ABLE as State Fiscal Policy: The Asset-Test Cliff, the Take-Up Gap, and the January 2026 Age Adjustment Rollout

This brief summarizes preliminary findings from "ABLE Accounts and the Household Economic Response to Asset-Test Relief" (Yin, 2026, RISEI Working Paper, July 2026). All numeric estimates below are illustrative and rounded; the working paper is a draft and specific magnitudes may change in later versions.

Because ABLE relaxes only the asset margin, its behavioral effects are separable from every other program-design lever. This brief walks through what our preliminary state-year evidence indicates about population-level effect sizes, how the take-up gap binds impact, how the Medicaid interaction shapes state fiscal projections, and what state legislators and treasurers should expect from the January 2026 rollout.

The $2,000 Asset Cliff

The Supplemental Security Income resource limit was set at $2,000 by the Family Support Act of 1988. It has not moved since. Inflation has eroded its real value from roughly $5,000 in 1988 dollars to about $1,000 today. In 34 states, Medicaid eligibility for adults with disabilities runs through the SSI rule directly. An adult with a disability whose countable savings reach $2,001 forfeits both the monthly SSI check and Medicaid coverage. The implicit marginal tax on the second-to-last dollar of savings exceeds one million percent.

Illustrative Population-Level Effects

Estimates are averaged across multiple staggered difference-in-differences estimators — two-way fixed effects, Callaway-Sant'Anna, Sun-Abraham, Borusyak-Jaravel-Spiess, and de Chaisemartin-D'Haultfoeuille — and triangulated across three complementary state-year panels. Standard errors are clustered at the state, with wild-cluster bootstrap p-values reported alongside t-based inference given the small number of never-adopter clusters. Details in the working paper.

The Take-Up Gap

The 3 percent take-up rate is the binding constraint on population-level impact. A policy that generates roughly a 1 to 3 percent income lift for adults with disabilities in the states that launched it is generating an aggregate national response scaled by who has an account. The lever, therefore, is trusted-messenger outreach through disability-service agencies, VR counselors, Community Work Incentives Coordinators, and family navigators — not statutory design changes.

Medicaid-Expansion Interaction

Our analysis of the ABLE × ACA Medicaid expansion interaction indicates that the two policies substitute on the disposable-income margin. In states that did not expand Medicaid, our preliminary estimate of the ABLE effect on disposable income is at the higher end of the 1 to 3 percent range. In states that did expand Medicaid, the incremental ABLE effect is close to zero. Medicaid expansion alone appears to raise disposable income of adults with disabilities by roughly 1 percent through a medical-debt-relief channel, consistent with earlier work (Brevoort, Grodzicki, and Hackmann, 2020).

The January 2026 Age Adjustment

The ABLE Age Adjustment Act of 2022 raises the age-of-onset threshold from 26 to 46, effective January 1, 2026. Approximately 6 million additional working-age adults with disabilities become eligible. Because the newly eligible cohort is older, and our preliminary evidence indicates that effects concentrate among younger workers, per-person magnitudes for this cohort will likely be smaller than for the 18-to-25 group. Aggregate response depends on the age distribution of new eligibles, take-up at older ages, and the reach of state outreach.
