A retiree who started Social Security benefits has 12 months to change their mind, but only by paying back what came in. The agency’s withdrawal page, updated Sept. 29, 2026, says people can cancel an application up to 12 months after approval and can reapply later. It also says the cancellation is allowed only once.
Repayment is the catch. If payments have already started, the same page says, the person must return the money they and their family received. Social Security’s operations manual spells out that the repayment has to happen before the agency approves the withdrawal.

What exactly gets paid back?
More than the monthly deposits. The agency says the repayment includes amounts it withheld for Medicare premiums, for taxes and for garnishments. If Medicare Part A paid for medical costs during the period, those costs must be repaid to Medicare as well.
The manual, in its section on withdrawal requirements, describes the same list: Medicare hospital expenses paid by the Centers for Medicare & Medicaid Services, Part B premiums withheld by Social Security, and voluntary tax withholding for tax years that have closed. A written statement of offset payments can cover the repayment when it can be fully offset against another benefit type.
So the total owed back is not just the sum of the deposits. It also takes in what was held out of the checks and any Medicare payments made for the person’s care during the year.
Who else has to sign off?
Other people can be on the same record. The manual says every beneficiary whose entitlement would be wiped out by the withdrawal must give written consent before the agency can approve it. Independently entitled divorced spouses are the exception, and the agency does not ask them for consent.
The withdrawal page says the repayment covers money the family received, so a spouse or child drawing on the retiree’s record is part of the calculation.
If deemed filing applies, the manual adds, the claimant has to withdraw both applications. A person born on or after Jan. 2, 1954 who filed for a retirement benefit and a spousal benefit together cannot pull back only one.
Why would someone undo a claim?
Usually to start over at a higher monthly amount. Social Security’s January 2026 Retirement Benefits booklet says a person who turns 62 in 2026 would get a benefit about 30% lower than at a full retirement age of 67. It also says the agency adds 8% for each full year a person delays past full retirement age, until benefits start or the person reaches 70.
A claim made early locks in the reduction. Withdrawing inside the window and repaying clears the claim, and the person can file again at a later age under the same rules as anyone else.
How does the 12 months get counted?
The withdrawal page counts from approval of the benefit. The operations manual counts from the first month of entitlement, saying a person getting a retirement benefit must submit the request within 12 months of that month.
The once-in-a-lifetime limit is in the manual too. A person receiving retirement benefits is limited to one approved withdrawal, though a request made before the agency has decided the claim does not use up that one. Social Security’s answer on withdrawing and reapplying, last dated March 2024, says only that a person may be able to withdraw when less than 12 months have passed since first entitlement and may reapply at a future date.
How is a withdrawal requested?
The request goes on Form SSA-521, Request for Withdrawal of Application. According to the withdrawal page, a person can sign in and complete it online, download the PDF and mail it to the nearest Social Security office, or call 1-800-772-1213 from 8 a.m. to 7 p.m. local time on weekdays and say they want to cancel the application. The TTY number is 1-800-325-0778.
The manual calls for a written request, preferably on that form, that names the benefit and gives a clear reason. A faxed request does not meet the signature requirement, it says, and the request has to be filed during the claimant’s life, with exceptions the manual sets out separately.
The agency’s page says only that a person can reapply later. The monthly amount on a new claim is set by the agency when the new application is made.
The July 2026 edition of Form SSA-521 asks for a reason: an intent to continue working, or “other,” explained in full. It also asks whether the person wants to keep Medicare benefits, and it is signed under penalty of perjury.
The form states what approval does. The earlier decision has no legal effect, the claimant gives up rights tied to the application, including appeal rights, and a later application may not cover the same retroactive period. Anyone whose benefits would be affected must consent. Crediting of wages to the earnings record is not affected, the form says.
Thinking about undoing a Social Security claim?
Paying back a year of checks means returning the deposits, the Medicare premiums and the withheld taxes, and the move can be made only once. A retiree who undoes the claim without a plan for the gap can end up short on the very bills the checks covered.
The step from this rule to the rest of a retirement budget is a plain one: Social Security is where the money starts, and Medicare is one of the places it leaks. The Keep-It Starter Bundle puts nine guides in one 95-page download, including how to cut Medicare costs: appeal the income surcharge and use the drug cap, alongside the guide on making savings pay without risk you don’t understand.
