+1. Works very well, much easier than making my own spreadsheet, and is always up to date (at least as-of the prior year) with the machination of the tax code.
cheap, but the money I spend for TT (or, probably as good, HR Block "At Home") is among my best purchases all year. Well worth the money. And having it on disk allows year-round "what-iffing" while all my data stays on my own computer.
