South Carolina LLC Tax Guide for Non-Resident Entrepreneurs

Everything you need to know about forming and maintaining an LLC in South Carolina, including state taxes, formation costs, annual requirements, and federal compliance obligations.

Why Choose South Carolina for Your LLC?

No annual report requirement, moderate tax rates, low cost of living, and a growing tech and manufacturing sector, especially in the Charleston and Greenville areas.

South Carolina Tax Overview

Understanding South Carolina's tax structure is essential for non-resident LLC owners. Here's a comprehensive breakdown of all applicable taxes.

Tax TypeRateApplies to LLCs?
Personal Income Tax0% – 6.4%Yes, on SC-sourced income
Corporate/Entity Tax5%C-corps and entities with nexus
Sales Tax6%If selling taxable goods/services
Annual Fee$0 (no annual report required)Yes

Personal Income Tax

South Carolina imposes a personal income tax at rates of 0% – 6.4%. If your LLC is taxed as a disregarded entity or partnership, your share of the LLC's South Carolina-sourced income may be subject to state income tax. Non-residents are generally only taxed on income sourced within South Carolina.

If your LLC has no physical presence, employees, or customers in South Carolina, you likely won't owe state income tax — but you should confirm this with a tax professional familiar with South Carolina nexus rules.

Corporate / Entity Tax

South Carolina imposes a corporate tax rate of 5%. This applies to LLCs that have elected to be taxed as C-corporations. Single-member LLCs treated as disregarded entities for federal tax purposes are generally not subject to the state corporate income tax.

Sales Tax

South Carolina has a state sales tax rate of 6%. Local jurisdictions may impose additional sales taxes. If your LLC sells taxable goods or services in South Carolina, you'll need to collect and remit sales tax. Remote sellers may be required to collect South Carolina sales tax if they exceed the state's economic nexus thresholds (typically $100,000 in sales or 200 transactions).

LLC Formation Requirements

Forming an LLC in South Carolina involves the following steps and costs:

  • Formation fee: $110
  • File with: South Carolina Secretary of State
  • Registered agent: Required (must have a physical address in South Carolina)
  • Operating agreement: Recommended but not always required to be filed with the state
  • EIN application: Required for tax filing (Form SS-4)

Formation Tip for Non-Residents

As a non-resident entrepreneur, you'll need a registered agent service in South Carolina to receive legal and tax documents on your behalf. Registered agent services typically cost $50–$300 per year. You don't need to live in or visit South Carolina to form or maintain an LLC there.

Annual Requirements & Fees

After forming your South Carolina LLC, you'll need to maintain compliance with these ongoing requirements:

Annual Fee$0 (no annual report required)

State Tax FilingMay be required if SC-sourced income

Important Note

South Carolina does not require LLCs to file annual reports, reducing ongoing compliance costs. The state has been attracting major manufacturing operations (BMW, Boeing, Volvo) and a growing tech sector in Charleston. South Carolina also has no state-level franchise tax on LLCs.

Federal Tax Obligations

Regardless of which state your LLC is formed in, non-resident LLC owners must comply with these federal requirements:

  • Form 5472: Required for all foreign-owned single-member LLCs to report transactions between the LLC and its foreign owner. Penalty for non-filing: $25,000.
  • Pro Forma Form 1120: Filed together with Form 5472 as an information return for disregarded entities.
  • ITIN (Form W-7): Non-residents need an Individual Taxpayer Identification Number to file US tax returns.
  • EIN (Form SS-4): Required for all LLCs to open bank accounts and file taxes.
  • FBAR (FinCEN 114): Required if your US financial accounts exceed $10,000 at any point during the year.

Key Federal Deadlines

Form 5472 + 1120: Due April 15 (6-month extension available to October 15)

FBAR: Due April 15 (automatic extension to October 15)
