LLC vs S-Corp: When Does S-Corp Election Make Sense?
An S-Corp is not a separate business entity. It is a tax election you layer onto your existing LLC. By paying yourself a reasonable salary and taking the rest as a distribution, you avoid self-employment tax on the distribution portion. The math works in your favor once annual net profit exceeds approximately $60,000 to $80,000.
Quick answer:Keep your LLC taxed as a disregarded entity until annual net profit consistently exceeds $60,000 to $80,000. At that point, an S-Corp election typically saves $3,000 to $10,000/yr in SE tax, enough to offset the added payroll and accounting cost. Your state tax situation may change this threshold.
The breakeven is real, not hypothetical: the IRS counted 5.3 million active S-corporation returns for tax year 2022, averaging $144,924 in business net income per return, and only about 66% reported a net profit in a given year, a reminder that the election pays off only once profit is established.

Frequently Asked Questions
An S-Corp is not a separate business structure. It is a federal tax election you make with the IRS by filing Form 2553. Your LLC remains an LLC under state law; the change is purely how the IRS taxes you. By default, a single-member LLC is taxed as a disregarded entity: you pay 15.3% self-employment tax on 92.35% of net profit, with the 12.4% Social Security part applying only up to the annual wage base, plus ordinary income tax. With an S-Corp election, your income is split into two buckets: a reasonable salary (subject to SE tax and FICA withholding) and a distribution (exempt from SE tax). At $100,000 in profit with a $50,000 salary, for example, self-employment tax on the whole profit would be about $14,130 (15.3% of 92.35% of $100,000), while Social Security and Medicare taxes on the salary come to $7,650 (15.3% of $50,000), a difference of roughly $6,480 per year before the cost of payroll administration and before any change in income tax.
S-Corp election typically saves money when your LLC's annual net profit consistently exceeds $60,000 to $80,000 per year. Below that threshold, the cost of running payroll ($500 to $2,000/yr through a service like Gusto or ADP), filing Form 1120-S annually, and paying an accountant for the more complex return often exceeds the SE tax savings. The exact breakeven point depends on three variables: your state's treatment of S-Corp income (California taxes an S-Corp at 1.5% of net income, never less than $800), your salary level (IRS expects a 'reasonable' salary, typically 40 to 60% of net profit), and your accountant's additional fees for the S-Corp return.

File IRS Form 2553 (Election by a Small Business Corporation) with the Internal Revenue Service. All members must sign the form. You must file no more than 2 months and 15 days after your LLC's first tax year begins, or by March 15 of the tax year in which you want the election to take effect. If you miss the deadline, late election relief is available in many cases by filing Form 2553 with an explanation of the reason for the late filing. Once accepted, your LLC files Form 1120-S annually instead of Schedule C, and you receive a W-2 as an owner-employee. You must run payroll, make quarterly payroll tax deposits, and issue yourself a W-2 by January 31 each year. Form 1120-S is due March 15.
It depends on your state. Most states recognize the federal S-Corp election and tax the income as pass-through, similar to the default LLC. However, several states impose additional LLC-level or S-Corp-level taxes that affect the math. California taxes an S-Corp at 1.5% of net income, never less than $800 per year. A default California LLC already owes $800 a year, so the election adds California tax only once 1.5% of net income comes to more than $800 (net income above about $53,000), and that reduces the federal SE tax savings for California LLC owners. New York, New Jersey, and Connecticut also impose S-Corp-level taxes or fees. If you are in one of these states, run the full state + federal calculation before electing S-Corp status.
Yes. You can revoke an S-Corp election by filing a statement of revocation with the IRS. The statement must be signed by shareholders holding more than 50% of the total number of shares of stock (or membership interests). The revocation is effective immediately if filed before the first day of the tax year, or at the start of the following tax year if filed after the year begins. Revoking mid-year creates income allocation complications. You will need to divide the year into an S-Corp period and a C-Corp or partnership period for tax purposes. You should consult a CPA before revoking. After revocation, you may not re-elect S-Corp status for five years without IRS consent.
