今天收到一封CRA的一封来信,来信的内容是"We cannot calculate the amount of the GST/HSTC to which you maybe entitled for July 2015 to April 2016. If you provide the following information, will process it and inform you the result: -your world income, with the amount converted to Canadian dollars, for the period in 2014 before you came to Canada" ; l0 z" ~2 d7 J' m. u% W3 U% s - F- [+ c2 w4 A% C% G; Z. \去年九月份我才来屯里留学的,之前一直在国内上班,应该有5万左右(人民币)的工资。我需要如何回复他们?可以直接在CRA的网上账户操作么?还是必须通过别的方法(寄信,传真或者打电话)跟他们联系?
