You can apply for an ITIN without a tax return if your situation fits one of five IRS exceptions, or if you’re a dependent or spouse being claimed on someone else’s return. In every other case, Form W-7 has to be filed together with a federal income tax return. The exception you qualify under decides what paperwork replaces the return.
The Five Exceptions
The default rule is that Form W-7 travels with a Form 1040 or 1040-NR, and the IRS issues the ITIN and processes the return together. The exceptions below are the IRS’s own carve-outs, each numbered and each with its own substitute documentation.
Exception 1: Passive Income With Third-Party Withholding
If you receive U.S.-source passive income and a withholding agent is already withholding tax or reporting the income to the IRS, you can apply without a return. Common cases are interest on a U.S. bank account, partnership distributions, or other investment income subject to reporting.
What you send with Form W-7 depends on the income type:
- Bank account interest: an original letter from the bank on its letterhead confirming the account is subject to IRS reporting or withholding.
- Partnership income: the relevant portion of the partnership agreement showing the employer identification number and your status as a partner.
- Other distributions: a letter from the withholding agent verifying that an ITIN is required to make distributions subject to reporting or withholding during the current tax year.
Exception 2: Wages, Scholarships, or Other Income Under a Treaty
Nonresident alien students, professors, and researchers receiving taxable scholarships, fellowships, or grants can apply without a return. If you’re claiming a tax treaty benefit on that income, expect to include:
- An award letter from the educational institution.
- A copy of the Form W-8BEN submitted to the withholding agent.
- Evidence on Form W-7 that you qualify for treaty benefits.
- Your passport showing a valid U.S. visa.
- A letter from the Social Security Administration confirming you’re ineligible for an SSN.
The same exception covers wages and honoraria. A nonresident alien receiving compensation for services and claiming treaty benefits needs an employment letter or contract from the payer, plus a copy of the completed Form 8233, the withholding exemption form for nonresident aliens.
Exception 3: Mortgage Interest Reporting
If you hold a U.S. mortgage and the lender needs your taxpayer identification number to report mortgage interest to the IRS, you can apply without a return. The lender supplies the supporting documentation.
Exception 4: Sale of U.S. Real Property
Foreign persons selling U.S. real property are subject to withholding under FIRPTA, the Foreign Investment in Real Property Tax Act. You can apply for an ITIN without a return when the buyer or the transferee’s agent needs your taxpayer identification number for withholding. Documentation from the withholding agent or settlement company substantiates this exception.
Exception 5: Treasury Decision 9363
A catch-all covering certain other scenarios where the IRS requires an ITIN for tax administration but no return is being filed. It’s rarely used compared with Exceptions 1 through 4.
Dependents and Spouses of U.S. Citizens or Resident Aliens
A dependent or spouse claimed for a tax benefit can apply for an ITIN without attaching their own return. They still have to appear on a U.S. federal tax return filed by the primary taxpayer, along with the schedule or form for the claimed benefit.
One misconception trips people up here. A child needs a Social Security number to qualify for the Child Tax Credit or Additional Child Tax Credit. An ITIN won’t work for those. What an ITIN does qualify a dependent for is the Credit for Other Dependents, worth up to $500 per dependent.
Identity and Foreign-Status Documents You Still Need
Skipping the tax return doesn’t skip the identity paperwork. Every Form W-7, exception or not, needs documents proving both your identity and your foreign status. A valid passport is the only single document that satisfies both on its own. Without a passport, you need at least two documents from the IRS’s accepted list, and at least one must include a photograph.
Other accepted documents:
- National identification card (must show photo, name, current address, date of birth, and expiration date).
- U.S. or foreign driver’s license.
- Civil birth certificate (required for dependents under 18).
- U.S. state identification card.
- Foreign voter’s registration card.
- U.S. or foreign military identification card.
- Visa.
- USCIS photo identification.
- Medical records (dependents under 6 only).
- School records (dependents under 14, or under 18 if a student).
All documents must be originals or certified copies from the issuing agency. Notarized copies don’t count.
For dependents, the passport rule tightens. A passport without a U.S. entry date stamped in it won’t work as a standalone document for most dependents. The exceptions are dependents of U.S. military personnel stationed overseas and dependents from Canada or Mexico who are claimed for a tax benefit other than the Credit for Other Dependents. Everyone else needs either a passport with a U.S. entry date or additional documents proving U.S. residency.
How to Submit the Application
You have three ways to file, and the choice mostly comes down to whether you’re willing to mail your original documents to the IRS.
By Mail
Send Form W-7, your exception documentation (or tax return, if one applies), and your identity documents to:
Internal Revenue Service
ITIN Operation
P.O. Box 149342
Austin, TX 78714-9342
The obvious cost is that your original passport or other identity documents will be out of your hands for weeks. The IRS returns them, but if you haven’t received them back within 60 days of your ITIN notice, contact the IRS to follow up.
In Person at a Taxpayer Assistance Center
Some IRS Taxpayer Assistance Centers offer in-person ITIN document review. Staff authenticate your originals on the spot and hand them back at the end of the appointment. You still bring a completed Form W-7 and your exception documentation. Appointments are required, and not every TAC location provides the service.
Through a Certifying Acceptance Agent
A Certifying Acceptance Agent (CAA) is authorized by the IRS to verify your identity and foreign-status documents, prepare your Form W-7, and submit the package on your behalf. The CAA authenticates your documents and returns them to you immediately, so nothing original goes to the IRS.
A regular Acceptance Agent, by contrast, can help prepare and mail your application but cannot authenticate documents. With a regular AA, your originals still go to the IRS.
CAA fees typically run from $150 to over $1,000 depending on complexity and location. The IRS website lists authorized agents. If keeping your passport in hand matters, a CAA or a TAC appointment is worth the extra effort.
How Long It Takes
The IRS currently estimates about seven weeks to process an ITIN application. Between January 15 and April 30, or when you apply from overseas, expect nine to eleven weeks. If a return is attached, it won’t be processed until the ITIN is assigned, so applying under an exception without a return can actually be faster on paper because there’s no return sitting in the queue.
Once approved, the IRS mails your ITIN assignment notice, the CP 565, to the address on Form W-7. There’s no online status portal; you call the IRS after the estimated processing window passes.
