Form 2553: The S-Corp Election Mistakes That Could Cost You Your Tax Status

Making the S-Corp election is theoretically straightforward: file Form 2553, get confirmation, done. In practice, Form 2553 has a surprising number of failure points, and many business owners don't discover the problem until they're mid-audit or trying to prepare returns years after the fact. Here's where the election goes wrong.

Missing the Filing Deadline

For a calendar-year entity, the S-Corp election is generally due no more than 2 months and 15 days after the beginning of the tax year you want it effective — which usually means March 15 — or at any point during the prior tax year. Miss that date and the entity may not have S-Corp status for that year unless it qualifies for late election relief under Rev. Proc. 2013-30. That relief is available if the entity intended to be an S-Corp from the beginning, there's reasonable cause for the late filing, and the entity wasn't otherwise required to file as a C-Corp. It is not something to casually rely on. The entity needs to meet the relief requirements, include the required reasonable-cause statement, and properly request the relief.

Missing Shareholder Signatures

Every shareholder must sign Form 2553, and their consent covers the relevant community property interest if applicable. If one shareholder doesn't sign, the election is invalid. This creates problems in multi-owner situations where one owner is uncooperative, unavailable, or unaware they needed to sign. Every person who was a shareholder during any portion of the election period must consent—not just current shareholders.

Ineligible Shareholders

S-Corporations can only have eligible shareholders. Ineligible shareholders include nonresident aliens, most corporations, partnerships, most trusts, and most multi-member LLCs taxed as partnerships. Some trusts can qualify, but the trust rules are technical. If an ineligible shareholder acquires stock, S-Corp status can terminate as of the date of the disqualifying transfer. This creates unexpected C-Corp taxation going back potentially months, with all the double-tax consequences that come with it.

Exceeding 100 Shareholders or Creating a Second Class of Stock

S-Corps are limited to 100 shareholders, though family members can elect to be counted as a single shareholder under attribution rules. More commonly overlooked: the one-class-of-stock rule. If your operating agreement or shareholder agreement creates different economic rights between shareholders—different distribution priorities, for example—you may have inadvertently created a second class of stock, which automatically terminates the election.

Confirming the Election Is Actually in Effect

If you made an S-Corp election and aren't certain it was processed, call the IRS business line and ask them to confirm the entity's filing status. You can also request written confirmation or a copy of the accepted Form 2553 for the permanent file. Don't assume the election went through because you mailed the form. Confirmation matters, and the cost of discovering the election failed—years later—is substantial.
