When does the S-corp election pay off? Your break-even game plan

Who this is for

• A domestic corporation, or an LLC eligible to elect corporate treatment, that meets the S-corp tests in the Form 2553 instructions.
• Best fit: steady profit that comfortably exceeds a reasonable salary for your role.

The 2026 numbers

• Self-employment tax: 15.3% (12.4% Social Security + 2.9% Medicare). The Social Security part applies up to $184,500 in 2026.¹
• Payroll FICA on your salary: 7.65% employee + 7.65% employer, same wage base.

The break-even formula

Think of it as two columns.

Column A, what you keep: roughly the payroll-tax rate applied to the profit you take as distributions instead of salary. Above the Social Security wage base, only the 2.9% Medicare part applies.

Column B, what it costs: payroll processing, the Form 1120-S return, any state S-corp fees or taxes, and state unemployment tax on your salary.

Break-even is the profit level where Column A equals Column B. Above it, the election is working for you.

How to do it right

1. Set a reasonable salary first. The math only holds when your salary matches your work.
2. Do the two columns with this year’s real profit.
3. File Form 2553 on time. File no more than 2 months and 15 days after the start of the tax year you want it to take effect, or any time during the year before. For a calendar-year S corp starting Jan 1, 2027, that’s any time in 2026 or by March 15, 2027.²
4. Missed the window? There’s a path back. Under Rev. Proc. 2013-30, a late election can often be fixed if you file within 3 years and 75 days of the intended effective date, have reasonable cause, and act promptly once you notice. Write "FILED PURSUANT TO REV. PROC. 2013-30" at the top of Form 2553 and explain the reasonable cause.³
5. Get every shareholder’s consent signature on Form 2553, and keep the IRS acceptance letter with your corporate records.
6. Start payroll on the effective date so your salary flows on W-2s.

Run it by your CPA

Ask your CPA to model this year’s profit both ways. A 20-minute side-by-side can show you exactly where your break-even sits.

Every business is a little different, so check with your CPA for your situation. Good CPAs are on your team, and they love an owner who shows up with the homework done.
