Best South Carolina LLC Formation Service in 2026

South Carolina is one of the friendliest US states for a small LLC's ongoing cost: most LLCs don't have to file an annual report or pay an annual fee. Filing fee is $125 once, and unless you elect corporate tax treatment, that's basically it from the state's side. Online approval typically lands within 1–2 business days, among the faster portals.

So the meaningful choice isn't really "Should I form in SC?" — it's "Which formation service gets me to a Mercury account quickest without overcharging on year-2 registered agent renewal?"

South Carolina LLC basics

Filing fee: $125 for Articles of Organization (online)
Annual report: None for standard LLCs. Only LLCs that elect to be taxed as C-corporations (rare for one-person companies) file an annual report with the SC Department of Revenue.
State income tax: SC honors federal pass-through treatment; members report their share on personal returns. SC has a graduated personal income tax up to ~6.2%.
Privacy: Articles of Organization are public, including registered agent name and address. Member names are not required on the Articles. Using a registered agent service keeps your personal address off filings.
Naming: must include "LLC", "L.L.C.", or "Limited Liability Company"
Registered agent: must have a physical SC street address (no PO boxes)
Processing time: 1–2 business days for online filings — among the faster state portals
No statewide general business license, but local licenses may apply (Charleston, Greenville, etc.)

The zero-annual-report rule alone makes SC a strong pick for founders who want minimal yearly maintenance. Over 5 years you'll save $1,000+ compared to a state like North Carolina ($200/yr).

Service-by-service breakdown

1. Doola — best for non-US founders forming a South Carolina LLC

Pricing: Starter $297/yr, Total Compliance $799/yr
What's included: LLC filing + EIN (handles SS-4 paper filing for non-SSN founders) + Registered Agent (1 yr) + US business address + Mercury Bank introduction
Turnaround: 2–4 weeks for non-US founders (EIN paper filing bottleneck), 3–7 days for US founders
Why we use it: Non-US founders consolidate four vendors into one. SS-4 paper EIN is the kill-switch step — without it, you wait 6–12 weeks on IRS mail.
Caveat: Starter is more expensive than Northwest at renewal. SSN holders optimizing for raw cost should use Northwest + DIY EIN.

2. Northwest Registered Agent — best for US residents who want privacy

Pricing: $39 service fee + $125 state filing + $125/yr registered agent after year 1
Includes: LLC filing + 1 yr registered agent + privacy (their name on public records)
EIN: +$50, US-only
Pick if: US resident, SSN, value low-noise support

3. ZenBusiness — US founders on a budget

Pricing: Starter $0 + state, Pro $199/yr, Premium $349/yr
Caveat: Renewal upsells; registered agent jumps to $199/yr in year 2

4. LegalZoom — brand recognition, expensive

Pricing: Basic $0 + state, Pro $249, Premium $349
Caveat: Registered agent +$249/yr is the priciest; cancellation friction

5. Bizee (formerly IncFile) — free starter

Pricing: Free + state, Gold $199, Platinum $299
EIN: +$70
Caveat: With no SC annual report to miss, Bizee's weak compliance tracking is less risky here than in PA or NC — but their support is still spotty

6. DIY — for US founders with SSN, address, and patience

Cost: $125 state filing + ~$125/yr registered agent + free EIN online (SSN required)
Pick if: You want minimum total cost; SC's no-annual-report rule makes DIY especially low-maintenance
Skip if: Non-US — SS-4 paper EIN filing from outside the US is the bottleneck

Step-by-step South Carolina LLC formation

Choose a name — must include "LLC", "L.L.C.", or "Limited Liability Company". Check availability at the SC SOS business search.
Designate a registered agent — must have a physical SC street address (no PO boxes).
File Articles of Organization — $125 to the SC Secretary of State. Online approval typically 1–2 business days.
Draft an Operating Agreement — not required by SC, but every bank will ask.
Get EIN from IRS — free online with SSN; SS-4 paper filing 4–8 weeks for non-US founders (Doola handles this).
Open a US business bank account — Mercury Bank, 3-hour approval if LLC + EIN are clean.
Local business license (if applicable) — Charleston, Columbia, Greenville and other cities require their own local business licenses. Check the city if you'll have a real local presence.
Ongoing compliance — for standard pass-through LLCs, nothing at the state level. Just keep your registered agent active.

FAQ

Does South Carolina really not require an annual report?
For standard pass-through LLCs, correct — no annual report and no annual fee. The only LLCs that file an annual report are those that elected to be taxed as C-corporations, which is rare for one-person companies. Confirm your tax election with a CPA if you're unsure.

Can a non-US resident form a South Carolina LLC?
Yes. No citizenship or residency requirement. You need an SC-based registered agent (any service above provides this) and the SS-4 paper EIN path (Doola handles it).

Is South Carolina better than North Carolina for non-US founders?
On ongoing cost, yes — SC has no annual report while NC charges $200/yr. The filing fee is the same ($125). Unless you have specific NC business activity, SC is the cheaper Carolina to form in.

Is South Carolina competitive with Wyoming for privacy?
Not quite. SC's Articles of Organization include the registered agent's name and address as public information, but using a registered agent service masks the founder's personal address. Wyoming and New Mexico are stronger on outright owner anonymity. SC's strength is low ongoing cost, not maximal privacy.
