Wow is Revenue Canada ever a bunch of retards.... So I finally figured out why I keep getting charged interest on owing Canada taxes for 2004, even though I payed them. Well it turns out that Revenue Canada thought I was sending them money in advance for the 2005 tax year, and so they credited me X dollars for that year. They didn't think that maybe, just maybe I was paying my taxes for 2004 seeing as the X dollars I sent them was the EXACT amount I owed for 2004. These geniuses deserve a swift kick in the ass and not my tax money.
I can just imagine how intelligently my tax dollars will be spent by these financially savvy folks.
