I started with a traditional IRA that I contributed the maximum amount to for a few years. Then I get a 401k and started contributing to that. I also continued to contribute to my IRA, but it was no longer tax deductible.
If I end up converting my traditional IRA to a Roth IRA, how would the taxes work for the years where my IRA was not tax deductible? Would I end up being double taxed on that?
