ITIN vs SSN: What Hamilton, Ohio Residents Need to Know
Updated June 2026 · By Asal Multi Services · Columbus, OH
Both numbers appear on tax forms, so Hamilton, Ohio filers often assume they are interchangeable. They are not. Here is the clear difference.
Quick Answer
- ✓ SSN = issued by Social Security; for citizens and people authorized to work.
- ✓ ITIN = issued by the IRS; for people who must file taxes but can’t get an SSN.
- ✓ An ITIN is only for taxes — it does not grant work authorization or immigration status.
- ✓ If you qualify for an SSN, get an SSN, not an ITIN.
What each number is for
A Social Security Number is issued by the Social Security Administration to citizens, permanent residents, and others authorized to work. An ITIN (Individual Taxpayer Identification Number) is issued by the IRS so people with a U.S. tax obligation who are not eligible for an SSN can still file returns and be listed on them. The ITIN is purely a tax-processing number.
What an ITIN can and cannot do
An ITIN lets you file a federal tax return, be claimed as a spouse or dependent where eligible, and meet certain reporting requirements. It does not authorize work, provide immigration status, or make you eligible for Social Security benefits.
How to apply for an ITIN
You apply with IRS Form W-7, usually filed with the tax return that creates your requirement, plus proof of identity and foreign status. Because the IRS wants original documents or certified copies, many people use a Certifying Acceptance Agent so they do not have to mail their passport. Verify current requirements on the IRS website.
