When a young person with a disability turns 18, Social Security must review their SSI disability under adult rules, and parents’ income stops counting toward SSI from the month after the birthday. For New York Medicaid in 2026, the limit for one disabled adult is $1,836 a month in income and $33,038 in resources. Decision-making, school services and any home care plan change at the same time, so it helps to start about a year ahead.
What happens to Medicaid and SSI when my child turns 18 in New York?
Two systems act on the birthday, and they work on different clocks. Social Security handles SSI. The state and your local social services office handle Medicaid.
For SSI, the Social Security Administration’s own operations manual says it must redetermine disability for anyone who received SSI based on disability in the month before turning 18. The review happens during the one-year period that begins on the 18th birthday, and it uses the adult definition of disability. Social Security’s manual also says parental deeming, the rule that counts a parent’s income against a child, ends effective with the month after the child turns 18. After that, only the young adult’s own income and resources are counted for SSI.
For Medicaid, the state publishes income and resource standards that apply to adults who are disabled. We did not find an official New York page that spells out how a household is counted for a young adult who still lives with parents, so ask your local Medicaid office (in New York City, HRA) how your child’s case will be handled at 18 rather than assuming. Open every letter from Social Security or Medicaid and answer by the date on it.
What are the 2026 Medicaid income and resource limits for a disabled adult?
These are the New York State figures effective January 1, 2026, from the Department of Health’s standards chart for people who are not subject to the “MAGI” income rules (people who are disabled, blind or 65 and older).
| Category (2026) | Monthly income, 1 person | Monthly income, 2 people | Resource limit, 1 / 2 people |
|---|---|---|---|
| Disabled, blind or 65+ (SSI-related Medicaid) | $1,836 | $2,489 | $33,038 / $44,796 |
| Most adults under 65 (MAGI rules) | $1,836 (138% of the federal poverty level) | $2,489 | No resource test |
If a person’s income is above the Medicaid level, they may still qualify through the state’s Excess Income program, sometimes called spend-down. The Department of Health says you must be under 21, 65 or older, certified blind or certified disabled, pregnant, or the parent of a child under 21 to use it. Many families also look at a pooled trust for the same problem, which we explain in our pooled trust guide and in our spend-down guide.
Who makes decisions after 18? Guardianship and the alternatives
At 18, parents no longer sign for a young person by default. Whether your son or daughter can sign their own papers depends on their capacity, and there is a range of tools between “nothing” and court guardianship.
| Tool | What it does | What the sources say |
|---|---|---|
| Health care proxy | Names a health care agent to make medical decisions if the person cannot. | The Department of Health says everyone over age 18 should have a health care agent. |
| Power of attorney | Lets an agent handle money and property matters. | New York law requires it to be signed by a principal “with capacity,” acknowledged before a notary and witnessed by two people. |
| Supported decision-making agreement | The young adult keeps decision-making power and chooses supporters to help. | Mental Hygiene Law Article 82 calls it a less restrictive alternative to guardianship. The law takes effect on a schedule tied to state regulations, so confirm with OPWDD that it is available to you. |
| Guardianship under SCPA Article 17-A | A court appoints a guardian for a person with an intellectual or developmental disability. | The statute requires certification, by one licensed physician and one licensed psychologist (or two physicians), that the person cannot manage themselves or their affairs and that the condition is permanent or likely to continue indefinitely. A 2025 bill from the court system would rewrite this article, so check the current law with an attorney. |
Our guide to power of attorney and guardianship goes further on how each one works. For the exact signature format agents use, see how to sign as POA in New York. A family attorney or a legal aid office that works with disability cases is the right person to pick between these, not a home care agency.
What changes at school, with OPWDD and with a home care plan?
School. New York State Education Department guidance says that beginning with the first IEP in effect when a student turns 15, the IEP must include measurable postsecondary goals and the transition services needed to reach them. When a student leaves school with a diploma or credential, or ages out, the district must provide a written exit summary of achievement and functional performance. On how long school services last, the education law says the end of the school year in which the student turns 21, but the Department’s own FAPE page tells districts to provide services to students without a diploma up to age 22. Ask your district which date it is applying.
