Assumed-Name (DBA) Registration Requirements in South Carolina

At a glance

Requirements one by one

Most businesses do not file a state DBA

South Carolina Business One Stop says it plainly: “The state of South Carolina does not register DBAs.” The Secretary of State's own FAQ likewise says the office “does not register DBA or trade names.” That is the rule for an ordinary sole proprietor, general partnership, corporation, or LLC using another name. There is no general state certificate, deadline, publication step, fee, term, renewal, or nonregistration penalty for those businesses.

The practical route is local. State guidance tells the business to start with the municipality or county where it will operate, obtain the applicable local business license, and ask the county clerk whether that jurisdiction has any additional DBA documentation. Those local rules and charges are separate and can vary; South Carolina has not converted them into a statewide registry.

Limited partnerships are the narrow exception

S.C. Code § 33-42-45 creates a specific state assumed-name system for limited partnerships. A domestic LP using a name other than the one on its certificate of limited partnership must file with the Secretary of State. The same applies to a foreign LP registered in South Carolina when it uses a name other than the one on its certificate of registration.

The certificate states the LP's filed legal name, the assumed name, and its South Carolina registered-office address. The assumed name may not be deceptively similar to the name of a domestic or foreign LP authorized in the state or to a reserved LP name. The statute applies when the LP “conducts or intends to conduct” business under the other name, but it does not add a fixed number of days for filing.

The LP filing has an unusual calendar term

An LP assumed-name certificate expires on December 31 of the fifth full calendar year following the filing year (§ 33-42-45(c)). Thus, the term is not simply five years from the filing date. Renewal is by a new assumed-name certificate filed no earlier than 90 days before expiration, and it adds another five full calendar years. The current Secretary of State form charges $10.

Neither § 33-42-45 nor the official form requires newspaper publication. The statewide publication answer is therefore no, while any separate local-license rule still must be checked with the municipality or county.

LP nonfiling does not invalidate the business

Section 33-42-45(e) expressly protects the LP from the consequences common in other states. Failure to file does not impair a contract or act, does not stop the LP from maintaining or defending a South Carolina court case, and does not turn a limited partner into a general partner merely because the certificate was missed. The section states no separate monetary fine.

What trips people up

• The LP certificate is not a general DBA form. It is available because § 33-42-45 singles out domestic and registered foreign limited partnerships.
• A foreign corporation's “fictitious name” form is also not a general DBA. S.C. Code § 33-15-106 uses it only when the corporation's real name is unavailable and a different name is needed to obtain or maintain authority to transact business in South Carolina.
• The old corporate assumed-name certificates are obsolete. Section 33-4-101 says they could not be renewed and all expired on December 31, 1994.
• Local documentation is not statewide registration. A city or county may put the trade name on a business license or impose another local rule, but the Secretary of State does not receive an ordinary DBA filing.
• Name availability is not ownership. The LP name is screened against specified LP names and reservations, but Secretary of State filing does not by itself supply an exclusive trademark right.

Common questions

I am a sole proprietor using a brand name. Where do I file? Not with the Secretary of State. Start with the city or county where the business operates and ask about its business license and any local DBA documentation.

My LLC wants to use a shorter marketing name. Is the LP form available? No. The § 33-42-45 certificate is limited to limited partnerships. South Carolina does not offer the LLC a general state DBA certificate.

How long does an LP filing made in 2026 last? Through December 31, 2031—the fifth full calendar year after the 2026 filing year. The renewal filing window opens 90 days before that expiration.
