Tax Deductions Family Caregivers Miss

Most families paying for a parent’s care do not think of themselves as having a tax situation. They think of themselves as writing checks. But a considerable amount of what has already been spent may be deductible, and the rules are not obscure. They are simply written for accountants, in a publication nobody reads until somebody tells them to.

This is a map of what to ask about before you file, not tax advice. Thresholds and dollar amounts change, and the details turn on facts about your household that only your own return shows. Confirm anything here with the IRS at irs.gov or with a preparer who has read your situation.

The rule that decides everything: whose expenses can you count

You cannot deduct medical expenses you paid for just anybody. The person has to be your dependent, or would qualify as one except for the income test.

That distinction catches families out constantly, because a parent with modest Social Security income often earns too much to be claimed as a dependent, and the family concludes the door is shut. It is not. For the medical expense deduction specifically, a parent can be a qualifying relative even where the income limit blocks claiming them as a dependent on the rest of your return. The support test still applies: broadly, you need to be providing more than half of their support.

There is also a timing rule worth knowing. You can include expenses for someone who was your dependent either when the service was provided or when you paid the bill. Care given in December and paid in January does not fall down a crack.

What actually counts as a medical expense

This is where families under-claim most heavily, because the category is far wider than doctors and prescriptions.

The one that surprises people: nursing services do not have to be performed by a nurse. The IRS position is that the services need only be of a kind generally performed by a nurse. Help with bathing, dressing, grooming and administering medication for someone who is ill can qualify, whoever is providing it.

That brings a great deal of paid home care into scope. It also brings a condition with it, and the condition is the part people get wrong.

The allocation rule, and why your invoices matter

Where a caregiver does both personal care and household work, the cost has to be split. Only the nursing portion is deductible. The IRS illustrates it plainly: an attendant paid a weekly amount who spends a tenth of the time on household tasks yields a deduction for the remaining nine tenths, and the household share is simply not deductible.

The practical consequence is about record keeping rather than tax law. If your invoices say nothing but a total, you are left estimating a split at filing time with nothing to support it. If they describe what was actually done, the allocation is a calculation instead of a guess.

The same allocation logic follows through to employment taxes. If you employ a caregiver directly and pay Social Security, Medicare, federal unemployment or state employment taxes on their wages, those taxes count as a medical expense to the extent the wages did. Families who hire privately, rather than through an agency, routinely miss this. Our guide to reading a home care service agreement covers the wider difference between employing somebody and engaging an agency.

The threshold that decides whether any of it helps

Medical expenses are deductible only above 7.5% of your adjusted gross income, and only if you itemize rather than take the standard deduction.

Two things follow from that. First, small amounts rarely produce a benefit, so the calculation is worth doing only when care costs have become significant. Second, and more usefully, expenses are counted across everyone on the return. Your own medical costs, your spouse’s and your dependent parent’s are added together against the one threshold. Families who assess the parent’s costs in isolation frequently conclude they fall short when the combined figure clears it comfortably.

The commonest reason a family misses this deduction is not ineligibility. It is that nobody totaled the year up, because the money left in installments too small to feel like a tax matter.

When several children are paying

Here is the situation that defeats most families. Three adult children each contribute toward a parent’s care. None of them individually provides more than half of the parent’s support, so on the face of it none of them can claim the parent, and the deduction evaporates for everyone.

The fix is a multiple support agreement, filed on IRS Form 2120. Where two or more people together provide more than half of somebody’s support but no one person does, they can agree which of them claims the parent for that year. The others sign a declaration that they will not.

Two conditions attach. The person claiming still has to have provided more than a set share themselves, so it cannot be handed to whoever happens to have the best tax position regardless of what they contributed. And medical expenses paid by the other contributors cannot be claimed by anybody, including the designated person, who may only include what they personally paid.

There is a further trap worth flagging: using a multiple support agreement to claim a dependent blocks using that dependent to file as head of household. Where head of household status is worth more than the deduction, the agreement is the wrong move. This is a genuine calculation, not a formality, and it is the point at which paying a preparer for an hour usually pays for itself.

Families who have run a proper family meeting about care tend to sort this out in one conversation. Families who have not tend to discover the issue in April, separately, from three different accountants.

The categories people forget entirely

Travel for medical care. Journeys to appointments are a recognized category, whether by car or otherwise. It requires a log, which is why it is usually claimed by the families who started keeping one in January rather than the ones reconstructing a year in April.

Home modifications for a medical reason. Grab bars, ramps, a walk-in shower and similar changes can be deductible medical expenses, though the treatment depends on whether the work adds value to the property. Where it does, only the excess of the cost over the added value is generally allowable. Keep the invoices either way. Our bathroom guide covers which of these changes actually reduce risk.

Medicare premiums and long-term care insurance premiums. Both can be includable, the latter subject to age-based limits.

Equipment and supplies bought for a medical reason, from a commode to incontinence products, rather than only the items that arrived with a prescription.

Credits, which are not the same thing

Deductions reduce the income you are taxed on. Credits reduce the tax itself, which usually makes them worth more, and there are two worth asking about.

The credit for other dependents may apply to a dependent parent who does not qualify for the child tax credit. And the child and dependent care credit is not only for children: it can extend to care for a spouse or dependent who is incapable of self-care, where the care was necessary so that you could work or look for work. Adult day services and in-home care are the usual candidates.

Both have eligibility conditions and current amounts that change, so treat them as questions for the IRS or your preparer rather than assumptions.

What to do before December

Almost all of this is decided during the year rather than at filing time. Keep every invoice and receipt including mileage. Ask your agency for itemized billing that distinguishes personal care from household support. If several of you are contributing, work out early who is claiming and whether a multiple support agreement is appropriate, because signatures are easier to collect in November than in April.

Then have somebody total it. The families who benefit are not the ones with unusual circumstances. They are the ones who added the year up.
