A parent’s health declines, the rent becomes unmanageable, or living alone stops being safe, and the family does the obvious thing: the parent moves in. If that parent receives Supplemental Security Income, the move can change the amount of the cheque, sometimes substantially, and nobody at the kitchen table usually knows it.
The reason is a rule called in-kind support and maintenance, shortened by Social Security to ISM. SSI is a means-tested benefit, and Social Security treats help with housing that someone receives for free, or below cost, as a form of income. Living rent-free in a child’s home can therefore reduce the SSI payment, and in the most common situation the reduction is a flat one-third of the federal benefit.
This is not a penalty for family care, and it can often be avoided entirely with a small amount of paperwork. It becomes a problem mainly when nobody reports the move, the payment continues unchanged, and a letter arrives months later announcing an overpayment.
This guide applies to SSI only. Social Security retirement and SSDI are not means-tested and are not affected by where the person lives or who pays the rent.
What Counts as In-Kind Support Since 2024
Until September 30, 2024, both food and shelter counted. Social Security then changed the rule so that food is no longer counted as in-kind support. Only shelter counts now.
Shelter, for this purpose, means the costs of keeping a roof over the household: rent or mortgage payments, property tax, and the utilities that make the home habitable, such as heating fuel, gas, electricity, water, sewer and rubbish collection. Things like the telephone, internet, food and household goods are not shelter costs under the current rule.
So the question Social Security asks is, in essence: is this person paying their share of the household’s shelter costs, and if not, how much of that support are they receiving from someone else?
The Two Ways the Reduction Is Calculated
The one-third reduction. When an SSI recipient lives in another person’s household for a full month and receives shelter from that person without paying their share, Social Security generally applies a flat reduction of one-third of the federal benefit rate. It does not matter how large or small the actual value of the help is. It is the same fixed amount for everyone in that situation.
The presumed maximum value. In other situations, for example where the recipient has their own household but someone else pays part of their rent, the value of the help is counted up to a cap known as the presumed maximum value, which is one-third of the federal benefit rate plus $20. If the actual value of the support is lower and the recipient can show it, the lower actual value is used.
Either way, the reduction can be significant for someone whose whole monthly income is SSI.
California’s State Supplement Also Depends on Where You Live
In California, the SSI payment includes a State Supplementary Payment, often called SSP, added by the state on top of the federal benefit and paid in the same deposit. The SSP amount depends on the recipient’s living arrangement, and the categories include independent living, living in the household of another, and non-medical out-of-home care such as a board and care home.
A move into a relative’s home can change the category, and with it the state portion, separately from the federal ISM calculation. When you report the move, Social Security will determine both. It is worth asking the Social Security representative to explain which living arrangement they have recorded and why, and checking it against the facts.
Way One: Pay Your Share
The most straightforward way to avoid a reduction is for the SSI recipient to pay their pro rata share of the household’s shelter costs.
Work it out like this. Add up the household’s monthly shelter costs: the rent or mortgage, property tax if it is paid monthly or divided into a monthly figure, and the utilities listed above. Divide by the number of people living in the household. That figure is the recipient’s share. If the recipient pays at least that amount each month, from their own money, Social Security generally treats them as not receiving in-kind support for shelter.
For a parent moving into a three-person household, that means paying roughly a third of the shelter costs. On a modest SSI income that can still leave more money in hand than a one-third reduction would, and the family receives the payment rather than Social Security keeping it.
Three practical points make this work:
- Pay by a traceable method, such as a transfer from the recipient’s own bank account, and keep the records. A cash arrangement nobody can document will be hard to prove.
- Write it down. A short, signed household agreement stating who lives there, what the monthly shelter costs are, how the share was calculated and what the recipient pays each month is exactly what a claims representative wants to see.
- Keep the underlying bills. Social Security may ask for the rent receipt, the mortgage statement or the utility bills used in the calculation.
Some families prefer to call the payment rent. That is fine, but the arrangement should be real and at a figure you can explain, because a token rent well below the actual share may still leave some in-kind support to be counted.
Way Two: A Written Loan Agreement
Social Security does not count support as income if it is provided as a genuine loan that the recipient is obligated to repay. A family that cannot, or would rather not, collect a monthly share can set up a written agreement in which the recipient promises to repay the value of the shelter they receive, for example from a future inheritance or a later change in circumstances.
