S-Corp Election: How to Elect S-Corp Status for Your LLC

S-Corp Election: How to Elect S-Corp Status for Your LLC

If you’re running a profitable LLC, the S-Corp election could cut your self-employment tax bill by $10,000 or more per year. But the decision isn’t automatic, and the election isn’t something you can undo easily.

Every year, we work with LLC owners who heard “just elect S-Corp” from a friend or a blog post, only to discover the timing was wrong, the math didn’t work, or they didn’t realize what changes were required afterward. The S-Corp election is powerful when it’s right. It’s expensive overhead when it’s not.

This guide covers the decision framework: when the election makes sense, when it doesn’t, how the process works, 2026 deadlines, and what happens after you file. If you’ve already decided and need the step-by-step filing instructions, jump to our Form 2553 S-Corp Election Guide.

What is an S-Corp election?

An S-Corp election is a tax classification choice that allows an LLC or corporation to be taxed under Subchapter S of the Internal Revenue Code. Instead of paying self-employment tax on all profits, S-Corp owners pay themselves a reasonable salary (subject to payroll taxes) and take remaining profits as distributions (not subject to self-employment tax). The election is made by filing IRS Form 2553. For 2026, the deadline is March 16 for calendar-year businesses. An LLC making this election stays an LLC legally but is taxed as an S-Corp.

Key Takeaways

• S-Corp election changes taxes, not legal structure. Your LLC stays an LLC; only the IRS tax treatment changes
• The breakeven point is roughly $50,000-$60,000 net profit. Below that, payroll costs and additional filing fees outweigh the self-employment tax savings
• File Form 2553 by March 16, 2026. Calendar-year deadline for 2026; new businesses get 2 months and 15 days from formation
• You must pay yourself a reasonable salary. The IRS will reclassify distributions as wages if your salary is too low
• Late elections are fixable. Rev. Proc. 2013-30 allows retroactive elections up to 3 years and 75 days late
• Not every LLC benefits. Solo owners under $50K profit, businesses needing multiple stock classes, or companies with foreign owners should stay as-is

What Is an S-Corp Election? (And Why LLCs File It)

An S-Corp election is a federal tax classification under IRC Section 1362. It isn’t a business structure. Your LLC remains an LLC in the eyes of your state. Nothing changes about your operating agreement, your liability protection, or your Articles of Organization.

What changes: how the IRS taxes your income.

Without the S-Corp election, a single-member LLC pays self-employment tax (15.3%) on all net profit. The owner and the business are the same person for tax purposes. With the S-Corp election, you split income into two buckets:

• Salary: subject to payroll taxes (the employer and employee each pay 7.65%)
• Distributions: not subject to self-employment or payroll taxes

That split is where the savings come from. Instead of paying 15.3% on everything, you pay it on just your salary portion and take the rest as a tax-advantaged distribution.

For a complete breakdown of S-Corp taxation, including distributions, health insurance, and retirement contributions, see our S-Corporation Tax Guide.

When Does the S-Corp Election Make Sense?

The S-Corp election saves money when your net profit is high enough that the self-employment tax savings exceed the costs of running an S-Corp. Here’s how to think about it:

Below $50,000 net profit: Probably not worth it. Payroll service fees ($50-$150/month), the additional 1120-S tax return ($1,500-$3,500), and potential worker’s compensation costs eat into savings that are already modest. The math rarely works at this level.

$50,000-$80,000 net profit: Run the numbers carefully. You could save $3,000-$6,000 in self-employment tax, but after S-Corp costs, the net benefit might be $1,000-$3,000. Worth doing, but the margin for error is thin. If your income fluctuates year to year, a down year could mean you’re paying for S-Corp infrastructure with no tax benefit.

$80,000+ net profit: Almost always beneficial. At this level, the self-employment tax savings typically exceed $6,000 even after accounting for all additional costs. The higher your profit, the more you save.

The wildcard most people miss: state taxes. California charges a 1.5% franchise tax on S-Corp net income with an $800 minimum. New York City ignores S-Corp status entirely. Your state can shift the math significantly.

S-Corp Election Deadlines for 2026

The rule for existing calendar-year businesses: file Form 2553 by the 15th day of the third month (March 15). In 2026, March 15 falls on a Sunday, so the deadline shifts to March 16, 2026.

New businesses get 2 months and 15 days from their formation date. Miss the window, and you’ll need to either file a late election or wait until the following tax year.

For detailed line-by-line filing instructions, including where to mail or fax the form, see our Form 2553 S-Corp Election Guide.

How to Make the S-Corp Election (Step by Step)

1. Confirm eligibility. Domestic entity, 100 or fewer shareholders, all eligible shareholder types, one class of stock. See our Form 2553 guide for the full checklist.

2. Get an EIN. If your LLC doesn’t have one, apply at IRS.gov. You’ll need this before filing Form 2553.

3. Download Form 2553. Available at IRS.gov. Use the current revision (December 2020 as of this writing).

4. Complete the form. Fill out Part I with your entity information and have all shareholders sign Column K.

5. Mail or fax to the IRS. Eastern states go to Kansas City, MO; western states go to Ogden, UT. Faxing is faster. See our Form 2553 guide for specific addresses and fax numbers.

6. Wait for the determination letter. The IRS sends acceptance (CP261) or denial within 60 days.

7. Set up payroll immediately. Once the election is effective, you must pay yourself a reasonable salary and remit payroll taxes. This isn’t optional. The IRS will reclassify your distributions as wages if you skip this step.

8. File Form 1120-S annually. Your S-Corp files its own tax return each year, with income passing through to your personal return on Schedule K-1.

S-Corp Election Tax Savings: Real Example

Let’s look at a two-owner scenario. A marketing agency LLC with $220,000 in net profit, two equal partners.

