ITIN Name Changes: Marriage, Passport Updates, and Renewal

If your name changed after marriage, divorce, or a court order, do not treat that as a first-time ITIN application. First separate the name-record update from the question of whether your existing ITIN needs renewal. If you are renewing and your legal name changed, the IRS requires documentation supporting that change with Form W-7. Source: Form W-7 instructions, name section.

A newly issued passport, by itself, does not tell you which IRS process you need. It may show the same legal name, a changed name, or a different spelling or transliteration. Those are different problems.

Choose the right name-change path

Situation	First action	Avoid
Existing ITIN, same legal name, new passport	Check whether renewal is actually needed and use current documents if applying	Applying for another ITIN just because the passport number changed
Existing ITIN, legal name changed, renewal needed	Prepare the renewal with the name-change evidence and previous ITIN details	Omitting the prior number or prior assigned name
Existing ITIN, legal name changed, no renewal needed	Contact the IRS using your notice or current IRS contact guidance to confirm the name-update procedure	Assuming a renewal application is required for every name update
IRS notice contains a spelling or birthdate error	Compare the notice with the application and contact the IRS about the correction	Inventing a marriage or legal-name-change explanation for a clerical error
Different Latin-alphabet spellings across documents	Establish whether this is a legal change or a document-consistency issue before filing	Picking a preferred spelling without reconciling the evidence

The table combines the W-7 renewal instructions with the IRS guidance to check the name and birthdate on an ITIN assignment notice. It is a routing framework, not a substitute for instructions in your own correspondence. IRS CP565 notice guidance.

Build a chain from the old name to the current name

Keep three sets of information separate: the name previously associated with the ITIN, the current legal name on identity documents, and the evidence explaining the change between them.

For a renewal after a legal name change, the W-7 instructions give examples such as a marriage certificate or court order, which may include a divorce decree. Those records support the change; they do not replace all identity and foreign-status documentation required for the application. Source: Form W-7 instructions.

Illustrative example: an applicant's prior ITIN notice uses a birth surname, while a current passport uses a married surname. The application file should connect the prior assigned name to the current legal name using the relevant legal document. A note saying “new passport” does not explain that connection by itself.

Before submitting, compare:

the current legal name, including the order of family and given names;
the name and number on the prior ITIN notice;
the birth name, where requested;
the name on any attached federal tax return; and
the dates and names on the marriage, divorce, or court documentation.

If documents conflict, resolve the discrepancy before signing. An adviser should not silently alter the legal spelling to make software accept the application.

Where the names go on a renewal application

The current W-7 instructions explain the legal-name entry on line 1a, the birth-name entry on line 1b when different, and the previously assigned ITIN and name information on lines 6e and 6f. Review those instructions against the actual form revision you use. Source: Form W-7 instructions, specific line instructions.

The safest review is across documents, not just across form fields. A correctly typed W-7 can still leave an unexplained mismatch with the return or supporting identification. Our W-7 guide for nonresident owners covers the broader application.

Check renewal eligibility separately

An ITIN application still needs a qualifying federal tax purpose, and an applicant who is eligible for an SSN should not apply for an ITIN instead. Generally, a federal tax return accompanies W-7 unless an applicable exception is met. A name change does not waive those requirements. Source: Form W-7 instructions, who must apply and supporting documentation.

Use our ITIN renewal guide to review whether renewal is relevant. If your issue is a name-only update or an IRS error, confirm the correction route before paying for application preparation. Keep copies of correspondence and follow any response deadline on your notice; do not assume a name-update request extends a tax deadline.

Frequently asked questions

Does marriage mean I need a second ITIN?

Do not submit a first-time application simply because your name changed. Identify the existing ITIN, check whether renewal is needed, and use the appropriate IRS name-update or renewal process.

Is a new passport enough for a renewal after a legal name change?

The W-7 instructions require documentation supporting a legal name change when renewing. A new passport should not be treated as a reason to omit that evidence.

Can Form5472 Prep handle every name correction?

The advertised ITIN service includes application preparation, CAA assistance, and renewals. A name-only IRS record correction is a different issue; confirm service fit before ordering rather than assuming every correction is included.

Need a renewal and help checking the document chain? Contact Form5472 Prep about your ITIN situation. State whether you already have an ITIN, whether the legal name changed, and whether you have an IRS notice. Do not include your full ITIN or identity-document images in an initial general inquiry. See the ITIN service page for the application offering.
