How ABLE accounts work

An ABLE account is a federally authorized savings and investment account for people whose disability began early in life. A childhood autism diagnosis meets the age-of-onset requirement; eligibility comes through SSI/SSDI or a physician's disability certification, self-certified at enrollment. Earnings grow tax-free, qualified withdrawals are tax-free, and the balance stays off the books for means-tested benefits. One account per person; anyone can contribute. Full background in our complete ABLE accounts guide.

What you can pay for

Anything supporting health, independence, or quality of life: uncovered therapy costs, AAC devices and assistive technology, education and tutoring, housing and rent, transportation, sensory equipment, personal support services, respite care, and legal or financial fees. ABLE funds can pay housing without the SSI reductions that normally follow housing help. Keep receipts; non-qualified withdrawals cost tax plus a 10% penalty on earnings.

Mississippi taxes

Mississippi's 529 deductions are their own statutes; confirm with your tax preparer whether any deduction currently applies to Mississippi ABLE contributions. The reliable benefits are federal: tax-free compounding, tax-free qualified withdrawals, and potential Saver's Credit eligibility for a working adult account owner. As a National ABLE Alliance member, Mississippi ABLE offers the same low-cost lineup used by nearly 20 states, including an FDIC-insured checking option with a debit card.

How to open an account

1. Enroll online at msable.com with your child's Social Security number
2. Self-certify eligibility (SSI/SSDI or physician certification, onset before age 46)
3. Make the minimum opening deposit and choose investments
4. Set up automatic monthly contributions

Parents and guardians can open and manage the account for a minor or an adult child who needs support.

Protecting SSI and Medicaid

Up to $100,000 is fully disregarded for SSI; above that, SSI is suspended — not terminated — until the balance falls back below the line. Mississippi Medicaid, including waiver services, is unaffected at any balance.

FAQ

ABLE account or special needs trust? Usually both — the ABLE account for day-to-day disability spending including housing, a trust for large assets. The trust can distribute into the ABLE account.

Can we roll over a MACS 529? Yes, 529-to-ABLE rollovers are permanently allowed within the annual limit.
