Troubleshooting

Multi-factor Authentication (MFA)

Accessing Your 1042-S in Sprintax

• Tufts Support Services will provide your 1042-S in Sprintax Calculus.
• To streamline the filing process:
  • Use the email address associated with your 1042-S (likely the one receiving this email) when creating your Sprintax Returns account.
  • If you've previously access Sprintax Calculus via Tufts SSO, the password reset function in Sprintax Returns will allow you to create a static password.
  • If your Sprintax Returns account was created with a different username than the email used for Sprintax Calculus, contact TSS.NRA.TaxAnalysis@tufts.edu.
• Alternatively, download your 1042-S from Sprintax Calculus and upload it manually into Sprintax Returns.
• Email Considerations
  • If your Sprintax accounts use a Tufts.edu email, you will lose access after graduation or departure from the university. Please update your email to a non-Tufts address to retain access.

When should I update my Sprintax Calculus Record? 

Updates to your immigration status, residency, certain biographical information, organization's name changes, or obtaining a U.S. tax ID can greatly impact accurate tax withholding or reporting to federal and state government agencies. It's important that you act with urgency, and update all payment or tax records at Tufts within 30 days of when any information has changed (as required by law), which includes Sprintax Calculus.

Examples of required Calculus updates include: extensions to your immigration status, changes in the type of income you or your organization will receive from Harvard, obtaining a new U.S. tax ID number, changes in your country of residency or permanent address, name changes, etc. If any update within Calculus triggers a change to your tax determination or tax forms, you must also submit updated (and signed) tax forms and any updated immigration documents within Calculus's "Document Exchange" for review and processing by the International Payee Tax Compliance Team.

Important Reminders:

• Tufts students must also make update SIS when receiving new SSNs.
• Please do not delete any historical information within Calculus that you provided in a prior submission.
• To expedited access to any 1042-S tax document Tufts may issue to you by March 15th, you must consent to receive your 1042s form electronically by indicating “yes” in Calculus by February 1st.

Is there a fee associated with using Sprintax Calculus with Tufts? 

No. Sprintax Calculus registration is free for payees invited by Tufts. To ensure a free account setup, payees must

1. register via the unique activation link sent to their email address; and
2. use the same email address that receives the activation link to register in Sprintax Calculus.
