Doing my tax return and being asked for info about my late husbands income and his terminal tax return has not been filed yet, now what?

 

Getting started

I am sorry to hear of your loss.
When you don’t know your spouse’s income and can’t find out through reasonable means, the CRA recommends that you enter your best estimate.
