Can States Tax You After You Move? Inside the Billionaire Wealth Tax Showdown

We see it all the time here in our Maitland tax office and across the greater Orlando area. Small business owners relocate to Florida—often settling in places like Winter Park, Lake Nona, or Davenport—seeking a friendlier financial climate. But what if your former state tries to keep taxing you long after you have unpacked your boxes?

That exact scenario is sparking a major legal showdown over California’s proposed 2026 Billionaire Tax Act. This ballot initiative would hit qualifying former residents with a one-time 5% tax on their worldwide net worth, using January 1, 2026, as the residency benchmark.

Inside the Proposed Wealth Tax

If approved for the November 2026 ballot, this measure targets individuals or trusts with a net worth of $1 billion or more. Proponents claim it will raise massive revenue for healthcare and social programs. However, the California Legislative Analyst’s Office (LAO) warns that taxing departed residents could trigger an exodus, potentially draining hundreds of millions in ongoing income tax collections.

The Federal Response: H.B. 7619

This aggressive revenue strategy hasn't gone unnoticed in Washington. U.S. Representative Kevin Kiley introduced the Keep Jobs in California Act (H.B. 7619) to block states from imposing retroactive taxes on former residents' assets. Kiley described the wealth tax as an “unprecedented attempt” to impose taxation on individuals who have already left the state.

Constitutional Hurdles and Migration Risks

Taxing people who no longer live in your jurisdiction raises distinct constitutional questions, specifically regarding:

  • Due Process protections
  • The constitutional right to travel
  • Commerce Clause limitations
  • The scope of state authority over worldwide assets

Adding to the complexity, competing California ballot measures might require a two-thirds voter threshold for new one-time taxes or prohibit new taxes on personal savings, creating a tangled web for taxpayers.

Navigating State Tax Residency

While a billionaire wealth tax might feel miles away from your Altamonte Springs small business, the core lesson is critical: establishing clear domicile intent is vital. Residency isn’t just where you get your mail—it can determine whether your wealth is taxable. If you are shifting your operations, meticulous bookkeeping and strategic tax planning are your best defense.
