HB 1208 lowers Oklahoma's top individual income tax rates for tax years beginning in 2024 and 2025. It reduces the highest marginal rate from 5.5% to 4.75% for both single filers and married couples filing jointly, applying to income above specified thresholds (e.g., $10,500 for single filers and $22,650 for joint filers). The bill also establishes new lower tax brackets for 2024-2025, such as 0.25% on the first $1,000 of income for single filers. It eliminates the deduction for federal income taxes when calculating Oklahoma taxable income. This bill directly affects all Oklahoma residents and nonresidents filing individual income tax returns for 2024-2025.
