The ABLE age expansion has been in effect since January 1, 2026. Since that date, an estimated 6 million more Americans have become potentially eligible to open these tax-advantaged accounts: people who meet ABLE's disability requirements and whose disability began before age 46, up from the previous threshold of 26.
That is a big deal. ABLE accounts let people with disabilities save up to $20,000 a year (the 2026 limit) without jeopardizing their SSI or Medicaid benefits. The money grows tax-free and can be spent on nearly anything disability-related: housing, transportation, education, therapy, technology, even groceries.
But eligibility is only the first step. The rules have enough nuance that well-meaning families routinely make mistakes with ABLE accounts that leave money on the table or trigger benefit problems they did not see coming.
Here are seven mistakes I see families make with ABLE accounts, and how to avoid each one.
1. Thinking ABLE Replaces a Special Needs Trust
This is the most common misconception I encounter. A family learns about ABLE accounts and assumes they can skip the trust entirely. It is an understandable instinct. ABLE accounts are generally inexpensive and easy to open, and the account holder controls the funds directly. A special needs trust costs thousands to set up, requires a trustee, and is far more complex.
But ABLE accounts have a $20,000 annual contribution cap and state-specific lifetime balance limits (typically $300,000 to $500,000). A special needs trust has no contribution ceiling and no balance cap.
There is also the Medicaid payback issue. When an ABLE account holder dies, the state may file a claim against remaining funds for Medicaid services provided after the account was opened. Properly drafted third-party special needs trusts generally have no Medicaid payback requirement.
Many families, particularly those planning for inheritances, life insurance proceeds, or other substantial assets, benefit from having both. The ABLE account handles day-to-day spending and provides the housing advantage (more on that in a moment). The trust holds larger sums, such as lawsuit settlements, inheritances, and life insurance proceeds, and serves as the long-term estate planning vehicle.
Think of it this way: the ABLE account is the checking account. The trust is the vault.
We break down the full comparison in ABLE Account vs. Special Needs Trust.
2. Missing the Housing Timing Rule
ABLE accounts have a powerful advantage over special needs trusts when it comes to housing expenses. When an ABLE account pays for rent, mortgage, utilities, or other shelter costs, those payments are not counted as in-kind support and maintenance (ISM) for SSI purposes.
That matters. When a special needs trust pays for housing, SSA counts it as ISM and can reduce the SSI benefit by up to $351 per month in 2026. Over a year, that is more than $4,200 in lost benefits.
But the ABLE housing advantage has a timing rule that catches families off guard: funds withdrawn for housing must be spent in the same calendar month they are withdrawn.
Here is where the mistake happens. Say a family withdraws $1,500 from the ABLE account on January 28 to pay February rent. If that money sits in a checking account on February 1 without having been spent, it becomes a countable resource for that month. For someone on SSI with a $2,000 resource limit, that can push them over the threshold.
The fix is straightforward: withdraw and pay in the same month. Set up the withdrawal to hit early enough that the payment clears before month-end.
3. Ignoring the ABLE-to-Work Bonus
The ABLE-to-Work provision lets employed account holders contribute beyond the standard $20,000 annual limit. The eligibility test turns on retirement plan contributions, not just participation: the additional contribution may be available when no contribution is made for the beneficiary that year to an applicable employer retirement plan (a defined contribution plan such as a 401(k), a 403(b), or a 457(b)). The additional amount is limited to the lesser of the beneficiary's compensation or $15,650 for a continental U.S. resident in 2026.
That means an eligible working individual could contribute up to $35,650 in a single year.
The ABLE-to-Work provision was originally set to expire at the end of 2025. The One Big Beautiful Bill Act, signed July 4, 2025, made it permanent. This is no longer a temporary planning window. It is a lasting benefit.
Yet I regularly talk with families who have no idea this provision exists. If your family member with a disability works, even part-time, even modestly, and no contribution is going into an applicable employer retirement plan for them that year, check whether the ABLE-to-Work addition applies. The extra savings capacity is substantial.
4. Not Planning for the $100,000 SSI Threshold
The first $100,000 in an ABLE account is excluded from SSI's resource calculation. That is one of the account's core protections.
