The evidence

Income tax timeline

Less than a penny for the city. Not a penny more at checkout.

State leaders enacted a fixed, multi-year reduction in the individual income-tax rate. Municipal services would benefit from the same kind of scheduled, predictable planning.

The Partnership does not ask to slow, change, or reverse the income-tax reduction. It is shown here for one reason: it proves the State already plans major revenue on a long-range schedule — exactly the planning cities are asking for.

The fixed enacted schedule

House Bill 1 sets the individual income-tax rate for each tax year from 2026 through 2030. These rates apply to individual taxable income exceeding $10,000.

Reductions after 2030

Reductions after 2030 are conditional under the statutory revenue-and-reserve triggers. They are not part of the fixed schedule above, and they are shown separately here for that reason.

Under the enacted law, a reduction after 2030 happens only in a year when the statutory revenue-and-reserve conditions are met. No post-2030 reduction is scheduled in advance.

University Research Center analysis of HB 1

The University Research Center modeled the enacted reductions against a baseline. Its published findings include:

  • Average modeled General Fund growth of 0.6 percent annually through FY2040 under HB 1, versus 3.3 percent in the baseline.
  • General Fund growth continuing at a lower average rate through FY2040 under the enacted schedule — the reason municipal needs should be scheduled now, before future growth is fully committed.
  • Modeled long-run gains of 0.3 percent real GDP, 0.3 percent employment, 0.4 percent personal income, and 0.8 percent population.

What this means for municipal planning

State leaders have placed income-tax reductions in a long-range fiscal schedule. Municipal services should receive the same kind of predictable planning before future revenue growth is fully committed.
