Reminder: Tax Season 2021

March 31, 2022

If you were present in the United States (U.S.) during any part of calendar year 2021 in any immigration status other than B or WT/WB (ESTA), there is at least one tax form (IRS Form 8843) you must file with the U.S. Internal Revenue Service (IRS) this spring. Below is what you should consider in preparation for the coming tax filing season. If you were not in the U.S. at all during 2021, you do not need to complete any tax forms at this year.

  • Review the HIO Tax FAQ and Tax Filing Overview for background on the U.S. tax system and tax filing deadline dates for 2021. 
  • The HIO licenses a software called Sprintax, which will assist all tax nonresidents with their federal and state tax filing. Current students, scholars, and student interns may log in to use Sprintax using their Harvard key. The cost for federal U.S. filings are covered by the Harvard license. State filings for all 50 U.S. states can be done using Sprintax for an additional fee, listed here.
  • All current students, scholars, and student interns at Harvard will receive an email from the HIO in mid-late February providing additional information and instructions to access the Sprintax tax preparation software.
  • If you are no longer an active student or scholar at Harvard and need to file taxes for 2021, please contact the HIO via email ( in late February to request a unique access code to use Sprintax.

This season, Sprintax will be hosting a series of free open tax webinars to provide helpful information around nonresident tax filing obligations. You can find the details and registration links on the HIO's Tax Filing Overview page.
