What Is IRS Form 13997?
Form 13997, titled “Validating Your TIN and Reasonable Cause,” is a specialized IRS response form (OMB No. 1545-2144, revised August 2015 and still current as of 2026). It serves two main purposes:
- Validate or correct your Social Security Number (SSN) or other Taxpayer Identification Number (TIN).
- Provide a written statement explaining reasonable cause for any failure to include complete information on your passport or immigration application.
The IRS uses this form as an attachment to Letter 4318 (IRC 6039E Initial – Passport). It is not a standard tax return but a targeted reply to a proposed penalty notice. Failure to respond properly can result in the $500 penalty being assessed.
Key facts from the form itself:
- Estimated completion time: ~65 minutes total (10 min recordkeeping, 30 min learning, 10 min preparing, 15 min copying/sending).
- You must sign under penalties of perjury that the information is true, correct, and complete.
- Do not mail the form to the generic IRS address printed on it—follow the specific instructions in your Letter 4318.
Why Did You Receive IRS Letter 4318 and Form 13997?
Under IRC §6039E, individuals applying for a U.S. passport or lawful permanent resident (immigrant) status must provide:
- Your TIN (SSN or ITIN, if you have one).
- Any foreign country where you reside.
- Other prescribed information (for immigration: whether you must file a U.S. tax return for the prior 3 years).
The Department of State (for passports) or USCIS (for immigration) forwards incomplete applications to the IRS. If the TIN is missing, invalid, or mismatched, the IRS issues Letter 4318 proposing a $500 penalty per application.
Only one $500 penalty applies per application, regardless of multiple issues. The penalty is not subject to deficiency procedures and is assessed on Form 8278 using Penalty Reference Number (PRN) 679.
You typically have 60 days (or 90 days if the letter was addressed outside the U.S.) to respond.
Understanding the IRC §6039E Penalty
IRC §6039E(c) imposes a flat $500 penalty for each failure to provide the required statement/information unless the failure is “due to reasonable cause and not to willful neglect.”
From IRM 20.1.9.21:
- The penalty applies to passport applicants or those seeking permanent resident status.
- Reasonable cause provides full relief (no penalty assessed).
- If accepted → IRS sends Letter 4319 (No Penalty).
- If not accepted → IRS sends Letter 4320 (Penalty) and assesses it.
The penalty appears on your account as an IMF CP 15 notice on MFT 55.
Step-by-Step: How to Complete Form 13997?
The form is simple and divided into clear sections. Follow these steps exactly:
- Part 1 – If you HAVE a TIN (most common):
- a. Enter your correct Social Security Number (SSN).
- b. Enter any other Taxpayer Identification Number (TIN) if applicable (e.g., ITIN).
- c. Provide a written statement of reasonable cause (attach extra pages if needed). See examples below.
- Part 2 – If you do NOT have a TIN:
- Explain in detail why you do not have (and are not required to have) a TIN or SSN. Attach supporting documentation.
- Signature and Attestation:
- Print your name.
- Sign and date (mm/dd/yyyy).
- The perjury declaration is already printed on the form.
Tip: Attach copies (not originals) of supporting documents: Social Security card, SSA award letter, passport application receipt, name-change court order, marriage certificate, ITIN application (Form W-7) confirmation, etc.
What Is Reasonable Cause? Examples That Work
Reasonable cause exists when you exercised ordinary care and prudence but were still unable to comply due to circumstances beyond your control (IRM 20.1.1 cross-reference).
Strong examples (supported by documentation):
- You applied for your first SSN/ITIN after submitting the passport application (include SSA receipt or Form W-7 acknowledgment).
- Recent name change (marriage, divorce, court order) caused mismatch—attach legal documents showing timeline.
- SSA processing delay (provide appointment confirmation and follow-up dates).
- You were unaware of the TIN requirement at the time of application and corrected it immediately upon receiving Letter 4318.
- Medical emergency or natural disaster prevented timely action (with proof).
Weak or insufficient examples (often rejected):
- “I forgot” or “I didn’t know.”
- Reliance on a preparer or third party without showing your own due diligence.
- Willful neglect (intentional disregard).
Best practice for your statement (keep it to 1 page):
- State facts chronologically with exact dates.
- Describe specific actions you took.
- List attached exhibits.
- End with: “I exercised ordinary care and prudence and respectfully request waiver of the proposed penalty under IRC §6039E.”
How to Submit Form 13997?
Critical: Follow the exact “What You Need to Do” instructions and address/fax number in your Letter 4318. Do not use the address on the form itself.
- Mail: Use certified mail with return receipt for proof.
- Fax: Keep the confirmation page.
- Deadline: Strictly observe the date in your letter.
Retain copies of everything you send.
What Happens After Submission?
- IRS reviews your response.
- Accepted reasonable cause/TIN validated → Letter 4319: No penalty assessed.
- Not accepted → Letter 4320: Penalty assessed; you may request abatement later via Form 843 or appeal.
- If assessed, the penalty appears on your tax account and can be collected like other tax debts.
Responding promptly and completely gives the highest chance of full relief.
Common Mistakes to Avoid
- Leaving the reasonable cause section blank.
- Providing an incorrect or mismatched TIN.
- Forgetting to sign/date the form.
- Sending to the wrong address.
- Failing to attach supporting documents.
- Submitting after the deadline without explanation.
