20 C.F.R. § 416.553
We will waive adjustment or recovery of an overpayment when an individual on whose behalf waiver is being considered is without fault (as defined in § 416.552) and adjustment or recovery of the overpayment would defeat the purpose of the supplemental security income program.
(b) Alternative criteria for individuals currently eligible for SSI benefits. We consider an individual or couple currently eligible for SSI benefits to have met the test in paragraph (a) of this section if the individual's or couple's current monthly income (that is, the income upon which the individual's or couple's eligibility for the current month is determined) does not exceed—
(4) The applicable State supplementary payment, if any (see subpart T of this part) for the month in which determination of waiver is made.
For those SSI recipients whose income exceeds these criteria, we follow the general rule in paragraph (a) of this section.
