Yes it does. ALL that matters is what tax rate you are paying (AND expect to pay) for money withdrawn. If the 12% bracket is something you rarely see (as in low) then always take advantage of it and then some. Using after tax funds to pay the taxes on a conversion simply increases the amount of the conversion by the tax amount. People live to say they have $2M in their IRAs when the reality is they really only “own” $1.5M of that money. The rest belongs to the IRS. The more of it you can “own” while only giving 12% to the IRS, the better. Unfortunately, the Catch-22 is those that have large IRAs, typically know how to invest, and find that the IRA grows as fast or faster than RMDs reduce it. This is fine if the long term plan was always to leave as much to heirs as possible, but if you actually wanted to USE the money you saved, then it’s a different story.
So if you found yourself in the same predicament as many, you didn’t realize until too late that always deferring taxes for a benefit now, actually meant no benefit later or even could have cost you money! Plenty of people with large IRAs find themselves with more taxable income in retirement with SS, pension, investment, and RMD income than they had while working!! So they saved some small taxes while in the 15% bracket when young and now have to pay to get that same money out, in the 27% bracket after a successful career and retirement.
