Taxpayers should allow 7 weeks from the mailing date of the Form W-7, for the IRS to notify you of your ITIN application status (9 to 11 weeks if you submit the application during peak processing periods (January 15 through April 30) or if you’re filing from overseas).

Q5: How do I renew an expired ITIN?

A5: To renew an expired ITIN, you must submit a completed Form W-7, Application for IRS Individual Taxpayer Identification Number, and all required identification documents to the IRS. No tax return is required for a renewal application, however if you have filing requirement you should file the return with the renewing application to prevent a delay in your refund. See Q&A 15. Mail the application to Internal Revenue Service, ITIN Operation, P.O. Box 149342, Austin, TX 78714-9342. See Q&A 13 for information if you do not want to mail documents to the IRS.

A6: No, only original of identification documents or certified copies of the documents from the issuing agency will be accepted. See www.irs.gov/ITIN.

Q7: Do I need to renew my ITIN if I won’t be filing a tax return or claim for refund?

A7: No, however, in the future if you file a U.S. tax return or claim for refund, the ITIN (including for a dependent) will need to be renewed at that time.

Q8: I only use my ITIN on information returns, like Forms 1099. If my ITIN expired, do I need to renew it?

If one family member has middle digits 78 or 79, all family members who were issued an ITIN may submit a Form W-7 at the same time.

Q10: Can I renew my ITIN even though my ITIN did not expire, and no one in my family has an ITIN that expired?

A10: Because your ITIN did not expire and there are no tax implications at this time, we ask that you wait and renew your ITIN when it is scheduled to be expired. Only ITINs that expired at the end of 2016 and need to be included on a U.S. tax return in 2017 should be renewed now. To assist taxpayers and minimize burden as much as possible, we are putting in place a rolling renewal schedule. Please visit www.irs.gov/ITIN for the schedule and anticipated timeframe to renew.

Q11: When will the updated Form W-7 and instructions, which includes the renewal information, be available?

Please notify us that you have obtained a SSN and no longer need the ITIN by visiting a local IRS office or writing a letter explaining that you have now been assigned a 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.

Q13: If I do not want to mail my original documents to the IRS when renewing my ITIN, do I have other options?

A13: Yes, In lieu of sending original documentation, you may be eligible to use an IRS authorized Certified Acceptance Agent (CAA) or make an appointment at a designated IRS Taxpayer Assistance Center (TAC) location. To find a local CAA in your area, you can visit www.irs.gov/individuals/acceptance-agent-program or check your local telephone directory for the nearest location. CAAs can authenticate all the identification documents for the primary and secondary applicant. For dependents, they can authenticate the passport and civil birth certificate; however if other identification documents are used, they must send the original or certified copies of those documents directly to the IRS.

Q14: What kind of passport is acceptable for dependents as a stand-alone identification document?

A14: Effective October 1, 2016, only a passport with an entry date into the U.S. will be acceptable as a stand-alone identification document for dependents from countries other than Canada or Mexico or dependents of U.S. military members overseas. Affected applicants will now be required to submit either U.S. medical records for dependents under age 6 or U.S. school records for dependents under age 18, along with the passport. Dependents aged 18 and over can submit a U.S. school records or a rental or bank statement or a utility bill listing the applicant’s name and U.S. address, along with their passport.

A15: Until the ITIN is renewed, a return with an expired ITIN will be processed and treated as timely filed, but it will be processed without any exemptions and/or credits claimed and no refund will be paid at this time. The taxpayer will receive a notice from the IRS explaining the delay in any refund. Once the ITIN is renewed, any exemptions and credits will be processed and any allowed refund will be paid. If the ITIN is not renewed, the taxpayer may be subject to interest and penalties for any tax owed as a result of disallowed exemptions and credits.

Q16: How long will it take for an expired ITIN to be renewed?

A16: Taxpayers should allow 7 weeks from the mailing date of the Form W-7 for the IRS to notify you of your ITIN application status (9 to 11 weeks if you submit the application during peak processing periods (January 15 through April 30) or if you’re filing from overseas).

Once the ITIN is renewed, any exemptions and/or credits previously disallowed will be reconsidered at that time. Until the ITIN is renewed, the taxpayer will be subject to interest and penalties for any tax owed as a result of disallowed exemptions and credits.

Q20: Is an ITIN considered to be issued when the ITIN application and accompanying return are received?

A20: For new ITINs the “issuance date” will be the received date of the Form W-7 application. For renewed ITINs the “issuance date” will be the original date the ITIN was assigned before it expired./p>

Q21: What if an ITIN application is received (without a return) prior to the tax return due date, but the return itself is received after the tax return due date? What would the issuance date be?

A21: The date the tax return is filed does not impact the “issuance date” of the ITIN. The “issuance date” of the ITIN will depend on whether it is a new ITIN or whether the taxpayer already had an ITIN that has expired and they were renewing their ITIN. See Q&A 20.

Q22: Does a taxpayer have to formally file an extension request in order to extend the tax return due date beyond April 15?

A22: Yes.

Q23: What will be the status of the return on “Where’s my refund?” be, if the return is filed with an expired ITIN?

A23: When a return is filed with an expired ITIN, credits are denied, and the math error is generated. “Where’s my refund?” will display a general message that addresses the impact of the math error on the return filed (i.e., whether there has been a refund decrease or there is now a balance due).

Q24: How long will the return be delayed in processing?

A24: It is not possible to provide an exact timeframe for how long the return will be delayed since that would be dependent upon whether it was the ITIN of the primary, secondary, or dependent(s) on the return and which credits are being claimed. A return filed with an expired ITIN will be processed, but any exemptions and/or credits claimed applicable to the expired ITIN will not be allowed. The taxpayer will receive a notice from the IRS explaining the change(s) made to their tax return and that the ITIN must be renewed. Once the ITIN is renewed, any exemptions and/or credits previously disallowed will be reconsidered at that time.

Q25: When an individual renews their ITIN, will they retain the same ITIN or receive a new one?

A25: Once an ITIN is assigned, it belongs to that taxpayer, unless the ITIN has been revoked. When an individual renews their ITIN, the previously assigned number is renewed.

Q26: When will letters be sent out to individuals who need to renew their ITINs for the upcoming filing season?

A26: CP 48 will be mailed between 8/15 and 9/20/2016 to all ITIN holders with middle digits 78 or 79 that were currently being used on a tax return letting them know their ITIN would expire on January 1, 2017.

Q27: Will only one letter be sent per tax return or will a separate letter be sent to each ITIN holder on a return that needs to renew?

A27: When multiple ITIN holders  are identified as currently being used on the same tax return, one  CP48  notice will be  mailed to the primary and secondary taxpayer at the address on the last return the ITINs were present.

Q28: Will it be a general letter (i.e. you or someone in your household) or a personalized letter?

A28: It is a general notice advising them that according to our records, the ITIN for them or someone listed on their tax return is set to expire. The notice also explains what they need to do to renew the ITIN.

Q29: Will the IRS accept an older version of the W-7 that has Renew an Existing ITIN written on it?

If the applicant applies for the ITIN for an Exception reason, they must attach the appropriate supporting documentation. Renewing an ITIN is not an Exception reason.

Q30: What type of documents are CAAs and TAC offices authorized to authenticate for dependents?
