Why consult with a South Carolina business startup lawyer?

Starting a business involves navigating a complex array of legal and tax requirements at both the state and federal levels. Business owners must understand the available entity types, the legal structures, and their respective tax implications before making a decision. In my 25 years as a business lawyer, I have advised hundreds of startup businesses on the legal and tax considerations involved in choosing a business entity, the steps to form a business in South Carolina, and the filings required to be compliant with South Carolina and federal laws. I have assisted in the formation of hundreds of businesses.

1. Choosing the Right Business Entity

Choosing the right business entity is the first major decision when forming a business, perhaps second only to choosing the name. Choosing one business entity (whether an LLC, corporation, partnership, or sole proprietorship) over another requires consideration of personal and business asset protection issues, management flexibility and control matters, taxation, ease of maintenance issues, capitalization and securities issues, and transferability of ownership rights, to name just a few. In South Carolina, businesses can be formed as sole proprietorships, partnerships, limited liability companies (LLCs), or corporations (C-Corporations or S-Corporations), Public Benefit Corporations, and non-profit organizations.

Key Types of Business Entities in South Carolina

a.  Sole Proprietorship

A sole proprietorship is the simplest business form, owned and operated by a single individual. It does not require any formal registration with the state, but it is important to obtain local licenses and permits.

Liability: The owner has unlimited personal liability for business debts.</p></p>

Taxation: The business’s income is reported on the owner’s personal tax return (Form 1040, Schedule C).

Filings: Sole proprietors may need to register for an EIN (Employer Identification Number) with the IRS if they have employees or if they operate under a name other than their own.

b.  General Partnership

A general partnership is formed when two or more individuals share ownership and management responsibilities. Like sole proprietorships, no formal state registration is required, but partnership agreements are recommended.

Liability: Partners share unlimited personal liability for the partnership’s debts and obligations.

Taxation: Partnerships are pass-through entities, meaning they do not pay income taxes. Instead, income and losses are passed through to the individual partners, who report them on their personal tax returns.

Filings: Partnerships may need to obtain an EIN and file Form 1065 (Partnership Return of Income) with the IRS. Partners report their share of income on Schedule K-1.

c.   Limited Liability Company (LLC)

An LLC combines the limited liability protection of a corporation with the tax flexibility of a partnership. It is one of the most popular business structures due to its flexibility.

Liability: LLC members have limited liability for the company’s debts and obligations.

Taxation: By default, LLCs are pass-through entities for federal tax purposes. Single-member LLCs are taxed as sole proprietorships, and multi-member LLCs are taxed as partnerships. However, LLCs can also elect to be taxed as a corporation (S-Corp or C-Corp) by filing with the IRS.

Filings: LLCs must file Articles of Organization with the South Carolina Secretary of State and obtain an EIN from the IRS. LLCs taxed as S-Corporations must file Form 2553 with the IRS.

d.  Corporation (C-Corp)

A C-Corporation is a separate legal entity that provides limited liability protection to its shareholders. Corporations are subject to corporate income tax and other formalities.

Liability: Shareholders have limited liability for corporate debts and obligations.

Taxation: C-Corporations are subject to double taxation—first at the corporate level (with the federal corporate tax rate of 21%) and again at the shareholder level on dividends.

Filings: To form a C-Corp, you must file Articles of Incorporation with the South Carolina Secretary of State. You will also need to obtain an EIN from the IRS and file Form 1120 for corporate tax returns.

e.  S-Corporation (S-Corp)

An S-Corporation is a tax designation available to small corporations that elect to pass corporate income, losses, deductions, and credits through to their shareholders for federal tax purposes. S-Corps are subject to fewer taxes than C-Corps.

Liability: Shareholders enjoy limited liability.

Taxation: S-Corps are pass-through entities, so the business itself does not pay federal income taxes. Instead, income is reported on the shareholders’ individual tax returns (Form 1120S).

Filings: To form an S-Corp, you must file Articles of Incorporation with the Secretary of State, obtain an EIN, and file Form 2553 with the IRS to elect S-Corp status.

f.  Non-Profit Corporation

Non-profit corporations are organized for charitable, educational, religious, or other tax-exempt purposes.

Liability: Directors and officers typically have limited liability for the corporation’s debts.

Taxation: Non-profits can apply for tax-exempt status under Section 501(c)(3) of the Internal Revenue Code, which exempts them from federal income tax.

Filings: Non-profits must file Articles of Incorporation with the South Carolina Secretary of State and apply for 501(c)(3) status with the IRS using Form 1023 or Form 1023-EZ for smaller organizations.

2.  Legal Requirements and Filings for Forming a Business in South Carolina

Step 1: Choose Your Business Name

The business name must be unique and distinguishable from other registered entities in South Carolina.

For corporations and LLCs, the name must include specific terms (e.g., “Inc.”, “Corp.”, “LLC”). You can check name availability through the South Carolina Secretary of State’s online database.

Business often use their business name, called a “trade name,” as a trademark or service mark. Trademark or service mark registration is highly recommended but even if a business elects not to register a mark proper due diligence must be performed to ensure that your use of that trade name and/or trade mark or service mark does not infringe on the rights of others. A name availability check with the South Carolina Secretary of State’s online database is insufficient for this purpose.

Once a name is chosen for the business, one or more domain names are usually checked for availability and purchased. Since many or most domain registrars sell lists of domain searches to unscrupulous domain squatters and others, care must be exercised against performing domain searches that are not immediately or promptly acted on.

Step 2: Appointing a Registered Agent

All business entities, including corporations and LLCs, must appoint a registered agent with a physical address in South Carolina to receive legal documents (such as lawsuits and official correspondence).

Step 3: Filing Articles of Incorporation (Corporations) or Articles of Organization (LLCs)

For corporations, file Articles of Incorporation with the South Carolina Secretary of State. These documents typically include the corporation’s name, registered agent, number of shares (for corporations), and other important details.

For LLCs, file Articles of Organization with the Secretary of State. These documents typically include the LLC’s name, registered agent, and type of management (member-managed or manager-managed).

Step 4: Obtain an Employer Identification Number (EIN)

Most businesses must obtain an EIN from the IRS, which is used for tax purposes, hiring employees, and opening a business bank account.

Form SS-4 is used to apply for an EIN.

Step 5: Draft an Operating Agreement (for LLCs) or Bylaws (for Corporations)

An Operating Agreement is not mandatory in South Carolina for LLCs, but it is highly recommended as it defines the management and financial structure of the business.

Corporations must have bylaws that govern internal operations, including the roles of directors and shareholders.

Step 6: File CL-1 Initial Annual Report

Entities, whether corporations or LLCs, that are taxed as corporations file the Initial Annual Report (Form CL-1) through the Secretary of State, which forwards it on to the South Carolina Department of Revenue. The filing fee is generally $25 for LLCs and $25 for corporations.
