Why It Matters
Michigan lawmakers finalized the state budget for fiscal year 2026-2027 without adopting new revenue sources to offset anticipated cuts to federal funding for Medicaid and food assistance programs. The decision leaves the state vulnerable to service reductions for low-income residents as federal policy shifts.
What Happened
State budget leaders completed negotiations on the FY 2026-2027 budget while declining to include tax increases or other revenue-raising measures. The omission comes as Congress enacted the “One Big, Beautiful Bill Act” last year, which is expected to reduce federal funding flowing to Michigan for Medicaid and the Supplemental Nutrition Assistance Program (SNAP) over several years.
Governor Gretchen Whitmer had proposed tax increases on tobacco and gambling in her executive budget submission, but these measures did not survive final legislative negotiations. The state currently maintains a flat income tax of 4.25% and has no wealth taxes on its books.
Michigan has already expanded its own spending on SNAP administration and staff hiring to comply with new federal eligibility requirements being rolled out by Washington, straining the state’s ability to absorb future federal reductions without corresponding revenue growth.
By the Numbers
40% — Share of Michigan households already struggling to afford basic needs
4.25% — Michigan’s flat income tax rate
9.49% — Cap on Michigan’s total state tax collections as a percentage of personal income under the Headlee Amendment
$14 billion — Additional revenue the state would have collected if tax collections had kept pace with personal income growth since 2000, when the Headlee cap was last met
38th — Michigan’s national ranking for combined state and local taxes as a percentage of personal income
Constitutional Constraints on Revenue
Michigan voters approved the Headlee Amendment in 1978, which caps the state’s total tax collections at 9.49% of personal income. The state has not exceeded this threshold since 2000. If Michigan’s tax revenue had grown in line with personal income over the past quarter-century, state coffers would contain an additional $14 billion, according to budget analysis.
The amendment has become a structural constraint on the state’s ability to fund services without either raising tax rates or broadening the tax base—both politically difficult options. Whitmer’s defeated proposals for tobacco and gambling taxes represented attempts to raise revenue within existing policy frameworks rather than challenge the constitutional limit directly.
Zoom Out
Michigan’s revenue challenge reflects a national pattern of states facing federal retrenchment in social safety net programs. The Trump administration has signaled intention to restructure federal Medicaid matching and reduce food assistance spending as part of broader deficit reduction efforts. States with constitutional or statutory limits on revenue collection face steeper adjustment pressures than those with greater fiscal flexibility.
Michigan currently ranks 38th nationally in combined state and local taxes as a percentage of personal income, placing it neither at the high end of state tax burdens nor at the low end—a middle position that offers less political room to raise rates without triggering comparisons to higher-tax states.
What’s Next
The state will begin implementing the FY 2026-2027 budget without identified revenue sources to backstop federal cuts. Budget analysts and advocacy groups have warned that without legislative action to raise revenue or redirect existing appropriations, the state may face difficult choices on Medicaid eligibility, SNAP benefit levels, or other safety-net services as federal funding declines over the coming years. The governor and legislature may revisit revenue proposals during budget adjustments or the next fiscal year cycle, though political appetite for tax increases remains uncertain.
