When I pull into a valet line at a nice restaurant and spot a bright red Ferrari sitting next to a blacked-out Lamborghini Huracan, I do what any insurance guy does. I look at the plates.
Montana.
I smile every time. Not because I am judging the owner in any negative way. I smile because I know exactly what is going on, and honestly, it is a fascinating intersection of American tax law, car culture, and wealth management that most people have never heard of. Let me walk you through it, because if you own a collector car, dream of owning one someday, or simply wonder why half the six-figure vehicles in Beverly Hills seem to be registered in Big Sky Country, this article is for you.
What People Actually Mean by the "Montana Law"
There is no single piece of legislation called the Montana Supercar Law. What people are referring to is a combination of three things that happen to exist in Montana at the same time:
No statewide sales tax
No residency requirement to register a vehicle through a Montana LLC
Simple, business-friendly vehicle registration rules
When you put those three things together, a buyer can create a Montana limited liability company, purchase a vehicle through that company, title the car there, and avoid paying the 7 to 10 percent sales tax that most states charge. On a $400,000 Ferrari, that is a $28,000 to $40,000 savings. On a $1.2 million McLaren Senna, do the math yourself.
Montana did not design this system to help tech founders dodge taxes on supercars. The state was built for ranchers, agricultural businesses, and tourism operators who routinely own equipment through business entities. The recreational vehicle industry, boating industry, and aircraft industry discovered the same thing decades ago. Exotic car collectors found it later, and by the 2010s, entire law firms were charging a flat fee to set up your Montana LLC and register your Porsche while you drove it home to Los Angeles.
Why People with One Nice Car Usually Have Several
Here is something I observe constantly in my work. When someone calls me about insuring a collector car, by the time we are done talking, we are almost always talking about more than one vehicle. It is the nature of a collection. You do not just own a 1969 Camaro SS. You own the Camaro, and a 1972 Chevelle, and a 2006 Ford GT because you happened to find one in the right color, and then one day a 1985 Countach shows up and you cannot say no.
Collections grow. That is what they do. And the owners of those collections are not just hobbyists. They are stewards. They care about provenance, about proper storage, about documentation, and about making sure these vehicles survive for the next generation to appreciate. These are not people driving their cars to the grocery store. These are people who treat their garage like a museum.
Which is exactly why, when something does happen, the insurance conversation becomes incredibly important.
The Carriers That Actually Understand Collector Vehicles
Not all insurance companies are built the same, and nowhere is that more obvious than in the collector car world. Standard auto insurance was designed for vehicles that depreciate. It values your car based on what the market says it is worth the day of the loss, minus your deductible. For a 1967 Shelby GT500 or a 2015 LaFerrari, that framework falls apart immediately.
At MM Insurance, we work with carriers that actually understand what you own.
Hagerty is the gold standard for collector vehicles. They write agreed value policies, meaning you and Hagerty agree on the value of the car upfront, document it properly, and if the car is totaled, that is the check you receive. No negotiation. No depreciation argument. No sending an adjuster who has never heard of a numbers-matching engine. Hagerty also brings something most carriers do not: a genuine passion for car culture. The way they handle claims, the way they communicate with owners, and the resources they provide around valuation and documentation are second to none in this industry.
Pure Insurance and Chubb serve high-net-worth clients with collections that extend well beyond cars. If your garage is part of a larger picture that includes a vacation home, fine art, jewelry, and a boat, these carriers write policies that treat your entire collection as the unified asset it really is.
Berkeley Classics rounds out the specialty market for vehicles that fall outside the standard collector categories, including custom builds, race-prepped cars, and exotics with heavily modified values.
The common thread across all of them is this: they understand that when a collector car is gone, no check will truly make you whole. But they get as close as possible, and they do it without the fight.
The Loophole Is Getting a Lot Less Quiet
For a long time, the Montana LLC strategy was one of those things that wealthy car buyers knew about and high-tax states largely ignored. That era is over.
California has launched the most aggressive enforcement action in the history of this loophole. As of early 2026, the California Department of Tax and Fee Administration and the DMV have identified nearly 500 dealerships involved in more than 2,500 suspicious luxury vehicle sales since 2023. The state has opened more than 400 investigations into individual buyers and charged 14 people, including auto dealers and customers, with conspiracy to commit tax evasion, filing false sales tax returns, money laundering, and perjury. The complaint involves more than $20 million in luxury car purchases including a McLaren Elva, a Porsche 918 Spyder, and a Ferrari F12 TdF.
