To get an ITIN for a child, parent, or dependent in 2026, you must follow specific IRS protocols to ensure your tax credits are not denied, If you are filing a US tax return and want to claim a family member a child, parent, or relative who does not have a Social Security Number (SSN), that person needs an Individual Taxpayer Identification Number (ITIN). Without a valid ITIN or SSN issued by the return due date, the IRS may disallow certain dependent-related credits or tax benefits tied to that person.
This guide covers exactly who qualifies as a dependent for ITIN purposes, which Form W-7 box to check, what documents you need, and the most common errors that cause applications to be delayed or rejected based on the IRS Form W-7 Instructions (Rev. December 2024), Publication 501 (2025), Publication 519, and IRS Revenue Procedure 2025-32.

Who Qualifies as a Dependent for ITIN Purposes in 2026?
The IRS defines a dependent applicant as “an individual who can be claimed as a dependent on a U.S. federal tax return and isn’t eligible to get an SSN.” (Form W-7 Instructions, Reason box d). For the complete qualifying tests, see Publication 501.
There are two types of dependents: a qualifying child and a qualifying relative.
Qualifying Child
A qualifying child must meet all five of the following tests. See Publication 501 for complete rules and exceptions including foster child rules, disability exceptions, and special military situations.
Relationship: Must be the taxpayer’s son, daughter, stepchild, foster child, brother, sister, half-sibling, stepsibling, or a descendant of any of these such as a grandchild, niece, or nephew.
Age: Must be under 19 at the end of the year and younger than the taxpayer. If a full-time student, under 24 and younger than the taxpayer. No age limit applies if the child is permanently and totally disabled.
Residency: Must have lived with the taxpayer for more than half the tax year. Temporary absences for illness, school, vacation, business, or military service still count as time lived in the home.
Support: Must not have provided more than half of their own financial support for the year.
Joint return: Must not be filing a joint return for the year, except when filing solely to claim a refund of withheld taxes or estimated tax paid, and no tax liability would exist for either spouse on separate returns.
Qualifying Relative
A qualifying relative must meet all four of the following tests. See Publication 501 for the complete rules and exceptions.
Not a qualifying child: Cannot be the qualifying child of the taxpayer or any other taxpayer.
Relationship or household: Must either live with the taxpayer all year as a member of the household, or be related in a specific way including parents, grandparents, aunts, uncles, and certain in-laws who do not need to live with the taxpayer.
Gross income: Must have gross income below the IRS annual threshold. For 2026, this limit is projected to be $5,300 based on inflation adjustments published in IRS Revenue Procedure 2025-32. Verify the final confirmed amount in Publication 501 when it is released for 2026.
Warning on global income: Gross income includes worldwide income, not just US sourced income. If a parent living abroad receives a pension equivalent to $5,301 USD, they fail the gross income test and cannot be claimed as a qualifying relative, even if they have no US tax filing requirement.
Support: The taxpayer must provide more than half of the person’s total support during the year.
Important: Your spouse is never considered your dependent. The IRS states this explicitly in the Form W-7 Instructions (Reason box d).
Which Box Do You Check on Form W-7?
Selecting the wrong box is the single most common cause of dependent ITIN delays and rejections. Use this table to decide:
| If the primary taxpayer is a… | The dependent checks… |
|---|---|
| US citizen | Box d |
| Green Card holder (lawful permanent resident) | Box d |
| Visa holder who HAS met the Substantial Presence Test (resident alien for tax purposes) | Box d |
| Visa holder who has NOT met the Substantial Presence Test (nonresident alien) | Box g |
What is a resident alien?
A resident alien for tax purposes is someone who passes either the green card test or the Substantial Presence Test meaning they have spent enough days in the US across a three-year period to be taxed as a US resident. This is separate from immigration status.
Common mistake:
Many H-1B and F-1 visa holders who have met the Substantial Presence Test incorrectly instruct their dependents to check box g. If the primary taxpayer has met the test and is filing as a resident alien, their dependents use box d, not box g.
