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. Two brackets: 4.7% and a top rate of 5.65% for 2026, falling to 5.4% from 2027 under HB 337 (2025). Non-resident owners of a passive vehicle-holding LLC have no Montana-source income from it.
• LLC fees. $35 filing fee for articles of organization; $20 annual report due by 15 April ($15 late penalty). The Secretary of State waived the on-time annual-report fee for 2026 and 2027.
• Vehicle registration fees. Permanent registration is available for light vehicles 11 years and older; otherwise annual fees are graduated by vehicle age. Light vehicles 10 years old or newer with an MSRP of $150,000 or more pay an additional $825 a year.
• Aircraft registration. Aircraft based in Montana must also be registered annually with the Montana Department of Transportation Aeronautics Division (MCA Title 67), in addition to 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. Since FinCEN’s March 2025 interim final rule, domestic LLCs and U.S. persons are exempt from Corporate Transparency Act beneficial-ownership reporting. Only entities formed abroad and registered to do business in a U.S. state still report.

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, Utah, Illinois, Massachusetts, Connecticut or Washington) applies its own use-tax statute to property “used or stored” in the state, and its own vehicle-registration law to residents’ vehicles.

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 active: it presumes that a vehicle brought into the state within 12 months of purchase was bought for use there (Rev. & Tax. Code §6248), and the DMV has pursued Montana-plated vehicles, including through criminal tax-evasion referrals. Utah enacted SB 52 in March 2025 to share insurance and registration data to identify residents with Montana-registered vehicles. Illinois tribunals have rejected Montana-LLC arrangements as shams. The substance question (whether the vehicle’s principal use is in the user state) turns on the documented pattern of use.

Recent changes

Montana remains without a sales tax. HB 337 (2025) cuts the top income-tax rate to 5.65% for 2026 and 5.4% for 2027. The CTA reporting obligation that began in 2024 no longer applies to domestic LLCs after FinCEN’s March 2025 interim final rule. User-state enforcement has intensified, notably Utah’s SB 52 (2025) and continuing California DMV investigations. Figures as of October 2026.

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.
