Google Cofounders Brin and Page Relocate LLC from California

Towards the end of 2025, an enterprise associated with Sergey Brin and Larry Page, Google's cofounders, left California, circumventing an impending wealth tax aimed at the affluent in the state.

Originally formed in 2006, T-Rex LLC, tied to Brin and Page, transitioned from being a California-based LLC to being established as T-Rex Holdings in Delaware on December 24, 2025, as per documents seen by Business Insider.

For two decades, records have shown Brin and Page as managers of the LLC at its Palo Alto location. The latest documentation lists a Reno, Nevada address as the primary office of T-Rex Holdings, with both Brin and Page continuing as its managers.

Neither Brin's nor Page's representatives have responded to requests for remarks.

This relocation occurs amidst a trend where California's wealthiest individuals are contemplating leaving the state. A proposed ballot measure could compel approximately 200 of California's billionaires to pay a one-time 5% tax. If this measure passes in the November vote, it would be retroactive for those residing in California from the start of 2026, as a means to mitigate the state's significant budget shortfall.

Strategic Financial Moves

This week, it was first reported by Business Insider that Page officially cut ties with California in late December by reorganizing his family office as a Delaware LLC. Additionally, he's incorporated other ventures in Delaware recently, one involving influenza research investment and another focused on aerial vehicle developments.

The specific role of the LLC linked to Brin and Page is not disclosed. Official filings define T-Rex Holdings as a 'management company.' Similar to many high-net-worth individuals, Brin and Page utilize LLCs for asset management or investments, generally with minimal public visibility. The company's name might reference Stan, a T. rex statue that prominently resides at Google's Mountain View campus.

Brin has long-standing ties with California through various entities, including his namesake family foundation and Bayshore Global Management, his family office. Unlike Page, there's no indication from records of any other Brin-associated entities leaving California.

Ranked by Bloomberg's Billionaires Index, Page and Brin stand as the second and fourth wealthiest worldwide, each amassing fortunes greater than $250 billion.

Potential Legislative Impacts

For the tax proposal to reach the state ballot in November, it needs a sufficient number of signatures. If voters approve, it would be effective retroactively, implying anyone wishing to dodge the tax should have relocated before December 2025 ends.

California considers various factors when establishing residency, such as time spent within the state and significant business engagements.

Celebrity lawyer Alex Spiro issued a December 11 letter to Governor Gavin Newsom, urging him to halt the proposal. He warned of a potential mass movement of both capital and creativity out of California if the wealth tax proceeds. 'Our clients have expressed their intention to permanently relocate should this tax be enacted,' Spiro stated.

Diverging Paths for Tech Icons

After stepping away from executive positions in 2019, Brin and Page have charted distinct courses. Brin has re-engaged in active projects at Google, whereas Page maintains a passive role as a major shareholder.
