Which Part of Assisted Living Is Tax Deductible? The Medical vs. Custodial Split Explained
A family pays $72,000 a year for a parent’s assisted living and assumes the whole bill is a medical deduction. It usually isn’t. Whether you can deduct all of it, part of it, or none of it turns on one question the IRS cares about: is the care medical, or is it custodial? Get that classification right and the deductible portion can range from the full bill down to almost nothing. This post walks the actual split — what counts, what doesn’t, and how to find your number on the facility’s year-end statement.
The rule that determines everything: medical vs. custodial
Assisted living costs are deductible as medical expenses only to the extent the care is medical in nature, and only above the 7.5% AGI floor if you itemize (per IRS Publication 502). The IRS draws a hard line between two kinds of care:
- Medical care — skilled nursing, therapy, prescribed treatments, and the qualified long-term-care services a chronically ill resident receives under a plan of care.
- Custodial care — help with bathing, dressing, eating, and the other activities of daily living (ADLs) that make up most of what assisted living actually provides.
Custodial care is the part families assume is deductible and often isn’t. It becomes deductible only when it is provided to a chronically ill individual under a licensed health care practitioner’s plan of care. That single condition is what unlocks — or closes — most of the deduction.
Are you over the “chronically ill” threshold?
The threshold is specific, not a judgment call. A resident is chronically ill if a licensed health care practitioner has certified, within the prior 12 months, that they either:
- cannot perform at least two of six ADLs (bathing, dressing, eating, toileting, transferring, continence) without substantial assistance for a period expected to last at least 90 days, or
- require substantial supervision to be protected from threats to health and safety due to severe cognitive impairment, such as Alzheimer’s or another dementia.
The certification and a written plan of care are what convert custodial assistance into a deductible expense. If your parent qualifies as chronically ill, ask the facility’s nurse or your parent’s physician to document the ADL or cognitive certification and the plan of care, and keep it with your tax records.
Which portion is deductible: three paths
Once you know the resident’s status, the deductible portion falls into one of three patterns.
Path A — Primary reason for residence is medical
If the principal reason your parent is in the facility is to receive medical care — the case for many skilled-care or memory-care placements — then the cost of the care, plus meals and lodging at that facility, is generally deductible in full. Here the room and board ride along with the medical care because medical care is why they are there.
Path B — Chronically ill, but residence is primarily custodial
This is the most common assisted living situation. The resident is certified chronically ill, so the qualified long-term-care services (the ADL assistance under the plan of care) are deductible — but the room, board, and lifestyle charges generally are not, because the primary reason for being there is custodial, not medical. Your deductible amount is the medical-services portion of the bill, not the whole thing.
Path C — Not chronically ill, no medical plan of care
If your parent moved in for convenience, companionship, or general support and is not certified chronically ill, the deductible portion is limited to the specifically medical charges only — a visiting nurse, prescribed treatments, medication management billed as medical. Rent, meals, housekeeping, and personal-care fees are not deductible.
Where to find your actual number
You do not have to estimate the split yourself. Assisted living facilities routinely provide residents a year-end statement breaking out the portion of fees attributable to medical care — ask for it specifically. That statement, plus the chronically-ill certification and plan of care, is your documentation if the deduction is ever questioned.
A parent is certified chronically ill (needs help with 3 ADLs under a plan of care) and pays $72,000 a year. The facility’s statement attributes $30,000 to qualified long-term-care services and $42,000 to room, board, and lifestyle.
If the family’s AGI is $90,000, the 7.5% floor is \(0.075 \times \$90{,}000 = \$6{,}750\).
Deductible medical (assuming this is their only medical expense): \(\$30{,}000 - \$6{,}750 = \$23{,}250\) — and only if total itemized deductions beat the standard deduction.
The $42,000 custodial-residence portion is not deductible here, because the primary reason for residence is custodial. Had this been a Path A medical placement, the full $72,000 (less the floor) could qualify.
The floor mechanics — why those first thousands produce no deduction — are covered in how the 7.5% AGI floor works. The same medical-vs-custodial line governs skilled-nursing facilities, which we cover in is nursing home care tax deductible. And whether claiming any of this beats the standard deduction is the threshold question in itemize or standard deduction.
This article provides general educational information, not individualized tax or financial advice. The deductible portion of assisted living depends on your parent’s certified care status, the facility’s allocation, and your own return — results vary and are not guaranteed. Confirm your specific situation with a licensed CPA or enrolled agent, and rely on IRS Publication 502 and the facility’s medical-expense statement for amounts.