Box d Dependent of US citizen or resident alien
When checking box d, you must enter the exact relationship on the dotted line for example, “daughter,” “son,” “parent,” or “grandson.” Do not write “dependent” or “relative” the IRS requires the specific relationship term. You must also include the primary taxpayer’s full name and SSN or ITIN. Leaving the relationship line blank commonly causes rejection or IRS correspondence delays.
Box g Dependent or spouse of a nonresident alien holding a US visa
Applies when the primary taxpayer is a nonresident alien who holds a US visa and has not met the Substantial Presence Test.
Box e Spouse of US citizen or resident alien
For spouses only. A spouse is never a dependent under IRS rules. A nonresident alien spouse claiming an allowable tax benefit uses box e.
Box f Nonresident alien student, professor, or researcher
Applies to the primary applicant in those categories. Dependents of these individuals typically use box g.
What Are the Allowable Tax Benefits in 2026?
For tax years after December 31, 2017, a dependent is not eligible for an ITIN unless they are claimed for an allowable tax benefit on an attached US federal tax return. The IRS explicitly names the following in the Form W-7 Instructions (Rev. December 2024), “Allowable tax benefit” section:
- Credit for Other Dependents (ODC): generally up to $500 per qualifying dependent (confirm 2026 amount in Schedule 8812 instructions)
- Child and Dependent Care Credit (CDCC): for care costs that allow the taxpayer to work or look for work
- American Opportunity Tax Credit (AOTC): for post-secondary education expenses; requires Form 8863 listing the applicant
- Premium Tax Credit (PTC): for health insurance purchased through the Marketplace; requires Form 8962
- Head of Household (HOH): filing status the dependent must also be claimed as a dependent on the return, not just listed
- Qualifying Surviving Spouse (QSS): formerly called qualifying widow(er); for widows and widowers with a dependent child whose spouse died within the prior two years
2026 rule on CTC and EIC: A dependent who only has an ITIN cannot be used to claim the Child Tax Credit (CTC) or the Earned Income Credit (EIC). The CTC requires a qualifying child with a valid SSN issued before the return’s due date. The ODC is the primary credit available for ITIN-holding dependents.
QSS documentation note: If applying for a dependent ITIN to support a QSS filing status, the attached tax return must use QSS as the filing status. The deceased spouse’s name and date of death should be included on the return to substantiate the allowable benefit.
Can You Get an ITIN for a Dependent With Zero Tax Liability?
Yes. The IRS explicitly states in the Form W-7 Instructions (Rev. December 2024):
“Form W-7 can be submitted for a dependent claimed for the child and dependent care credit or credit for other dependents even if the return has no tax to be reduced by those credits.”
For ODC: Attach the tax return with the dependent listed and the “Credit for other dependents” box checked next to their name. The IRS states Schedule 8812 is not required solely to submit the ITIN application if the box is properly checked however, Schedule 8812 will be required when the credit is claimed on the full filed return.
For CDCC: Attach the tax return with the dependent listed and Form 2441 showing the applicant as a qualifying person.
For QSS: You can apply for an ITIN for a dependent child used to qualify for QSS filing status, even if no credit payment results from the return.
What Proof of US Residency Does a Dependent Need?
Most dependents must prove US residency. The IRS has strict age-based rules. The table below is a summary always verify exact requirements in the Form W-7 Instructions, “Proof of U.S. residency for applicants who are dependents” section, and the Medical/School Records Checklist at the end of those instructions.
| Age Group | Accepted Documents |
|---|---|
| Under 6 years old | US medical record, US school record, US state ID, or US visa |
| Ages 6 through 17 | US school record, US state ID, US driver’s license, or US visa |
| Age 18 and older | US school record (if under 24), US state ID, US driver’s license, US visa, or US bank statement, rental statement, or utility bill showing name and US address |
Medical records checklist for children under 6
Medical records must meet all of the following to be accepted:
- Must be on official letterhead and signed or stamped by the medical provider
- Must show the child’s name and date of birth
- Must show a US address
- Must include a date of care within the past 12 months of the application date
- Patient portal printouts are generally not accepted the document must be on official provider letterhead
- Immunization records are only accepted if they are part of a larger medical record on official letterhead
School records are only accepted for dependents under age 24 and must be official US school documents transcripts, enrollment letters, or report cards that include the student’s name and US address.
