What Is an ITIN, and When Does an Israeli-American Family Need One

An ITIN ⁦(Individual Taxpayer Identification Number)⁩ is a number the IRS issues to someone who owes into the US tax system but isn't eligible for an SSN. The most common case in Israel: an Israeli spouse, without US citizenship, married to a US citizen and filing a joint tax return.

Who actually needs an ITIN

• An Israeli spouse who isn't a US citizen, when filing Married Filing Jointly
• A child who isn't eligible for an SSN but is needed for a specific tax benefit on the parents' return
• Someone with US-source income ⁦(say, rental property)⁩ without being a citizen or resident

Without it, the return isn't accepted

Form W-7, the ITIN application, must be filed attached to the tax return itself, not separately. Without a number for the spouse, the IRS can't process a joint return, and that can get the entire return rejected, not just that one part.

What it opens, and what it doesn't

An ITIN lets you file jointly and claim the benefits that come with it, like the full married standard deduction. It doesn't grant immigration status, doesn't qualify anyone for US Social Security, and doesn't make the spouse a citizen or resident.

How to apply without mailing original documents

Form W-7 can't be filed electronically, and requires mailing it in or going through a Certifying Acceptance Agent, who can verify the original documents ⁦(usually a passport)⁩ without actually sending them to the US. That's the safer route for anyone who doesn't want to mail an original passport internationally.

What if a child doesn't have an SSN yet

Anyone eligible for an SSN ⁦(like a US-citizen child)⁩ shouldn't and can't get an ITIN instead. The ITIN is specifically for someone who isn't eligible for an SSN, not a temporary stand-in until one arrives.
