Few states make owning an LLC as low-maintenance as South Carolina does. The filing fee is reasonable, there's no franchise tax lurking anywhere, and most LLCs never have to file anything at all with the state once they're formed. Here's the practical rundown on getting a business started in South Carolina in 2026.
1. Which business structure fits you?
The decision usually comes down to liability exposure versus how much administrative overhead you want to take on.
- Sole proprietorship. Nothing to file to get started, but you and the business are one legal entity, meaning its debts are yours to cover.
- Partnership. Two or more owners sharing the same personal liability a sole proprietor carries, just divided among partners.
- LLC. What most small South Carolina businesses choose, since it puts a legal barrier between your personal assets and the business's debts or lawsuits.
- Corporation, S-corp or C-corp. More formal and paperwork-heavy, generally worth it once you're bringing in investors or multiple shareholders. Worth flagging now: LLCs taxed as S-corps are the one carve-out to South Carolina's no-annual-report policy described below.

LLCs and corporations file with the South Carolina Secretary of State, the office that handles business registration for the whole state. Sole proprietorships and general partnerships don't need to file there.
2. Register your business
Forming an LLC
An LLC comes into existence in South Carolina by filing Articles of Organization with the Secretary of State. It costs $110 by mail or $125 online, the $15 difference covering electronic records access, and online filings generally clear in about 24 hours.
Every LLC needs a registered agent at a physical South Carolina address, staffed during business hours. Fill that role yourself, or hand it off to a commercial service.
There's no legal obligation in South Carolina to draft an operating agreement. Multi-member LLCs should have one anyway, since it's what settles how decisions get made and profits get split before anyone disagrees about it.
Sole proprietorships and DBAs
Sole proprietors have no reason to file with the Secretary of State. Operating under a trade name is handled differently depending on your county, so check with local government there before assuming a single statewide process applies.
3. Get an EIN
An Employer Identification Number costs nothing through the IRS, and the online application generally wraps up in about 15 minutes. You'll be asked for one to open a business bank account, to hire anyone, and for most business tax filings, single-member LLC with no employees included.
4. Check licenses and permits
There's no single statewide business license that covers everyone in South Carolina. What you need instead depends on industry and city: regulated professions need their own licensing, cities like Charleston and Columbia require a local business license, and selling taxable goods calls for a Retail License from the Department of Revenue. Our guides to industry-specific licensing and home-business zoning rules cover more ground.
5. Understand South Carolina taxes
South Carolina reworked its income tax starting in 2026, moving to a two-bracket system: 1.99% on taxable income up to $30,000, and 5.21% on anything above that (with a small fixed adjustment), replacing a graduated structure that had topped out around 6% to 6.5%. Pass-through LLCs owe nothing under a separate franchise tax here.
Sales tax opens at a 6% state base rate, and counties can layer on local option taxes of up to 3% more, which pushes combined rates as high as roughly 9% in places like Charleston and Myrtle Beach.
6. Stay compliant
There isn't much to track here, since South Carolina doesn't require most LLCs to file an annual report with the Secretary of State at all. The one exception is an LLC that elects S-corporation tax treatment, which does have an annual filing obligation. Everyone else's ongoing state responsibility really comes down to keeping a registered agent on file and staying current on whatever taxes actually apply.
