Dorchester County Business License: What You Need to Know

If you plan to open or run a business in Dorchester County, South Carolina, you will face a question the state does not answer for you. South Carolina has no statewide general business license. Cities, towns, and a small group of counties levy their own business license taxes instead, and Dorchester County is one of them. Your Secretary of State filing does not replace that local license, and which license you need depends on where your business is physically located.

This guide covers the dorchester county sc business license, how the county rate classes work, where county licensing stops and town licensing starts, and the sales tax and dorchester county zoning steps that owners often miss. It is informational content, not legal or tax advice. Confirm current rates and deadlines with the agency named in each section before you pay.

Does Dorchester County Require a Business License?

Yes, if your business operates in the county's licensing area. Dorchester County levies a local business license tax, and it is one of only nine South Carolina counties that do so. The other eight are Beaufort, Charleston, Horry, Jasper, Marion, Orangeburg, Richland, and Sumter. Most South Carolina cities levy their own business license tax as well.

The county license is a local registration with its own rate schedule, and it is separate from everything you file with the state. SC Business One Stop is explicit that registering with the Secretary of State is not a business license. Your business still needs the local license for its location, even after your LLC or corporation is formed.

Where the County License Applies

The county licenses businesses in its unincorporated areas. That includes Ladson and the unincorporated land around Ridgeville and Summerville. About 54.6% of the county is unincorporated, so a large share of the county's business base falls under county licensing rather than a town or city.

The Town of Ridgeville and the Town of Summerville each license separately. If your address is inside either town limits, the town is the licensing authority, not the county. Ask before you apply, because paying the wrong jurisdiction does not satisfy the other one.

Summerville and North Charleston straddle the county line, so two businesses on the same road can fall under different licensing authorities. Check the physical address of the business, not the mailing address or the city name in the postal address. Confirm the jurisdiction with the county office before you sign a lease.

One common point of confusion: Volvo Cars Ridgeville is in Berkeley County, not Dorchester County. If a job posting, supplier record, or delivery address suggests a Dorchester location because of the Ridgeville name, check the county on the address before you apply anywhere.

2026-27 Rates, Due Date, and Penalties

The license year runs May 1 to April 30, and the license is due April 30. The county's rate schedule is based on classes, and the 2026-27 license year runs from Class 1 to Class 7.

Item	2026-27 county rule
License year	May 1 to April 30
Due date	April 30
Class 1	$30 on the first $2,000, plus $0.75 per $1,000
Class 7	$60 plus $1.53
Late penalty	5% per month, starting May 1

The per-thousand rate steps down on amounts above $1 million, so a larger business does not pay the full rate on every dollar. The classes between Class 1 and Class 7 follow the county's full schedule, which you should request from the county before you estimate your cost.

Businesses located outside the county pay double the amount. If you are relocating or opening a second location, confirm which side of the line each site falls on, since the difference can be significant.

Renewals are handled through localblrenewal.com at https://localblrenewal.com, a service of the South Carolina Revenue and Fiscal Affairs Office.

Steps to Get Licensed in Dorchester County

Most owners need to complete these steps in roughly this order. Not every step applies to every business, so use the list as a checklist rather than a rule for your specific situation.

1. Choose your business structure and check the name. An LLC name must include limited liability company, limited company, LLC, L.L.C., LC, or L.C., and the name must be distinguishable from other registered names on Secretary of State records. You can reserve a name for $25 for 120 days, and the reservation cannot be renewed.
2. File formation documents with the Secretary of State. An LLC files Articles of Organization under S.C. Code Section 33-44-203 for a $110 filing fee. A corporation files Articles of Incorporation under S.C. Code Section 33-2-102 for a $110 filing fee, signed by a South Carolina attorney, together with Form CL-1 and its $25 minimum license fee ($135 total). Online filing through Business Entities Online at https://businessfilings.sc.gov/ is returned within 24 to 48 business hours. The Secretary of State does not publish an expedite fee.
3. Name a registered agent. An LLC must maintain a South Carolina office and an agent for service of process. The agent can be a South Carolina resident, a domestic corporation, another LLC, or an authorized foreign entity. The agent's name and address must appear on the formation document.
4. Get your federal EIN and state tax account. Apply for the EIN with the IRS and register through the SC Department of Revenue Business Tax Application. If you operate under a trade name, list it on both applications.
5. Get the SCDOR retail license if you sell tangible goods. The retail license costs a one-time, nonrefundable $50 per location and is applied for through the Business Tax Application on MyDORWAY.
6. Apply for the local license. Use the county or town that covers your address, as described above.
7. Check industry permits. Retail food permits come from the South Carolina Department of Agriculture, not DHEC, which was split in 2024. Commercial contractor licenses apply to work above $10,000, and residential specialty registration applies above $500. Confirm current thresholds with the agency before you bid.

Sole proprietors and general partnerships do not file organizing documents with the Secretary of State at all, but they still need the local license and any tax registrations that apply.

Annual Reports and Ongoing Filings

A standard LLC in South Carolina does not file an annual report with the Secretary of State and pays no annual report fee. A corporation has different obligations. Its Form CL-1 and $25 initial License Fee are due within 60 days of doing business or using capital in South Carolina. Its annual report is filed as Schedule D with the SC1120 or SC1120S, and the recurring License Fee is 0.1% of capital and paid in surplus plus $15, with a $25 minimum. The annual report and fee are due on the 15th day of the fourth month after the business year ends.

An LLC that elects to be taxed as a corporation follows the corporate filing requirements above, so confirm your tax election before you assume you have no annual obligations.

Dorchester County Zoning: A Separate Check

A business license does not confirm that your intended use is allowed at your address. Zoning controls how a parcel can be used, and it can affect whether you can operate from a particular building, what signs you can display, and how parking and access must be arranged. Dorchester County zoning applies in unincorporated areas, while a town applies its own zoning inside its limits.

Before you sign a lease or buy property, ask the county office at 500 N Main St, Summerville, which department handles zoning for the specific parcel. Get the answer in writing if the use is central to your business plan. Zoning questions are separate from the license, so a clean license application does not mean the zoning question is settled.

Dorchester County Sales Tax

The South Carolina state sales tax rate is 6%. If you sell tangible goods, you need the SCDOR retail license described above, which costs $50 per location as a one-time, nonrefundable fee. Apply through the Business Tax Application on MyDORWAY at https://dor.sc.gov/businesses/apply-business-tax-account/licensing-retail-license.

Dorchester County also levies local taxes on hospitality and accommodations. A Revenue and Fiscal Affairs Office report for FY2023-24 lists a 2% hospitality tax and a 2% accommodations tax in the county. Check with the county for the current rates and for exactly which sales each tax covers, because the rates and scope can change. Confirm with SCDOR whether any local add-on applies at your address, so you collect the correct total at the register.

Common Mistakes to Avoid

• Assuming the Secretary of State filing covers your local license. It does not.
• Applying to the wrong jurisdiction near the Summerville and North Charleston county line.
• Missing the April 30 due date. The 5% monthly penalty starts May 1.
• Treating a Ridgeville address as a Dorchester address without checking the county on the parcel.
• Assuming a DBA requires a state filing. There is no state DBA registration. South Carolina Business One Stop directs owners to put a DBA on the local business license and to list it as a trade name on the EIN application and the SCDOR Business Tax Application.
• Assuming an LLC owes an annual report. A standard LLC does not, but a corporation does.
