Social Security’s Office of the Inspector General estimates that the agency never paid about 610,165 back payments, worth $195,638,055 in total, that were owed to living Supplemental Security Income recipients. The watchdog’s audit of SSI underpayments, dated August 28, 2026, puts the wider gap at 1.1 million unpaid underpayments worth about $291 million once survivors are counted. Social Security told the auditors it agreed with all of their recommendations.
For people on SSI, the question is what they will get and when. An underpayment is a back payment owed because the agency paid too little in an earlier month. Social Security has not announced a payment date for the unpaid cases. The auditors recommended that the agency act on the 139 underpayments the audit identified and decide whether and how to find and resolve the rest. A recipient who believes a back payment never arrived can start with Social Security’s SSI page, and a file of income and resource records makes any later review easier.

How many SSI back payments went unpaid?
The inspector general counted 2,502,159 SSI underpayments pending in the agency’s records as of September 2024. Of those, 1,135,190 were owed to living recipients and 1,366,969 to recipients who had died. From a sample, the auditors project that Social Security did not pay about 610,165 of the living recipients’ underpayments, totaling $195,638,055.
Because the figures are projections, the audit gives ranges. For living recipients the estimate runs from 499,154 underpayments worth $99,775,640 up to 718,745 worth $291,500,470. For deceased recipients, the audit estimates 444,265 unpaid underpayments totaling $94,907,619, within a range of 326,322 ($23,228,128) to 575,932 ($166,587,111).
What did the 160-case sample show?
Auditors reviewed 160 underpayments, 80 for living recipients and 80 for deceased ones. In 69 of them, or 43 percent, Social Security employees “did not follow policy” to make sure the recipients were paid what they were due, the audit says. Those 69 underpayments came to $36,971. The remaining 91 sampled underpayments were not part of that finding.
That sample is the basis for the 610,165 figure. It is a statistical projection from the sample, not a list of named recipients, which is why the audit reports ranges and rounds the overall total to about $291 million.
How do large SSI back payments get paid?
The audit describes two rules that apply to big back payments. Since March 16, 2024, an SSI underpayment of $15,000 or more requires a pre-payment review; before that date the threshold was $5,000. And an underpayment equal to or larger than three times the maximum Federal Benefit Rate, the top monthly SSI amount, is paid in no more than three installments, each spaced six months apart.
What did Social Security agree to fix?
The audit makes three recommendations. Social Security should take action on the 139 underpayments the audit identified. It should determine whether and how to identify and resolve the estimated 1.1 million outstanding underpayments owed to SSI recipients or their eligible survivors. And it should identify the factors behind employee errors and put corrective actions in place so erroneous underpayments are found and removed from the Supplemental Security Record.
The memo comes from Assistant Inspector General for Audit Michelle L. Anderson, acting as First Assistant, and is addressed to Commissioner Frank Bisignano. Social Security agreed with all three recommendations. Agreeing is not paying: the agency has not announced how many of the 610,165 living recipients will be located or when back payments would go out, and the second recommendation asks it only to decide whether and how to resolve the rest.
Waiting on an SSI back payment?
An SSI back payment can sit unpaid when a case is handled wrong, and the audit found 43 percent of its sampled underpayments were not paid as required. A recipient who cannot show their income and resource history has less to point to when a payment, review or notice is questioned.
The SSI & Disability Action Kit lays out the 2026 SSI income and resource limits and the review and reporting steps, and its income and resource organizer gives a recipient one place to keep those records. The kit also includes the rules for working without losing benefits.
