Oklahoma tax rules to know
Key points from our 2026 Oklahoma data, compiled from the official sources listed at the end of this page:
- HB 2764 (signed May 2025) takes effect for tax year 2026: the six old brackets are collapsed into a 0% band plus three rates (2.5%, 3.5%, 4.5%) and the top rate falls from 4.75% to 4.5%. Single and married-filing-separately filers: 0% on the first $3,750, 2.5% to $4,900, 3.5% to $7,200, 4.5% above. MFJ, qualifying surviving spouse and head of household: 0% on the first $7,500, 2.5% to $9,800, 3.5% to $14,400, 4.5% above. Brackets are not indexed.
- Further 0.25-point cuts occur only if the State Board of Equalization certifies revenue growth triggers (earliest possible effective date Jan 1, 2028). HB 4072 (signed April 23, 2026) created a taxpayer endowment fund aimed at eventually eliminating the tax but did not change 2026 rates.
- Standard deduction (not indexed): $6,350 single/MFS, $12,700 MFJ/qualifying surviving spouse, $9,350 HOH. Personal exemption: $1,000 each for taxpayer, spouse and each dependent, plus an additional $1,000 for taxpayers 65+ with low AGI (e.g., $15,000 single, $25,000 joint) and for blindness.
- If you itemize, Oklahoma itemized deductions (other than medical and charitable contributions) are capped at $17,000.
Local income tax: none. Cities and counties in Oklahoma do not levy their own income tax in our 2026 data.
