Q: I am an employee (Federal Employees Retirement System) at a BRAC-ed installation. Sometime around September 2011, I will be fired. At 56 years old — the age at which I’ll have 29 years’ service — I can retire. I would like to cash in my Thrift Savings Plan (approximately $156,000), collect on my rolled-over leave ($54,000), collect on 50 percent of my sick leave ($17,000), collect my $25,000 and pay off all my debt. I’ll live on my pension and offset. Can I take out all my TSP funds, and what is the tax bite if I should do…
