There are three great reasons to do your own taxes. The first is you save money. The second is that it really doesn't take a lot more time to do it yourself since tax software can pull most of your information in from last year's return and download many of the accounts you would have to type in. But the most important is that doing your own taxes teaches you the tax code, at least the parts relevant to you, which causes you to make better tax decisions in the future. That said, any year your financial situation changes dramatically is a great year to have a high-quality tax accountant look things over to see what else you could do.
