DAC Benefits Washington — Disabled Adult Child Social Security Benefits Explained

What DAC Benefits Are

Disabled Adult Child benefits — sometimes called "childhood disability benefits" or CDB — are Title II Social Security payments made to an adult child with a disability based on a parent's earnings record. When a parent retires, becomes disabled, or passes away, their qualifying adult child can receive a monthly check drawn from the parent's Social Security account.

The payment amount is typically 50% of the parent's Primary Insurance Amount if the parent is living, or 75% if the parent has died, subject to family maximum rules. For many families, this means a significantly larger monthly payment than SSI alone.

Who Qualifies

Four requirements, all of which must be met:

1. Age 18 or older at the time of the claim
2. Unmarried (marriage generally terminates DAC eligibility, with narrow exceptions for marriages to other DAC recipients)
3. Medically disabled under SSA's adult standard — the same standard used for the age-18 SSI redetermination
4. Disability onset before age 22 — the impairment must have begun before the individual's 22nd birthday, though the claim can be filed at any age

The parent must be receiving Social Security retirement or disability benefits, or must have died with sufficient work credits. The adult child does not need their own work history — the benefit is based entirely on the parent's record.

How DAC Interacts with SSI

Here's where it gets complicated. DAC payments are classified as unearned income for SSI purposes. If the monthly DAC amount is less than $1,014 (the 2026 SSI federal benefit rate of $994 plus the $20 general income exclusion), the individual receives both benefits concurrently — SSI tops up the difference so total monthly cash income equals the federal standard.

If the monthly DAC amount reaches $1,014 or more, the SSI cash payment is reduced to zero. The DAC payment replaces the federal SSI cash payment. This is usually a net financial gain — a DAC check of $1,200 is better than $994 in SSI — but it creates a Medicaid problem.

The Medicaid Protection You Can't Afford to Miss

When SSI stops because of DAC income, the automatic Section 1634 Medicaid pathway may no longer protect coverage. But federal law (42 U.S.C. § 1396a(a)(50)) includes a specific safeguard: Washington State must completely disregard the DAC income when calculating Medicaid eligibility. The individual is treated as if they're still receiving SSI for Medicaid purposes.

This means Categorically Needy Apple Health — the same full-benefit, zero-premium coverage — continues after SSI ends. The protection applies for as long as the individual would be SSI-eligible if the DAC income were removed from the calculation.

In practice, this protection should engage automatically through the Health Care Authority's electronic systems. In practice, it sometimes doesn't. Families should verify the Medicaid case status after DAC payments begin and confirm that the coverage category is listed as DAC-protected rather than showing a pending termination.

When a Parent Dies

A parent's death can trigger DAC eligibility. The surviving adult child files with the local SSA office using evidence of the parent's death, their own disability documentation, and proof that the disability began before age 22.

If the adult child is already receiving SSI, the family still needs to coordinate the DAC claim with SSA. Once DAC payments begin, SSA adjusts (or terminates) SSI. The critical action is verifying that Medicaid protection engages at the same time.

If the adult child is not currently receiving any benefits, the family should contact SSA about filing the DAC claim and provide evidence that the disability began before age 22.

WEP and GPO Are Repealed

The Social Security Fairness Act, signed January 5, 2025, repealed the Government Pension Offset and Windfall Elimination Provision for benefits payable January 2024 onward. Families with a parent who worked in non-covered public employment, including public-school, fire, or municipal work, should verify with SSA that any adjustment and retroactive pay back to January 2024 was applied. People who never applied because of WEP/GPO must file a new claim; that step is not automatic.

Planning Ahead

DAC eligibility depends on documenting disability onset before age 22. Families should preserve all medical and educational records from childhood and adolescence — these become the evidentiary backbone of a DAC claim that may not be filed for decades.
