How does the S-Corp election save you money?
When you operate as a sole proprietor or single-member LLC, you pay self-employment tax at 15.3% on your entire net business income (12.4% Social Security on the first $176,100, plus 2.9% Medicare on everything). On $200,000 in profit, that is approximately $26,000 in SE tax alone — on top of your federal income tax.
An S-Corp election (IRC §1361-1379) splits your income into two categories: a reasonable W-2 salary (subject to FICA) and shareholder distributions (not subject to FICA). Only the salary portion is taxed at 15.3% — the distributions flow to you tax-free from a payroll perspective.
The key requirement is “reasonable compensation” — you must pay yourself what someone else would be paid to do your job. The IRS has successfully challenged owners who set artificially low salaries (see David Watson v. Commissioner, 2012). Our calculator sets the salary at 40-60% of income based on income level, which aligns with IRS guidelines for most service businesses.
To elect S-Corp status, file IRS Form 2553 by March 15 for the current tax year. Late elections are available under Rev. Proc. 2013-30. You will also need to set up payroll through a provider like Gusto or ADP ($40-50/month) and file quarterly Form 941 returns.
Frequently Asked Questions
How much can I save with an S-Corp election?
Savings depend on your net income. At $100,000, you save approximately $7,000-$9,000/year. At $200,000, savings reach $12,000-$16,000/year. At $400,000+, savings exceed $20,000/year. Use the calculator above to see your exact number.
When does an S-Corp election make sense?
Generally when your net business profit exceeds $50,000/year. Below that, the cost of payroll ($1,500-$3,000/year) and additional accounting fees eat into the SE tax savings. The calculator shows your net savings after payroll costs.
What is reasonable compensation for an S-Corp owner?
It is what you would pay someone else to do your job. The IRS examines industry norms, experience, hours worked, and company revenue. Our calculator uses 40-60% of income depending on level, which aligns with IRS guidelines for most service businesses.
How do I elect S-Corp status for my LLC?
File IRS Form 2553 by March 15 for the current tax year, or within 75 days of forming a new entity. Late elections are possible under Rev. Proc. 2013-30 with reasonable cause. You also need to set up payroll and pay yourself a reasonable salary.
Does the S-Corp election affect my QBI deduction?
Yes. Your S-Corp salary reduces QBI (it becomes W-2 income) but increases the W-2 wages limitation that caps the QBI deduction for high earners. The optimal salary balances SE tax savings against QBI deduction — this requires modeling both scenarios.
