An allowable tax benefit is a filing status or credit on your U.S. federal return that you claim a spouse or dependent for, and it is what lets them apply for an ITIN (Individual Taxpayer Identification Number). There are 7. Without one, the spouse or dependent can get an ITIN only by filing their own tax return.

What is an allowable tax benefit?
An allowable tax benefit is a benefit on a U.S. federal tax return that a spouse or dependent is claimed for. For tax years after December 31, 2017, a spouse or dependent needs one for an ITIN, unless they file their own tax return.
Before 2018, spouses and dependents could be claimed as personal exemptions. That is no longer possible.
Being claimed means more than a name on a page. The spouse or dependent must be listed on an attached U.S. federal tax return, with the schedule or form for the benefit, or with the right box checked.
What are the 7 allowable tax benefits?
The 7 allowable tax benefits are a joint return, head of household, qualifying surviving spouse, and 4 credits: the American opportunity tax credit, premium tax credit, child and dependent care credit, and credit for other dependents.
| # | Benefit | Who it covers | What the attached return needs |
|---|---|---|---|
| 1 | Joint return | Your spouse | Your spouse on a joint return |
| 2 | Head of household (HOH) | A related dependent | HOH box checked, applicant listed as a dependent |
| 3 | Qualifying surviving spouse (QSS) | Your child or stepchild | QSS box checked, applicant listed as a dependent |
| 4 | American opportunity tax credit (AOTC) | A dependent of the taxpayer claiming it | Applicant listed as a dependent on the return and on Form 8863 |
| 5 | Premium tax credit (PTC) | A dependent | Applicant listed as a dependent, plus Form 8962 |
| 6 | Child and dependent care credit (CDCC) | A dependent who is a qualifying person | Applicant listed as a dependent, plus Form 2441 listing them as a qualifying person |
| 7 | Credit for other dependents (ODC) | A dependent who is a U.S. resident or U.S. national | "Credit for other dependents" box checked next to the name |
For a dependent living with you in the U.S., the ODC is often the simplest fit. It needs no extra form or filing status: list the dependent and check the ODC box. The dependent must still prove U.S. residency.
1. Can my spouse get an ITIN through a joint return?
Yes. Your spouse can get an ITIN if you file a joint return with your spouse, or if your spouse files their own return. Your spouse is never considered your dependent, so the dependent-based benefits do not apply.
A spouse who is a nonresident alien needs one more step. Generally, a couple cannot file jointly if either spouse is a nonresident alien at any time during the year.
The fix is a choice. If you are a U.S. citizen or resident at year end, you and your spouse can choose to treat your spouse as a U.S. resident for the entire year and file jointly. The choice stays in effect in later years until ended.
Maria is a U.S. citizen, and her husband, Diego, is not eligible for an SSN. They make the choice, file jointly, and attach Diego's Form W-7 (reason box e) to the front of the return.
2. How does head of household qualify a dependent for an ITIN?
Head of household qualifies a dependent when your attached return checks the HOH filing status box and lists the applicant as a dependent. If the return does not list them, the IRS will not assign or renew the ITIN.
The dependent must be a qualifying child or qualifying relative who is related to you, and must either:
- Have lived with you for more than half the year, including temporary absences, or
- Be your parent (Publication 501 has the full HOH test).
Kwame is unmarried and supports his mother, who lives in Mexico and has no SSN. She never lived with him, but a parent still counts.
His return checks the HOH box and lists her as a dependent, with her Form W-7 on the front. His mother must still pass the Publication 501 dependent tests.
3. How does qualifying surviving spouse qualify a dependent for an ITIN?
Qualifying surviving spouse qualifies a dependent when your attached return checks the QSS filing status box and lists the applicant as a dependent. If the return does not list them, the IRS will not assign or renew the ITIN.
The dependent must be your child or stepchild, not a foster child, who lived with you the entire year, including temporary absences.
Timing decides QSS. For a 2025 return, your spouse must have died in 2023 or 2024, you must not have remarried before the end of 2025, and you must have been entitled to file a joint return for the year your spouse died. In the year of death itself, you can still file jointly.
Ana's husband died in 2023, and she has not remarried. For 2025, her stepson lived with her all year and has no SSN.
Ana files as QSS, lists him as a dependent, and attaches his Form W-7.
4. How does the American opportunity tax credit qualify a dependent for an ITIN?
The AOTC qualifies a dependent when the attached return and Form 8863 both list the applicant as a dependent. The applicant must be a dependent of the taxpayer who claims the AOTC. Publication 970 covers the credit.
Lin claims the AOTC for her daughter's first year of college. Her daughter has no SSN, so Lin lists her on the return and on Form 8863.
5. How does the premium tax credit qualify a dependent for an ITIN?
The PTC qualifies a dependent when the attached return lists the applicant as a dependent and Form 8962 is attached. Publication 974 explains how the PTC itself works.
Raj claims the PTC, and his youngest son has no SSN.
Raj lists his son as a dependent, attaches Form 8962, and puts his son's Form W-7 on the front.
6. How does the child and dependent care credit qualify a dependent for an ITIN?
The CDCC qualifies a dependent when the attached return lists the applicant as a dependent and Form 2441 lists the applicant as a qualifying person (see Publication 503).
The credit does not have to save you money. You can file Form W-7 for a CDCC dependent even if your return has no tax for the CDCC to reduce.
