If someone else pays your rent, mortgage, or utility bills, the Social Security Administration (SSA) may reduce your Supplemental Security Income (SSI) payment. This is called in-kind support and maintenance (ISM), and it is one of the most misunderstood SSI rules. Understanding how ISM works, which valuation rule applies to your situation, and what changed in 2024 can help you protect your monthly benefit.
The maximum federal SSI benefit in 2026 is $994 per month for an individual and $1,491 for an eligible couple. ISM can reduce those amounts by up to one-third, so the stakes are real.
What Is In-Kind Support and Maintenance (ISM)?
ISM is non-cash help that covers basic needs: food or shelter. When someone gives you food or pays housing costs on your behalf without expecting payment, SSA counts that as unearned income and uses it to reduce your SSI payment.
Shelter costs covered by ISM include:
- Rent or mortgage payments
- Real property taxes
- Heating fuel, gas, and electricity
- Water, sewer, and garbage fees
As of September 30, 2024, food is no longer counted as ISM. SSA removed food from the ISM calculation entirely, regardless of the source. Only shelter-related costs can trigger an ISM reduction starting that date.
The Two Valuation Rules: VTR and PMV
SSA uses two different rules to calculate how much your benefit is reduced. Which rule applies depends on your living arrangement.
Value of the One-Third Reduction (VTR)
The VTR rule applies when you live in someone else's household and that household provides all of your shelter for the entire month. Under VTR, SSA cuts your SSI payment by exactly one-third of the federal benefit rate (FBR).
2026 VTR calculation for an individual:
| Metric | Amount |
|---|
| Full federal benefit rate (FBR) | $994.00 |
| One-third reduction | $331.33 |
| SSI payment after VTR | $662.67 |
When VTR applies, SSA does not add any additional ISM penalty on top of it. The one-third reduction is the maximum hit you take under this rule.
VTR applies only if both conditions are true:
- You live in someone else's household the entire month (not your own residence).
- The household provides all of your food and shelter without charge.
If either condition fails, SSA switches to the PMV rule instead.
Presumed Maximum Value (PMV) Rule
The PMV rule covers all other ISM situations where VTR does not apply. Under PMV, SSA presumes your ISM is worth the maximum possible amount unless you can show it is worth less.
PMV formula:
PMV = (1/3 x FBR) + $20
2026 PMV calculation:
| Component | Amount |
|---|
| One-third of $994 FBR | $331.33 |
| General income exclusion | +$20.00 |
| PMV cap | $351.33 |
2026 SSI payment under PMV:
| Metric | Amount |
|---|
| Full FBR | $994.00 |
| PMV deduction | $351.33 |
| SSI payment after PMV | $642.67 |
The $351.33 is a cap, not an automatic deduction. If the actual value of your shelter assistance is less than $351.33, SSA only counts the actual value and your reduction is smaller.
What Changed in 2024: The Business Arrangement Rule
Before September 30, 2024, if you rented from a family member at below-market rates, SSA treated the difference between what you paid and the current market rental value as ISM. In high-cost cities, this could mean a large ISM penalty even if you were paying a real and reasonable rent.
The new rule replaced the market value standard with the PMV standard for rental arrangements. A valid business arrangement now exists if the rent you pay equals or exceeds the PMV, which is $351.33 per month in 2026. You no longer have to pay market rent to avoid the ISM penalty.
This change primarily benefits SSI recipients who:
- Rent from a parent or adult child
- Pay below-market rent due to a family discount
- Live in high-cost areas where even a reduced rent is well below market value
Under the old rule, a family in a city where market rent is $2,000 per month might face a large ISM penalty if their SSI recipient family member paid only $800. Under the new rule, paying $351.33 or more per month establishes a business arrangement and SSA will not reduce the benefit for the rental subsidy.
2026 SSI ISM Quick Reference
| Rule | When It Applies | 2026 Benefit Reduction | SSI Payment After Reduction |
|---|
| VTR | Live in someone else's household; all shelter provided free | $331.33 (1/3 FBR) | $662.67 |
| PMV | All other ISM situations | Up to $351.33 (capped) | As low as $642.67 |
| New business arrangement rule | Paying rent = PMV or more to family | No reduction | $994.00 (full FBR) |
Public Assistance Household Rule
Another 2024 change affects the public assistance household rule. SSA uses a more lenient income calculation for households where at least one member receives a public assistance benefit such as SNAP, Medicaid, or TANF.
Under the old definition, every household member had to receive a public assistance benefit. The new rule only requires that at least one other household member receives such a benefit. SNAP was also added to the list of qualifying benefits. This expansion makes it easier to qualify for the more favorable income treatment.
Common Situations and How ISM Applies
Living with a family member rent-free
If you move in with a sibling and pay nothing toward rent, utilities, or food, VTR likely applies and SSA reduces your SSI by one-third, down to $662.67 per month.
