How to Elect S Corporation Tax Treatment for Your LLC

To elect S corporation tax treatment for your LLC, confirm the business meets the IRS eligibility rules under 26 U.S.C. § 1361, then file Form 2553 with the IRS by the deadline, signed by every member. One form does the whole job: an eligible LLC that timely files Form 2553 is automatically treated as having elected corporate classification as well, so a separate Form 8832 is not required.¹

Confirm Your LLC Qualifies

The IRS will reject the election, or terminate it later, if the LLC fails any of the structural tests in the statute.² Run through this list before filing:

The LLC is organized in the United States or under the laws of a U.S. state.
It has no more than 100 members. Spouses and family members within six generations of a common ancestor count as one shareholder for this cap.
Every member is an individual who is a U.S. citizen or resident alien. Partnerships, corporations, and nonresident aliens cannot hold an interest. Narrow exceptions apply for certain estates, qualifying trusts, and tax-exempt organizations.
All members have identical rights to distributions and liquidation proceeds. Voting rights can differ; economic rights cannot.
The business is not a financial institution using the reserve method for bad debts, an insurance company taxed under subchapter L, or a domestic international sales corporation.

The One-Class-of-Stock Trap

The single-class-of-stock rule catches more LLCs than owners expect. Operating agreements drafted for partnership taxation often include guaranteed payments, preferred returns, or waterfall distributions that give members unequal economic rights. Under S corporation rules, those provisions create a prohibited second class of stock. Review your operating agreement before filing and remove anything that splits economic rights unevenly.

Member loans can cause the same problem. If a loan looks like equity because the interest rate depends on profits, or because the note is convertible into a membership interest, the IRS may treat it as a second class of stock. A safe harbor covers “straight debt”: a written unconditional promise to pay a fixed amount on a set date, with a non-contingent interest rate, non-convertible, and held by an eligible shareholder or a bank. Short-term unwritten advances under $10,000 in total also get a safe harbor if both sides treat them as debt and expect repayment in a reasonable time.

Trusts That Hold Membership Interests

If a member holds their interest through a trust, the trust has to fit one of the categories in the statute. The most common is a Qualified Subchapter S Trust, which must distribute all income to a single U.S. citizen or resident beneficiary and cannot allow principal to go to anyone else during that beneficiary’s lifetime.³ Electing Small Business Trusts are another route with their own rules. Revocable living trusts and certain testamentary trusts can qualify for limited windows. A single ineligible trust holding an interest sinks the entire election.

Complete Form 2553

The election is made on IRS Form 2553, “Election by a Small Business Corporation.”⁴ You do not file Form 8832 first. A timely Form 2553 by an eligible LLC handles both the corporate classification and the S election in one step.¹

Gather this information before you sit down to fill it out:

The LLC’s legal name exactly as it appears on state records, its physical address, and its Employer Identification Number.
The date the LLC was formed and the date its first tax year began.
The desired effective date of the S election.
For each member holding an interest at the time of filing: name, address, Social Security number or ITIN, ownership percentage, and the date the interest was acquired.

Every current member must sign the form and consent to the election. A missing signature is one of the most common reasons the IRS rejects a filing, so collect every consent before you send anything.

File It on Time

Form 2553 must be filed no later than two months and 15 days after the beginning of the tax year the election is to cover, or at any point during the preceding tax year.⁵ For a calendar-year LLC, that means March 15 to have the election apply to the current year. File after that and the election rolls to the following January 1.

For a new LLC, the tax year starts on the earliest of three dates: when it first had shareholders, when it acquired assets, or when it began doing business. The two-month-and-15-day window runs from that date. Filing early, even before there is any revenue, removes the risk of missing the cutoff.

Where to Send Form 2553

The IRS does not accept Form 2553 online. It has to be mailed or faxed, and the destination depends on where the LLC’s principal office sits.⁵ Businesses in the eastern states (Connecticut through Wisconsin, plus the mid-Atlantic and Southeast) send to the IRS center in Kansas City, Missouri, or fax to 855-887-7734. Businesses in the western and southern states (Alabama, Alaska, everything west of the Mississippi, plus Florida) send to Ogden, Utah, or fax to 855-214-7520.⁶

Use certified mail or keep the fax confirmation. That paper trail is your proof of timely filing if the IRS later questions the date. Keep the original with your permanent records. There is no filing fee for a standard S election. A user fee applies only when the LLC is asking for a fiscal tax year based on a business purpose.⁷

After You File

When the IRS approves the election, it sends a CP261 notice confirming acceptance.⁸ Keep it with your permanent records; banks, lenders, and state agencies sometimes ask to see it. If something on the form is unclear or incomplete, the IRS usually sends a letter asking for clarification rather than rejecting outright. Respond quickly so the election is not dismissed. Processing takes time, so if several months pass without a response, call the IRS Business and Specialty Tax Line to check status.

