Step-by-step LLC filing in South Carolina, written by a bookkeeper who’s done it

You want the legal shield without a pile of red tape. In South Carolina the process is straightforward, and the dollars involved are clear if you know where to look: the Articles of Organization cost $110, a state Retail License is a one-time $50 per location if you’ll collect sales tax, and a city business license often kicks in once you start operating. Here’s how I file an LLC for clients in South Carolina, what I actually pay, and where the state will ask you for a check.

Name it right and line up a registered agent

Start with the state’s free name search in Business Entities Online. If you’re not ready to file today but don’t want to lose the name, you can reserve it for 120 days by filing the Application to Reserve a Limited Liability Company Name. The reservation fee is $25 and it’s optional. If you’re ready to organize now, skip the reservation and go straight to filing to avoid paying twice.

Every South Carolina LLC must maintain a registered agent with a South Carolina street address who is available during normal business hours to receive legal papers. A P.O. Box will not satisfy this. Many owners serve as their own agent at the company’s place of business; others hire a commercial provider. If you appoint yourself, be sure you are reliably available at that address 9–5 on weekdays, because missed service of process can snowball into default judgments you never saw coming.

One practical note from the trenches: if you expect to move soon or you work irregular hours, a commercial agent is often simpler than re-filing address changes or risking a missed delivery. If you change your agent or your agent’s street address later, the state’s change form is quick to file, and small administrative filings like this typically carry a single-digit or low two-digit fee by statute.

File the Articles of Organization and get your proof

You create the LLC by filing Articles of Organization with the South Carolina Secretary of State. You can file online through Business Entities Online or send a paper form to the Secretary of State’s office at 1205 Pendleton Street, Suite 525, Columbia, SC 29201. The formation fee is $110 either way.

Online filing is the norm now because you get immediate submission confirmation and the state issues your stamped proof as soon as the filing is accepted into the system. Mailed filings add postage time and manual handling in Columbia. If you plan to open a business bank account right away, consider also ordering a Certificate of Existence from the Secretary of State. It costs $10 and many banks will accept it as same-day proof your LLC exists and is in good standing.

Foreign company coming into the state? An out-of-state LLC registers by applying for a Certificate of Authority with the Secretary of State and paying $110. South Carolina requires a certificate of existence from your home state that is not more than 30 days old when you file the application.

Do you need a lawyer to sign? No. The organizer is the person who signs the Articles. You’ll list your registered agent’s name and South Carolina street address, the LLC’s name with “LLC,” “L.L.C.,” “LC,” or similar designator, and whether the company is member- or manager-managed. Owners’ names are not required in the public filing, which is why I always prepare a private Operating Agreement for clients next, even though it is not filed with the state.

Handle tax registrations in the right order

First, get the EIN from the IRS

Apply for the federal EIN online with the IRS. The cost is $0. The confirmation letter is what your bank and the South Carolina tax portal will expect to see.

Then register with the South Carolina Department of Revenue (SCDOR)

If you will sell taxable goods or certain services, you must obtain a South Carolina Retail License before your first taxable sale. The license costs $50 one time per location. You register through SCDOR’s online portal and can add other accounts like Withholding if you will have employees. South Carolina’s statewide Sales and Use Tax rate is 6%, with local add-ons in many jurisdictions. The Retail License does not renew annually if you keep operating at the same location; it stays valid unless revoked or you move.

If you don’t sell at retail but you do have employees, register only for Withholding so you can remit state income tax withheld from wages. The SC W‑4 form and withholding tables get updated annually; as of 2026, SCDOR offers a free two-hour Employer Withholding Tax workshop that covers how to deposit and file. Budget your time and cash flow accordingly, because missing early payroll deposits often hurts more than any other first‑year mistake.

Local business licenses and a bank account that won’t fight you

Most South Carolina cities require an annual business license to operate within city limits. For a clear example, the City of Charleston’s business license fee uses a base charge of $64 plus $3.90 per additional $1,000 of expected gross income for many common NAICS classes. New Charleston businesses can apply in person at the Permit Center, 2 George Street, Suite 3700, Charleston, SC 29401, open Monday–Friday, 8:30 a.m.–5:00 p.m.. If you’re operating in another municipality, check that city’s schedule, because South Carolina uses a standardized classification system but the base and per‑$1,000 rates vary by city and by NAICS class.

Your bank will ask for your EIN letter, stamped Articles of Organization, and often a Certificate of Existence from the Secretary of State. Plan ahead for the $10 certificate fee and bring your Operating Agreement if there is more than one member, because many banks want to see who is authorized to sign. If you’re opening the account the same week you file, choose online formation and order the certificate as soon as your entity appears as “In Good Standing” in the state’s system.

Employees, unemployment insurance, and payroll basics

Hiring employees triggers unemployment insurance and withholding obligations. Register for unemployment insurance through South Carolina’s online SUITS system, administered by the Department of Employment and Workforce (SCDEW). For 2026, the unemployment insurance wage base is $14,000 per employee. New employers start at the new‑employer rate set by law, which is the tax rate for Class 12 or 1.0%, whichever is higher for that year. Experienced employer rates range by class. These percentages apply only to wages up to the wage base, so your maximum unemployment insurance cost per employee is capped within the table SCDEW publishes each year.

