How HATC and METC cut accessible home design costs in Canada

What to take away

The two credits that cut Canadian renovation costs, side by side

Most homeowners hear about one credit and miss the other. The HATC is narrow and generous per dollar. The METC is broad, covers a long list of medical items, and can include accessibility work in a home. Both are federal credits under the Income Tax Act, and the CRA applies the same rules when it reviews either claim.

Both are non-refundable. They reduce tax owing, so a household with little tax payable may see no benefit that year. That is why caregivers sometimes claim on behalf of the person who needs the work.

A $20,000 renovation that qualifies for the HATC produces a credit of about $3,000 at the 15% rate, provided the household has enough tax owing.

The two credits sit inside a larger system. The CRA publishes an index of all deductions, credits and expenses for personal income tax, which is where the HATC and METC forms and guides are listed.

Before you price a renovation, work out which credit fits the work and who will claim it. That decision shapes what you build and what you keep.

Home Accessibility Tax Credit: who can claim and what counts as a qualifying renovation

The HATC exists for one purpose: to offset the cost of making a home more accessible for a person with a disability. It is claimed on line 39800 of Schedule 12.

To claim, the person who benefits must be eligible for the Disability Tax Credit. The Disability Tax Credit is a federal credit for people with a severe and prolonged impairment, and it requires a certified form (T2201) completed by a qualified practitioner.

You can claim the HATC for yourself, for a spouse or common-law partner, or for a dependant. The renovation must be to a home where the qualifying individual lives, and it must be done to help them be more mobile or functional, or to reduce the risk of harm.

The dwelling must be the principal residence of a qualifying individual: someone 65 or older at the end of the tax year, or someone approved for the Disability Tax Credit.

What the credit covers

Eligible expenses include the cost of labour, materials, fixtures, rentals of equipment, building plans, and permits. They also include the cost of a professional assessment to determine what modifications are needed.

The work must be a renovation or alteration, not routine maintenance. Replacing a worn carpet is maintenance. Installing a slip-resistant floor as part of an accessibility upgrade can be a qualifying alteration.

Common qualifying items include:

Each qualifying individual has a $20,000 limit per year, and the credit is 15% of eligible expenses. If two people in the same home both qualify, the limit applies per person.

The $20,000 cap has applied since the 2022 tax year. Before that the ceiling was lower, at $10,000. At 15% of a full $20,000, the most a household can recover in one year is $3,000.

What the credit does not cover

Cosmetic work does not qualify. Neither does work that adds value without improving accessibility, such as a new kitchen for its own sake. Routine repairs, appliance purchases and financing costs are also outside the credit.

If you receive a grant or reimbursement for the work, you generally have to reduce your claim by that amount. The CRA instructions for line 39800 and Schedule 12 set out the line-by-line calculation.

Where provincial programs fit

The federal credit is not the only money available. The Canada Mortgage and Housing Corporation (CMHC) runs programs that help older homeowners and people with disabilities pay for adaptations. The CMHC Home Adaptations for Seniors program is one route for households that need help with the upfront cost.

Ontario Renovates and British Columbia's Rebate for Accessible Home Adaptations (RAHA) are two provincial examples.

Medical Expense Tax Credit: lines 33099 and 33199 and the accessibility items listed

The METC is the older and broader of the two credits. It lets you claim a wide range of medical expenses, including some that relate to a home, on lines 33099 and 33199.

Line 33099 is for the taxpayer, their spouse or common-law partner, and their minor children. Line 33199 is for other dependants. The eligible medical expenses page lists what the CRA accepts under each line.

The METC uses a threshold. You can only claim the portion of eligible expenses above the lesser of 3% of your net income and a fixed dollar amount that the CRA sets for the year. That threshold means small claims often produce no credit, while larger ones do. Guide RC4064, Medical and disability-related information, gives the current fixed amount and the full list of eligible expenses.

Items that relate to a home

The list of eligible medical expenses includes several items that touch on housing. They include alterations to a home to accommodate a person with a severe and prolonged mobility impairment, and devices and equipment prescribed by a medical practitioner.

Examples include:

Some items need a prescription or a written certification from a qualified practitioner. Others need only a receipt. The rule depends on the item, so check the CRA list before you buy.

