Retirees face crucial decisions on the order of withdrawing funds from 401(k)s, pensions, and Social Security to optimize tax savings and ensure financial security. Priorities vary, with some aiming to leave a legacy for family, while others prioritize enjoying retirement early. Consulting a financial advisor is recommended to align withdrawal strategies with personal goals, such as managing healthcare costs or avoiding outliving savings. Careful planning can prevent excessive taxation and potential depletion of funds.
