sorry to hear that, we are now able to Efile every newcomer return,  Sometimes it takes couple of tries as Middle name, tried putting in with last name then put it in right under where you mark taxpayer filing first time.

If you do need to paperfile, make sure to add the rejected Efile message that say you can paperfile otherwise there may be penalty for paperfiling if you Efile number.

Can you give me example of how an exact name is written on SIN without giving my the SIN number

First Name

Middle Name

Family Name
