Are aging-in-place home modifications tax deductible?

They can be. IRS Publication 502 treats home improvements made for medical reasons as a medical expense, to the extent the work does not increase the value of the home. You must itemize, and only the part of your total medical expenses above 7.5% of your adjusted gross income (the floor on 2025 returns) counts.

Is a walk-in shower tax deductible?

It may be, if a doctor recommends it for a medical condition and you itemize. Only the part of the cost that does not add value to your home counts, and your total medical expenses must clear the annual floor.

Is a stair lift tax deductible?

Possibly. A stair lift installed because of a medical condition is the kind of expense Publication 502 describes. Keep the doctor's letter and receipts and ask your tax preparer how to claim it.

What records do I need?

A letter from the doctor or occupational therapist explaining the medical need, itemized contractor invoices and proof of payment, and, for larger projects, an appraisal or written estimate of any value the work added to the home.

Do grab bars count as a medical expense?

Grab bars and railings installed for a medical reason are a common example of a qualifying improvement, and they rarely add home value, so the full cost usually counts toward your medical expenses.

Are Home Modifications Tax Deductible? IRS Publication 502 Rules

Home modifications made for medical reasons can count as a deductible medical expense under IRS Publication 502, but only to the extent the work does not add value to your home, and only if you itemize deductions and your total medical expenses for the year exceed the floor, which is 7.5% of your adjusted gross income on 2025 returns. Many families will not clear that bar. In a year with a large remodel plus other medical costs, some do. Keep the doctor's letter and every receipt, and talk to your tax preparer before you count on it.

The three conditions, in plain English

Publication 502 is the IRS guide to what counts as a medical expense. It treats improvements to a home as medical expenses when the main purpose is medical care for you, your spouse or your dependent. Three conditions decide whether a remodel helps your tax return.

1. The work is for a medical reason. Not comfort, not resale, not "someday". A doctor, occupational therapist or other clinician recommends it because of a diagnosed condition or a documented risk. Get that in a letter dated before the work.

2. Only the part that does not add value counts. If a modification increases the value of your home, you subtract the increase and deduct what is left. If it adds no value, the full cost counts. More on this below.

3. You itemize and clear the floor. Medical expenses are an itemized deduction on Schedule A, so you give up the standard deduction to use them. Then, only the portion of your total medical expenses above the floor is deductible: 7.5% of your adjusted gross income on 2025 returns. Check the current Publication 502 or your tax preparer for the year you file.

"To the extent it does not add value"

This is the part people miss. The IRS reasons that if a remodel raises your home's value, that portion is an investment, not a medical cost. So:

Grab bars and railings, an entrance ramp, a stair lift or widened doorways rarely add resale value. A buyer may even see them as something to remove. The full cost typically counts. Publication 502 says improvements made to accommodate a disability generally do not increase a home's value, and singles out elevators as the exception that usually does.
A full aging-in-place bathroom remodel with new tile, fixtures and a curbless shower may add some value. Only the cost above the value added counts.
A main-floor bedroom and bath addition can add significant value, so a large share may not count.

Publication 502 includes a capital expense worksheet that asks for the value of the home immediately before and immediately after the improvement. For a large project, a written appraisal or an appraiser's letter is the usual way to support those two numbers. For small items that plainly add no value, the full cost goes on the worksheet. Ask your preparer what they want in the file.

Which modifications typically qualify

Publication 502 (2025) lists example improvements made to accommodate a home to a disabled condition. In its words, with the matching upgrade on this site:

Constructing entrance or exit ramps (ramps and entries)
Widening doorways at entrances or exits, and widening or modifying hallways and interior doorways (widened doorways and hallways)
Installing railings, support bars or other modifications to bathrooms, and adding handrails or grab bars anywhere in the home (grab bars and railings)
Modifying stairways, and installing porch lifts and other forms of lifts (stair lifts; elevators, the publication notes, generally add value)
Lowering or modifying kitchen cabinets and equipment
Moving or modifying electrical outlets and fixtures, modifying door hardware, modifying the areas in front of entrance and exit doors, and grading the ground to provide access

Publication 502 does not name showers or tubs. A roll-in shower is a modification to a bathroom, so the same medical-purpose test applies; your preparer makes the call.

A walk-in tub can qualify under the same reasoning if a doctor documents the medical need, but spa features such as jets and heated seats are a harder case, because Publication 502 excludes costs incurred for personal motives, such as architectural or aesthetic reasons, and jets look like comfort rather than care.

Records to keep

Record	Why it matters
Letter from the doctor or occupational therapist, dated before the work	Establishes the medical purpose
The whole-home safety assessment report, if you had one	Ties each modification to a specific risk
Itemized contractor invoices and the signed contract	Shows what was done and what it cost
Proof of payment (bank or card statements, cancelled checks)	Proves you paid it in the tax year
Appraisal or appraiser's letter on value added, for large projects	Supports the "does not add value" calculation
Insurance or grant reimbursement records	You can only deduct what you were not reimbursed for

Publication 502 says to keep records that support the deduction and not to send them with the return. Keep the file for as long as your preparer advises.

If you are paying for a parent's home

Adult children often pay for a remodel in a parent's house. Publication 502 lets you include medical expenses you paid for your spouse, for a dependent, or for a person who would have been your dependent except that they had gross income of $5,200 or more (the 2025 figure), filed a joint return, or could be claimed on someone else's return. When siblings share a parent's support, a multiple support agreement decides which one of them can claim the expenses, and the others cannot. The rules are specific. Do not assume. Bring the facts (who owns the home, who paid, how much support you provide) to your tax preparer before the work starts, because the answer may change how you structure the payment.

Realistic expectations

Many households take the standard deduction and never itemize, so this deduction helps only in a year when your itemized deductions, including medical costs, add up to more than the standard deduction. A year with a remodel, a hospital stay and ongoing care costs is the kind of year where that happens. Treat the deduction as a possible rebate on money you were going to spend anyway, not as a reason to spend it.

The same receipts serve other purposes. A long-term care policy may reimburse part of the work, and a VA grant may cover some of it for a veteran. For most families the job is paid directly, and the deduction is what softens it. For a sense of scale, a full aging-in-place bathroom remodel runs $6,600 to $28,000 nationally with an average near $11,000 (2022 to 2026 estimates; get local quotes), which is the kind of figure that can matter at tax time.

Talk to your tax preparer

This page explains the rule; it is not tax advice for your return. A preparer who knows your income, your other deductions and your state's rules can tell you whether itemizing makes sense and how to document the medical purpose. Ask before the project, not in April.
