Which tax assumptions matter most when comparing annuity options for retirement?

A sensible first step is to use after tax and after fee numbers when comparing options because headline returns or payments can hide the real tradeoff. Compare side by side the proposed annuity with the income already provided by Social Security or pensions and with lower complexity alternatives. For this planning decision, put the decision into a written plan that shows how it affects retirement, taxes, emergency reserves, and other family goals.
