A limited liability company in general does not have to pay any business taxes. When we talk about the classification of LLC taxes in South Carolina, we know that it is a pass-through taxation structure. Typically, the profit LLC makes passes through the LLC to its members. Based on the profit share, members file their income tax returns. LLCs, unlike other corporations, do not have to pay income taxes based on profit or revenue.

IRS (Internal Revenue Service) allows LLCs to choose their preferable classification of tax at the beginning of the LLC formation. In general, a single-member LLC is taxed as a sole proprietor and a multi-member LLC is taxed as a partnership. As there is no fixed tax structure for LLCs, anyone certainly wants to opt for the most beneficial one. Keep reading till the end to know more about the tax structure of an LLC in South Carolina and related aspects.

Classification of South Carolina LLC Taxes

An LLC is considered a Pass-through Entity because it allows the income to pass through & become self-employment income. The members of the LLC have to pay Self-employment tax or Self-Employment Taxes on any income they earn through the LLC. The LLC has to pay Franchise Tax on its income. In addition to the Self-employment tax, there are some other requirements that an LLC has to consider, such as:

  1. Franchise Tax – Franchise tax applies to or levies upon LLCs, C-corporations, & S-corporations. Sole Proprietorship & Partnerships (directly owned by individuals) are exempted from the Franchise Tax. This tax is to be paid with the office of the Comptroller of Public Accounts.
  2. Federal Tax Identification Number – An LLC with employees must obtain a Federal Tax Identification Number. South Carolina does not have a separate State Tax Identification number.
  3. State Employer Taxes – If an LLC has employees on the payroll, it must pay state employer taxes in South Carolina. These taxes are handled through South Carolina Workforce Commission.
  4. Franchise Tax Report – In South Carolina, the LLCs submit the form of a Franchise Tax Report to the South Carolina Department of Revenue.

Federal Tax Classifications

When LLCs was recognized as one of the types of Business Corporations, IRS did not create a new tax classification just for the LLC. LLCs were allowed to choose from the current tax classifications.

State Use Tax

If you have purchased goods and items from outside of the state of SC, but using those for your business registered in SC, you are liable to pay State Use Tax. It is charged at the rate of 6% of the selling price.

State Franchise Tax

In some states, the Franchise tax is also referred to as Business Privilege Tax. It is imposed on LLCs operating in the state for having the privilege to do business there. The State of South Carolina is free from the franchise tax.

Federal Self-employment Tax

Self-employment tax is payable by all the profit holders and management who earn from the LLC. It includes all sorts of earnings you make out of the LLC. The Federal Insurance Contributions Act (FICA) is responsible for regulating the Federal self-employment taxes. FICA also manages the Medicare and Social Security benefits. The federal self-employment tax is charged at the rate of 15.3% in South Carolina currently.

Federal Income Tax

Just like the State Income, Federal Income Tax is also collected on the earnings collected from your registered LLC. The tax rate is determined by the type of LLC, profits earned, deductions and allowances applicable, and the tax bracket corresponding to the LLC.

Employee and Employer Tax

An employer is a person, partner, or any organization that has hired people to work for them. Being an LLC owner, if you have hired the staff then you are liable to file a return or deposit to the SC Department of Revenue for the taxes that have been withheld in the state.

Default LLC Tax Classification Rules

By default, the LLCs are categorized as below (In both the categories, separate filing of income is not required):

Disregarded Entity (Single-Member LLC)  

A single-member LLC is usually disregarded from the taxes. Hence a single-member LLC is also called a disregarded entity. Under the U.S. tax law, it is assumed that a single-member LLC is owned by an individual (& not by another LLC), so the U.S. tax law levies rules on it as a Sole Proprietor. Single-member LLC’s owner (Sole Proprietor) has to report all the income of the LLC via his own income tax return.

Sole Proprietorship Taxes

As mentioned earlier, the single owner of the LLC is treated as the Sole proprietor of the LLC & has to file the Self-Employment Tax on all of the LLC’s earnings. South Carolina does not levy State Income Tax, so a single-member LLC must file only the Federal Income Tax.

Partnership (Multi-Member LLC)

Any LLC with more than one owner is referred to as Multi- Member LLC & it is taxed as a partnership by default. Similar to the Single Owner or Single Member LLC, this LLC is also a pass-through entity. This means that the income of the LLC passes through the income of the members & they have to file taxes through their own earnings.

Partnership Taxes

Partnership or Multi-Member LLC has to pay taxes similar to the Single Member LLC. If the Partnership LLC is directly owned by individuals, it is exempted from the Franchise Tax. All the members of the Multi-Member LLC are liable to pay Self-Employment Tax & Federal Income Tax.

Options to Change Default Tax Classification

The LLCs are categorized either as sole proprietorships or as partnerships, depending on the number of members the LLC has. This is the default tax classification applicable to LLCs. However, the LLCs have an option of changing the default classification & opting to register under the following categories for taxation purposes:


An LLC can prefer to be treated as a C-corporation by filing form 8832 (the Entity Classification Election Form) with the IRS. The C-corporation is a regular corporation that is subject to corporate taxes & it is not a pass-through entity. 

