The S corp election: when it pays, and when it doesn’t

What the election actually changes

An S corporation isn’t a different kind of business. It’s a tax status. Your LLC or corporation files Form 2553 with the IRS, and from then on it’s taxed as an S corp: profits pass through to your personal return, and the business itself generally doesn’t pay federal income tax.

The real change is how your income is split. As a sole proprietor or single-member LLC, all of your net profit is subject to self-employment tax — 15.3% (12.4% Social Security plus 2.9% Medicare) on 92.35% of net earnings. For 2026, the Social Security piece applies up to a wage base of $184,500; Medicare has no cap.

As an S corp owner who works in the business, you pay yourself a reasonable salary through payroll. That salary carries the same Social Security and Medicare taxes, split between you and the company. Profit above the salary can come out as distributions, which are not subject to those payroll taxes. The gap between total profit and a defensible salary is where the savings live.

A worked example: $180,000 of profit

Take a single consultant-style business owner with $180,000 of net profit in 2026, no other income, and the standard deduction ($16,100 for single filers in 2026). The numbers below are simplified and federal only, but they show the moving parts.

As a sole proprietor, self-employment tax is about $25,433 ($180,000 × 92.35% × 15.3%). As an S corp paying a $90,000 salary, combined payroll taxes are $13,770 ($90,000 × 15.3%). That’s roughly $11,660 less in payroll-type tax.

But the election also shrinks the qualified business income (QBI) deduction, because salary isn’t QBI. In this example the sole proprietor’s QBI deduction is about $30,200 (capped at 20% of taxable income), while the S corp owner’s is about $16,600. Combined with the smaller deduction for the employer share of payroll tax, taxable income ends up about $19,400 higher under the S corp, costing roughly $4,700 at the 24% bracket.

Net federal benefit: about $7,000 before compliance costs. If payroll, the extra return, and bookkeeping add $3,000 a year, the real savings are closer to $4,000 — still worthwhile, but far less than the headline payroll-tax number suggests. Change the salary, the state, or the profit, and the answer moves.

When it tends to pay

The election works best when your profit is well above what you’d reasonably pay someone to do your job, and that profit is steady enough to plan around. Signs it may fit:

• Your business is consistently profitable, not just in a good quarter.
• Your profit meaningfully exceeds a reasonable salary for the work you do.
• You’re willing to run real payroll, with withholding, quarterly payroll tax filings, and W-2s.
• Your income is above the QBI thresholds anyway, or you’re in a specified service field where the QBI deduction is limited or gone at your income, so there’s less deduction to lose.
• You want employer-side retirement contributions tied to W-2 wages, such as in a solo 401(k).

When it doesn’t

There’s no universal break-even income. It depends on your profit, the market salary for your role, your state, and what the added compliance costs you. Anyone who quotes a single figure without looking at those details is guessing. The election often loses when:

• Your profit is modest, so a reasonable salary absorbs most of it.
• Your salary would already exceed the Social Security wage base, so distributions only save the 2.9% Medicare portion (plus the 0.9% Additional Medicare Tax above $200,000 single or $250,000 joint).
• Your state imposes its own entity-level tax, minimum tax, or fee on S corps, or doesn’t recognize the election.
• You give up value elsewhere: a smaller Social Security earnings record, smaller retirement contributions, and a smaller QBI deduction.
• Your income swings widely, making a steady salary hard to set.
• You plan to bring in investors or foreign owners. S corps are limited to 100 shareholders and one class of stock, and nonresident aliens can’t be shareholders.

The ongoing cost and workload

Budget for a separate business return (Form 1120-S, due by the 15th day of the third month after year-end — March 15 for calendar-year companies), payroll software or a provider, state payroll registrations and unemployment accounts, and tighter bookkeeping.

Distributions must follow ownership percentages, which matters if you have partners. Owner health insurance for a more-than-2% shareholder has to be run through payroll and reported on the W-2 to keep the deduction. And you’ll want to track your stock basis, because distributions above basis can be taxable.

None of this is hard, but it is recurring. The savings need to clear these costs every year, not just the first one.

Timing and how to elect

For the election to apply to a full tax year, Form 2553 must be filed no more than two months and 15 days after the beginning of that year (by March 15 for a calendar-year business), or at any time during the prior year. All shareholders must sign the consent. The form is mailed or faxed to the IRS; keep proof of filing and watch for the IRS acceptance letter.

An LLC that timely files Form 2553 is treated as also electing corporate status, so it generally doesn’t need a separate Form 8832.

Missed the deadline? Rev. Proc. 2013-30 offers simplified relief for late elections filed within 3 years and 75 days of the intended effective date, if you had reasonable cause and have reported consistently with S status. It’s useful, but plan so you don’t need it.

Run the numbers before you file

Before you file, model your total cost both ways:

• Self-employment tax without the election versus payroll taxes on a salary you can defend.
• The change in your QBI deduction and taxable income.
• State income, franchise, and payroll taxes.
• Added costs: payroll service, Form 1120-S preparation, state filings.
• Retirement contributions at each salary level.
• How the picture looks in a down year, not just a good one.

What to gather before deciding

A useful election analysis takes an hour or two with the right inputs. Pull together:

• Your last two years of returns and a current-year profit and loss statement
• A realistic projection of next year’s profit, including a conservative case
• Wage data for your role and region, to support a salary range
• Your state’s S corp, franchise, and payroll tax rules
• Quotes for payroll service and business return preparation
• Your retirement plan goals, including whether you want a solo 401(k)

Getting out later

Treat the election as a multi-year decision. You can revoke it with consent of shareholders holding more than half the stock, but if an election is revoked or terminated, you generally can’t re-elect for five years without IRS consent.

Leaving S status can also have side effects, particularly if the company holds appreciated assets or has retained earnings. When we review an election at Tally Tax, we look at the salary, the QBI effect, and the state picture together, because those three usually decide it.
