Filing U.S. taxes can be challenging when your child or spouse doesn\u2019t have a Social Security Number, and many families aren\u2019t sure how to include their dependents on the return. The solution lies in applying for an Individual Taxpayer Identification Number (ITIN), a process that ensures your dependents are properly listed, and you continue to receive eligible tax benefits.\u00a0<\/span>\u00a0<\/span><\/p>\n

\u00a0<\/span>Understanding the <\/span>ITIN application<\/span> process can help you file your taxes correctly and avoid unnecessary delays.<\/span>\u00a0<\/span><\/p>\n

\u00a0<\/span>This guide simplifies the ITIN application process for dependents, outlining who qualifies, which documents you\u2019ll need, and how to file accurately, so your application is approved without delays.<\/span>\u00a0<\/span><\/p>\n

<\/span>What Is an ITIN and Why It Matters for Families<\/span><\/b>\u00a0<\/span><\/span><\/h3>\n

An ITIN (Individual Taxpayer Identification Number) is a nine-digit number issued by the Internal Revenue Service (IRS) for individuals who are required to file or be listed on a U.S. tax return but don\u2019t qualify for a Social Security Number (SSN).<\/span>\u00a0<\/span><\/p>\n

\u00a0<\/span>For families, ITINs are often used for:<\/span>\u00a0<\/span>\u00a0<\/span><\/p>\n

\u2022 Nonresident or immigrant spouses who aren\u2019t eligible for an SSN.
\u2022 Dependent children living abroad or without immigration status.
\u2022 Foreign students or relatives claimed as dependents on a U.S. tax return.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n

\u00a0<\/span>Having an <\/span>ITIN number <\/span>allows dependents to be properly included on your tax filing, enabling you to claim credits and deductions you\u2019re entitled to. It also ensures that the IRS can track and process your return correctly.<\/span>\u00a0<\/span><\/p>\n

<\/span>Who Needs an ITIN for Dependents?<\/span><\/b>\u00a0<\/span><\/span><\/h4>\n

Families who claim a child or relative on their U.S. tax return but cannot obtain a Social Security Number (SSN) for them will need to complete an <\/span>ITIN application<\/span>. This ensures the dependent can be properly listed on the tax return, and the family can claim eligible credits or deductions.<\/span>\u00a0<\/span><\/p>\n

\u00a0<\/span>The chart below summarizes the most common dependents who need an ITIN:<\/span>\u00a0<\/span><\/p>\n

\"\"<\/p>\n

<\/span>Who Can Apply for an ITIN<\/span><\/b>\u00a0<\/span><\/span><\/h4>\n

Not every family member automatically qualifies for an ITIN. The applicant must meet specific IRS eligibility criteria, including:<\/span>\u00a0<\/span><\/p>\n

\u2022 Relationship Test:<\/strong> The individual must be your child, stepchild, sibling, parent, or another qualifying relative recognized by the IRS.
\u2022 Residency or Citizenship:<\/strong> They can be a U.S. resident alien or a nonresident living abroad, as long as they meet the IRS dependency requirements.
\u2022 Tax Return Requirement:<\/strong> The person must be listed on a valid federal tax return filed by the taxpayer.
\u2022 Proof of Identity and Foreign Status:<\/strong> You must submit official documents (such as a passport or birth certificate) to verify their identity and nationality.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n

Once these conditions are met, you can confidently complete an <\/span>ITIN application<\/span> for your family member to ensure they are properly included in your tax filings.<\/span>
\n<\/span><\/div>\n<\/div>\n<\/div>\n<\/article>\n

<\/span>Documents Required for Dependent ITIN Application<\/span><\/b>\u00a0<\/span><\/span><\/h4>\n

Before filing, make sure you have all the required documents ready to avoid delays or rejection. Here\u2019s what you\u2019ll need for a complete <\/span>ITIN application<\/span>:<\/span>\u00a0<\/span>\u00a0<\/span><\/p>\n

\u2022 Form W-7:<\/strong> The official IRS form used to apply for an ITIN, requiring a separate submission for each dependent you\u2019re claiming.
\u2022 U.S. Federal Tax Return:<\/strong> Usually Form 1040, where you\u2019ll list your dependent\u2019s details. Attach this return along with the ITIN application unless you qualify for an exception.
\u2022 Proof of Identity and Foreign Status:<\/strong> A passport is the most accepted document because it verifies both identity and nationality. If you don\u2019t have one, provide certified copies of other documents such as a birth certificate, visa, or national ID card.
\u2022 Supporting Documentation for Dependents in the U.S.:<\/strong> For dependents living in the United States, you may also need school or medical records showing their U.S. address to confirm residency.<\/p>\n

\u00a0<\/span>Tip:<\/span><\/b> A passport is the easiest and most reliable proof since it covers both identity and foreign status in a single document.<\/span>\u00a0<\/span><\/p>\n

<\/span>Step-by-Step ITIN Application Process for Dependents<\/span><\/b>\u00a0<\/span><\/span><\/h3>\n

Follow these steps carefully to ensure a smooth <\/span>ITIN application <\/span>process.<\/span>\u00a0<\/span><\/p>\n

