When is an S-Corp actually worth it?
An S-Corp usually starts to pay off once your profit is well above a reasonable salary for your work, often around $60,000 to $80,000 or more in profit. You save payroll tax on profit above your salary, but you add payroll, a separate return and possible state costs. Run your own numbers first.

Quick facts
- Saves. Payroll tax on profit above your salary
- Costs. Payroll service, Form 1120-S and state fees
- Common range. Often starts paying off around here
Where does the saving come from?
As a sole proprietor or single-member LLC, you pay self-employment tax on all of your profit. As an S-Corp, you pay FICA only on your salary. The remaining profit passes to you without payroll tax.
| Profit | Salary | SE tax as LLC | Payroll tax as S-Corp | Gross saving |
|---|---|---|---|---|
| $60,000 | $40,000 | About $8,477 | $6,120 | About $2,357 |
| $100,000 | $55,000 | About $14,130 | $8,415 | About $5,715 |
| $150,000 | $70,000 | About $21,194 | $10,710 | About $10,484 |
These are simplified examples, using 2026 rates, and they ignore state taxes and QBI.
What does it cost to run one?
Take off the costs before you celebrate.
- Payroll service, with quarterly and year-end filings
- A separate Form 1120-S, usually more than a Schedule C
- State fees or taxes. California charges 1.5% of S-Corp income, for example
- Time spent on bookkeeping and formalities
So $2,000 of gross saving can vanish once you've paid for it. That's why a low-profit S-Corp often loses money.
What can reduce the benefit?
Your salary has to be reasonable for the work you do. If a fair wage for you is $90,000 and your profit's $100,000, there's little left to save. A lower salary also changes your QBI deduction, and it means lower Social Security credits and smaller retirement contributions.
When should you elect?
File Form 2553 within two months and 15 days of the start of the tax year, so by March 15 for a calendar year. Late elections are often possible with relief under the IRS rules. A new company has 75 days from when it starts. Don't rush it in a year when profit is uncertain.
When is it probably not worth it?
- Profit is under about $40,000
- Your income swings a lot from year to year
- Your salary would use up most of the profit
- You're in a state that treats S-Corps harshly
