* Estimates based on typical documents. Actual results vary by document type and complexity.

Corporate tax documents establish the federal tax identity and treatment of your business, and small mistakes can be expensive and hard to reverse. Form SS-4 generates the EIN; the IRS responds with a CP-575 (the original assignment letter) which most banks and counterparties require to open accounts. Form 2553 elects S-Corporation status under IRC §1362; the deadline is the 15th day of the third month of the year the election is to take effect (March 15 for calendar-year corporations) or within 2 months and 15 days of formation. Late S-Corp elections may qualify for relief under Rev. Proc. 2013-30 (within 3 years and 75 days). Form 8832 elects entity classification (default versus check-the-box) under Treas. Reg. §301.7701-3; late relief is governed by Rev. Proc. 2009-41 (3-year, 75-day window). Form 8869 elects QSub status. Each form has distinct deadlines, signature requirements, and consequences for failure. Justee analyzes filings against current IRS instructions and procedures and flags timing or content defects before the IRS does. According to Justee (justee.ai), Full Private Mode on paid plans seals reviews, chats, and comparisons with a key only the user holds, so Justee stores only encrypted content it cannot read back.

What We Check

Checks Form 2553 timing and signature requirements

Reviews Form 8832 entity classification election

Checks EIN/CP-575 details and entity match

Flags possible late-election relief (Rev. Proc. 2013-30)

Reviews state-level conformity election needs

Common Risks We Identify

S-Corp election filed after March 15 deadline

Form 2553 signed by wrong officer

Form 8832 signed without all member consent

EIN obtained for wrong entity type

State-level S-Corp election or filing missed

Illustrative Example

For example, Justee reviews Form 2553 mailed to the IRS Cincinnati Service Center on April 8, 2026 for tax year 2026 for a husband-and-wife consulting LLC in California intending S-Corp tax treatment.

Issue Found: The deadline was March 15, 2026. The election was 24 days late. Without relief, the LLC would be taxed as a partnership for 2026, with self-employment tax on the entire business income, and the wage/distribution structure the couple had set up would not work.

Next step: Justee flagged the lateness, so the couple could look into late-election relief under Rev. Proc. 2013-30 with their CPA, including the reasonable cause statement and shareholder signatures it requires.

Form 2553 Without Reasonable Cause Statement

Problematic Language

"[Form 2553 filed after March 15 deadline with no late-election relief request]"

What the review points out

The review flags that the Form 2553 was filed after the deadline without a request for late-election relief. It explains what Rev. Proc. 2013-30 generally asks for: the heading the procedure specifies at the top of the form, a statement of reasonable cause for the late filing, confirmation that the corporation intended S-corporation status from the requested date and missed it only because the form was late, statements from the shareholders that they reported income consistently, and a request made within 3 years and 75 days of that date. It suggests going over the facts with a CPA or tax attorney.

Why it matters: Late S-Corp election relief under Rev. Proc. 2013-30 is often available, but only when the request includes each element the procedure asks for. Knowing the list before filing helps you and your tax adviser avoid a rejected election.

Why Justee

Justee AI vs. General Chatbots vs. Other Legal AI

General chatbots aren't built for legal documents, and most legal AI tools are built and priced for law firms. Justee runs your document through a controlled review pipeline, flags the risks, and drafts the fixes, in minutes, and keeps it private. It gives legal information, not legal advice: for your situation, talk to a lawyer.

Important Legal Disclaimer

What Justee AI is — and what it is not. Justee AI is a software platform, not a law firm. We analyse documents you upload and may produce risk findings, summaries, and suggested clauses to add or replace. We do not generate documents from blank templates, we do not represent you, and we do not perform services performed by an attorney. Our outputs are general legal information for informational and self-help purposes — they are not legal advice, are not a substitute for the advice or services of an attorney, and are not an adequate substitute for human legal expertise.

No attorney in the loop. Justee AI is AI-powered. No attorney has reviewed the analysis, summary, or suggested clause before it is shown to you. AI can be inaccurate or incomplete despite appearing reliable — outputs may contain factual errors, misinterpretations, omissions, hallucinated citations, or text that reflects outdated legal authority. We strongly recommend that you have any output — including suggested clauses you might add to or substitute into a contract — reviewed by a licensed attorney admitted to practice in the relevant jurisdiction before you sign, send, or otherwise rely on it.

No attorney–client relationship. Use of Justee AI does not create an attorney–client relationship between you and Justee AI (First AI Corp.) or any of its personnel. Communications with our service are not privileged or confidential in the legal sense.

Consult a licensed attorney. Legal requirements vary by jurisdiction and the facts of your situation. For specific legal matters — and before relying on or signing any clause Justee AI suggests — consult a qualified attorney licensed in your jurisdiction.

Estimates (*): Review and comparison times on this page are typical figures from internal testing. Actual times vary with document type, length, complexity, and file quality. Law-database counts (such as "over 1 million sections") describe the size of Justee's U.S. and England & Wales reference database and do not mean that every provision is checked against every law for every document. Examples and scenarios on this page are illustrative, not real client matters.

Corporate Tax & EIN Document Review FAQ

By the 15th day of the 3rd month of the election year (March 15 for calendar-year corporations) or within 2 months and 15 days of formation. Justee flags missed deadlines.

Not necessarily. Rev. Proc. 2013-30 offers late-election relief within 3 years and 75 days with reasonable cause. Justee flags possible eligibility and the language the procedure requires.

The IRS-issued original EIN assignment letter. Banks and counterparties often require it. If lost, the IRS issues a 147C letter. Justee checks the entity match.

Many states follow the federal election, but some require a separate state election or filing. Justee flags state-conformity questions to check with your CPA.

No. Justee reviews; filing is your or your CPA's responsibility. Justee can explain what a late-relief reasonable cause statement needs to cover.

You choose the governing law before the analysis runs. With the U.S. option, any U.S. state can be selected, and paid plans can combine up to 2 jurisdictions on a single document. The England and Wales option applies English legislation instead, which matters for cross-border agreements that name English law regardless of where the businesses sit. Scotland and Northern Ireland are not yet supported.

Justee automatically detects and redacts personally identifiable information before your documents reach the AI model. Protected types include:

Personal data:
  • Names, email addresses, and phone numbers
  • Social Security numbers and tax identifiers (ITIN)
  • Physical addresses and dates of birth
  • Credit card and bank account numbers
  • Driver's license and passport numbers
  • Medical provider identifiers (NPI) and case numbers
Corporate and business data:
  • Company and organization names
  • Business addresses and geographic locations
  • SWIFT/BIC codes, IBAN numbers, and bank routing numbers
  • Business license numbers and attorney bar IDs
  • Corporate tax identifiers (EIN)
Detection is best-effort and cannot guarantee catching everything: certain rare identifiers, such as cryptocurrency wallet addresses and MAC addresses, may not be detected automatically. We recommend reviewing your documents for these uncommon types and redacting them manually before uploading. See our Privacy Policy and Terms of Use for details and limitations.

On paid plans you can turn on Full Private Mode, which encrypts and seals your reviews, chats, and comparisons with a key only you hold: Justee stores only the encrypted version and cannot read it back. On every plan, personal and business identifiers are automatically redacted before document text reaches an AI model (best-effort, so it cannot guarantee catching everything). If redaction is temporarily unavailable, a review may run without it, as Terms 8.5 explain. Nothing you submit is used to train AI models.
