A tax firm checklist for Form 2553 S corporation election filings

What a tax firm collects before filing Form 2553, who signs the shareholder consent, how to track the IRS acceptance letter, and what to do if it is late. General information, not legal advice.

Owners and admins at small CPA, EA and tax firms

Core takeaway

Confirm entity and tax year, collect every shareholder consent the form requires, file using the current instructions, store the copy, and diary the acceptance notice. Informational, not legal advice.

Form 2553 is the election pack, not the pay decision. IRS pages explain who may elect and when to file. This page is the firm admin checklist: confirm the entity and tax year with the client, collect every shareholder consent signature the form asks for, check the timing rules in the current instructions, point to the current filing address or fax in those instructions rather than copying it, store the filed copy, and diary a follow up for the IRS acceptance notice.

Compensation after the election is accepted is the S corp reasonable salary client review. An EIN that still needs to exist is the Form SS-4 EIN application checklist. The packet that should receive the accepted election is CPA firm client onboarding.

02

Confirm the entity and tax year with the client

A corporation or other entity eligible to be treated as a corporation files Form 2553 to make an election under section 1362(a) to be an S corporation. (About Form 2553)

To qualify, the corporation must be domestic, have only allowable shareholders, have no more than 100 shareholders, have only one class of stock, and not be an ineligible corporation. In order to become an S corporation, the corporation must submit Form 2553 signed by all the shareholders. (S corporations)

Complete and file Form 2553 no more than 2 months and 15 days after the beginning of the tax year the election is to take effect, or at any time during the tax year preceding the tax year it is to take effect. Form 2553 generally must be filed no later than 2 months and 15 days after the date entered for item E. Enter the legal name as stated in the charter or other legal document creating the entity, and enter the EIN. If the corporation does not have an EIN, apply first. (Instructions for Form 2553)

If the EIN does not exist yet, stop and run the Form SS-4 EIN application checklist before anyone dates Form 2553. Do not invent which box to check for the tax year on item F.

04

File it, store the copy, and diary the acceptance notice

Send the original election, not a photocopy, or fax it to the Internal Revenue Service Center listed in the current instructions. If the corporation files by fax, keep the original Form 2553 with the permanent records. Do not type a mailing address or fax number onto this page. Use the Where To File table in the current Instructions for Form 2553. The instructions also say the filing information is subject to change and point to the current Where to File page for Form 2553.

The service center will notify the corporation if its election is accepted and when it will take effect, and will also notify the corporation if the election is not accepted. The corporation should generally receive a determination within 60 days after it has filed Form 2553. If box Q1 in Part II is checked, it will generally take an additional 90 days. If the corporation is not notified of acceptance or nonacceptance within 2 months of the date of filing, or within 5 months if box Q1 is checked, the instructions say to take follow up action. Do not file Form 1120-S for any tax year before the year the election takes effect. (Instructions for Form 2553)

Late election relief exists only as those instructions describe it, including the statement to enter in the top margin when filing pursuant to Rev. Proc. 2013-30. This page does not invent whether a client qualifies or what the IRS will do.

Once the acceptance letter is in the file, owner pay is a separate job. Run the S corp reasonable salary client review. Put the engagement terms around the election in the tax preparation engagement letter tracker if this is a new client.
