Few things are more unsettling than opening a letter from the Social Security Administration (SSA) demanding that you repay thousands of dollars in benefits. For retirees who depend on those monthly checks, the notice can feel sudden and deeply disruptive.
But Social Security overpayments happen more often than most people realize. Understanding why they occur can help you avoid money mistakes and reduce the risk of repayment later.
Here’s what a Social Security overpayment means and why it can occur even if you thought everything was handled correctly.

What is a Social Security overpayment?
A Social Security overpayment occurs when you receive more than you were eligible to receive under program rules. The extra amount may result from earnings limits, benefit timing, or other eligibility factors.
When the SSA identifies the issue, it sends a notice explaining the reason, the amount owed, and your deadline to respond. The letter outlines your options, including appeal rights and repayment choices.
Although the notice can feel abrupt, it typically follows a routine review of earnings or benefit records. To understand why that review happens, it helps to look at the situations that commonly lead to overpayments.

Going back to work can unexpectedly shrink your check
If you claim benefits before full retirement age (FRA) and keep working, your earnings can reduce your monthly payment.
In 2026, the annual limit is $24,480 for those below full retirement age, and the Social Security Administration withholds $1 for every $2 earned above that amount. In the year you reach FRA, the limit for the months before your birthday is $65,160, with $1 withheld for every $3 earned above it.
The adjustment does not always happen immediately. You may receive full payments during the year, then see a correction after your actual earnings are reviewed.
Underestimating earnings can lead to a clawback
When you apply for benefits, Social Security asks how much you expect to earn during the year. That estimate affects how much the agency pays you. If your actual earnings end up higher than expected, your benefits may have been too high.
A raise, extra hours, or a return to work can push income over the level you originally reported. When the agency reviews your actual wages later, it adjusts the benefit, and any excess payments must be repaid.
Divorce, remarriage, or widowhood and shifting benefit rules
Social Security benefits can shift after major life events, especially when payments are based on someone else’s work record.

Common situations include:
-
Switching from spousal benefits to your own retirement benefit
-
Divorce or remarriage changing spousal eligibility
-
A dependent child reaching the age when payments must stop
If these changes aren’t reported quickly, Social Security may continue paying the old amount. Later, when the agency updates your record, it recalculates what should have been paid. If they overpaid during that transition, you’d owe money.
Mid-year retirement can complicate the calculation
Retiring partway through the year can create similar confusion. You may have earned most of your income before benefits began, yet the annual limit still applies.
There is a special monthly earnings rule designed to prevent obvious overpayments in these situations, but it’s easy to misunderstand. Higher earnings earlier in the year, or an incorrect estimate when applying, can still lead to a mismatch that Social Security corrects later.
Clerical mistakes that later require correction
Sometimes the error is on SSA’s side. Processing mistakes, incorrect earnings data, or delays in stopping payments can all lead to benefits that were higher than they should have been.
Reviews have documented thousands of such cases each year. For instance, a 2022 Inspector General report identified about 73,000 overpayments tied to benefit calculation accuracy issues. Congressional reports have also noted that total overpayments in recent years have ranged from $6 billion to $11 billion annually.
Even when the mistake wasn’t yours, the agency is still required to recover the excess. That’s why overpayment notices sometimes arrive even when your information was accurate and up to date.

What to do if you get a repayment notice
If you receive a repayment notice from the SSA, start by reviewing the explanation carefully. If you believe the calculation is wrong or that you were not overpaid, you have 60 days from the date on the notice to file an appeal, also called a request for reconsideration.
When the amount appears accurate but repayment would create financial strain, a waiver may be an option.
There is no deadline to request one, though you must show that you were not at fault and cannot afford to repay the balance. For overpayments under $1,000, the agency notes that a phone request may be sufficient.
You can also set up a repayment plan. Social Security typically withholds 10% of your monthly benefit, though you may request a lower rate if needed.
If you do not respond within 30 days, withholding can begin automatically. In some recent cases, that has meant up to 100% of a monthly check. Responding early gives you more flexibility in how the issue is resolved.
Bottom line
A repayment notice from the SSA can be unsettling, but it’s usually a problem in the paperwork, not a personal failing. Take the time to read the letter, understand the reason, and respond within the stated deadlines.
Staying current with income reports and updating the agency about major life changes can prevent similar issues later. That steady attention can help keep your benefits on track and support the kind of stress-free retirement most people aim for.