C-corporation Taxes

An LLC taxed as a C-Corporation is not a pass-through entity. In a C-corporation, the members/shareholders/ owners are taxed separately. The shareholders of the C-corporation are taxed twice on the dividends that they earn. The dividends of the shareholders are taxed at the corporate level – with a Corporate Tax filed with Form 1120 & at a Shareholder level – an Income Tax filed with Form 1040. Shareholders are subjected to Federal Income Tax.


The S-Corporation is the most common type of corporate structure used by small businesses. It was created to provide corporations with limited liability protection while maintaining the benefits of being a separate legal entity. An LLC can prefer to be treated as S-Corporation by filing Form 2553. S-corporations are small business corporations, that choose to pass through the corporate income, losses, deductions, & credits to the shareholders for the purposes of Federal Taxes.

S-corporation Taxes

An S-Corporation is similar to an LLC except that it is treated by the IRS as a corporation for tax purposes. S-Corps do pay corporate income taxes; however, they are still considered disregarded entities for federal tax purposes.

Like an LLC, an S-Corp reports its annual earnings on a separate Schedule E on the member’s personal account. An S-Corp is treated by the IRS much like a partnership for tax purposes. Unlike Partnership, in S Corporation,  the shareholders are required to pay Federal Self Income tax on their share of the company’s profits.

Choosing a Classification for Your LLC

In terms of owners’ protection against liability, perpetual existence, & savings in Taxation, Both LLCs (Limited Liability Companies) & Corporations are very much alike. However, with regard to formalities, Taxation, & capital, LLCs & Corporations differ in South Carolina. 


Both LLCs and Corporations provide liability protection to their owners. The LLC provides protection against inside liability (towards the employee) & outside liability (towards the creditor). The Corporation usually provides only the inside liability. 

Tax Classification Flexibility

For taxation purposes, an LLC has a choice of being treated as a sole proprietorship, Partnership or C-corporation or S-corporation. A corporation can choose to be treated only as C or S Corporation.


As mentioned earlier, the LLC can choose to be treated as a corporation; the Corporation does not have the option of being treated as the LLC. A South Carolina LLC is subjected to Franchise tax, Federal Income Tax, Sales & Use Taxes & State Employment Taxes (for LLCs that have employees)

A regular corporation or a C- Corporation is subjected to corporate tax, which can be filed through Form 1120 every year. The shareholders have to pay the Income-tax, only when they receive dividends from the Corporation. These dividends are taxed twice at the corporate level (on a corporate form)& at the shareholder level (on shareholder form).

An S- Corporation in LLC is not subjected to corporate taxes. But the shareholders are subjected to Taxation – even if they do not receive any dividends. A member of a South Carolina S-corporation has to pay Federal Self employment Tax only on his salary; any other profits that he makes through the LLC are not subject to the 15.3% Self Employment Tax.

How Do LLCs Pay Taxes in South Carolina

Any LLC operating in South Carolina is liable to pay 2 kinds of taxes- state taxes as well as federal taxes.

Whether you’re starting an LLC in South Carolina or want to expand to a new state, you’ll need to understand how it pays taxes. South Carolina is a state that requires LLCs to pay taxes, though it doesn’t have a separate state tax identification number (EIN). In addition to the state tax, you’ll also need to pay federal taxes. This can be done either online or by mail. A professional tax preparer can help you with your filing.

An LLC is a business structure that combines the benefits of a corporation and a partnership. It offers owners limited liability for their business debts, while allowing them more flexibility in managing regulatory matters. It also allows them to avoid double taxation and enjoy more favorable tax treatment. In order to form an LLC, you’ll need to form a company name, form the Articles of Organization, and appoint a registered agent.

The first step to forming an LLC in South Carolina is to register with the state. This can be done online, by mail, or on paper. You’ll need to provide some information about your business, such as your name, address, and contact information. You may also want to provide a certificate of authority, which is a legal document that grants you the authority to operate the LLC. If you don’t provide this information, the state may not allow you to register.

You may also need to obtain a federal tax identification number (EIN) if you plan to hire employees. The EIN is a nine-digit number assigned by the Internal Revenue Service. This number is similar to a social security number and identifies your business to state and federal tax authorities. It also acts as a tax identification number for your business accounts with most banks. If you have employees, you’ll also need to file a federal employer tax return with the IRS.

Depending on the size and structure of your LLC, you may be required to pay state and federal income taxes. Typically, an LLC pays a flat 5% of net income in state taxes. The federal rate is 15%. In addition, if you hire employees, you’ll have to withhold taxes from their paychecks. You may also have to pay a state unemployment insurance tax. A professional tax preparer can help you figure out how much tax you’ll owe.

Once you’ve established an LLC, you’ll need to register with the Department of Revenue (DOR). You can file your forms online, by mail, or on paper. You’ll need to provide a physical address, as well as a name and address for your registered agent. A registered agent is a person who will accept legal mail for your business. You may also have to pay an annual registered agent service fee.

You will also need to submit periodic sales tax returns to the Department of Revenue. You can submit your sales tax return online, by mail, or on paper. Your business will also be required to pay the South Carolina Electric Power Tax, which is based on the number of kilowatts of electricity you sell to customers. It’s also possible that counties may impose a local sales tax.
