IRS letters

Letter 4464C. Return under review letter.

The IRS says it is reviewing whether income, withholding, expenses, and credits are reported accurately on your return and asks you to allow up to 60 days before contacting it.

General information from the Law Office of Alexander Powell, PLLC. It is not legal advice, and it is not a substitute for the notice itself.

On the paper

Note the letter date. The IRS asks you not to call until 60 days after that date, and only if you have not received your refund or heard from it by then.

Find the date printed on your notice or letter. The paper notice and the current official IRS instructions control, even where this page differs.

General next steps

  1. If you filed the return, the IRS says you do not need to take any action during the review window.
  2. Review your copy of the return for errors while you wait; the IRS notes you may file an amended return to correct information.
  3. If you did not file the return, the IRS directs you to send a completed Form 14039, Identity Theft Affidavit, because someone may have filed using your information.

Timing

The IRS asks for up to 60 days from the letter date before you contact it. Your letter controls the exact timing.

Questions after reading the letter?

You can ask the Law Office of Alexander Powell, PLLC to consider a consultation about any IRS or tax letter. Requesting a consultation does not make Mr. Powell your lawyer, provide legal advice, or protect a deadline. Representation begins only after a conflict check, after the firm agrees to the matter, and after both sides sign a written engagement agreement.
