Sure, but we figure our heirs will be fortunate to inherit whatever we have at that point. We did set up a trust to minimize tax consequences to heirs, but would rather not take money from our portfolio now to pay taxes for heirs.
The point about one spouse passing away sooner and the survivor being taxed as a single is a good one, and something I hadn’t considered. I’ll ask my CPA about that.
My CPA said that because Roth money grows tax free, many investors never tap into it, especially if they have enough assets from other sources to live their desired lifestyle. So Roths are often left for heirs.
OK, if you think you'll leave a lot for heirs, AND they will be in a lower tax bracket then you are now, then maybe it makes sense to not convert. It sounds like this may be your case.
If they aren't going to be in a lower tax bracket, I don't see why you wouldn't go ahead and convert if it's favorable to you, and go ahead and spend some from that Roth. Just because your CPA says many investors don't tap into it doesn't mean you can't. I'll probably tap my Roth before I sell my highly appreciated taxable assets, so I can avoid paying LTCG taxes that my heirs won't have to because of step-up basis on inheriting taxable accounts.
Also consider that after 70 you start paying MRDs, so you may wind up paying a good part of those taxes anyway.
I don't put any importance in delaying paying taxes vs. paying them now. What I look at is, if I wind up draining all of my assets, how will I get the most out of them, considering taxes paid, and return on investments, including the extra return on taxes deferred.
If you want to consider heirs, you can look at the same scenario for how to maximize you money assuming they will drain those assets, which they likely will have to due to inherited RMD rules. It could be, that if their prospects for making income aren't good, that it's better to let them inherit a tIRA and let them pay the taxes at their lower rate, but if they decide to take it as a lump sum they'll get hit hard.
If it comes out better for myself or my heirs to pay some taxes now, I'll do it. It doesn't bother me in the least if I'm spending my money to pay taxes for my heirs, because I'm going to spend whatever I'm going to spend, and with pre-paying taxes I may leave them a little less, but in a better tax situation. So they'll still win, and not at my expense.
If you think you simply won't spend from your Roth because it's tax free growth, then I can't help you. You are no longer making a financial decision.
If I'm missing something, I'd like to learn what.
Wait! You said in post 26 you don't have heirs, and now you're saying you do. I think I just wasted my time. I guess it gave me time to think through the inheritance angle, but I don't think my son will be in a lower tax bracket than I'm in now so I don't think it changes my plan.
