LLC vs S-Corp Tax Savings Calculator 2026 — Self-Employment Arbitrage
Calculate how much federal self-employment tax (15.3% FICA) an LLC owner can save by electing S-Corporation status and splitting profits into W-2 salary vs distributions.
⚙️ Calculation Parameters
📊 Real-Time Analysis
📐 How It Works: Mathematical Formulas & Methodology
- Net Profit: Net business income reported on Schedule C or Form 1065.
- Reasonable Salary: Mandatory W-2 wages paid to shareholder-employee compliant with IRS Rev. Rul. 74-28.
- 15.3% FICA: Combined Social Security (12.4% up to wage cap) and Medicare (2.9% uncapped) self-employment tax.
- Overhead: Annual cost of separate Form 1120-S corporate tax return preparation and automated payroll processing service ($1,500 - $2,500).
📝 Step-by-Step Practical Calculation Example
Follow this real-world example to calculate or verify your numbers manually:
- A consultant generating $160,000 net profit as a single-member LLC pays 15.3% SE tax on 92.35% of profits = $22,607.
- Under an S-Corp election paying a $75,000 reasonable salary, FICA tax is only $75,000 × 15.3% = $11,475.
- The remaining $85,000 distribution pays zero FICA tax, delivering $11,132 in gross tax savings ($9,132 net after $2,000 payroll/CPA costs).
Accurate financial and mathematical planning requires uncompromised computational fidelity. In accordance with federal standards and standard US banking underwriting practices, this tool calculates exact computational models, statistical distributions, and quantitative projections.

Frequently Asked Questions
At what net profit level does an S-Corp election make sense?
As a general rule of thumb, an S-Corporation election (IRS Form 2553) begins making economic sense once your business generates at least $70,000 to $90,000 in annual net profit, which comfortably covers payroll and accounting overhead.
What is the IRS 'Reasonable Compensation' rule?
The IRS mandates that S-Corp shareholder-employees must be paid a fair, market-rate W-2 wage for the services they provide before taking distributions. Paying yourself an artificially low salary (e.g. $10,000 on $200k profit) triggers IRS reclassification penalties.
How do S-Corp distributions avoid self-employment tax?
Profits distributed as dividends to S-Corporation owners are not subject to the 15.3% FICA (Social Security and Medicare) tax, though they remain subject to federal and state income taxes.
What additional costs come with an S-Corporation?
Running an S-Corp requires running a certified payroll service (e.g. Gusto, ADP) to withhold payroll taxes, paying state unemployment insurance, and hiring a CPA to prepare corporate tax return Form 1120-S ($1,500 to $3,000/yr).
⚖️ LLC vs. S-Corporation Tax Arbitrage: Self-Employment Tax & Reasonable Salary
Small business owners operating as single-member LLCs or sole proprietorships pay 15.3% Self-Employment (SECA) tax on 100% of their net business profits. By electing S-Corporation tax status under Internal Revenue Code Subchapter S, owners can bifurcate business earnings into two buckets: W-2 Wages and Shareholder Dividend Distributions.
Only the W-2 salary component is subject to 15.3% FICA/SECA payroll taxes. Dividend distributions pass through to the owner free of self-employment tax, generating substantial annual tax savings once net profits exceed approximately $70,000.

⚡ IRS Reasonable Compensation Compliance Guidelines
- Establish an Objective 'Reasonable Salary': Under IRS Fact Sheet FS-2008-25, setting a token salary (such as $20,000 on $150,000 profits) triggers immediate IRS audit reclassification and heavy back-tax penalties; use Bureau of Labor Statistics (BLS) wage data for your specific industry.
- Factor In S-Corp Operating Overhead: Maintaining S-Corp status requires running monthly payroll through an automated provider (Gusto/ADP), filing Form 1120-S corporate tax returns, and issuing Form K-1, costing $1,500 to $2,500 annually in administrative fees.
- Time the S-Election with Form 2553: Form 2553 must be filed within 75 days of the start of the tax year (March 15 for calendar-year entities), or late-election relief must be requested under Revenue Procedure 2013-30.
