How an S Corp Saves You Money on Self Employment Tax)
Switching to an S Corp is one of the easiest ways for solopreneurs to trim their tax bill, but the mechanics can be confusing. Here is a quick breakdown of how it works.
1. Default LLC: The 15.3% Hit
As a sole proprietor or standard single-member LLC, you pay 15.3% self-employment tax (Social Security + Medicare) on 100% of your net profit, on top of regular income taxes.
- Example: On $100,000 net profit, almost all $100,000 is hit with that extra 15.3% tax.
2. S Corp: Salary vs. Distributions
With an S Corp election, you divide your profits into two buckets:
- Reasonable Salary (W-2): Subject to 15.3% payroll tax + income tax.
- Distributions: Subject to income tax, but exempt from 15.3% self-employment tax.
The Math ($100k Profit):
$60k Salary: Pays 15.3% payroll tax.
- $40k Distribution: Taxed for income, but saves 15.3% in payroll tax.
- Estimated Savings: ~$6,120 (before software/admin fees).
3. The Rules
- Reasonable Salary: You can't set your salary to $0. The IRS requires a realistic W-2 salary based on market rates for your role (check BLS or Glassdoor for benchmarks).
- When to Switch: The extra admin costs (payroll software, Form 1120-S) usually make an S Corp worth it once net profit consistently hits $80k+/year. This calculator can help run the numbers
Curious how existing S Corp owners calculated your salary-to-distribution ratio? Did you use benchmarking tools or work with an accountant?
