At What Income Is an S-Corp Worth It? The 2026 Break-Even

A freelancer emailed me last spring convinced she was leaving money on the table. Her graphic-design LLC had netted $48,000 the year before, and a video told her every LLC should be an S-Corp. She wanted the election filed before the deadline. I ran her numbers and told her to wait a year. At her profit level, the election would have cost her a few hundred dollars, not saved her anything. She is theoretical, a composite of a conversation I have several times every February, but the math is real, and it is the same math that decides this for everyone.

Where the savings actually come from

A sole proprietor or single-member LLC owner pays self-employment tax on business profit. Under IRC §1401, that tax is 15.3%, which is 12.4% for Social Security plus 2.9% for Medicare. It applies to 92.35% of your net earnings, a figure set by IRC §1402(a)(12). The 12.4% Social Security portion stops at the wage base, which the Social Security Administration set at $184,500 for 2026, up from $176,100. The 2.9% Medicare portion never stops.

An S-Corp splits that same profit into two buckets. You pay yourself a salary, which carries the full 15.3% through FICA, and you take the rest as a distribution, which carries no FICA, no self-employment tax, and no net investment income tax. The savings equal the payroll tax you would have paid on the distribution bucket. That is the entire mechanism. Everything else is detail.

So the size of the prize depends on how much of your profit you can move out of the salary bucket. And that is where the break-even hides, because the law does not let you push your salary to zero.

The reasonable-compensation floor

IRC §3121(d) treats a shareholder who works in the business as an employee, and the IRS requires that employee be paid reasonable compensation before any distribution. In Rev. Rul. 74-44, the IRS recharacterized "dividends" paid in place of salary as wages. In its own guidance and in court, the position has held. In Watson v. United States, the Eighth Circuit backed the IRS when it raised an accountant's $24,000 salary to roughly $91,000 and assessed back payroll tax with penalties and interest.

The practical effect is that reasonable compensation is a larger share of a small profit and a smaller share of a large one. If your business nets $45,000, a defensible salary for the work you do might be most of that, leaving almost nothing to distribute. If it nets $150,000, a reasonable salary for the same hours might be $80,000, leaving $70,000 in the distribution bucket. The election gets more powerful as profit climbs, not because the rate changes but because the untaxed slice grows. For how to set that number, see my guide to reasonable compensation.

The fixed cost on the other side of the scale

Against that saving sits a cost that does not care how much you earn. An S-Corp has to run payroll for you, file a separate Form 1120-S on top of your personal 1040, issue you a W-2 and a K-1, and in many states pay a franchise or entity-level fee. In my practice the extra annual cost of all that, over and above what a Schedule C filer spends, usually runs $1,500 to $2,500 for a simple one-owner S-Corp. Some states push it higher. California alone adds an $800 minimum franchise tax plus a 1.5% tax on S-Corp net income, which is why I cover California's S-Corp pitfalls separately.

The break-even is simply the profit level where the payroll-tax saving on your distributions grows past that fixed overhead. Below it, you are paying a CPA to lose money. Above it, the election works.

The 2026 break-even, four profit levels

The table below compares the self-employment tax a sole proprietor pays with the FICA an S-Corp owner pays on a reasonable salary, then subtracts $2,000 of added compliance cost. The salaries shown are illustrative reasonable-comp figures, not a formula, and they get proportionally smaller as profit rises the way real reasonable comp does. All figures use 2026 rates and are rounded. These owners are theoretical.

Read the pattern rather than the exact dollars. At $40,000 the election is a small loss, because the salary has to absorb most of the profit and the tiny remaining saving cannot clear the compliance cost. At $60,000 it roughly washes. By $90,000 it clears the bar comfortably, and by $150,000 the saving is several times the cost. That is why I tell people the honest break-even for a typical one-owner service business sits somewhere between $60,000 and $80,000 of net profit, with real confidence starting around $90,000.

Why the numbers do not add up to exactly 15.3%

The sole-prop column is not 15.3% of profit flat. Self-employment tax applies to 92.35% of net earnings, so the effective rate on profit below the wage base is about 14.13%. FICA on an S-Corp salary, by contrast, applies to the full salary. That small asymmetry is baked into the table. It also means the raw payroll-tax comparison slightly understates the S-Corp cost, which is one more reason not to shave your break-even estimate too close.

What can move your break-even

A few things push the line up or down. If you already have a W-2 job that carries you past the $184,500 Social Security wage base, most of the 12.4% saving is gone before you start, and the break-even rises sharply. I walk through that trap in detail in the wage base article. State-level costs move it too. A state with no entity-level tax leaves the federal math intact, while a franchise-tax state raises the overhead you have to clear. And the 20% QBI deduction under IRC §199A, which the One Big Beautiful Bill Act made permanent starting in 2026, nudges against the election at the margin, because shifting income from distributions to W-2 wages trims the qualified income the deduction is based on. None of these change the core mechanism. They just change where the line falls.

The bottom line

Do not elect an S-Corp because you crossed some birthday for your business. Elect it when the payroll tax you will save on distributions clearly beats the cost of payroll, an 1120-S, and your state's fees, with room to spare. For most single-owner businesses that means waiting until net profit is durably in the $60,000-to-$90,000 range or higher, and being able to defend a reasonable salary at whatever level you pick. If you are close to the line, run your real numbers, including any outside W-2 wages, through the EntityIQ S-Corp calculator before you file anything. When the election does make sense, my guides on the election deadline and filing Form 2553 take it from there.
