South Carolina Limited Partnership FAQ

A limited partnership is one of the older business structures, and it exists to solve a specific problem: how do you let some people put money into a venture without exposing them to its liabilities, while someone else actually runs it? South Carolina answers that with its limited partnership statute under Title 33 of the South Carolina Code.

What exactly is a limited partnership?

An LP has at least one general partner and at least one limited partner. The general partner manages the business and bears personal liability for its obligations. The limited partner invests, shares in profits, and is shielded from liability beyond their investment — provided they stay out of management. That split is the defining feature of the structure.

How is an LP different from an LLC or a general partnership?

In a general partnership, every partner manages and every partner is personally liable — there's no liability shield at all. In an LLC, all members typically get liability protection and can all participate in management. An LP sits in between with a deliberate division: active manager on the hook, passive investors protected. You pick an LP specifically when you want that division rather than everyone sharing both control and protection.

Do I need more than one person to form an LP?

Yes. By definition an LP requires at least one general partner and at least one limited partner, so a single individual can't be both roles of a real LP alone. That said, the general partner can be an entity — many partnerships make an LLC the general partner — which is a common way to structure who holds control and liability.

Getting an LP onto South Carolina's records is a filing exercise. The rules aren't complicated, but they're specific.

What document creates a South Carolina LP?

The Certificate of Limited Partnership, filed with the South Carolina Secretary of State. The partnership legally exists once the state accepts it. The certificate names the partnership, its registered office, its registered agent, and each general partner. Limited partners are not listed on this public filing.

Where and how do I file?

Through the Secretary of State's business filing portal at businessfilings.sc.gov, or by mail. Online is faster — typically one to two business days versus up to about two weeks for mail.

What has to be in the partnership's name?

The name must include a limited partnership designator such as "Limited Partnership" or "L.P.", and it must be distinguishable from other names on file with the Secretary of State. Check availability first using the state's business name search at sos.sc.gov.

Do the partners have to live in South Carolina?

No. General and limited partners face no residency rule. What South Carolina does insist on within the state is a registered agent holding a physical street address there.

Once the LP exists, the recurring obligations are lighter than in many states — but "lighter" isn't "none."

Does my LP need a registered agent?

Yes. Every South Carolina LP must name a registered agent in its certificate and maintain one for the life of the entity. The agent needs a physical South Carolina street address and must be available during business hours to receive legal documents. You can serve yourself, name another individual, or use a commercial service.

Is there an annual report for LPs?

South Carolina does not run a general Secretary of State annual report regime for limited partnerships the way many states do. That's a real difference — there isn't a routine yearly Secretary of State report to file for a standard LP. This does not eliminate your tax obligations, which run through the IRS and the South Carolina Department of Revenue on their own schedules. Confirm your specific filings with a CPA.

What if my general partners or agent change?

If your registered agent changes, file a change of registered agent with the Secretary of State. If a general partner joins or leaves, you may need to amend the Certificate of Limited Partnership, since general partners are on the public record. Keep the record current so service of process always reaches the right place.

The economics of an LP live in two places: the federal tax system and your private partnership agreement.

How is an LP taxed?

By default, an LP is a federal pass-through entity. It files an informational partnership return (Form 1065) and issues a Schedule K-1 to each partner. The partners report their shares on their own returns; the LP pays no federal income tax at the entity level. South Carolina taxes partnership income at the partner level in a comparable way, and nonresident partners may have additional obligations. Your CPA should map this to your situation.

Do I need a limited partnership agreement?

You're not required to file one with the state, but you should absolutely have one. Without a written agreement, the statute's default rules govern how profits are split, how decisions get made, and what happens when a partner exits — and those defaults rarely match what the partners intended. The agreement is where capital contributions, profit allocations, preferred returns, general-partner authority, and limited-partner rights are all spelled out.

Can I add partners later or convert the LP?

Yes. New partners can be admitted according to the terms of your partnership agreement, and interests can be transferred subject to the agreement's rules. Structural changes — converting to another entity type or reorganizing — are possible but have tax and legal consequences, so involve an attorney and CPA before you make them.

You can file everything yourself. Plenty of people do. What a service buys you is time and the confidence that the state-facing paperwork is right.

What does Mainstay Filing do?

We prepare and file your Certificate of Limited Partnership with the South Carolina Secretary of State and provide registered agent service, so a professional South Carolina address goes on the public record instead of a partner's home address. We return the accepted filing once the state processes it, and we receive and forward legal mail as your agent going forward.

What does Mainstay Filing not do?

We're not a law firm or an accounting firm. We don't draft the economic terms of your partnership agreement, advise on splitting profits between general and limited partners, or provide tax planning. Those belong with an attorney and a CPA. Our job is the filing and the registered agent role — done correctly, on time, without you having to learn the Secretary of State's system.
