IRS Form 2553 lets an eligible corporation or other qualifying entity elect to be taxed as an S corporation, subject to shareholder, stock, timing, and consent requirements.
An S election changes federal tax classification; it does not create a corporation under state law. The election can reduce entity-level income taxation in many cases, but it also creates payroll, reasonable-compensation, basis, distribution, and shareholder-reporting responsibilities.

What Is IRS Form 2553?
An eligible domestic entity can elect S corporation status if it has no more than the permitted number of shareholders, has only allowable shareholders, has no nonresident-alien shareholder, and has only one class of stock for federal tax purposes.
All persons who were shareholders during the relevant election period generally must consent. The form identifies the entity, requested effective date, tax year, shareholders, stock ownership, and any late-election relief being requested.
Who Should Use IRS Form 2553?
- A domestic corporation choosing S corporation treatment for a new or existing business.
- An eligible LLC or other entity electing to be classified and taxed as an S corporation.
- A business correcting a missed S election under applicable late-election relief procedures.
- Shareholders and advisers evaluating eligibility, payroll costs, state conformity, and ownership restrictions.
- Not partnerships, foreign corporations, or entities with an ineligible shareholder or prohibited second class of stock.
How to Use or Complete IRS Form 2553
- Confirm the entity exists under state law, has an EIN, and is eligible on the requested effective date.
- Review every shareholder’s citizenship or residency, entity type, stock rights, and acquisition date.
- Choose an allowable tax year and the intended effective date.
- Complete the entity and election information, including any required fiscal-year explanation.
- Obtain timely consent from every required shareholder and spouse or community-property owner when applicable.
- Fax or mail the complete form to the current IRS location, retain proof, and follow up if an acceptance notice is not received.
Form 2553 Deadline
For an election effective at the beginning of a tax year, Form 2553 is generally due no later than two months and 15 days after that tax year begins. It may also be filed at any time during the preceding tax year.
An election filed later generally takes effect for the following tax year unless the entity qualifies for late-election relief. Count the short first tax year carefully when a new entity did not exist on January 1.
Who Can Be an S Corporation Shareholder?
Allowable shareholders generally include individuals who are U.S. citizens or residents, estates, certain trusts, and certain tax-exempt organizations. Partnerships, corporations, and nonresident aliens generally cannot own S corporation stock.
Ownership through a disregarded entity, grantor trust, electing small business trust, or qualified subchapter S trust requires close review. Eligibility can depend on the underlying owner and a separate trust election.
One Class of Stock Rule
An S corporation may have voting and nonvoting shares, but all outstanding shares must confer identical rights to distribution and liquidation proceeds. Governing documents, side agreements, debt instruments, and binding arrangements can create a prohibited second class.
Different payment timing or ordinary commercial agreements do not automatically violate the rule, but unusual shareholder loans, disproportionate distributions, or preferred returns should be reviewed before filing.
Late S Corporation Election Relief
Revenue procedures may permit relief when an entity intended S status, had reasonable cause for missing the deadline, acted consistently with that intent, and corrects the failure within the allowed period. The entity normally explains reasonable cause and includes prescribed representations.
Late-election relief is fact-specific. Filing a Form 1120-S marked as an initial return does not by itself guarantee that the S election is valid.
After the S Election Is Accepted
- File Form 1120-S and furnish Schedule K-1 to shareholders.
- Run payroll and pay reasonable compensation to shareholder-employees before nonwage distributions where required.
- Track shareholder stock and debt basis, accumulated adjustments, distributions, and losses.
- Make federal and state payroll deposits and information filings on time.
- Monitor shareholder and stock eligibility continuously, not only on the election date.
Before You File or Submit
- Use the current official version. Tax forms, addresses, thresholds, and electronic filing procedures can change. Download the form or instructions from the issuing agency immediately before use.
- Match names and taxpayer identification numbers. Confirm that legal names, SSNs, ITINs, EINs, plan numbers, and tax periods agree with the related return and agency records.
- Gather supporting records first. Keep calculations, statements, notices, authorizations, appraisals, receipts, and other documents that support every entry.
- Check the deadline and delivery method. An extension to file does not necessarily extend the time to pay. Private carriers also may require a different street address than USPS.
- Sign where required. An unsigned paper form, missing consent, or incomplete electronic authentication can delay or invalidate a submission.
- Keep a complete copy. Retain the filed form, attachments, confirmation number, proof of mailing, fax confirmation, and payment record.
Common Mistakes to Avoid
- Using the state formation date as the effective date without checking when the entity first had shareholders or assets.
- Missing a shareholder signature, acquisition date, or community-property consent.
- Assuming an LLC is automatically an S corporation after registering with a state.
- Overlooking a trust, foreign owner, corporate owner, or second class of stock.
- Taking distributions while paying no reasonable compensation for services.
- Starting Form 1120-S filings without confirming that the IRS accepted the election.
What Happens After Submission?
The IRS generally sends a written acceptance or rejection notice. Review it for the effective date and keep it with permanent corporate records.
If no notice arrives within the period stated in the instructions, contact the IRS using the current business-assistance channel. Do not repeatedly submit duplicate elections without first checking status.
Processing time is not the same as a legal deadline. Do not submit a duplicate merely because an acknowledgement or response has not arrived. First check the relevant online status tool, confirmation record, or official contact channel. If the agency requests more information, respond by the date and method stated in the notice.
Records to Keep
Keep a copy of the completed submission and all documents used to prepare it. Your file should also contain the tax-year or period involved, the date submitted, the delivery method, any confirmation or tracking number, and notes about later agency correspondence. Retention periods depend on the form and issue, so follow the specific instructions and keep records longer when they may remain material to an audit, refund claim, basis calculation, collection case, election, or amended return.
Frequently Asked Questions
Does Form 2553 form an LLC or corporation?
No. State law forms the legal entity. Form 2553 is a federal tax election.
Does an LLC also need Form 8832?
Often an eligible entity can make both the deemed classification election and S election through a timely Form 2553, but facts and effective dates matter. Review both forms’ instructions.
Can a single-member LLC elect S status?
Yes, if it is an eligible domestic entity and satisfies all S corporation requirements.
Is S corporation treatment always better?
No. Payroll costs, reasonable-compensation rules, loss limitations, state taxes, ownership plans, and administrative burden can outweigh potential savings.
Official Resources
Bottom line: Verify eligibility before the effective date, obtain every required consent, file within the two-month-and-15-day window or valid relief procedure, and wait for written IRS acceptance.
