Vehicle owners who register assets through Montana LLCs while primarily using or garaging them elsewhere face increasing state scrutiny and potential assessments for tax, registration fees, penalties, and interest.
The practice is commonly called the “Montana Loophole.” Montana has no general sales tax, so an out-of-state owner may form a Montana limited liability company and title a luxury vehicle, motorhome, aircraft, or collector car in the entity’s name. The intended benefit is to avoid sales or use tax and reduce registration or permitting costs in the owner’s home state.
States have long challenged the structure when the asset is mainly used, stored, or garaged outside Montana. In those circumstances, most states maintain that their use-tax and registration requirements still apply.
Expanded Enforcement Efforts
State authorities are using more sophisticated data and greater coordination to find noncompliant registrations. Their methods include:
- Data sharing among departments of revenue, motor-vehicle agencies, and law enforcement.
- Automated license-plate reader records that show where a vehicle is located and used.
- Toll, telematics, and GPS information.
- Insurance-database matching to identify the stated garaging location.
- Dealer audits and other compliance initiatives.
- Targeted enforcement projects and surveillance.
- Legislation intended to close perceived registration loopholes.
Together, these sources can show that a Montana-registered vehicle is actually subject to tax and registration in another jurisdiction.
State-Level Developments
Several states have adopted or proposed specific measures:
- California: The California Department of Tax and Fee Administration and the DMV have conducted hundreds of investigations using analytics and license-plate reader technology to identify vehicles located mainly in California but registered elsewhere.
- Georgia: Authorities use toll-tag records, insurance databases, and dealer audits to identify improper registrations.
- Illinois: Legislation permits the state to look through the LLC and hold an individual resident directly liable for unpaid vehicle taxes.
- Indiana: New legislation specifically addresses improper out-of-state vehicle registration, including Montana LLC structures.
- Missouri: Proposed legislation would prohibit residents from registering vehicles in another state to avoid Missouri tax, with possible fines and driver’s-license suspension.
- Utah: Expanded data sharing and enforcement authority permit penalties of up to 100% of the tax due, in addition to interest.
- Wyoming: The state presumes that out-of-state registration does not eliminate a resident’s Wyoming tax obligation when the vehicle is used in the state.
Financial Exposure and Risk Considerations
The potential exposure extends beyond the original sales or use tax. States may also assess registration fees, penalties, and interest. In some cases, the total liability can exceed the tax savings that motivated the structure.
Some states are also more willing to disregard the Montana LLC and assert that the individual owner, rather than the entity, owes the tax.
Proactive Planning Opportunities
A taxpayer using or considering a Montana LLC should evaluate the facts carefully. Risk is higher when the vehicle is:
- Primarily garaged or used outside Montana.
- Insured in another state.
- Routinely operated in the taxpayer’s state of residence.
Addressing the issue before an audit may create options that are unavailable later. Depending on the jurisdiction, a voluntary disclosure program, amended returns, or an ownership restructuring may reduce penalties and limit interest compared with waiting for an enforcement action.
