Budget & Taxes

HB 1539 lowers Oklahoma's individual income tax rates for the 2024 tax year. It reduces the top tax rate from 5.50% to 4.75% for most filers, with new brackets starting at 0.25% on the first $1,000 of income (e.g., 0.75% on the next $1,500 for single filers). The bill affects all Oklahoma residents and nonresidents who file individual income tax returns, applying to taxable income earned in 2024. The change eliminates the previous tiered top rate structure and requires no deduction for federal income taxes paid.

SB 291 creates a refundable income tax credit for Oklahoma residents based on revenue growth from oil, natural gas, and corporate income taxes. If the State Board of Equalization certifies that revenue growth exceeds 10% in a year, the Oklahoma Tax Commission calculates a credit amount using a formula based on the number of individual and married-filing-jointly tax returns from the prior year. The credit is doubled for married couples filing jointly, and the Commission must publish the calculated amount within 45 days of certification. The credit applies to tax years starting in 2026, with a November 1, 2025 effective date.
