If you want to respond
If you received an adjustment notice, you can respond online or by mail with supporting documentation. To respond online:
- Gather the documents that support your claim.
- Make digital copies of your documents. Hint: You can use your smartphone to take and share a clear and legible picture.
- Log in to (or create) your Online Services account.
- Select the ≡ Services menu in the upper left-hand corner of your Account Summary homepage.
- Select Respond to department notice from the expanded menu.
- On the first screen, under the Notice type section, select the option I received a notice about my refund.
- From the drop-down menu, select the form number of your letter. (You can find the form number in the bottom left-hand corner of your letter.)
To respond by mail:
- Follow the mailing instructions on your adjustment notice.
- Send us any documents that support your claim.
If you are entitled to an additional refund amount, we will issue you a separate check for that amount.
If you received a letter other than an account adjustment notice (Form DTF-160 or Form DTF-161), see Respond to a letter requesting additional information to learn what to include in your response.
If you already responded
If you responded to a letter about an adjusted refund, it may take several months to process your response; it takes more time to review a complicated return or one that has missing or inaccurate information. We process responses in the order we receive them.
