South Dakota LLC Operating Agreement Laws and Requirements

An LLC operating agreement in South Dakota defines how your limited liability company is managed, how profits are distributed among members, and what happens if a member leaves or the company dissolves. While not always legally mandated, an LLC operating agreement is practically essential in South Dakota for maintaining limited liability protection, opening business bank accounts, and establishing the governance framework for your company.

Without an operating agreement, South Dakota's default LLC statutes govern your business — and these default rules rarely align with what members actually intend. For example, default rules may require equal profit-sharing regardless of capital contributions, allow any member to bind the company, or impose restrictive dissolution triggers. A properly drafted operating agreement overrides these defaults. Use our LLC operating agreement generator to create a South Dakota-compliant agreement.

South Dakota LLC Operating Agreement FAQ

Does South Dakota require an LLC operating agreement?
While most states do not legally require an operating agreement, it is practically essential in South Dakota for maintaining liability protection, opening business bank accounts, and establishing clear governance. Banks typically require a copy before opening a business account, and courts look for one when determining whether the LLC's limited liability should be upheld.
What should a South Dakota LLC operating agreement include?
A South Dakota LLC operating agreement should include: member names and ownership percentages, capital contributions, profit and loss distribution, management structure (member-managed vs. manager-managed), voting rights and procedures, transfer restrictions, dissolution procedures, and dispute resolution. Our LLC operating agreement generator covers all required provisions for South Dakota.
Does a South Dakota LLC operating agreement need to be filed with the state?
No. An LLC operating agreement is an internal governance document and is not filed with South Dakota's Secretary of State. You must keep it with your company records. The document you file with the state is the Articles/Certificate of Organization, which is separate from the operating agreement.
Can a single-member LLC in South Dakota operate without an operating agreement?
Technically, a single-member LLC can operate without one in most states, but this significantly weakens your liability protection. Without an operating agreement, courts may find that you and the LLC are indistinguishable ("piercing the corporate veil"), making your personal assets vulnerable to business liabilities. A single-member operating agreement takes minutes to create and provides essential legal protection.
What happens if a South Dakota LLC has no operating agreement?
Without an operating agreement, South Dakota's default LLC statute governs your business. Default rules often impose equal profit-sharing regardless of capital contributions, allow any member to bind the company, and may trigger dissolution if a member departs. These defaults rarely match what business owners intend. Create a custom agreement with our South Dakota LLC operating agreement generator.