All documents must be originals or certified copies directly from the issuing agency, including documents certified by US Embassies or Consulates overseas. The IRS generally does not accept notarized copies, except in limited cases involving dependents of US military personnel stationed overseas.
What If the Dependent’s Passport Has No US Entry Stamp?
A passport without a US date of entry stamp is not accepted as a stand alone document for most dependents. Submitting only a stampless passport for a dependent is one of the most common reasons applications are delayed, suspended, or rejected.
If the passport has no entry stamp, submit additional proof of US residency from the age-appropriate list above alongside the passport.
Exceptions additional residency proof not required for:
- Dependents of US military personnel stationed overseas
- Residents of Canada or Mexico claimed for an allowable benefit other than the ODC
Date of entry requirement: Most dependent applicants must enter their date of entry into the United States on Form W-7 when submitting passport documentation. If the applicant has never entered the US, additional residency documentation or a qualifying exception may be required. Applications missing required entry date information may be suspended or rejected.
Can a Dependent Who Has Never Been to the US Get an ITIN?
It depends on the specific benefit being claimed.
For ODC: The dependent must be a US citizen, US national, or US resident alien. A foreign national who has never been to the US generally cannot meet this requirement.
For HOH and CDCC: These benefits have their own qualifying-person rules that may differ. Head of Household has special rules for certain relatives such as parents who do not need to live with the taxpayer. The Child and Dependent Care Credit requires the qualifying person to have lived with the taxpayer for more than half the year and the care to have occurred in the US. Residency proof requirements under the Form W-7 instructions still generally apply even for qualifying relatives. Review Publication 501 and Form 2441 instructions carefully before applying for these benefits with a foreign-resident dependent.
Canada and Mexico residents: A dependent living in Canada or Mexico may qualify in certain cases without meeting the US residency requirement, provided they meet the relationship, income, and support tests and are claimed for an allowable benefit other than the ODC.
Tax treaty situations: Certain US tax treaties may allow specific dependent claims for residents of other countries. These rules are highly country specific and require professional review. See Publication 519 and the IRS tax treaty table at IRS.gov.
In most cases, a foreign national dependent living abroad will not qualify for an ITIN unless a treaty exception or a specific allowable tax benefit applies. Residency proof requirements still generally apply under Form W-7 instructions even for qualifying relatives.
What Documents Prove the Relationship?
The relationship must be stated on Form W-7 (written on the dotted line next to box d or g) and substantiated through the qualifying tests in Publication 501 when the tax return is filed. The following documents are typically used:
- Civil birth certificate required for applicants under 18 who do not provide a valid passport; establishes parent child relationship
- Adoption papers or legal adoption documents required for legally adopted children
- Marriage certificate used when a parent has changed their name after the birth of the child, or to establish step-child relationships
All documents must be originals or certified copies from the issuing agency.
Photo requirement: At least one submitted document must contain a photograph. This requirement is waived for dependents under age 14, and under age 18 if the applicant is a student.
ODC Credit Details for 2026
| Detail | Amount |
|---|---|
| Maximum ODC credit | Generally up to $500 per qualifying dependent |
| Phase-out begins (married filing jointly) | $400,000 |
| Phase-out begins (all other filers) | $200,000 |
| Phase-out rate | $50 reduction per $1,000 above threshold |
These amounts are based on current law. Confirm 2026 inflation adjusted figures in the Schedule 8812 instructions when released for the 2026 tax year.
