Form 2553 deadlines, late relief, and what you sign up for

The deadline

Form 2553 must generally be filed no later than two months and fifteen days after the beginning of the tax year the election is to take effect. For a calendar-year business that is 15 March.

You may also file at any time during the preceding tax year, for the following year.

A newly formed entity's two-month-and-fifteen-day window runs from the earliest of: when it first had shareholders, when it first had assets, or when it began doing business — not from the date the state approved the paperwork.

Missing it is usually fixable

Late elections are accepted with some regularity under Rev. Proc. 2013-30. You generally qualify if:

• The entity intended to be classified as an S corporation as of the requested date.
• It failed to qualify solely because the election was not filed in time.
• There is reasonable cause, and you acted with diligence on discovering the problem.
• The request is made within three years and 75 days of the requested effective date.
• Everyone who was a shareholder in the period has reported income consistently with S status.

In practice you write “FILED PURSUANT TO REV. PROC. 2013-30” across the top of Form 2553, attach a reasonable cause statement, and file it — often with the first Form 1120-S.

Eligibility, briefly

• A domestic corporation or an LLC electing corporate treatment.
• No more than 100 shareholders.
• Shareholders must be individuals, certain trusts or estates — not partnerships, corporations, or non-resident aliens.
• Only one class of stock, though differences in voting rights are permitted.
• All shareholders must consent, which is what the signatures on Form 2553 are.

What you are committing to

This is the part that catches people. An S election is not a filing; it is an ongoing payroll and reporting obligation. For a calendar-year corporation:

The 1120-S late-filing penalty is roughly $245 per shareholder per month, up to twelve months. For a single-owner corporation that is about $2,940 a year for a return that produces no tax of its own — which is enough to erase the saving at lower profit levels.

A sensible order of operations

1. Check the arithmetic first. If you are below break-even for your state, none of the rest matters yet. Run it here.
2. Have an entity. An LLC or corporation must exist before it can elect.
3. Get an EIN if you do not have one. It is free and immediate from the IRS.
4. Decide the salary before you file, not after — it determines whether the election was worth making. How to set it defensibly.
5. Set up payroll before the first pay date. This is the obligation people discover late, and it is the one that generates penalties.
6. File Form 2553, keep the acceptance letter (CP261), and diarise the quarterly calendar above.
