Form 2553: electing S corporation tax treatment

Form 2553 is how a corporation — or an LLC that will be treated as one — tells the IRS it wants to be taxed as an S corporation. The election is powerful, because it switches the business from entity-level tax to pass-through treatment, but it is also conditional and time-limited. This guide covers who can make the election, the deadline that governs it, what the form requires, and what the election commits the owners to.

What the election achieves

Making the election on Form 2553 gives the business S corporation status, so that it generally pays no federal income tax at the entity level and instead passes its income through to shareholders on Schedule K-1, taxed on their own returns. The return it then files each year is Form 1120-S. An LLC can reach S status through this form too: under the instructions, an eligible LLC that files a timely Form 2553 is treated as having also elected to be taxed as a corporation, so it does not separately need Form 8832 to get there.

Who is eligible

The election is only available to an entity that meets the S corporation conditions, and it must keep meeting them afterwards:

• It is a domestic corporation (or an eligible entity treated as one).
• It has no more than 100 shareholders.
• It has only eligible shareholders — US individuals, certain trusts and estates, and certain exempt organisations. Nonresident aliens, corporations, and partnerships generally cannot be shareholders.
• It has only one class of stock (differences in voting rights alone are disregarded).

The nonresident-alien restriction in particular ends eligibility the moment such a shareholder is admitted, a point examined in can a nonresident alien own an S corporation.

The deadline

Timing is strict. To take effect for a particular tax year, Form 2553 is generally filed no more than two months and 15 days after the beginning of that tax year, or at any time during the preceding tax year. For a calendar-year business electing from January 1, that lands the deadline around March 15. File within the window and the election is clean; file late and you are into the relief regime rather than the ordinary process — see late S corporation election relief.

Consent, and what it commits you to

Form 2553 requires the consent of every shareholder — the election is not valid without it — along with the corporation's details, the effective date, and the chosen tax year. That unanimity is not a formality: the election binds all owners to pass-through treatment and to the obligations that follow, most notably the requirement that owner-employees receive reasonable compensation through payroll before profit distributions. So the election is best treated as a shared decision made with the tax and payroll consequences in view, rather than a form filed in isolation. Once in effect, the S status continues year to year until it is revoked or the corporation ceases to qualify.
