Montana LLC Cost for Rental Property: What You Actually Pay

The decision to hold Montana rental property inside an LLC is not purely about asset protection — it affects your financing options, tax structuring, and annual compliance obligations. Before making that decision, you need the actual numbers, not a general statement that "LLCs provide liability protection."

Montana's LLC costs are low relative to most states. Here is exactly what you will pay.

Formation Costs

Filing Articles of Organization online through the Montana Secretary of State's Business Filing Portal costs $35 for a domestic (in-state) LLC. Foreign LLCs — entities formed in another state that are registering to do business in Montana — pay $70 for a Certificate of Authority.

Expedited processing is available at extra cost. For 24-hour priority processing, the fee is an additional $20. For one-hour processing, it is an additional $100. Standard online filing turnaround is several business days. If you are in a time-sensitive acquisition, the expedited options exist but are rarely necessary for most investment scenarios.

Annual Reporting

Montana requires all LLCs to file an annual report to maintain active standing. The standard filing fee is $20, but the Montana Secretary of State waives this fee for on-time filings submitted online by the April 15 deadline. File on time online, and your annual state compliance cost is $0 in state fees.

Miss the deadline, and the total charge becomes $35 — a $15 late penalty on top of the $20 base fee. Continue to miss filings, and the Secretary of State can administratively dissolve the entity. Reinstatement requires paying all back fees and penalties.

Registered Agent

Every Montana LLC must maintain a registered agent with a physical Montana street address to receive legal service of process. A P.O. Box does not qualify. Montana residents who are active in the state can serve as their own registered agent at no cost. Out-of-state investors — which describes the majority of people forming Montana LLCs for investment property — cannot serve as their own registered agent without maintaining a physical address in the state.

Commercial registered agent services fill this gap. Market rates for Montana registered agent service range from $50 to $300 per year. The lower end of that range represents basic registered agent service: receive service of process, forward it to you. The higher end typically includes additional compliance notifications and document storage. For a single-property holding company, the basic tier is sufficient.

Total Annual Cost Summary

For a domestic Montana LLC filing on time each year and using a mid-range registered agent service, your ongoing annual cost runs $100 to $200. Formation is a one-time $35 expense. There is no franchise tax, no minimum business tax, and no state corporate income tax imposed on pass-through LLC structures.

What the LLC Does and Does Not Do

A Montana LLC provides a legal separation between you as an individual and your property-holding entity. If a tenant is injured on the property and sues, a properly maintained LLC creates a barrier that limits the claim to assets held within the entity — not your personal accounts, other properties, or retirement funds. That protection holds as long as you maintain the entity properly: separate bank accounts, no commingling of funds, documented operating decisions, and consistent use of the LLC name on leases and contracts.

What the LLC does not do is provide financing flexibility. Most conventional lenders and DSCR lenders will finance properties in single-member LLCs, but some require the loan to be held in your personal name with the property later transferred to the LLC via deed. That transfer can trigger a due-on-sale clause in the loan documents, depending on the lender. Fannie Mae and Freddie Mac loans explicitly prohibit this transfer without lender consent. If you are using conventional conforming financing, discuss the entity strategy with your lender before closing.

The Financing Trade-Off

For investors using DSCR loans — non-qualified mortgages underwritten on the cash flow of the property rather than personal income — many lenders already structure the loan in the LLC's name. This aligns the asset protection structure with the financing structure from day one and avoids the transfer issue entirely.

For investors using conventional conforming loans (Fannie/Freddie), the standard approach is to close in personal name and either accept the exposure during the financing period or work with a lender that explicitly permits post-close LLC transfers. Getting this wrong — transferring without lender notice on a due-on-sale clause — creates a technical default.

When Multiple Properties Change the Calculation

Single-property investors sometimes question whether a $35 filing fee and $150 per year in registered agent costs is worth it for one small rental. For a single property financed with DSCR and generating modest returns, the protection math may not be compelling.

For investors building a multi-property portfolio, the calculation shifts. At two or more properties, the standard structure is separate LLCs for each property — one lawsuit against one property cannot reach assets held in a different entity. The cost scales with the number of entities, but the structure reflects actual risk management rather than theoretical asset protection.

Montana's low formation costs make this multi-entity approach accessible. A three-property portfolio might require three LLCs, three registered agent contracts, and three annual report filings — total annual cost in the $300 to $600 range for the entire holding structure. In most other states, that cost would be two to three times higher.

Operating in Montana vs. Forming in Another State

Some investors form LLCs in Wyoming or Nevada for their purported charging order protections, then register those entities as foreign LLCs in Montana to hold Montana property. This approach adds complexity — you pay formation fees in two states and registered agent fees in two states — without clearly superior asset protection for real estate held in Montana, which is already subject to Montana law regardless of where the entity is formed.

For most investors holding Montana rental property, a domestic Montana LLC is the cleaner, lower-cost, and operationally simpler structure. If your situation involves multi-state portfolios, complex estate planning, or significant liability exposure from other business activities, consult a Montana-licensed attorney before deciding on entity structure.
