How the S-Corp tax savings work
LLC / Sole Proprietor (default)
As a sole prop or single-member LLC, 100% of your net business income is subject to self-employment tax (15.3% up to $176,100, then 2.9% above). On $100K net income, that is approximately $14,130 in SE tax — before any income tax.
S-Corp election
By electing S-Corp status, you split income into (1) a W-2 salary and (2) a distribution. FICA (15.3%) applies only to the salary. The distribution passes through free of SE tax — saving 15.3% on that portion of income.
Example: $100K net income, $60K salary
| Tax | LLC (no S-Corp) | S-Corp | Difference |
|---|---|---|---|
| Self-Employment / FICA tax | $14,130 | $9,180 | −$4,950 |
| Annual compliance cost | $0 | $2,000 | +$2,000 |
| Net first-year savings | — | — | $2,950 |
Figures use 2025 rates. SS wage base $176,100. Compliance cost is an estimate.
