Across the United States, voters have spoken with a consistent message: protect taxpayers from easy tax hikes. Early counts from several states indicate that supermajority requirements for tax increases enjoyed broad approval, while attempts to introduce new wealth taxes or expand property taxes were largely turned down.
Supermajority Requirements Gain Momentum
Voters in Iowa approved a constitutional amendment mandating a two‑thirds legislative vote before any increase in income taxes. Similar measures are moving forward in Washington state, where Snohomish County’s Proposition 5 and Clark County’s Amendment 25 both seek a supermajority vote for county tax hikes. The only notable defeat came in Utah, where a proposal for a 60 % threshold on ballot‑initiated tax measures was rejected.
Wealth Tax Proposal Falls Flat in California
California’s Proposition 40, the nation’s first attempt to impose a wealth tax, was decisively rejected. The defeat aligns with recent experiences in Europe, where several countries have rolled back wealth taxes after they proved economically harmful.
Mixed Results on Income‑Tax Structure
Colorado’s narrowly passed constitutional amendment would allow a graduated income tax, a step many conservatives view as a misstep toward higher rates. In contrast, North Carolina adopted an amendment capping income taxes at 3.5 %, reinforcing a low‑tax environment. Washington voters also rejected a repeal of the state’s first income tax, keeping the status quo despite longstanding Supreme Court rulings that a graduated tax is unconstitutional; the issue is slated for oral arguments on February 5, 2027.
Property‑Tax Measures Split Along Regional Lines
Wyoming voters turned down a flawed property‑tax proposal that failed to address underlying spending. Tennessee, however, approved a constitutional amendment prohibiting a state property tax, while North Carolina adopted a measure limiting how much local governments can raise property taxes. Florida voters approved a controversial amendment expanding the homestead exemption, a move praised by many homeowners.
Other Notable Ballot Outcomes
Arizona narrowly approved an amendment banning mileage‑based taxes on vehicles. Missouri rejected a constitutional amendment that would have created a public endowment fund aimed at phasing out state taxes.
Lessons for the Mountain West and Texas
Regional leaders in Idaho, Montana, Wyoming and Texas can take note. The strong voter preference for supermajority safeguards suggests that future tax‑increase proposals will face steep hurdles. Texas taxpayers, for example, have long enjoyed a constitutional ban on state income tax, a protection reaffirmed by voters in 2019.
Policy Recommendations
Given the clear voter sentiment, policymakers should consider constitutional amendments that require a supermajority legislative vote before any tax increase. Such safeguards would honor the taxpayers’ desire for fiscal restraint and provide stability for families and businesses alike.
