Thank you for both of your thoughtful responses. Knowing now that Form 8606 is an individual form, I wanted to inquire about my husband's situation.
For example, he only has $100 in his rollover IRA. If he contributes $6k and then rolls the $6k into a Roth, would any of the $100 remaining in the traditional/rollover IRA be basis for non-deductible traditional IRA contributions? Thanks in advance.
