How to Elect S Corp Status for Your LLC (Form 2553 Walkthrough)

Electing S corp taxation for your LLC comes down to one form, one deadline, and a handful of details that are easy to get wrong. File Form 2553 correctly and on time, and the IRS treats your LLC as an S corporation for tax purposes. Miss a signature or a date, and your election can be delayed a full year.

This walkthrough covers what you need before you file, each part of the form line by line, where to send it, and what to do after the IRS accepts.

What You Need Before You File

Before touching the form, confirm three things. First, your LLC must be eligible: 100 or fewer shareholders, only eligible shareholders (generally US individuals, certain trusts, and estates), and one class of stock. Most small LLCs qualify without thinking twice, but multi-member LLCs with unusual ownership should verify.

Second, get your EIN. You cannot file Form 2553 without an employer identification number, and the IRS will reject an application with “applied for” in the EIN box in many cases. If you do not have one yet, apply on the IRS EIN application page before you start.

Third, decide your effective date. For a calendar-year business filing by March 15, the election can take effect January 1 of the current year. You can also choose a future date. Pick the date deliberately, because payroll obligations start when the election does.

Form 2553 Walkthrough, Part by Part

Part I: Election information

This is the core of the form. Enter your LLC’s legal name, address, and EIN exactly as they appear on your IRS records. A mismatch between the name on the form and the name tied to your EIN is one of the most common reasons elections get kicked back.

Line E asks for the date you want the election to take effect. Line F names your selected tax year, which is the calendar year for most LLCs. Line G confirms whether each shareholder consents, and Line H asks for a contact person. If you are a single-member LLC, you are the only shareholder and you sign once.

Shareholder consent statements

Every shareholder must consent to the election. For each owner, the form needs their name, address, number of shares or percentage of ownership, and signature with the date. In a multi-member LLC, collect every signature before filing. One missing consent invalidates the election for everyone, so chase signatures early rather than discovering the gap after the deadline.

Part II: Late election relief

If you missed the filing deadline, Part II is your safety net. It lets you request relief under Revenue Procedure 2013-30 by explaining the reason for the delay and showing that you acted reasonably. You will also need to write “FILED PURSUANT TO REV. PROC. 2013-30” at the top of the form. Many late elections are granted, but the relief is discretionary, so treat it as a backup plan rather than a strategy.

Part III: Qualified Subchapter S Trust election

Most LLC owners skip this part entirely. It applies only when a trust is a shareholder making a special QSST election. If no trust owns part of your LLC, leave it blank.

Where and How to File

Form 2553 is filed by fax or mail, not electronically. The correct fax number or mailing address depends on your state, and the IRS lists them in the Form 2553 instructions. Faxing is faster and gives you a transmission confirmation, which is worth keeping. If you mail it, use certified mail with return receipt so you can prove the filing date.

Do not staple a check or payment to the form. There is no filing fee for the election itself. And keep a complete copy of everything you send, including the fax confirmation page, in your permanent tax file.

Deadlines and Late Elections

The headline deadline: file within 2 months and 15 days of the beginning of the tax year for which you want the election to apply. For calendar-year filers, that is March 15. File on time and the election covers the whole current year.

Miss the deadline and the election defaults to the following tax year, unless you qualify for late-election relief. To get relief, you generally must show that you intended to elect on time, that the failure was inadvertent, and that you have acted consistently as an S corp since the intended effective date. File the late Form 2553 with the relief statement and the required language at the top, and the IRS grants relief in the great majority of clean cases.

One timing trap to avoid: electing mid-year without planning payroll. Your reasonable salary obligation runs from the effective date of the election. If the election takes effect January 1 but you do not set up payroll until June, you have a compliance gap the IRS can question. Line up your payroll provider before the effective date arrives. For the salary rules themselves, see our guide to the S corp reasonable salary rule.

After the IRS Accepts Your Election

The IRS mails a determination letter, usually within 60 days, confirming your S corp status and effective date. Keep that letter forever. It is the proof your accountant and any future auditor will ask for.

Once accepted, several things change. You must run payroll and pay yourself a reasonable salary. You must file Form 1120-S each year by March 15, with Schedule K-1s for each shareholder. Your estimated tax routine changes too, since withholding from your salary now covers much of what quarterly estimates used to handle.

Also revisit your operating agreement. It was written for a default-taxed LLC, and provisions about distributions and allocations may need updating to reflect S corp realities. This is a good moment for a quick attorney review rather than a DIY patch.

If you are still deciding whether the election is right for you, run the numbers first with our income threshold guide and the LLC vs S corp comparison before you file anything.

Mistakes That Delay or Kill Your Election

The IRS rejects or delays a surprising number of Form 2553 filings for avoidable reasons. The most common is a name and EIN mismatch: the legal name on the form must match IRS records exactly, including punctuation and suffixes like LLC. If you recently formed the LLC, confirm the IRS has your EIN on file before you fax the form.

Missing shareholder signatures are next. Every owner must sign and date the consent, and the IRS checks. A related error is listing the wrong effective date, such as a date before the LLC legally existed. And late filers often forget the required language: without “FILED PURSUANT TO REV. PROC. 2013-30” at the top of the form, plus the relief statement in Part II, a late election is just a late form.

Finally, send the form to the right place. Fax numbers and mailing addresses vary by state, so double-check the instructions for your state before sending.

Frequently Asked Questions

How long does Form 2553 take to process?

The IRS typically mails your acceptance letter within about 60 days of receiving the form. Fax filings tend to move a bit faster than mailed ones. If you have not heard back after 60 days, you can call the IRS business line to check the status.

Can I file Form 2553 online?

No. As of 2026, Form 2553 must be filed by fax or mail to the IRS service center for your state. There is no e-file option for this form, which is why keeping your fax confirmation or certified mail receipt matters.

What happens if I file Form 2553 late?

The election takes effect the following tax year, unless you request and receive late-election relief under Revenue Procedure 2013-30. Relief requires showing the delay was inadvertent and that you have acted as an S corp since the intended date. Most straightforward cases are granted.

Does every LLC member need to sign Form 2553?

Yes. Every shareholder must consent to the election with a signature and date. For a single-member LLC that is just you. For multi-member LLCs, collect all signatures before filing, because one missing consent invalidates the election.

Is there a fee to elect S corp status?

The IRS charges no fee for Form 2553 itself. The real costs come afterward: payroll processing, quarterly filings, and a more expensive annual tax return, typically $2,000 to $4,000 a year combined.
