HB 1539 reduces Oklahoma's top individual income tax rate from 5.50% to 4.75% for taxable years beginning January 1, 2024, and beyond. It directly affects all Oklahoma residents and nonresidents filing individual income tax returns, applying the new rate to income above specific thresholds (e.g., $7,250 for single filers and $12,850 for married joint filers). The bill revises tax brackets to lower the top marginal rate while keeping lower brackets unchanged, with the reduction contingent on a State Board of Equalization determination. This change lowers tax liability for most higher-income earners under the current structure.
