Moving a parent or spouse into assisted living can easily cost several thousand dollars a month, and families often assume none of it is deductible because it looks more like housing than medical care. That is not always true. The IRS allows a meaningful portion of assisted-living costs to count as a deductible medical expense, but only when a resident meets a specific definition of chronic illness and the facility’s care follows a documented plan. Understanding that distinction can be the difference between missing a real deduction and claiming one correctly.
The “Chronically Ill” Standard That Unlocks the Deduction
Not every assisted-living resident automatically qualifies for the medical-expense deduction, even if they are paying substantial fees for care. According to IRS Publication 502, Medical and Dental Expenses, a resident must be certified as chronically ill by a licensed health care practitioner, based on an evaluation within the prior 12 months, before personal-care costs become deductible medical expenses. That certification requires one of two things to be true: either the person is unable to perform at least two activities of daily living, such as eating, bathing, dressing, toileting, transferring, or maintaining continence, without substantial assistance for a period expected to last at least 90 days, or the person requires substantial supervision to be protected from health and safety threats due to severe cognitive impairment, such as advanced dementia.
A resident who moves into assisted living primarily for convenience, social engagement, or general aging-related support, without meeting either of those thresholds, generally does not qualify for the medical-expense deduction on their personal-care costs, even though the facility bill may look similar to one for a resident who does qualify.

Assisted Living Versus a Nursing Home: A Different Test
That certification threshold is unique to assisted living, in-home care, and other personal-care settings, not to every type of long-term care. IRS Publication 502 treats a stay in a nursing home or similar institution differently: the cost of medical care, meals, and lodging there is deductible whenever the principal reason for being in the facility is to receive medical care, without requiring the same chronically-ill certification or written plan of care that assisted living residents need. A family paying nursing-home-level costs generally has an easier deduction to document than one paying for assisted living, largely because assisted-living facilities serve a wider range of residents, from those who are essentially independent to those who meet the chronic-illness threshold, while a nursing home’s population skews more uniformly toward residents who need medical care as the primary reason for being there.
What Counts, and What Requires a Plan of Care
Once a resident is certified chronically ill, the IRS treats “maintenance or personal care services” — help with the activities of daily living listed above, or supervision related to cognitive impairment — as deductible medical care, but only when those services are provided under a plan of care prescribed by a licensed health care practitioner. That plan does not need to be elaborate, but it should specify the services the resident requires and be updated periodically, since it is the documentation that ties the facility’s personal-care charges to a genuine medical need rather than ordinary room and board.
In practice, this often means an assisted-living facility’s monthly bill can be split into two categories: the medical or personal-care component tied to the resident’s certified condition and plan of care, which is deductible, and the portion covering standard housing, meals, and amenities that any resident would pay regardless of health status, which generally is not. Facilities experienced with long-term care residents will often provide an itemized statement breaking out the medical portion specifically for tax purposes, which families should request rather than trying to estimate the split themselves.
The 7.5 Percent Floor Still Applies
Qualifying assisted-living costs do not simply come off the top of a tax bill. They fall under the same rules as other medical expenses: they are deductible only if the taxpayer itemizes deductions, and only the amount of total unreimbursed medical expenses exceeding 7.5% of adjusted gross income is deductible. For families paying a significant assisted-living bill, that threshold is often cleared easily, since facility costs alone can run well into five figures annually. For a taxpayer whose only medical expenses are the assisted-living costs, comparing the total itemized deduction against the standard deduction is still worth doing before assuming itemizing is the better route.
A related deduction is easy to miss. Premiums paid for a qualified long-term care insurance policy are also deductible medical expenses, but only up to an age-based dollar cap the IRS adjusts each year; for 2025 returns, the limit ranges from $480 for someone 40 or younger up to $6,020 for anyone 71 or older, with amounts paid above the cap not deductible even though the policy itself may be legitimate and in force. Because the cap is tied to the age of the person covered rather than the person claiming the deduction, a taxpayer paying premiums on a parent’s long-term care policy uses the parent’s age, not their own, to determine the limit that applies.
Who Should Be Claiming This
The deduction is not limited to the resident’s own tax return. A family member who pays a parent’s or spouse’s assisted-living costs and who claims that person as a dependent, or who otherwise meets the support test, may be able to claim the qualifying medical expenses on their own return, subject to the same certification and plan-of-care requirements. Because the rules hinge on documentation — the chronic-illness certification, the written plan of care, and an itemized bill separating medical from non-medical charges — families should gather that paperwork from the facility and the certifying physician well before tax season, rather than trying to reconstruct it after the fact.
