My first software was in 1992. Parsons Personal Tax Edge cost $19 for unlimited 1040s and $19 for each state program. I had to calculate Keogh contributions by hand. I think 1997 taxes was first with PS.

They were bought by Intuit, and since I had already used Lacerte in other jobs, I chose Pro Series. ( I still laugh at Lacerte's -1 equals zero.)
