What owners want to know

Does the law insist on a registered agent?

Every LLC must name a registered agent with an in-state street address.

Read the law: S.C. Code § 33-44-108. see scstatehouse.gov, October 2026

Who qualifies as an agent?

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.

If you meet the rule, you may name yourself and avoid paying an agent.

How much does an agent charge?

Budget $99 to $149 each year, $297 to $447 for three years.

Whichever agent you choose, the state charges the same.

What does an agent do for the LLC?

It serves as the LLC's address in South Carolina for court papers and state letters.

If papers arrive and nobody takes them, a case could proceed without you. What does service of process mean?

What does the LLC owe the state every year?

There is no report to file and no report fee.

How did you order the services?

The deciding factor is how much work the price handles (28% of the weight), where Mainstay Filing is strongest.

Our weighting leans on what three years cost first and how much work the price handles second, then three smaller factors.

Coverage settled it: all fifty states against one.

Further questions

Can I serve as the agent myself?

What is the three-year price of each?

Mainstay Filing: $447 | SC Registered Agent.org: $297 | South Carolina Registered Agent.co: $297

How do you know these fees?

Each state fee links to its official source, and each service price comes from the company's website.

Is a service required?

Not required. Services charge to do the paperwork for you.

Which registered agent do you recommend in South Carolina?

Mainstay Filing is on top because the $149 yearly price is identical across states; SC Registered Agent.org and South Carolina Registered Agent.co follow.
