Charleston County Business License: Unincorporated Areas and the Shared Revenue Portal

If your business operates in the unincorporated parts of Charleston County, you need a Charleston County business license. South Carolina has no general statewide business license. Instead, local business license taxes are levied by most cities and by nine counties, and Charleston County is one of them. The county license covers unincorporated parts of James Island, Johns Island, Wadmalaw and West Ashley. Roughly 13.7% of county residents live in unincorporated areas, so most county businesses sit inside a city and license with that city instead. This guide covers who needs the license, what it costs for the 2026-27 license year, how renewal works, and what changes if you rent property short term or sell taxable goods.

Who Needs the Charleston County License

Start with location, not where you live or where your customers are. The county issues its license for businesses in the unincorporated areas. If your business sits inside a city, that city levies its own license tax, and you apply through the city. Confirm the city's requirements directly with the city before assuming the county license covers you.

Two details trip people up. First, Charleston County Revenue Collections, located at 4045 Bridge View Dr, North Charleston, also processes North Charleston renewals and hospitality filings. A North Charleston business should confirm with Revenue Collections where and how to renew. Second, the license amount is doubled for businesses located outside the county. A company headquartered elsewhere that serves Charleston County customers should confirm its location classification before it pays.

2026-27 License Rates and Classes

Each business falls into a class, and the class sets the amount. The 2026-27 schedule runs from Class 1 to Class 7:

Class	2026-27 amount
Class 1	$35 on the first $2,000, plus $1.25 per $1,000
Class 7	$65 plus $2.75

Classes between these two endpoints follow the same schedule. The per-$1,000 increment declines for amounts above $1 million, so a larger operation does not pay the same rate per thousand as a small one. The table above shows the endpoints only. Confirm your exact class, the increment basis and the bracket that applies to your business with Revenue Collections before you pay, because the class determines the amount you owe. These are 2026-27 figures, and later license years may differ.

Deadlines, Renewal and Late Penalties

The license year runs May 1 to April 30, and renewals are due April 30. Renew online at localblrenewal.com. The SC Revenue and Fiscal Affairs Office directs businesses in participating jurisdictions to this shared renewal site. Before you start, confirm that Charleston County and your city are both listed, because a renewal filed in the wrong place does not satisfy the other jurisdiction's requirement.

A late renewal carries a penalty of 5% per month beginning May 1 (2026). Penalties accrue monthly, so the cost of waiting grows the longer the renewal sits unpaid. Put the April 30 deadline on your calendar in March, and treat the renewal as a fixed annual cost in your budget.

How the Shared Revenue Portal Fits In

The portal handles renewals. For a first-time license, a change in your business classification, or a question about which office handles your filing, contact Revenue Collections directly instead of assuming the online renewal site covers that step. Keep a copy of every receipt, because your renewal record is the proof you will need if a lender, landlord or city office asks for evidence that your license is current.

Charleston County Sales Tax and the Retail License

If you sell tangible goods, you need a retail license from the South Carolina Department of Revenue (SCDOR). The retail license carries a one time, nonrefundable $50 fee per location, and you apply through the Business Tax Application on MyDORWAY at the SCDOR retail license page. The state sales tax rate is 6%. The combined sales tax rate in Charleston County is 9%. After you apply, confirm your filing frequency and remittance schedule with SCDOR, because those details are set on your account and are not part of the license fee.

Charleston County Short-Term Rentals: Zoning Permit Plus Business License

Operating a short-term rental in unincorporated Charleston County takes two approvals. You need a county zoning permit for the property, and you need the business license. The zoning permit is renewed yearly. Most residential zoning districts limit rentals to 72 rental days a year, so check the parcel's zoning district before you list the property on any platform. A business license does not authorize a rental in a district that restricts it, and a zoning permit does not replace the license.

Lodging taxes add another layer. Charleston County charges a 2% accommodations fee on stays under 30 nights. The county does not currently impose a county hospitality tax, but confirm the current rates with Revenue Collections, because local tax rates change and a single outdated rate can leave you underpaying.

Charleston County Zoning Is a Separate Question

Zoning and licensing are different systems. Zoning controls what can be built on a parcel and what activities a property can host, while the business license is a tax and registration requirement. Holding a license does not establish that your use is allowed on the site. Check zoning before you sign a lease, buy property or begin a home-based operation, and contact the county zoning office with questions about your specific parcel. If a zoning question is contested, an attorney who handles land use should review it before you spend money on the space.

Other South Carolina Filings That Affect Your Setup

• No state general business license. Registration with the Secretary of State is not a business license. Your county or city license is the local requirement.
• LLCs. The Articles of Organization carry a $110 filing fee, filed online through Business Entities Online at businessfilings.sc.gov. An LLC that is not taxed as a corporation files no annual report.
• DBAs. The Secretary of State does not register DBA or trade names. Record the DBA with the county or city, typically on your local business license, and list the trade name on your IRS EIN application and your SCDOR Business Tax Application.
• Retail food. Food permits come from the South Carolina Department of Agriculture, not DHEC, which was split in 2024. Apply to the Department of Agriculture for any food operation.
• Contractors. Commercial contractor licensing applies to work above $10,000, and residential specialty contractor registration applies above $500.

Step-by-Step Checklist

1. Confirm whether your business is in the unincorporated county or inside a city, and whether it sits inside Charleston County.
2. Confirm your class and the applicable amount with Revenue Collections before you pay.
3. Check the zoning district for any short-term rental or home-based use, and apply for the county zoning permit if the property is a short-term rental.
4. If you sell tangible goods, apply for the $50 SCDOR retail license for each location.
5. Calendar the April 30 deadline and renew at localblrenewal.com before it passes.
6. Save every receipt and permit so you can prove your license and zoning status on request.

When to Get Professional Help

A zoning dispute, a short-term rental on a contested parcel, or a multi-location business with sales in several jurisdictions is complex enough to warrant an attorney's review. Questions about sales tax filing, the accommodations fee or entity tax treatment belong with a certified public accountant. The South Carolina Small Business Development Centers at scsbdc.com can help you work through formation and licensing questions before you commit to a structure or a location.

This guide is informational content, not legal or tax advice. Rates, deadlines and local rules change, and the figures above are for the 2026-27 license year. Confirm every amount and requirement with Charleston County Revenue Collections, the South Carolina Department of Revenue or the relevant city before you file or pay, and consult a qualified attorney or CPA for your specific situation.
