People with Williams Syndrome in South Dakota may qualify for federal disability benefits like SSI and SSDI, plus state-specific Medicaid waivers and work incentives. This guide explains eligibility, how to apply, and what support is available.
To qualify for Social Security Disability Insurance (SSDI), you must have a medical condition that prevents you from working for at least 12 months and have enough work credits from recent employment. For Supplemental Security Income (SSI), you must meet SSA’s disability criteria and have limited income and resources. Both programs require that your disability stops you from doing substantial work, defined by the Substantial Gainful Activity (SGA) limit. In 2025, the SGA limit is $1,620 per month for disabled individuals and $2,700 for blind individuals. If your countable earnings are above these amounts, you may not qualify for SSDI or SSI benefits [1].
SSDI is based on your work history and Social Security taxes paid. SSI is based on financial need and is available to those with limited income and resources, regardless of work history [2].
In South Dakota, individuals with Williams Syndrome may qualify for Medicaid waivers that provide home and community-based services (HCBS). These waivers help people with disabilities live independently and access needed supports. The state also offers the Medicaid for Workers with Disabilities program, which allows people with significant disabilities to work while keeping Medicaid coverage. Eligibility for these programs depends on your disability, income, and resources. South Dakota follows federal SGA limits for work incentives, but some state-specific thresholds may apply for Medicaid continuation when working [3].
If you receive SSI, you may be automatically eligible for Medicaid in South Dakota. If you receive SSDI, you may qualify for Medicare after a 24-month waiting period, except for certain conditions like ALS [4].
ABLE accounts allow people with disabilities to save money for disability-related expenses without losing SSI or Medicaid benefits. In South Dakota, you can open an ABLE account through the state’s ABLE program. Contributions are tax-free, and funds can be used for qualified expenses like education, housing, and transportation [12].
In 2025, the SGA limit for disabled individuals is $1,620 per month, and for blind individuals, it is $2,700 per month. If your countable earnings are above these amounts, you may not qualify for SSDI or SSI benefits. For SSI, there are also limits on countable income and resources, which vary by state [13].
It is important to report any changes in income, health, or living arrangements to SSA and state agencies to avoid overpayments. Overpayments can result in repayment demands and loss of benefits. Reporting changes promptly helps ensure you receive the correct amount of benefits [14].
