Converting a traditional IRA to a Roth

[summer2007]

My Dad is 67 and still working and he has a small traditional IRA of around 30k that he would like to convert to a Roth IRA.

I already found out for him that you can't convert a 401k until you retire.

What I wanted to know is if he can convert his traditional IRA to a Roth while he is still working and if he can convert the whole 30k of it this year?

I think he can do this but I wanted to make sure...I figured someone would know this instantly on here!

Thanks

Jim
