I am a Canadian citizen who just started grad school in New Hampshire on an F-1 form. I receive a stipend through my department. Does anyone know what the IRS tax rate on this should be? So far, it's been ~15%, but I'm seeing online that the standard tax rate for Non-Resident Aliens (including F1 students like me) is 30% unless I qualify for tax treaty. Does anyone know if there is a treaty that would apply to this? Am I still expected to file this income with the CRA?
Thanks!
