[[Can one convert an existing IRA to a ROTH IRA if you are no longer earning income, other from
investments? In other words, can the relavent taxes be paid on an IRA to which one is no longer
eligible to contribute AND then that conventional IRA converted to a ROTH IRA? Would
appreciate answer or opinion!]]

Assuming that you otherwise qualify, there is nothing in the law that would prohibit the conversion/rollover of your regular IRA to a Roth IRA...even without any earned income in the conversion year. Earned income really applies to contributions. Without earned income, you may not make any contributions.

But no restriction on conversions.
