For many years, forming a Montana limited liability company to register expensive vehicles has been promoted as a simple way to reduce or eliminate sales and personal property taxes. Montana does not impose a general sales tax, and its personal property tax structure is often more favorable than that of other states. The concept appears straightforward: create an LLC in Montana, title the vehicle under that entity, and enjoy significant tax savings.
The simplicity, however, is misleading. As states increasingly look to recover or generate additional tax revenue, this strategy has become increasingly risky. Recent events demonstrate the seriousness of the potential consequences associated with relying on this supposed loophole.
How the Montana LLC Vehicle Strategy Is Supposed to Work
In early November 2025, YouTuber Cody Detwiler, publicly known as WhistlinDiesel, was arrested in Tennessee on two felony counts of tax evasion. Prosecutors allege Detwiler titled a $400,000 Ferrari F8 Tributo under a Montana LLC rather than registering it in Tennessee, ultimately avoiding approximately $30,000 in state sales tax. Although Montana allows out-of-state LLCs to register vehicles, the determining factor for tax liability in Tennessee, as for most states, is where the vehicle is primarily kept and operated.
Tax Avoidance vs. Tax Evasion: A Line That Matters
If the vehicle is housed and used in your home state – whether Missouri, Illinois, or nearly any other state – you are legally required to register there and pay the applicable taxes. Failure to comply elevates the issue from a tax dispute to a criminal matter, as the Detwiler case illustrates.
The legal boundary is commonly misunderstood. Tax avoidance is the lawful structuring of your affairs to minimize taxes owed. Tax evasion, on the other hand, involves hiding information, misrepresenting facts, or creating sham structures to circumvent taxes.
When an individual forms an LLC in a state without any true business activity or legitimate connection to that state and uses it solely to reduce or eliminate taxes elsewhere, authorities increasingly classify this conduct as illegal evasion rather than lawful avoidance. Several states, including Missouri, California, and Massachusetts, have pursued residents for back taxes, interest, and substantial penalties. Utah’s enforcement regime, for example, imposes back taxes plus a 100 percent penalty, effectively doubling the amount owed.
There are also collateral risks. Insurance companies may deny coverage for improperly titled vehicles or for misrepresentations regarding where the vehicle is primarily stored. In some circumstances, federal tax authorities may inquire into the legitimacy of the company structure.
The Real Penalties States Are Imposing
The financial appeal is obvious. Avoiding an eight percent sales tax on a $100,000 vehicle means saving $8,000. Avoiding tax on a $400,000 vehicle can exceed $30,000. Nevertheless, the potential penalties, legal fees, reputational harm, and criminal exposure far outweigh the temporary savings. State governments are now actively sharing information, using license plate recognition technologies, and targeting high-value vehicles for enforcement.
Additional Risks Beyond Back Taxes
Before organizing an LLC strictly for registering your vehicle, consider alternatives that keep you in full compliance with the law:
- Explore legitimate tax planning tools available in your home state, such as trade-in credits or favorable timing of the purchase.
- Avoid services that promise compliance for a flat fee while ignoring the laws of the state where the vehicle is actually used.
- Consult a tax attorney before creating any multi-state ownership structure.
What to Do Instead
The Montana LLC vehicle registration tactic is often marketed as a simple solution to sales tax, but in practice, it is a legal and financial hazard. The wiser course is to pursue strategies that comply with both state and federal law. When uncertainty exists, professional advice is essential.
