How the saving works
By default, all of a single-owner LLC's profit is subject to self-employment tax: Social Security on 92.35% of profit up to the $184,500 wage base for 2026, plus Medicare on all of it.
Taxed as an S corp, the LLC pays you a salary, and only the salary carries Social Security and Medicare, half paid by the company and half withheld from you. The rest of the profit comes out as distributions, which carry no payroll tax.
Example: $120,000 of profit. As an LLC, self-employment tax is about $16,955. As an S corp paying a $60,000 salary, payroll tax is $9,180, a saving of $7,775. After $2,500 of extra costs, about $5,275 a year.
Before you elect
- The salary has to be reasonable. The IRS expects what you would pay someone else for your role. A salary set low to avoid payroll tax is the classic S-corp audit target.
- You take on payroll. Quarterly payroll returns, W-2s, and state unemployment and withholding accounts.
- The return changes. The LLC files Form 1120-S and gives you a K-1, usually at a higher preparation cost than Schedule C.
- Some states add cost. California and Illinois tax S corps at the entity level; Texas and Tennessee taxes apply whatever the election. See LLC taxes by state.
- Timing: file Form 2553 within 2 months and 15 days of the start of the tax year it should apply to.

Frequently asked questions
How much does an S corp election save?
It replaces self-employment tax on all of the LLC's profit with payroll tax on a salary only. With $120,000 of profit and a $60,000 salary, the payroll tax saving is about $7,775 a year before the extra costs of running payroll and an S-corp return.
At what profit does an S corp make sense?
There is no single number: it depends on the salary you can justify and what payroll and the extra return cost you. In practice the saving rarely covers the costs until profit is well above a reasonable salary. With $40,000 of profit and a $30,000 salary, this calculator shows a net loss of $1,438.
What is a reasonable salary for an S corp owner?
What the business would pay someone else to do your job. The IRS looks at your training and experience, duties, time spent, what comparable businesses pay, and the company’s dividend history. Paying yourself too little to cut payroll tax is the most common S-corp audit issue.
Does this include income tax?
No. It compares federal employment taxes only. Income tax shifts too: the employer half of payroll tax is deductible, and your salary does not count toward the 20% qualified business income deduction. Ask a tax preparer to model your full return before electing.
How do I elect S corp status for my LLC?
File Form 2553 with the IRS, no more than 2 months and 15 days after the start of the tax year you want it to apply to. Late elections can often be fixed under Rev. Proc. 2013-30 if you had reasonable cause.
Do states treat S corps differently?
Some do. California and Illinois tax S corps at the entity level, the District of Columbia does not recognize the election, and the Texas franchise tax and Tennessee franchise and excise tax apply whatever the federal election. Include any state cost in the extra costs field.
