Why Montana Banks Require an Operating Agreement
When you open a business checking account for a single-member LLC in Montana, banks like First Interstate Bank, Wells Fargo, Glacier Bank, and Stockman Bank ask for your Operating Agreement for three key reasons: (1) to verify that your LLC’s legal name matches the name on your EIN letter from the IRS; (2) to confirm that you, as the sole member, have the authority to open accounts and sign for the company; and (3) to satisfy their Know Your Customer (KYC) and beneficial ownership documentation requirements under federal banking rules. Without an Operating Agreement, many branches will ask you to come back with one — or worse, open the account with missing documentation that delays transactions later.

How Montana Code Annotated Title 35, Chapter 8 Protects You
Montana single-member LLCs are governed by Montana Code Annotated Title 35, Chapter 8 (Montana Limited Liability Company Act). This statute gives your LLC a legal existence separate from you personally, which is the foundation of liability protection: business debts and lawsuits generally attach to the company, not to your personal assets.
An executed Operating Agreement strengthens that protection in two ways. First, it documents that you treat the LLC as a separate entity (separate finances, documented decisions, formal management structure) — which is exactly what courts look for when creditors try to “pierce the veil” and reach your personal assets. Second, it locks in the internal rules that govern the company under the statute, so there is never ambiguity about who owns or controls the business.
Montana Compliance Alert
Montana LLCs file an Annual Report with the Montana Secretary of State by April 15th each year, with a $15 fee. A Montana registered agent is required.
These obligations are administered by the Montana Secretary of State. The LLC formation filing fee is $70. Failing to stay in good standing can jeopardize the liability protection your Operating Agreement helps document.
Montana Single-Member LLC Operating Agreement FAQs
Does Montana require a single-member LLC to have an Operating Agreement?
No state, including Montana, legally mandates a written Operating Agreement for internal validity — but banks, lenders, and courts treat your LLC as far more credible when you have one. Under Montana Code Annotated Title 35, Chapter 8 (Montana Limited Liability Company Act), an Operating Agreement governs the internal affairs of the LLC, and financial institutions like First Interstate Bank, Wells Fargo, Glacier Bank, and Stockman Bank routinely ask for it when you open a business checking account so they can verify your EIN, ownership, and signing authority.
Do I need an Operating Agreement to open a business bank account in Montana?
Most banks in Montana, including First Interstate Bank, Wells Fargo, Glacier Bank, and Stockman Bank, will ask for your Operating Agreement (or a Certification of Formation) as part of their business account onboarding process. They use it to confirm that the person opening the account is authorized to act for the LLC and to match the LLC's legal name to its EIN. While technically a single-member LLC without an Operating Agreement can still open accounts, having one avoids delays, confusion, and re-visits to the branch.
Does Montana protect my LLC assets from my personal creditors?
Yes, in most cases. Under Mont. Code Ann. Section 35-8-1005, a charging order is the exclusive remedy for judgment creditors of a member, protecting single-member LLC owners in Montana. This means your personal judgment creditors generally cannot seize LLC assets directly or force a distribution — they are limited to distributions the LLC chooses to make. Note that this protection is strongest when the LLC is treated as a separate entity (separate bank account, documented records, and an executed Operating Agreement).
What are the annual requirements and fees for an LLC in Montana?
Montana LLCs file an Annual Report with the Montana Secretary of State by April 15th each year, with a $15 fee. A Montana registered agent is required. The state LLC filing fee is $70, paid to the Montana Secretary of State. Keeping your LLC in good standing — filings current and registered agent up to date — is essential to preserving the liability protection the Montana Code Annotated Title 35, Chapter 8 (Montana Limited Liability Company Act) provides.
