I agree it all depends on how much you made and what your deductions are .......I think my gross last year(2012) was $43k and after my deductions and write offs I had to pay $3300 which included CPP ....I got smart this year and started paying monthly installments so I wont owe so much at one time cause I refuse to pay interest. I haven't added up what I made for 2013 yet but I was full for most of the year so it will be similar.
