LLC or S Corporation for Your Business?

Reviewed October 2, 2026. General federal tax guidance; state rules and individual circumstances may differ.

An LLC is a state-law business structure. S corporation status is a federal tax election available to eligible entities. They are not interchangeable choices: an eligible LLC may elect S corporation taxation.

Does an LLC automatically lower my taxes?

No. A single-owner LLC is generally disregarded for federal income tax purposes unless it elects corporate treatment. Its owner generally remains subject to self-employment tax on business net earnings.

What changes with S corporation taxation?

There are eligibility requirements, election deadlines, separate tax filings, and payroll responsibilities. An owner who provides services must receive reasonable compensation before non-wage distributions. Potential benefits must be weighed against those costs and obligations.

Example: forming an LLC

Registering a one-owner LLC with a state does not by itself create an S corporation election. Federal tax classification and state formation are separate steps.

What should SWT review first?

Your state, ownership, expected profit, services performed, existing entity, and ability to maintain payroll and business records. There is no single profit figure that makes an S corporation right for everyone.

Can SWT form an entity in my state?

We can help create LLCs, corporations, and other entities in most states and review applicable tax elections. Tell us your state and plans so we can confirm the requirements.
