As of September 2026, California residents are required to pay state taxes on assets held in out-of-state shell companies under Senate Bill 1406. The law effectively closes loopholes previously used to avoid vehicle registration fees and emissions standards.
Why it matters
The legislation aims to curb tax evasion regarding high-end assets like exotic cars and RVs that were previously registered in states like Montana to avoid California fees. By making LLC partners personally liable for unpaid taxes, the state aims to ensure compliance with local emissions and registration laws.
Senate Bill 1406 establishes legal liability for all LLC partners regarding unpaid vehicle taxes, marking a shift from previous years where shell companies in states like Montana were used to bypass California registration costs.

Market Dynamics
The implementation of Senate Bill 1406 reflects a tightening of regulatory oversight on corporate structures previously used to arbitrage tax differences between states. This shift marks a departure from the historical use of Montana-based shell companies to bypass California's specific registration and emissions mandates.
California residents who manage vehicles through out-of-state shell companies now face personal liability for any unpaid taxes and registration fees. These individuals should review their corporate structures to ensure compliance with the new tax obligations to avoid potential criminal charges for nonpayment.
The takeaway
Vehicle owners previously utilizing out-of-state LLCs to register exotic cars or RVs should audit their assets to align with current California tax requirements. The law serves as a firm reminder that local emissions and registration laws remain binding regardless of the corporate structure chosen for the asset.
What happens next
In 2028, Leno's Law is scheduled to take effect, which will extend smog check exemptions to classic vehicles manufactured in the late 1970s and early 1980s.
