You may want to

  • Contact the Social Security Administration (SSA) to update your records if you have a social security number (SSN) and any of the following occurred:
  • you recently married and are using your spouse’s last name and have not already contacted SSA,
  • you legally changed your name without contacting SSA, or

I sent you my information. Now what happens?

Once we receive your response form and verify the information you provided, we will update our records accordingly. If you are due a refund and you haven’t heard 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.

Not advice. Not a filing. Verify with a licensed professional. Rules change by year and facts.
