SSN or ITIN
Your SSN identifies you for work, wages and taxes. If you can't get an SSN, an ITIN is used only for filing taxes.
- Who it's for
- SSN: people authorized to work in the U.S. ITIN: people who need to file taxes and can't get an SSN.
- Where
- SSN: start at ssa.gov and finish at a Social Security office. ITIN: by mail to the IRS, at a Taxpayer Assistance Center, a VITA site or an Acceptance Agent.
- What they usually ask for
- SSN: valid passport
- SSN: immigration document (I-94, EAD or Green Card)
- SSN: birth certificate, if you have it
- ITIN: Form W-7 with your tax return
- ITIN: passport or other ID accepted by the IRS
TipThe SSN is free. Wait about 10 days after arriving to apply. An ITIN can also be free at an IRS office or VITA site; a paid agent only saves you from mailing your passport.
