CINTAX Overview

CINTAX is a software program which will allow USC's F-1 and J-1's and their dependents to file to complete their FEDERAL tax forms. 

CINTAX:

  • Calculates the substantial presence test to determine the foreign national's U.S. residency status
  • Checks each type of payment against any applicable tax treaty to ensure that the individual takes advantage of any tax treaty benefits
  • Checks to see if the individual is eligible for "away-from-home" expenses (if he or she) has been in the U.S. for less than 12 months)
  • Completes the correct U.S. income tax form - either Form 1040NR or Form 1040NR-EZ
  • Prepares any additional statements or attachments, as applicable - Form 2106, Form 8843, Schedule C, and/or Scholarship/Fellowship Grant Statement
  • Prints the tax return and all additional attachments (please note, the IRS does not allow nonresident aliens to file a tax return electronically)
  • Provides detailed instructions about how, when and where to submit the tax return, as well as information about the documents necessary to attach and complete the tax return filing process
