Montana LLC structure and cost: no sales tax, the vehicle loophole, and no privacy

Montana has no state sales tax, and that single fact created its most famous and most-searched structure: the Montana LLC that owns and registers vehicles. Buy a $200,000 RV through a Montana LLC and there is no Montana sales tax on the purchase. That is the pitch, and whether it is legitimate or a crime depends entirely on where the vehicle actually lives.

Montana is the mirror image of New Mexico on privacy. New Mexico is cheap and genuinely private and weak on protection. Montana is cheap and genuinely not private, and its draw is the tax angle rather than anonymity.

Montana’s advantage is no sales tax, not privacy, and the vehicle structure it enables is legal only where the vehicle is truly Montana-connected.

Where the entity actually lives

A Montana LLC has a birthplace and a residence, and the where your LLC lives doctrine decides which controls what. That doctrine is not academic for Montana. It is the exact line between the legitimate vehicle LLC and the illegal one, because the entity sits in Montana while the vehicle is used wherever the owner is, and tax follows use.

The vehicle LLC, honestly

This is the reason many people find Montana, so it deserves a straight answer rather than a pitch or a scold.

For a Montana resident registering a Montana vehicle, the Montana LLC is ordinary. For an out-of-state owner, it is use-tax evasion that home states actively pursue.

The mechanism is real: Montana charges no sales tax, so a vehicle purchased and registered through a Montana LLC pays no Montana sales tax, and Montana does not require the owner to live in the state to form the company. If you live in Montana and the vehicle is garaged and driven in Montana, that is simply how Montana works, and it is fine.

The problem is the version sold to non-residents. If you live in California, Washington, or any state with a sales or use tax, garage the vehicle at your home, and drive it there, your home state’s use tax applies regardless of the Montana plate. Forming a Montana LLC to dodge it is use-tax evasion, not avoidance, and several states run enforcement programs aimed squarely at Montana-plated luxury vehicles and RVs seen in residential driveways. The exposure is back tax, penalties, interest, and in aggravated cases criminal charges. The registered LLC does not change where the vehicle lives, and where it lives is where the tax is owed.

The honest advice is narrow. If the Montana connection is genuine, the structure is genuine. If the only reason for the Montana LLC is to put a Montana plate on a car that lives somewhere else, it is the kind of plan that looks clever until the assessor’s letter arrives, and it is not something this site recommends.

No sales tax, for real businesses too

Beyond the vehicle case, the absence of a sales tax is a genuine operating advantage for a business actually located in Montana, since it removes the collection and remittance burden that consumes real time in sales-tax states. Montana has a flat personal income tax reaching 5.9%, no franchise tax, and income from a pass-through LLC flows to the members. There is no privilege tax on the entity for existing, which keeps the ongoing cost low, as the filing page details.

Series LLCs

Montana permits series, and prices them per member.

Montana allows series LLCs and charges $50 for each series member named in the Articles.

The series LLC page covers the general case against the structure: the internal walls rest on statutes with almost no case law, the bankruptcy treatment is unresolved nationally, the federal tax answer was never finalized, and the bookkeeping burden of ten series equals ten companies. Montana adds the per-series fee, which makes the cost explicit rather than hidden. None of the underlying risks change because Montana is inexpensive.

Privacy is weak

Here Montana and New Mexico part ways completely.

Montana lists members or managers on the annual report, so it is not an anonymity state.

Montana requires member or manager disclosure on its annual report, which puts the people running the company on a public filing that refreshes every year. An owner choosing Montana for privacy has misread the state; the reasons to choose Montana are cost and the absence of a sales tax, not name-off-the-record anonymity. The anonymous LLC page covers the states, including New Mexico, where privacy is a designed feature. Montana is not one of them.

Montana is also commonly listed among the states with no real estate transfer tax, which if correct is a clean advantage when moving property into an entity; confirm it against current Montana sources before relying on it.

The bottom line

Montana has no state sales tax, which is its genuine structural advantage and the basis for the vehicle LLC.

The vehicle LLC is legitimate for a Montana resident with a Montana vehicle and is use-tax evasion when the vehicle lives in another state.

Home states actively pursue Montana-plated vehicles garaged elsewhere, with exposure including back tax, penalties, and in some cases criminal charges.

Montana permits series LLCs at $50 per series member, with the same untested-walls risk as every series state.

Montana discloses members or managers on the annual report, so it offers no meaningful privacy, unlike New Mexico.

Montana likely has no real estate transfer tax, which is worth confirming before moving property into an entity.

What this page does not cover

This page is about what the entity costs and what it can be. How creditors reach you, including the foreclosable charging order, is on the protection page. The equal-shares default and the fiduciary rules are on the governance page. The $35 formation fee and the waived annual report are on the filing page.