To be accepted, the agreement generally needs to be in writing, signed at the time the support begins, and to state the obligation to repay. An agreement written afterwards to explain months that have already passed is much weaker. Social Security looks at whether the arrangement is a real loan or a gift in disguise, so the terms should be clear and both parties should understand them.
A loan agreement adds a debt to the recipient’s affairs that may matter later, including to an estate. Families considering it should read our guide to Medi-Cal estate recovery and, if the sums are significant, speak with a legal aid office or an elder law attorney.
Public Assistance Households
In a public assistance household, Social Security generally does not count in-kind support at all, on the reasoning that the help comes from public funds already means-tested. Alongside the food change in 2024, Social Security expanded what counts as a public assistance household, and the definition now includes households receiving SNAP benefits, which in California is CalFresh.
If your household receives CalFresh or another qualifying means-tested benefit, ask Social Security whether it is treated as a public assistance household, and have the benefit paperwork to hand. For a family where the new household member’s arrival also changes the CalFresh calculation, our guide to the CalFresh medical expense deduction is worth reading, because older and disabled household members often qualify for a deduction that is seldom claimed.
What to Report, and When
SSI recipients must report changes that could affect their payment, and a change of address or of who lives in the household is one of them. Reports are due by the 10th day of the month after the change. Report by phone, at a local Social Security office, or through the online services where available, and keep a note of the date, the name of the person you spoke to and any reference number.
When reporting a move into a relative’s home, have ready: the new address, the date of the move, the names of everyone in the household, the monthly shelter costs and, if you are using one, the household agreement or loan agreement.
If the recipient’s payment was reduced and the facts change later, for instance they begin paying their share, report that too so the payment can go back up.
If an Overpayment Letter Has Already Arrived
A move that was never reported can produce a notice of overpayment covering every month since the move. It is not the end of the road.
- Check the facts. Was the reduction applied to the right months? Was the living arrangement recorded correctly? Were shelter payments the recipient did make taken into account?
- You can appeal the decision that an overpayment exists or its amount, by requesting reconsideration within the time limit stated on the notice.
- You can ask for a waiver, which means asking Social Security not to recover the overpayment, on the grounds that the recipient was not at fault and that repayment would defeat the purpose of the benefit or be unfair. A waiver request can be made at any time.
- You can ask for a lower repayment rate if Social Security is recovering the money by withholding from future payments and that withholding leaves the recipient unable to meet basic needs.
Legal aid offices and disability rights organisations help with SSI overpayments regularly and without charge for people within their income limits.
How This Interacts With Medi-Cal and IHSS
In California, receiving SSI generally brings Medi-Cal with it. A reduction in the SSI payment does not in itself end Medi-Cal, so long as some SSI is still paid. If a change in circumstances ended SSI entirely, Medi-Cal eligibility would need to be established on another basis, and it is worth asking the county about that at once rather than waiting for coverage to lapse.
A parent who moves in may also qualify for In-Home Supportive Services, and a relative in the household can often be the paid provider. IHSS wages are the provider’s income, not the recipient’s, so they do not reduce the recipient’s SSI. Our guide to how IHSS and Social Security disability interact covers the benefit side for the recipient, and our guide to paying a family member to provide care covers arrangements outside IHSS, which must be in writing to avoid a different set of problems.
The Part Nobody Plans For
Moving a parent in usually solves the housing problem and creates a care problem. Families who take this on often find that the hours of help needed grow faster than anyone expected, and that the relative doing most of the care needs cover for work, for appointments and for rest. IHSS, respite through the Area Agency on Aging and adult day programmes can help, and many families also end up looking for a caregiver to fill particular hours. Care Royal (from the same team as Unified Savers) is building a marketplace for families looking for caregivers and is currently taking names on a waitlist; it is not yet open for bookings.
Whoever provides care, the arrangement should be written down, the IHSS or private agreement should be clear about hours and pay, and the SSI side should be reported, so that the move that was meant to make life easier does not produce a debt a year later.
The Short Version
If a relative on SSI moves in and lives rent-free, Social Security can count the free shelter as income and, in the most common case, cut the federal payment by a third. Food no longer counts, only shelter. Avoid the reduction by having the recipient pay their share of the household shelter costs from their own account, recorded in a simple written agreement, or by a genuine written loan agreement signed when the support begins. Ask whether the household counts as a public assistance household, particularly if it receives CalFresh. Report the move by the 10th of the following month. And if an overpayment letter has already arrived, check the months, and consider an appeal, a waiver request or a lower repayment rate.
