Final passage came on a 34-3 Senate vote to lower the tax to 3.5% from 4% at the start of 2026. The bill goes to Democratic Gov. Andy Beshear, who has said he supports the tax cut. It continues a downward trend in the personal income tax rate since the GOP gained full control of the legislature in 2017.
