Accessibility renovations as medical expenses: the CRA's two conditions

Families who renovate so a parent or child can keep living at home often hear that the work is 'tax deductible' and then find, at tax time, that most of the invoice does not qualify. The CRA's medical expense rules for renovations are narrower than people expect, and the claim depends on records that are easy to collect during the job and hard to rebuild afterwards.

Who the rule is for

The CRA's page 'Details of medical expenses' describes renovation or construction expenses as amounts paid for changes that give a person access to, or greater mobility or functioning within, their home. The person must have a severe and prolonged mobility impairment or lack normal physical development. The rule covers renovating or altering an existing home and the incremental costs of building the person's main residence.

The two conditions

The expenses must be reasonable and must meet both conditions: they would not normally be expected to increase the value of the home, and they would not normally be incurred by people with normal physical development or without a severe and prolonged mobility impairment. A new kitchen that also happens to have lower counters does not become a medical expense; the extra cost of the accessible feature is what the rule is about. The CRA's examples are outdoor or indoor ramps, widened halls and doorways, and lowered kitchen or bathroom cabinets.

Records you need

The CRA says you need a cost breakdown and receipts, and you must be able to show that the person's circumstances and the expenses meet all conditions. Ask the contractor to invoice the accessibility work as separate lines, rather than one lump sum for the whole renovation, and keep the plans or notes that show why each change was needed. Related rebates, such as GST/HST rebates, are subtracted from the amount claimed.

The Home Accessibility Tax Credit too

The CRA says that if the renovation also qualifies for the Home Accessibility Tax Credit, you could claim both the HATC and the medical expense tax credit for these expenses. The two credits have different eligibility rules, so check each one; ArtBuild's article on the Home Accessibility Tax Credit covers that credit.

Moving and driveways

The same CRA page covers two related items. Reasonable moving costs to more accessible housing can be claimed for a person with a severe and prolonged mobility impairment, if not already claimed as moving expenses, up to a limit set on the page. Reasonable amounts paid to alter the driveway of the main residence can be claimed if the change eases the person's access to a bus. Check the current page for limits before filing.

Prevention Checklist

• Confirm the person has a severe and prolonged mobility impairment or lacks normal physical development.
• Separate accessibility items from general renovation work on the invoice.
• Keep receipts, a cost breakdown and notes on why each change was needed.
• Subtract any rebates you receive, such as GST/HST rebates.
• Check whether the same work also qualifies for the Home Accessibility Tax Credit.
• Read the current CRA page before filing; limits and rules can change.
