There are many IRS rules and US tax treaties that effect how payments can be made to non-resident alien individuals who receive payments while they are in the US. These could be payments for services performed by employees or independent contractors or scholarship payments to students. This payment information is reportable on either a W-2 or 1042-S tax form. The university has purchased third-party software to facilitate these payments and reporting obligations. In addition, every country has its own tax laws that apply to individuals performing services outside of the US.
