LLC vs S-Corp: How Much Can You Save in Self-Employment Tax?

The Self-Employment Tax Problem

Self-employed individuals — freelancers, consultants, and sole proprietors — pay self-employment (SE) tax of 15.3% on their net business income. This covers both the employee and employer portions of Social Security and Medicare taxes. An employee earning $100,000 pays 7.65% in FICA taxes (the other 7.65% is paid by the employer). A self-employed person earning the same amount pays the full 15.3% — an additional tax burden of approximately $7,650 compared to being an employee. The S-Corp election is a legal strategy to reduce this SE tax burden.

How the S-Corp Strategy Works

When you elect S-Corp status for your LLC or corporation, your business income is split into two components: a reasonable salary you pay yourself as an employee, and a profit distribution paid to you as the owner. SE tax applies only to the salary portion — the distribution is exempt from SE tax. If your business earns $120,000 and you pay yourself a $60,000 salary, SE tax applies only to the $60,000 salary ($9,180 in SE tax) rather than the full $120,000 ($18,360 in SE tax). The savings is approximately $9,180 — before accounting for S-Corp setup and maintenance costs.

The Reasonable Salary Requirement

The IRS requires S-Corp owner-employees to pay themselves a "reasonable" salary — compensation comparable to what someone would pay a third party to perform the same services. The IRS scrutinizes S-Corps where owners pay themselves very low salaries to minimize SE tax. A general guideline used by many tax professionals is that salary should be approximately 40% of net business income, with a minimum typically around $40,000-50,000 for a full-time professional. Setting an unreasonably low salary is a red flag for IRS audit and can result in the IRS reclassifying distributions as wages — plus penalties and interest.

When Does S-Corp Make Financial Sense?

The S-Corp strategy has fixed setup and ongoing costs that must be justified by the SE tax savings. Setup costs include state filing fees ($50-500), operating agreements, and potentially attorney or accountant fees — total approximately $500-1,500. Ongoing costs include separate business bank accounts, payroll processing (required for the salary component), additional accounting fees for the S-Corp tax return (Form 1120-S), and state annual report fees. A commonly cited threshold is net business income of $50,000-60,000 per year — below this level, the SE tax savings may not cover the additional administrative costs.

Frequently Asked Questions

What is the process for electing S-Corp status?
File IRS Form 2553 (Election by a Small Business Corporation) within 75 days of the start of the tax year you want the election to be effective, or by March 15 of the following year for calendar year filers. Many states also require a separate state S-Corp election.

Can a single-member LLC elect S-Corp status?
Yes. A single-member LLC must first be treated as a corporation by filing Form 8832, then elect S-Corp status with Form 2553. Alternatively, Form 2553 can accomplish both steps if filed correctly.

How does the S-Corp affect retirement contributions?
S-Corp salary is W-2 income, which enables contributions to Solo 401(k) and SEP-IRA based on W-2 earnings. The total contribution limits differ from self-employed contributions — consult a CPA for optimization.

Does S-Corp status affect the QBI deduction?
Yes. The Qualified Business Income (QBI) deduction of up to 20% applies to S-Corp distributions, not to W-2 wages. For high-income service businesses that are "specified service trades," the QBI deduction phases out above certain income thresholds regardless of entity type.

What states do not recognize S-Corp status?
Most states recognize federal S-Corp elections, but some states (including New York City and Washington DC) impose additional taxes on S-Corps. A few states have their own S-Corp requirements. Verify your state's treatment with a local tax professional.

Can I switch back from S-Corp to LLC later?
Yes, but there are restrictions. S-Corp elections can be revoked voluntarily, but the IRS generally requires 5 years to pass before a new S-Corp election can be made. Terminating S-Corp status has tax implications — consult a CPA before making this decision.
