Overview
- The proposed 2026 Billionaire Tax Act would levy a one-time 5% tax on Californians with net worths above $1 billion, tied to residency on Jan. 1, 2026, with payments due starting in 2027 and eligible to be spread over five years.
- The initiative has not yet qualified for the ballot and still must gather roughly 875,000 valid signatures, with backers led by SEIU‑UHW pitching the tax as a way to offset federal health-care funding cuts.
- Polling is mixed but shows notable support, with a Nestpoint survey finding 60% backing that held at 54% after hearing risks, while a Mellman Group poll showed 48% support and 38% opposition.
- Newsom has intensified his criticism, arguing the one-time levy could shrink the tax base and reduce funding for schools, public safety and other core services without fixing structural budget issues.
- Opposition financing and maneuvering have escalated, including Sergey Brin’s $20 million and Michael Moritz’s $2 million to a new political group and Peter Thiel’s $3 million to anti-tax efforts, alongside reports of some wealthy residents changing addresses, with legal challenges widely expected if the measure advances.
