Staff members defer federal and state income taxes on contributions to TIAA or an approved substitute annuity or supplemental annuity. An individual eligible for TIAA takes a salary reduction in an amount equal to the staff member's contribution to the retirement fund. That amount, plus the University's contribution is paid by the University in the staff member's name into the retirement fund; an income tax on the total annual contribution is postponed until the time benefits from the plan are received. Internal Revenue Service regulations have maximum contribution limits under this program. Contact the University Benefits Office for further information.
