The fiance is 40, and is changing jobs in 2 weeks. He's talking about converting his $18,000 401(k) to a ROTH like it's a no-brainer. About two years ago, he switched jobs and converted that 401(k) to a ROTH (small amount, as it's now worth ~$11,000). We didn't know each other then, and he doesn't remember why he decided to do it. So, what's the advantage? It's not like this is his only opportunity to contribute to his ROTH this year; he's just under the cutoff, and our combined income will still be under once we're married.
Won't following through on this plan mean paying income tax? Perhaps more than necessary? I'm thinking a better idea is to roll it into a tIRA, which I'm under the impression would be sans income tax, then, backdoor ROTH it once he retires, paying very limited income tax.
While frugal and financially educated, the fiance is bored to tears by finances, and would greatly prefer that I take over this responsibility for our family. He takes immediate action on whatever advice I give him on this stuff. So, am I on the right track? What would you do?
