Instructions for Form W-7 (COA), Certificate of Accuracy for IRS Individual Taxpayer Identification Number
What is Form W-7 (COA)
Form W-7 (COA) is a “Certificate of Accuracy” prepared by an ITIN
Certified Acceptance Agent (CAA) and attached to each Form W-7
(Application for IRS Individual Taxpayer Identification Number) that is
submitted to IRS. It contains the following information.
• The name of the designated authorized representative of the CAA who
is completing the Certificate of Accuracy.
• The legal name of the business.
• The EIN (Employers Identification Number) and office code of the
Certified Acceptance Agent.
• The date that the Acceptance Agent Agreement was approved.
• The name of the ITIN Applicant.
• The type(s) of supporting documentation reviewed by the CAA to prove
the ITIN applicant’s “identity” and “foreign status”.
• A statement by the CAA that they have verified to the best of their
knowledge, the authenticity, accuracy and completeness of the
documentation they reviewed.
• The signature of the individual who has prepared the COA and the
date that it was signed.
What is the purpose of Form W-7 (COA)
The COA is a certification by the CAA that they have reviewed the
supporting documentation to prove the ITIN applicant’s “identity” and
“foreign status” and to the best of their knowledge the documents are
complete, authentic, and accurate. Note: With the exception of
documentation to prove Exception 1(a) criteria, the only documents that
should be included in the COA are those that were reviewed by you to
prove the applicant’s claim of identity and foreign status. All other
supplemental documentation supporting “Exception” criteria, (i.e. a copy
of a withholding document, a letter from a financial institution, etc,) as
well as a denial letter from the Social Security Administration (if
applicable) must be attached to Form W-7 and submitted to IRS.
Who must submit a COA?
All IRS ITIN Certified Acceptance Agents are required to complete and
submit a separate COA for each Form W-7 that is sent to IRS. It is
important to remember that as a Certified Acceptance Agent,
documentation to support identity and foreign status must be reviewed
by you and should be included with your COA. You must attach a copy of
the original documents or certified copy by the issuing agency for primary
and secondary applicants. For dependents, you must attach a copy of
the passport or birth certificate. For all other dependent documents, you
must attach the original document or certified copy by the issuing agency.
IRS employees at designated Taxpayer Assistance Centers (TAC) will not
review W-7 applications prepared by CAAs.
Who can sign the Certificate of Accuracy?
Only the designated authorized representative of the business is
permitted to sign the COA.
Where can I find Form W-7 (COA)?
Form W-7 (COA) can be found on the IRS web site at www.irs.gov by
searching for “Form W-7 (COA)”.
Whose PTIN is required?
Only tax practitioners are required to have a PTIN. The approved
authorized representative of the business must provide their PTIN on
Form W-7 (COA).
Supporting Documentation
You should check only the boxes that correspond to the documents which
you reviewed and certified to support the ITIN applicant’s identity and
foreign status. A passport is the only stand alone document for purposes
of satisfying both the “identity” and “foreign status” criteria. For
dependents applying under reason code "d", the passport must have a
date of entry to be a stand-alone document, unless they are from Canada,
Mexico, or are dependents of U.S. military personnel overseas. If the
passport does not have a date of entry, additional original documents
verifying the dependent's U.S. residency are required. See Part 4 of
Publication 4520 for documents accepted as proof of U.S. residency for
dependents. If you review the applicant’s passport, you would place an “x”
in the box under the “Identity” and “Foreign Status” column on the
Passport line. If, however, a passport is not reviewed by you, then a
combination of at least two or more documents must be examined from
the list of Supporting Documents; one which satisfies identity, and one
which satisfies foreign status. If a document does not display a box under
the Identity or Foreign Status column, it signifies that the document can
not be used to support that category. For example: A Foreign Drivers
License, U.S. State Identification Card, and U.S. Military Identification
Card can not be used to prove an applicant’s “foreign status”. Therefore
there is no check-box for those documents under the foreign status
column. They can, however, be used to prove the applicant’s “identity”, so
there are check-boxes under the identity column. Medical records valid for
children under 6 years of age and school records are valid only for
dependents under age 14, (under age 18 if a student).
