International Employee

Tax status and completion of tax forms

International employees must comply with the U.S. Tax Code. To ensure compliance, you must make an appointment with the appropriate campus international tax specialist to complete the proper tax forms and establish correct tax status. Please make your appointment as close to your employment start date as possible.  At times, it may be two to four weeks before an international tax specialist can meet with you due to busy academic and tax year schedules.  There is generally no negative ramification to a delay in meeting with our office.

If you’ve reached your 31st day of employment with the university and have applied for but not yet been issued a Social Security number, please have your department payroll representative contact the International Tax Office.
