Supplemental Security Income is paid on the basis of what Social Security knows about a recipient’s money, home and household. When something changes, the agency has to hear about it quickly or the monthly payment can be wrong. The reporting deadline is a short one, and it is counted in an unusual way.
The question for a recipient who moved last month, got married or started a job is when Social Security has to be told. SSA’s own reporting page gives the rule in a single sentence.

Ten days after the month ends, not after the change
SSA’s SSI reporting page says changes must be reported “no later than 10 days after the end of the month in which the change occurred.” The ten days start when the month closes, not on the day of the move, the wedding or the first paycheck.
A recipient who moves on October 3 therefore has until November 10 to report it, and one who moves on October 29 has the same date. The practical effect is that every change within a calendar month shares one deadline, which falls in the first ten days of the next month.
The page adds that changes should be reported sooner if possible. Counting from the end of the month gives a margin, but the agency does not treat that margin as a reason to wait.
A move, a marriage or new income all count
SSA lists the changes recipients must report. They include a new address, living arrangement or household members, including a death in the household or of a spouse. Marital status is on the list, and so are earned or unearned income, with a spouse’s income counted if the couple lives together.
Resources are covered as well, including new ones, ones that were sold or transferred, and changes in value. The page also names help with living expenses from friends or relatives, eligibility for other benefits and payments, and admission to or discharge from an institution such as a hospital or nursing home.
Several narrower events appear too: a change in citizenship or immigration status, school attendance changes for recipients under 22, and leaving the United States for a full calendar month or 30 or more consecutive days. Recipients with a disability must also report medical improvement and starting or stopping work, along with changes in pay or hours.
What happens when a change goes unreported
SSA’s page lays out the consequences. A recipient may be underpaid and receive benefits later than otherwise, or may be overpaid and have to pay the money back. Failing to report a change, or reporting it more than 10 days after the end of the month, “may reduce your SSI payment by $25 to $100 each time.”
The page also describes sanctions for people who knowingly make false or misleading statements or knowingly fail to report important changes. Payments may be withheld, starting with 6 months, then 12 months, then 24 months.
SSA’s overpayment page, published July 21, 2025, explains how the debts begin. It says overpayments occur because of missing or wrong information, and that this can happen “if you don’t tell us about changes in your life.” If the money is not repaid within 30 days of the notice date, SSA will automatically withhold 10% of an SSI payment each month.
Where the report goes
The reporting page does not itself say how to report by phone, online, by app or by mail. It points readers to SSA’s contact options instead. SSA’s contact page lists the National 800 Number, the online my Social Security account, an office locator and mailing options.
Because the deadline is tied to the month, a recipient benefits from keeping a record of the date and method of each report. Proof that a change was reported inside the window is the best defense if a payment is later questioned.
A report made close to the deadline is easiest to document online or in writing, since a phone call leaves no copy unless the agency provides a receipt. The contact page does not describe receipts, so the safest habit is to note the date, the person spoken to and what was said.
Two cases that catch recipients out
The first is a move that does not seem like a financial event. A change of address or a new person joining the household shows up on SSA’s list because living arrangements can change how much SSI is paid. A recipient who moved last month and said nothing may still be inside the window if it is not yet the tenth of the next month.
The second is income that arrives irregularly. Unearned income, such as help from a relative, and a spouse’s income both appear on the list. A recipient who waits for a pattern to emerge before reporting can miss the deadline for the first month.
Anyone who has already passed the window can still report. The consequence on the page is a reduction of $25 to $100 each time, and the earlier the report, the smaller the chance of a larger overpayment building up behind it.
Did last month’s move or new income already start the 10-day clock?
An SSI recipient who moves, marries or takes on new income and reports it after the 10th of the next month risks a $25 to $100 reduction and an overpayment that SSA later withholds from the monthly check. The deadline is counted from the month’s end, so one missed date can cover several changes at once.
The SSI & Disability Action Kit includes the 2026 SSI income and resource limits, review and reporting steps, and an income and resource organizer. Part 5, Reviews, Reporting and Overpayments, covers what to send SSA and when.
