Home Accessibility Tax Credit (HATC) for Ottawa Homeowners: How to Claim Up to $20,000 on a Walk-In Tub

By Curtis McGrath, Project Coordinator | 18 years renovation experience | Bytown Better Bathtubs and Showers | Updated July 2026

If you are helping a parent stay in their home, or planning ahead for yourself, the home accessibility tax credit is one of the few federal programs that directly offsets the cost of a safer bathroom. It comes up often at our in-home consultations across Ottawa, Nepean, Orleans, Kanata, and Barrhaven, usually with the same misunderstanding attached: people hear “$20,000” and assume that is money coming back to them.

It is not. It is worth understanding properly before you budget around it, because the difference between the expense ceiling and the actual benefit is roughly $17,000. This guide explains what the credit really pays, why a walk-in tub qualifies, and exactly what the Canada Revenue Agency expects you to keep on file.

What the Home Accessibility Tax Credit Actually Pays

The home accessibility tax credit is a non-refundable federal credit. A qualifying individual can claim up to $20,000 per year in eligible expenses for an eligible dwelling. If more than one qualifying individual lives in the same dwelling, the total eligible expenses for that dwelling still cannot exceed $20,000.

The credit itself is 15 percent of those expenses. The arithmetic is worth seeing in a table, because it is where most of the confusion lives.

Because the credit is non-refundable, it reduces the tax you owe rather than creating a refund on its own. A retiree with little or no tax payable may not see the full benefit, which is a conversation worth having with an accountant before the work is booked.

Why a Walk-In Tub Qualifies

A walk-in tub is a brand new therapeutic bathtub with a watertight door. You step in through the door rather than lifting a leg over a high wall, and the tub sits higher, closer to the feel of a jacuzzi. It is not a modification of your existing tub. It is a complete unit that is plumbed in and built into the bathroom.

That permanence is exactly what the Canada Revenue Agency looks for. A qualifying renovation must be enduring in nature and integral to the dwelling, and it must either help the qualifying individual gain access and mobility within the home, or reduce their risk of harm. A tub you can step into instead of climbing into does both.

The exclusions are just as instructive. Amounts paid to acquire property that can be used independently of the renovation are not eligible, and an item that will not become a permanent part of the dwelling generally does not qualify. That rules out portable bath lifts, freestanding stools, and anything you could carry out of the house. It also means the professional installation is not an optional extra. It is the part that makes the claim stand up.

Our walk-in tub installations are plumbed in, sealed, and built into the room, and every job comes with an itemized invoice. If you are still deciding between a tub and a low-threshold shower, our shower installation page compares the two approaches.

Who Qualifies for the Credit

There are two ways to be a qualifying individual. The first is age: someone who is 65 years of age or older at the end of the tax year. The second is disability: someone eligible for the disability tax credit at any time during the year, regardless of age.

You do not have to be the qualifying individual to make the claim. An eligible individual, such as a spouse or common-law partner, or a parent, grandparent, child, grandchild, sibling, aunt, uncle, niece, or nephew, may claim on behalf of the qualifying individual in certain circumstances. Families supporting an aging parent in Ottawa use this regularly.

The dwelling must be located in Canada and be ordinarily inhabited by the qualifying individual, and owned by them, their spouse, or in some cases the eligible individual making the claim.

The Rule Most Ottawa Homeowners Miss: Grants Do Not Reduce Your Claim

This is the single most valuable and least understood detail. The Canada Revenue Agency states plainly that the home accessibility tax credit is not reduced by government assistance, including grants, forgivable loans, or tax credits from federal, provincial, or territorial governments.

In practice, an Ottawa senior who receives municipal or provincial accessibility funding toward a bathroom modification can still claim their eligible expenses under this credit. The programs stack. If an expense also qualifies as a medical expense, it can be claimed as both a medical expense and a home accessibility expense.

The Canada Revenue Agency maintains the authoritative page on this, and it is worth reading before you file. For general guidance on aging in place and home modification, the Canada Mortgage and Housing Corporation publishes useful material, and Parachute Canada covers fall prevention, which is the underlying reason most of these renovations happen.

What a Walk-In Tub Costs in Ottawa

Pricing determines how much of the $20,000 ceiling you can realistically use. Here is where our services sit in 2026.

Because a walk-in tub on its own sits below the yearly ceiling, many Ottawa homeowners pair it with other accessibility work in the same tax year, such as grab bar reinforcement, a curbless shower from a tub to shower conversion, or wider doorways. Grouping the work is how families make full use of the limit. For a broader view of what a bathroom project costs here, see our bathroom remodeling cost in Ottawa guide.

How to Claim It, Step by Step

The mechanics are straightforward once the work is done properly.

1. Confirm the person qualifies

Age 65 or older at the end of the tax year, or eligible for the disability tax credit at any time during the year.

2. Have the work done in the tax year you are claiming

The expenses must be for work performed and goods acquired within that same tax year. A tub installed in January 2027 does not belong on a 2026 return.

3. Get an itemized invoice

This is where the claim is won or lost. The invoice should clearly identify the vendor or contractor, their business address, their GST or HST registration number where applicable, a description of the work done, the address where it was done, and the amount. Keep proof of payment alongside it.

4. Total your eligible expenses

Add together the eligible expenses for the dwelling, up to the $20,000 yearly maximum. If two qualifying individuals live there, the dwelling total still cannot exceed $20,000.

5. File on line 31285

Complete the chart for line 31285 using the Federal Worksheet, then enter the result on line 31285 of your federal return. Do not send the supporting documents with your return. Keep them in case the Canada Revenue Agency asks to see them later.

How Bytown Better Bathtubs and Showers Supports Your Claim

We are a bathroom renovation company, not an accounting firm, and we are careful about that line. What we can do is make sure the renovation itself meets the standard the credit is built around, and that your paperwork is in order.

Every walk-in tub we install is permanently plumbed in and integral to the bathroom. Every job is completed by professionally trained installers. Every quote is written and upfront with no hidden fees, and every completed project comes with a fully itemized invoice listing exactly what was installed, at what address, for what amount. That is the document your accountant will ask for.

Customers occasionally tell our team they plan to claim the credit after their renovation. The filing stays with the homeowner and their accountant, as it should. Our role is to hand you documentation that leaves no ambiguity. You can see the results of that approach in our customer success stories.
