Q. As a federal law enforcement officer with 25 years of service, can I retire at the age of 47 and withdraw monthly payments from my Thrift Savings Plan balance based on life expectancy without paying a 10 percent penalty? If so, can I change this at 60 years of age to a specific dollar amount monthly payment without a penalty?
A. Yes, as long as they continue, without interruption or error, until you reach age 59½. After that, you may change the payments without penalty. The rules for avoiding the penalty are complex and strict, so you should consult and qualified tax adviser before proceeding.
