Given the complexity of today's practice environment and the worries about Circular 230, etc., doing tax returns on a moonlight basis can be a little dangerous. If you are game, I have heard of small practitioners using some version of TurboTax. Go to Intuit's web site and see what they have in terms of semi-professional type products. Also, look back in this year's archived Journals of Accountancy. Sometime in mid year they always do a comparison of various features. Go to AICPA.org. I have encountered people who join up 3 or 4 practitioners and share a software purchase.
