Pros

“Even in normal Client support of IRS Notices, it makes my life a whole lot easier pulling transcripts, building letters from templates, and addressing my client issues.”
JA

Justin A.

Tax Manager

“I wish I could add "lite" licenses that just allowed my colleagues who only need basic transcripts and letter templates as opposed to forms and financial analysis for full tax resolution work.”
