If you run an LLC in the United States, you have probably heard that electing S corp status can save you thousands in taxes. It is one of the most repeated tips in small business circles, and it is true — but only for some businesses. The whole LLC vs S corp question is not about which structure is “better”. It is about how the IRS taxes your profit, and whether that profit is high enough for the election to pay off. This guide explains both setups in plain English and runs the numbers on an $80,000 profit.

The short answer
If your LLC consistently nets around $40,000 to $60,000 a year or more, the S corp election usually saves you money, because you stop paying the 15.3% self-employment tax on the part of your profit taken as distributions. Below that level, extra payroll and filing costs tend to eat the savings. In the LLC vs S corp decision, the maths matters more than the label. If you have not formed your business yet, our LLC vs sole proprietorship comparison is a good place to start.
How your LLC is taxed by default
By default, the IRS does not tax your LLC as its own thing. A one-owner LLC is a “disregarded entity”: you report the profit on Schedule C of your personal tax return. A multi-owner LLC is taxed as a partnership and files Form 1065; each owner then reports their share. (See single vs multi-member LLC for how that choice plays out.) Either way, the profit passes through to you, and you pay two taxes on it: ordinary income tax, plus self-employment tax of 15.3%.
That 15.3% is the figure people underestimate. It covers Social Security — 12.4% on earnings up to the $184,500 wage base in 2026 — and Medicare, 2.9% on everything with no cap. The IRS applies it to 92.35% of net earnings rather than the full amount, but on an $80,000 profit that is still roughly $11,300 in self-employment tax, before income tax. For the full picture, see our guide to LLC taxes.
What the S corp election changes
This is the part that confuses people: electing S corp status does not turn your LLC into a corporation. Your LLC stays an LLC under state law. The S corporation election, made on IRS Form 2553, only changes how the IRS taxes the business: instead of Schedule C, the company files Form 1120-S, and profit still passes through to your personal return. Your federal income tax bill does not change at all.
What changes is the employment tax. As an S corp owner who works in the business, you become an employee of your own company. You must pay yourself a reasonable salary through payroll, and only that salary is hit with the 15.3% payroll taxes. Any profit left over can be taken as shareholder distributions — and distributions are not subject to self-employment tax. That is the entire savings mechanism, and the heart of the LLC vs S corp debate: salary gets the 15.3%, distributions do not.
To qualify, the business must be domestic, have no more than 100 shareholders, offer only one class of stock, and its shareholders must be US individuals or certain trusts and estates — no nonresident aliens, no corporate shareholders. Most small LLCs clear these rules without trouble.
LLC vs S corp: the numbers on $80,000 profit
Let us make it concrete. You net $80,000 from your business in 2026.
Under default LLC taxation, self-employment tax applies to 92.35% of $80,000, which is $73,880. At 15.3%, that is $11,304 in SE tax.
Now the S corp version. You pay yourself a reasonable salary of $40,000 — a plausible figure for many owner-operators. Payroll taxes at 15.3% on $40,000 come to $6,120. The remaining $40,000 comes out as distributions: $0 in employment tax. Gross saving: $5,184.
But the election is not free. A basic payroll service runs about $50 a month ($600 a year), you file Form 941 every quarter, and you issue yourself a W-2 at year end. A business return on Form 1120-S also costs more than a Schedule C — expect roughly $1,500 extra from your accountant. Total added cost: about $2,100 a year.
Net saving: $5,184 minus $2,100, or about $3,084 a year. Not life-changing, but real money. The savings grow with profit: at $120,000 of net profit the same maths typically nets $5,500 to $6,000 a year after costs.
When the S corp election is worth it
- Net profit is steady at roughly $40,000 to $60,000 or more, year after year.
- Your reasonable salary sits clearly below total profit, leaving a healthy chunk for distributions.
- You can run payroll properly, or will pay a service to do it.
- You accept the extra filings: quarterly payroll returns plus Form 1120-S each year.
When it is not worth it
- Profit is thin or unpredictable. If the maths barely works, the paperwork is not worth it.
- Your reasonable salary would eat nearly all your profit — a consultant billing $70,000 with a $65,000 market salary saves almost nothing.
- You dislike admin. Missed payroll deposits bring penalties that wipe out the savings.
- Your state piles extra franchise or minimum taxes onto S corps — check state rules first. Our best-state-to-form-an-LLC guide covers how state costs differ.
The reasonable salary rule
This is where the IRS keeps the game honest. You cannot pay yourself $1 in salary and take $79,999 as distributions. The IRS requires reasonable compensation for the work you do; an artificially low salary lets it reclassify distributions as wages, with back payroll taxes plus interest and penalties.
There is no fixed formula. Reasonable means what you would pay someone else to do your job, given your industry, location, hours, and experience. Document your reasoning — salary surveys, job postings, a note from your accountant — so you can defend the number. For more on taking money out of your company, see how to pay yourself from an LLC.
How to elect S corp status: Form 2553
File IRS Form 2553, “Election by a Small Business Corporation”. For a calendar-year business, the deadline is 2 months and 15 days after the start of the tax year — for 2026 that is March 16, since March 15 falls on a Sunday. A brand-new LLC gets 75 days from formation. That deadline is the single most missed step in the LLC vs S corp process: miss it and the election starts the following year, although the IRS offers late-election relief on reasonable cause.
Once it takes effect, put yourself on payroll from day one, keep business and personal money strictly separate, and file Form 1120-S at year end instead of Schedule C. Before filing, read the IRS on LLC tax classification and the S corporation election.
Frequently asked questions
Does electing S corp status change my LLC legally?
No. Your LLC remains an LLC under state law. The election only changes its federal tax treatment. You still renew the LLC and follow state rules exactly as before.
Will an S corp election lower my income tax?
No. Both setups are pass-through, so your federal income tax works out the same. The election only reduces the 15.3% employment tax on the part of your profit taken as distributions.
Can a single-member LLC elect S corp status?
Yes. Single-member LLCs are among the most common businesses making this election. You simply file Form 2553 by the deadline.
Can I switch back if it does not work out?
You can revoke the election, but treat it as a long-term decision: there are restrictions on making a new election soon after a revocation, so run it past your accountant first.
