When to elect S corp status: the break-even, with real numbers

The S corp election is the most common tax move for a profitable LLC, and the most commonly made too early. Done at the right time, it can save a few thousand dollars a year in self-employment tax. Done too soon, the payroll, the extra tax return and the paperwork cost more than it saves.

This article works out where that line falls, with numbers at three profit levels, and covers the rules you have to follow once you elect.

What the election actually changes

An S corporation isn't a different kind of company. It's a federal tax status that a corporation or an LLC can elect by filing IRS Form 2553. Your LLC stays an LLC under state law. What changes is how the IRS treats the money you take out.

Without the election, all of a single-member LLC's profit is self-employment income. You pay 15.3% self-employment tax on it: 12.4% for Social Security on earnings up to $184,500 in 2026, and 2.9% for Medicare on everything.

With the election, you become an employee of your own company. You pay yourself a salary through payroll, and that salary carries the same 15.3% in payroll taxes, split between the company and you. Profit left over after the salary can be paid out as a distribution, and distributions carry no self-employment or payroll tax. That difference is the whole saving.

The worked numbers

These examples compare only self-employment and payroll taxes for one owner in 2026, before income tax. They assume a salary that is reasonable for the work and a federal unemployment tax of $42 a year on that salary.

Self-employment tax is charged on 92.35% of profit, which is why the LLC column isn't simply 15.3% of the profit figure.

Now take away the running costs. A payroll service for one person costs about $660 a year on Gusto's Simple plan ($49 a month plus $6 per person). Add $42 of federal unemployment tax and some state unemployment tax, and the saving at $60,000 falls to roughly $1,650. At $100,000 it's about $4,250, and at $150,000 about $8,250.

Then there's the tax return. An S corp files its own return, Form 1120-S, and accountants usually charge more to prepare it than the schedule a default LLC adds to your personal return. Ask for a quote before you elect. At $60,000 of profit, that fee alone can take most of what's left.

What counts as a reasonable salary

The election only works if your salary is reasonable. The IRS requires an S corporation to pay its working shareholders reasonable compensation before it makes any other distributions to them, and it can reclassify distributions as wages if the salary is too low.

There is no formula. The IRS looks at factors including:

• your training and experience,
• your duties and responsibilities,
• the time and effort you put into the business,
• what the company pays non-owner employees, and
• what comparable businesses pay for similar services.

A practical way to think about it is to ask what you would have to pay someone else to do your job. A consultant who does all the client work personally will need a salary close to market rates. An owner whose employees generate most of the revenue can justify a lower one, because more of the profit comes from the business rather than from the owner's labor.

The costs people forget

Beyond payroll and the extra return, the election brings a few less obvious costs.

• State taxes. Some states charge S corporations their own tax. California taxes S corporations at 1.5% of net income, with an $800 minimum. A few cities don't recognize S corp status at all.
• A smaller QBI deduction. The qualified business income deduction is based on business profit, not on the salary you pay yourself. Paying a salary reduces the profit the deduction applies to, which claws back part of the saving.
• Retirement contributions. Contributions to some retirement plans are based on your salary. A lower salary can mean a lower contribution limit.
• Admin. Quarterly payroll filings, a W-2 for yourself each January, and a clear line between salary and distributions in your books.

None of these is a reason to avoid the election. They are reasons to run the numbers with an accountant rather than assume the headline saving.

How to elect S corp status

1. Check you qualify. No more than 100 shareholders. Shareholders must be individuals, certain trusts or estates, and not nonresident aliens. One class of stock. A domestic company.
2. File Form 2553 with the IRS, signed by every shareholder. An LLC that files Form 2553 is treated as having elected to be taxed as a corporation as well, so it generally doesn't need a separate Form 8832.
3. Watch the deadline. File no more than 2 months and 15 days after the start of the tax year you want the election to take effect, or at any time during the year before. For a calendar-year business starting S corp treatment on January 1, that usually means by March 15.
4. Set up payroll before your first salary payment, and register with your state for withholding and unemployment tax.
5. Tell your accountant, who will file Form 1120-S each year and issue each shareholder a Schedule K-1.

If you miss the deadline, all isn't lost. Revenue Procedure 2013-30 provides relief for late elections filed within 3 years and 75 days of the intended effective date, as long as there was reasonable cause and the owners reported their income consistently with S corp status. Mark the form "FILED PURSUANT TO REV. PROC. 2013-30."

What a year as an S corp looks like

Electing is a one-time filing. Running the company as an S corp is a routine you repeat every year, and it helps to know what it involves before you commit.

• Every payday. Payroll runs your salary, withholds income tax and your half of Social Security and Medicare, and pays the company's half. A payroll service files and pays these for you. Most owners run payroll monthly or twice a month.
• Every quarter. The company files Form 941, the quarterly payroll tax return, and your state's withholding and unemployment returns. Again, a payroll service usually handles them.
• Through the year. Distributions have no tax withheld, but they are still taxable income on your personal return. Most owners pay quarterly estimated tax to cover them, or raise the withholding on their salary.
• January. You receive a W-2 for your salary, like any employee, and the company files Form 940 for federal unemployment tax.
• By March 15 for a calendar-year company, the S corp files Form 1120-S and gives each shareholder a Schedule K-1 showing their share of profit. Your personal return, due in April, includes both the W-2 and the K-1.

The books matter more than they did before. Salary and distributions must be recorded separately, and personal expenses paid from the business account become a problem quickly.

When the election is the wrong move

• Profit is low or unpredictable. The saving depends on profit above your salary. In a lean year there may be none, but the costs remain.
• You plan to raise venture capital. S corps can have only one class of stock and can't have corporate or foreign shareholders. Investors will want a C corporation. Our comparison of LLCs, S corps and C corps covers why.
• An owner lives outside the US. Nonresident aliens can't be S corp shareholders, so the election isn't available.
• You may sell soon. An S corp election can complicate an asset sale or a change in ownership. Get advice before electing if a sale is on the horizon.

Undoing it later

You can revoke an S corp election with the consent of shareholders holding more than half the shares. After a revocation or termination, the company generally has to wait five years before electing again, unless the IRS consents. That's another reason to elect when the profit is steady, not on the strength of one good year.

The bottom line

Elect S corp status when three things are true: your profit is steady, it's comfortably above a salary you could defend for your work, and an accountant has priced the extra return and state taxes for you. Below that, the plain LLC is simpler and often just as cheap. If you are still deciding how to structure the business at all, start with our guide to starting an LLC.
