I've used computer programs before but they started crashing my computer so we started taking our stuff in to H&R Block. The first year it was $120 for my return because I had to file for 2 years (it wasn't on purpose, but I never got around to doing my taxes after the program I bought crashed my computer, and my taxes were a simple T4 - fill in like 3 spots and you're done...LAZY), DH's was only $40. Then it started going up.
We're going to take our taxes to a Chartered Accountant this year to see if we can get more money back. It'll probably cost us more, but if it saves me having to pay in taxes, I'm all for it, lol.
