I have a traditional IRA with Vanguard that were rollovers from previous employers. Due to my filing status of married filing separately, I cannot contribute to a Roth IRA this year. I would like to do a backdoor Roth, but wondering if this is possible as I've been told you cannot mix post-tax and pre-tax money in the same pot without penalty. Since it will quickly moved from a traditional IRA to the Roth, would I still get penalized and/or have an tax repercussions? I can't seem to get a clear answer on this (also, I'm a newbie). We've already done a backdoor Roth under my husband's name, but it was easier as he doesn't have a traditional or roth IRA.
