Montana

No state sales tax, no use tax, modest LLC fees, and a permissive vehicle and aircraft registration regime. The Montana-LLC structure has become the canonical pattern for U.S.-titled high-value vehicles and small aircraft. The structure works on paper everywhere and on substance only where the substance is real.

Why this jurisdiction matters

Montana imposes no state-level sales or use tax. A vehicle or aircraft titled in Montana incurs no Montana sales tax at acquisition and is subject to relatively modest annual registration fees. Combined with Montana's permissive LLC formation regime, the state has emerged as the preferred U.S. titling jurisdiction for high-value motor vehicles, recreational vehicles, and small aircraft owned by residents of high-tax states.

The relevant tax regime

• No state sales or use tax. Montana imposes no general state sales or use tax under MCA Title 15. Selective excises (lodging, rental car) exist but do not reach private vehicle or aircraft purchases.
• State income tax. Top marginal rate of approximately 5.9%, applying to Montana-resident individuals. Non-resident Montana-LLC owners pay no Montana income tax on out-of-state income.
• Annual LLC fee. $35 annual reporting fee for Montana LLCs; entity formation fee approximately $35.
• Vehicle registration fees. Permanent registration available for vehicles 11 years and older; otherwise annual fees graduated by vehicle age and value.
• Aircraft registration. Montana has an aircraft registration regime separate from FAA registration.
• No state estate or inheritance tax.

Registration or residency mechanics

Form a Montana LLC through the Montana Secretary of State (or through a registered-agent service specializing in vehicle-titling). Appoint a Montana registered agent. Title the vehicle or aircraft in the LLC's name with Montana motor-vehicle or aviation registration. No physical presence by the owner in Montana is required.

Reporting and disclosure

Montana entity records are accessible through the Secretary of State; LLC members are not required to be publicly disclosed. CTA beneficial-ownership disclosure to FinCEN applies to Montana LLCs.

The substance question

The substance question is the central enforcement issue. Montana titling does not, by itself, make a Montana resident of a vehicle's beneficial owner. The user state — typically California, Massachusetts, Connecticut, Washington — applies its own use-tax statute to property "used or stored" in the state.

State enforcement uses:

• Automatic license plate readers (ALPR) to identify Montana-plated vehicles operating regularly in-state.
• FBO records for aircraft based at in-state airports.
• Insurance documentation and registration cross-references.
• Cooperating data from car dealers, marinas, and storage facilities.

California has been particularly aggressive in pursuing Montana-LLC vehicle owners; the state has obtained settlements in seven-figure ranges from individual cases. The substance question — whether the vehicle's principal use is in California — turns on the documented pattern of use.

Recent changes

Montana statutory framework has been stable. The CTA beneficial-ownership reporting obligation applies as of 2024. State-level enforcement in user states continues to scrutinize Montana-LLC patterns.

Common asset classes parked here

• Classic and exotic cars — The canonical use case. Substance defense is the central risk.
• Private aircraft — Particularly small aircraft and propeller aircraft; less common for large business jets given operational base requirements.
• Recreational vehicles and motorcoaches — Montana-LLC titling is the dominant pattern for high-end RVs.
