To assist with U.S. tax forms, nonresident alien students and employees who are sponsored by CU have the option to use Sprintax Returns software.
All eligible international students and scholars will receive an access code to Sprintax Returns through their CU-affiliated email. If you have not received an access code by March 7, 2026, email intltax@cu.edu [2].
