Auditors project that 4,347 surviving spouses already past age 70 have missed a combined $108.5 million in Social Security benefits because a required recalculation never happened, according to a March 2026 report from the Social Security Administration’s Office of the Inspector General. The estimate covers widow and widower beneficiaries whose payments should have grown to reflect delayed retirement credits a deceased spouse earned by waiting to claim retirement benefits. Auditors built the projection from a review of records tied to a wider population of widow and widower beneficiaries still being examined.
A Projection Built From a Sample of Widow and Widower Files
The audit reviewed a population of 7,253 widow and widower beneficiaries whose records showed a deceased worker had delayed claiming retirement benefits, earning delayed retirement credits that should have raised the eventual survivor benefit. Auditors project that within that group, 4,347 beneficiaries already past age 70 have missed a combined $108.5 million in benefits because their survivor payment was never recalculated to reflect those credits.
A separate 1,020 beneficiaries under 70 carry an estimated $70 million in lifetime impact if the same recalculation gap continues as they age into their own 70s. Added together, the two groups inside the 7,253-beneficiary population account for most, though not all, of the delayed retirement credit cases the audit identified.
Inside the kit: a six-tab calculator comparing survivor benefits against a claiming-age recalculation, and a large-print quick start for walking through the comparison step by step. The Social Security Claiming & Family Benefits Kit puts both in one download.
How a Delayed Retirement Credit Is Supposed to Carry Over
When a worker delays claiming a retirement benefit past full retirement age, Social Security adds delayed retirement credits that raise the monthly amount up to age 70, a mechanism the agency explains on its own retirement planning pages. If that worker dies, current rules call for a surviving spouse’s benefit, which Social Security’s survivor benefits page describes as based on the deceased worker’s record, to be recalculated using those earned credits once the survivor reaches full retirement age or later.
The $108.5 million projection reflects cases where auditors found no evidence that recalculation occurred. The formula itself is not new or unusual; it is the same delayed retirement credit calculation Social Security applies to a worker’s own retirement claim, carried over to a survivor’s benefit once the worker has died. What changes in a survivor case is that the recalculation has to be triggered on a second person’s record, using the deceased worker’s history rather than the survivor’s own earnings, which is one more step where a file can stall.
A Second, Separate Group in the Same Review
The delayed retirement credit issue was not the only calculation problem the audit identified among widow and widower beneficiaries. A separate data-matching issue, which auditors label WINDEX, affected an estimated 8,618 beneficiaries, worth $50.4 million, with a projected lifetime effect of $221.4 million across 5,484 beneficiaries if left uncorrected. The two problems stem from different causes inside Social Security’s records, but both left survivors collecting less than the rules call for.
Keeping the two categories separate matters for reading the audit accurately. The $108.5 million figure in this report’s headline belongs only to the delayed-retirement-credit group of 4,347 beneficiaries over 70; it does not include the WINDEX population, whose dollar totals are tracked on their own. Combining the categories without noting the distinction would overstate what any single recalculation effort is actually expected to recover.
Why a Group Projection Reads Differently Than a Single Case
A projection like the $108.5 million figure describes a pattern auditors found repeated across a defined population, rather than a single file traced start to finish. That makes it useful for measuring the scale of a problem, roughly 4,347 beneficiaries sharing the same kind of unrecalculated benefit, without requiring auditors to publish every individual’s payment history. It also means the figure moves as a group: correcting one beneficiary’s file does not change the total for the other 4,346, since each recalculation happens on its own record.
The average shortfall implied by the group figure works out to roughly $25,000 per beneficiary across the 4,347 affected by the over-70 finding, though any individual case can run higher or lower depending on how long the unapplied credit went uncorrected and how large the credit itself was.
Most of the Population Still Waiting for Review
As of the audit, Social Security had a remaining population of 54,773 widow and widower beneficiaries it had not yet reviewed for either issue, a group considerably larger than the 7,253 already identified as affected by the delayed retirement credit problem. Social Security’s Office of the Inspector General recommended the agency complete that review and pay any amounts still owed, and the agency agreed to the recommendations.
Until the remaining files are checked, the $108.5 million figure represents only the beneficiaries auditors have confirmed so far, not a final count of everyone affected by the same calculation gap. Whether the eventual total lands higher or lower than today’s projection depends entirely on what that review of the remaining 54,773 files turns up.
A Projection That Still Depends on a File-By-File Review
A number this size is an estimate built from a sample, not a list of names, and the agency’s own review of the remaining files is not finished. A surviving spouse has no way to know from a monthly deposit alone whether a delayed retirement credit was ever applied correctly.
