Canada’s Multigenerational Home Renovation Tax Credit: Eligibility and Planning
Canada’s Multigenerational Home Renovation Tax Credit (MHRTC) may reduce the eventual cost of a specific kind of project: creating a qualifying secondary unit so a senior or an adult eligible for the Disability Tax Credit can live with a qualifying relative. It is a federal refundable tax credit, not a general renovation rebate and not an upfront discount on a contractor’s invoice.
The current Canada Revenue Agency (CRA) program page shows a 14.5% credit on up to C$50,000 in qualifying expenses, for a maximum credit of C$7,250. The page labels those headline amounts for tax year 2025. CRA’s current claiming instructions give an example of a renovation completed in 2026 being claimed on the 2026 tax return. Confirm the applicable year’s instructions before relying on the amount or filing rules.
Start with the household, then the project
The credit has both household and building tests. A project does not qualify just because it is called an in-law suite, basement apartment, ADU, garden suite, or secondary suite. The CRA describes a qualifying secondary unit as a self-contained unit with a private entrance, kitchen, bathroom, and sleeping area. It must be newly constructed or created from existing living space that did not already meet local requirements to be a secondary dwelling unit, and it must meet applicable local rules, permits, codes, and bylaws.
The unit must allow a qualifying individual and a qualifying relative to live together. CRA defines the qualifying individual as a senior who is at least 65 years old at the end of the relevant tax year or an adult eligible for the Disability Tax Credit. A person claiming the credit must also meet CRA’s eligible-individual rules, including Canadian tax residency for the claim year and having incurred the expenses. The current eligibility checklist requires the qualifying individual and relation to ordinarily live, or reasonably expect to live, in the home and unit within 12 months after the renovation period ends. The detailed CRA relationship rules decide which family members qualify to claim.
Before spending on a design, write down who will live in each space, what makes the secondary unit self-contained, and which authority will confirm that configuration. A project can meet a family’s practical needs while failing a tax test, or it may qualify for the credit but require additional work to meet local dwelling requirements.
How the credit amount works
For the tax year shown on CRA’s current program page, the credit is 14.5% of eligible expenses, up to C$50,000 for one qualifying renovation. The maximum is therefore C$7,250. The 14.5% applies to qualifying expenditures, not automatically to the full construction contract or the whole cost of an addition. Because the credit is refundable, the calculated amount can result in a tax refund when it is greater than the tax otherwise owing; the return still applies all other tax calculations and eligibility rules.
For example, if a qualifying household has C$40,000 in eligible expenses, the calculation at the published rate is C$40,000 × 14.5%, or C$5,800. If eligible expenses total C$70,000, the C$50,000 cap limits the calculation to C$7,250. These examples assume the household, project, claimant, and costs meet CRA’s rules; they are not estimates of the likely credit for a particular home.
When more than one eligible individual shares costs, claimants can divide eligible expenditures they personally incurred, but their combined claim for the qualifying renovation cannot exceed C$50,000. CRA also states that only one renovation can be claimed for a qualifying individual during that individual’s lifetime. Do not count the same expense twice or assume each family member can claim a separate maximum for the same person and project.
Which costs may count
CRA says qualifying expenditures must be reasonable and directly attributable to the qualifying renovation, incurred by an eligible individual or qualifying trust during the renovation period, and supported by records. Examples can include professional services, building materials, fixtures, equipment rental, plans, and required permits. The program is based on amounts paid or incurred, not the homeowner’s estimate of the project’s value.
CRA lists costs that do not qualify, including routine repair and maintenance, household appliances, financing costs, reimbursed amounts, and expenses already claimed under certain other credits. The value of the homeowner’s own labor and tools is not an eligible expense. Special rules also apply when a related person performs paid work; the CRA says those expenses are not eligible unless that person is registered for GST/HST and the other requirements are met.
This is why the renovation budget and the tax worksheet should be separate. A building contract may bundle eligible and ineligible items. Ask the contractor for descriptions and invoices that distinguish construction services, appliances, financing, routine work, and any reimbursed or credited amount. CRA’s current list controls, so do not classify a line item based only on its name.
When and how to claim
Claim the renovation in the tax year when the renovation period ends, even if construction began in an earlier year. CRA describes the period as starting with the first qualifying expenditure and ending when the qualifying renovation is complete, such as after final inspection or other proof of completion. Its current example says that when a qualifying project completes in 2026, an eligible person claims it on a 2026 tax return. This completion-year rule matters for projects that run across more than one calendar year: expenses may be incurred over time, but the claim is made for the year the renovation period ends.
The person making a claim must be an eligible individual who incurred the expenses. Where eligible family members share costs, CRA requires each person to claim only qualifying expenditures they incurred and keeps the combined total within the cap. The credit is reported through the applicable CRA form and schedule for the relevant tax year. A tax preparer can help resolve who should claim shared expenses and whether a renovation meets the relationship rules.
Plan who will pay for which parts of the work before invoices are issued. If two family members share expenses, they should keep records that show who incurred each cost and agree how the total will be allocated within the shared cap. Do not assume that a person who lives in the unit can claim costs paid by another household member, or that splitting payments creates a higher project maximum.
Keep contracts, change orders, paid invoices, receipts, proof of payment, permit records, and completion or inspection documents. CRA says supporting records should identify the vendor, goods or services, work performed, property address, dates, amount, and proof of payment. Retain the documents with the tax file even if the contractor’s invoice uses broad descriptions.
Include timing in the project cash flow
Because the credit is claimed through a tax return for the completion year, it should not be treated as cash available to pay a deposit, progress payment, or change order while work is underway. Plan how the household will fund the project first. If considering a mortgage or another borrowing route, compare the financing costs separately; the MHRTC page does not promise loan approval or make financing costs eligible for the credit.
The possible credit can be one input when comparing a new addition with a basement conversion or detached unit, but it does not establish that the most expensive design is financially preferable. Model the full construction cost, local approval path, temporary living, contingency, and the family’s preferred level of independence. Then apply only those expenses that meet the CRA rules.
Keep the tax calculation beside the project budget rather than subtracting the maximum credit from every early estimate. First identify the costs that could be eligible and when they will be paid. Then separately record the possible credit, the return year, the documentation still needed, and any uncertainty about household qualification. That prevents a hypothetical tax result from making an otherwise unaffordable deposit or progress payment appear available.
A pre-construction checklist
- Confirm that the intended occupant meets the qualifying-individual definition and check the qualifying relative rules with CRA.
- Verify that the proposed unit is self-contained, newly created for the program, and recognized under local requirements.
- Ask a tax professional how shared expenses, prior claims, trusts, reimbursements, and other credits affect the household.
- Separate likely qualifying expenditures from appliances, financing, routine work, and other excluded items.
- Keep invoices and proof of payment as the work progresses, rather than rebuilding the record after completion.
- Recheck the CRA rate, cap, forms, and tax-year instructions when the renovation is completed.
The MHRTC can matter to a narrow but important multigenerational project. Treat it as a later tax claim with exact eligibility and documentation rules, while making the construction and financing decision on the full project budget.
