Many older Americans treat a Social Security check as money that no one can touch. For the debts most retirees actually carry, that instinct is correct: a credit-card issuer or a hospital collection agency generally cannot pull a dollar out of a monthly benefit. Federal law, though, keeps a short list of obligations that can still reach that payment. For someone living close to the edge, a reduced check can arrive with little warning, so it is worth knowing exactly which debts qualify and how much they can take.
The general rule: shielded from most creditors
Social Security retirement and disability benefits sit behind a strong legal shield when the debt is commercial. Credit cards, medical bills, personal loans, and most old accounts turned over to collections cannot be used to garnish a benefit, and money that is clearly identifiable as Social Security keeps some protection even after it is deposited into a bank account. That is the reason a private judgment rarely turns into a smaller monthly payment.
The exceptions all share a trait: each one traces back to a government debt or a court order rather than to a private company. According to the Social Security Administration’s guidance on garnishment, benefits are generally protected from ordinary creditors but can be reduced to satisfy a handful of specific obligations. Knowing those categories is what separates a false alarm from a real threat to a fixed income, and in almost every case a reduction is preceded by written notice rather than a surprise withdrawal.

Unpaid federal taxes
The most common exception involves money owed to the IRS. Through the Federal Payment Levy Program, the federal government can place a levy on a monthly Social Security benefit to collect delinquent federal taxes. The levy generally takes up to 15 percent of the payment, and it continues until the tax debt is resolved or another arrangement is reached.
Because the amount is capped as a percentage rather than a flat seizure, a retiree usually keeps the bulk of the check, but 15 percent of a modest benefit is still a meaningful loss. Anyone who receives a notice about a pending levy has a window to respond, set up a payment plan, or claim a hardship before the reduction begins, which is why ignoring IRS mail is the costliest move a beneficiary can make.
The levy is also continuous rather than a one-time grab. Once it is in place, it applies to each monthly payment until the balance is cleared or a formal agreement pauses it. That makes early contact with the IRS the difference between a temporary reduction and one that stretches across many months of retirement income.
Defaulted student loans and other federal debts
Federal student loans in default fall under a separate collection tool called the Treasury Offset Program, which the Department of the Treasury uses to recover many kinds of delinquent, non-tax debts owed to the government. When a benefit is offset to repay a defaulted federal loan or another qualifying federal debt, the reduction is also limited to 15 percent of the monthly payment.
The program carries an extra protection for the lowest-income recipients: an offset generally cannot push a monthly benefit below a floor of 750 dollars. A borrower who defaulted on a federal student loan decades earlier can still see that debt resurface in retirement, and older Americans who co-signed loans for children or grandchildren are sometimes surprised to learn their own benefit is exposed.
There is usually a way out. Borrowers who bring a defaulted federal loan back into good standing, through rehabilitation or another repayment arrangement, can stop the offset going forward, which is why acting on the first Treasury notice matters as much here as it does with a tax levy. The reduction is a symptom of an unresolved federal debt, not a permanent feature of the benefit.
Child support, alimony, and court-ordered restitution
Court orders form the third category. A Social Security benefit can be garnished to satisfy court-ordered child support or alimony, and it can also be tapped to pay court-ordered victim restitution in a criminal case. These garnishments follow the terms set by the court rather than the flat cap that applies to federal tax and non-tax debts, so the amount withheld depends on the order and on state limits for support obligations.
Support garnishments can also reach deeper than the ceiling that governs tax levies and Treasury offsets. Because they follow long-standing family-law rules, a court order for child support or alimony can claim a larger share of a check than the 15 percent limit that applies to most federal debts, with the exact figure depending on state law and on whether the person is also supporting another family. For retirees, this category most often appears through orders that never ended or through arrears that piled up years before benefits started, and the obligation does not disappear simply because a person has stopped working.
Supplemental Security Income is treated differently
One federal benefit stays off the table entirely. Supplemental Security Income, the needs-based program for older, blind, and disabled people with very low income and few assets, is exempt from these offsets and garnishments. Because SSI exists to cover basic needs, it is not subject to the federal tax levy, the Treasury offset, or garnishment for support. Retirees who receive SSI, or a combination of SSI and a small Social Security benefit, should know that the SSI portion carries this stronger protection.
What the exceptions add up to
The pattern behind the rules is consistent. Social Security is protected from the private debts that pile up most easily and exposed only to obligations the government or a court has already established. Unpaid federal taxes, defaulted federal student loans, and court-ordered support or restitution are the doors that stay open, each with its own cap and its own process. For an older reader building a retirement budget, the practical lesson is to treat any federal notice about a levy or offset as urgent, since responding early is almost always what preserves the check.