On the withholding side, once you have an SCDOR withholding account you’ll use the state’s forms or approved payroll software to calculate and remit South Carolina income tax withheld from wages. Keep the SC W‑4 on file for each employee. If you keep payroll in‑house, calendar both the deposit due dates and the periodic return due dates. The most common early‑stage cash crunch I see is payroll taxes that weren’t set aside weekly. Treat withholdings as trust funds, not working capital.

Which tax path fits your LLC: stay default or elect S corporation?

Forming an LLC sets up the legal shell; taxes are a separate choice. By default, a single‑member LLC is disregarded for income tax and a multimember LLC is a partnership. You can elect corporate taxation, most often S corporation status, after formation. In South Carolina, that choice changes some real costs and filings. Here is the side‑by‑side I walk clients through.

Two concrete timing items if you choose S corporation status. First, calendar the CL‑1 filing within 60 days of commencing business or using capital in South Carolina so you do not trigger penalties. Second, budget the annual corporate license fee minimum of $25, even in a low‑revenue year. An LLC that does not elect corporate taxation has neither of those two line items.

Your filing checklist, in real‑world order

1) Confirm the name and, if needed, reserve it

Search the Secretary of State’s database to confirm the name is available. If you want to hold the name before you file, submit the reservation for $25 to lock it for 120 days.

2) Line up a South Carolina registered agent

Decide whether you or a commercial agent will serve. The agent must have a South Carolina street address and be available during normal business hours.

3) File Articles of Organization and pay $110

File online via Business Entities Online or mail the paper form to 1205 Pendleton Street, Suite 525, Columbia, SC 29201. Keep the stamped Articles once accepted. If you’ll need to prove status to a bank or a licensing office, order the $10 Certificate of Existence as well.

4) Draft and sign your Operating Agreement

This stays internal to the company but avoids disputes. Spell out who can sign at the bank, how profits are split, and who replaces the manager if someone steps back. Banks often want to see this when more than one person is on the account.

5) Get the EIN ($0)

Apply online with the IRS and download the EIN letter immediately. Save the PDF to the same folder as your stamped Articles and Operating Agreement; you’ll upload all three a lot in year one.

6) Register with SCDOR

If you will sell taxable items or services, apply for the South Carolina Retail License and pay $50 per location. Add Withholding if you will run payroll. The statewide sales tax rate is 6% before local add‑ons.

7) Secure your local business license

Check the city where you will operate. For example, the City of Charleston collects a base $64 plus $3.90 per additional $1,000 of expected gross income for many common NAICS classes and accepts walk‑ins at 2 George Street, Suite 3700 from 8:30 a.m. to 5:00 p.m., Monday–Friday. Your city will have its own schedule tied to your NAICS code.

8) Open the business bank account

Bring the EIN letter, stamped Articles, Operating Agreement, and consider a $10 Certificate of Existence if asked. Ask the banker what their monthly fee waiver requires so you can set up the right number of transactions and minimum balance from day one.

9) If you will have employees, register with SCDEW

Use SCDEW’s online SUITS system to get an unemployment insurance account number. For 2026, the UI wage base is $14,000 per employee and the new‑employer rate is the Class 12 rate or 1.0%, whichever is higher for the year. Set calendar reminders for both wage reporting and payments.

10) Keep the state‑level nuance straight

South Carolina LLCs that do not elect corporate taxation have no Secretary of State annual report and no corporate license fee. If you elect corporate taxation, you must file the CL‑1 and pay the $25 license fee within 60 days of starting business, and then pay the annual license fee minimum of $25 with your corporate return. If you will sell at retail, the Retail License is $50 once per location. Keep these on a one‑page calendar with their amounts so nothing gets missed.

Reader Q&A

Do South Carolina LLCs file an annual report with the Secretary of State?

No, a standard South Carolina LLC has no Secretary of State annual report or annual LLC fee. That changes only if you elect to be taxed as a corporation, in which case you file a CL‑1 initial report and pay at least a $25 corporate license fee annually with your corporate return.

How much cash should I set aside for state registrations in month one?

Plan on $110 for the Articles of Organization, $10 if you order a Certificate of Existence for banking, and $50 for a Retail License if you will sell taxable items. If you operate in a city, add the first‑year business license charge, which in Charleston starts with a $64 base plus $3.90 per additional $1,000 of projected income.

Can I walk in somewhere to get help in person?

Yes. You can file by mail or online with the Secretary of State, and Charleston accepts business license walk‑ins at 2 George Street, Suite 3700, open Monday–Friday, 8:30 a.m.–5:00 p.m.. For formation help by phone, the Secretary of State’s Business Filings number in Columbia is widely published and staffed on weekdays.

What order should I follow so the bank doesn’t send me away?

File the Articles and wait for acceptance, get the EIN ($0), order a $10 Certificate of Existence if the bank asks for it, then bring those plus your Operating Agreement to open the account. If you’ll collect sales tax, complete the $50 Retail License application as you set up your point of sale so it’s in place before your first sale.

When you’re choosing between staying the default tax classification and electing S corporation status, write out the added filings and the license fee minimums next to your projected payroll and profit. Pick the path where the math on your actual numbers works, not the one that sounds better in theory.
