Dear Liz: My mother is 68. She has had a sizable amount of money in an old work 401(k) for several years now. Unfortunately, it has been stuck in the most conservative low-growth fund for more than 10 years during a time of great stock market growth. If she changed it to a more aggressive fund now, are there tax implications to consider, and would this be an unwise change at her age?
Answer: Ouch. The stock market as measured by the Standard & Poor’s 500 benchmark rose more than 250% in the last decade. Instead of more than tripling her money, her low-growth fund may have barely kept up with inflation.
She can’t get back those lost returns, but she could allocate her money more aggressively without having to worry about triggering taxes. Money in 401(k)s and most other retirement accounts is taxed only when it’s withdrawn.
