A child had been collecting Supplemental Security Income since 1994 when his father qualified for Social Security retirement benefits in January 2006 — but the father’s application never named the child, and nobody flagged that the boy might also be owed a check on his father’s record. Four months later, in May 2006, the Social Security Administration ran a routine benefit redetermination on the child’s SSI case, one that should have doubled as the starting point for his claim on his father’s record. It didn’t. By the time an application was finally filed and SSA began paying him in October 2007, the family had lost $10,276 in benefits it should have received starting more than a year and a half earlier. A new inspector general audit found the case was far from unique.
The Redetermination That Should Have Been the Filing Date
When a parent starts collecting Social Security and a child later becomes eligible on that record, the date that matters most is not necessarily when someone finally fills out a form — it can be the date SSA was first told, even informally, that the child might qualify. SSI recipients are required to apply for every other benefit they might be eligible for, and periodic SSI eligibility reviews, called redeterminations, can turn up exactly that kind of overlooked eligibility. Under the Social Security Administration’s own rules, described in a new audit from the agency’s Office of the Inspector General, the earliest redetermination that surfaces a child’s eligibility for benefits on a parent’s record is supposed to serve as that child’s protective filing date. SSA ran that exact redetermination for the boy in May 2006. Employees never used it that way. An application for his benefits was not filed until later, and SSA did not start paying him until October 2007. Because the filing date was never corrected, the agency underpaid the child $10,276 covering January 2006 through September 2007.
The decision behind the number: Claiming at 62, at full retirement age or at 70 changes the monthly benefit permanently, and the break-even sits in a different place for every household. Compare the claiming ages in The Social Security Claiming & Family Benefits Kit.
Six Months on One Record, Twelve on Another
The rules governing how far back a child’s benefits can reach are specific, and they vary by whose record the child is claiming against. A child may receive retroactive benefits for up to six months before the application filing date on a retired or deceased parent’s record, or up to twelve months before the filing date on a disabled parent’s record. The filing date itself is not always the date SSA physically receives a signed application — it can instead be a protective filing date, marking when SSA was first told, even informally, that someone intended to file. That protective filing date generally stays valid for six months, after which it expires and the retroactivity clock resets to whatever date SSA actually receives the paperwork. There is one exception: if SSA fails to send the notice explaining the six-month deadline, the protective filing date does not expire and stays open indefinitely, no matter how long a family waits to file.
46 of 150 Cases Wrong, Projected to 195,260 Children Nationwide
The child’s case was one of 150 the inspector general’s office pulled at random from a single slice of Social Security’s master beneficiary file — one of 20 equal segments the agency uses to track every current and former retirement, survivor and disability beneficiary. From that one segment, auditors identified 31,836 children who might have been owed retroactive benefits, whose entitlement began after January 2005 and whose cases were still open as of May 2024. Reviewing the 150-case sample, auditors found SSA had properly paid retroactive benefits to 104 children, 69 percent, and improperly paid the other 46, or 31 percent. Because each of the 20 segments of Social Security’s beneficiary file is built to represent the whole population, auditors projected the sample’s error rate across all 20 and estimated 636,720 children nationwide fit the same criteria, with roughly 195,260 of them under- or overpaid because of the same kinds of filing-date and entitlement-date mistakes found in the sample.
$760.4 Million in Under- and Overpaid Retroactive Benefits
Auditors put a dollar figure on that projection: about $760.4 million in retroactive child’s benefits either shorted or overpaid nationwide, based on the $263,297 in improper payments they found across the 46 sample cases. Most of that money represents underpayments — cash owed to families that SSA never sent — though a handful of cases ran the other way, with SSA overpaying a family and then generally requiring it to repay the money. The audit notes that when a child is underpaid, the family’s finances take the hit directly; when a child is overpaid, the family faces a future repayment demand it may not be able to absorb, on top of the administrative cost SSA incurs trying to collect it. In a handful of cases, the wrong entitlement date also delayed a child’s Medicare eligibility, which the report says can leave a family covering medical bills Medicare should have paid.
Wrong Filing Dates, Wrong Entitlement Dates, Wrong Family Maximums
The 46 error cases broke down into three distinct kinds of mistakes, sometimes overlapping in the same file. SSA employees used the wrong protective filing date for 29 beneficiaries — the same category of error behind the $10,276 case — which led to $197,813 in underpayments across 22 children and a $5,614 overpayment in one more. Separately, employees calculated the wrong date a child actually became entitled to benefits in 43 cases, underpaying 17 of them a combined $44,995; the remaining cases in that category caused no immediate improper payment only because the family was already receiving the maximum benefit its record allowed. A third category involved the family maximum itself, the cap on how much a single earnings record can pay every eligible family member at once, which SSA miscalculated for six children, improperly paying them $14,875 combined. Investigators could not determine why employees made any of the errors; there was no explanatory note in SSA’s own case files.
What SSA Agreed to Fix
The inspector general recommended SSA correct the records and pay any retroactive benefits owed to the 78 beneficiaries identified across both rounds of sampling, and separately identify what is driving the broader pattern of employee errors so the agency can fix the underlying process rather than each case one at a time. SSA agreed with both recommendations, according to the June 24, 2026 report, though the agency’s written response, filed as an appendix, did not explain why its own employees have been unable to identify the cause of the errors themselves. Until that changes, the report’s own numbers suggest the family behind the $10,276 case has plenty of company: an estimated 195,260 other children whose retroactive benefits may still be resting on the wrong filing date, the wrong entitlement date, or a family-maximum calculation nobody rechecked.
The Six-Month Clock Nobody Marks on a Calendar
A protective filing date starts running the moment a family tells Social Security, even informally, that a child might be eligible on a parent’s record — but nothing in that conversation hands the family a calendar showing when the six-month window closes or what happens if a caseworker never uses it.
