In general, a Limited Liability Company (LLC) in South Carolina does not pay any taxes like corporations and other business structures. It has a pass-through taxation instead of business or corporate tax. Besides, the LLC tax structure includes state and federal mandatory taxes. LLCs are required to choose the tax structure at the time of filing the company.

IRS (Internal Revenue Service) allows an LLC in South Carolina to choose its preferred classification of tax at the beginning of the LLC filing. For example, 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, everyone certainly wants to opt for the most beneficial one. On this page, LLCBuddy editors shared all about the tax structure in South Carolina LLC.

How Does Taxation Work in a South Carolina LLC

For an LLC in South Carolina, the tax structure is very simple and flexible. First of all, every LLC has the advantage of a pass-through taxation. On the other hand, an LLC can choose the desired tax structure at the time of formation. There are two ways an LLC can be taxed,

As a Sole Proprietorship

A single-member LLC is usually considered a sole proprietorship company. Hence, by default, it is taxed as a sole proprietorship. 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. A single-member LLC’s owner (Sole Proprietor) has to report all the income of the LLC via their own income tax return.

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.

As a Partnership

Any LLC with more than one owner is referred to as a 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 or Multi-Member LLC has to pay taxes similar to those of the Single-Member LLC. If the Partnership LLC is directly owned by individuals, it is exempt from the Franchise Tax. All the members of the Multi-Member LLC are liable to pay Self-Employment Tax & Federal Income Tax.

Pass-through Taxation for South Carolina LLC

A Limited Liability Company (LLC) is a form of business structure that consists of members and/or managers (owners). The biggest advantage of an LLC in South Carolina is the pass-through taxation. The limited liability company does not pay any federal income taxes based on the revenue of the company. Instead, the tax liability passes through to each member of the LLC. Furthermore, the members will have to pay individual income tax based on their income.

Both for a single-member LLC and a multi-member LLC in South Carolina, the tax burden passes through to the member(s). In other cases, if an LLC chooses to be taxed as a Corporation, the LLC will have to pay federal income tax based on its revenue and profit. There is no pass-through taxation for C-Corp and S-Corp.

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:

C-Corporation

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 subject to Federal Income Tax.

S-Corporation

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 an 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.

LLC Taxes to be Paid in South Carolina

Any LLC that is registered in the state of South Carolina is liable to pay the following types of taxes that are levied by the State government:

State Income Tax

Income tax is paid on the earnings obtained by your business. The state Income tax of South Carolina is in accordance with the Federal Income Tax laws. It means that all sorts of exemptions and allowances on federal tax returns are accepted in the state of South Carolina. The current rate of income tax in SC is up to 7%.

State Sales Tax

For an LLC that is involved in selling products and services in the state of South Carolina, it is required to pay the Sales Tax. In SC, sales tax is imposed on most kinds of retail sales. Sales tax is charged at a rate of 6% in the whole of the state. However, you may be required to pay an additional 1% local tax imposed by counties.

State Use Tax

If you have purchased goods and items from outside the state of SC, but are 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 the 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 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. The employees are required to file the tax return, regardless of whether they have withheld the payroll tax or not.

Other Taxes

For operating a business in the state of South Carolina, you are liable to pay some exclusive taxes if you are dealing in certain products and services.

Electric Power Tax

This tax is payable by an LLC that is involved in the resale of electric power, as well as by any public utility department that sells electricity to consumers. For each kilowatt-hour of electric power sold, charges equal to one mill (0.0005) are payable. For more details, please visit- Electric Power Tax.

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 to 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 the South Carolina Workforce Commission.
  4. Franchise Tax Report – In South Carolina, the LLCs submit the Franchise Tax Report to the South Carolina Department of Revenue.

Federal Tax Classifications

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

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.

Liabilities

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, C-corporation, or S-corporation. A corporation can choose to be treated only as a C or S Corporation.

Taxation

As mentioned earlier, the LLC can choose to be treated as a corporation; the Corporation does not have the option of being treated as an LLC. A South Carolina LLC is subject 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 subject 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 an LLC is not subject 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

LLCs are a popular choice for small businesses due to their flexibility and legal protections. However, when it comes to taxes, LLCs are treated differently from sole proprietorships and corporations. In South Carolina, LLCs are pass-through entities when it comes to federal taxes, meaning the profits and losses of the business are passed through to the owners’ individual tax returns.

When it comes to state taxes, LLCs in South Carolina are treated similarly to other types of businesses. LLCs must file a state tax return and pay state taxes on any income generated within the state. The state tax rate for LLCs in South Carolina varies depending on the amount of income earned by the business.

It’s important for LLC owners in South Carolina to keep accurate records of their business income and expenses in order to properly file their state tax returns. All financial transactions related to the business should be well-documented and maintained throughout the year to ensure compliance with tax laws.

LLCs in South Carolina are also subject to an annual reporting requirement with the South Carolina Secretary of State. This annual report must be filed by the designated due date in order to maintain good standing with the state. Failure to file the annual report on time can result in penalties and could even lead to the dissolution of the LLC.

In addition to state taxes, LLCs in South Carolina may also be subject to local taxes depending on the location of the business. It’s important for LLC owners to research and understand the local tax requirements in order to avoid any potential compliance issues.

When it comes to paying taxes as an LLC in South Carolina, it’s essential for business owners to seek guidance from a qualified tax professional. Tax laws can be complex, and navigating them on your own can be challenging.

By working with a tax professional, LLC owners can ensure they are in compliance with all state and local tax requirements. A tax professional can also help identify any potential tax deductions or credits that could help reduce the tax liability of the business.

Overall, understanding how LLCs pay taxes in South Carolina is crucial for business owners to effectively manage their finances and ensure the continued success of their businesses. By staying informed and seeking guidance from professionals, LLC owners can navigate the tax landscape with confidence and peace of mind.

In Conclusion

Every Tax classification has its own set of benefits & restrictions. Every state will have different taxation rules for each of the categories of business corporations. Depending on the objective of formation of the business entity (Eg, to avoid dual Taxation- one can choose S Corporation, for more flexibility, one can choose the LLC format). It is essential to understand the taxing structure of each country & each Classification to decide how you wish to treat your LLC.
