Analytical Proof & Invariants

Machine Precision
Governing Mathematical Formula:
FICA Savings = (Net Business Profit - Reasonable Salary) × 15.3%

Step-by-Step Mathematical Derivation

1
Sole Proprietorship FICA Exposure

In a standard LLC or sole proprietorship, 100% of the $160,000 net profit is subject to the 15.3% self-employment tax ($24,480 total).

2
S-Corp Distribution Exemption

Under an S-Corp, FICA taxes apply ONLY to the $70,000 W-2 reasonable salary. The remaining $90,000 is taken as a shareholder profit distribution, which is 100% exempt from FICA taxes.

3
Net Economic Benefit

Gross Tax Savings = $90,000 × 15.3% = $13,770. Subtracting $2,200 for payroll processing and corporate CPA returns yields $11,570 in clean annual cash tax savings.

Frequently Asked Questions

What is the minimum profit where an S-Corp election makes sense? +
An S-Corp election typically makes financial sense once net profit consistently exceeds $80,000 to $100,000 per year, which generates enough FICA tax savings to easily outweigh the $1,500 to $2,500 in added payroll and accounting compliance costs.
How does the IRS determine 'Reasonable Compensation'? +
The IRS looks at RCReports data, Bureau of Labor Statistics (BLS) wage data for your job title, hours worked, business complexity, and compensation paid to comparable non-owner employees. Paying yourself a $10,000 salary on $200k profit is an immediate audit trigger.
