The SEIU healthcare union is pushing for a billionaire tax in California.

What we found

Supports. CBS News reports that union leader Dave Regan and SEIU United Healthcare Workers West led a petition drive to place the one-time 5% billionaire tax (Proposition 40) on the November ballot.[1]

Supports. Hcamag reports SEIU-UHW has been pushing the California Billionaire Tax Act and that the union gathered enough signatures to qualify it for the November 2026 ballot.[2]

Supports. Accounting Today quotes SEIU-UHW president Dave Regan as the healthcare-workers union pushing the billionaire tax, which was published before the claim date.[3]

Supports. 10News reports that the union behind the measure, SEIU United Healthcare Workers West, projects it would raise $100 billion over five years.[4]

Context. Later reporting (late October 2026) describes the union's campaign continuing and opposition spending growing, but this does not change the claim's status as of 2026-10-16.[5][6][7]
