I should also say that I used autofill extensively last year as a tax volunteer and it was extremely useful, in particular during COVID times.  Many of our clients don't have good tax records, and we can't sit with them (so we can't phone the CRA - which with current wait times would be a joke - to get T slip information relayed to us verbally).  If we have autofill we can get the forms done.  If we don't I don't see how we are going to get it done, for these clients. 

In Interview setup, go to Pension and click the blue arrow. Pick split pension income. Set up what you want there. Before doing this, however, calculate the total tax payable by yourself and spouse with MaxBack. Do the same after setting what you want. I think you'll find that the total tax burden is less with MaxBack.

I believe you are both right. The final return now can be E-filed but E-filing is done by a tax preparation business. Ufile and similar software Netfile and we can't yet netfile a final return. Will have to paper file.
