What Is an S-Corp Election? (Form 2553)
An S-Corp election is a tax choice, not a new business structure. Your LLC stays an LLC in every legal sense; you simply file Form 2553 and ask the IRS to tax it as an S-Corporation. The reason people do it is narrow and specific: it can reduce self-employment tax. The reason it is not universal advice is equally specific: it adds payroll, a separate return, and real accounting cost.
What actually changes
Under default taxation, all of your LLC’s net profit is subject to 15.3% self-employment tax. Under S-Corp taxation, you become an employee of your own company. You pay yourself a reasonable salary through payroll — that salary is subject to Social Security and Medicare taxes — and take the remaining profit as distributions, which are not.
A rough illustration: on $100,000 of profit with a $60,000 reasonable salary, payroll taxes apply to the $60,000 rather than the full $100,000. The $40,000 taken as distributions escapes self-employment tax. Income tax still applies to all of it, because an S-Corp remains a pass-through entity.
Nothing about your legal status changes. You are still an LLC under state law with the same liability protection, the same operating agreement, and the same annual report.
The reasonable salary requirement
The IRS requires S-Corp owner-employees to pay themselves reasonable compensation for the work they perform before taking distributions. This is the guardrail that stops everyone from paying a $1 salary and taking everything else tax-advantaged.
“Reasonable” means what a comparable business would pay someone else to do your job — judged on your role, hours, experience, industry, and location. There is no formula in the statute, and the various rules of thumb you will see online are conventions, not law.
Setting the salary too low is the most common way S-Corp owners get into trouble. The IRS can recharacterize distributions as wages and assess back payroll taxes, penalties, and interest. Document how you arrived at the figure, using comparable market salary data, and revisit it as the business grows.
The costs on the other side of the ledger
You must run formal payroll — withholding, deposits, quarterly Form 941 filings, and year-end W-2s — which usually means paying a payroll service. You file a separate business return, Form 1120-S, and issue yourself a K-1, which typically raises your tax preparation fee by several hundred to a few thousand dollars annually.
Add state-level complications: some states impose additional taxes or fees on S-Corps, and a few do not recognize the federal election at all. The all-in annual overhead commonly runs somewhere in the $1,500–$3,000 range once payroll and accounting are counted.
This is why the common guidance is to wait until net profit is consistently around $40,000–$60,000 or higher. Below that, the savings often do not cover the overhead — and the added complexity is a real cost of its own.
How and when to file Form 2553
To take effect for a given tax year, Form 2553 must generally be filed no later than two months and fifteen days after the beginning of that tax year — March 15 for a calendar-year business. You can also file at any point during the preceding year for the following year.
Missing the window is common and often fixable: the IRS provides late election relief under Revenue Procedure 2013-30 if you have reasonable cause and meet the conditions. Do not rely on it as a plan.

Key takeaways
- An S-Corp election is a tax classification — your LLC remains an LLC legally.
- It splits income into a reasonable salary (payroll-taxed) and distributions (not subject to self-employment tax).
- The IRS requires reasonable compensation; too low a salary invites recharacterization plus penalties.
- It adds payroll, a Form 1120-S return, and roughly $1,500–$3,000 a year in overhead.
- File Form 2553 within two months and fifteen days of the tax year start; late relief exists under Rev. Proc. 2013-30.
