Most retirement planning assumes Social Security is the stable leg of the stool — the payment that arrives on schedule regardless of what markets do. There is one event that breaks that assumption, and it arrives as an ordinary envelope: a Notice of Overpayment saying SSA paid you more than you were owed and wants it back.
This is not a rare administrative edge case. SSA's Inspector General found the agency made nearly $72 billion in improper payments across fiscal years 2015 through 2022 — under 1% of total benefits paid, but a large absolute number — and closed FY 2023 carrying a $23 billion uncollected overpayment balance.
50% Is a Default Setting, Not a Determination
The recovery rate has moved three times in about a year. SSA set it at 10% in March 2024, briefly announced 100%, then settled at 50% for Title II benefits — retirement, survivor, family, and SSDI — on notices dated on or after April 25, 2025. That remains the policy.
Two things about that number matter. First, most earlier Title II overpayments stay capped at 10%, as do all SSI overpayments regardless of date. Second, and more important: 50% is what the system applies when you do nothing. It is not a conclusion about whether you caused the overpayment or whether you can survive the withholding.
For a retiree drawing $1,900 a month with Social Security covering most of fixed expenses, a default setting removing $950 is not a bill — it is an income event with no notice period built into the household budget.
The Three Forms Do Different Jobs
Reaching for the wrong one is the common, expensive mistake.
- SSA-561, Request for Reconsideration — files when you dispute that you were overpaid at all, or dispute the amount. Deadline: 60 days from the notice.
- SSA-632, Request for Waiver — concedes the overpayment happened but asks SSA to forgive it, on the grounds that it wasn't your fault and repaying would be unfair or unaffordable. It can be filed at any time, even after repayment has started.
- SSA-634, Request for Change in Overpayment Recovery Rate — accepts the debt and asks only to pay it back more slowly.
You have a window after the notice to act before withholding begins. Filing a reconsideration or waiver within 30 days generally stops collection from starting at all while SSA decides. Wait, and money comes out while you argue.
Two Provisions Worth Knowing
Since May 2024, SSA's administrative waiver threshold is $2,000 — up from $1,000. Below that, and absent evidence of fault, waiver requires no additional documentation. Separately, SSA will now approve repayment plans stretching up to five years on a verbal summary of income and expenses, without a full financial workup.
Practical Takeaways
- Date the envelope the day it arrives. Every option here is clock-driven, and the strongest one — freezing collection — has the shortest fuse.
- Never ignore a notice to "sort it out later." Silence selects 50%.
- Disputing the debt and asking for mercy are separate filings. You can pursue both; they are not alternatives.
- Stress-test the leg you assume is fixed. If half your Social Security check disappearing for several months would force asset sales at a bad moment, that is an argument for a liquidity buffer you can reach without a taxable distribution.
