I believe there is a special IRS form for showing when income was received during the year. You can pull it up on Turbo Tax, form 2210 I think. So if one is delaying income (IRA withdrawals) until later in the year, that could be used.Isn't it the case that any taxes paid from any IRA withdrawal (whether an RMD) or not are treated as if they were evenly withheld throughout the year? I seem to recall having read that, but don't know if that has changed.
FWIW, I usually take Roth withdrawals early in the year and then IRA withdrawals later in the year. When I use Turbo Tax I make sure there is no computed penalty for late payment of taxes.
