Short answer: At $100,000 of profit with a $50,000 salary, an S-corp saves about $4,838 a year in 2026 after payroll taxes, a payroll service and extra tax prep, before any state S-corp tax. It starts paying off at about $66,000 of profit at that salary. Full comparison: When Should an LLC Become an S-Corp? The $80K Rule, Tested.

Here is the result above, step by step, using the numbers already filled in.
- Self-employment tax as a sole proprietor$100,000 × 92.35% × 15.3% = $14,130
- Payroll taxes on a $50,000 salary (both halves)$50,000 × 15.3% = $7,650
- Federal unemployment tax0.6% × first $7,000 = $42
- Payroll service and extra tax prep$600 + $1,000 = $1,600
- Extra state S-corp tax (no state chosen)$0
- Yearly savings$14,130 − $7,650 − $42 − $1,600 − $0 = $4,838
- Break-even profitabout $66,000 at a $50,000 salary
How this calculator works
As a sole proprietor or single-member LLC you pay 15.3% self-employment tax on 92.35% of all your profit (IRS: Self-employment tax (Social Security and Medicare taxes)). When the LLC elects to be taxed as an S-corp, you pay yourself a salary through payroll, and only the salary carries the 15.3% Social Security and Medicare tax (split between you and the company). The rest of the profit comes out as distributions, which don't.
The savings aren't free. You'll pay for a payroll service and a separate S-corp tax return (Form 1120-S), federal unemployment tax on the first $7,000 of salary, and in some states an S-corp tax: California charges 1.5% of net income with an $800 minimum, and New York City's 8.85% General Corporation Tax applies to S-corps there. The calculator fills in your state's numbers when you choose it.
The salary is the number that decides the answer. The IRS expects it to be reasonable for the work you do, about what you'd pay someone else to do it (IRS: S corporation compensation and medical insurance issues (reasonable salary)). A higher salary means less savings; see S-Corp Reasonable Salary: How Much Should You Pay Yourself?. The break-even line shows the profit where savings start, found by testing profits in $1,000 steps.
Yearly S-corp savings by profit and salary
| Profit | $35,000 salary | $50,000 salary | $70,000 salary |
|---|---|---|---|
| $50,000 | $68 | −$2,227 | −$2,227 |
| $60,000 | $1,481 | −$814 | −$2,344 |
| $75,000 | $3,600 | $1,305 | −$1,755 |
| $100,000 | $7,133 | $4,838 | $1,778 |

| $200,000 | $21,237 | $18,942 | $15,882 |
2026 federal figures, $600 payroll service and $1,000 extra tax prep, no state S-corp tax. A minus sign means the S-corp costs more than it saves.

Using your result
If the savings are a few thousand dollars or more, bring the numbers to a CPA. They'll check the salary, your state's rules, retirement contributions and the business income deduction, which can all move the answer.
Timing matters. To be taxed as an S-corp for a whole calendar year, file Form 2553 within two months and 15 days of the start of the tax year, which is March 15 for most businesses (IRS: About Form 2553, Election by a Small Business Corporation). Steps are in How to Elect S-Corp Status (Form 2553): Deadlines and Steps.
After electing, set up payroll before your first salary payment, and keep salary and distributions separate in your books.
What it doesn't cover
- State unemployment tax on your own salary isn't included.
- The 20% business income deduction works differently with an S-corp and isn't compared.
- Retirement plans (a solo 401(k) or SEP) can change which structure is better.
- Other local business taxes, like those in Philadelphia, San Francisco and Portland, Oregon, aren't included.
- Not tax advice; confirm with a CPA before electing.
