How to Update Your Name With the IRS

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

When you legally change your name, the IRS will not automatically know about it. You must tell them directly, even if Social Security already has your new name. The IRS matches your tax filings to your Social Security number, and if your name on a return does not match what they have in their system, it can delay refunds, trigger notices, or cause problems with tax credits.

The process is straightforward: you file a form, mail it to the IRS, and they update their records. It takes a few weeks. You do not need to wait until you file your next tax return—you can do this right away after your legal name change is final.

Key Takeaways

File Form 8822-B with the IRS to report a name change; mail it to the address listed on the form for your state.
Include your Social Security number, old name, new legal name, and the date the change became official.
The IRS typically processes the form within two to four weeks.
Update Social Security first if you have not already, because the IRS cross-checks with Social Security records.
If you file a tax return before the IRS processes your name change, use your new legal name on the return.

File Form 8822-B with the IRS

Form 8822-B is the official document the IRS uses to record a name change. You can read it from the IRS website (irs.gov) or request a copy by phone at 1-800-829-3676. The form is short—it takes about five minutes to fill out.

On the form, you will enter your Social Security number, your old name, your new legal name, and the date your name change became official (the date a court order was signed or the date your state issued a new birth certificate or marriage license). Sign and date the form, then mail it to the address printed on the form itself—the address changes depending on which state you live in, so check the form before you mail it.

Do not email or fax the form. The IRS requires a mailed original. Use regular mail, not certified mail—certified mail is not necessary and can slow processing.

Gather your legal name change documents

You do not have to send documents with Form 8822-B, but keep them on hand in case the IRS asks. You will need proof that your name change is official and legal. This is usually a court order from a name-change proceeding, a final divorce decree that shows your new name, a marriage certificate, or a new birth certificate.

If the IRS questions your name change, they will contact you and ask you to send a copy of one of these documents. Having them ready means you can respond quickly and avoid delays. Store the originals in a safe place and make photocopies to send if requested.

Update Social Security before or at the same time

The IRS and Social Security share information, so it is easier if both agencies have your new name at the same time. Visit your local Social Security office or call 1-800-772-1213 to report your name change. You will need to bring your legal name change document (court order, marriage certificate, or new birth certificate) and a photo ID.

If you have already updated Social Security, that is fine—the IRS will eventually match the records. But if you have not, updating both at the same time prevents confusion and speeds up the process.

What happens after you mail the form

The IRS processes Form 8822-B within two to four weeks. During that time, your old name is still in their system. If you file a tax return before they process the form, use your new legal name on the return and include your Social Security number. The IRS will match the return to your account using your Social Security number, not your name.

You will not receive a confirmation letter from the IRS when they process the form. If you want to verify that your name has been updated, you can call the IRS at 1-800-829-1040 and speak to a representative. Have your Social Security number ready.

If you file a return before the name change is processed

File your return using your new legal name, even if the IRS still has your old name in their system. The IRS matches returns to accounts by Social Security number first, so the name mismatch will not prevent them from processing your return or sending a refund.

However, the mismatch may trigger a notice asking you to confirm the name change. If you receive one, respond with a copy of your legal name change document. This is routine and does not mean there is a problem with your return.

Updating your name for future tax filings

Once the IRS processes Form 8822-B, use your new name on all future tax returns, W-4 forms, and any other documents you file with the IRS. Make sure your employer has your new name as well, so they report your income under the correct name to Social Security and the IRS.

If you are self-employed or own a business, you may also need to update your name with your state tax agency and the IRS if you have an Employer Identification Number (EIN). Contact your state tax office or the IRS to confirm whether a separate form is needed.

Frequently Asked Questions

Do I have to wait until I file my next tax return to tell the IRS about my name change?

No. You can report the change right away by mailing Form 8822-B. You do not have to wait for tax season. It is actually better to report it early so the IRS has your correct name on file before you file a return.

What if I file a return with my new name before the IRS processes the form?

The return will be processed correctly because the IRS matches returns to accounts using your Social Security number, not your name. You may receive a notice asking you to confirm the name change, but this is normal. Send a copy of your legal name change document and the matter will be resolved.

Can I report my name change online or by phone?

No. The IRS requires Form 8822-B to be mailed. You cannot report a name change through the IRS website, by phone, or by email. You must mail the original form to the address listed on the form itself.

How long does it take the IRS to process the form?

The IRS typically processes Form 8822-B within two to four weeks. During that time, your old name remains in their system. If you need to verify the change was processed, call 1-800-829-1040 after four weeks and provide your Social Security number.

What if I changed my name but have not updated Social Security yet?

You can update both agencies separately, but it is easier to do them at the same time. Visit your local Social Security office or call 1-800-772-1213. Bring your legal name change document and a photo ID. Once Social Security has your new name, the IRS will eventually match the records.
