31 C.F.R. §§ 29.523–29.525

Recovery is against equity and good conscience when there is substantial evidence that—

Financial hardship may be deemed to exist when the debtor needs substantially all of his or her current and anticipated income and liquid assets to meet current and anticipated ordinary and necessary living expenses during the projected period of collection. Financial hardship will not be found to exist when the debtor merely establishes that the repayment causes a financial burden, i.e., when it is inconvenient to repay the debt. If there are anticipated changes in income or expenses that would allow for the recovery of the overpayment at a later date, the Department may suspend collection action until a future date.

An individual's ordinary and necessary living expenses include rent, mortgage payments, utilities, maintenance, transportation, food, clothing, insurance (life, health, and accident), taxes, installment payments for which the individual is already liable, medical expenses, support expenses for which the individual is legally responsible, and other miscellaneous expenses that the individual can establish as being ordinary and necessary.
