Single-Member LLC Tax Treatment and S-Corp Election Strategy

A single-member LLC provides liability protection while maintaining pass-through taxation. Understanding when and how to elect S-corp status can unlock significant self-employment tax savings.

Same tax treatment as a sole proprietorship by default. The IRS treats a single-member LLC as a "disregarded entity." You still report on Schedule C and pay self-employment tax on all net profit -- exactly like a sole proprietor. The LLC changes your legal protection, not your tax bill.

You can elect S-corp taxation without forming a corporation. By filing Form 2553, your LLC can be taxed as an S-corporation. This lets you split income into salary (subject to employment tax) and distributions (not subject to SE tax), potentially saving thousands per year. The LLC remains an LLC under state law.

Liability protection requires maintenance. The LLC shield only holds if you keep business and personal finances separate -- dedicated bank account, no commingling of funds, and a formal operating agreement. Courts "pierce the veil" of LLCs that are treated as alter egos of their owners.

State fees vary significantly. Annual LLC fees range from $0 (many states) to $800+ (California franchise tax). Some states impose gross receipts taxes on LLCs regardless of profit.

The tradeoff: An LLC adds liability protection and future tax flexibility, but the default tax treatment is identical to a sole proprietorship. Without an S-corp election, you are paying the same SE tax with added state compliance costs.
