"I've used Ask Blue J to help me research tax issues and respond to client questions. Its very helpful to create a high-level summary of a specific tax issue/question and provides links to the source documents.  You can modify the results by asking additional questions to expand on or exclude a topic. You can also have it remove code section references that a client doesn't need to see or even draft the response as an email to a client."

"I love Ask Blue J so far! Most of my career, bonus depreciation has been at 100%, so beyond the basic rules of section 179, my knowledge is lacking. On one of my returns, I need to step up the basis of equipment as part of a 754 election. I needed to know if I could take section 179 on the equipment basis step up. In under 5 minutes I was able to get clear answer, in an easily digestible summary, that I could print to the file for support. Without Ask Blue J, this research would have taken me hours."
