Basically, as long as you invest in a longevity annuity that meets
certain guidelines and is designated as a QLAC, you can invest
up to $ 125,000 or 25 % of your 401 (k) or IRA account balance (whichever is less), delay receiving payments until as late as
age 85 and get a nice little tax break, namely, you don't have
to include the cost of the QLAC in calculating RMDs, or the required minimum distributions you
generally must start taking from retirement accounts starting at
age 70 1/2.
