Q. I retired from an air traffic control job at age 53. I am receiving monthly payments based on my life expectancy. I will be age 55 in April. Can I take a partial withdrawal? If not, are there any options? I need to access more funds. Will there be a tax penalty on the amount I have received? Will my partial withdrawal be penalty-free now that I am 55? Are there other options, such as increased monthly payments?
A. You may not take a partial withdrawal once monthly payments have begun. You may increase your monthly payment amount using Form TSP-73 or you may request a final withdrawal, but making any change to the series of substantially equal periodic payments before you reach age 59½ will subject all of your early distributions to the early withdrawal penalty.
The rules for all of this are complicated. You should consult a CPA before proceeding.
