Maryland Disability Benefits Checklist: What to Do When Your Child Turns 18

The Age-18 Cliff Hits Five Agencies at Once

When a Maryland teenager with a disability turns 18, the transition isn't one event — it's a collision of federal and state deadlines across the Social Security Administration, Maryland Medicaid, the Developmental Disabilities Administration, the Division of Rehabilitation Services, and the school system. Missing any single filing window can disrupt benefits that took years to establish.

Here's the chronological sequence, organized by when each action needs to happen.

Before Age 18: The Setup Phase

At age 14: Maryland law requires IEP transition planning two years earlier than the federal default. This IEP must include measurable postsecondary goals in employment and education. Separately, submit the DDA Application for Eligibility — the DDA and school systems don't share data, so an active IEP does not register your child with the DDA. Also request DORS Pre-Employment Transition Services, which are available without a formal eligibility determination.

At age 16: Ensure the IEP includes a coordinated set of transition activities linking to adult service providers. Begin formal DORS Student Employment Services if your child is interested in supported employment or job coaching.

At age 17: Evaluate decision-making options. Maryland's Supported Decision-Making Act (effective October 2022) provides a legally recognized alternative to guardianship under Estates & Trusts §§ 18-101 to 18-109. If guardianship is necessary, start the circuit court petition process — it requires two clinical certificates of incapacity and takes months.

At age 17.5: The school must notify you about transfer-of-rights rules. Under COMAR 13A.05.01.11B, Maryland parents who reside with their adult child retain educational decision-making rights without guardianship — unlike nearly every other state.

The Month of the 18th Birthday

File the adult SSI application. The SSA treats this as a new application under adult disability standards, not a continuation of childhood SSI. Parental income deeming ceases entirely — your child's eligibility is now assessed solely on their own income and assets. The key forms are SSA-3368 (Adult Disability Report), SSA-3369 (Work History Report), and SSA-3373 (Function Report).

Draft a pro-rata rent agreement. If your adult child lives with you and receives SSI, a written agreement documenting their fair-share contribution toward rent and utilities prevents the SSA from reducing the SSI payment through In-Kind Support and Maintenance calculations. Since late 2024, food is no longer counted as ISM — but shelter charges still are.

Confirm Medicaid continuity. Maryland is a Section 1634 state, meaning SSI approval automatically triggers Medicaid enrollment through electronic data transmission. If SSI is denied, you'll need to apply separately through the myDHR portal under the non-MAGI Aged, Blind, and Disabled pathway. The 2026 Maryland ABD asset limit is $2,500 for an individual.

Open a Maryland ABLE account. Up to $100,000 in ABLE savings is excluded from the SSI $2,000 resource limit. The 2026 annual contribution limit is $20,000 standard, with an additional $15,650 available through the ABLE to Work provision for employed beneficiaries not contributing to an employer retirement plan.

After Age 18: Ongoing Monitoring

Monitor the DDA waiting list. Your assigned Coordinator of Community Services (CCS) provides case management while your child waits for waiver funding. CCS contact frequency depends on priority category: monthly for the first 90 days of Crisis Resolution, quarterly for Crisis Prevention, annual for Current Request. If circumstances change — caregiver health decline, housing instability, behavioral crisis — request a priority category reassessment through the CCS.

Track the SSI redetermination outcome. If SSA issues a cessation notice, you have 60 days to file a Request for Reconsideration. Filing within 10 days of the notice date preserves benefit continuation (both cash and Medicaid) during the appeal.

Plan for age 21. FAPE entitlement ends at the conclusion of the school year in which your child turns 21. The Governor's Transitioning Youth Initiative provides one year of dedicated DDA day and employment funding starting from the graduation date — submit the application before the student exits school.
