Providing that future personal and corporate income tax rate and privilege tax rate decreases be contingent on exceeding tax receipt revenues.

SB 259 requires that future personal and corporate income tax rate decreases in Kansas can only occur if actual state tax revenues exceed an inflation-adjusted baseline revenue target set for fiscal year 2024 ($10.004 billion). The bill establishes a process where, each August 15, the state budget director compares the previous year's actual tax collections to revenues adjusted for inflation; only if collections exceed this target will tax rates be reduced. Tax rate reductions must first lower the lowest income tax bracket (starting at 3.1% for 2018-2023) until it reaches 4.5%, then reduce higher brackets and surtaxes until the combined rate equals 4.5%. This bill directly affects all Kansas taxpayers who pay state income tax by tying future rate cuts to specific revenue performance.