Without S-Corp election:

Each owner reports $110,000 on Schedule C and pays self-employment tax at 15.3%.

• SE tax per owner: ~$15,563
• Combined SE tax: ~$31,126

With S-Corp election:

Each owner takes a $70,000 salary and $40,000 in distributions.

• Payroll taxes per owner on $70,000: ~$10,710
• SE tax on $40,000 distribution: $0
• Tax savings per owner: ~$4,853
• Combined annual savings: $9,706

After S-Corp costs:

• Payroll service: ~$1,800/year (two employees)
• 1120-S preparation: ~$2,500/year
• Net savings: approximately $5,406/year

The bonus: each owner’s $40,000 distribution qualifies for the 20% QBI deduction under Section 199A, creating up to $8,000 in additional deductible income per owner. That’s not captured in the SE tax savings above; it’s a separate benefit that compounds the value of the S-Corp election.

The salary amounts in this example aren’t random. They’re based on what the IRS would consider reasonable for the owners’ roles, hours, and industry. Getting this number right is critical. Set it too low and the IRS reclassifies your distributions as wages. Set it too high and you’re overpaying payroll taxes.

Late S-Corp Election: What If You Missed the Deadline?

Yes, late election relief exists. The IRS allows retroactive S-Corp elections under Rev. Proc. 2013-30 if you meet three conditions:

1. Filed within 3 years and 75 days of the intended effective date
2. All shareholders reported income consistently as if the election was in effect
3. Reasonable cause for the delay

But the process involves more than just submitting a late Form 2553. You’ll need a compliant reasonable cause statement, potentially retroactive payroll setup, and coordination with previously filed tax returns. The reasonable cause statement, in particular, needs to meet specific IRS criteria. Generic language won’t cut it.

This is not a DIY project. Read our full guide: Late S-Corp Election: How to Fix a Missed Filing Deadline.

Missed the deadline? We handle late S-Corp elections routinely as part of onboarding new advisory clients. See our tax advisory services.

When to Revoke the S-Corp Election

Revoking the S-Corp election requires shareholders holding more than 50% of the company’s stock to file a written revocation statement with the IRS. There’s no specific form; it’s a letter sent to the same IRS service center where you filed Form 2553.

Timing matters. If you file the revocation by the 16th day of the third month of the tax year (March 16 for calendar-year businesses), it takes effect for the current year. After that date, revocation takes effect the following year.

The 5-year rule: After revoking, you generally can’t re-elect S-Corp status for 5 years without IRS consent.

Common reasons to revoke:

• Bringing on an ineligible shareholder (venture capital firm, foreign investor)
• Needing multiple classes of stock for outside investment
• Moving to a state with unfavorable S-Corp taxation
• Business income dropped below the break-even point and S-Corp costs no longer make sense

Frequently Asked Questions About the S-Corp Election

Can a single-member LLC elect S-Corp status?

Yes. A single-member LLC can file Form 2553 to elect S-Corp taxation. The LLC keeps its single-member legal structure but is taxed as an S-Corp. You’ll need to set up payroll and pay yourself a reasonable salary once the election is effective.

How long does the S-Corp election take to process?

The IRS typically processes Form 2553 within 60 days. You’ll receive an acceptance letter (CP261) or a denial letter explaining the issue. If you haven’t heard back, call the IRS Business & Specialty Tax Line at (800) 829-4933.

Can I elect S-Corp status mid-year?

For existing businesses, Form 2553 must be filed by the 15th day of the 3rd month (March 16 for 2026 calendar-year businesses). Miss that deadline and the election doesn’t take effect until the following year, unless you file a late election under Rev. Proc. 2013-30. New businesses get 2 months and 15 days from formation.

What’s the difference between an S-Corp and an LLC?

LLC is a legal business structure created under state law. S-Corp is a federal tax classification. An LLC can elect S-Corp taxation by filing Form 2553. After the election, the business is still an LLC legally but files federal taxes as an S-Corp (Form 1120-S instead of Schedule C).

Does the S-Corp election affect my state taxes?

It depends on your state. Most states follow the federal S-Corp election. California imposes a 1.5% franchise tax on S-Corp net income (minimum $800/year). New York City doesn’t recognize S-Corp status at all. Texas has no state income tax, so S-Corp status has no state-level disadvantage there. Always check your specific state’s rules before electing.

Can I make a retroactive S-Corp election?

Yes, under Rev. Proc. 2013-30. If fewer than 3 years and 75 days have passed since the intended effective date, you can file Form 2553 late with a reasonable cause statement. All shareholders must have filed taxes consistently as if the S-Corp election was in effect.

Next Steps: Making the Right Election Decision

The S-Corp election is one of the most effective tax strategies for profitable LLCs. But the election is step one, not the finish line.

After filing Form 2553, you’ll need:

1. Reasonable salary determination: the IRS scrutinizes this more than any other S-Corp compliance issue
2. Payroll setup and quarterly deposits: required from the effective date of the election
3. Quarterly estimated tax projections: your tax situation changes with S-Corp status
4. Annual Form 1120-S filing: a separate business return every year
5. QBI deduction optimization: maximizing the 20% deduction on your distribution income

The election saves you money in year one. Ongoing advisory keeps the savings compounding year after year.

Our Tax Strategy Essentials plan ($300/mo) handles the S-Corp election, reasonable salary determination, quarterly projections, and includes preferred rates on your annual 1120-S return. Tax Strategy Plus ($600/mo) adds a formal reasonable compensation study with IRS-defensible documentation.

If you’ve missed the deadline, we file late elections under Rev. Proc. 2013-30 as part of onboarding. No separate engagement needed.
