I filed taxes jointly with my wife using her ITIN number. She obtained her SSN last year. Should I mail the tax return for 2023 and include a request to rescind the ITIN?

Go to this IRS website and review Question 20 - https://www.irs.gov/individuals/itin-expiration-faqs

Q20: I have a Social Security Number (SSN) and no longer need my ITIN that will be expiring. Do I need to renew my ITIN?

A20: No, you should not renew your ITIN if you have or are eligible for an SSN.  Please notify us that you have obtained an SSN and no longer need the ITIN by visiting a local IRS office or writing a letter explaining that you have now been assigned an SSN and want your tax records combined.  If you write a letter, include your complete name, mailing address, and ITIN along with a copy of your social security card and a copy of the CP 565, Notice of ITIN Assignment, if available.  The IRS will void the ITIN so it cannot be used by anyone in the future and associate all prior tax information filed under the ITIN with the SSN.  Send your letter to: Internal Revenue Service, Austin, TX 73301-0057.
