  • Complete the CP54 response form to explain the discrepancies.
  • Include copies of documents to substantiate your name and identifying number.

You may want to

  • you recently married and are using your spouse’s last name and you did not contact SSA to update your records,

I sent you my information. When will I get my refund?

Once we receive your response form and verify the information you provided, you should receive your refund in 4 to 6 weeks, if the name and ID number you provided match our records. If you don’t hear from us after 6 weeks, you can check the status of your refund on Where’s My Refund?

Tips for next year

Make sure you file using your name and taxpayer ID number (TIN) that was updated by SSA or IRS.

What to do next

  • Write down the date on the letter today.
  • Look the number up on irs.gov yourself. Don’t trust a link or phone number from anyone else.
  • If it says you owe money or proposes changes to your return, take it to a licensed CPA, EA or tax attorney before that date.
