State Tax Reach: What California's Wealth Tax Fight Means for Business Relocation

If you relocate your business or family to a new state, can your former state still tax your wealth? That question is driving a growing legal and political showdown over California’s proposed 2026 Billionaire Tax Act. The ballot initiative seeks to levy a one-time 5% tax on the global net worth of billionaires who were California residents as of January 1, 2026—even if they subsequently move away.

Supporters claim it will generate massive revenue for healthcare and social programs. However, critics caution it represents an aggressive overreach that could trigger high-profile relocations and attempt to capture revenue from individuals who no longer live there.

Inside the Proposed 2026 Wealth Tax

If voters approve the measure in November 2026, the legislation would:

  • Impose a one-time 5% excise tax
  • Target individuals and trusts with a net worth of $1 billion or more
  • Assess global assets using a January 1, 2026, residency benchmark

While the primary goal is funding public services, the California Legislative Analyst’s Office (LAO) warns the long-term impact could backfire. If affected individuals relocate to protect their capital, the state could face hundreds of millions of dollars in ongoing annual income tax losses.

The Federal Response: Blocking Retroactive Reach

To prevent states from crossing jurisdictional boundaries, U.S. Representative Kevin Kiley introduced the Keep Jobs in California Act (H.B. 7619). This federal bill aims to block any state from applying retroactive asset taxes on nonresidents for periods before the legislation was passed.

Kiley labeled the state initiative an unprecedented attempt to tax former residents. Importantly, the federal act does not restrict states from taxing current residents; it simply establishes boundaries against post-departure wealth taxation.

Why Proactive State Tax Planning Matters

At Lizza & Carullo CPAs & Advisors, we know that state revenue departments—whether in California or right here in New Jersey—employ stringent residency audits based on domicile, days spent in-state, and operational ties. Attempting to tax departed residents brings up complex constitutional questions regarding Due Process, the Commerce Clause, and the right to travel.

Even if your company is not hitting the billion-dollar mark, this dispute proves that aggressive state tax policies are a reality. Whether you are scaling a $3M service business, optimizing multi-entity real estate holdings, or planning a strategic relocation out of New Jersey, changing your mailing address is never enough.

Multiple competing ballot measures could complicate this further, including proposals to require a two-thirds voter threshold for new taxes or to protect retirement assets.

For business owners, residency requires strict operational discipline and clear financial structure. If you need visibility into how state taxes impact your long-term wealth, cash flow, and entity structure, reach out to our advisory team to map out a proactive, tax-efficient strategy.
