You can renew your ITIN if it has expired when you file your tax return. You must send a completed Form W-7, Application for IRS Individual Taxpayer Identification Number, along with your U.S. federal tax return, valid supporting original or certified copies by the issuing agency, identification documents, and any other required attachments to renew an expiring ITIN at the address:
ITIN Operation,
Internal Revenue Service,
P.O. Box 149342,
Austin, TX
78714-9342
If your ITIN has expired and you will be filing a federal tax return, you merely need to renew it. The CP565 ITIN Assignment notification contains the ITIN assignment date. If you’ve lost your CP565, call 1-800-829-1040 or 1-267-941-1000, meet the requirements for an ITIN and submit a complete application. You will get a letter from the IRS assigning your tax identification number within approximately up to eleven weeks. You may call 1-800-829-1040 if you have not gotten a response within the specified time frame.
Unless the ITIN has been revoked, the previously allocated number is renewed when an individual renews their ITIN. Suppose you’re renewing your ITIN, and your legal name has changed since your ITIN was issued. In that case, you’ll need to present proof of your legal name change, such as a marriage certificate or a court order, which may include a divorce judgment. Form W-7 should be accompanied by supporting documentation. Taxpayers must use the most recent form of Form W-7 at irs.gov.
The applicant must state that they are renewing their ITIN, offer their ITIN number and name, and explain why they are applying, for example, tax filing obligations. Only the issuing agency’s original or certified copies of identification documents will be accepted.
It’s impossible to say how long the return will be delayed because it depends on whether the ITIN on the return belongs to the primary, secondary, or dependent(s) and whose credits are being claimed. While a return filed with an expired ITIN will be processed, some tax credits and claimed exemptions for the expired ITIN will be denied. The IRS will send the taxpayer a notification outlining the changes made to their tax return and informing them that their ITIN must be renewed. Any previously prohibited exemptions and/or credits will be evaluated when the ITIN is renewed. The taxpayer will be subject to interest and penalties until the ITIN is renewed.