Residency requirement for ODC: The dependent must be a US citizen, US national, or US resident alien. Foreign national dependents living abroad generally do not qualify.
How Long Does a Dependent ITIN Take in 2026?
| Submission Type | Expected Processing Time |
|---|---|
| Standard (off-peak periods) | Approximately 7 weeks for IRS notification |
| Peak tax season (January 15 – April 30) | 9 to 11 weeks |
| Applications from overseas | 9 to 11 weeks |
These timeframes are published in the Form W-7 Instructions (Rev. December 2024). Actual processing times may be longer during IRS backlogs or high-volume periods. Check current processing times at IRS.gov/ITIN before submitting.
Passport travel warning: If you are mailing your original passport, do not plan international travel for at least 14 weeks after mailing your application. Original documents are returned separately from IRS notices the IRS aims to return them within 60 days of receipt, but they arrive independently of your CP565 notice.
IRS notices you will receive:
- CP565: Your ITIN has been assigned. No further action needed.
- CP566: The IRS needs more information to process your application. Respond by the deadline with the requested documentation.
- CP567: Your ITIN application was rejected. The notice explains why and what you must resubmit.
How to File: Critical Mailing Instructions
Most first-time W-7 applications require paper filing because the dependent does not yet have an ITIN when the return is submitted. Most standard e-file systems cannot process a return with a pending ITIN application.
Step 1: Complete Form W-7 for each dependent applicant.
Step 2: Leave the SSN field blank on the tax return for each person applying for an ITIN.
Step 3: Attach Form W-7 to the front of the tax return. If applying for multiple ITINs on the same return, attach all Forms W-7 to the front of that single return. The IRS instructions explicitly state: “Attach Form W-7 to the front of your tax return.”
Step 4: Do NOT mail to the standard Form 1040 or 1040-NR mailing address. Mail the complete package Form W-7, tax return, and all supporting documents to the IRS ITIN Operation in Austin:
USPS mail: Internal Revenue Service ITIN Operation P.O. Box 149342 Austin, TX 78714-9342
Private delivery service (FedEx, UPS, DHL): Internal Revenue Service ITIN Operation, Mail Stop 6090-AUSC 3651 S. Interregional Hwy 35 Austin, TX 78741-0000
How to Submit Form W-7 for a Dependent
Option 1 Mail to IRS Austin Service Center: Submit the complete package as described above. Some applicants prefer alternatives since original documents are temporarily mailed to the IRS and returned separately after processing.
Option 2 In person at an IRS Taxpayer Assistance Center (TAC): TACs can verify the following documents in person for dependents and return them immediately: passports, national identification cards, and birth certificates. TACs cannot authenticate school records or medical records for dependents those must be mailed to the IRS. Call 844-545-5640 to schedule an appointment. Service is by appointment only.
Option 3 Certifying Acceptance Agent (CAA): Many families prefer CAAs because original documents generally do not need to be mailed to the IRS. A CAA verifies documents, certifies copies, and submits a Certificate of Accuracy. Important limitation: CAAs can only authenticate passports and birth certificates for dependents. Other dependent documents such as school records or medical records must still be mailed to the IRS directly. CAAs operate worldwide. Find one at IRS.gov.
Option 4 US Embassy or Consulate: You can obtain certified copies of your passport at certain US Embassies or Consulates overseas. The IRS accepts these certified copies in place of original documents.
ITIN Renewal Rules for Dependents
If a dependent’s ITIN has not been used on a federal tax return for three consecutive years, it expires at the end of that third year. The three year non use rule is the most common expiration trigger for dependents. An ITIN unused on returns for 2022, 2023, and 2024 became inactive as of December 31, 2025.
To renew, the dependent must submit a new Form W-7 with current supporting documentation. Dependents must generally attach a federal tax return. The Form W-7 Instructions state:
“Spouses and dependents who renew their ITIN to be claimed for an allowable tax benefit must be listed on an attached U.S. federal tax return, along with the schedule or form that applies to the allowable benefit.”
