Understanding SSDI and SSI: What These Programs Are

Social Security Disability Insurance (SSDI) and Supplemental Security Income (SSI) are two different government programs that provide monthly payments to people with disabilities. While they serve similar purposes, they work in different ways, and it's important to understand how each one functions.

SSDI is a program for people who have worked and paid into Social Security, or whose parents or spouses have worked and paid into Social Security. When a worker becomes disabled and cannot work, SSDI may provide monthly payments based on their work history. The amount of the payment depends on how much that worker (or their parent or spouse) earned during their working years. SSDI also extends to children of workers who have retired, become disabled, or died.

SSI is different. This program is for people with limited income and resources, regardless of their work history. SSI payments go to disabled children and adults, as well as elderly individuals. Because SSI is need-based, the amount someone receives depends on their income and how many resources they own, not on their work history.

For children specifically, both programs may offer support. A child may receive SSDI payments based on a parent's work record if that parent is disabled, retired, or deceased. A child may receive SSI if they have a disability and their family's income and resources fall within certain limits. According to the Social Security Administration, as of 2024, approximately 7.5 million children receive benefits through one of these programs.

Understanding which program might apply to a child's situation is an important first step. The guide explores the differences between these programs in detail, helping families understand what each one provides and how they differ in terms of income limits, payment amounts, and work incentives.

Practical Takeaway: SSDI is work-history based, while SSI is need-based. A child might receive either one or potentially both, depending on their family's circumstances and the child's disability.

Medical and Functional Requirements for Children

Both SSDI and SSI require that a child have a condition that meets the Social Security Administration's definition of disability. For children, disability means a physical or mental condition that causes marked and severe functional limitations and can be expected to last at least 12 months or result in death.

Social Security uses a specific list called the "Listing of Impairments" to evaluate disabilities. This list includes conditions in categories such as musculoskeletal disorders, special senses and speech, respiratory system disorders, cardiovascular system, digestive system, genitourinary system, hemic and lymphatic system, skin disorders, endocrine system disorders, neurological disorders, mental disorders, immunological disorders, and malignant neoplastic diseases. The list is detailed and specific. For example, under neurological disorders, conditions like cerebral palsy, epilepsy, autism spectrum disorder, and traumatic brain injury are included.

However, a child doesn't need to have a condition that exactly matches the Listing of Impairments to receive benefits. Social Security can also look at whether a child's condition, even if not on the list, causes functional limitations that are equally severe. This is called meeting the "spirit" of the Listing.

Functional limitations are what matter most. These are things a child cannot do because of their condition. Examples include difficulty communicating, trouble learning, problems with self-care, limitations in movement or coordination, behavioral difficulties, or trouble with social functioning. A child with autism, for instance, might have significant limitations in social interaction and communication. A child with cerebral palsy might have severe limitations in mobility and motor control.

Medical evidence is crucial. Documentation from doctors, therapists, school records, and treatment history all play a role in showing how the condition affects the child's daily life. The guide explains what kinds of medical records matter and how to organize them for review.

Practical Takeaway: To be found disabled, a child must have a condition that causes marked and severe functional limitations expected to last at least 12 months. Medical documentation showing how the condition affects daily activities is essential.

Income and Resource Limits for SSI

SSI is a needs-based program, which means a family's income and resources matter. Understanding these limits is important for families considering SSI for their child. The limits change each year, and as of 2024, the federal SSI payment amount for an individual is $943 per month, though some states add additional payments.

For SSI purposes, "income" includes earned income (money from work), unearned income (like Social Security payments, pensions, or gifts), and in-kind income (like food or shelter someone else provides). When counting income for a child, Social Security counts the parents' income as well, using what's called "deemed income." Essentially, a portion of the parents' income is treated as if it belongs to the child. The amount deemed depends on whether one or both parents are in the household and whether there are other children also receiving SSI.

The resource limit for SSI is $2,000 per individual as of 2024. Resources include cash, bank accounts, real property (other than the home where the child lives), vehicles, and other items of value. However, not all resources count. The home the family lives in doesn't count. One vehicle used for transportation doesn't count. Certain items like household goods and personal effects have no limit. Life insurance policies under certain amounts don't count.

Income and resource limits can be complicated because of special rules. For example, the first $65 of monthly earned income plus half of the remaining earned income is not counted. Certain gifts to a child, educational savings accounts, and other income may have special treatment. Families may exceed the income or resource limit and still receive SSI if they fall within what Social Security calls the "threshold" of eligibility, which involves complex calculations.

The guide provides examples of how income is counted and explains the resource rules in clearer language. It also describes some programs that help people save money without losing SSI benefits, such as ABLE accounts and Special Needs Trusts.

Practical Takeaway: SSI has income and resource limits. Understanding what counts toward these limits—and what doesn't—helps families determine whether a child might be within the program's boundaries.

The Process of Submitting Information to Social Security

When a family wants Social Security to review a child's situation for SSDI or SSI, they need to submit information and medical records. This process involves gathering documents and providing details about the child's condition and the family's circumstances.

For SSDI based on a parent's record, the child needs a Social Security number and proof of relationship to the worker. For SSI, the child needs a Social Security number as well, and the family provides information about income and resources. In both cases, medical records are essential. These should include reports from doctors, psychiatrists, neurologists, therapists, or other medical professionals who have treated the child. School records, including reports from special education teachers and school psychologists, are also helpful because they show how the condition affects the child's learning and functioning in school.

Social Security requests specific forms. For SSDI, families typically complete Form SS-5 (Application for a Social Security Card) if the child doesn't have a number, and Form SSA-1-BK (Application for Benefits). For SSI, families complete Form SSA-8000-BK (Supplemental Security Income (SSI) Application). These forms ask for personal information, medical history, and details about living arrangements and finances.

Families can submit information in several ways. They can visit a local Social Security office in person, mail completed forms and documents to Social Security, or use a My Social Security account online to submit some information. Many families work with a representative—either a lawyer or a non-lawyer advocate—who helps organize the information and communicate with Social Security.

After information is submitted, Social Security reviews it. They may request additional medical records, ask for clarification, or schedule a medical examination with a doctor chosen by Social Security. The review process can take several months. Social Security sends a decision letter explaining whether benefits were approved or denied and why.

The guide walks through each step of this process, explaining what to expect and how to gather and organize documents efficiently.

Practical Takeaway: Submitting to Social Security requires medical records, school records, and completed forms. Starting with organized documentation makes the process clearer and more manageable.