Living with a family member and paying some expenses
If you pay for some but not all shelter costs, VTR does not apply because the household is not providing all of your shelter. SSA switches to PMV. If the value of what they cover exceeds your general income exclusion ($20), you face the PMV deduction.
Renting below market from a parent
Under the 2024 rule, if you pay your parent $351.33 or more per month in rent, SSA treats this as a business arrangement. No ISM penalty applies and you receive the full $994 FBR.
Someone pays your utility bill as a gift
If a friend pays your electricity bill, that is ISM. SSA counts it under PMV. If the utility bill is $80, only $80 is counted, not the full $351.33 cap.
Living in your own household
If you own or rent your own home and pay your own expenses, ISM does not apply. You receive the full FBR assuming no other income reduces your benefit.
How to Report ISM to SSA
You must report any ISM you receive to SSA. Failing to report can cause overpayments that SSA will collect later, often by withholding future SSI payments.
Report changes by:
- Online: Log in at ssa.gov/myaccount and use the report changes tool.
- By phone: Call 1-800-772-1213 (TTY: 1-800-325-0778), Monday through Friday, 8 a.m. to 7 p.m.
- In person: Visit your local Social Security office. Use the office locator at ssa.gov/locator.
- By mail: Send a letter to your local Social Security office with your name, Social Security number, and a description of the change.
Report changes as soon as they happen, not just at annual redetermination. SSA requires you to report within 10 days after the end of the month in which the change occurred.
Does ISM Affect Medicaid Eligibility?
ISM does not affect your Medicaid eligibility directly. Medicaid eligibility is based on income and resources, and SSI recipients typically qualify for Medicaid automatically in most states. However, if ISM reduces your SSI payment significantly, it is worth confirming with your state Medicaid office whether your modified adjusted gross income (MAGI) or other factors change.
Strategies for Minimizing ISM Reduction
Pay rent equal to or above the PMV. Under the 2024 rule change, paying $351.33 or more per month to a family member qualifies as a business arrangement and eliminates the ISM penalty.
Document your rental agreement. A written lease helps SSA confirm the business arrangement exists. Keep copies of rent payment records.
Contribute to household expenses directly. If you pay your share of utilities, groceries, or other costs yourself, the amount others provide is lower, potentially below the $20 general income exclusion threshold.
Request a formal calculation from SSA. If you believe the actual value of your ISM is less than the PMV, you can provide evidence of the actual value. SSA will use the lower figure.
Use the Benefits Navigator eligibility screener to check whether your current living arrangement may be affecting your SSI amount and what other programs you may qualify for alongside SSI.
Frequently Asked Questions
What is in-kind support and maintenance for SSI?
In-kind support and maintenance (ISM) is non-cash assistance that covers shelter costs such as rent, utilities, or mortgage payments. When someone provides this assistance to an SSI recipient without charging for it, SSA counts it as income and reduces the monthly SSI benefit by up to $351.33 in 2026.
How much does ISM reduce my SSI payment in 2026?
Under the VTR rule, ISM reduces your SSI by one-third of the federal benefit rate, which is $331.33 in 2026. Under the PMV rule, the maximum reduction is $351.33, which is one-third of the FBR plus $20. Your actual payment could be as low as $642.67 per month.
Does food count as ISM in 2026?
No. As of September 30, 2024, food is no longer counted as ISM regardless of who provides it or what it costs. Only shelter-related costs such as rent, mortgage, utilities, and property taxes can trigger an ISM reduction.
What is the PMV for SSI in 2026?
The presumed maximum value (PMV) is $351.33 per month in 2026. This is calculated as one-third of the $994 federal benefit rate ($331.33) plus the $20 general income exclusion.
Does paying below-market rent trigger an ISM penalty?
Not necessarily under the 2024 rule change. If you pay rent equal to or greater than the PMV ($351.33 in 2026) to a family member, SSA considers a business arrangement to exist and will not impose an ISM penalty, even if your rent is far below market value.
Can a family member pay my utilities without reducing my SSI?
If the value of the utility payments is $20 or less per month, the general income exclusion may offset the ISM entirely. If the value exceeds $20, SSA counts the excess as ISM under the PMV rule and may reduce your benefit accordingly.
Does ISM affect SSI eligibility or just the payment amount?
ISM affects the payment amount, not eligibility. Even if you receive significant ISM, you remain eligible for SSI as long as you meet the income, resource, and disability requirements. ISM only changes how much you receive each month.
How do I know which rule applies to my situation?
The VTR rule applies if you live in someone else's household the entire month and that household provides all your food and shelter without charge. In all other ISM situations, the PMV rule applies. If you are unsure, contact SSA at 1-800-772-1213 or visit your local Social Security office.
What happens if I do not report ISM?
Failure to report ISM can result in an overpayment. SSA will calculate the correct payment retroactively and require you to repay the difference, often by reducing future SSI payments. Always report changes in your living situation promptly.
