ITIN Application Guide for Columbus, Ohio

Updated January 2026 | Asal Multi Services

An Individual Taxpayer Identification Number (ITIN) allows individuals who are not eligible for a Social Security Number to comply with U.S. tax laws. If you live in Columbus, Ohio and need an ITIN, this guide explains the application process step by step.

What is an ITIN?

An ITIN is a 9-digit number issued by the IRS that begins with the number 9. It is formatted like an SSN (9XX-XX-XXXX) and is used exclusively for tax filing purposes. An ITIN does not:

• Authorize work in the United States
• Provide eligibility for Social Security benefits
• Change your immigration status
• Qualify you as a dependent for Earned Income Tax Credit

Who Needs an ITIN?

• Nonresident aliens required to file a U.S. tax return
• U.S. resident aliens filing a tax return (based on days present)
• Dependents or spouses of U.S. citizens/residents
• Dependents or spouses of nonresident visa holders
• Nonresident aliens claiming a tax treaty benefit

How to Apply: Step by Step

1. Complete Form W-7: Fill out IRS Form W-7, Application for IRS Individual Taxpayer Identification Number.
2. Prepare your tax return: You must attach a completed federal tax return to your W-7 application (unless you qualify for an exception).
3. Gather identification documents: You need original documents or certified copies from the issuing agency. A passport is the only standalone document accepted.
4. Submit your application: Mail to the IRS ITIN Operation center, apply in person at an IRS Taxpayer Assistance Center, or use a Certifying Acceptance Agent (CAA).

Accepted Identification Documents

You must provide documents that prove both your identity and foreign status. Acceptable documents include:

• Passport (the only document that proves both identity and foreign status by itself)
• National identification card (with photo, name, address, date of birth)
• U.S. or foreign driver's license
• Birth certificate (for dependents under 18)
• Foreign voter's registration card
• U.S. visa issued by the Department of State
• Civil birth certificate
• Medical records (for dependents under 6)
• School records (for dependents under 18)

ITIN Renewal

ITINs expire if not used on a federal tax return for three consecutive years. ITINs with middle digits 70-88 have been subject to rolling expiration. If your ITIN has expired, you must renew it by submitting Form W-7 with supporting documents before filing your tax return.

Common Mistakes to Avoid

• Submitting photocopies instead of original or certified documents
• Forgetting to attach the tax return
• Not signing Form W-7
• Using an expired ITIN on a tax return
• Applying for an ITIN when eligible for an SSN
