Appointing a South Carolina registered agent, one step at a time
-
Step
1Begin with the legal requirement
Every LLC must name a registered agent with an in-state street address.
Where this comes from: Checked against scstatehouse.gov, October 2026
-
Step
2Find out who can serve
A South Carolina resident, a South Carolina corporation, another LLC, or a corporation or company from another state authorized to do business in South Carolina. You will find this in S.C. Code § 33-44-108.
-
Step
3Use an address that qualifies
The address has to be a street address in South Carolina for the agent, stated in the articles. P.O. boxes are not accepted.
A service gives you a South Carolina street address, which keeps your home address off the filing.
-
Step
4Settle who will be the agent
Our graded agents charge $99 to $149 a year; acting yourself is the other route if you qualify.
-
Step
5Name the agent in the filing
New companies list the agent on the Articles of Organization; changing agents later means filing with the South Carolina Secretary of State again.

The registered agent is all you must maintain, because no yearly report applies.
What you will pay
| Cost item | Goes to | Amount |
|---|---|---|
| Agent service | Your service | $99 to $149 a year |
| Renewing the agent | Your service | $99 to $149 a year |
