Are you ready for spring? It appears members of Missouri’s general assembly certainly are. Before lawmakers left Jefferson City for spring break a couple of weeks ago, they passed a flurry of bills, including an income tax cut. If enacted, House Bill (HB) 798 would, among other things, eventually lower Missouri’s top individual income tax rate to 3.7% (from 4.7% today).
Going into the 2025 legislative session, it was clear that income tax reform was going to be a hot topic. Not only was it a top priority listed in the Institute’s 2025 blueprint, but numerous bills were also filed before the session began both to incrementally lower the income tax rate and to eliminate the tax altogether. Then, during his first State of the State address, Governor Kehoe officially stated his support for eliminating the individual income tax.
As my colleagues and I have written for many years, there are many good reasons for Missouri to abandon its reliance on the income tax. Decades of economic research have shown that the income tax is one of the most economically damaging forms of taxation, penalizing workers for their productive pursuits. But in recent years, 25 states (not counting Missouri) have lowered their income taxes, including many of Missouri’s neighbors, which should only increase our state’s urgency for meaningful income tax reform.
It’s no coincidence that year after year the fastest-growing states across the country are those without income taxes. If Missouri is serious about joining those states—and we should be—bold action in Jefferson City is necessary. While Missouri’s elected officials have been successful at lowering the state’s top individual income tax rate by 1.3% since 2014 (from 6% to 4.7% today), Missouri is still one of the states most reliant on income tax revenue.
Eliminating the income tax in a fiscally responsible way will not necessarily be easy given that Missouri’s budget has nearly doubled in size in recent years. But the process must start with a single step, and lowering the rate incrementally to 3.7% (what HB 798 proposes) is a great place to start. As lawmakers enter the home stretch of this year’s legislative session, there’s still a lot of work to be done if eliminating the income tax is truly the goal. Time will tell if their actions match their stated priorities.
