The Social Security statement you received last month probably looks straightforward. A monthly number, a payment date, a few lines of fine print. But for a significant slice of Americans currently receiving benefits, that number is wrong – either lower than it should be, or about to get a chunk taken back for reasons they didn’t cause and may not fully understand.
The people most likely to be affected aren’t gaming the system. They’re teachers who spent 25 years in a state pension and a few years in private-sector work. They’re retirees who picked up part-time work after claiming benefits, not realizing the earnings rules would claw money back. They’re widows and widowers who didn’t know they could claim survivor benefits until someone mentioned it in passing.
Here’s a breakdown of the scenarios most likely to leave seniors with less money than they’re owed – or facing an unexpected repayment demand.
1. The Social Security Glitch Seniors Didn’t Cause: WEP and GPO Underpayments
For decades, two provisions buried inside the Social Security rulebook reduced benefits for millions of public servants. The Windfall Elimination Provision (WEP) cut retirement benefits for workers who also received a pension from a job that didn’t pay into Social Security – think state teachers, police officers, and federal employees under the old Civil Service Retirement System. The Government Pension Offset (GPO) went further, slashing or wiping out spousal and survivor benefits for the same group.
The Social Security Fairness Act, signed into law in January 2025, ended both the WEP and the GPO. These provisions had reduced or eliminated Social Security benefits for millions of people who received a pension based on work not covered by Social Security. For many of them, the reduction had been running for years, silently carving away at a benefit they had legitimately earned.
As of July 7, 2025, the SSA completed sending over 3.1 million payments totaling $17 billion to beneficiaries eligible under the Act, five months ahead of schedule. Depending on the type of Social Security benefit received and the amount of a person’s pension, some people’s benefits will increase very little while others may be eligible for over $1,000 more each month.
Unlike WEP adjustments, GPO corrections were not always automatic – potentially affected retirees often had to apply to receive spousal or survivor benefits. If you’re a surviving spouse of a public-sector worker and you never received Social Security survivor benefits because the GPO would have zeroed them out, that benefit may now be available to you. Not claiming it doesn’t mean you weren’t entitled to it. It means no one told you the rules had changed.
2. You Received an Overpayment Notice for a Mistake You Didn’t Make
AARP reports that many overpayments are not the fault of beneficiaries but rather miscalculations on the part of the Social Security Administration due to untimely beneficiary updates. The agency’s own systems can lag months or even years behind real-life changes – a marriage, a part-time job, a shift from disability to retirement benefits. These letters often arrive long after the alleged error, leaving retirees confused and panicked.
A 2024 report from the SSA’s Office of the Inspector General found the SSA made approximately $71.8 billion in “improper” payments, most of them overpayments, in federal fiscal years 2015 through 2022. That sounds abstract until the letter arrives. Then it isn’t abstract at all.
What makes this especially sharp-edged right now is the current withholding policy. The policy trajectory has been chaotic: the Biden administration capped clawbacks at 10% in March 2024 after public outcry, the Trump administration reinstated 100% withholding starting March 27, 2025, and then the SSA walked that back to 50% on April 25, 2025. “Oftentimes, these mistakes are actually Social Security’s fault – and slapping people with huge penalties for mistakes other people made just isn’t right,” said Bill Sweeney, AARP’s senior vice president for government affairs. Jack Smalligan, a senior policy fellow at the Urban Institute, adds that overpayments often result from people “misunderstanding the rules and not intentionally violating the rules.”
For overpayment notices issued after April 25, 2025, the SSA will withhold up to 50% of your monthly benefit if you do not request a waiver, reconsideration, or rate reduction within 90 days. You can avoid this by responding to the notice and requesting a lower rate or a full waiver. If you can’t afford to repay and the error wasn’t your fault, a waiver request is the right move. Ignoring the letter is the one thing guaranteed to make it worse.
3. You’re Working Before Full Retirement Age and Don’t Know the Earnings Rules
According to CNBC, the Social Security retirement earnings test may reduce benefits for certain individuals who are under full retirement age and who continue to work. The rules are genuinely counterintuitive. You can claim Social Security at 62, keep working, and find that a chunk of every check gets withheld – not as a penalty exactly, but as a deferral that most people experience as a loss.
If you are under full retirement age for the entire year, the SSA deducts $1 from your benefit payments for every $2 you earn above the annual limit. For 2026, that limit is $24,480. In the year you reach full retirement age, the SSA deducts $1 in benefits for every $3 you earn above a different threshold – in 2026, that’s $65,160. Part-time work, freelance income, and consulting fees all count. A pension doesn’t count, but a side job absolutely does.
Beneficiaries affected by the retirement earnings test will have their benefits recalculated once they reach full retirement age to credit for the months their benefits were reduced or withheld. So the money withheld this way isn’t gone forever – but if your life expectancy is shorter than average, you may not recoup all of those held-back benefits. Knowing the threshold before claiming, not after, is the only way to make a genuinely informed decision.
4. You’re Being Underpaid Because Your Earnings Record Has an Error
Your Social Security benefit is calculated from your 35 highest-earning years. If any of those years are recorded incorrectly – a missing W-2, a clerical error at an old employer, wages that never got properly reported – your baseline benefit is wrong, and it’s been wrong since the day you claimed.
