These results are general information generated by software. They are not legal advice, no attorney has reviewed them, and they may not capture everything in your situation. No attorney-client relationship exists between you and anyone as a result of this diagnostic.

Tax Letter Scan is a self-directed technology platform that provides general educational information. It does not provide legal, tax, accounting, or financial advice, and it does not create an attorney-client or other professional relationship. No professional reviews your scan or any generated materials. You decide how to proceed and should consult a qualified professional for advice about your facts.

What this code means

The IRS says it is holding your tax refund because you have not filed one or more tax returns and it believes you may owe taxes.

Check this on your paper

Identify exactly which year's return the notice says is missing and the due date listed for filing it.

General next-step checklist

  1. 01

    File the missing return by the due date listed on the notice, electronically if the year is eligible or by mail to the address shown.

    Include any supporting documentation the notice requests when you mail the return.

  3. 03

    If you already filed, gather proof of filing and contact the IRS at the number on the notice.

What this result cannot tell you

This explanation cannot determine whether you owe for the missing year or when the IRS will release a held refund.

If you want an attorney to review your situation, Law Office of Alexander Powell, PLLC is a separate law firm owned by our founder, Alexander Powell. It handles tax controversy matters in the District of Columbia and Maryland. It is a different company from Cited Authorities LLC, and choosing to contact it is entirely up to you. Contacting the firm does not make you a client. The firm becomes your attorney only if it accepts your matter after a conflict check and you both sign an engagement agreement. Until then, do not treat anything you send as protected by attorney-client privilege, and do not rely on any deadline running or being handled on your behalf.
