The Social Security “Clawback”: 5 Mistakes That Could Shrink Your 2026 Monthly Check

Your Social Security check might seem like one stable thing you can count on each month. The money arrives on schedule, the amount feels predictable, and you’ve probably built your budget around it. Then one day, you notice something’s off. The deposit is smaller than usual, or maybe it doesn’t come at all. Welcome to the world of Social Security mistakes that can quietly drain your benefits without warning.

Let’s be real, nobody wakes up thinking they’re about to accidentally forfeit hundreds or even thousands of dollars in Social Security payments. Yet it happens to nearly a million Americans every year. Some lose half their monthly check for months on end. Others face sudden 100 percent withholding that leaves them scrambling to cover rent or prescriptions. The scary part? Many of these situations stem from simple reporting errors, misunderstood rules, or outdated information sitting in a government file somewhere. Here are five critical mistakes that could shrink your 2026 check before you even realize what’s happening.

Failing to Report Changes That Trigger Overpayments

Incorrect or incomplete information from self-reporting is a leading cause of payment errors, though some mistakes do originate from the agency itself. Here’s the thing: Social Security expects you to report changes in income, marital status, living arrangements, and work activity promptly. When you don’t, the system keeps paying you based on outdated data. Months or even years later, the agency discovers the discrepancy and suddenly you’re hit with a notice saying you owe thousands in overpayment.

Between fiscal years 2015-2022, the Social Security Administration estimates that it made nearly $72 billion in overpayments, though this represents less than 1% of total benefits paid out. Still, that’s real money affecting real people. Overpayments are rare and often the result of Social Security’s own miscalculations, making them a nasty surprise for beneficiaries who assumed the government had it right all along.

The fix is pretty straightforward but requires vigilance. If your income changes, your spouse passes away, or you move in with family, report it immediately. Don’t wait for the annual review. Overpayments can happen when a recipient doesn’t report changes in their income or living situation, but also due to administrative mistakes by SSA. The sooner you notify the agency, the less likely you’ll face a clawback down the road.

Earning Over the Limit While Collecting Early

In 2026, if you’re under full retirement age, the annual earnings limit is $24,480, but if you will reach full retirement age in 2026, the limit on your earnings for the months before full retirement age is $65,160. Cross these thresholds and Social Security starts withholding benefits fast. The Social Security Administration temporarily withholds $1 of a worker’s benefits for every $2 earned above $24,480 in 2026 if you’re under full retirement age all year.

Think you can fly under the radar with a part-time job? Think again. When figuring out how much to deduct, Social Security counts only wages from your job or net profit if you’re self-employed, including bonuses, commissions, and vacation pay. They don’t count pensions or investment income, but work earnings are fair game.

If you claim benefits before your Full Retirement Age and continue to work, you face the Retirement Earnings Test, and in 2026, the exempt earnings limit has risen to $24,480, though this adjustment disproportionately hurts those with irregular or seasonal income. One busy month could push you over the edge. Some seniors decide to “let it ride” because they won’t know until late in the year if they’ll exceed the limit, but those opting for a strategic overpayment could end up losing one or two months of benefits due to the clawback policy.

Ignoring the New Overpayment Recovery Rules

The overpayment recovery landscape shifted dramatically in 2025, and if you’re not paying attention, you could lose your entire check. The Social Security Administration announced it will increase the default overpayment withholding rate for Social Security beneficiaries to 100 percent of a person’s monthly benefit, with the Office of the Chief Actuary estimating this change will result in program savings of about $7 billion in the next decade. People who are overpaid after March 27 will automatically be placed in full recovery at a rate of 100 percent of the Social Security payment.

However, there’s been some back-and-forth on this. The SSA announced in April that it would begin withholding 50 percent of benefit payments from recipients who have been overpaid, representing a significant increase from the previous 10 percent withholding rate, affecting approximately 2 million Americans. The Social Security Administration will withhold up to half of benefits instead of 100 percent from those who owe for past payment errors.

More than 7 million Americans 65 and older receive at least 90 percent of their income from Social Security, and the impact of missing even one or two monthly payments can be catastrophic. If someone cannot afford full recovery, they can contact Social Security at 1-800-772-1213 or their local office to request a lower rate of recovery, and they can ask Social Security to waive collection if they believe it was not their fault and can’t afford to pay it back. Don’t just accept the default withholding rate. Appeal it, request a waiver, or negotiate a payment plan. The system allows for flexibility if you push back.

Missing Medicare Premium Increases That Eat Your COLA

You got a 2.8 percent cost-of-living adjustment for 2026, right? Sounds good until you realize Medicare premiums also increased. The official 2026 COLA is 2.8%, but because Medicare Part B premiums rose by a flat dollar amount, the real raise depends entirely on the size of your check, with high-income earners receiving the maximum benefit keeping plenty of extra cash while low-income retirees receiving just $1,200 see the premium hike consume more than half their new money.

Medicare coverage could be another pitfall for seniors whose benefit checks are subject to clawback, as most seniors pay for their Medicare Part B premiums by having it automatically deducted from their Social Security monthly checks. It’s unclear if seniors would have to arrange to pay for their Medicare premiums through another payment system, or if the SSA would allow them to pay for their health care first before clawing back the remaining money, potentially causing them to lose Medicare coverage.

Honestly, this is where things get messy. You might assume your COLA covers rising costs, but the math rarely works that way. The regressive structure means that those who need the COLA the most are actually keeping the smallest percentage of it. The solution? Know exactly what your net payment will be after Medicare and other deductions. Don’t budget based on the gross amount.

Not Checking Your Earnings Record for Errors

Your Social Security benefit is calculated based on your highest 35 years of earnings. If those records are wrong, you’re getting shortchanged every single month without knowing it. Employers sometimes misreport wages, names get misspelled, or earnings from years ago simply don’t appear in the system. The longer you wait to fix these errors, the harder they become to correct.

It’s important for beneficiaries to update the SSA with their latest information, such as increases in income, though the importance of updating the agency about such changes may not be fully appreciated by some because of the complexity of the Social Security system. It’s important to keep records of your payments and flag any issues, such as if your check is larger than it previously was, because unfortunately the onus is on you to correct the record.

I know it sounds crazy, but checking your earnings record annually should be as routine as reviewing your credit report. Log into your my Social Security account and scan every year listed. If something’s missing or incorrect, file a correction request immediately with supporting documentation like W-2s or pay stubs. The SSA won’t automatically catch these mistakes, and once you claim benefits, fixing them becomes exponentially more complicated.
