How the LLC vs S-Corp Tax Calculator Works
The Core Difference: SECA vs FICA
By default, a single-member LLC is taxed as a sole proprietorship. This means 100% of your net profit (after the 7.65% employer-equivalent adjustment) is subject to the 15.3% Self-Employment Contributions Act (SECA) tax. That covers Social Security (12.4%) and Medicare (2.9%).
When you file Form 2553 to elect S-Corp taxation, the IRS splits your profit into two buckets:
- W-2 Salary: Subject to the same 15.3% FICA payroll tax (split between you and the S-Corp).
- Distributions: Not subject to SECA/FICA tax. Only subject to federal and state income tax.
Example: $150,000 net profit, 50% reasonable salary ($75,000). LLC pays 15.3% on ~$138,525 = $21,195 in SECA tax. S-Corp pays 15.3% on $75,000 = $11,475 in FICA tax. S-Corp saves $9,720 annually on self-employment taxes alone.
2026 Tax Brackets & Limits Applied
| Tax Component | LLC Default | S-Corp Election |
|---|---|---|
| Self-Employment / Payroll Tax | 15.3% on 92.35% of net profit | 15.3% on W-2 salary only |
| Social Security Wage Base (2026) | $176,100 | $176,100 (salary capped) |
| Medicare Tax | 1.45% + 0.9% over $200K/$250K | Same on salary only |
| Federal Income Tax | 10%–37% on net profit minus standard deduction | Same on total profit (salary + distributions) |
When Does S-Corp Election Make Sense?
Tax professionals generally recommend considering S-Corp election when your net business profit exceeds $70,000–$80,000 annually. Below that threshold, the administrative costs (payroll service, separate business tax return, bookkeeping) often outweigh the SECA tax savings. Above $100,000, the savings typically justify the extra compliance.
- <$60K profit: Default LLC is usually better
- $70K–$100K: Gray area. Depends on payroll costs & comfort with compliance
- >$100K: S-Corp election almost always saves significant money
Step-by-Step S-Corp Filing Requirements 2026
Electing S-Corp status isn’t automatic. You must follow strict IRS deadlines and compliance rules:
- File Form 2553: Submit “Election by a Small Business Corporation” to the IRS. Must be filed no later than 2 months and 15 days after the beginning of the tax year, or at any time during the prior tax year.
- Pay a Reasonable Salary: You cannot pay yourself $0 salary and take everything as distributions. The IRS will reclassify distributions as wages if the salary is “unreasonably low” for your industry, hours, and experience.
- Run Payroll: You must withhold federal/state income tax, pay the employer FICA match, and file quarterly payroll returns (Form 941).
- File Form 1120-S: S-Corps require a separate business tax return, unlike single-member LLCs (which file on Schedule C).
- Issue K-1 & W-2: You’ll receive a Schedule K-1 for your share of distributions and a W-2 for your salary.
Common Mistakes & IRS Audit Triggers
- Zero or token salary: Taking a $10,000 salary on $200,000 profit guarantees IRS scrutiny.
- Late Form 2553: Missing the deadline means you’ll be stuck with LLC default taxation for another year.
- Mixing personal & business funds: S-Corps must maintain corporate formalities. Piercing the corporate veil risks liability and tax penalties.
- Ignoring state requirements: California charges an 8.84% franchise tax on S-Corps. New York imposes a city-level tax. Always check state-specific S-Corp rules.

Frequently Asked Questions: LLC vs S-Corp 2026
At what profit should I switch from LLC to S-Corp?
Most tax advisors recommend switching when your net business profit consistently exceeds $70,000–$80,000 annually. Below this, payroll and compliance costs often negate SECA tax savings. Above $100,000, the 15.3% self-employment tax reduction on distributions usually saves thousands.
What is a “reasonable salary” for an S-Corp in 2026?
The IRS doesn’t provide a fixed formula. Factors include industry standards, your role, hours worked, business location, and experience. A common baseline is 40–60% of net profit. Setting it below 30% significantly increases audit risk. Use industry salary surveys or IRS Publication 15 for guidance.
Does the S-Corp election affect my federal income tax?
No. Both LLC default and S-Corp are pass-through entities. Your total taxable income remains the same. The S-Corp election only reduces self-employment (SECA) tax by shifting a portion of profit to distributions, which are not subject to FICA.
Can I switch back from S-Corp to LLC?
Yes, you can terminate your S-Corp election, but the IRS requires you to wait 5 years before re-electing S-Corp status. Always consult a CPA before making this decision, as it triggers final tax filings and potential liquidation consequences.
Do multi-member LLCs benefit from S-Corp election?
Yes. Multi-member LLCs default to partnership taxation. Electing S-Corp status can still reduce self-employment taxes for active members, but requires allocating reasonable salaries and distributions proportionally to ownership percentages. Complex partnerships should consult a tax attorney.
