RE end of 2015, so we are early in our third year, with 8 years to go before RMD's. About 1/3 of our funds are in after tax accounts. We haven't perfected an "auto pilot" plan yet but we are getting there. The past two years I manually took Int/div/cap gains from the after tax account, supplemented with IRA disbursements, and then filled up the tax bracket with Roth Conversions. Starting this year, we will take a monthly paycheck by automatically selling portions of an after tax bond fund (with very low unrealized cap gains) and having that sent to our checking account. That, combined with the year end cap gains from last year will cover most, if not all, of our needs. Any extra will come out of available cash.
To keep the AA in order, we are buying CD's in the IRA with those distributions, instead of re-investing.
This will leave more room for Roth conversions, before we start SS at FRA. Plan is to convert all of DW's smaller IRA, and then work in mine. We will not avoid the tax torpedo, but may lessen it a bit. We could change our mind on SS, and wait til 70, but I doubt it. At FRA, with SS, our WR will be 1-1.5% of today's assets. If the SHTF in the market, we could start earlier.
Like any plan, it is all subject to change.
YMMV