California DMV investigators are now using automated plate readers, cross-referencing insurance filings, and even monitoring geotagged social media photos to catch Montana-plated vehicles that spend most of their time in California driveways.
California SB 1406, introduced in 2026, would close the loophole at the statutory level by expanding the state's definition of residency to include shell companies whose members are California residents. Utah and other states are running parallel investigations. The legal math is straightforward: if you live in the state, garage the car in the state, and drive it in the state, the state believes you owe the state's taxes. The Montana title is not the shield it used to be.
The Insurance Dimension Nobody Talks About
Here is where I want to be direct with you as an insurance professional. The Montana LLC strategy creates a coverage question that most people never ask their agent, and it is a question that matters.
If your vehicle is titled through a Montana LLC but primarily garaged and driven in another state, your insurer needs to know that. Specialty carriers like Hagerty are experienced with collector vehicles registered through LLCs, and they can write policies that properly reflect the actual use and garaging location of the vehicle. But the policy language matters, and the representations you make about where the car lives matter.
A claim denial on a $300,000 vehicle because the policy was written based on a Montana address when the car never left your Chicago garage would be devastating. The best carriers will work with you on this. The conversation just needs to happen.
Beyond the registration question, collector car policies have specific use requirements. Agreed value coverage typically comes with restrictions on daily use, mileage allowances, and storage standards. If you are running your classic car through a Montana LLC and it is parked in a climate-controlled storage unit in Waukesha, there are right ways to structure that policy and wrong ways.
I have these conversations regularly. They are not complicated once you are working with the right agent and the right carrier.
If You Have a Collection, Protect It the Right Way
I grew up in Wisconsin. I have watched car culture up close my whole life, from muscle cars to modern supercars to the guys who show up to car meets in immaculate 1950s trucks they have been restoring for twenty years. The people who own these vehicles love them in a way that does not translate to a balance sheet.
When I sit down with a client who has a garage full of collector cars, what I am trying to do is make sure that if the worst happens, the financial piece is the last thing they need to think about. The emotional piece is already going to be hard enough.
Montana plates or Wisconsin plates, the carrier that insures your collection should be one that knows what it is insuring, agrees with you on its value before a loss ever happens, and has a track record of making collectors whole when the time comes.

Frequently Asked Questions
What is the Montana LLC loophole for vehicles?
It is the practice of creating a Montana limited liability company and registering a vehicle through that entity to avoid paying sales tax in your home state. Montana has no sales tax, so buyers can legally title a car there even if they do not live in the state.
Is the Montana LLC vehicle registration strategy legal?
The Montana registration itself is legal. The problem arises when a vehicle is primarily garaged and driven in another state, because that state may still consider you responsible for its sales tax or use tax. Several states including California are actively prosecuting individuals who use the strategy fraudulently.
What states are cracking down on Montana plate registrations?
California has taken the most aggressive stance, with criminal charges filed in 2025 and joint enforcement by the CDTFA and DMV underway in 2026. Utah and several other high-tax states have also launched investigation programs. Proposed California legislation in 2026 would close the loophole at the statutory level.
Does having a Montana LLC affect my car insurance?
It can. If your vehicle is titled through an LLC but primarily kept in another state, your insurer needs to know the actual garaging location and use pattern. Specialty carriers like Hagerty are experienced with LLC-titled collector cars, but policies must accurately reflect how and where the vehicle is used.
Who are the best insurance carriers for exotic and collector cars?
For collector and classic vehicles, Hagerty is widely considered the industry leader for agreed value coverage. Pure Insurance and Chubb serve high-net-worth clients with broader collections. Berkeley Classics covers specialty and modified vehicles. MM Insurance works with all of these carriers.
What is agreed value insurance and why does it matter for collector cars?
Agreed value means you and the insurance company agree on the vehicle's value before a loss occurs. If the car is totaled, you receive that agreed amount without depreciation or negotiation. For irreplaceable vehicles, this is far superior to standard actual cash value policies.
How do I get my collector car collection properly insured in Wisconsin?
Contact MM Insurance at (262) 754-4736. We work with Hagerty, Pure, Chubb, and Berkeley Classics to structure coverage that matches the true value of your collection, your storage situation, and your usage patterns.
