What do taxable and non-taxable dollars represent?
The taxable dollars in your account represent deposits you have paid into TRS since January 1988, as well as any service credit purchase you may have paid with a rollover of tax-deferred dollars from another retirement plan or IRA, plus all interest your account has earned from inception to date. The non-taxable dollars, if any, represent the deposits you paid into your TRS account prior to January 1988, as well as any service credit purchase you may have paid for with after-tax dollars.
