Single-member Montana LLC

A single-member LLC still benefits from an operating agreement. It helps with banking, contracts, bookkeeping, and documenting the separation between the owner and company.

Multi-member Montana LLC

Multi-member LLCs need more detail. Put voting, distributions, buyouts, member exits, tax responsibilities, and management authority in writing before money or disputes create pressure.

Operating agreement FAQ

Do I file the operating agreement with Montana?

Usually no. Keep it with company records unless a specific transaction, bank, tax professional, court, or agency asks for it.

Is the operating agreement the same as Articles of Organization?

No. Articles form the LLC. The operating agreement governs internal rules.

Should it mention annual reports and licenses?

Yes. It is practical to assign responsibility for annual reports, DOR accounts, unemployment, eStop licenses, local licenses, and company records.