How the METC interacts with the HATC

In practice, many households use the HATC for the renovation itself and the METC for devices and care. That keeps the two claims clean and easy to defend.

The METC for home accessibility work is filed alongside other family and caregiver claims. The CRA groups these on its family, child care, and caregivers page, which is the starting point for caregivers filing on behalf of someone else.

Which accessible home design changes survive CRA scrutiny

The CRA does not publish a single approved list of renovations. It publishes rules, and it expects the work to fit them. The strongest claims share a few features.

First, the work serves someone who qualifies: a person eligible for the DTC or 65 or older for the HATC, and a person with the prescription or certification the METC requires. Second, the change addresses a functional need, not a style preference. Third, the paper trail shows who prescribed or recommended it and what it cost.

The qualifying modification list in practice

Think of the work in categories. Access into and around the home, safety in wet areas, and the ability to use a kitchen or bedroom independently are the three that hold up best.

Work that draws questions

Whole-home remodels with an accessibility component are harder to defend. If half the invoice is a new kitchen and half is a widened hallway, expect the CRA to ask which portion was for accessibility.

Ask your contractor to separate the invoice by task. A line for "accessibility modifications" with a lump sum is weaker than itemised costs for each change.

Climate and code realities

Canadian renovations face conditions that shape both cost and design. A ramp in Winnipeg needs to handle snow and ice. A bathroom in St. John's needs to manage humidity. These choices affect materials, not eligibility, but they affect the budget you are trying to offset.

Provincial building codes also apply. Ontario, British Columbia, Quebec, Alberta and the Atlantic provinces each enforce their own rules, and a permitted alteration is easier to document than one done without a permit.

Accessibility Standards Canada and the Canadian Standards Association publish standards that inform good practice, even where they are not tax rules. If cost is the sticking point, the guide to grants, loans, and waivers sets out the programs that can sit alongside a tax claim.

Documenting the work: receipts, prescriptions and contractor invoices

The CRA does not ask for receipts when you file. It asks later, during review. A claim with no paperwork is a claim that gets reversed.

Keep a folder, digital or paper, for every expense you intend to claim. Add to it as the work happens, not after the tax year ends.

What to keep for each expense

For the METC, some items need a prescription from a medical practitioner. For the HATC, a written assessment from an occupational therapist or similar professional strengthens the case that the work was needed.

Numbered steps for a clean claim

When a grant reduces your claim

If a program such as the Residential Rehabilitation Assistance Program (RRAP) or a provincial grant like Ontario Renovates or RAHA pays part of the bill, your eligible expense drops by that amount. Report the reimbursement and claim only the portion you paid.

Grants, subsidies and insurance payments reduce the eligible base before the 15% is applied.

This is where a lot of claims go wrong. Households claim the full invoice, then a review finds the grant, and the whole claim is questioned. Declare the grant from the start.

Claiming both credits without triggering a reassessment

A reassessment is not a punishment. It is the CRA asking for proof. Most claims survive if the paperwork matches the rules, and most problems come from a mismatch between what was claimed and what can be shown.

The overlap rule

You cannot claim the same expense for both credits in the same year. Choose one, or allocate the expense clearly. If you allocate, write down which portion went to which credit and why.

A common approach is to put the renovation on the HATC and the devices on the METC. That is easy to explain and easy to document.

Common triggers

If the CRA asks questions

Respond with the documents, not with argument. Send the invoice, the proof of payment, the prescription and the DTC certificate. If part of the claim is disallowed, you can ask for a review.

The disability deductions and credits hub on the CRA site is the reference point for how the pieces fit together. The disability deductions and credits page links the DTC, the METC and related claims in one place.

Planning the renovation around the credits

Budget the work with the credit in mind. Typical accessibility renovations vary widely. A bathroom conversion often falls in the $15,000 to $30,000 range, while a stair lift installs for $3,000 to $10,000.

A $20,000 qualifying renovation yields a credit of about $3,000, so the net cost is lower, but the cash still has to be found first. Grants, loans and the credit all arrive at different times.

For a fuller picture of what the work actually costs and where budgets slip, the notes on accessible renovation costs are a useful companion. So is the piece on first principles as of 2027, which covers the hidden expenses that rarely appear in a quote.

Start the paperwork before the first hammer swings. The credit is only as good as the evidence behind it.
