International Tax Online Platform Coming Fall 2024! 

Effective August 1st, 2024, the International Tax Office will no longer require individual appointments or offer group sessions and will move to an online platform for documenting U.S. tax
residency status, determining tax treaty eligibility, and securely exchanging forms and documents.

  • Newly hired employees and stipend recipients will receive an email from within approximately 14 days of their start date requesting they complete their profile in Sprintax Calculus.

    • Please anticipate this activation email and check spam folder if necessary
    • Note that department delays in setting up job and stipend appointments may delay receipt of this notification

  • International Tax Office staff is available to answer questions during virtual Office Hours.  Join us on Tuesdays between 3-3:45. Beginning July 22nd, we will be expanding our office hours availability to include Thursday mornings.  Details will be posted on our website soon.
