ITIN for H-4 Visa Holders: What Spouses on Dependent Visas Need to Know

If you're in the United States on an H-4 visa — the dependent visa for spouses and children of H-1B workers — you may find yourself in an unusual tax situation: you're physically in the U.S., but you can't get a Social Security Number, and you still need a tax ID.

The ITIN is the solution. This guide explains when H-4 holders need one, how the application works, and what's different about applying from inside the U.S.

Who Gets an H-4 Visa

H-4 visas are issued to the immediate family (spouse and unmarried children under 21) of H-1B, H-1B1, H-2A, H-2B, and H-3 visa holders. The most common case: the spouse of an H-1B worker.

H-4 holders are legally present in the U.S. but are not authorized to work (with one significant exception, discussed below). Because they're not authorized to work, they're generally not eligible for a Social Security Number from the Social Security Administration.

When an H-4 Holder Needs an ITIN

Filing Taxes as a Dependent

If a U.S. taxpayer (such as the H-1B spouse) is filing a U.S. tax return and wants to claim the H-4 spouse or H-4 child as a dependent, each dependent needs a TIN. If they don't have an SSN, they need an ITIN.

W-7 reason code:

• Reason d — for H-4 children or other dependents
• Reason e — for H-4 spouse, if the taxpayer is filing Married Filing Jointly (MFJ)
• Reason g — for H-4 spouse or dependents of the H-1B holder in some joint filing scenarios

Married Filing Jointly (MFJ)

If the H-1B taxpayer wants to file jointly with their H-4 spouse, the spouse must be included on the return — and must have a TIN. An H-4 spouse who is a nonresident alien (has not met the Substantial Presence Test) must use an ITIN for the MFJ return.

Note: Nonresident alien spouses can be treated as U.S. residents for tax purposes if an election is made under IRC §6013(g) or §6013(h). This is a common strategy for maximizing the MFJ standard deduction and tax brackets. If this election is made, the ITIN application goes in with Reason e on the W-7.

If the H-4 Holder Has Work Authorization (H-4 EAD)

Some H-4 holders are eligible for Employment Authorization Documents (H-4 EAD) based on their H-1B spouse's status in the green card process. H-4 EAD holders can legally work.

If you have an H-4 EAD: Apply for a Social Security Number, not an ITIN. SSN is the correct identifier for anyone authorized to work in the U.S. The SSA will issue an SSN, which covers all tax filing purposes.

If you don't have an H-4 EAD (or are waiting for it): An ITIN is appropriate. Note that if an SSN is later obtained, the ITIN becomes inactive and the SSN takes over for all future filings.

How H-4 ITIN Applications Differ from Non-Resident Spouse Applications

A common point of confusion: there are two distinct situations that sound similar but follow different pathways.

Non-resident spouse (outside the U.S.): The H-1B holder is in the U.S., their spouse is still abroad, and they want to file MFJ. The spouse applies for an ITIN from overseas, typically via a CAA using video verification. This is the most common scenario covered in general spouse ITIN guides.

H-4 visa holder (already in the U.S.): The spouse is already in the U.S. on H-4. They're a resident or long-term visitor, not a nonresident. The filing situation and W-7 reason code may differ.

Key difference for H-4 holders in the U.S.:

• They may qualify as resident aliens under the Substantial Presence Test if they've been in the U.S. long enough (183+ days under the IRS formula)
• If they're a U.S. resident for tax purposes, the filing involves Form 1040 (not 1040-NR)
• H-4 holders with significant U.S. presence should check whether they need to file as a resident alien — which changes the tax computation significantly

Substantial Presence Test for H-4 Holders

An H-4 holder physically present in the U.S. may meet the Substantial Presence Test and be classified as a U.S. resident for tax purposes. The test counts:

• All days present in the current year
• 1/3 of days present in the prior year
• 1/6 of days present in the year before that

If the total is 183 or more, you're a U.S. resident for tax purposes (unless an exception applies).

H-4 visa is a nonimmigrant visa, but the SPT is not exempt for H-4 holders (unlike F and J visa holders, who are generally "exempt individuals" under IRC §7701(b)(5)). This means H-4 holders who have been in the U.S. for an extended period may be resident aliens for tax purposes and should file Form 1040, not 1040-NR.

If you're a resident alien under SPT:

• You may be eligible for an SSN through some pathways (check with SSA)
• If no SSN is available, apply for an ITIN with Reason c on the W-7 ("U.S. resident alien filing a U.S. federal tax return")
• File Form 1040 (not 1040-NR)

Applying from Inside the U.S.

H-4 holders in the U.S. can apply through:

Option 1: IRS Taxpayer Assistance Center (TAC) IRS TAC offices accept ITIN applications in person. You bring your original passport, Form W-7, and supporting documents. The TAC verifies the passport on the spot and submits the application.

• Find TAC offices: irs.gov/help/tac
• TAC appointments are required; availability varies
• Advantage: no passport mailing, no CAA needed

Option 2: Certified Acceptance Agent (CAA) A CAA can verify the passport in person or via video call and submit the application. This is convenient if you're in an area without a nearby TAC or prefer not to visit an IRS office.

Option 3: Mail with original documents Submit Form W-7 with your original passport to the IRS Austin address. The IRS returns the passport after processing, typically within 60 days.

Document Checklist for H-4 ITIN Application

• Form W-7 (current revision, reason d or e or g checked)
• U.S. tax return (Form 1040 or 1040-NR, as applicable) or Form 1040-NR with the ITIN applicant listed as a dependent
• Identity document: valid passport
• Supporting status document: I-94 printout (uscis.gov/i94) and/or H-4 visa stamp in passport

For a dependent child (Reason d):

• If the child is a minor, the parent signing Form W-7 should indicate their relationship
• If the child has no passport, a birth certificate combined with a school record or medical record may be acceptable — consult a CAA

When the H-4 Holder Gets Work Authorization Later

If an H-4 EAD is subsequently approved and the holder gets a job and applies for an SSN:

1. The SSN supersedes the ITIN
2. The holder files an SSN-based return going forward
3. The IRS will associate the two numbers internally
4. The previous ITIN is not "merged" or "transferred" — it simply becomes inactive
5. No official "cancellation" of the ITIN is required

Inform any employers, financial institutions, and the IRS on future returns that an SSN is now being used instead of the ITIN.
