Registering an RV through a Montana LLC includes LLC and registration charges plus Montana's motorhome fees. The state allows permanent registration for eligible motorhomes at 11 model years, but it is not automatic. MPC's separate optional $99 service is offered only for vehicles strictly more than 15 model years old, subject to staff review.
RVs and motorhomes are the vehicles most often registered through a Montana LLC, for two reasons: Montana charges no sales tax on a purchase that can run well into six figures, and Montana offers permanent registration once a coach reaches 11 model years. The LLC is the titled owner, our Bozeman office is its registered agent, and the county treasurer registers the coach on Montana's motorhome fee schedule. See our Montana LLC RV registration page for the service overview; here is what each piece costs.
Why do RV owners use a Montana LLC?
- No sales tax. A $300,000 coach in a 7% state carries $21,000 in tax; through a Montana LLC it carries none.
- Permanent registration is a Montana option at 11 model years and older when actually issued, not an automatic result of age or the base service.
- No home base needed. Full-time travelers with no fixed state can still hold a valid registration, because the LLC's address is the registered agent's.
- One LLC can hold the coach, the tow car, and a trailer under a single $149 annual renewal.
What are Montana's motorhome registration fees by age?
Montana registers motor homes on a fee that declines with age, published by the Motor Vehicle Division under MCA 61-3-321. Age is the current year minus the model year.
| Coach age | Annual fee | Permanent option |
|---|---|---|
| Under 2 years | $282.50 | No |
| 2 to under 5 years | $224.25 | No |
| 5 to under 8 years | $132.50 | No |
| 8 to 10 years | $97.50 | No |
| 11 years and older | $97.50 | Yes, one-time $237.50 |
When does an RV qualify for permanent registration?
Montana's legal option begins at 11 model years and older; the listed state permanent fee is $237.50 for an eligible motorhome. That does not automatically replace an annual registration. MPC offers a separate optional $99 one-time service per selected vehicle only when it is strictly more than 15 model years old (2010 or earlier in 2026; 2011 or earlier in 2027), subject to staff review of the vehicle and plate before filing. Permanent registration, if issued, does not transfer on a sale. Our permanent registration guide explains the distinction.
What is the Montana luxury motorhome fee?
Montana charges an $800 annual luxury fee on motor homes with an MSRP over $300,000 that are 10 model years or newer, in addition to the age-based registration fee. It is assessed on MSRP, not on what you paid, so a two-year-old coach bought used for $250,000 with a $340,000 sticker still pays it. At 11 years it stops. The parallel fee for cars is $825 on an MSRP over $150,000.
Does county option tax apply to RVs?
In most counties, yes. Under MCA 61-3-537, 45 of Montana's 56 counties levy a county option tax of up to 0.7% of the vehicle's depreciated value each year; six counties (Big Horn, Deer Lodge, Flathead, Granite, Phillips, and Richland) do not. The figure depends on the filing county and the coach's depreciated value, and we quote it before you pay.
What about towables, fifth wheels, and tow vehicles?
Travel trailers and fifth wheels are registered as trailers, and Montana offers permanent trailer registration with a one-time fee based on weight, so most towables never renew. The tow vehicle is a light vehicle on the car schedule: $217 a year at 0 to 4 years, $87 at 5 to 10, $28 at 11 and older, with permanent registration available at 11 years. All of them can sit under the same LLC.
What does the whole RV package cost, with an example?
Take a 2019 diesel pusher with a $350,000 MSRP registered in 2026. The LLC is $199 plus the $35 state filing fee. Standard Registration at the $250,000-and-up bracket is $1,549. Montana charges $12 for the title, $12 for plates, and $132.50 for a coach in the 5-to-under-8-year band, plus the $800 luxury fee because the coach is under 11 years with an MSRP over $300,000, plus county option tax. Total in year one is roughly $2,700 plus the county figure, against about $24,500 of sales tax the same coach would carry in a 7% state. From year two the LLC costs $149 and the coach continues to renew annually unless permanent registration is separately requested and actually issued; turning 11 alone does not change it.

Related questions
Can a full-time RVer register in Montana with no home state?
Yes. The Montana LLC is the owner and the registered agent's Bozeman address is its address of record, so the registration does not depend on where you personally live. Full-time travelers commonly pair the LLC with a mail-forwarding service in the state they use for their driver's license.
Is Montana RV registration permanent?
It can be if permanent registration is requested and issued. Montana's legal option for eligible motorhomes begins at 11 model years, but MPC's separate optional $99 service is offered only for vehicles strictly more than 15 model years old, subject to staff review. A coach registered annually continues to renew regardless of age.
Does the luxury fee apply to a used RV?
Yes, if the coach is 10 model years or newer and its original MSRP was over $300,000. Montana assesses the $800 annual fee on the manufacturer's price, not the price you paid. At 11 model years the fee stops and permanent registration becomes available.
Can I register my truck and fifth wheel under the same LLC?
Yes. One Montana LLC can hold the truck, the fifth wheel, and the motorhome. The truck registers on the light-vehicle schedule, the fifth wheel as a trailer with a permanent option, and all of them share the same $149 annual registered agent renewal.
