Fill IRS Form 2553 online — free, in your browser
IRS Form 2553, Election by a Small Business Corporation, is how an eligible corporation — or an LLC electing to be taxed as a corporation — elects S-corporation status under section 1362. AttachKit opens the official blank PDF and fills it right in your browser: it auto-fills the entity's name, mailing street address, and employer identification number from a saved profile using on-device heuristics, then leaves the election dates, shareholder consents, and signatures for you to complete and review. Your PDF never leaves your device.
Your PDF never leaves your browser — open DevTools → Network and watch: the file is never uploaded.
Who needs it: Small-business owners electing S-corporation tax treatment, and the accountants and CPAs who prepare Form 2553 for their clients. Newly-formed corporations and LLCs choosing S-corp status — generally filed within 2 months and 15 days of the start of the tax year the election is to take effect.

Form 2553 questions, answered
General information, not legal or tax advice
This page is general information about a commonly-used tax form. Tax law is complex and fact-specific — for advice on your return, consult a CPA, enrolled agent, or tax attorney. AttachKit fills the PDF; the IRS holds you responsible for what's on it.
- Does AttachKit file Form 2553 with the IRS?
- No. AttachKit fills the PDF in your browser; you download it and submit it to the IRS yourself — by fax or mail to the service center listed in the current Form 2553 instructions. This isn't tax advice — check the official instructions or a tax professional.
- Why aren't the city, state, and ZIP auto-filled?
- On Form 2553 the city, state or province, country, and ZIP share a single combined line, so AttachKit fills the entity name, street address, and EIN and leaves that combined line for you to complete — splitting it automatically could put the wrong value in the wrong place.
- Can I sign it in AttachKit?
- Yes — fill via /fill/2553, then click 'Sign' in the menu to add your signature on the same PDF, still entirely in your browser.
