While there are a number of online options for preparing taxes, if you prefer to use software installed on your Mac instead of a Web-based app, then there are really only two contenders for your tax prep dollars: H&R Block and Intuit’s TurboTax. While H&R Block Premium has gotten better at hiding the details behind your return, some aspects of the app can still be overwhelming. While some tax preparation may still require you to use a tax professional, these days, professional quality tax preparation is just a few dollars and a download away. But then I found out that the professionals I paid used software similar to what I could buy for my Mac. In the not-so-distant past, the only option I considered for preparing my taxes was paying $250 to sit at a tax prep office while someone went through my numbers. The simple reality of tax preparation software is this: You want to get the greatest possible refund with the least chance of an audit, all without requiring you to be a tax genius.
