Fingerprint cards. Applicants will not submit fingerprint cards as a part of the new Acceptance Agent application process. However, background checks will still be conducted, except for those organizations that are specifically excluded in Revenue Procedure 2006-10.
Important Information to Note:
- All persons listed as a Responsible Party of an Acceptance Agent (AA) or Certifying Acceptance Agent (CAA) must take the Mandatory ITIN training, provide proof of professional/ERO status, if applicable and complete Forensic Document Training (CAAs only). These items must be completed prior to approval into the IRS Acceptance Agent Program. (See “How do I apply to become an Acceptance Agent?”)

“suspense” and “reject” processing rate. (See “Can an Acceptance Agent Agreement be terminated?) 4. Certifying Acceptance Agents (CAAs) can only authenticate documents that are original or certified by the issuing agency as proof of foreign status and identity. CAAs can ONLY authenticate the passport and birth certificate for dependents. CAAs cannot authenticate foreign military identification cards. (See in Part 6, “Can I accept “copies” of the applicant’s original documents to support their claim of “identity” and “foreign status”?) 5. Form W-7(COA) must be submitted with each Form W-7 submitted by a CAA. We will not accept substitutions to this form on CAA letterhead. (See “What is a “Certificate of Accuracy”?”) 6. All ITIN applications (including those submitted by Acceptance Agents), must have a valid U.S. Federal income tax return attached. ITINs will not be assigned prior to the taxpayer filing a valid U.S. Federal income tax return (Form 1040, 1040A, 1040EZ, 1040-NR, 1040-EZ or 1040X), unless an exception to the tax return filing requirement is met (See What are the five exceptions to the tax return filing requirement?) 7. All Form W-7s submitted under Exception criteria, require supplemental documentation to prove Exception criteria. (See Exhibit C – Exceptions to the Tax Return Filing Requirement) 8. Because of the Tax Cuts and Jobs Act (TCJA) of 2017, the deduction for personal exemptions was suspended for tax years 2018 through 2025. As a result, spouses and dependents are not eligible to apply for or renew an ITIN, unless they are claimed for an allowable tax benefit or are filing their own federal tax return. The individual must be listed on an attached U.S. federal tax return with the schedule or form that applies to the allowable tax benefit. (See "What is an allowable tax benefit?") 9. All Form W-7 applicants entering the U.S. with a green card or visa that permits them to obtain employment in the U.S. must first apply for a Social Security Number (SSN). If the Social Security Administration (SSA) will not issue an SSN, a letter of denial must be obtained and attached to the Form W-7. This requirement remains the
same if you are requesting an ITIN under an Exception. (See What are the documentation requirements when applying for an ITIN?) 10. A passport is a stand-alone document for proof of identity and foreign status only. Copies of a passport must include the U.S. visa pages if a visa is required for the Form W-7 application. Note: A passport that doesn’t have a date of entry into the United States will no longer be accepted as a stand-alone identification document for certain dependents. If you submit an original valid passport (or certified copy of a valid passport), you do not need to submit a combination of at least two or more other current documents from the list on Exhibit A. (See What are the documentation requirements when applying for an ITIN?) 11. The entry date in the U.S. (Line 6d, Form W-7) must contain the complete date on which an individual entered the United States for the purpose for which they are requesting an ITIN. The date should be entered in month/day/year format (mm/dd/yyyy). If they never entered the U.S. enter “Never entered the U.S.” on this line. (See Part 3- Line 6d. Identification Documents) 12. All Powers of Attorney (POAs) must be submitted to the IRS in English. POAs received in a foreign language will be considered invalid unless accompanied by a certified English translation. (See What are the procedures for IRS communication?) 13. If your client moves before they receive their ITIN, they should send a letter to the ITIN Operation that includes the previous and current addresses. (See What should I do if I have not received the client’s ITIN by the end of the 7-week period?) 14. You may not e-file a tax return(s) using an ITIN in the year in which it is received. If your client applies for and receives an ITIN this year, they may not e-file any tax return (including prior year returns) using that ITIN, until next year. (See in Part 6, “Can I e-file a tax return with an ITIN?”) 15. Your client’s ITIN may expire. For additional information, (See “When will the taxpayer’s ITIN expire?”)
What is an ITIN?
An ITIN (Individual Taxpayer Identification Number) is a tax processing number, issued by the Internal Revenue Service, for certain resident and nonresident aliens, their spouses, and their dependents. An ITIN is only available
6 Acceptance Agents Guide
to individuals who are required to have a taxpayer identification number for tax purposes, but who do not have, and are not eligible to obtain, a Social Security Number (SSN) from the Social Security Administration (SSA). It is a nine-digit number beginning with the number “9”, has a range of numbers from “50” to “65”, “70” to “88”, “90” to “92” and “94” to “99” for the fourth and fifth digits and is formatted like a SSN (i.e. XXXXX-XXXX). ITINs are issued regardless of immigration status because both resident and nonresident aliens may have United States federal tax filing and payment responsibilities under the Internal Revenue Code.
Only individuals who are required to file a U.S. federal income return, or who file a tax return to claim a refund of over-withheld tax are eligible to receive an ITIN.
How does an individual request an ITIN on behalf of a deceased taxpayer?
When an ITIN is requested for a deceased taxpayer, the word “Deceased” and the date of death should be written across the top of the Form W-7. In addition to meeting all of the requirements in the Instructions for Form W-7 for obtaining an ITIN, additional documentation to substantiate the death of the individual must be provided pursuant to the chart below.

date of entry is submitted.
How does a taxpayer apply for an ITIN/EIN?
A taxpayer who needs an ITIN must complete Form W-7 (Application for IRS Individual Taxpayer Identification Number) and submit it to the Internal Revenue Service along with a valid U.S. federal income tax return (unless an exception to the tax return filing requirement is met. For your convenience, you can access fillable Form W-7 at https://www.irs.gov/pub/irs-pdf/fw7.pdf, complete, print then sign the Form W-7.

Should spouses and dependents apply for or renew their ITINs?
For tax years 2018 through 2025, spouses and dependents should not apply for or renew an ITIN unless they are claimed for an allowable tax benefit, or if they file their own tax return. The individual must be listed on an attached U.S. individual federal tax return with the schedule or form that applies to the allowable tax benefit.
What is an allowable tax benefit?
For tax years after December 31, 2017, spouses and dependents are NOT eligible for an ITIN or to renew an ITIN unless they are claimed for an allowable tax benefit or they file their own tax return. Spouses and dependents must be listed on an attached U.S. federal tax return and include the schedule or form that applies to the allowable tax benefit. An allowable tax benefit includes a spouse filing a joint return, head of household (HOH), Qualifying Surviving

When will the taxpayer's ITIN expire? If your ITIN wasn't included on at least one U.S. federal tax return for the last three consecutive tax years, it will expire on December 31st of the third consecutive tax
year, and must be renewed before being used again on a U.S. federal tax return. If your ITIN was assigned before 2013 and was never renewed, you'll need to submit a renewal application with your U.S. federal tax return.
How does a taxpayer renew an ITIN? An ITIN only needs to be renewed if it’ll be included on a U.S. federal tax return and it’s expired. Taxpayers must complete Form W-7/W-7(SP) and submit it to the Internal Revenue Service along with supporting documentation to substantiate their identity and foreign status, and U.S. residency if applicable. Individuals renewing an ITIN must also include a U.S. federal tax return unless they meet an exception. Renewing applicants must use the most current version of Form W-7 to avoid delays in processing. For your convenience, you can access fillable Form W-7 at https://www.irs.gov/pub/irs-pdf/fw7.pdf, complete, print then sign the Form W-7.
