Answer (2026): An S-Corp election can reduce self-employment taxes by splitting your business income between a reasonable salary (subject to payroll tax) and distributions (not subject to payroll tax). The savings depend on your net profit level, state rules, and compliance costs. Use the calculator below to estimate your specific gap, then follow the decision framework to determine if the switch is worth the added complexity.
Context: This guide is for self-employed professionals and business owners earning $80K+ in net profit who are currently operating as a sole proprietorship or single-member LLC and wondering whether an S-Corp election makes financial sense.
Last reviewed: September 23, 2026.
- If you are a sole proprietor or single-member LLC paying self-employment tax on all your business profit
- If your net profit exceeds $80,000 and you haven't evaluated the S-Corp election
- If you've heard "switch to an S-Corp" from peers but haven't run the numbers for your specific situation
This guide is likely relevant if at least two statements are true:
- Your Schedule SE self-employment tax exceeded $10,000 last year.
- You operate a service-based business (consulting, coaching, freelance, professional services).
- You haven't compared your current payroll tax burden against what it would be as an S-Corp.
The core math is straightforward. As a sole proprietor or single-member LLC, you pay self-employment tax (Social Security + Medicare) on your entire net profit. As an S-Corp, you pay payroll tax only on your reasonable salary. The remaining profit flows through as distributions, which are not subject to payroll tax.
The formula:
- LLC payroll tax: Net profit x 15.3% (up to the Social Security wage base of $176,100 in 2026, then 2.9% Medicare on the remainder, plus 0.9% Additional Medicare Tax on wages above $200K)
- S-Corp payroll tax: Reasonable salary x 15.3% (same thresholds)
- Estimated savings: The difference, minus S-Corp compliance costs ($1,500-$4,000/year for payroll, additional tax return, and state fees)
The S-Corp Tax Savings Calculator runs this math with current 2026 tax rates and shows you the estimated annual savings after accounting for typical compliance costs.
What it calculates: The payroll tax difference between LLC and S-Corp at your profit level, factoring in a reasonable salary estimate and typical compliance costs.
Use it when: You want a quick estimate of whether the S-Corp election is worth investigating further.

What it calculates: A defensible reasonable salary range based on your role, industry, geography, and hours worked. The IRS requires S-Corp owner-employees to pay themselves a reasonable salary before taking distributions.
Use it when: You've decided the S-Corp makes sense and need to set your salary. This is the number the IRS cares most about.

What it shows: Whether you're still within the filing window for Form 2553 (S-Corp election). The deadline is 2 months and 15 days after the start of the tax year. Miss it and you wait until next year (unless you qualify for late relief).
Use it when: You've run the numbers and decided to elect. Timing matters.

The S-Corp is not universally better than an LLC. It adds complexity and cost. The decision depends on three variables:
The payroll tax savings grow with income, but compliance costs are fixed. Below roughly $60K-$80K in net profit, the savings may not justify the added administrative burden.
| Net Profit | Estimated Annual Savings | Likely Worth It? |
|---|
| $50,000 | $2,000-$3,000 | Maybe not. Compliance costs eat most of the savings |
| $80,000 | $4,000-$6,000 | Worth evaluating with a CPA |
| $120,000 | $7,000-$10,000 | Strong case for most service businesses |
| $200,000 | $10,000-$15,000 | Clear case unless state rules penalize S-Corps |
| $300,000+ | $12,000-$18,000 | Almost always worth it (savings plateau above Social Security wage base) |
These are estimates. Run the calculator with your actual numbers.
Not all states treat S-Corps the same:
- California charges a 1.5% franchise tax on S-Corp net income (minimum $800). This can cut into savings for lower-profit businesses.
- New York City does not recognize S-Corp status. You'll pay the full corporate tax.
- Texas applies its franchise (margin) tax to S-Corps.
- Florida, Nevada, Wyoming, Texas have no state income tax, so S-Corp savings are purely federal.
See our state-by-state S-Corp analysis for specific breakdowns by state and profession.
An S-Corp requires:
- Payroll processing ($500-$1,500/year through services like Gusto or ADP)
- Separate S-Corp tax return (Form 1120-S). CPA fees typically $1,000-$2,500
- Quarterly payroll tax deposits
- State franchise fees (varies by state)
- Reasonable compensation documentation
Total annual overhead: $1,500-$4,000. If your estimated savings don't clear this bar with room to spare, the LLC is simpler.
The qualified business income deduction can be worth up to 20% of a pass-through business's qualified income, and it's now permanent. It isn't automatic, and it interacts with every S corporation salary decision. Five checks, in order:
- Entity type. The deduction applies to pass-through income: S corporations, partnerships, and sole proprietorships. Your salary from your own S corporation doesn't count as qualified business income; the business's remaining profit does.
- Your income against the 2026 thresholds. Below $403,500 of taxable income for joint filers ($201,750 for most others), the limits below don't apply. They phase in fully by $553,500 ($276,750).
- Specified service businesses. Above the thresholds, businesses in fields such as health, law, accounting, consulting, and financial services lose the deduction as income rises through the phase-in range.
- Wages and property. Above the thresholds, the deduction for other businesses is also limited by the W-2 wages the business pays and its qualified property. Raising your salary can help this limit while shrinking the qualified income itself, which is why the salary decision needs a projection, not a rule of thumb.
- The new minimum. Starting in 2026, an otherwise eligible taxpayer with at least $1,000 of qualified business income from businesses they materially participate in gets a deduction of at least $400.
If income crossed a threshold this year, assume the deduction changed and have your CPA recompute it with the current Form 8995 or 8995-A instructions. The QBI deduction calculator gives a first estimate.
The IRS audits S-Corp owner compensation. A software consultant earning $200K in distributions with a $30K salary is a red flag. Use the Reasonable Salary Calculator to find a defensible range, and document how you arrived at the number.
The Section 199A qualified business income (QBI) deduction is based on the S corporation's qualifying profit after your reasonable compensation, and the salary itself doesn't count as qualified business income. A higher salary reduces your QBI deduction. For some income levels, the QBI deduction loss partially offsets the payroll tax savings. See how the QBI deduction fits in above for the 2026 thresholds.
Form 2553 must be filed within 2 months and 15 days of the start of the tax year. For calendar-year businesses, that's March 15. Miss it and you wait until next year, unless you qualify for late-election relief under Revenue Procedure 2013-30.
Some states charge additional S-Corp taxes, fees, or don't conform to federal S-Corp treatment. Check with your CPA before assuming federal savings translate to your state.
Before making the S-Corp election, confirm:
- Net profit consistently exceeds $80,000 (not a one-time spike)
- Estimated payroll tax savings exceed compliance costs by at least $3,000
- Your state doesn't impose penalties that erase the federal savings
- You can document a defensible reasonable salary
- You understand the QBI deduction interaction at your income level
- You have a CPA or tax professional to handle the additional filing requirements
- What would a defensible reasonable salary be for my role and industry?
- How does the S-Corp election interact with my QBI deduction?
- What are the state-specific costs and rules for an S-Corp in my state?
- Should I elect mid-year or wait for the start of next tax year?
- Is an S-Corp still the right structure if my income fluctuates year to year?
- Run the numbers. Use the S-Corp Tax Savings Calculator with your actual net profit. If estimated savings are under $3,000 after compliance costs, the LLC is probably simpler.
- Check your state. Review the state-by-state S-Corp analysis for your state's specific rules and fees.
- Talk to your CPA. Bring the calculator output and your reasonable salary estimate to a conversation with your tax professional. They can factor in QBI, state rules, and your specific entity structure.
