Thank you for your response. I'd love to clarify with an example:
- Today I make a non-deductible contribution of $6k to a traditional IRA. The split between pre-tax and post-tax contributions is 70/30.
- I convert the $6k to a Roth IRA. 70% of the $6k would be taxed. Would that be correct?
As a follow-up, if I filed married jointly with my husband, we could both contribute $6k (total of $12k) and on line 6 of From 8606 we would have to include the aggregate of both our rollover IRAs? He has very little in his rollover IRA, so my assumption is that it would lower our % of after-tax contributions and balance the ratio between pre and after-tax money in our IRAs.
