Fleet managers face a registration decision on every vehicle purchase: pay your home state sales tax and register locally, pursue IRP apportioned registration, or use a Montana LLC structure. Each approach fits a different situation. This guide breaks down the real cost difference and tells you which strategy to use and when.
The Core Trade-Off at a Glance
| Factor | IRP Apportioned | Montana LLC |
|---|---|---|
| Sales Tax at Purchase | Paid in home state | Zero (Montana) |
| Annual Registration Fees | Apportioned across all states | Montana only (low flat fee) |
| Multi-State Operations | Full legal authority in all IRP member states | Montana plate, no IRP apportionment |
| Best For | Commercial trucks crossing state lines regularly | High-value personal and commercial vehicles |
| Complexity | Higher — mileage reporting per state | Lower — one LLC, one state, one renewal |
When IRP Is the Right Answer
IRP (International Registration Plan) is designed for commercial motor vehicles that operate in two or more member jurisdictions. If you run a trucking operation with tractors or semi-trucks crossing state lines, IRP is not optional — it is legally required for vehicles over 26,000 lbs GVWR operating commercially across state lines.
IRP registration fees are apportioned based on the percentage of miles you drive in each state. If 30% of your miles are in Texas, 30% in Oklahoma, 20% in Louisiana, and 20% in Arkansas, those states each get a proportional share of your registration fees. No single state charges the full fee.
The advantage: one registration credential covers all member states. You do not need separate plates or registrations for each state you operate in.
When Montana LLC Is the Right Answer
The Montana LLC strategy makes the most financial sense for vehicles that meet these criteria:
- High purchase price ($30,000 or more, where tax savings are significant)
- Not subject to commercial IRP requirements (GVWR under 26,000 lbs for commercial, or personal use)
- Registered in a state with a meaningful sales tax rate (California, Texas, Florida, New York, etc.)
This includes work trucks under 26,000 lbs GVWR, fleet vans, company cars, and any commercial vehicle used within a single state or that does not require IRP credentials.
Real Example: Fleet of 10 Company Trucks in California
A California-based contractor buys 10 F-250 Super Duty trucks at $65,000 each. California combined sales tax rate: 9.5%.
- California registration cost: $65,000 x 9.5% x 10 trucks = $61,750 in sales tax
- Montana LLC registration cost: $0 in sales tax + LLC and registration fees through MRS
The savings on a single fleet purchase at this scale are significant. Montana Registration Services handles all 10 LLCs and registrations as a batch order at wholesale pricing.

Contact a Fleet Advisor →Frequently Asked Questions
Does IRP registration eliminate Montana LLC as an option for trucks?
Not for all trucks. IRP is required for commercial vehicles over 26,000 lbs GVWR operating across state lines commercially. For pickups, vans, and light-duty work trucks under that threshold, Montana LLC registration is still an option regardless of how many states you operate in.
Can a Montana LLC hold multiple vehicles?
Yes. A single Montana LLC can own and register multiple vehicles. MRS typically recommends a separate LLC per vehicle for liability isolation, but the right structure depends on your situation. We discuss this during account setup.
How fast can MRS process a fleet order?
LLC formation for each unit happens within 24 hours of a complete order. Montana title and registration processing typically takes 10-14 business days per unit. MRS processes fleet orders in batches so all units move through the pipeline simultaneously, not sequentially.
Is MRS experience with IRP or just Montana registration?
Both. MRS advises on IRP apportioned registration for applicable vehicles and handles Montana LLC registration for the rest of a fleet. We are not a one-size-fits-all shop. Fleet clients get a customized strategy, not a standard order form.
