For years, wealthy car buyers exploited a quirky registration loophole to avoid paying steep sales taxes on their million-dollar vehicles. By forming a Montana LLC, they registered their flashy supercars-like the McLaren Elva, Porsche Carrera GT, and Ferrari TdF-in Montana despite living elsewhere, sidestepping hefty taxes in their home states. Now, California has begun cracking down on this widespread scheme, indicting 14 individuals for tax fraud tied to vehicles registered in Montana but primarily driven and garaged in California.
These 14 defendants collectively own cars exceeding $20 million in value. The California Attorney General’s office emphasized that sales tax revenues are critical funding for the state’s infrastructure, schools, and social programs. While California’s sales tax rates rank among the highest in the US, the state insists that residents must not game the system by pretending their luxury vehicles hail from tax-friendly Montana.
This type of tax evasion isn’t new. Several other states have been watching and slowly tightening rules around out-of-state vehicle registrations linked to shell LLCs. Yet California’s enforcement effort signals a more aggressive stance, reflecting frustration that some wealthy individuals exploit legal gray areas to gain unfair advantages on short-term savings. Considering the taxes on a $1 million-plus supercar can easily top six figures, the financial stakes are huge.
There’s also an ironic cost-benefit angle: if you can afford an ultra-expensive car, the $100,000-plus tax bill is hardly catastrophic-and it supports the very roads and services the vehicle depends on. For those unwilling to pay, the straightforward alternative remains relocating legally to Montana or another state with favorable vehicle tax policies.
Looking ahead, other states may follow California’s lead, increasing scrutiny on out-of-state vehicle registrations. Enforcement will hinge on tracking where cars actually reside and are used, combating an evasion tactic that exploits the ease of creating LLCs across state lines in the internet age. Until then, spotting a Montana plate on a Ferrari in Los Angeles or San Francisco might mean riskier business than ever before.
