A family loan can quietly cost someone their SSI check, and it has nothing to do with interest rates. If your relative receives Supplemental Security Income and you lend them cash, the loan itself is not counted as income as long as it meets Social Security's "bona fide loan" test. But any part of that money still sitting in their account on the first moment of next month counts as a resource, and SSI cuts off entirely above $2,000 for an individual or $3,000 for a couple. Miss that detail and a well-intentioned $4,000 loan can end a benefit that took months to qualify for.
This is a narrower, sharper question than the general "should I lend money to family" decision. It only applies to Supplemental Security Income, and it hinges on a specific five-part test the Social Security Administration (SSA) applies to informal loans between relatives.
SSI vs. SSDI: A Family Loan Only Threatens One of Them
People say "I'm on disability" to describe two very different programs, and mixing them up leads to bad advice.
Social Security Disability Insurance (SSDI) is an earned benefit tied to your work history and FICA contributions. It has no resource or asset limit. A $10,000 loan sitting in an SSDI recipient's checking account changes nothing about their eligibility.
Supplemental Security Income (SSI) is a needs-based program for people with limited income and resources, disabled or not. As of 2026, the countable resource limit is $2,000 for an individual and $3,000 for a couple, a figure that has not moved since 1989. This is the program where a family loan can cause real damage if it is not handled correctly.
If you are not sure which program your relative receives, check their award letter before doing anything else. Everything below applies to SSI only.
The SSI Bona Fide Loan Test: SSA's 5-Part Checklist
Under SSA policy (POMS SI 01120.220 and SI 00815.350), the proceeds of a loan are not income to the borrower, because the borrower is legally obligated to repay them. That protection only holds if the loan is "bona fide." SSA checks five things:
- The agreement must be enforceable under state law. An oral agreement can qualify in most states, but a written one is far easier to prove.
- The agreement has to exist before the money changes hands. You cannot hand over cash today and paper it as a loan next month. SSA treats that as a gift with a story attached.
- Both sides must acknowledge a real obligation to repay. A statement like "I'll pay you back if I can" does not create a legal obligation and fails this test.
- There has to be an actual repayment plan or schedule, tied to a specific source, such as future income, a pending settlement, or the sale of property.
- The repayment plan has to be feasible, meaning realistic given the borrower's income, other resources, and living expenses.
All five have to hold at the same time. Miss one, and SSA can treat the entire amount as unearned income in the month it was received, which reduces or eliminates the SSI payment for that month outright.
Interest charged on the loan, if any, is taxable income to the lender no matter which way the bona fide determination goes. That side of the transaction runs through IRS rules, not SSA's, and it is worth reading what counts as a family loan for IRS purposes if you are also charging interest.
The Real Trap Isn't the Loan. It's What's Left Over
Here is where families get caught, even when the loan itself is textbook bona fide.
SSA measures resources at the first moment of each calendar month. If your countable resources exceed the limit at 12:01 a.m. on the first, you lose SSI for that entire month, even if you spend the money down to zero later that same day.
Worked example. Say your sister receives SSI and her car needs a $3,500 transmission repair in March. You wire her $3,500 on March 10, with a signed agreement, a repayment date, and monthly payments starting in June from her part-time income. The loan itself is not income, so March is unaffected on that front. But she only spends $2,000 on the repair and related costs, and the paperwork gets delayed. On April 1, she still has $1,500 of loan proceeds sitting in her checking account, on top of whatever she already had. If that combined total tops $2,000, she is over the resource limit for April and loses her SSI payment for the month, regardless of how bona fide the loan was.
The fix is not complicated, just easy to miss: spend loan proceeds down to the resource limit before the month ends, or have the funds arrive close enough to when they will actually be used that nothing carries over.
If Your Relative Is the One Lending Money
The trap runs the other way too. If someone receiving SSI lends money to a family member, the amount owed to them becomes a resource, an asset called a "loan receivable," and it is generally counted at face value unless it is unsaleable or the SSI recipient cannot practically enforce repayment. A parent on SSI who lends a grandchild $5,000 for tuition can put their own benefit at risk exactly the same way, just from the opposite side of the transaction. Anyone in this position should talk to a benefits planner before either side of the transaction happens, not after.
Documentation That Actually Holds Up
SSA reviews the loan against state contract law and the five-part test above, which means the documentation has to look like a real loan, not a gesture.
- Put it in writing and have both parties sign it, even for a small amount. Oral agreements are legally permitted but far harder to prove during an SSA resource review.
- Date it correctly. The agreement must be signed on or before the day the money is transferred.
- Spell out a repayment schedule with real numbers, not "whenever you can." Tie payments to a specific income source and a start date.
- Keep it separate from other family transfers. Mixing a loan with a birthday gift or holiday money in the same transaction muddies the paper trail SSA will ask for.
A generic IOU written on a card is not enough for this purpose. Setting up a proper family loan agreement covers the mechanics of principal, repayment schedule, and signatures that make an informal loan defensible, and you can create a free loan agreement with those terms built in rather than drafting one from scratch.
Report It. SSA Will Find Out Either Way
Bona fide or not, a loan is a change in circumstances, and SSI recipients must report it. The standard deadline is 10 days after the end of the month in which the change happened. If your relative receives loan funds in March, the report is due by April 10.
Skipping this is not a shortcut. SSA cross-checks bank records and tax data, and unreported changes routinely surface later as overpayments, which come with their own repayment demands on top of a $25 to $100 penalty per unreported change. Reporting the loan when it happens, with the signed agreement in hand, is the version of this that goes smoothly.
Where This Overlaps With Other Family Loan Rules
SSI is one of several places where the government looks past the "it's just family" framing and applies a formal test to an informal loan. The Medicaid long-term care look-back period runs a similar but distinct check when an aging parent moves assets before applying for nursing home coverage, and the two programs do not use the same rules or the same clock. If your family is navigating both an SSI recipient and a parent planning for long-term care, read how the Medicaid look-back period treats family loans separately. Do not assume passing one test satisfies the other.
A Narrow Alternative Worth Knowing About
For an SSI recipient who repeatedly bumps against the resource limit, an ABLE account is worth a look before the next loan. In 2026, up to $20,000 a year can go into an ABLE account for an eligible person with a disability without counting against the SSI resource limit, a change from prior years when the cap tracked the federal gift tax exclusion. It will not solve every situation, particularly for one-time expenses that need to be spent immediately, but for ongoing family support it avoids the monthly spend-down math entirely. A special needs or elder law attorney can tell you in one conversation whether it fits your situation better than a loan does.
None of this is tax or legal advice. SSI rules are applied county by county through local field offices, and state contract law affects whether an oral agreement will actually hold up. Before you wire money to a relative on SSI, a 30-minute call with a benefits planner or elder law attorney is cheaper than losing a month of benefits over a paperwork gap.
Track It Once You've Got the Paperwork Right
Once the loan is properly documented and the repayment schedule is set, the easiest way to keep both sides honest, and to keep a clean record if SSA ever asks, is to start tracking the loan with actual due dates and payment history instead of a spreadsheet nobody updates.
