My mom is losing a battle with stage 4 cancer. It's incredibly sad and I'm in tears as I write this. But, I am trying to deal with the financial planning aspects of this objectively. Her assets are about $850k in cash and highly appreciated stocks in a taxable account, $1.6M in a pre-tax IRA, and about $50k in several Roth accounts. My brother and I are 50% beneficiaries on all her accounts. He and I both have relatively high incomes, and both live in CA. I'm at the top of the 24% bracket MFJ + 9.3% CA (=33.3%) and he's in the 32% single bracket + 9.3% (=41.3%). She lives in NY state. I ran the numbers looking at the tax impact of that large IRA, and it looks like there is tax savings for us if my mom converts a large portion of that IRA to Roth, up to a ~$1M conversion, due to the difference in state tax rates. I am not certain of how the mechanics of the conversion and resultant taxes would work.
Assuming she dies this year, and she does a large Roth conversion, her estate will have a large (multi-$100k's) tax bill due next April. I think she'll in be in the safe harbor for the large tax bill, due to having low income (~$60k AGI) in 2020, so we would not want to withhold taxes from the conversion to maximize the amount that goes into Roth. My brother and I would get a step-up in basis on half each of the taxable account on the day she dies, which we could sell immediately and invest in a safe investment like a high yield savings account. Then, next year, the executor of her estate (my mom's sister) would prepare her tax return with an accountant, and my brother and I would each send her half of the taxes due from our savings, which she would submit to the IRS along with the return. Depending on the amount of the conversion, we would still each have ~$200k cash left over after covering half the tax bill.
Are there any problems I'm not foreseeing? Of greatest concern would be sending the large checks to the executor and hoping it wouldn't cause any gift tax problems. I suppose we could each try to pay her tax bill online directly to the IRS, but is it even possible to pay someone else's tax bill? I also realize there's a counter-party risk of my brother deciding to not pay his half, but I'm not worried about this. Thanks in advance.
