This is my first year using ProSeries.  I previously used Thomson Reuters UltraTax & also Intuit's Lacerte.  Both were great in handling basis.  From what I understand, ProSeries has refused to make any changes, so my guess is our only option is to find another software that meets our requirements, since the IRS will be putting more responsibilities in our laps that ProSeries will not help with.

I realize Lacerte & UltraTax are very expensive, but I looked at Drake and it appears like they provide everything missing in ProSeries (full basis calculations and integration between 1120-S, 1065 & 1040 modules).  I will be looking at Drake Software after tax season.  Their price seems reasonable too.
