    Securing an Individual Taxpayer Identification Number (ITIN) for your spouse is an essential step if they don’t have a Social Security Number.

    An ITIN allows nonresident and resident alien spouses to work, open bank accounts, and file taxes in the United States. So, in this comprehensive guide, I’ll walk you through the entire ITIN application process for your spouse online.

    Let’s get started.

    What is an ITIN and Why Do I Need One for My Spouse?

    An ITIN is a tax processing number issued by the Internal Revenue Service (IRS) to individuals who are required to have a U.S. taxpayer identification number but who do not have, and are not eligible to obtain a Social Security Number (SSN) from the Social Security Administration (SSA).

    ITINs are primarily used by nonresident and resident alien individuals as well as their spouses who need to file tax returns in the U.S. but aren’t eligible for an SSN. If your spouse is not a US citizen or permanent resident, they will need an ITIN to complete the following tasks:

    File a US tax return with you as a married filing jointly or separately. Both spouses need an SSN or ITIN to file a joint tax return.

    Open a bank account. Most banks require an SSN or ITIN for the primary and joint account holders to comply with federal reporting requirements.

    Work in the US. While an ITIN itself doesn’t authorize your spouse to work, they must have an ITIN or SSN to report wages and work authorization to employers for tax purposes.

    Claim child tax credits or deductions. If you’re claiming any dependents on your tax return, including children, your nonresident spouse needs an ITIN.

    So in summary, an ITIN provides your nonresident or resident alien spouse with a valid tax identification number required for income tax reporting, bank accounts, and family tax credits or deductions when filing jointly with you.

    Do I Need Any Documentation to Apply for an ITIN for My Spouse?

    Yes, you’ll need to provide documentation proving your spouse’s identity and foreign status when applying for an ITIN on their behalf. Here are the primary identification documents required:


    This is one of the main identity documents accepted by the IRS. Provide a valid, unexpired passport for your spouse from their country of citizenship.

    National ID Card

    If your spouse does not have a passport, some countries provide national ID cards that are also accepted by the IRS as identification.

    Birth Certificate

    In some cases, you may need to provide your spouse’s original or certified long-form birth certificate along with a photo ID.

    Marriage Certificate

    Provide your original marriage certificate or certified copy as proof of your marital relationship when applying for an ITIN jointly.

    Visa Documentation

    If your spouse has a valid visa in their passport like an F or J visa, include a copy of the visa pages in their passport.

    Make sure to have original documents or certified copies translated to English if not already. Photocopies are not accepted. Gather and prepare this identification documentation before starting the ITIN application process online.