If You Missed the Deadline

A late filing is not automatically fatal. Revenue Procedure 2013-30 lets an LLC file a late Form 2553 without paying for a private letter ruling, provided every requirement is met.⁹ Those requirements are:

The LLC intended to be an S corporation as of the desired effective date.
The only defect was the late filing.
The LLC and every member reported income consistent with S corporation status for the year the election should have started and every year since.
The LLC has reasonable cause for the delay and acted diligently to correct it.
Generally, the request is made within three years and 75 days of the intended effective date.¹⁰

To use the relief, file a completed Form 2553 with all shareholder consents and write “FILED PURSUANT TO REV. PROC. 2013-30” across the top.¹⁰ The three-year-and-75-day cap can be waived if the LLC and its members have consistently filed as an S corporation, at least six months have passed since the first Form 1120-S was filed, and neither the LLC nor any member has been contacted by the IRS about the classification issue.

If the relief procedure is not available, the only remaining option is a private letter ruling request, which involves a formal application and a user fee that can run into the thousands.

Check Your State’s Rules

The S election is federal. Most states honor it automatically once the IRS approves. Some do not. The District of Columbia, Louisiana, New Hampshire, Tennessee, and Texas impose their own entity-level taxes regardless of the federal election. New York City does not follow the federal S election. New Jersey and New York require a separate state-level S election filing on top of Form 2553. Skip that step in a state that requires it and the business can end up taxed as a C corporation at the state level even though the federal election is in place. Confirm what your state expects before you assume Form 2553 finishes the job.

What Changes After the Election Takes Effect

The election adds obligations a standard LLC does not have. These matter from day one of the effective date, not from whenever the CP261 notice arrives.

Reasonable Compensation

Any member who works for the business must be paid a “reasonable” salary on a W-2. The Internal Revenue Code sets no dollar figure or formula. The IRS looks at training and experience, duties, time committed, what comparable businesses pay for similar work, and the company’s financial condition.¹¹ Paying an owner-operator a token salary while pushing most of the profit out as distributions is what draws audits. If the IRS finds the salary unreasonably low, it can reclassify distributions as wages and assess back employment taxes, interest, and penalties. Research comparable pay in your industry and set the salary in that range.

Payroll and Employment Tax Filings

The LLC must run payroll for every owner-employee, withhold federal income tax and the employee share of FICA, and pay the employer share of FICA plus federal unemployment tax. Quarterly Form 941 returns are due, and W-2s go out to employees by January 31 each year. Most owners use a payroll service to handle deposits and withholding.

Annual Form 1120-S and Schedule K-1

The LLC files Form 1120-S by the 15th day of the third month after the tax year ends, which is March 15 for calendar-year businesses.¹² Form 7004 buys an automatic six-month extension. Each member gets a Schedule K-1 by the same date, reporting their share of income, deductions, and credits for use on their personal return.¹³

Ending or Losing the Election

An S election stays in place until it is voluntarily revoked or involuntarily terminated. Revocation needs the consent of members holding more than half of the LLC’s membership interests.¹⁴ A revocation filed on or before March 15 of a calendar tax year takes effect January 1 of that year. Filed after March 15, it takes effect the following January 1 unless the revocation names a later date.

Involuntary termination happens the moment the LLC fails an eligibility test: admitting a nonresident alien, exceeding 100 shareholders, or amending the operating agreement in a way that creates a second class of stock. Termination is effective on the date of the disqualifying event, which can leave the LLC taxed as a C corporation partway through a year.

Once the election ends by revocation or termination, the LLC and any successor entity cannot re-elect S status for five tax years unless the IRS grants special permission.¹⁴ That five-year lockout is a strong reason to keep an eye on the eligibility requirements year after year, not only when the election is first made.
