One of my moved to moved Switzerland in August 2018 on an Onsite assignment. He earned Indian salary until July 2018. Form-16 issued by his Indian employer has only details of his Indian salary. Please suggest which ITR should he file now, how would he disclose his foreign income and how would he claim tax exemption or tax deduction in view of the taxes paid in Switzerland on his foreign salary.
