LLC vs S-Corp Tax Calculator 2026 — How Much Could You Actually Save?
Last updated: June 20269 min readIncludes 2026 SE tax rates
If you're a freelancer or solopreneur earning $60,000 or more, you've probably heard that electing S-Corp status could save you thousands in taxes every year. But the math isn't always obvious — and getting it wrong in either direction costs real money. This calculator shows you the exact numbers at your income level, and explains when S-Corp makes sense and when it doesn't.

How the LLC vs S-Corp Tax Difference Actually Works
As a single-member LLC, all of your net business income flows through to your personal tax return as self-employment income. You pay self-employment (SE) tax at 15.3% on the first $176,100 of net earnings (2026 rate), plus 2.9% Medicare on everything above that. On $100,000 net income, that's roughly $14,130 in SE tax alone — before income tax.
When you elect S-Corp status for your LLC, the structure changes. You must pay yourself a "reasonable salary" as a W-2 employee. Only the salary portion is subject to payroll taxes (equivalent to SE tax). The remaining profit can be taken as an owner distribution — which is not subject to payroll tax. That's where the savings come from.
💡
Simple example at $100,000 net income: LLC pays SE tax on the full $100k ≈ $14,130. S-Corp with $60k salary pays payroll tax only on $60k ≈ $8,478. The $40k in distributions saves roughly $5,652 in tax. Minus ~$2,500 in S-Corp compliance costs = net savings ≈ $3,152/year.
The Break-Even Point: When S-Corp Starts Making Sense
S-Corp status comes with real ongoing costs: payroll software, a separate business tax return (Form 1120-S), and typically a CPA who knows S-Corp compliance. These costs typically run $2,000–$4,500/year. Below certain income levels, these costs exceed the tax savings.

⚠️
The break-even isn't universal: It depends on your state, your CPA's fees, the payroll software you use, and your reasonable salary amount. The calculator below uses your specific inputs to give you a precise number.
The Reasonable Salary Rule — And Why It Matters
The IRS requires S-Corp owners who work in the business to pay themselves a "reasonable salary" before taking distributions. This is the most important variable in the S-Corp calculation — and the most commonly misunderstood.
Too low: IRS audit risk. The IRS looks for W-2 salaries that are artificially depressed to minimize payroll taxes. Getting caught means back taxes, interest, and penalties.
Too high: You eliminate the benefit. If your salary equals your net income, there's nothing left for distributions — no savings.
The general rule: Most CPAs recommend 40–60% of net profit as a starting point. The IRS benchmark is what you'd pay a market-rate employee doing the same work.
The Real Compliance Costs of S-Corp
Many guides only mention the tax savings. Here are the full annual costs to factor in:
S-Corp tax return (Form 1120-S): $800–$2,000/year via CPA
State-level S-Corp fees: Varies — California charges $800 minimum; some states don't recognize S-Corp
Additional bookkeeping: $0–$1,500/year depending on complexity
Your time: Quarterly payroll deposits, record-keeping — estimated 3–5 hours/month
State-Level Considerations
Federal SE tax savings are consistent across states, but your net benefit varies significantly depending on where you operate:
California: Charges a 1.5% state S-Corp franchise tax on net income (minimum $800). At $100k income, adds ~$1,500 in state costs. Still worth it at higher incomes.
New York: Has its own S-Corp tax treatment. Consult a NY-specific CPA before electing.
Texas, Florida, Nevada: No state income tax. S-Corp election is purely a federal play — math is cleanest here.
Most other states: Generally follow federal treatment. Check your state's specific S-Corp rules.

Technically yes — you can elect S-Corp tax treatment for a C-Corp or directly as a qualified subchapter S trust. However, for most solopreneurs, the standard path is: (1) form an LLC, (2) file Form 2553 to elect S-Corp tax treatment for that LLC. This gives you liability protection from the LLC structure plus the tax benefits of S-Corp status.
To have S-Corp status apply to the current tax year, you must file Form 2553 by March 15 of that year (or within 2 months and 15 days of the start of the tax year for new businesses). If you miss the deadline, you can still file and request relief for a late election — the IRS grants this frequently for businesses that acted reasonably. You can also elect for the following year at any time during the current year.
The IRS requires that S-Corp owner-employees who provide services receive a "reasonable" W-2 salary before taking distributions. Reasonable means what you'd pay a third-party employee to do the same work. The IRS uses Bureau of Labor Statistics wage data and industry benchmarks. Most CPAs recommend 40–60% of net profit as a starting framework, but the right number depends on your industry, role, and what comparable positions pay. Document your reasoning — it matters if you're ever audited.
Yes, and this is one of the underappreciated benefits. With an S-Corp, your Solo 401(k) contribution limits are based on your W-2 salary, not your total business profit. As an employee, you can contribute up to $23,500 (2026 limit) in elective deferrals, plus the business can make an employer contribution of up to 25% of your W-2 salary. Total combined limit is $70,000 in 2026. Properly structured, this can significantly reduce your taxable income beyond just the SE tax savings.
Yes, but there are restrictions. You can revoke an S-Corp election, but once revoked, you must wait 5 years before re-electing S-Corp status (unless the IRS grants an exception). The revocation must be filed with the IRS, typically by March 15 to take effect for the current tax year. This isn't a decision to make lightly — get CPA guidance before revoking.
Yes, significantly. California imposes a 1.5% franchise tax on S-Corp net income, with a minimum of $800/year. This reduces (but usually doesn't eliminate) the federal tax savings. For example, on $120,000 net income, the CA S-Corp tax would be $1,800 — still leaving substantial net savings at that income level. However, at lower incomes ($50,000–$70,000), the CA costs can make S-Corp marginal. California also has its own S-Corp qualification requirements. Always run California-specific numbers with a CA-licensed CPA.
