S-Corp vs LLC: Which Structure is Right for Your Business?
One of the most common questions we get is: "Should I be an S-Corp?" The answer, as always in tax, is: "It depends." The S-Corp election can save tens of thousands in self-employment taxes, but it comes with administrative complexity and costs. Here's how to know if it makes sense for you.
The Self-Employment Tax Problem
As a single-member LLC (or sole proprietor), you pay self-employment tax—15.3% for Social Security and Medicare—on all your net profit. If your business nets $150,000, you're paying $22,950 in self-employment tax before income tax even begins.
With an S-Corp, you split your income into two categories: "Reasonable Salary" (subject to payroll and self-employment tax) and "Distributions" (subject only to income tax, not self-employment tax). This is where the savings come from.
The S-Corp Savings Calculation
Example: You net $150,000 in profit. As an LLC, you pay 15.3% SE tax on the full amount = $22,950.
As an S-Corp, you pay yourself a $70,000 salary (reasonable for your industry and role) and take $80,000 as distributions. You pay SE tax only on the $70,000 salary = $10,710. Tax savings: $12,240 per year.
The IRS requires you pay yourself a "reasonable salary" for the work you do. Set it too low and you risk audit adjustments. Industry standards matter—use salary surveys and CPA guidance to defend your compensation split.
The Trade-Off: Administrative Burden
S-Corps come with more complexity and costs:
Payroll Requirements: You must run payroll for yourself (and any employees), file quarterly payroll tax returns, and handle W-2s at year-end. Payroll services cost $500-2,000 annually depending on complexity.
Separate Tax Return: S-Corps file Form 1120-S, a separate business return, in addition to your personal 1040. Expect to pay your CPA an extra $800-2,000 for this return.
State Compliance: Some states charge annual franchise taxes or fees for S-Corps. California charges a minimum $800 franchise tax, for example.
Stricter Rules: S-Corps have limitations on ownership structure (only individuals, certain trusts, and estates can be shareholders; max 100 shareholders), single class of stock, and U.S. residency requirements.
The Sweet Spot: $60k-$80k Net Profit
Generally, once your business nets around $60k-$80k in profit, the tax savings from the S-Corp election start to outweigh the additional administrative costs and complexity. Below that threshold, the simplicity and lower cost of an LLC is usually preferred.
Above $100k in net profit, the S-Corp election becomes increasingly attractive. At $200k+ in net profit, the annual savings can be $20k-30k—making the administrative burden a minor inconvenience compared to the tax benefits.
Making the Election
The S-Corp election is made by filing Form 2553 with the IRS. If you want it effective for the current tax year, you must file by March 15 (or within 2 months and 15 days of forming your entity). Miss the deadline and you're stuck with LLC treatment until next year.
Most business owners elect S-Corp treatment for an existing LLC rather than forming a separate S-Corporation entity. This preserves the liability protection and simplicity of the LLC while gaining the tax benefits of S-Corp treatment. It's called an "S-Corp election" or "LLC taxed as S-Corp."
When to Stay an LLC
Stick with standard LLC treatment if your profit is under $60k, you have irregular income (some years profitable, some not), you want maximum flexibility in ownership structure, or you plan to have significant losses in the near term (S-Corps have stricter loss limitation rules).
Also, if you're a real estate investor primarily holding rental properties, S-Corp treatment usually doesn't make sense. Rental income isn't subject to self-employment tax anyway, so there's no savings. S-Corps work best for service businesses, consultants, agencies, and active business operations.
The Bottom Line
Run the numbers with your CPA before making the election. Calculate your reasonable salary, estimate your payroll and tax prep costs, and compare total tax liability under both structures. For most businesses netting $80k+, the S-Corp election saves significant money despite the added complexity.
Just remember: the election is a tax classification choice, not a change in legal entity. Your liability protection remains the same. You're simply optimizing how the IRS taxes your business income.
