Social Security Can Withhold Half Your Benefit Over an Overpayment: A CPA Says Do This Before You Pay Anything

The agency says it has recovered $645 million in old debts. On an average benefit, half comes to $1,047 a month.

The Social Security Administration says it has a number to tout: $645 million.

In a recent update on its fiscal year 2026 outlook, the agency said that after restarting the Treasury Offset Program — which can seize federal payments such as tax refunds — it had “recovered approximately $645 million in delinquent programmatic debts since resuming collections.” In simple terms, Social Security says that is money people owed the agency.

For benefit recipients, one common way to end up owing Social Security is through an overpayment. The agency defines that situation plainly: “you receive more money than you should have from us.”

And if you do not respond to an overpayment notice, the default is now much harsher: Social Security withholds 50% of your monthly benefit, up from 10%. SSI recipients face a 10% withholding rate.

I’ve been a CPA since 1981, and my advice is simple if an overpayment notice shows up in your mailbox: do not pay it blindly. Before you send a dime, take these five steps. The clock starts on the date of the notice.

1. Understand the risk: Half your check

If you do not repay within 30 days of the notice date, Social Security says it will “withhold 50% of your benefit.”

That is a serious hit. Social Security estimates the average retired worker’s monthly benefit at $2,094 before the next cost-of-living increase. Half of that is $1,047 — gone each month until the debt is cleared.

Very few retirees can afford to lose half their check without rearranging their budgets. If you suddenly come up short, start by reviewing the bills that run automatically.

Subscriptions you forgot about, free trials that never ended and yearly fee increases are some of the easiest leaks to miss. One service can connect to your accounts and show every subscription in one place so you can cancel the ones you do not want in just a few taps.

It can also negotiate cable, internet and phone bills and flag fee hikes before they take effect. Members have saved more than $880 million through canceled subscriptions so far.

Ten minutes could help stop the leak for good.

2. Move within 30 days to pause collection

This is the most important deadline in the letter.

According to Social Security, if you ask for a waiver or file an appeal within 30 days, the agency will not collect the money until it decides on your request.

If you miss that window, withholding can begin while you are still disputing the claim. Do not let the letter sit unread. Open it, read it carefully and note the date.

3. If the numbers look wrong, appeal

Errors happen. If you believe you were not overpaid, or that the amount listed is incorrect, you can challenge it.

The agency says an appeal should only be filed if you disagree with the overpayment amount. In general, you have 60 days from the date you received the notice to file.

Ask the agency how it calculated the amount you supposedly owe, then compare that figure with your own records, including bank deposits, earnings statements and any letters about changes to your benefit.

4. If it was not your fault, ask for forgiveness

Even if the overpayment is real, repayment may not be required.

Social Security’s waiver form, SSA-632, asks you to show that the overpayment was not your fault and that you cannot afford to repay it, or that repayment would be unfair for another reason.

The agency’s guidance says the same thing in other words: the overpayment was not your fault, and paying it back would create financial hardship or would be unfair.

Waivers are not automatic, so answer every question on the form carefully.

If the overpayment stems from a decision you made about your benefits, it may also be a sign that your broader Social Security strategy needs attention.

For people with at least $100,000 invested, a free matching service can connect them with up to three fiduciary financial advisors who are legally required to put clients’ interests first.

Those advisors can help with taxes, investing, Social Security strategy and planning gaps you might miss on your own. The first appointment is typically free.

The questionnaire takes about 10 minutes and asks for a phone number near the end, but you control whether and when you respond. The service provides the match, not the advice, and a referral fee may be earned.

5. If you do owe it, ask for a smaller repayment

Sometimes the overpayment is legitimate and a waiver is not available. Even then, you do not necessarily have to accept a 50% cut.

The SSA-632 is officially titled “Request For Waiver Of Overpayment Recovery Or Change In Repayment Rate.” If Social Security cannot waive the debt, the form says it may use your answers to decide how you should repay it.

In other words, the same form can also be used to request smaller monthly payments. Fill it out honestly and completely.

My bottom line

No one likes owing money, and if you truly were overpaid, you should repay it. That is fair.

But the burden should not fall entirely on you. Agencies make mistakes, and the default response can be to take half of your check if you do nothing.

So treat an overpayment letter like a tax notice: do not panic, do not ignore it and do not simply pay it. Check the math, watch the 30-day deadline and make Social Security prove its case.
