Welcome to the International Tax Office’s online appointment system!

In alignment with the University’s efforts to slow the spread of COVID-19, until further notice, all new employee appointments will be conducted remotely, via Zoom.  

If you are an existing employee with an immigration status update or general questions, or if you have already met with our office and need to fill out tax treaty paperwork, please email the International Tax Office, IntlTax@CU.eduWe will respond to your inquiry as soon as we can. 

Thank you for your cooperation!
