California prosecutors have charged 14 people accused of using a Montana registration scheme to avoid paying state taxes on luxury and exotic vehicles, according to authorities investigating hundreds of high-end car sales. Officials said the charges stem from an effort by some California residents to register vehicles through Montana-based limited liability companies instead of registering the cars in California, where higher taxes and registration fees apply.
Authorities reported that the investigation centers on a method commonly known as the Montana license plate loophole. In these arrangements, buyers form an LLC in Montana and register their vehicles under that entity. Because Montana has no vehicle sales tax and lower registration costs, the setup can significantly reduce the upfront taxes and recurring fees associated with owning expensive vehicles in California.
Investigators said the practice becomes illegal when the vehicles are actually owned and operated by California residents who do not live or conduct business in Montana. In those cases, authorities determined the paperwork can misrepresent where the vehicle was purchased, stored, and used. Officials allege that some buyers and dealers worked together to create documentation suggesting the vehicles were purchased and operated outside California.
According to prosecutors, the 14 individuals charged in the case face allegations including conspiracy, filing false sales tax returns, failing to file tax returns, perjury, and money laundering. Authorities said the charges reflect an effort to hold individuals accountable for submitting fraudulent records tied to the registration of high-value vehicles. Investigators determined the alleged scheme allowed some owners to avoid paying large tax bills tied to exotic car purchases.
The investigation also uncovered a broader network of dealerships involved in similar transactions. Authorities reported that roughly 500 California dealers have been identified as part of the inquiry. Officials said those dealerships conducted more than 2,500 vehicle sales since 2023 in which the buyers registered their cars in Montana.
Many of the vehicles tied to the transactions were high-end performance and exotic models. Investigators identified Lamborghinis, Ferraris, McLarens, and high-performance Porsche models among the vehicles registered through Montana entities. Some filings also referenced a BMW M2 among the cars included in the investigation.
Officials said the alleged scheme has cost the state significant tax revenue each year. Authorities estimate the practice has resulted in more than $10 million in lost tax revenue annually. Investigators said the cases under review involve vehicles worth hundreds of thousands or even millions of dollars.
Several of the vehicles highlighted in the investigation represent some of the most expensive road cars sold in recent years. Authorities reported that filings tied to the investigation included a McLaren Elva valued at approximately $1.8 million, a Porsche 918 Spyder valued around $1.5 million, and a Ferrari F12TDF valued at about $1.26 million. Each of those vehicles would normally generate significant sales tax obligations if registered in California.
Investigators began examining the registration practices several years ago. Authorities reported that California’s Department of Motor Vehicles launched more than 80 investigations related to the Montana LLC strategy beginning in 2023. Those inquiries eventually expanded into a multi-agency investigation involving the California Department of Tax and Fee Administration and the California Department of Justice.
Officials said the investigation uncovered activity dating back to at least 2018. According to investigators, some dealerships allegedly assisted buyers by preparing documents that misrepresented where the vehicles were purchased or used. Authorities said those documents were submitted to state agencies in connection with vehicle registration and tax filings.
Investigators said the records included forms submitted to the California Department of Tax and Fee Administration as well as registration documents filed with the Department of Motor Vehicles. Authorities reported that the paperwork allegedly created the appearance that the vehicles were purchased and operated outside the state, even though they were used primarily in California.
The potential financial incentives involved in these arrangements are significant. California’s vehicle sales tax generally ranges from about 7.75 percent to more than 10 percent depending on location. In some regions, combined local and state tax rates can exceed 11 percent.
For extremely expensive vehicles, those tax rates can translate into large payments at the time of purchase. A vehicle priced at $1.8 million, for example, could generate a sales tax obligation exceeding $170,000 in certain areas of the state. In addition to sales tax, owners must also pay recurring registration fees tied to the value of the vehicle.
Montana’s tax structure creates a stark contrast. The state has no sales tax on vehicle purchases, and registration fees are dramatically lower than California’s. That difference has made Montana LLC registrations appealing to some owners of expensive vehicles who are attempting to reduce ownership costs.
Authorities said the investigation also revealed that some dealerships were actively assisting buyers in setting up the arrangements. Officials reported that Beverly Hills was identified as the city with the highest number of dealerships involved in the suspected transactions.
State agencies had previously warned dealers about the risks associated with the registration strategy. In December 2024, the California Department of Tax and Fee Administration sent warning letters to dealerships advising them not to use out-of-state LLC structures to register vehicles for California buyers.
Authorities said the letters made it clear that dealerships participating in the process could face enforcement action if the vehicles were actually owned and operated by California residents. Investigators reported that despite the warnings, some dealerships allegedly continued facilitating the transactions.
The case highlights the ongoing scrutiny surrounding vehicle registration practices tied to high-value cars. Luxury vehicles often carry large tax obligations due to their purchase price, making registration strategies an area of interest for enforcement agencies.
For buyers, the financial difference between states can be dramatic. In addition to sales tax savings, Montana’s registration fees are far lower than California’s. California charges a registration fee that begins at roughly 0.65 percent of the vehicle’s value in the first year, declining gradually over time.
For a million-dollar vehicle, that structure can add thousands of dollars in annual costs. In contrast, Montana registration fees for new vehicles are capped at a much lower amount. That gap has helped fuel the popularity of the Montana LLC strategy among some exotic car owners.
Authorities said the ongoing investigation aims to identify individuals and businesses involved in the alleged scheme. Prosecutors confirmed that the 14 charged individuals now face multiple criminal allegations tied to fraudulent tax filings and vehicle registrations.
Officials reported that the case remains active as investigators continue reviewing dealership transactions and registration records tied to luxury vehicles sold in California. The individuals charged are now facing legal proceedings connected to the alleged scheme, while the broader investigation into the registration practices remains ongoing.
