State targets cars plated in Montana to avoid sales tax: BTAX

At least four states are intensifying efforts to address tax avoidance strategies involving Montana vehicle registrations, where non-residents exploit the state’s lack of a sales tax and low registration fees to minimize obligations in their home states according to a 2026 analysis. The practice, which involves forming Montana limited liability companies (LLCs) to register high-value vehicles, has prompted legislative and enforcement responses in Indiana, Missouri, Georgia, and Utah. These states aim to recoup lost revenue from sales taxes and vehicle registration fees, estimated in the billions annually, by closing loopholes that allow out-of-state residents to operate vehicles registered in Montana as detailed in the report.

A 2025 Bloomberg Tax analysis identified over 600,000 vehicles registered in Montana but primarily operated elsewhere, a trend driven by both luxury vehicle owners and mid-tier brands like Ford and Toyota according to the analysis. While Montana’s vehicle registration system permits non-residents to register vehicles for as little as $35 annually—compared to significantly higher fees in other states—critics argue this creates an unfair advantage and erodes state tax bases.

Legislative measures in Indiana and Missouri focus on verifying residency and usage patterns to prevent abuse, while Georgia and Utah have implemented enforcement mechanisms under laws passed in 2025 as reported. The crackdown reflects broader concerns about states losing revenue from tax strategies enabled by jurisdictional disparities, with officials emphasizing the need to align registration practices with actual vehicle usage.
