(a) When an overpayment has been made to an individual who is entitled to further payments, the individual shall refund to OWCP the amount of the overpayment as soon as the error is discovered or his or her attention is called to same. If no refund is made, OWCP shall decrease later payments of compensation, taking into account the probable extent of future payments, the rate of compensation, the financial circumstances of the individual, and any other relevant factors, so as to minimize any hardship. Should the individual die before collection has been completed, collection shall be made by decreasing later payments, if any, payable under the FECA with respect to the individual's death. If no further benefits are payable with respect to the individual's death, OWCP may also file a claim with the estate of the individual or seek repayment of the overpayment through other means including referral of the debt to the Treasury Department.

(b) When an overpayment has been made to an individual who is not entitled to further payments, the individual shall refund to OWCP the amount of the overpayment as soon as the error is discovered or his or her attention is called to same. The overpayment is subject to the provisions of the Federal Claims Collection Act of 1966 (as amended) and may be reported to the Internal Revenue Service as income. If the individual fails to make such refund, OWCP may recover the same through any available means, including offset of salary, annuity benefits, or other Federal payments, including tax refunds as authorized by the Tax Refund Offset Program, or referral of the debt to a collection agency or to the Department of Justice.
