Purdue University uses a web-based international tax compliance system, called Glacier, to determine the correct tax withholding for non-resident aliens, and for making all tax treaty determinations. The payee enters his/her information in an online format that has logic to determine international tax decisions. The Nonresident Tax Administrator reviews all submissions for completeness however.
All international employees must have a Glacier account, and must receive an access email link from a payroll or employment center staff person to create an account.
