Any amount due TRS because of earnings exceeding the maximum must be repaid by the member within 30 days of the billing date. TRS has the right to suspend monthly benefits once the member has reached their earnings limit and continues to be employed. TRS may also offset up to 25% of a member's monthly benefit payment to recoup overpayments. Repayment of benefits forfeited due to employment in excess of the maximum limit will require an interest penalty consistent with the actuarially assumed rate of return applicable to the billing, compounded monthly from the date due to the date of repayment.
