I have used H & R Block tax software for several years now. It's been consistently easy to use for both my federal and state income tax returns. The electronically filing capabilities have saved me many hours of aggravation working on paper returns. I used the online chat option a couple of times to efficiently resolve issues (of my own making!).
Pros: Easy to prepare, Easy to import documents, Fast
Usually a 5-star - I've been using this software well over 10 years. This last year could've been a little better. Job hunting and job-related moving expenses are now deductible for only a chosen few. Instead of the interview first asking if I was one of the privileged, it took me through the whole process to enter in data, then pulled the rug out from under me and let me know that I couldn't take any of those deductions...
I have used H&R Block software for the past 8 years with the knowledge that the software and the support of H&R service give me the best opportunity to minimize my income taxes.
