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" , I9 e, N0 {2 I( H 5 f/ g8 b w& ?7 i5 o6 ?3 B/ B( w1 t% Y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?
