Voters usually decide one or two income or wealth tax measures a year. This midterm season, there are nine

Voters in nine states and counties will decide income or wealth tax measures this midterm season, a sharp increase from the typical one or two per year. Colorado, Washington and Cook County, Illinois, are weighing taxes on top earners, while other states are pursuing measures to make tax increases harder to raise. The surge reflects growing tension over how states fund services amid fiscal pressure and debates over tax burden distribution. The outcomes could reshape state revenue structures and influence how other jurisdictions approach high-earner taxation. Watch for results in Colorado, Washington and Cook County, as well as whether anti-tax-hike measures advance elsewhere.
