The mix of carry-forward info & income-tested benefits is difficult to read due to a cluttered and inconsistent layout
Separate the carry-forward and benefit info into separate sections. The carry-forward details are most useful immediately following the tax balance for the year.
The income tested benefits can be grouped together, or even moved to a new page altogether. The months of the benefit year are listed down the left side, and each income-tested credit is in its own column…GST, CCB, CCR, showing the monthly payments and the total for the year.
Provincial benefits (like Ontario’s Trillium benefits) should be shown as well, perhaps in a table of their own after the federal benefits.
