Answer
SPRINTAX prepares all the forms necessary to take advantage of a tax treaty between the US and your country of residence. Without the completion of SPRINTAX the maximum amount of federal tax must be withheld from your payment. If you are employed by OSU and do not complete your SPRINTAX profile, the rate of tax to be withheld from your paycheck is set by law at 30%. If you are receiving a scholarship or a fellowship, the rate of tax is set by law at 14%.
