Thinking About an S Corp Election? Here's How We Decide It With You
We work out whether an S corporation election pays for itself on your numbers, file Form 2553 inside the window, and set up the salary, payroll and returns that come with it.
To be taxed as an S corporation for all of 2027, a calendar-year business must file Form 2553 by March 15, 2027, or at any time during 2026.
An S corporation election can lower self-employment tax for a profitable owner-operated business, because only the owner's W-2 salary carries payroll tax and the rest of the profit can be distributed. It only pays off when the profit is high enough to cover a reasonable salary plus the added cost of payroll and a separate return. Form 2553 is due within 2 months and 15 days of the start of the tax year the election takes effect, so the decision belongs early in the year.
How we handle it
Free consultation
We talk through what the business does, how you are paid now, who owns it and what you expect it to earn. You leave knowing whether the election is worth modelling or clearly premature.
Run the comparison on your numbers
We compare staying as you are with electing S status, using a reasonable salary for your role, the employer payroll taxes on it, and the cost of payroll processing and an extra return. If the gap is small or negative, we tell you so and you keep your current setup.
Set and document reasonable compensation
We work through the factors the IRS lists, such as your duties, hours, training and what comparable businesses pay, and write down how the salary was reached. That record is what supports the figure if it is ever questioned.
File Form 2553 inside the window
We confirm eligibility, the effective date and the tax year, collect every required shareholder consent and file the election. If the deadline has already passed, we check whether the late-election relief in Rev. Proc. 2013-30 is available.
Hand off to payroll, then file the returns
You choose a payroll provider to run the owner's salary; we do not process payroll, but we tell the provider what to set up and reconcile its filings at year end. Then we prepare the federal Form 1120-S, the SC1120S and the shareholder K-1s.
What to have ready
- Your entity's formation documents and EIN letter
- The last two years of business and personal tax returns
- A current-year profit and loss statement, even a rough one
- What you pay yourself now and how (draws, guaranteed payments)
- Every owner's name, ownership percentage and state of residence
- Any IRS letter about an earlier election (Form 8832 or 2553)
- Your payroll provider's name, if you already have one
- Health insurance premiums the business pays for owners
Please don’t send tax documents or Social Security numbers through the website form. Bring them to the consultation. More in documents to bring to your CPA.
When the election tends to make sense, and when it does not
Self-employment tax is 15.3% of net self-employment earnings (12.4% Social Security, up to that year's wage base, and 2.9% Medicare). An S corporation does not remove that tax from your pay; it limits it to the salary. The saving is the tax on the profit above a reasonable salary, minus what the structure costs to run. That is why the answer depends on your profit, your role and your costs rather than on a rule of thumb.
| Usually worth modelling | Usually not yet |
|---|---|
| Steady profit well above what you would pay someone to do your job | Profit roughly equal to a fair salary for your role |
| The business has been profitable for at least a year and expects to stay that way | First-year business, losses, or very uneven income |
| You are willing to run payroll every pay period, all year | You do not want to run payroll or file quarterly payroll returns |
| All owners are US citizens or residents and share profits by ownership percentage | A partner, corporation or nonresident alien owns part, or profits are split unevenly by agreement |
| Most profit comes from the business, not from rental property | The income is mainly from rental property, which is usually structured differently |
Timing: the 2 months and 15 days window
Form 2553 can be filed at any time during the year before the election is to take effect, or no more than 2 months and 15 days after that tax year begins. For an existing calendar-year business, that means March 15 of the year you want S treatment. A brand-new company has no prior year, so its window runs from the date it first had owners, assets or business activity, and an election filed before that date is not valid.
An LLC does not need a separate Form 8832 to be treated as a corporation when it makes the S election; filing Form 2553 covers both. The election must be signed by an officer, and every shareholder must consent. The IRS says a corporation should generally hear back within 60 days.
If you missed the deadline
A late election generally takes effect the following year. Rev. Proc. 2013-30 offers relief if the business was otherwise eligible, had reasonable cause for filing late, and it and its owners reported income consistently with S status, generally within 3 years and 75 days of the intended effective date. Outside those conditions, the IRS says the only route is a private letter ruling.
What changes after you elect
- The owner who works in the business goes on payroll and is paid a reasonable salary before taking distributions. The IRS can reclassify distributions as wages if the salary is too low.
- Payroll returns and deposits start: federal Forms 941 and 940, South Carolina withholding, and a state unemployment account. Your payroll provider runs these.
- The business files Form 1120-S by the 15th day of the third month after year end, March 15 for a calendar-year company, and issues each owner a Schedule K-1. Form 7004 extends the time to file.
- Health insurance the company pays for an owner of more than 2% goes on that owner's W-2 as wages.
- Owners track their basis, which decides whether distributions and losses are tax-free.
- Owners still make personal estimated payments on their share of the profit.
The South Carolina side
South Carolina follows the federal election: a company with a valid IRS S election files the SC1120S, due the 15th day of the third month after year end, whether or not it had income. It also pays an annual license fee with the return. If any shareholder lives outside South Carolina, the company generally withholds 5% of that shareholder's South Carolina taxable income unless an exception applies, such as the shareholder signing an I-309 affidavit. The state also offers a separate rate election for active trade or business income; how it works with the new 2026 rates is still unsettled, and we review it with you each year rather than assume it.

Questions people ask about this
How much profit do I need before an S corp election is worth it?
There is no single number. It depends on what a reasonable salary is for your role, the payroll taxes on that salary, and what payroll and the extra returns cost you. We run the comparison on your figures in the consultation instead of quoting a threshold.
How is reasonable compensation for an S corp owner decided?
On the facts. The IRS lists factors courts consider, including your training and experience, duties, time devoted to the business, what non-owner employees are paid and what comparable businesses pay for similar services. We pick a figure and write down how we reached it.
What happens if I filed Form 2553 late?
A late election generally takes effect the next year. Relief under Rev. Proc. 2013-30 may let it take effect as intended if you had reasonable cause and meet the other conditions, generally within 3 years and 75 days of the intended effective date. We check whether you qualify before anything is filed.
Do I have to run payroll if I elect S corp status?
Yes, if you work in the business. Your salary is paid as W-2 wages with withholding and payroll returns. We do not run payroll, but we help you set it up with a provider and reconcile it. See Hiring your first employee in South Carolina for what payroll involves.
