What is Form W-7?
The IRS application for an Individual Taxpayer Identification Number (ITIN)
Form W-7 (Application for IRS Individual Taxpayer Identification Number) is used to apply for an ITIN — a 9-digit tax processing number issued by the IRS to individuals who need a U.S. taxpayer identification number but are not eligible for a Social Security Number (SSN).
An ITIN is a tax tool only. It allows non-residents, foreign nationals, and certain dependents to comply with U.S. tax law, claim treaty benefits, open certain bank accounts, and be claimed as dependents on a U.S. tax return. It does not authorize work, grant immigration status, or qualify anyone for Social Security benefits.
Who Needs Form W-7?
ITIN requirements for non-residents, dependents, and foreign nationals
You Need an ITIN (Form W-7) If:
- Non-resident alien filing a U.S. tax return (Form 1040-NR)
- U.S. resident alien who meets the substantial presence test
- Dependent or spouse of a U.S. citizen or resident alien
- Foreign student or professor on F, J, or M visa filing Form 8843
- Foreign investor receiving U.S. rental or investment income
- Non-resident claiming a tax treaty benefit from the IRS
- Spouse of a non-resident visa holder needing a TIN for a joint return
You Don't Need Form W-7 If:
- You have or are eligible for a Social Security Number
- You are not filing a U.S. federal tax return
- You are visiting the U.S. as a tourist with no U.S. income
- You are an independent contractor paid by a U.S. business (they file 1099-NEC)
- You are a U.S. citizen living abroad — use your SSN
- Your ITIN is already active and not expired
Part I — Reasons for Applying (Boxes a–h)
Check exactly one box — this determines what you must attach to the W-7
Nonresident Alien — Tax Treaty Benefit
You are a nonresident alien required to get an ITIN to claim a tax treaty benefit. Attach Form W-8BEN or the relevant withholding document. A federal tax return is not required for this reason code.
Nonresident Alien Filing a U.S. Tax Return
You earn U.S.-source income and must file Form 1040-NR. Attach your completed federal tax return. The most common reason for foreign contractors working with U.S. clients and foreign investors with U.S. rental income.
U.S. Resident Alien Filing a U.S. Tax Return
You meet the substantial presence test (183+ days in current year based on the 3-year formula) and must file Form 1040. Attach your completed return with the W-7.
Dependent of U.S. Citizen / Resident Alien
A child or other dependent who cannot get an SSN. Attach the U.S. filer's tax return showing the dependent. Dependents claimed for the Child Tax Credit or Other Dependent Credit must meet additional residency requirements. Updated 2024 guidance expanded eligible dependent care credit situations.
Spouse of U.S. Citizen / Resident Alien
You are being claimed as a spouse's exemption on a U.S. tax return or filing jointly. Attach the U.S. spouse's tax return. Used when the foreign spouse does not otherwise have U.S. filing obligations of their own.
Nonresident Alien Student / Professor / Researcher
You are in the U.S. on an F, J, M, or Q visa and need an ITIN either to file a tax return or to claim a tax treaty exemption. Attach Form 8843 if you have no taxable U.S. income, or your 1040-NR if you do.
Dependent / Spouse of Non-Resident Visa Holder
You are the dependent or spouse of someone who holds a non-resident visa (A, G, F, J, etc.) and needs a TIN to be listed on that visa holder's tax return. Attach the primary visa holder's tax return and documentation of the relationship.
Other — Requires Written Explanation
Any situation not covered by reasons a–g. You must provide a detailed explanation of why you need an ITIN. Uncommon in practice — most applicants fit cleanly into b, c, d, or e.
Required Documents
Originals or certified copies only — notarized copies are not accepted
Tier 1 — Standalone (1 document sufficient)
- Passport (any country) — proves both identity and foreign status on its own
- Most recommended: avoids needing a second document and is universally accepted
- Must be current and unexpired
- For dependents under 6: passport or medical records + birth certificate
Tier 2 — Two Documents Required
- At least one must include a photo
- National ID card (with photo and expiration date)
- U.S. or foreign driver's license
- Civil birth certificate (required for dependents under 18)
- U.S. state ID card
- Foreign voter's registration card
- U.S. or foreign military ID card
- Visa issued by U.S. Department of State
- USCIS photo identification
Certifying Acceptance Agent (CAA): Using an IRS-authorized CAA is the safest approach — they certify your documents on the spot so you don't have to mail your passport. The IRS typically returns mailed originals within 60 days, but CAAs eliminate the risk entirely. Find one at IRS.gov/itincaa.
Three Ways to Submit Form W-7
Choose the method that best protects your original documents
Option 1: Mail to IRS Austin Service Center
Send the completed W-7, your tax return (if required), and original or certified documents to the IRS ITIN Operation in Austin, TX. The IRS returns original documents within about 60 days via mail. Use certified mail with tracking — it's your only proof of timely submission.
Address: Internal Revenue Service, Austin Service Center, ITIN Operation, P.O. Box 149342, Austin, TX 78714-9342
Option 2: In Person at IRS Taxpayer Assistance Center
Visit a participating IRS TAC with your original documents. An IRS employee verifies your documents in person, so you take them home same day. Schedule an appointment first — call 844-545-5640. Processing still takes 7–11 weeks from submission date.
