Income tax in Oklahoma

For 2025 Oklahoma kept its six-bracket schedule from 0.25% to 4.75%, but the bands are so narrow that most earners hit the top rate after just $7,200 of taxable income (single). A May 2025 law cuts the top rate to 4.5% and consolidates the brackets starting in tax year 2026, with revenue triggers that could phase rates down further. Capital gains are taxed as ordinary income, though gains on certain Oklahoma-based property can qualify for a deduction.
