How to fill out Form 2553 for 2026: S corporation election instructions

Form 2553 is the form a corporation or LLC files to be taxed as an S corporation. It is filed once, not every year. For calendar-year businesses that want S-corp status starting January 1, 2027, the deadline is March 15, 2027, and you can file any time before then, including now.

What's new for 2027 elections:

  • The election rules are unchanged: eligibility, the 2 months and 15 days deadline, and late election relief within 3 years and 75 days.

  • The IRS has posted a draft revision of Form 2553. Check that you are using the current version on IRS.gov before filing.

  • The qualified business income deduction for S-corp owners is now permanent, which affects the math on whether electing is worth it.

The form itself is short, but mistakes are expensive. A missing shareholder signature or a wrong effective date can leave your business taxed the old way for a full year.

Can your business elect S-corp status?

Requirement

What it means in practice

Domestic entity

A US corporation or an LLC eligible to be taxed as a corporation

100 shareholders or fewer

Family members can count as one shareholder

Eligible shareholders only

Individuals, estates, and certain trusts. Partnerships, corporations, and nonresident aliens cannot own shares

One class of stock

Every share has the same rights to distributions. Different voting rights are allowed

If an operating agreement gives members different distribution rights, fix it before you elect. Unequal distributions can be treated as a second class of stock, which ends the election.

Worked example: a two-partner consulting LLC switching for 2027

Two founders formed an LLC in Ohio in 2024. It has been taxed as a partnership, and they want S-corp status from January 1, 2027.

Item

Entry

Date incorporated

The LLC's 2024 formation date, from the state filing

Effective date (E)

01/01/2027

Tax year (F)

Calendar year

Shareholders (J to N)

Both founders, 50% each, with acquisition dates, SSNs, and 12/31 year ends

Consents (K)

Both founders sign. Ohio is not a community property state, so spouses do not need to sign

Form 8832

Not needed. Filing Form 2553 automatically classifies the LLC as a corporation

Filing deadline

Any time before March 15, 2027

Electing changes more than the tax return. From January 2027, both founders must be on payroll at a reasonable salary, which means quarterly Form 941 filings, an annual Form 940, and separate salary and distribution accounts in the books. Most of the S-corp work starts after the election is accepted.

Your Form 2553 prep checklist

When

Task

Before filing

Confirm with your CPA that S-corp status saves tax at your current profit level

Before filing

Review the operating agreement for unequal distribution rights

Before filing

Collect signatures from every shareholder, and spouses where required

By March 15

File by fax or certified mail and keep proof of filing

About 60 days later

Watch for the CP261 acceptance notice. If nothing arrives, call the IRS business line

Before the first 2027 payroll

Set up payroll, open salary and distribution accounts, and check whether your state needs its own S election

Common mistakes to avoid

  1. Missing a consent. Every shareholder must sign. In community property states such as California and Texas, spouses may need to sign too. One missing signature can invalidate the election.

  2. Using the formation date as the effective date. An LLC formed in 2024 that wants S-corp status from 2027 should enter 01/01/2027. Entering the formation date asks for retroactive treatment.

  3. Ineligible owners. An LLC or partnership listed as a shareholder disqualifies the election. So does a nonresident alien.

  4. Losing the acceptance notice. Lenders, buyers, and auditors ask for the CP261 for years. Store it with your permanent corporate records.

  5. Forgetting the state. Some states, including New York, require a separate state S election. Without it, the state may keep taxing the business as a C corporation.

Missed the deadline?

Missed the Deadline

If you file after March 15, the election normally takes effect the following year. Revenue Procedure 2013-30 lets you keep your intended effective date if you file within 3 years and 75 days of that date, the only problem was timing, and you have reasonable cause. Write "FILED PURSUANT TO REV. PROC. 2013-30" at the top of the form and attach a reasonable cause statement. There is no IRS fee. Have your CPA prepare the statement, since every shareholder must also confirm they reported income consistently with the election.

Professional practice callout

Law firms and healthcare practices organized as professional corporations or PLLCs can generally elect S-corp status. Two things need extra attention. State licensing rules on who may own the practice still apply alongside the IRS eligibility rules. And because owner-attorneys and owner-physicians often earn high incomes, reasonable compensation gets close IRS attention. Set the salary with your CPA before the first payroll. Confirm the treatment for your practice with your CPA before relying on these notes.

Frequently asked questions

Can I file Form 2553 now for an S-corp start on January 1, 2027?

Yes. You can file any time during 2026 for an election effective at the start of 2027. Filing early gives you time to receive the acceptance notice before the first payroll of the year.

Does an LLC need to file Form 8832 before Form 2553?

No. An eligible LLC that files a timely Form 2553 is automatically treated as having elected to be taxed as a corporation. Form 8832 is only needed in specific situations, such as electing C-corp status without S-corp status.

Do I have to file Form 2553 every year?

No. The election stays in effect until you revoke it or the business stops qualifying. If you revoke it, you generally cannot elect again for five years.
