Push for Millionaire Tax Spreads to More States as Income Inequality Debate Heats Up

More states are moving to impose additional taxes on high earners in 2026, following the lead of states like California and New York that already have millionaire surcharges, according to CNBC's personal finance coverage.

Advocates for the millionaire tax say the revenue is needed to fund education, healthcare, and infrastructure. Several state legislatures have introduced bills this session that would add a surcharge of one to four percentage points on income above $1 million.

Opponents argue the taxes will push wealthy residents and businesses to lower-tax states, reducing the overall tax base. They point to data from states like California, where high earners have relocated to Nevada, Texas, and Florida in recent years.

The debate comes as the federal estate tax exemption rose to $15 million per person in 2026, reducing the federal tax burden on wealthy families. Critics say that shift makes state-level millionaire taxes more important for funding public services.

At the federal level, the One Big Beautiful Bill Act made several changes that affect high earners. The standard deduction for married couples filing jointly rose to $32,200 for 2026. The top individual tax rate stays at 37 percent for incomes above $640,600 for single filers and $768,700 for married couples filing jointly.

Financial planners say high-income individuals in states considering new surcharges should review their residency and business structures. Establishing legal residency in a lower-tax state before a new law takes effect can be a legitimate tax planning strategy, though it requires genuine changes to where a person lives and works.

The I-Bond rate for 2026 is set at 4.26 percent through October, offering a safe, inflation-protected savings option for those looking to preserve purchasing power.
