I have a Traditional IRA funded with non-deductible funds (in addition to a Roth IRA) and my spouse has a Traditional IRA funded 100% with deductible funds. I'm interested in converting 100% of my TIRA into my Roth IRA (a.k.a. backdoor Roth IRA) and wondering:
Do I need to include my spouse's TIRA in any pro-rata tax computation on the rollover or are my IRA actions unaffected by my spouse's IRA accounts?
We file jointly and my spouse is not covered by any workplace 401(k) or such.
