While the beginning of autumn quarter may seem a bit early to be thinking about taxes, now is the time to be applying for a US taxpayer ID! You’ll need a US taxpayer ID to submit both federal and state tax returns in April and get appropriately paid wage-income by the university. There are two types of US taxpayer IDs: the Social Security Number (SSN) and Individual Taxpayer Identification Number (ITIN) and each have different eligibility requirements.
There are other benefits to get a US taxpayer ID as soon as possible. If you are eligible for a tax treaty (may exempt some forms of income from tax withholding) a US taxpayer ID needs to be assigned to you before treaty benefits can be taken.
Social Security Number / SSN
An SSN is necessary for on-campus wage positions, such as PhD Primary Funding Assignments, supplemental teaching positions, or other hourly on-campus jobs. You will need to have either a current position or offer of employment to apply, and you are eligible to apply for an SSN if you’re within 30 days of employment beginning.
How to apply for an SSN: follow the steps outlined by the Office of International Affairs at https://internationalaffairs.uchicago.edu/ssn#howdoiapply. To apply for an SSN at a Social Security Administration Office, you will need to bring the following documents with you:
- Completed SSN Application Form
- Valid Passport
- F-1 or J-1 Visa sticker
- Printout of current I-94 electronic record
- Valid Form I-20 or DS-2019
- Proof of employment (from the unit you are working in) and work authorization (from OIA)
Please keep in mind that it is very important to apply for an SSN as soon as you are eligible – an SSN is necessary to report W-2 income when filing taxes and you cannot apply for an SSN if you are not physically in the US.
Individual Tax Identification Number / ITIN
But what if you don’t have an on-campus role or offer of employment? Well, this means that, at the moment, you are not eligible to apply for an SSN. Instead, you will apply for an Individual Taxpayer Identification Number or “ITIN”. This is the main option for students receiving all financial support from the university through supplemental / fellowship stipend. To apply for an ITIN, you will need to prepare the following documentation:
- Completed Form W-7 : You must fill this out exactly as the instructions below explain (see samples to the upper-right). This must be an original and cannot be a copy.
- Certified copy of passport biographic page
- Copy of your student visa sticker (F or J)
- Copy of your most recent I-94 Arrival Record
- Copy of your I-20 or DS-2019
- A letter from your department / program stating you are receiving taxable income from the University). Does not need to be original – this can be a copy or email printout.
- Letter from OIA verifying visa status and SSN ineligibility. To request an ITIN support letter, email: international-affairs@uchicago.edu
