California Cracks Down on Tax Fraud with Montana Plates

Published on March 14, 2026 | Translated from Spanish

California authorities have intensified the pursuit of the well-known Montana legal loophole. This scheme allows state residents to register luxury vehicles and RVs in the name of a company in Montana, thereby avoiding California's sales tax and registration. It is estimated that the state loses about 10 million dollars annually due to this practice.

The hack of LLCs and the tax systems' response 🕵️

Technically, the scheme operates by creating an LLC (Limited Liability Company) in Montana, a state without sales tax on vehicles. The real owner transfers the title to this legal entity, which then registers the vehicle obtaining Montana plates. To counter it, California's CDTFA is auditing transactions and cross-referencing massive data. They are reviewing all sales since 2023 that resulted in Montana plates, employing algorithms to detect suspicious patterns and focusing on high-value dealerships.

Your Montana LLC doesn't come with a free lawyer ⚖️

It seems that the idea of saving a few thousand in taxes with a $50 LLC didn't work out so well. Now, 81 criminal investigations for perjury and evasion remind us that the state of California has a very good memory for license plates, especially those featuring a mountainous landscape on a Beverly Hills Range Rover. Perhaps the next life hack fiscal will simply be to pay the taxes. Less exciting, but with a better credit score.