\u00a0<\/span>Step 1: Complete Form W-7<\/span><\/b>\u00a0<\/span><\/p>\n

Form W-7, the Application for IRS Individual Taxpayer Identification Number<\/span><\/a>, is available on the IRS website. Complete a separate form for each dependent applying for an <\/span>ITIN number<\/span>.<\/span>\u00a0<\/span><\/p>\n

\u00a0<\/span>When completing the form:<\/span>\u00a0<\/span>\u00a0<\/span><\/p>\n

\u2022 Check box \u201cd\u201d if the dependent is a dependent of a U.S. citizen or resident alien.
\u2022 Provide accurate personal details, including full name, foreign address, and date of birth.
\u2022 Clearly state the reason for applying (for example, \u201cDependent of a U.S. citizen\/resident alien\u201d).
\u2022 Attach a valid federal tax return (Form 1040 or 1040-NR) showing the dependent\u2019s name.
\u2022 If the dependent is under 18, a parent or legal guardian must sign the form on their behalf.<\/p>\n

\u00a0<\/span>Be sure to double-check spelling, birth dates, and identification numbers; even small errors can delay your<\/span> ITIN application<\/span> processing.<\/span>\u00a0<\/span><\/p>\n

\u00a0<\/span>Step 2: Gather Proof of Identity and Foreign Status<\/span><\/b>\u00a0<\/span><\/p>\n

You must prove the dependent\u2019s identity and nationality. The IRS accepts 13 types of documents, but a passport alone is usually enough.<\/span>\u00a0<\/span><\/p>\n

\u00a0<\/span>If you\u2019re not submitting a passport, you\u2019ll need to include at least two of the following:<\/span>\u00a0<\/span>\u00a0<\/span><\/p>\n

\u2022 Birth certificate
\u2022 National ID card
\u2022 U.S. visa
\u2022 Medical or school records (for dependents under 18)
\u2022 Foreign driver\u2019s license<\/p>\n

\u00a0<\/span>All documents must be original or certified copies issued by the appropriate agency since notarized copies are not accepted. Ensuring document accuracy is key to a successful <\/span>ITIN application<\/span>.<\/span>\u00a0<\/span><\/p>\n

\u00a0<\/span>Step 3: Attach the Dependent\u2019s ITIN Application to Your Tax Return<\/span><\/b>\u00a0<\/span><\/p>\n

To process the ITIN, the IRS requires that Form W-7 be submitted along with your tax return (unless you meet an exception).<\/span>\u00a0<\/span><\/p>\n

\u00a0<\/span>When filing:<\/span>\u00a0<\/span><\/p>\n

\u2022 Leave the SSN field blank for each dependent applying for an ITIN.
\u2022 Attach Form W-7 and all supporting documents to the front of your return.
\u2022 If multiple dependents are applying, include a separate Form W-7 for each.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n

This ensures your dependents are officially recognized on your Form 1040 Federal Taxes and U.S. Individual Tax Return<\/a>, allowing you to claim eligible tax benefits such as the Child Tax Credit or other family-related deductions. Knowing how to get an ITIN number and including it correctly can help avoid rejections or tax credit denials.<\/div>\n<\/div>\n<\/div>\n<\/article>\n


\n<\/span>Step 4: Choose How to Submit Your Application<\/span><\/b>\u00a0<\/span><\/p>\n

You can file the dependent <\/span>ITIN application <\/span>using one of three methods:<\/span>\u00a0<\/span>\u00a0<\/span><\/p>\n

1. By Mail:<\/span><\/b>
\nSubmit your Form W-7, tax return, and supporting documents (originals or certified copies) to<\/span>:<\/span><\/p>\n

\u2022 Internal Revenue Service
\u2022 ITIN Operation
\u2022 P.O. Box 149342
\u2022 Austin, TX 78714-9342
\u2022 USA<\/p>\n

\u00a0<\/span>Always use secure and trackable mail.<\/span>\u00a0<\/span>\u00a0<\/span><\/p>\n

2. Through a Certified Acceptance Agent (CAA):<\/span><\/b>
\nA CAA can verify your documents in person so you don\u2019t have to mail the originals. This is a safer and faster option for families.<\/span>\u00a0<\/span>\u00a0<\/span><\/p>\n

3. In-Person Visit to an IRS Taxpayer Assistance Center (TAC)<\/span><\/b>:<\/span><\/b>
\nSchedule an appointment at a local TAC office, where IRS staff can review your application and send it for processing.<\/span>\u00a0<\/span><\/p>\n

\u00a0<\/span>If you\u2019re applying from outside the U.S., contact your nearest U.S. embassy or consulate to check if ITIN services are available.<\/span>\u00a0<\/span><\/p>\n

\u00a0<\/span>Step 5: Wait for Processing<\/span><\/b>\u00a0<\/span><\/p>\n

After submission, the IRS typically takes 7 to 11 weeks to issue an ITIN. During the tax season (January\u2013April), processing may take longer.<\/span>\u00a0<\/span><\/p>\n

