Instructions to set your option to online delivery, are listed in the FAQs on the Payroll Services website.
Form 1042-S for Non-U.S. Citizens
The Form 1042-S is for non-U.S. citizens and will be available on the Foreign National Information System (FNIS) between mid-February to mid-March if you’ve selected online delivery of this form. You’ll receive an email notification once your 1042-S is posted. If you have not selected online delivery, we will mail the form no later than March 15. Not all non-U.S. citizens will receive a 1042-S form. A non-U.S. citizen may also receive a W-2
Employee's Withholding Certificates (W-4s)
A Form W-4 determines how much tax your employer will withhold from your paycheck. For further information refer to the W-4 page.
Nonresident Alien Information
Since 2010 the university has used Foreign National Information System (FNIS) software to collect and maintain data to determine your nonresident alien vs. resident alien status for tax purposes.
Please complete the online form when requested and return it as soon as possible so Payroll Services can determine your correct tax withholding. Without this information, we will automatically withhold Social Security and Medicare (FICA) tax unless you are exempt through the student FICA exemption process, and we cannot provide you with other tax exemptions which might otherwise be applicable. Email email@example.com with questions.