Option 3: Through a Certifying Acceptance Agent (CAA) — Recommended
A CAA is an IRS-authorized individual or business who can certify your documents without you mailing them. They verify your identity, certify copies, and often help complete the form. Typical cost: $50–$300. No waiting for document return, reduced rejection risk, expert guidance. Find an authorized CAA at IRS.gov/itincaa.
Common W-7 Mistakes to Avoid
These errors cause rejection and restart the processing clock
Sending Photocopies or Notarized Copies
The IRS requires original documents or copies certified by the issuing agency. Photocopies, notarized copies, and lawyer-certified copies are rejected. Only the organization that issued the document can certify it.
Not Attaching the Required Tax Return
Most applicants (reason codes b, c, e, f, g) must attach a completed federal tax return. The W-7 cannot be processed without it. Only reason codes a, d (some cases), and h have situations where no return is required.
Names Don't Match Across Documents
Your name on the W-7 must exactly match the name on every supporting document. If your passport shows "María José" but your birth certificate shows "Maria Jose" (no accents), include both forms and explain the discrepancy in an attachment.
No Certified Translation for Foreign Language Documents
Documents not in English must include a certified English translation. The translator must certify that the translation is accurate and complete. Typical cost is $20–$100 per document.
Applying During Peak Season Without Extra Time
Standard processing is 7–11 weeks. During peak tax season (January–April), it can stretch to 20 weeks. If you're claiming a dependent's ITIN and waiting for a refund, apply by early December to have the ITIN before tax season deadlines.
Not Renewing an Expired ITIN
ITINs expire if unused for 3 consecutive tax years. Certain older ITINs (with specific middle digits) also expire on a rolling IRS schedule. Using an expired ITIN causes processing delays and rejection of any credits claimed. File Form W-7 for renewal using the same process — mark "Renew Existing ITIN" in Part II.
Frequently Asked Questions
Common questions about Form W-7 and the ITIN application process
How long does it take to get an ITIN?
Standard processing takes 7–11 weeks. During peak tax season (January–April), expect up to 20 weeks. Once approved, the IRS mails a CP 565 letter with your ITIN. If rejected, you receive a CP 567 explaining the reason. You can call 1-800-829-1040 (U.S.) or 1-267-941-1000 (international) to check status — wait at least 7 weeks before calling.
Do I have to mail my original passport?
Only if you apply by mail. The IRS returns original documents within about 60 days via USPS. If you'd rather not risk mailing your passport, use a Certifying Acceptance Agent (CAA) who can certify your passport on the spot, or visit an IRS Taxpayer Assistance Center in person where staff verify documents and return them immediately.
Does an ITIN expire?
Yes. An ITIN expires automatically if it is not used on at least one federal tax return in any of three consecutive tax years. In addition, the IRS has been expiring older ITINs by middle-digit group on a rolling schedule. If your ITIN is expired, renew it by filing a new W-7 marked "Renew Existing ITIN" — you cannot file a valid U.S. return or claim credits with an expired ITIN.
Can I use an ITIN to work in the U.S.?
No. An ITIN is issued solely for federal tax purposes. It does not authorize employment, change immigration status, or make you eligible for Social Security, Medicare, or Earned Income Credit. Only a Social Security Number authorizes work. If you become eligible for an SSN after receiving an ITIN, notify the IRS — your ITIN will be deactivated and your tax history transfers to your SSN.
Can my dependent qualify for the Child Tax Credit with an ITIN?
For the full Child Tax Credit and Additional Child Tax Credit, the qualifying child must have a Social Security Number — an ITIN is not sufficient. However, dependents with ITINs may qualify for the Other Dependent Credit (up to $500) and, per updated 2024 IRS guidance, the Child and Dependent Care Credit in certain situations. Consult a tax professional for dependency situations involving mixed documentation types.
What is the difference between Form W-7 and Form W-9?
Form W-7 is how you apply for an ITIN when you don't have one. Form W-9 is how you provide your existing SSN or ITIN to someone else (a client, bank, or employer) who needs to report payments to you. Once your ITIN is assigned via W-7, you use that number on W-9 forms when clients or businesses request your taxpayer information.
How much does it cost to apply for an ITIN?
The IRS charges no fee to process a W-7 application. However, if you use a Certifying Acceptance Agent (CAA), expect to pay $50–$300 for their services. Certified translations for foreign language documents typically cost $20–$100 each. Applying directly by mail to the IRS Austin Service Center costs nothing beyond postage.

About Form W-7
Form W-7 (Application for IRS Individual Taxpayer Identification Number) is the IRS application for an ITIN — used by non-resident aliens, foreign nationals, dependents, and spouses of U.S. citizens who need a taxpayer identification number but are not eligible for a Social Security Number. The ITIN allows holders to file U.S. tax returns, claim treaty benefits, be listed on joint returns, and meet withholding requirements.
The key to a successful W-7 application is documentation. A valid passport is the only document that satisfies both identity and foreign status requirements on its own. All other combinations require at least two documents. Crucially, only original documents or certified copies from the issuing agency are accepted — notarized copies and photocopies are rejected without appeal.
ITINs expire after three consecutive years of non-use, and the IRS has also been expiring older ITINs with specific middle digits on a rolling schedule. An expired ITIN prevents e-filing and blocks certain credit claims. Renewal uses the same W-7 form with "Renew Existing ITIN" marked in Part II.
