Thank you!

Have used Turbotax for about 8 or 9 years now. Have used the online version the last 3 or 4 years. No problems with the online version. I think it's cheaper than the CD version too, though I'm not positive...

Which tax program do you incorporate for most clients?

One vendor: CCH Prosystems.
All clients. All fed & state forms & instructions. Tax research, and daily briefings and newsletters. I'll pm you a sample special report you may find interesting.
It does all the forms we need. We have used this since the mid 90's. Widely used in the profession. The system only supports 10 years however. I think the 2009 software install ditched the 1999 program and client data.

We also use one of their integrated business accounting apps (Engagement) that links directly to the tax returns. Works pretty good.
