Reference Code on Your WMR?

If you check “Where’s My Refund” (WMR) and see you have a reference code, you should identify the code and see if any action is required.

In many cases, no action is required on your part. One of the most common codes is 9001, which, as you can see, just means you accessed WMR using a different SSN or TIN.  Once the IRS analyzes to ensure no fraud has taken place, you will get your return like normal. If there is an issue, the IRS will typically send you a letter to your mailing address within 90 days stating what the issue was, and any additional information required.

If you have any questions, you can call the IRS directly at 800-829-1040.
