I have been using TurboTax since the mid-1980s. I have always had accurate results, even when I was doing both my own taxes, my parents taxes (who ran their own small business), and also my brothers taxes (who also had his own small business). Nowadays, I only have to do the most basic of tax returns for myself, but the ease of use of TurboTax still helps me speed through my tax forms. I would never use another tax preparation program!
