S Corp Vs Llc Calculator
Compare tax implications of S-Corp vs LLC structures based on your income and expenses. Enter values for instant results with step-by-step formulas.
Formula
Tax Savings = LLC Self-Employment Tax - S-Corp Payroll Tax - S-Corp Compliance Costs
The S-Corp advantage comes from paying payroll taxes only on the owner's reasonable salary rather than all net business income. LLC SE tax applies to all net income at 15.3% (up to the Social Security wage base). S-Corp payroll tax applies only to the salary portion. The difference minus additional S-Corp compliance costs equals the net tax savings.
Worked Examples
Example 1: Solo Consultant Comparison
Problem: A solo consultant earns $150,000 in revenue with $30,000 in expenses (net $120,000). Compare taxes as an LLC vs S-Corp with a $70,000 salary. Single filer, 5% state tax.
Solution: LLC: SE Tax on $120,000 = ~$16,956 | Federal tax on ~$85,400 taxable = ~$14,260 | State = $5,190\nLLC Total Tax: ~$36,406\n\nS-Corp: Payroll tax on $70,000 = ~$10,710 | Federal tax on ~$85,400 = ~$14,260 | State = $5,190 | Compliance = $2,000\nS-Corp Total Tax: ~$32,160
Result: S-Corp saves approximately $4,246 per year in this scenario
Example 2: Lower Income Freelancer
Problem: A freelancer earns $60,000 net income. Compare LLC vs S-Corp with a $40,000 salary. Single filer, 5% state tax.
Solution: LLC: SE Tax on $60,000 = ~$8,478 | Federal tax = ~$3,420 | State = $2,530\nLLC Total Tax: ~$14,428\n\nS-Corp: Payroll tax on $40,000 = ~$6,120 | Federal tax = ~$3,420 | State = $2,530 | Compliance = $2,000\nS-Corp Total Tax: ~$14,070
Result: S-Corp saves only ~$358 — not worth the compliance burden at this income level
Frequently Asked Questions
What is the main tax difference between an S-Corp and an LLC?
The primary tax difference lies in how self-employment taxes are applied. In a single-member LLC (taxed as a sole proprietorship), all net business income is subject to self-employment tax at 15.3 percent (12.4% Social Security plus 2.9% Medicare) on the first $168,600 of earnings, with the 2.9% Medicare tax continuing beyond that threshold. In an S-Corp, only the reasonable salary paid to the owner-employee is subject to payroll taxes. Profits distributed beyond that salary are not subject to self-employment or payroll taxes. This means if your business earns $150,000 and you pay yourself a reasonable salary of $70,000, you save self-employment taxes on the remaining $80,000 distribution. This savings can amount to thousands of dollars annually, though it must be weighed against additional compliance costs.
What is a reasonable salary for an S-Corp owner?
The IRS requires S-Corp owner-employees to receive a reasonable salary before taking distributions. A reasonable salary must reflect what you would pay someone with similar experience and qualifications to perform the same work in your industry and geographic area. Setting your salary too low to avoid payroll taxes is a red flag that can trigger IRS audits and penalties including reclassification of distributions as wages with back taxes and penalties. Factors the IRS considers include training and experience, duties and responsibilities, comparable wages in similar businesses, dividend history, compensation agreements, and the use of a formula to determine compensation. A common guideline is that salary should represent 40 to 60 percent of net business income, though this varies significantly by industry and circumstances. Consulting a tax professional is strongly recommended.
When does it make financial sense to elect S-Corp status?
S-Corp election generally becomes financially advantageous when your net business income consistently exceeds $50,000 to $60,000 per year, though the exact threshold depends on your specific situation. Below this level, the self-employment tax savings may not offset the additional costs of S-Corp compliance, which typically include payroll processing fees of $500 to $2,000 annually, additional tax preparation costs of $1,000 to $3,000, state-level S-Corp taxes or franchise fees in some states, and the administrative burden of running payroll. The sweet spot is typically when net income is between $80,000 and $250,000 where the payroll tax savings significantly outweigh compliance costs. Above certain income levels, the Qualified Business Income deduction and other factors may also influence the decision.