Here is how the threshold actually works, because it is widely misunderstood. Once the balance exceeds $100,000, only the excess is counted as a resource. SSI cash benefits are suspended if that excess, combined with the beneficiary's other countable resources, pushes total resources above the applicable SSI limit ($2,000 for an individual).
When that happens, it is a suspension, not a termination. Benefits resume when countable resources fall back below the limit, without a new application. And when the suspension is caused by excess ABLE funds and the person remains otherwise eligible, Medicaid generally continues in states where Medicaid eligibility is linked to SSI.
The mistake is not that families accumulate $100,000 in the account. The mistake is that they do it without a plan. A sudden SSI suspension can disrupt cash flow and housing stability if the family is not prepared.
If the account balance is approaching $100,000, there are options to consider. One is timing larger qualified disability expenses before the threshold is crossed. Another is directing new gifts, inheritances, or contributions to the family's special needs trust instead of the ABLE account, and using trust distributions for larger expenses while keeping the ABLE balance below the line.
The key is anticipating the threshold, not being surprised by it.
5. Forgetting to Name a Successor Beneficiary
When an ABLE account holder dies, remaining funds do not automatically pass to family. Without a designated successor, the balance goes to the account holder's estate. That means probate, and in most states it means the Medicaid program can file a payback claim against those funds for services provided after the account was opened.
Naming a successor is usually a simple form on the ABLE program's website, but families often skip it during enrollment and never circle back.
Know the limits of the designation, though. Where the program permits one, the successor generally must be an ABLE-eligible sibling, half-sibling, or stepsibling. A valid designation can keep any remaining balance out of the beneficiary's probate estate, but outstanding qualified disability expenses and applicable Medicaid claims may still be paid before the transfer. If the goal is broader estate planning, coordinating the ABLE designation with the family's trust and will is essential.
One note for Florida families: Florida eliminated Medicaid recovery claims on ABLE accounts in 2019, which reduces the urgency of the payback concern here. But a successor designation still keeps remaining funds out of probate, which is reason enough to complete the form.
6. Overlooking the 529-to-ABLE Rollover
Families with unused 529 education savings can roll those funds into an ABLE account tax-free. This is especially relevant for families whose child with a disability did not use their full 529 balance for education, or where a sibling's 529 has excess funds.
The rollover counts against the $20,000 annual ABLE contribution limit, so it does not provide additional capacity above the cap. But it does let families reposition money that was saved for one purpose into a more flexible vehicle.
This provision was also made permanent by the One Big Beautiful Bill Act. Previously, it was set to expire at the end of 2025. Families can now plan around this rollover with confidence that it will remain available.
The most common version of this mistake: families simply do not know the rollover exists. If you have 529 accounts and a family member who is ABLE-eligible, it is worth evaluating whether a partial or full rollover makes sense.

7. Defaulting to Your Home State Plan Without Comparing
There are ABLE programs in nearly every state, and 31 of them accept out-of-state residents. You are not limited to your home state's plan.
Some families default to their state program without comparing fees, investment options, or features. The differences can be meaningful. Some plans offer debit or prepaid cards for easy qualified expense spending. Some have lower management fees. Some provide better investment menu options.
For Florida residents specifically, there is no state income tax advantage to staying in-state, since Florida has no state income tax. ABLE United (Florida's program) is solid: no enrollment fee, no account-maintenance fee, and an optional prepaid spending card. But it is worth comparing against programs like Ohio's STABLE, CalABLE, or Virginia's ABLEnow to see which best fits your family's needs.
The ABLE National Resource Center (ablenrc.org) offers a state-by-state comparison tool that makes this process straightforward.
What to Do Next
If your family has an ABLE account or is considering one, here is a short checklist:
Review your current ABLE setup against these seven mistakes. The housing timing rule and successor beneficiary designation are the two most commonly overlooked items.
Check whether the ABLE-to-Work provision applies. If your family member works and no contribution is going into an applicable employer retirement plan for them, this could add up to $15,650 of annual contribution capacity in 2026.
Coordinate with your special needs trust, if you have one. The ABLE account and the trust serve different purposes, and the planning works best when they are aligned.
If you have 529 accounts with unused balances, evaluate whether a rollover makes sense.
Finally, compare your current ABLE plan against other state programs, especially if you enrolled years ago and have not revisited the decision.
