States Eye Wallets of Richest Residents With Income-Tax Measures

Voters in as many as four states in November will consider higher levies on their wealthiest residents as income inequality steers liberal activists and politicians toward more progressive taxation.

Colorado and Maine may raise taxes on top earners, while Minnesota is looking to apply the state’s Social Security tax to high incomes to care for senior citizens and people with disabilities. California voters could extend by 12 years a soon-to-expire income-tax increase on the wealthy, while the state’s most populous county, Los Angeles, is eyeing a new tax on millionaires to pay for homeless services.
