Montana permits permanent registration for eligible light vehicles and motorhomes at 11 model years and older, but an annual registration does not change automatically. MPC's optional, separate $99 service is available only for a vehicle strictly more than 15 model years old (2010 or earlier in 2026; 2011 or earlier in 2027), per selected vehicle, with staff review of the vehicle and plate before filing.
Montana permanent vehicle registration replaces the yearly trip to the county treasurer with a single one-time fee, and owners often call the result forever plates. It is written into MCA 61-3-321 and administered by the county treasurers and the Motor Vehicle Division, and it is one of the two reasons out-of-state owners register through a Montana LLC; the other is that Montana charges no sales tax. Here is which vehicles qualify, what it costs, and how it behaves when the vehicle is owned by an LLC.
Which vehicles qualify for permanent registration in Montana?
Montana's permanent-registration option for eligible light vehicles (cars, SUVs, and pickups) and motor homes starts at 11 model years, per the Motor Vehicle Division. This state eligibility is not MPC's sales threshold and is not an automatic switch. Montana generally requires permanent trailer registration regardless of age, and street-legal motorcycles receive permanent registration at any age; other classifications have their own rules. Staff confirms each vehicle and plate before filing. MPC offers its optional $99 service only for vehicles strictly more than 15 model years old, regardless of type, subject to that review. On a trailer or motorcycle already registered permanently by state rule, it pays for separate preparation and coordination, not an additional permanent-registration benefit; it may provide no additional registration benefit.
| Vehicle class | Eligible when | One-time fee |
|---|---|---|
| Light vehicle (car, SUV, pickup) | 11 model years and older | $87.50 |
| Motor home | 11 model years and older | $237.50 |
| Trailer, travel trailer, fifth wheel | Generally any age; staff review exceptions | Based on class/weight |
| Motorcycle | Street-legal motorcycles: permanent at any age | Per Montana schedule |
| Boat or personal watercraft | Older units; confirmed per vehicle | Per Montana schedule |
What does permanent registration cost?
Montana lists one-time permanent-registration fees of $87.50 for an eligible light vehicle and $237.50 for an eligible motorhome; these are state figures, not MPC's price. MPC's optional service is an additional, one-time $99 per selected vehicle on top of the registration quote, not a government fee. It is offered only for vehicles strictly more than 15 model years old, with staff review; 2011 is too new in 2026, while 2010 qualifies for an offer. In 2027, 2011 qualifies for an offer but 2012 does not. Neither the state age threshold nor an MPC offer guarantees that permanent registration will be issued. The cost guide discusses fees.
Does permanent registration survive a sale or a title change?
No. Permanent registration attaches to the owner and the vehicle together; when the vehicle is sold, the new owner registers it again and pays the fee again. This is where LLC ownership matters. The LLC is the owner of record, so a change in who holds the LLC's membership interest does not change the titled owner, and the permanent registration stays in place. Sell the vehicle out of the LLC and the buyer starts over.
How does permanent registration work with a Montana LLC?
The LLC holds the title and the county issues the applicable registration. If permanent plates are requested and issued after staff review, they have no annual vehicle-registration renewal; otherwise the vehicle may continue to renew annually even after 11 model years. The LLC's annual report by April 15 and applicable taxes are separate obligations.
Is there a permanent option for newer light vehicles?
For a light vehicle under 11 model years, no: its state registration fee is $217 a year for the first four years and $87 a year from years five to ten. An eligible light vehicle can choose permanent registration at 11 model years, but the change is not automatic. Trailers and street-legal motorcycles generally register permanently regardless of age under separate state rules. Motorhomes have their own age-based schedule; the RV cost guide explains it.
What about insurance and inspections?
Montana has no periodic safety or emissions inspection for registered vehicles, so a permanently registered vehicle never returns to the county. Insurance is still required and is written with the LLC as the named insured at the vehicle's actual garaging address. Keep the registration receipt in the vehicle; there is no yearly sticker to replace.
If permanent registration is actually issued for an eligible vehicle, it generally avoids annual vehicle-registration renewal while the same owner keeps it. It is not automatic at 11 model years or included just because the base registration was purchased.

Permanent plates do not change where a vehicle is used, so a vehicle kept at your home may still face home-state use tax; ask a tax professional. The step-by-step RV guide shows the filing and pricing lists our separate fees. The quote builder allows a qualifying-age vehicle to request the optional MPC service; final vehicle and plate eligibility requires staff review before filing.
Related questions
Does Montana permanent registration ever expire?
No. Once a light vehicle or motor home 11 model years and older is registered permanently, the registration stays valid for as long as the same owner keeps the vehicle. It ends only when the vehicle is sold or otherwise changes titled owner, at which point the new owner registers it again.
Can I get permanent registration on a new car?
Montana's permanent option for eligible light vehicles and motorhomes begins at 11 model years. That is a state rule, not MPC's service threshold: our optional $99 service requires a vehicle strictly more than 15 model years old and staff review. A registration does not become permanent automatically on reaching either age. Other vehicle types have separate rules.
Do I still owe the annual report with permanent plates?
Yes. Permanent registration covers the vehicle; the annual report covers the LLC that owns it. The report is due to the Montana Secretary of State by April 15 each year, and our $149 Registered Agent Renewal files it. Miss it and the LLC can be dissolved, which puts the registration at risk.
Does permanent registration transfer to a buyer?
No. It attaches to the owner and vehicle together, so a buyer must register the vehicle again and pay the fee again. When an LLC owns the vehicle, changing who owns the LLC does not change the titled owner, so the permanent registration stays in place until the vehicle itself leaves the LLC.
Does Montana have permanent license plates?
Yes. Montana offers permanent registration for eligible light vehicles and motorhomes at 11 model years and older; other vehicle classes have their own rules. This is legal eligibility, not automatic issuance. MPC's separate optional service costs $99 per selected vehicle and is offered only when the vehicle is strictly more than 15 model years old, subject to staff review.
