Self-Employment Tax Savings: LLC vs S Corp vs C Corp in 2026
Quick Answer
Self-employment tax (15.3%) is the single biggest tax burden for small business owners — but your entity choice determines how much you actually pay. LLC owners pay SE tax on all net profit, S Corp owners can avoid SE tax on distributions by paying a reasonable salary, and C Corp owners pay no SE tax at all (but face double taxation on dividends). For most businesses earning $80,000–$300,000, an S Corp saves $5,000–$20,000 annually in SE tax compared to an LLC, making it the sweet spot between simplicity and tax efficiency.
Key Takeaways
- LLC members pay 15.3% self-employment tax on all net earnings — there is no way to reduce this under default sole proprietorship taxation.
- S Corp owners only pay FICA on their W-2 salary — distributions are completely exempt from self-employment tax, creating massive savings at higher income levels.
- C Corp shareholders who are not employees pay zero SE tax — but corporate profits are taxed at 21% at the entity level, plus dividends are taxed again personally.
- The 2026 FICA wage base is $176,100 — only the 2.9% Medicare portion applies above this threshold for both SE tax and FICA.
- Additional Medicare Tax of 0.9% kicks in at $200,000 for high-earning S Corp employees and $250,000 for married filing jointly.
- Break-even income for S Corp SE tax savings is approximately $50,000–$60,000 — below this threshold, payroll costs eat into the savings.
What Is Self-Employment Tax and Why It Matters
Self-employment (SE) tax funds Social Security and Medicare for self-employed individuals. Unlike W-2 employees — who split the 15.3% FICA tax with their employer (7.65% each) — self-employed individuals pay the entire 15.3% themselves.
SE Tax Breakdown (2026)
| Component | Rate | 2026 Wage Base |
|---|---|---|
| Social Security (OASDI) | 12.4% | $176,100 |
| Medicare (HI) | 2.9% | No cap |
| Total SE Tax | 15.3% | — |
| Additional Medicare Tax | +0.9% | Over $200,000 |
The 92.35% adjustment factor applies to SE tax calculations: you only pay SE tax on 92.35% of your net earnings, which accounts for the employer-side deduction.

Self-Employment Tax by Entity Type
1. LLC (Default Sole Proprietorship Taxation)
Under default taxation, a single-member LLC is a disregarded entity. All net profit is subject to SE tax on Schedule SE.
Example: $120,000 Net Profit
| Calculation | Amount |
|---|---|
| Net Profit | $120,000 |
| × 92.35% | $110,820 |
| Social Security (12.4%) | $13,742 |
| Medicare (2.9%) | $3,214 |
| Total SE Tax | $16,956 |
Multi-member LLCs (taxed as partnerships) work similarly — each member pays SE tax on their distributive share of ordinary business income. Limited partners and passive investors may be exempt from SE tax on distributions, but active members are fully subject to it.
Key Point: LLC owners cannot reduce SE tax by splitting income into “salary” and “distributions.” The IRS treats all guaranteed payments and distributive shares of active business income as self-employment income.
2. S Corporation
The S Corp is the gold standard for SE tax savings among pass-through entities. Here’s why: S Corp owner-employees divide income into two categories — W-2 salary (subject to FICA) and distributions (exempt from SE tax).
Example: $120,000 Net Profit, $60,000 Salary
| Component | Amount | Tax Rate | Tax Owed |
|---|---|---|---|
| Salary (W-2) | $60,000 | 15.3% FICA | $9,180 |
| Distributions | $60,000 | 0% SE tax | $0 |
| Total FICA/SE Tax | $9,180 | ||
| Savings vs LLC | $7,776 |
That’s a 46% reduction in employment taxes — achieved simply by choosing the right entity structure and salary split.
The catch: S Corp owners must run payroll (costing $1,200–$3,600/year) and pay themselves a salary that the IRS considers “reasonable.” Too low, and you face audits and penalties. For detailed guidance on this, see our S Corp reasonable compensation IRS enforcement guide.
3. C Corporation
C Corps present an interesting paradox for SE tax: shareholders who are not employees pay zero self-employment tax on dividends. However, C Corp profits are taxed at 21% at the corporate level, and dividends are taxed again at the shareholder level (15–20% qualified dividend rate + 3.8% Net Investment Income Tax).
Example: $120,000 Profit, $60,000 Salary + $60,000 Dividends
| Component | Amount | Employment Tax | Income Tax |
|---|---|---|---|
| Salary (W-2) | $60,000 | $9,180 FICA | Ordinary rates |
| Corporate profit | $60,000 | $0 | 21% = $12,600 |
| Dividends (after corp tax) | ~$47,400 | $0 | 15–23.8% |
| Total Employment Tax | $9,180 |
The C Corp saves the same FICA as the S Corp on the salary side and avoids SE tax on dividends — but the corporate-level tax ($12,600) erases the SE tax savings and then some. C Corps only make SE tax sense when profits are retained in the corporation for growth rather than distributed.

