Found two supposed errors that resulted from no information corrected provided in one of the blocks on a W2, which resulted in my having to mail my state return.
I've been using H&R tax software for nearly 10 years and have found it to be very easy to use. I have a fairly straightforward tax situation so their software simplifies the process while eliminating silly mistakes.
I started using a PC based Federal Tax program in 1998 when I used a program from Parson's Technology. Then, in 2005, if I recall, Intuit bought out that program and created TurboTax. I used TurboTax until 2014, until the features offered decreased, mandating upgrading to a higher level, more expensive version. In 2014 I decided I'd had enough! That's when I switched to H&R Block. It's been consistent, thorough, and price stable. After seven years with them, I'm still super pleased!
