I am trying to determine the economics of paying tax and having the benefits of a ROTH in 2010. How much of the TIRA should I convert given my current income and current and future tax liabilities? How is my decision affected by future increases in the tax law in 2011, 2012, and beyond? I would like to plug into a software program that deals with this. Everything I have seen only deals with 2009. I need to start planning ASAP, not the end of next year. 😀