Side-by-Side Comparison: $150,000 Net Profit
Let’s compare all three entity types at a realistic income level, assuming a $70,000 salary for S Corp and C Corp scenarios.
| Metric | LLC (Sole Prop) | S Corp | C Corp |
|---|---|---|---|
| Net Business Income | $150,000 | $150,000 | $150,000 |
| Owner Salary | N/A | $70,000 | $70,000 |
| Distributions/Dividends | $150,000 | $80,000 | $80,000 |
| SE/FICA Tax | $21,175 | $10,710 | $10,710 |
| Corporate Income Tax | $0 | $0 | $16,800 (21%) |
| Payroll Processing Cost | $0 | ~$2,000 | ~$2,000 |
| Effective Employment Tax Rate | 14.1% | 7.1% | 7.1% |
| Net SE Tax Savings vs LLC | — | $10,465 | $10,465 |
| Corporate Tax Cost | — | — | ($16,800) |
| True Net Benefit vs LLC | — | +$8,465 | ($6,335) |
Conclusion: At $150,000 income, the S Corp delivers $8,465 in net savings after payroll costs. The C Corp technically saves the same SE tax but loses it all to corporate-level income tax on retained earnings.

The Break-Even Analysis: When Does an S Corp Save Money?
S Corp SE tax savings only exceed the additional costs (payroll processing, state fees, accounting) above a certain income threshold.
Cost Factors
| Cost Item | Annual Range |
|---|---|
| Payroll Service (Gusto, ADP, etc.) | $1,200–$3,600 |
| State S Corp Franchise Tax (CA, IL, etc.) | $0–$800 |
| Additional Tax Return (1120S vs Schedule C) | $500–$2,000 |
| Workers’ Comp Insurance (if required) | $0–$2,000 |
| Total Additional S Corp Costs | $1,700–$8,400 |
Break-Even Calculation
The annual SE tax savings from an S Corp depend on income and the salary-to-distribution ratio:
Savings Formula:
(Net Profit − Reasonable Salary) × 92.35% × 15.3%
At a 50/50 salary split:
| Net Profit | SE Tax Savings (50/50 split) | Break-Even? |
|---|---|---|
| $40,000 | $2,827 | ❌ Below costs |
| $60,000 | $4,240 | ⚠️ Marginal |
| $80,000 | $5,654 | ✅ Clear savings |
| $100,000 | $7,067 | ✅ Strong savings |
| $150,000 | $10,600 | ✅ Significant |
| $200,000 | $14,133 | ✅ Major |
| $300,000 | $21,200 | ✅ Substantial |
Rule of Thumb: If your net business income consistently exceeds $60,000–$80,000 per year, an S Corp election will likely save you money on self-employment taxes.
High-Income Scenarios: Above the FICA Wage Base
Once W-2 salary exceeds the $176,100 Social Security wage base, the calculus changes:
Scenario: $300,000 Net Profit
LLC:
- SE tax on first $176,100 (× 92.35%): $24,958
- SE tax on remaining $123,900 (× 92.35% × 2.9%): $3,314
- Total: $28,272
S Corp ($150,000 salary):
- FICA on $150,000: $22,950
- Distributions ($150,000): $0
- Total: $22,950
- Savings: $5,322
S Corp ($176,100 salary — maxing out the wage base):
- FICA on $176,100: $26,919
- Distributions ($123,900): $0
- Total: $26,919
- Savings: $1,353
Key Insight: Paradoxically, setting salary at the FICA wage base maximizes Social Security benefits but minimizes SE tax savings. The optimal strategy for pure tax savings is a lower reasonable salary — but this must be balanced against retirement contribution limits (which are based on W-2 compensation) and IRS scrutiny.

