How should I enter the name if someone doesn't have a last name? Since both first name an last name are mandatory fields.
The SIN letter states the first name in the last name field and the first name field is blank. I am not able to proceed as both the first name and last name fields are mandatory.
If you are registered with the CRA with only ONE name, then in the last name field put in "Not Applicable" to be able to continue through your tax return.
