What Is IRS Form 15103?

IRS Form 15103 is a two-page document provided by the IRS to taxpayers who appear to have a delinquent Form 1040 individual income tax return. The IRS sends this form when their records show no filed return for a specific tax year, often triggered by third-party income reports like W-2s or 1099s that don’t match any submitted return. It’s essentially a questionnaire that allows you to explain your situation without immediately facing tax assessments or penalties.

The form is not a tax return itself but a tool to communicate with the IRS. According to official guidelines, it’s used to clarify why a return hasn’t been filed, confirm that one has already been submitted, or explain exemptions from filing requirements. This can prevent the IRS from preparing a substitute for return (SFR) on your behalf, which could lead to higher taxes owed due to missed deductions or credits.

Key facts about Form 15103:

  • Revision Date: June 2017 (latest version as of current records).
  • Availability: Downloadable as a PDF from the IRS website.
  • Related Notices: Often accompanies CP59 (initial non-filer notice), CP516 (reminder), CP518 (final notice), or similar alerts.

There’s also a Spanish version, Form 15103 (SP), for non-English speakers.

When Should You Use IRS Form 15103?

You should complete Form 15103 if you’ve received an IRS notice indicating a potential delinquency on your Form 1040 return. Common scenarios include:

  • You’ve Already Filed: If the IRS hasn’t processed your return yet (e.g., filed within the last 8 weeks), use the form to confirm submission and attach a copy.
  • No Filing Required: Explain why you weren’t obligated to file, such as low income, non-resident status, or other exemptions.
  • Filing Late: If you’re submitting a late return, attach it to the form and explain the delay.
  • Deceased Taxpayer: Note the date of death and any alternative filings like Form 1041 for estates.
  • Credit or Refund Situations: If you have overpayments or credits from prior years, indicate how you’d like them applied (e.g., to another tax period or as a refund check).

Important: If you’ve filed recently, you may not need to respond at all—just wait for processing. However, ignoring the notice could lead to enforced collection actions.

Step-by-Step Guide: How to Fill Out IRS Form 15103

Filling out Form 15103 is straightforward, but accuracy is key to avoid further IRS scrutiny. Complete both sides of the form. Here’s a breakdown:
