Social Security Fairness Act Impact on Idaho Disability Benefits

What the Social Security Fairness Act Changed

The Social Security Fairness Act (H.R. 82), signed into law on January 5, 2025, repealed two provisions that had reduced Social Security benefits for millions of Americans for decades:

• The Windfall Elimination Provision (WEP) reduced retirement benefits for workers who earned pensions from employment not covered by Social Security — such as Idaho teachers under the Public Employee Retirement System of Idaho (PERSI), some firefighters, and police officers under non-Social Security pension plans.
• The Government Pension Offset (GPO) reduced or eliminated spousal and survivor Social Security benefits for individuals receiving government pensions from non-covered employment.

Both provisions are now fully repealed for all benefits payable after December 2023. The SSA completed over 3.1 million automated record adjustments and distributed approximately $17 billion in retroactive lump-sum payments by July 2025.

Why This Matters for Disabled Adults in Idaho

The repeal has a direct and significant impact on Disabled Adult Child (DAC) benefits — the Social Security payments available to adults whose disability began before age 22 when a parent retires, becomes disabled, or dies.

DAC benefits are calculated as a percentage of the parent's Primary Insurance Amount (PIA). Under the old WEP rules, a parent's PIA was reduced if they had non-covered earnings, which directly lowered the DAC payment their disabled adult child could receive. With WEP repealed, the parent's full earnings record is used, and the resulting DAC payment is higher — in some cases by $500 to $1,000+ per month.

For Idaho families, this matters because PERSI — the state pension system covering teachers, state employees, and many municipal workers — includes positions that historically fell under non-covered employment categories. A disabled adult child whose parent retired from an Idaho teaching position may now receive a substantially higher DAC benefit than they would have under the old formula.

The Medicaid Protection Problem

Higher DAC payments are financially positive, but they create an immediate administrative risk. When DAC benefits replace SSI as the primary income source, the SSI payment drops to zero. In Idaho, SSI eligibility does not automatically enroll or maintain Medicaid, so DHW may need to make a separate Medicaid determination.

This is where IDAPA 16.03.05.806 becomes essential. Under this Idaho administrative rule, DHW must disregard the entire DAC benefit amount when determining Medicaid eligibility, provided the individual received SSI or AABD cash based on blindness or a disability that began before age 22 and became ineligible for and remains ineligible for AABD cash or SSI solely because the disabled adult child's RSDI benefit started or increased on or after July 1, 1987. The protection extends to all subsequent COLA increases on the DAC benefit.

Before the Fairness Act, many families never encountered this trap because WEP-reduced DAC benefits were sometimes small enough that SSI continued at a reduced level, so the DAC increase did not require the same Medicaid-protection review. Now, with full PIA calculations, more families will see DAC benefits that fully offset SSI — making the IDAPA protection a critical step that was previously unnecessary for their situation.

Retroactive Payments and the Resource Limit

The SSA's retroactive lump-sum payments create a separate risk. If a disabled adult received a retroactive adjustment for months of underpaid DAC benefits, the payment can eventually affect the SSI resource test. The SSI resource limit is $2,000; identifiable, unspent Title II retroactive payments are excluded for nine months after receipt, but remaining funds after that period could push the individual over the limit and require a separate Medicaid review.

SSA excludes identifiable, unspent Title II or Title XVI retroactive payments from resources for nine months following the month of receipt, but families need to act before that period ends. Two options:

• ABLE account: Transfer funds into an Idaho STABLE account, which excludes up to $100,000 from the SSI resource test. Annual contribution limit is $20,000.
• Special needs trust: For larger amounts, deposit into an existing first-party or third-party special needs trust. The trust assets are excluded from countable resources if properly structured.

What Families Should Do Now

If your family includes a disabled adult whose parent worked in non-covered public employment in Idaho:

1. Check whether the SSA has already adjusted the parent's record. Most adjustments were completed by mid-2025, but some cases required manual review. Call the SSA at 1-800-772-1213 or visit the local field office if no adjustment has been received.
2. If the adult child is not yet receiving DAC benefits, file an application. With the WEP/GPO repeal, DAC benefits that would have been minimal or zero under the old rules may now be substantial.
3. Before any DAC benefit starts, prepare the IDAPA 16.03.05.806 protection letter for DHW. Do not wait for the Medicaid termination notice — file the protection proactively as soon as the DAC award letter arrives.
4. If a retroactive lump sum arrives, transfer excess funds into an ABLE account or special needs trust within the exclusion period to avoid an SSI resource suspension.
