🏁 Why Vehicle Owners Choose These States

Many people choose Montana or South Dakota for out-of-state vehicle registration because:

They want to minimize or eliminate sales tax (Montana)
They need to avoid high registration or luxury taxes in their home state
They own unique, custom, or classic vehicles
They prefer privacy through LLC ownership
They want to solve title problems, like missing or lost titles (Montana)
They want fast registration via 24-hour temporary tags (Montana)
They want permanent plates for older vehicles (Montana, 10+ years)
They live full-time on the road (RVs, trailers, nomads)
And — importantly — neither state generally requires emissions or smog testing, simplifying registration for high-performance or older builds

🔍 Montana LLC Vehicle Registration

Best For:

Exotic & supercars (Lamborghini, McLaren, Ferrari, GT-R, etc.)
High-value RVs, overland builds, trailers
Owners of multiple vehicles who want to consolidate under one LLC
No-title or lost-title projects, classic vehicles, or out-of-state trailer purchases
Vehicles older than 10 years that qualify for permanent plates

Key Advantages

No sales tax — potentially huge savings
Temporary tags in 24 hours — road access fast
Permanent plates for vehicles 10+ years old — avoid yearly renewals
Custom license plates — perfect for exotic, classic, or branded vehicles
LLC ownership — keeps your personal name off title
Title solutions for no-title or missing-title vehicles
No emissions/smog testing required in most cases

Important Considerations

Financed vehicles require explicit lender approval to title under LLC
If you already paid sales tax, savings from Montana may be limited
LLC setup and annual maintenance are required
Must comply with your home state’s legal obligations if the vehicle is primarily garaged there

🔍 South Dakota Vehicle Registration

Best For:

RV and trailer owners traveling full time
Vehicle owners with financed liens who want a smooth title transfer
People looking for a quick, non-LLC title route
Owners who want to avoid emissions testing hassles

Key Advantages

No residency requirement — you can register remotely
Easier handling of financed vehicles without needing to change the lien structure
Fast and simple paperwork
Ideal for travelers using mail-forwarding services
No emissions/smog testing — a major plus for high-performance or older vehicles

Considerations

Typically subject to ~5% vehicle excise tax
Title usually lists your name — less privacy than an LLC
Not as tax-efficient for high-value vehicles
Less custom plate / branding potential compared to Montana
No permanent plate option

💡 Which Option Is Likely Best for You

Scenario	Recommended State
Bought a supercar or RV, and haven’t paid sales tax	✅ Montana LLC — maximum tax benefit + privacy
Vehicle is financed but your bank won’t allow LLC titling	✅ South Dakota — safer, simpler title transfer
Full-time RVer or nomad	✅ South Dakota — minimal setup, no LLC required
You want a custom plate, permanent plate, or an LLC for multiple vehicles	✅ Montana LLC — more flexibility, more privacy
You’re dealing with a missing or no title situation	✅ Montana — offers title solutions for many non‑titled vehicles
You already paid sales tax at purchase	✅ Consider the cost/benefit carefully — SD may be more practical

📌 Compliance & Insurance Tips

To stay fully compliant when registering out of state:

Tell your insurance company where the vehicle is actually garaged
Keep documentation proving legal and physical ownership
Ensure any lender agreement approval is in writing before doing an LLC title transfer
Stay up to date on your home state’s rules - some states may require registration locally if the vehicle spends 6+ months out of the year there, but not if it doesn't. Understanding this can help avoid any self incrimination or potential issues.

EZ-Plates can help you navigate all of that.
