Uses 2026 federal rates: 15.3% payroll tax on wages, with the 12.4% Social Security portion capped at $184,500. It doesn't include income tax, the qualified business income deduction, state taxes or the 0.9% additional Medicare tax, so treat it as a starting point rather than tax advice.

What the number means

As a sole proprietor or single-member LLC, every dollar of profit is hit with self-employment tax, which is 15.3% on most of it. An S corp splits your income in two. You pay yourself a salary, and that salary carries the same payroll taxes. Whatever profit is left can come out as distributions, and distributions don't carry payroll tax.

That gap is the whole savings. It grows as profit rises above a fair salary for your role, and it shrinks or disappears when profit is close to what you'd reasonably pay yourself anyway. The extra cost of running payroll and filing a separate return comes out of the savings, which is why S corps rarely make sense below roughly $40,000 to $50,000 of profit.

What changes when you become an S corp

The tax savings are real, but so is the extra work. Before you file the election, it helps to know what you're signing up for.

You run payroll on yourself

Your salary goes through payroll every pay period, with taxes withheld and payroll returns filed each quarter. Missing deposits brings penalties quickly.

Your salary has to hold up

The IRS looks for owners who pay themselves very little to dodge payroll tax. If your salary is too low, they can reclassify distributions as wages and add back the tax, plus penalties and interest.

A second tax return

The business files its own return, Form 1120-S, due March 15 for calendar-year companies, and you get a K-1 for your personal return. Most owners pay a preparer for this.

Cleaner books, not optional

Salary, distributions and personal expenses all need to stay separate and documented. Mixing them is the fastest way to lose the benefit in an audit.

Smaller Social Security credit

A lower salary means less paid into Social Security, which can mean a smaller benefit later. It can also limit how much you're able to put into some retirement plans.

Timing matters

The election is made on Form 2553. To have it apply to the current year, it's generally due within two months and 15 days of the start of the tax year, so March 15 for most businesses.

Want a second set of eyes before you switch?

Balanced works with S corp owners every month. We help you set a salary you can defend, run payroll, keep salary and distributions clean on the books, and work alongside your CPA at tax time. If the S corp doesn't make sense yet, we'll tell you that too.

Common questions

At what profit does an S corp start to make sense?

For most small businesses, somewhere around $40,000 to $50,000 of profit, depending on what a reasonable salary looks like for your role and what you pay to run payroll and file the extra return. Move the sliders above to find your own break-even.

What counts as a reasonable salary?

Roughly what you'd have to pay someone else to do the work you do. The IRS looks at your role, hours, industry and what similar businesses pay. There's no fixed percentage, and a salary that looks low next to your profit is the most common thing that draws attention.

Can an LLC be taxed as an S corp?

Yes. An LLC can elect S corp tax treatment by filing Form 2553 with the IRS. Nothing about the LLC itself changes, only how it's taxed.

Does this include income tax?

No. The calculator looks only at payroll and self-employment tax, which is where the S corp savings come from. Your income tax can shift too, mostly through the qualified business income deduction, so check the full picture with your tax preparer before you elect.
