In October 1992, a wage earner died at age 32, leaving behind a wife who would not apply for survivor benefits for another 24 years. When she finally filed in December 2016, the Social Security employee handling her claim used 1992 — the year her husband died — to calculate her benefit, instead of 2009, the year she first became eligible to claim as a widow. The difference dropped her monthly payment to $1,856 when Social Security’s own rules said she was owed $2,170, a shortfall of $314 every month that ran for more than eight years before anyone caught it. A new inspector general audit found she was one of dozens of widows and widowers shortchanged by the same kind of error.
One Wrong Year, $35,247 Lost
By the time investigators reviewed her file in January 2025, the widow had been underpaid $35,247 since December 2016, according to the audit the Social Security Administration’s Office of the Inspector General released in March 2026. If SSA does not correct the error, auditors estimated she stands to lose roughly $99,000 more over the remainder of her expected lifetime. The mistake traces to a Social Security calculation called the widow(er)’s indexing Primary Insurance Amount, or WINDEX, which applies when a wage earner dies before turning 62. Rather than using the year of death to compute benefits, SSA is supposed to use the year the widow or widower first became eligible to claim — in this case, 2009, when the widow turned 60. The employee who processed her 2016 claim used 1992 instead, and nothing in SSA’s system flagged the error.

A Calculation Manual Processing Gets Wrong
SSA’s Modernized Claims System can alert employees to some possible mistakes as they enter data, but auditors found it has no alert built specifically for WINDEX cases involving widows and widowers of wage earners who died before 62. A separate system, used for manually adjusting awards, does prompt employees to check for a WINDEX PIA in one narrow circumstance — when a surviving spouse with the deceased worker’s child in their care converts to widow’s benefits — but not in the broader set of cases like this one. Auditors said subject-matter experts could not explain why the employee who processed the widow’s 1992-dated claim made the error in the first place; there was no note in SSA’s system indicating what went wrong.
49 of 120 Widow(er)s Got the Wrong Amount
The widow’s case was one of 120 the inspector general’s office sampled from two populations of widow(er) beneficiaries the Master Beneficiary Record flagged as potentially eligible for higher payments. Overall, SSA paid the correct amount to 71 of the 120 beneficiaries reviewed — 59 percent — but got it wrong for the other 49, or 41 percent. Eleven of those errors, including the widow’s, came from a 70-person sample of beneficiaries without a WINDEX PIA on file; auditors found SSA had underpaid those 11 people a combined $97,768. A twelfth case went the other direction — SSA overpaid one widow(er) about $9,000 by using the wrong Primary Insurance Amount, a case investigators referred back to the agency for correction.
What SSA Owes the Wider Population
Projecting the sample results across the full population of 54,843 widow(er)s without a WINDEX PIA on record, auditors estimated SSA has underpaid 8,618 widow(er)s a combined $50.4 million, and stands to underpay 5,484 of them roughly $221.4 million more over their remaining lifetimes if it does not fix their records. SSA agreed to all four of the audit’s recommendations, including taking corrective action on the specific errors identified, evaluating the remaining population of 54,773 widow(er)s the sample did not cover, and building system alerts to catch WINDEX mistakes before they happen.
A Second Population, Underpaid for a Different Reason
The widow’s case belonged to one of two groups the audit examined. The second group — 50 beneficiaries sampled from 7,253 widow(er)s who were paid both survivor and retirement benefits starting the same month — turned up a separate problem: SSA could not show it had told 37 of them they had the option to collect widow’s benefits only and delay their retirement claim to grow it later. Thirty of those 37 were already past age 70 by the time of the review, and the sample showed they had lost out on $748,272 combined by not delaying; projected across the population, auditors estimated 4,347 beneficiaries over 70 missed roughly $108.5 million in benefits they could have claimed, and stand to collect about $169.8 million less over their remaining lifetimes as a result. The seven beneficiaries under 70 in the sample face a similar gap once they reach that age, projected at $5.2 million a year in lost benefits across an estimated 1,020 affected widow(er)s.
Cases SSA Won’t Reopen
Unlike the WINDEX errors, this second set of cases will not get corrected. Auditors could not determine whether SSA employees had actually discussed the tradeoff with the 37 widow(er)s, because the conversation was never logged in the agency’s claims system, and SSA’s Office of Law and Policy ruled that the absence of a written record does not prove the discussion never happened. It classified the claims as final under the agency’s administrative finality rules and declined to reopen them, even though SSA made an identical recommendation, and issued the same reminder to employees, after two nearly identical audits in 2016 and 2018 found the same pattern.
The Calculator Widow(er)s Rarely See Before They File
Nothing in a Social Security award letter flags whether a widow’s eligibility year was calculated using the year a spouse died or the year survivor benefits actually began. That choice, and the decision about when to claim which benefit, is made once, at a field office, based on whatever the application form covers unless it is deliberately narrowed.
