Wyoming Optional State Supplement for SSI Recipients

What the State Supplement Is

Wyoming is one of the states that adds a small cash supplement on top of the federal SSI payment. The Wyoming Department of Family Services (DFS) administers the Optional State Supplement (OSS) for aged, blind, and disabled individuals who meet narrow qualifying conditions.

The supplement is modest — historically around $20 per month for an individual — but it arrives automatically. Wyoming uses computerized data files transmitted from the Social Security Administration to identify qualifying recipients, so there is no separate application to file.

Who Qualifies

The qualifying rules are strict. The supplement is available only to SSI recipients who meet all of these conditions:

• SSI is their sole source of income. The moment the recipient has any other countable income — earned wages, unearned benefits like DAC, a pension — the state supplement drops to zero before any other benefit is reduced.
• They live in an independent living arrangement (Living Arrangement Code A) or in the household of another person (Code B). Recipients in institutional settings, group homes, or other living situations do not qualify.
• They are aged, blind, or disabled under the SSA's definitions — which includes adult SSI recipients with intellectual and developmental disabilities.

Why the Supplement Disappears

This is the detail that confuses families: the state supplement is the first benefit to be reduced when other income enters the picture. If a young adult on SSI starts receiving Disabled Adult Child (DAC) benefits when a parent retires, the DAC payment counts as unearned income. After applying the $20 general income exclusion, DAC reduces the SSI check dollar-for-dollar. But the state supplement was already eliminated the moment DAC appeared — because SSI is no longer the person's sole income source.

The practical impact is small in dollar terms, but families should know that the $20 supplement will vanish as soon as their adult child receives any other countable income from employment, DAC, SSDI, or any other source. It returns only if all other income stops and SSI becomes the sole benefit again.

How It Interacts With Other Wyoming Programs

The state supplement does not affect eligibility for the Supports Waiver, Comprehensive Waiver, or the Employed Individuals with Disabilities (EID) Medicaid program. Those programs have their own income standards (the 300% FBR limit of $2,982 per month for waiver eligibility, with EID exempting all earned income).

The supplement also does not affect WYABLE account contributions or SSI's $2,000 resource limit. It is simply a small addition to the monthly cash benefit that appears on the same payment as the federal SSI check.

What to Do About It

There is no action required to receive the supplement — DFS handles it automatically through the SSA data feed. Families should be aware of it primarily to understand why the check amount changes when other income starts or stops. If a young adult's SSI check drops by more than expected when DAC benefits begin, the missing $20 is the state supplement, not an SSA error.
