An SSDI overpayment notice means SSA thinks it paid you money you weren't due, and since April 2025 its default is to take half of every check until it's repaid. You can challenge the amount, ask for the debt to be waived, or negotiate a smaller payment. Here's how each one works and how fast you need to move.
It's money SSA says it paid you that you weren't due. The notice will give a total, the months it covers and a reason. You have real options before a cent comes out of your check. What you can't do is ignore it. Silence is what triggers the harshest collection rate.
Since notices dated April 25, 2025, SSA's default for Social Security and SSDI overpayments is to withhold 50% of your monthly benefit until the debt's repaid. It was 10% for about a year before that, and 100% before that. SSI overpayments still default to 10%. Withholding usually starts about three months after the notice, which leaves at least 60 days to respond.
The reason on the notice decides which fix fits, so read it first. These are the common ones:
| Cause | What happened | What to look at |
|---|---|---|
| Work earnings not reported after the trial work period | Checks kept arriving for months your countable pay was over SGA ($1,690 a month in 2026) | Usually appeal the months, not the rule |
| Workers' comp or another public disability benefit started | SSDI should have been reduced by the offset and wasn't | Check SSA used the right award amount |
| Benefits continued during a medical review appeal | You chose to keep benefits while appealing, then lost | Waiver is possible if you appealed in good faith |
| A child's benefit paid after they turned 18 or left school | Dependent benefits should have stopped | Check the end date SSA used |
| SSA's own calculation or processing error | You were paid what SSA told you, then it changed its mind | Strongest waiver case: you weren't at fault |
| SSI only: savings over $2,000 ($3,000 for a couple), or a change in living arrangements | SSI is means-tested month by month | Separate rules; default recovery stays at 10% |
The first row is a classic for people who've gone back to work. Earnings that were reported late, or reported to the employer but not to SSA, leave SSA paying checks for months it later decides you weren't due. If you're working now, how the trial work period works explains which months count.
Take someone getting $1,630 a month who was paid for six months they shouldn't have been, a $9,780 overpayment. Here's how long it lasts under each route:
| Repayment route | Taken each month | How long it lasts |
|---|---|---|
| 50% default (SSDI notices since April 25, 2025) | $815 | 12 months |
| 10% (old SSDI default; still the SSI default) | $163 | 60 months |
| $100 a month, negotiated with Form SSA-634 | $100 | 98 months (8 years 2 months) |
| Pay it back in one go | $9,780 once | Immediately |
| Waiver approved (Form SSA-632) | $0 | Debt cancelled |
Half a check for a year is what happens if you don't respond. To see what your own monthly benefit is, and so what 50% of it would be, run it through the SSDI calculator.
They're different requests, and you can make both.
Either way, if you ask within 30 days of getting the notice, SSA won't start withholding while it decides. Ask later and it still stops collecting once it has your request, but money already withheld isn't automatically handed back.
You have to clear two tests. First, you weren't at fault: you didn't give SSA wrong information, you reported what you were supposed to, and you didn't have reason to know the payment was wrong. Second, repaying would either defeat the purpose of the program, meaning you need your income for ordinary living costs like rent, food and medicine, or be against equity and good conscience, meaning you relied on the money and gave something up because of it.
Fault is where most waivers are won or lost. Proof that you reported your work on time, such as an app confirmation, a fax receipt, a letter or the name of the person you spoke to, can be decisive. The SSA-632 also asks for a full budget, so add up income and expenses honestly. SSA can't deny a waiver without first offering you a personal conference to explain your side.
Ask for a lower rate. Form SSA-634 lets you propose a monthly amount based on your actual income and expenses, and SSA will often agree to a figure you can live with. It's the right move when the overpayment is valid and you were at fault, so a waiver isn't realistic. You can also repay in full or in a lump sum to end it.
If you're no longer on benefits, SSA can't withhold from a check, so it sends repayment requests instead. Unpaid debts can be sent to the Treasury Offset Program, which takes federal tax refunds and some other federal payments.
For notices dated April 25, 2025 or later, the default is 50% of your monthly Social Security or SSDI benefit until the debt is repaid. SSI overpayments default to 10%. You can ask for a lower amount with Form SSA-634.
60 days from when you receive the notice to ask for reconsideration on Form SSA-561. SSA assumes you got it five days after the date on the notice. A waiver request on Form SSA-632 has no deadline, but filing within 30 days stops withholding from starting while SSA decides.
An appeal says the overpayment is wrong, in amount or entirely. A waiver accepts it may be right but asks SSA not to collect because you weren't at fault and repaying would cause hardship or be unfair. You can file both.
Yes, if you're not getting benefits it can withhold from and the debt isn't repaid or under an agreement. SSA can refer it to the Treasury Offset Program, which can take federal tax refunds and some other federal payments.
Not necessarily. An SSA error usually means you weren't at fault, which is the first test for a waiver. You still have to show that repaying would leave you unable to meet ordinary living costs or would be unfair, so file Form SSA-632 with a full budget.