Special Situations
Married Couples in Community Property States
In community property states (CA, TX, AZ, NV, etc.), a married couple operating a single-member LLC may be able to split the business income between both spouses for SE tax purposes, potentially reducing the effective rate. However, this strategy has narrow IRS requirements and should be implemented with professional guidance.
Multi-Member LLCs
In a multi-member LLC taxed as a partnership:
- General partners pay SE tax on their full distributive share
- Limited partners may be exempt from SE tax on distributions (but not guaranteed payments)
- The IRS has been aggressive in challenging LP exemptions (see the Castigliola and Soroban cases)
Real Estate Professionals
Rental real estate income is generally exempt from self-employment tax regardless of entity type — unless you’re a real estate dealer. This makes entity choice less critical for pure rental income. For more details, see our real estate investor tax strategy guide.
Single-Member LLCs
Single-member LLCs face the full 15.3% SE tax burden under default taxation. The solution is an S Corp election (Form 2553), but timing matters. See our single-member LLC vs S Corp guide for the full analysis.
Strategies to Maximize SE Tax Savings
1. Elect S Corp Status Early in the Year
File Form 2553 by March 15 (for existing entities) to ensure the S Corp election is effective for the full tax year. Mid-year elections are possible but complicate tax filings.
2. Optimize Your Salary Split
The IRS expects your salary to reflect market rates for your role and location. Resources for benchmarking:
- Bureau of Labor Statistics (BLS) wage data
- Glassdoor and Salary.com
- Industry-specific compensation surveys
A reasonable range is 40–60% of total income as salary, varying by profession.
3. Maximize Retirement Contributions
S Corp owners can contribute to a Solo 401(k) based on W-2 compensation:
- Employee contribution: up to $23,500 (2026)
- Employer contribution: up to 25% of W-2 compensation
- Total limit: $70,000
This further reduces taxable income beyond the SE tax savings.
4. Consider the QBI Deduction Impact
The Qualified Business Income (QBI) deduction (Section 199A) allows eligible pass-through business owners to deduct up to 20% of qualified business income. SE tax savings from an S Corp do not reduce QBI — you get both benefits simultaneously.
5. Track State-Level Implications
Some states impose additional costs on S Corps:
- California: $800 minimum franchise tax + 1.5% on net income
- Illinois: 1.5% replacement tax
- New York: Fixed dollar minimum tax based on NY receipts
- Texas: Franchise tax applies to all entity types (no S Corp disadvantage)
Factor these into your break-even analysis.

FAQ
What is the self-employment tax rate in 2026?
The self-employment tax rate is 15.3%, consisting of 12.4% for Social Security (up to the $176,100 wage base) and 2.9% for Medicare (no cap). An additional 0.9% Medicare surtax applies to earned income exceeding $200,000 ($250,000 for married filing jointly).
How much can an S Corp save in self-employment taxes?
An S Corp typically saves $5,000–$20,000 per year in self-employment taxes compared to an LLC, depending on total income and the salary-to-distribution split. At $150,000 net profit with a 50/50 split, the savings are approximately $10,465 per year.
Does a C Corp pay self-employment tax on dividends?
No. C Corp shareholders who receive dividends do not pay self-employment tax on those dividends. However, dividends are subject to double taxation — the corporation pays 21% income tax on profits, and shareholders pay 15–23.8% on dividends received.
At what income level does an S Corp election make sense for SE tax savings?
Most tax professionals recommend considering an S Corp election when net business income consistently exceeds $60,000–$80,000 per year. Below this threshold, the additional costs of running payroll and filing Form 1120S can exceed the SE tax savings.
Can an LLC owner avoid self-employment tax?
Under default sole proprietorship taxation, an LLC owner cannot avoid SE tax on active business income. The only ways to reduce SE tax are: (1) elect S Corp status and split income between salary and distributions, or (2) generate passive income (rents, royalties, investments) which is generally exempt from SE tax.
How does the Additional Medicare Tax affect S Corp owners?
S Corp owners who pay themselves a W-2 salary exceeding $200,000 ($250,000 married filing jointly) must withhold an additional 0.9% Medicare surtax on amounts above the threshold. This applies only to the salary portion — distributions remain exempt from all employment taxes including the Additional Medicare Tax.
What happens if an S Corp salary is too low?
The IRS can reclassify S Corp distributions as wages under IRC Section 162, resulting in back taxes, penalties (up to 100% of the unpaid FICA), and interest. The IRS has increased S Corp audit scrutiny in 2026, particularly for owner-employees with salary below 30% of total income.
Does the TCJA sunset affect self-employment tax calculations?
The TCJA sunset (expiring provisions after 2025) primarily affects income tax rates and the QBI deduction, not self-employment tax rates or FICA thresholds directly. However, higher income tax rates may change the optimal salary-to-distribution ratio since the value of SE tax deductions changes. See our TCJA sunset analysis for details.
Bottom Line
Your entity choice is the single most impactful decision for self-employment tax optimization:
- LLC (default): Simplest to maintain, but you pay 15.3% on everything. Best for income under $60,000 or side businesses.
- S Corp: The SE tax sweet spot. Saves $5,000–$20,000/year for businesses earning $80,000–$300,000. Requires reasonable salary and payroll processing.
- C Corp: No SE tax on dividends, but corporate-level tax eats the savings. Only optimal if you’re reinvesting profits or planning to go public.
The optimal move for most small business owners: Start as an LLC, then elect S Corp status when net income consistently exceeds $60,000–$80,000. Use the savings to fund retirement accounts and accelerate business growth.
