You can get Supplemental Security Income (SSI) if you live with an adult son or daughter, or with siblings, cousins or unrelated roommates, for that matter. Such an arrangement can reduce your monthly benefit, however, depending on how much you contribute to certain household costs.
Here’s why: If someone else is partially or fully covering these expenses for you, the Social Security Administration (SSA), which oversees the SSI program, may consider that in-kind income — and income is a factor in calculating benefits.
Each year, Social Security sets a maximum federal benefit for SSI, which provides safety-net payments for people who are 65 and older, blind or have a disability and are in financial need. For 2026, the maximum monthly payment, known as the federal benefit rate, is $1,491 for a married couple if both spouses get SSI and $994 for an individual.
Those figures are starting points. The SSA can reduce and possibly eliminate the monthly payment based on how much you earn from work or receive in cash or direct support from other sources, such as investments, government programs, or relatives and friends.
Shelter costs can affect SSI
Social Security does not factor in all your income in calculating this benefit deduction. For example, the first $20 of most income you receive each month from any source is exempt. So is the first $65 of work earnings each month, and half of any earnings over $65.
The SSA also caps how much your SSI payment can be cut if someone provides you with the agency calls “in-kind support” — formerly defined as help paying for food and shelter but now limited to shelter costs. If you are receiving such support, your SSI payment could be reduced by up to one-third of the federal benefit rate plus $20. In 2026, that’s about $351 for an individual and $517 for a couple.
For the purposes of this calculation, shelter costs include:
- A mortgage, including property insurance required by the mortgage holder
- Real property taxes, less any tax rebate or credit
- Rent
- Trash pickup
- Utilities (that is, heating, gas, electricity, water and sewer)
