Q: I’m 66 and employed by the Army. I am covered by CSRS-Offset and have been making contributions to the TSP, but no “make-up” contributions. I have applied for and received Social Security benefits based on full eligibility during this calendar year. Are my TSP contributions still excluded from my computation of Adjusted Gross Income?
A: Your TSP contributions via payroll deferral are always taken pre-tax and stay that way until you withdraw the money.
