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.
