Montana LLC member liability is sharply limited by statute: as a member or manager, you are not personally responsible for the company’s debts, contracts, or lawsuits simply because of your ownership or role.1Montana State Legislature. Montana Code 35-8-304 – Liability of Members, Managers, and Series of Members to Third Parties That default protection is strong. It is not absolute. Personal guarantees, your own wrongful acts, unlawful distributions, unpaid unemployment taxes, voluntary liability clauses in the articles of organization, and court-ordered veil-piercing can all put your personal assets back on the line.
What the Liability Shield Covers
Under Montana Code 35-8-304, a member or manager of a Montana LLC is not liable for the obligations of the company solely by reason of being a member or manager.1Montana State Legislature. Montana Code 35-8-304 – Liability of Members, Managers, and Series of Members to Third Parties The protection applies the same way whether the LLC is member-managed (run by all owners) or manager-managed (run by designated managers, who may or may not themselves be owners).2Montana Secretary of State Help Center. How Do I Know if My Business Is Member-Managed or Manager-Managed?
Montana is more forgiving than most states on one point in particular. The statute says that failing to observe formalities relating to the company’s powers and management is not, standing alone, a reason to impose personal liability on members or managers.1Montana State Legislature. Montana Code 35-8-304 – Liability of Members, Managers, and Series of Members to Third Parties Skipping a meeting or forgetting to document a resolution will not, by itself, cost you your protection. Sloppy records can still feed into a veil-piercing argument alongside other facts, but they cannot do the work alone.
When Members Become Personally Liable
The exceptions to the shield fall into a few recurring patterns. Some are statutory; some come from court doctrine; some you walk into voluntarily.
Personal Guarantees
This is the most common way members end up personally on the hook. When a newer or smaller LLC applies for a loan, a credit line, or a commercial lease, the lender or landlord often requires a member to sign a personal guarantee. The guarantee is a separate promise, outside the LLC’s liability shield, that you personally will pay if the company does not. If the LLC defaults, the creditor can pursue your personal assets for the guaranteed amount. Nothing in Montana law prevents this; you give up the protection on purpose when you sign.
Your Own Wrongful Acts
The LLC shield blocks liability for the company’s obligations. It does not shield you from the consequences of your own conduct. Section 35-8-304 protects members from liability arising “solely by reason of being a member or manager,” not from personal torts, fraud, or other wrongful acts you personally commit.1Montana State Legislature. Montana Code 35-8-304 – Liability of Members, Managers, and Series of Members to Third Parties If you injure someone through your own negligence while doing company business, if you defraud a customer, or if you commit any other tort in the course of operating the LLC, you are personally liable for that conduct regardless of the entity structure. The LLC is a shield against vicarious liability, not a cloak of immunity.
Unlawful Distributions
Montana prohibits an LLC from making a distribution to members if, after the distribution, the company could not pay its debts as they come due in the ordinary course of business, or if the company’s total assets would be less than its total liabilities.3FindLaw. Montana Code 35-8-604 – Distribution Limitations Members or managers who vote for or assent to a distribution that violates those limits are personally liable to the company for the excess.4Montana State Legislature. Montana Code 35-8-605 – Liability Upon Wrongful Distribution
In a manager-managed LLC, even a passive member who did not vote on the distribution can be personally liable if they knew it was unlawful and accepted the money anyway. Their exposure is capped at the amount they received above what they were properly owed. Any claim for a wrongful distribution has to be brought within two years of the distribution date.4Montana State Legislature. Montana Code 35-8-605 – Liability Upon Wrongful Distribution
Unpaid Unemployment Insurance Taxes
Many members do not realize that Montana’s unemployment insurance statute carves out a specific exception to the general LLC shield. If an LLC is treated as a partnership for unemployment insurance purposes, liability for unpaid unemployment taxes, penalties, and interest extends jointly and severally to each member and each manager.5Montana State Legislature. Montana Code 39-51-1105 – Liability for Taxes, Penalties, and Interest Owed The general LLC liability statute itself cross-references this exception.1Montana State Legislature. Montana Code 35-8-304 – Liability of Members, Managers, and Series of Members to Third Parties Joint and several liability means the state can collect the entire unpaid amount from any single member, not just that member’s proportional share.
Voluntary Liability in the Articles of Organization
The articles of organization can voluntarily make all or specific members personally liable for the company’s debts. This requires the provision to appear in the articles and the named member to consent in writing.1Montana State Legislature. Montana Code 35-8-304 – Liability of Members, Managers, and Series of Members to Third Parties This is uncommon in practice, but if you are joining an existing LLC, read the articles carefully before you sign on. The default shield can be contracted away.
