I must be misreading the OP. I took it to mean he/she was considering taking an additional tIRA distribution of cash into taxable account settlement fund (not tIRA settlement fund) instead of reinvesting dividends in his/her tIRA. That might generate different questions and answers to me - comparing capital gains from taxable vs marginal ordinary income bracket. 'Selling something' might have less tax impact than more ordinary income.
+1 Are we both the only ones misreading the OP? I started reading the replies, and they seemed to miss the point. But I was hesitant because it seemed so many were looking at this from a different angle. Am I misreading? Maybe the remaining posts were working off the first few (possibly misguided?) posts
People seem to be responding to the 1st part, which, IMO, is very minor, since for a tIRA, all w/d are taxed as income (barring any non-deductible contributions). So reinvesting divs or not, while doing withdrawals (assuming withdrawals are greater than divs, just means the divs are sitting in cash a while. Probably best to keep them invested, but not much practical difference if that is the case. But then, it seems OP wants to build a cash balance (but is it useful in a tIRA?), so sure, not reinvesting divs will increase the cash balance, that's just a numerical fact.
I have always had the dividends reinvested inside our TIRA funds. I am thinking of changing that and taking the dividends as cash into the settlement fund.
But then OP goes on:
We are 65/63 and have been using withdrawals from our after tax brokerage account for our living expenses (and doing some small Roth conversions from the TIRA) and I am thinking about taking some $$ from the TIRA's going forward.
For me, this is the important part of the OP. At 65/63, not subject to RMDs yet. So it appears
it is a question of choice of taking withdrawals for living expenses from tIRA or their after tax brokerage account.
Well, the entire tIRA w/d will be taxed as income. Any divs from their brokerage account are already taxed, additional sales are only taxed on the gains (not the entire w/d), and that is likely taxed @ 15%. So ~ 7.5% for example, if the cost basis is one half the sales price (IOW, the investment has doubled since purchased). Assuming long term holdings (> 1 year).
So it seems a w/d from tIRA results in more taxes. Isn't that the important part? My advice is to review the tax situation and support living expenses with the taxable brokerage account, spending divs 1st (do NOT reinvest divs in the brokerage account), then selling the highest cost basis holding first, to reduce taxes (unless there are other reasons to sell specific investments).
