Q. I will be retiring in May with 25 years of federal law enforcement service. I will be 50 years old and subject to penalties and taxes on a one-time, age-based partial withdrawal from my Thrift Savings Plan. If I withdraw $20,000 to take care of bills and home repair, how much should I request from my TSP account to cover the taxes and penalties?
A. Your withdrawal will be subject to 20 percent minimum mandatory federal tax withholding, so to receive $20,000 from the TSP, you’ll need to request $25,000. The actual federal income tax, early withdrawal penalty and state tax you’ll owe for the withdrawal won’t be computed until you file your tax return for the year of the withdrawal.
