Tax Information

Tax Information


Everyone who works at OSU must pay federal and state income taxes. OSU is required to withhold income taxes from your paycheck. After the end of the year, you must complete annual tax forms, which for some students will result in a refund of some of the tax that was withheld. These forms are usually due by April 15 each year. In 2022, the deadline to file for tax returns was extended to April 18. Workshops for international students are available each spring to help with this process. Check the ISS electronic newsletter beginning in January for more information.

Students from certain countries may be able to reduce their tax liability through the benefits of an income tax treaty between the U.S. and their country. IF you qualify for treaty benefits, remember that you must sign Form 8233 each year. Check with the ISS office for assistance with tax treaty benefits. Please note that scholarship, fellowship, awards, travel payment or any other type of payment may increase your tax liabilities.

If you are eligible to work and have a job, you will need a Social Security Number (SSN), which can be obtained from the Social Security Administration. You can learn more about the process of obtaining a SSN HERE.

If you are receiving a scholarship from your academic department that is subject to tax, but you do not have a Social Security Number, you will need an Individual Taxpayer Identification Number (ITIN). You can reach out to Trisha Iyonsi ( at Human Resources to expedite the process.


Tax Treaty


All foreign nationals who receive payments for work, scholarships, travel reimbursement, or honoraria, from Oklahoma State University generally must enter information into the university tax database, called Glacier. New students will have the opportunity to do this after attending the work permit session. This database helps OSU determine how you are to be taxed by the U.S. and the State of Oklahoma.

You may be able to reduce your tax obligations if a tax treaty exists between the U.S. and your home country. The Glacier software will tell you if such treaty is available. If Glacier determines that you are eligible for tax treaty benefits, you will be asked to print a pdf file of a Form 8233 for employment or W-8BEN for a scholarship. Remember that the existence of a treaty does not guarantee that you qualify for an exemption. Certain conditions must be met, and each situation must be reviewed. When you reach out to the ISS office for your International Work Permit, we will help you determine if you qualify for a tax treaty.

Form 8233 is valid for one calendar year, from January 1 to December 31. You should be receiving a reminder by email in late November or early December about renewing your treaty. Your treaty for the next year will not be effective until you sign the Form 8233 and submit it to Trisha Iyonsi, the International Tax Coordinator at Human Resources. She will be available to help you understand your tax obligations and assist you with claiming tax treaty benefits. If you have any questions regarding tax treaty benefits, please reach out to Trisha at
