Oklahoma state income tax

Can You Write Off Oklahoma state income tax?

Short answer: For 2026 Oklahoma taxes the first $3,750 (single) / $7,500 (MFJ/HoH) at 0%, then 2.5% and 3.5%, with a 4.5% top rate above $7,200 (single) / $14,400 (MFJ/HoH), down from 4.75% (HB 2764).

Oklahoma's standard deduction is frozen at 2017 levels ($6,350 single, $9,350 HoH, $12,700 MFJ) rather than following the federal amount; future 0.25-point rate cuts are triggered by revenue growth. State and local income, sales, and property taxes share one SALT cap ($40,400 for 2026, reduced above about $505,000 of income) and only help if you itemize.

Records to keep: Keep your state return, W-2s and 1099s (1099-R, SSA-1099), and any state credit worksheets. Check your state revenue department's current-year instructions before you file.
