Student Casual Employees
In order to begin working at a new job on campus, start by filling out all of the required verification and tax documents with your hiring department.
If you are appointed as a Student Officer (e.g., Teaching Assistant, Graduate Research Assistant), please contact your Departmental Administrator for relevant information.
On or Before Your First Day
Introduce yourself to the departmental administrator
You need to make sure the department administrator or human resources representative knows you have been hired in order for your assignment to be processed correctly and for you to be paid on time.
Complete all required new hire paperwork
Your department cannot enter you into payroll, and you will not be paid, until all of your new hire paperwork has been completed and submitted to your department administrator or human resources manager.
The Form I-9 is required for all newly hired employees who will be working in the United States to verify that you are eligible to work in the United States.
As soon as you have accepted your new position, complete Section 1 of the I-9 Form.
Within 3 business days of your start date, visit an I-9 Service Center to complete Form I-9, Section 2. There are I-9 center locations on the Morningside, Manhattanville, CUIMC and Lamont-Doherty campuses.
- Remember to bring the appropriate original documents with you, as listed in Section 1 of the I-9 online. The list of acceptable documents can be found on the USCIS website.
- Please confirm with your department manager what your date of hire is. This is required for the Form I-9.
International Students: If you do not have a Social Security Number (SSN), please refer to the International Student and Scholars (ISSO) website for information on how to apply for one.
All new hires must complete the Federal Form W-4 and state tax forms before receiving a paycheck. These forms provide the University payroll system with the required information to set up the appropriate tax withholding from your paycheck.
- Complete your Federal W-4 Form
- Note: If you are an international student, the IRS has special instructions for Form W4 for nonresident aliens.
- Complete the appropriate New York State tax withholding forms -- IT2104 Form or IT2104.1 Form. Guidance on completing the NY State forms can be found on the New York State Department of Taxation website.
If you are a Non-Resident Alien, you may be eligible for a tax treaty exemption. See IRS Publication 901 on U.S. Tax Treaties to see if your country is listed for students. Questions on your eligibility for a tax treaty benefit and how to complete Form 8233 may be directed to the Human Resources Processing Center (HRPC).

After You Start Working

Please remember you will not get paid if you do not submit a completed timesheet to the appropriate person in the department in which you are working.
Once your hiring paperwork has been completed and you are entered into the University payroll system—People at Columbia (PAC)—we recommend that you sign up for the free direct deposit service. Your paycheck will then be automatically deposited to your back account(s) each payday.