\u00a0<\/span>If you haven\u2019t received your dependent\u2019s ITIN after 11 weeks, you can call the <\/span>IRS ITIN hotline at 800-908-9982<\/span><\/b> (or <\/span>267-941-1000 <\/span><\/b>if calling from abroad) for an update.<\/span>\u00a0<\/span><\/p>\n

\u00a0<\/span>Once approved, you\u2019ll receive a letter from the IRS assigning the 9-digit ITIN. Keep this letter safe; you\u2019ll need it for all future filings.<\/span>\u00a0<\/span><\/p>\n

<\/span>Renewing or Updating an ITIN for Dependents<\/span><\/b>\u00a0<\/span><\/span><\/h4>\n

ITINs need to be renewed periodically to stay valid. They expire if:<\/span>\u00a0<\/span>\u00a0<\/span><\/p>\n

\u2022 They haven\u2019t been used on a federal tax return for three consecutive years, or
\u2022 The IRS determines which ITINs are expiring based on their middle digits, the fourth and fifth numbers in the sequence (for example, 9XX-70-XXXX)<\/p>\n

\u00a0<\/span><\/p>\n\n\n\n\n\n\n\n
Middle Digits <\/span><\/b><\/td>\nStatus <\/span><\/b><\/td>\n<\/tr>\n
70,71,72,73,74<\/span><\/td>\nExpired in 2016<\/span><\/td>\n<\/tr>\n
75,76,77,78,79<\/span><\/td>\nExpired in 2017<\/span><\/td>\n<\/tr>\n
80,81,82,83,84<\/span><\/td>\nExpired in 2018<\/span><\/td>\n<\/tr>\n
85,86,87,88,89,90,91,92,93,94,95,96,97,98,99<\/span><\/td>\nExpired in 2020-2023<\/span><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n


\n<\/span>ITINs issued after 2013 and used at least once in the past three years are considered currently valid.<\/span>\u00a0<\/span><\/p>\n

\u00a0<\/span>If your dependent\u2019s <\/span>ITIN application<\/span> has expired or is nearing expiration, follow these steps to renew it:<\/span>\u00a0<\/span>\u00a0<\/span><\/p>\n

\u2022 Fill out Form W-7 again:<\/strong> Select the option \u201cRenew Existing ITIN.\u201d
\u2022 Attach updated documents:<\/strong> Include valid proof of identity and foreign status, such as a passport, birth certificate, or national ID.
\u2022 Skip the tax return if not needed:<\/strong> You don\u2019t need to attach a federal tax return unless you\u2019re updating information or making corrections.
\u2022 Renew early:<\/strong> Submitting your renewal well before tax season helps prevent delays in refunds, credits, or tax processing.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n

\u2022 Submitting notarized copies instead of certified documents. The IRS only accepts original or certified copies from the issuing agency.
\u2022 Forgetting to attach your tax return with Form W-7 unless you qualify for an exception.
\u2022 Using expired identification documents such as passports or ID cards.
\u2022 Entering inconsistent details like name, date of birth, or country of origin.
\u2022 ITIN applications can\u2019t be submitted electronically and must be mailed with a paper tax return.
\u2022 Waiting until tax deadlines to apply, which often leads to processing delays.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n

Pro Tip:<\/span><\/b> Reviewing your <\/span>ITIN application<\/span> with a Certified Acceptance Agent (CAA) can help you avoid errors and speed up approval.<\/span>\u00a0<\/span><\/div>\n<\/div>\n<\/div>\n<\/article>\n

<\/span>FAQs<\/span><\/b><\/span><\/h3>\n

1. Can I apply for an ITIN for a dependent living outside the U.S.?
\n<\/span><\/b>Yes. You can submit an <\/span>ITIN application<\/span> for a dependent living outside the U.S. if they meet <\/span>IRS ITIN<\/span> eligibility rules and are listed on your tax return. The process of <\/span>how to get an ITIN number<\/span> for dependents abroad is the same as within the U.S.<\/span><\/p>\n

2. What documents prove a dependent\u2019s identity and foreign status?
\n<\/span><\/b>A valid passport is the most common document for an <\/span>ITIN application<\/span>. If unavailable, submit a birth certificate, national ID, or school records approved by the IRS to verify identity and foreign status.<\/span><\/p>\n

3. Is it necessary to attach a tax return with the dependent\u2019s ITIN application?
\n<\/span><\/b>Yes. In most cases, a tax return must be included with the <\/span>application for an ITIN<\/span>, unless the dependent qualifies for an exception, such as students or those claiming treaty benefits.<\/span><\/p>\n

4. How long does it typically take to process an ITIN application for dependents?
\n<\/span><\/b>Processing an <\/span>ITIN application<\/span> usually takes 7 to 11 weeks, depending on the time of year and how it\u2019s submitted. To get your <\/span>ITIN number<\/span> faster, ensure all forms and documents are complete.<\/span><\/p>\n

5. How do I renew an expired ITIN for a dependent?
\n<\/span><\/b>To renew a dependent\u2019s ITIN, file Form W-7 again with valid identification documents. A tax return isn\u2019t required for renewal. Following the<\/span> ITIN IRS<\/span><\/b> renewal process keeps your <\/span>ITIN number <\/span>active for future use.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