If a return is filed using an expired dependent ITIN, the IRS will process the return but will disallow the associated credits and issue a CP567 notice. You must renew the ITIN and may need to file an amended return to reinstate the credits.
Most Common Issues That Cause Delays or Rejections
These issues are identified in IRS documentation requirements as frequent causes of incomplete or rejected dependent ITIN applications:
No tax return attached: Most dependent applications require an attached return. Submitting Form W-7 without the required attached return or exception documentation will result in rejection for most dependents.
Wrong box checked: Using box d when box g is correct, or vice versa. Refer to the comparison table above before submitting.
Relationship line left blank or incorrectly completed: When checking box d or box g, the exact relationship must be written on the dotted line for example, “daughter,” “son,” or “parent.” Writing “dependent” or “relative” without the specific relationship commonly causes rejection.
Dependent not listed on the return with the correct credit box checked: The dependent must appear on the return with the applicable form, schedule, or qualifying designation completed.
Passport with no US entry stamp and no additional residency proof: Submit the passport plus a second document proving US residency based on the dependent’s age.
Medical or school records that are unclear, blemished, or missing required information: Records must be legible, on official letterhead, signed or stamped by the provider, and show a US address. The information on all documents must exactly match Form W-7 lines 1a, 1b, 4, and 6a.
Missing primary taxpayer SSN or ITIN: Box d requires the full name and SSN or ITIN of the US citizen or resident alien claiming the dependent.
Adult dependent signed by parent: If the dependent is 18 or older, they must generally sign Form W-7 themselves. A parent or other person generally cannot sign for an adult dependent unless valid Power of Attorney or court appointed guardianship documentation is attached.
Frequently Asked Questions
Can I get an ITIN for a newborn baby?
Yes, if the newborn will be claimed for an allowable tax benefit such as the ODC or CDCC. For children under 6, you need a US medical record, US school record, US state ID, or US visa to prove US residency. A civil birth certificate is typically also needed to establish the relationship. Leave the SSN field blank on the tax return and attach Form W-7 to the front.
Can I apply for a dependent ITIN without a passport?
Yes, If no passport is available, submit at least two documents from the IRS list of 13 acceptable documents that together establish identity and foreign status. For example, a US visa plus a national ID card. All documents must be originals or certified copies from the issuing agency.
Can I claim my wife as a dependent?
No, The IRS explicitly states: “Your spouse is never considered your dependent.” A nonresident alien spouse applies under box e, not box d, and uses allowable benefits such as filing a joint return. See Publication 501 and Publication 519 for spouse specific ITIN rules.
Can I claim my parents living abroad as dependents?
Possibly, but it depends on the benefit. A parent living abroad may qualify as a qualifying relative under Publication 501 if they meet the relationship and support tests. However, the ODC requires the dependent to be a US citizen, US national, or US resident alien which most foreign-resident parents will not meet. CDCC and HOH have their own stricter care and residency rules. Canada and Mexico residents have limited exceptions. Consult a tax professional for your specific situation.
Can a dependent with an ITIN qualify for the Child Tax Credit?
No, The Child Tax Credit requires a qualifying child with a valid SSN issued before the return’s due date. A dependent with an ITIN may qualify for the Credit for Other Dependents (ODC) generally up to $500.
Can I e-file my return while applying for a dependent ITIN?
Most first-time W-7 applications cannot be processed through standard e-file systems because the ITIN does not exist yet. File your return by paper with Form W-7 attached to the front.
What happens if I file with an expired dependent ITIN?
The IRS will process your return but will disallow credits tied to that ITIN and issue a CP567 notice. Renew the ITIN and file an amended return if necessary to reinstate the credits.
How long until I get my passport back after mailing it to the IRS?
The IRS aims to return original documents within 60 days of receipt. They are returned separately from your ITIN notice and your tax refund. Do not plan international travel for at least 14 weeks after mailing if your original passport is included in the package.
