Are there significant differences between them?

I've only used H&R Blocks software, which used to be called TaxCut. I don't know that are significant differences between any of the tax programs. I would think, if you are a Quicken/QuickBooks user, Turbo tax would be a better, more logical choice.

I take a pile of paper to this guy I know and he calls me in a Couple of weeks. I give him a couple hundred bucks and we call it a day.

Well worth my money to save the time I would spend. I have a few tricky things that get done correctly by using an accountant.

Started using a relative years ago who did it for free so got hooked on the process.
