Doctors worry swapping income taxes for sales taxes will hurt patients; GOP lawmaker pushes back
Missouri voters will decide this summer whether to replace the state’s income tax with higher sales taxes under Amendment 5, a proposal that has drawn sharp debate over its potential impact on healthcare costs. Healthcare professionals warned that the measure could lead to increased expenses for medications, medical services, and hospital visits, while supporters argue it would boost economic growth.
On Thursday, a group of healthcare workers organized by Progress MO urged voters to reject the amendment, citing concerns that healthcare services might be taxed for the first time. “Forces my patients to decide paying for their prescriptions or paying for a roof to be over their head,” said Dr. Christian Hendrix, a physician who described the proposal as a risk to vulnerable populations.
State Rep. Bishop Davison (R), a Republican lawmaker, defended the measure, calling income taxes a “penalty on productivity” and stating that healthcare would remain exempt. “Almost half of healthcare federally is exempt from taxation, secondly, almost every single state already exempts it and Missouri will be no different,” he said, referencing the governor’s assurance that healthcare would not be taxed.
Why the Proposal Matters
The amendment’s core goal is to shift Missouri’s tax structure, replacing income taxes with higher sales taxes. Lawmakers argue this would make the state more competitive and reduce the tax burden on some residents. However, healthcare professionals warn that the lack of clarity on which sales taxes would increase leaves room for potential costs to rise, particularly for essential medical services.
A March poll by Saint Louis University found a majority of Missourians support relying more on sales taxes than income taxes, reflecting broader public sentiment on tax policy. Yet the proposal’s implications for healthcare remain contentious, with doctors emphasizing the risk of increased financial strain on patients.
What May Happen Next
If Amendment 5 passes, the Missouri Legislature would determine which sales taxes to increase, though healthcare exemptions are expected to remain in place. However, the lack of specific details has left uncertainty about how the policy would affect healthcare affordability. Analysts suggest the outcome could hinge on legislative decisions and public awareness of potential consequences.

Opponents of the measure plan to continue advocating against it, while supporters are likely to emphasize economic benefits. The final vote will depend on voter education and the ability of both sides to shape public perception ahead of the summer election.

Expert Insight: Samantha Carter, a health policy analyst, notes that while tax shifts can influence healthcare costs, the direct impact depends on how exemptions are structured. “The debate highlights a common tension between economic policy and healthcare access, where broad tax changes can have unforeseen consequences for vulnerable groups,” she said.
