LLC vs S Corp: Differences, Taxes, and How to Choose

A limited liability company, or LLC, is a business entity formed under state law.

LLCs can have one or more owners, known as members. They generally offer flexible management and fewer formal requirements than corporations.

For federal tax purposes, the IRS does not have a separate “LLC” tax classification. A single-member LLC is generally treated as a disregarded entity by default, while a multi-member LLC is generally treated as a partnership. An LLC can also elect corporate taxation.

This flexibility is one reason LLCs are widely used by small businesses.

An S corporation is a tax status, not a separate state-created business entity.

A qualifying corporation can elect S corporation taxation. An eligible LLC can also make the election. The LLC remains an LLC under state law, but the IRS treats it differently for federal tax purposes.

S corporations generally use pass-through taxation. Business income and other tax items pass through to the owners and are reported on their individual tax returns.

S corporations also have specific ownership and tax rules that must be followed.

The default federal tax treatment of an LLC depends on the number of owners.

A single-member LLC is generally taxed as a disregarded entity. Business income and expenses are generally reported on the owner’s federal tax return.

A multi-member LLC is generally taxed as a partnership. The business generally passes income and other tax items through to its members.

An LLC can also elect to be taxed as an S corporation by filing the required IRS election.

An LLC taxed as S corp keeps its LLC legal structure while using S corporation tax treatment.

This means the owner does not have to create a separate S corporation just to use S corporation taxation. If the LLC qualifies and makes the election, it remains an LLC under state law.

One important difference is how owner compensation is handled.

An owner who works for an S corporation generally needs to receive reasonable compensation for services. The business may then make additional distributions when appropriate. Wages are subject to employment taxes, while qualifying distributions are generally treated differently for employment tax purposes.

This can make S corporation taxation worth considering for some established LLCs, but it also adds payroll and reporting responsibilities.

When comparing S corp vs LLC taxes, it is important to understand that a default LLC and an LLC taxed as an S corporation can have different tax treatment.

With a default LLC, business income generally passes through to the members. Depending on the LLC’s tax classification and the owner’s circumstances, income may be subject to self-employment tax.

With S corporation taxation, an owner who provides services generally receives wages, and additional qualifying business income may be distributed separately. The wage portion is subject to employment taxes.

This does not mean an S corporation automatically results in lower taxes. The outcome depends on factors such as business income, reasonable compensation, payroll costs, deductions, and state tax rules.

An eligible LLC can use Form 2553, Election by a Small Business Corporation, to request S corporation tax treatment.

The IRS has specific requirements for businesses making the election. These include rules about the type of entity, shareholders or members, ownership, and stock structure.

The timing of the election also matters. Businesses should review the IRS filing requirements and applicable deadlines before submitting Form 2553.

If the election is made correctly, the LLC can continue operating under its existing state-law structure while using S corporation taxation for federal tax purposes.

One reason business owners consider an S corporation election is the potential treatment of owner compensation and distributions.

A qualifying S corporation can generally pass business income through to its owners instead of paying regular federal corporate income tax. Owners who work for the company generally receive wages, while other qualifying profits may be distributed separately.

This structure may reduce the amount of business income subject to employment taxes in some situations.

However, the IRS requires reasonable compensation for shareholder-employees who provide services. An owner cannot simply classify all business income as distributions to avoid employment taxes.

The potential tax benefit should be weighed against the added administration of payroll, tax filings, and recordkeeping.

A tax professional can review your specific numbers and circumstances before you make the election.

An LLC and an S corporation can differ in how ownership and management work.

LLC owners are called members. The LLC can generally be managed by its members or by appointed managers. The operating agreement sets many of the internal rules.

An S corporation can be organized as a corporation or can be an LLC that elects S corporation taxation. S corporations must follow specific federal tax rules concerning shareholders, ownership, and stock.

This means the business’s legal structure still matters even after an S corporation election.

Not every business can elect S corporation taxation.

The IRS generally requires an S corporation to be a domestic entity, have no more than 100 shareholders or members, and have only one class of stock. Certain types of shareholders are also restricted.

An LLC considering the election should check these requirements before filing.

Failing to meet the requirements can affect the business’s S corporation status and tax treatment.

An LLC can provide a flexible legal structure with different federal tax options. S corporation status can provide a different way to handle taxation and owner compensation for an eligible business.

For many business owners, the real decision is not whether to form an LLC or an S corporation. It is whether an existing or planned LLC should elect S corporation taxation.

Your business income, ownership, payroll, state requirements, and future plans all matter.
