For years, I have argued that Missouri’s spending trajectory needed correction, and a new report from the state auditor confirms that conclusion.
Shortly before the end of last year, the auditor’s office released a report urging lawmakers to take “immediate action” to curb the trend of deficit spending before more drastic cuts become necessary. For longtime readers of the Show-Me Institute blog, this assessment will sound familiar. The report reinforces concerns that have been visible in Missouri’s budget data for more than half a decade.
Reviewing recent revenue and spending trends helps illustrate the problem. Between 2020 and 2025, Missouri’s general revenue collections increased by 45.8 percent, largely driven by income and sales tax growth. Over the same period, general revenue expenditures increased by 53.4 percent. That spending growth more than doubled the rate of inflation, which rose 24.5 percent during those years. Even strong revenue growth was not enough to keep pace.
This imbalance was made possible by a temporary windfall. Although Missouri operates under a constitutional balanced budget requirement, lawmakers were able to commit to higher spending because of a large influx of federal COVID relief funds, combined with stronger-than-expected tax collections. That surge produced a record general revenue balance of nearly $6 billion in 2023. Rather than treating those conditions as temporary, the state locked in higher ongoing spending through pay raises and program expansions, among other things. Since then, the surplus has been largely exhausted.
Looking ahead, fiscal pressures are likely to get worse. Governor Kehoe’s recent budget recommendations project a decline in expected revenues this fiscal year and only minimal growth in Fiscal Year 2027. The outlook deteriorates further when you consider the chance of an economic downturn. Using the worst three-year revenue decline Missouri experienced between 2003 and 2025, the auditor estimates the general revenue fund would be depleted by 2027. Under that scenario, the state would face a deficit exceeding $3.8 billion. And while Missouri’s Budget Reserve Fund (rainy day fund) holds approximately $950 million, as I’ve written before, constitutional restrictions sharply limit its usefulness in addressing an ongoing budget shortfall.
As the general assembly begins working on next year’s budget, the auditor’s report should remain front of mind. There’s still time to rein in the state’s out-of-control spending if Missouri’s lawmakers are willing to start making the tough decisions that right-sizing government entails. The question is no longer whether adjustment is needed, but instead how long until fiscal disaster strikes.