OPWDD. If your young adult is eligible for services from the Office for People With Developmental Disabilities, the Department of Health’s managed care chart lists OPWDD-eligible individuals as exempt from mainstream Medicaid managed care. That means they can choose to join but are not required to. We could not open OPWDD’s own pages for this article, so use opwdd.ny.gov or your regional office to confirm the eligibility steps.
Home care. A 2025 rule matters here. According to the Department of Health, the Minimum Needs Requirement applies to Medicaid recipients 21 and older seeking Personal Care Services or CDPAP, and to everyone 18 and older who wants to join a Medicaid Advantage Plan or Managed Long Term Care plan. In plain terms, the person must be assessed as needing at least limited assistance with physical maneuvering for more than two activities of daily living, or, with a dementia diagnosis, supervision with more than one. It does not apply to PACE. Managed Long Term Care is open on a voluntary basis to non-dual adults age 18 and over who are assessed as needing community-based long-term care for more than 120 days at a nursing-home level of care. Our guides to CDPAP eligibility and what Medicaid covers for home care explain how the assessment works.
What should we do in the year before the 18th birthday?
- Gather records. Keep current evaluations, school records, diagnoses and doctors’ letters together. You will want them at hand if Social Security asks for updated information.
- Ask Social Security about the age-18 review. If your child gets SSI on disability, find out when the review will happen and who should receive the mail.
- Ask your Medicaid office how your child’s case will be counted at 18, and what income and resources they will want to see. Compare any savings in the child’s name with the $33,038 limit.
- Pick the decision-making tools. Talk to an attorney about a health care proxy, power of attorney, supported decision-making or guardianship, and do it before the birthday if guardianship is likely.
- Check the school plan. Make sure the IEP has real postsecondary goals, ask for the exit summary, and ask which end date the district uses.
- Find adult providers. Start looking for adult doctors and ask the current ones when they will stop seeing your child. Ask about OPWDD eligibility if it applies.
- Plan for personal care. If your young adult will need help with bathing, dressing, meals or medication, ask about the Minimum Needs assessment early.

Frequently asked questions
What happens to Medicaid when my child turns 18 in New York?
Social Security reviews SSI disability under adult rules within a year of the 18th birthday, and parents’ income stops being counted for SSI the month after the birthday. For Medicaid, the 2026 limit for one disabled adult is $1,836 in monthly income and $33,038 in resources. Ask your local Medicaid office how your child’s household will be counted.
Will my child lose SSI at 18?
Not automatically. Social Security must redetermine disability using the adult definition, so some young people are found no longer disabled. If that happens, ask Social Security how to appeal before the deadline in the notice.
Do parents’ income and savings still count after 18?
For SSI, Social Security’s manual says parental deeming ends effective with the month after the child turns 18. For Medicaid, the household rules are set by the state, so confirm with HRA or your county social services office rather than assuming.
Do we need guardianship when our child turns 18?
Not always. A health care proxy, a power of attorney signed with capacity, or a supported decision-making agreement may be enough for some young adults. Article 17-A guardianship requires physician and psychologist certification and a court order, so it is worth a consult with an attorney first.
When does the Minimum Needs Requirement apply at 18?
The Department of Health says it applies to anyone 18 or older who wants to enroll in a Medicaid Advantage Plan or Managed Long Term Care plan, and to people 21 and older seeking Personal Care Services or CDPAP. It does not apply to PACE.
How long do school services last for a student with a disability in New York?
State law says to the end of the school year in which the student turns 21, but the State Education Department’s FAPE page tells districts to provide services to students who have not earned a diploma up to age 22. Ask your district which date it uses and ask for the exit summary when services end.
Can a pooled trust help a young adult keep Medicaid?
It can help some people whose income is above the Medicaid level. The rules are specific, so read our pooled trust guide and speak with the trust or an elder-law or special-needs attorney before depositing income.
