529 vs ABLE — the key difference for special-needs families
A 529 plan is a state-sponsored, tax-advantaged college savings account. Contributions grow tax-free and qualified withdrawals (tuition, fees, books, room and board, K-12 tuition up to $10,000/year) are tax-free. Contribution limits are very high (typically $300,000-$550,000 lifetime per beneficiary) and you can superfund up to 5 years of gift exclusion at once ($95,000 in 2027 per donor).
An ABLE (Achieving a Better Life Experience) account is also tax-advantaged but designed for individuals with disabilities that began before age 26 (the ABLE Age Adjustment Act raises this to age 46 effective 2026). Contributions grow tax-free and withdrawals for qualified disability expenses (housing, transportation, healthcare, assistive technology, employment training) are tax-free. The annual contribution limit in 2027 is approximately $19,000 (gift exclusion), with additional ABLE-to-Work contributions for employed beneficiaries (up to ~$15,650 from earned income, bringing the total to ~$34,650).
The SSI and Medicaid asset-test advantage
The killer feature of ABLE accounts: the first $100,000 is excluded from the SSI $2,000 asset cap. Without an ABLE, a disabled beneficiary on SSI cannot save more than $2,000 without losing benefits — making meaningful saving impossible. With ABLE, they can build $100,000 of cushion while keeping monthly SSI. Above $100,000, SSI is suspended (not terminated) until the balance drops back below. Medicaid eligibility is unaffected by ABLE balances at any level.
529 plans do NOT receive this asset-test exclusion. A 529 owned by the beneficiary counts as a student asset on FAFSA (5.64% expected contribution) and counts toward state Medicaid asset tests at full value. For special-needs beneficiaries planning to receive SSI/Medicaid long-term, ABLE is the only viable savings vehicle for cash above $2,000.
When to use each — and when to use both
Use a 529 alone when the beneficiary will not need SSI/Medicaid (e.g., a typically-developing child). The higher contribution ceiling and state tax deduction (NY $5,000, IL $10,000, MI $10,000) make 529 the right vehicle.
Use an ABLE alone when the beneficiary has a qualifying disability before age 26 (or 46 from 2026), receives or expects SSI/Medicaid, and is not planning college. The $19k/year limit is enough for ongoing living-expense savings.
Use both when there's any chance the beneficiary could attend college or vocational training. Front-load the 529 (higher limits, state deduction), then roll 529 funds into the ABLE up to $19k/year as disability expenses arise. The 529-to-ABLE rollover is federally tax-free for the same beneficiary or a family member.
How to use this calculator
Enter your initial deposit, planned annual contribution (capped at $19k for ABLE in 2027), years to grow, expected return, and your state's 529 income-tax deduction percentage. The calculator projects future value for both account types and computes the annual state tax savings from a 529 deduction.
The recommendation engine picks the better account based on your stated use of funds. If "disability living expenses" is the primary purpose, ABLE wins because of the SSI asset-test exclusion. If "higher education" is the primary purpose, 529 wins because of higher contribution limits and state deduction. For "both", the tool suggests opening both and using the 529-to-ABLE rollover as needed.
