoma uses a graduated rate system with rates ranging from 0% to 4.5%.

For single filers and married filing separately, the brackets are: 0% on the first $3,750, 2.5% on income between $3,750 and $4,900, 3.5% on income between $4,900 and $7,200, and 4.5% on income over $7,200. For married filing jointly and head of household filers, the bracket thresholds are doubled.

Oklahoma offers a standard deduction of $6,350 for single filers, $12,700 for married filing jointly, and $9,350 for head of household. A personal exemption of $1,000 ($2,000 for married couples) plus $1,000 per dependent is also available.

Key features of Oklahoma state income tax:

• Graduated rates: 0%, 2.5%, 3.5%, and 4.5% (top rate reduced from 4.75%)
• State standard deduction and personal exemption available
• Automatic rate reduction triggers tied to state revenue performance
• Social Security benefits are exempt from Oklahoma tax

Pre-Tax Deductions
