The IRS needs your current legal name on file to match your tax returns and Social Security records

When you legally change your name—through marriage, divorce, court order, or any other means—you must notify the IRS so your tax records stay accurate. The IRS matches your name, Social Security number, and income reports from your employer. If your name on file doesn't match what's on your tax return or what Social Security has, the IRS will flag the mismatch and delay processing your return or refund.

You don't need to wait until tax season to make this change. The sooner you update it, the fewer problems you'll face when you file. The process itself is straightforward and costs nothing.

Key Takeaways

  • You must update your name with Social Security first, before notifying the IRS, because the IRS relies on Social Security's records.
  • Form SS-5 is what you file with Social Security to change your name; you'll need your birth certificate, court order, or marriage certificate as proof.
  • Once Social Security updates your record, you can notify the IRS by mailing Form 8822-B along with a copy of your legal name-change document.
  • The IRS processes name changes in about four to six weeks, but Social Security can take longer, so start the process as soon as your legal change is final.
  • If you file a tax return before your name is updated with the IRS, use your current legal name on the return and include a note explaining the recent change.

Update Social Security first—the IRS depends on their records

The IRS cross-checks your name against Social Security Administration (SSA) records. If you change your name with the IRS but not with Social Security, or vice versa, the mismatch will cause problems. Always start with Social Security.

Visit your local Social Security office in person or call 1-800-772-1213 to request Form SS-5 (process for a Social Security Card). You'll need to bring original or certified copies of documents that prove your legal name change. Acceptable documents include a marriage certificate, divorce decree, court order for name change, or adoption papers. You'll also need your birth certificate and a photo ID.

Social Security typically processes name changes within two to four weeks, though it can take longer during busy periods. You'll receive a new Social Security card in the mail with your updated name.

File Form 8822-B with the IRS to update your tax records

Form 8822-B is the official form the IRS uses to change your name on file. You can read it from IRS.gov or request it by calling 1-800-829-3676. The form is short—it asks for your old name, new name, Social Security number, and the date of the change.

Mail the completed form to the IRS address listed in the form's instructions. Include a copy of the document that proves your legal name change: a certified copy of your marriage certificate, divorce decree, court order, or adoption papers. Do not send originals; send copies only.

The IRS processes these changes in about four to six weeks. You don't need to do anything else while you wait. If you need to file a tax return before the change is processed, use your current legal name and include a note on the return explaining that you recently changed your name legally.

What to do if you file a return before your name is updated

If your tax filing important date arrives before the IRS has processed your name change, file your return using your current legal name. Write a brief note on the return or in the space provided explaining that you recently changed your name and include the date of the change.

The IRS will match the return to your Social Security number, so the return will be processed correctly even if the name doesn't match the old name on file yet. Once your name change is processed, your account will be fully updated and future returns will have no issues.

Update your employer and financial institutions too

Changing your name with the IRS and Social Security is only part of the process. You must also notify your employer so they report your income under your correct name on your W-2 form. Contact your company's payroll or human resources department and provide a copy of your legal name-change document.

Update your name with your bank, investment accounts, insurance companies, and any other financial institutions where you have accounts. These organizations use your Social Security number to track your accounts, so the name mismatch won't cause your accounts to be frozen, but updating them prevents confusion and makes record-keeping cleaner.

If you're self-employed or own a business

If you file Schedule C (self-employment income) or own a business, you may need to update your name on your Employer Identification Number (EIN) as well. Call the IRS at 1-800-829-4933 to update your EIN records, or file Form 8822-B and note that it applies to your business account.

If your business name includes your personal name, you'll also need to file a name-change notice with your state's business registration office or Secretary of State. The process varies by state, so contact your state's business division for specific instructions.

Frequently Asked Questions

Do I have to change my name with Social Security before the IRS?

Yes. The IRS relies on Social Security's records to verify your identity and match your tax returns. If you notify the IRS first, the change may not process correctly until Social Security's records are updated. Always start with Social Security.

What if I lost my marriage certificate or court order?

Contact the court that issued the order or the vital records office in the county where you were married. You can request a certified copy for a small fee, usually between $10 and $25. Social Security and the IRS both accept certified copies.

Will changing my name affect my tax refund?

If your refund is already being processed under your old name when you file the change, it may be delayed while the IRS updates your records. If you're expecting a refund, file your name-change forms as soon as possible. If the delay is significant, contact the IRS at 1-800-829-1040 to check the status.

How long does it take for the IRS to process a name change?

The IRS typically processes name changes within four to six weeks. Social Security can take longer, sometimes eight weeks or more during busy periods. You can check the status of your Social Security change by visiting your local office or calling 1-800-772-1213.

What if the IRS still has my old name after I've updated everything?

Call the IRS at 1-800-829-1040 and explain that you've filed Form 8822-B but your account still shows your old name. Have your Social Security number, old name, new name, and the date you filed the form ready. The IRS can manually verify the change and escalate it if needed.