Omar pays a daycare so he can work, and his son has no SSN. Form 2441 is where the son must appear as a qualifying person; the dependent list alone would not do it.
7. How does the credit for other dependents qualify a dependent for an ITIN?
The ODC qualifies a dependent when the attached return lists the applicant as a dependent with the "Credit for other dependents" box checked next to their name. The dependent must be a U.S. resident or U.S. national.
Owing no tax does not block it. You can file Form W-7 for an ODC dependent even if the ODC reduces nothing and Schedule 8812 is not included.
Sofia's nephew lives with her in Texas and has no SSN.
If her return lists him but leaves the ODC box blank, he has no allowable tax benefit. With the box checked, he does.
Is listing a dependent on my return enough to get an ITIN?
No. Listing a dependent on the attached return is not an allowable tax benefit on its own. You also need the ODC box, the HOH or QSS filing status box, or the credit form (Form 8863, 8962, or 2441).
Tax software can miss the ODC box. It might not check "Credit for other dependents" automatically for a dependent with no taxpayer identification number.
Check the box yourself before you print. The IRS enters the ITIN on your return when it issues the ITIN.
Do dependents need proof of U.S. residency?
Yes. Dependents generally need proof of U.S. residency as well as identity documents. The exceptions are dependents of U.S. military personnel stationed overseas, and dependents from Canada or Mexico claimed for any benefit other than the ODC.
Accepted residency proof depends on age:
- Under 6: a U.S. medical record, U.S. school record, U.S. state ID card, or U.S. visa.
- 6 to under 18: a U.S. school record, U.S. state ID card, U.S. driver's license, or U.S. visa.
- 18 or older: a U.S. school record (under age 24 only), U.S. state ID card, U.S. driver's license, U.S. visa, or a U.S. bank statement, rental statement, or utility bill with the name and U.S. address.
A passport with a date of entry into the U.S. can serve instead.
How do you apply for a spouse or dependent ITIN?
You apply by attaching Form W-7 to the front of your U.S. federal tax return and filing both on or before the return's due date. Leave the SSN area blank for each person applying.
- Pick the allowable tax benefit that fits each person.
- Complete the schedule, form, or box on the return for that benefit.
- Fill in Form W-7: box d for a dependent, box e for a spouse. A dependent also gives the relationship, such as parent, child, or grandchild.
- Add identity documents, plus U.S. residency proof for dependents who need it.
- Submit the package by mail, in person at an IRS Taxpayer Assistance Center, or through a Certifying Acceptance Agent.
You can do all of this on your own, and the IRS charges no fee for an ITIN.
A Certifying Acceptance Agent can verify original documents and return them to you immediately, so they do not go to the IRS. For dependents, that covers only passports and birth certificates.
Renewals work the same way: the spouse or dependent must appear on the attached return with the benefit's schedule, form, or ODC box.
What if no allowable tax benefit applies?
If no allowable tax benefit applies, the spouse or dependent can still get an ITIN by filing their own U.S. federal tax return with Form W-7 attached.
If they have no reason to file their own return, they are not eligible for an ITIN for now.
One limit either way: people filing with an ITIN are not eligible for the earned income credit (EIC). A child with an ITIN cannot be counted as a qualifying child for the EIC.
Frequently asked questions
What counts as an allowable tax benefit for an ITIN?
The 7 allowable tax benefits are a joint return, head of household, qualifying surviving spouse, the American opportunity tax credit, the premium tax credit, the child and dependent care credit, and the credit for other dependents.
Can a dependent get an ITIN just by being on my return?
No. A name on the dependent list is not enough by itself. The return also needs the ODC box, a qualifying filing status, or the form for a credit you claim for that person.
Can I get an ITIN for my wife or husband who lives abroad?
Yes, if you file jointly or your spouse files their own return. For a nonresident spouse, a joint return generally requires choosing to treat your spouse as a U.S. resident for the entire year.
Can my parent get an ITIN as my dependent?
Yes, if you claim your parent as a dependent for a benefit such as head of household. Your parent must be a U.S. citizen, U.S. resident alien, U.S. national, or resident of Canada or Mexico, and meet the Publication 501 tests.
Does the credit for other dependents qualify for an ITIN if I owe no tax?
Yes. The ODC still qualifies the dependent for an ITIN when the credit saves you nothing, even if Schedule 8812 is not included.
Why did my tax software leave the credit for other dependents box blank?
Some programs skip that box when a dependent has no SSN or ITIN yet. Tick it by hand before you file.
Does my dependent from Mexico need proof of U.S. residency?
Not always. A dependent from Canada or Mexico needs U.S. residency proof only when claimed for the ODC, not for HOH, QSS, the AOTC, the PTC, or the CDCC.
Which forms go with Form W-7 for a dependent?
That depends on the benefit: Form 8863 for the AOTC, Form 8962 for the PTC, Form 2441 for the CDCC, the ODC box, or the HOH or QSS filing status box.
When did spouses and dependents need an allowable tax benefit for an ITIN?
The rule applies for tax years after December 31, 2017. Before 2018, spouses and dependents could be claimed as personal exemptions.
Can a spouse or dependent renew an ITIN without an allowable tax benefit?
No, unless they file their own return. A renewal follows the same benefit rule as a first application.