Workers need to keep an eye on accumulating enough Social Security credits and correct errors in their earnings record. The SSA sends annual statements showing earnings year by year, and the window for correcting old errors isn’t unlimited. Documentation – old pay stubs, employer records – may no longer exist, making errors from many years ago harder to fix.
Create or log into your account at my Social Security and pull up your full earnings history. Go through it year by year, especially the years when you earned the most. If a year looks wrong – a zero where there should be income, or a number that seems too low – that’s worth pursuing. The SSA can sometimes correct records using IRS wage data, but you have to initiate the request. Nobody else will do it for you.
5. Your Medicare Premiums Are Being Miscalculated Under IRMAA
Most people know that Medicare Part B premiums are automatically deducted from Social Security checks. Fewer know that those premiums can jump significantly if your income crosses certain thresholds – a surcharge called IRMAA (Income-Related Monthly Adjustment Amount). And fewer still know that IRMAA is based on tax returns from two years prior, which means a one-time income event – selling a house, taking a large IRA distribution, receiving a lump-sum pension payout – can trigger a higher premium even if your current income is much lower.
According to Kiplinger, the Medicare surcharge in 2026 applies to beneficiaries with modified adjusted gross income exceeding $109,000 for single filers or $218,000 for joint filers. Around 8% of Part B beneficiaries pay these higher monthly premiums, according to the Centers for Medicare & Medicaid Services. The Part B deductible also rose to $283 in 2026, up from $257 the year before.
The surcharge is applied automatically, without any individual review of whether the triggering income event was a one-time anomaly. You can appeal an IRMAA determination using what’s called a “life-changing event” – retirement, divorce, the death of a spouse, or a significant reduction in income. The form is SSA-44. If your income in the prior year dropped substantially compared to the year used to calculate your premium, filing that appeal can meaningfully increase what lands in your account each month.
6. You Were Overpaid Because You Hit the Earnings Limit Without Realizing It
Some seniors who are under full retirement age and still working aren’t certain whether they’ll exceed the annual earnings limit. Under Social Security rules, the agency holds back $1 in benefits for every $2 in earnings above the threshold, and some seniors let things ride because they won’t know until late in the year whether they’ve gone over.
Under the current clawback policy, that gamble can cost more than people expect. Seniors who end up over the limit could lose one or two months of benefits due to the clawback policy. If you’re collecting Social Security while still working and unsure whether your earnings will exceed the limit, the more cautious move is to notify the SSA proactively and ask them to adjust your payments mid-year. It’s an extra phone call, but considerably less painful than receiving a repayment demand in January.
If you are working or planning to work while receiving benefits, the SSA usually asks you to estimate your earnings for the year. If you do not report your estimated earnings and get paid too much, you may have to repay those benefits. Reporting a conservative estimate – and updating it if you earn more – keeps you in control of the situation rather than reacting to it after the fact.
7. You Haven’t Claimed a Spousal or Survivor Benefit You’re Entitled To
This is possibly the most underreported category of lost Social Security money. Spousal and survivor benefits are not automatic – you have to apply for them. And for years, many spouses of public-sector workers never bothered applying because the GPO would have wiped the benefit out anyway. With the GPO now gone, that calculus has changed.
Those already receiving their own Social Security benefit can submit a spousal or survivor benefit application now that GPO has been removed. If they are older than full retirement age, they can backdate that application by up to six months – but those younger than full retirement age cannot backdate their application. That six-month window matters. If you wait too long, you lose those months permanently.
The ongoing issue specifically relates to those who never applied for Social Security benefits while the GPO was in effect because it would have eliminated them entirely. These are people who wrote off an entire benefit category and stopped thinking about it. If that describes your situation – you’re the surviving spouse or current spouse of someone who worked in a non-covered government job – it’s worth calling the SSA and asking specifically about your eligibility. When you call 1-800-772-1213, saying “Fairness Act” routes you to a representative trained on WEP and GPO cases.

What This Actually Means
The system isn’t designed to catch its own mistakes on your behalf. The SSA contacts over one million Americans annually to recoup funds it disbursed in error – and although overpayments can take months or years to be recognized by the agency, once one is identified, the impact to beneficiaries is nearly instantaneous. The inverse is equally true: underpayments and missed benefits can run for years without triggering any notification at all.
The through-line across all seven scenarios is the same. The SSA processes a staggering volume of payments using a system that relies heavily on self-reporting, older technology, and manual case handling for anything complex. With field offices stretched thin and call answer rates well below what they should be, waiting for the agency to find an error is not a reliable strategy.
Checking your my Social Security account annually, reporting any change in income or living situation promptly, and responding immediately to any overpayment notice rather than ignoring it – these aren’t just good practices, they’re the practical difference between getting what you’re owed and quietly getting less. Most of the money left on the table isn’t the result of a complicated fraud or a dramatic bureaucratic failure. It’s the result of a form no one filed, a call no one made, or a letter that sat on the kitchen counter unopened for too long. Some of these problems go back years before anyone noticed. Naming that isn’t a solution, but it’s where the real conversation starts.
