That doesn't make a lot of sense because our deductions come off before we even get to the bottom of page one. Everything from there on is based on the amount we earned AFTER our deductions as in net income not gross income. Then you take things like basic personal expemption off, etc. I don't have a lot of additional deductions other than that as my husband claims most of them including the kids.

Also make sure that she is basing the amount of Canada Pension you owe on the net income and not the gross income too.