Piercing the Veil
Montana courts can set aside the LLC’s separate legal existence and reach members personally under a two-part test. First, the LLC must be shown to be an alter ego or instrumentality of the member. Second, there must be substantial evidence that the LLC was used as a cover to defeat public convenience, justify a wrong, or commit fraud. Both prongs have to be satisfied. Courts weigh roughly 14 factors on the first prong, looking at things like how tightly the member controlled company assets, whether personal and business finances were mixed together, how the LLC held itself out to third parties, and whether the company was adequately funded.
The statute’s protection on formalities helps here: skipped meetings and informal management will not pierce the veil by themselves.1Montana State Legislature. Montana Code 35-8-304 – Liability of Members, Managers, and Series of Members to Third Parties But mixing personal and business bank accounts, paying personal expenses out of the LLC, and running the company with no real capital are the kinds of behavior that let a creditor stitch together a veil-piercing case even if no single fact wins it.
Liability to the Company and Other Members
Even where no outside creditor is involved, members and managers can create personal liability by breaching duties they owe inside the company. Montana imposes two fiduciary duties on members who participate in managing the LLC, and on all managers in a manager-managed company: the duty of loyalty and the duty of care.6FindLaw. Montana Code 35-8-310 – Standards of Conduct for Members and Managers
The duty of loyalty bars you from pocketing company profits or property, dealing with the company when you have a conflicting personal interest, or competing with the company while it is still operating. The duty of care is narrower: you only breach it through gross negligence, reckless conduct, intentional misconduct, or a knowing violation of law.6FindLaw. Montana Code 35-8-310 – Standards of Conduct for Members and Managers Ordinary business mistakes, even poor ones, do not reach that threshold. Both duties ride on top of a general obligation to act in good faith and deal fairly with the other members.
In a manager-managed LLC, passive members who do not exercise managerial authority owe no fiduciary duties to the company or the other members just because they hold an interest.6FindLaw. Montana Code 35-8-310 – Standards of Conduct for Members and Managers The moment a member starts exercising management rights under the operating agreement, though, the same duties attach to the extent of that authority.
An operating agreement can tailor these duties, but it cannot eliminate the duty of loyalty, unreasonably reduce the duty of care, or eliminate the obligation of good faith and fair dealing.7Montana State Legislature. Montana Code 35-8-109 – Effect of Operating Agreement, Nonwaivable Provisions It can identify specific categories of activity that will not be treated as disloyal (so long as the categories are not unreasonable) and set standards for measuring good faith.
What a Personal Creditor Can Reach
One point worth clearing up, because members often assume the worst: if you personally are sued and lose on an unrelated debt, the creditor cannot seize your membership interest, force the LLC to liquidate, or step into your management role. Montana makes a charging order the exclusive remedy for a judgment creditor of a member.8Montana State Legislature. Montana Code 35-8-705 – Rights of Judgment Creditor
A charging order acts as a lien on the member’s distributional interest and redirects any distributions the LLC would otherwise pay to the member. A court can order foreclosure on that lien, but the buyer at a foreclosure sale takes only the rights of a transferee: distributions when they come, with no vote and no management role. The interest can be redeemed before foreclosure by the debtor-member, by other members using their own property, or with company property if the operating agreement allows.8Montana State Legislature. Montana Code 35-8-705 – Rights of Judgment Creditor The exclusivity of this remedy is what insulates the business itself from the personal financial troubles of any one owner.
Keeping the Shield Intact
The liability shield depends on the LLC continuing to exist. Montana’s Secretary of State can administratively dissolve your LLC if you fail to file your annual report within 140 days of the deadline, fail to maintain a registered agent in the state for 60 days, fail to pay required fees, obtained your certificate of existence through fraud, or exceeded the authority granted by law after written notice.9Montana State Legislature. Montana Code 35-8-209 – Administrative Dissolution, Rules
A dissolved LLC can be reinstated, and reinstatement relates back to the date of dissolution so that the company is treated as having existed continuously.10Montana State Legislature. Montana Code 35-8-912 – Reinstatement Following Administrative Dissolution Even so, operating during a gap in good standing creates real uncertainty about whether the shield applies to transactions in that window, and a creditor will have an argument that it does not. Montana makes the annual report easy to stay current on: filed before April 15, the fee is waived; filed after, it is $35.11Montana Secretary of State.
