So I have a clarification questions about Spouse's IRA. She is a full time mom. So no paycheck. We file a joint return so I guess she could piggyback on my salary to calculate her deductible contribution limits? Either way, the max is $5500. So my question is, will her tIRA contribution be deductible or a non-deductible? If it is non-deductible then I will do a backdoor Roth on her tIRA as well. If it is deductible, can I claim the deduction and convert it to roth IRA? Also, by when should I do this to be able to reflect it on my 2016 tax return? My guess is April 18th this year, but just wanted to confirm.
