At what income level does an S-Corp make financial sense?

An S-Corp typically makes sense when your net business profit exceeds $50,000–$60,000 per year. Below this threshold, the additional accounting and administrative costs (estimated $1,500–$3,000/year for payroll processing, additional tax filings, and potentially a CPA) often exceed the SE tax savings. The break-even point varies based on your state, salary level, and accounting fees.

Q: How does an S-Corp save on self-employment taxes?

An S-Corp saves on self-employment taxes by splitting business income into two parts: a W-2 salary (subject to payroll taxes) and distributions (not subject to SE tax or payroll taxes). As an LLC sole proprietor, 100% of net profit is subject to the 15.3% SE tax. With an S-Corp, only your salary is subject to employment taxes — distributions are tax-free from SE tax, creating significant savings at higher income levels.

Q: What are the extra costs of an S-Corp?

Running an S-Corp involves additional annual costs: state registration/franchise fees ($50–$800+/year depending on state), payroll processing software or service ($500–$1,500/year), additional tax return preparation (Form 1120-S, approximately $500–$1,500 more than a Schedule C), and potentially higher CPA fees for ongoing compliance. Total additional costs typically range from $1,500 to $3,500 per year.

The biggest tax advantage of electing S-Corp status is avoiding self-employment tax on distributions. As an LLC (sole proprietor), all net profit is subject to 15.3% SE tax. With an S-Corp, you pay yourself a reasonable salary (subject to payroll taxes) and take the rest as distributions — which are not subject to SE or payroll taxes. This calculator shows your exact savings.

When Does an S-Corp Make Sense?

The S-Corp election makes financial sense when the SE tax savings exceed the additional administrative costs. Generally, this means:

Net profit above $50,000–$60,000/year — below this, extra costs often outweigh savings
You can pay yourself a defensible reasonable salary that's below your total profit
You're comfortable with payroll processing obligations (quarterly deposits, annual W-2s)
Your state doesn't impose extra franchise taxes that eliminate the savings (e.g., California's $800 minimum + 1.5% S-Corp tax)

Rule of thumb: S-Corp overhead typically costs $1,500–$3,000/year. At a 15.3% SE tax rate, you need about $10,000–$20,000 in distributions (profit above salary) to break even. That points to needing roughly $50,000+ in net profit above your salary.

LLC vs S-Corp: Frequently Asked Questions

An S-Corp saves on SE taxes by splitting business income into two parts: a W-2 salary (subject to payroll taxes) and distributions (not subject to SE tax or payroll taxes). As an LLC sole proprietor, 100% of net profit is subject to the 15.3% SE tax. With an S-Corp, only your salary is subject to employment taxes — distributions are free from SE tax, creating significant savings at higher income levels.

The IRS requires S-Corp owner-employees to pay themselves a "reasonable salary" comparable to what similar businesses would pay for the same services. There is no fixed percentage rule, but the salary must reflect fair market compensation for your role and industry. Paying an unreasonably low salary to maximize distributions is a red flag for IRS audits. Use our S-Corp Salary Calculator to estimate a defensible salary range for your profession.

Yes. An existing LLC can elect to be taxed as an S-Corp by filing IRS Form 2553. The election must generally be filed by March 15 of the tax year you want it to take effect (for calendar year filers), or within 75 days of forming the entity. Late election relief is available in some circumstances. The LLC retains its legal structure under state law — only the federal tax treatment changes. This is sometimes called an "LLC taxed as an S-Corp."
