The GST/HST new housing rebate and the new residential rental property rebate return part of the tax paid on a newly built or substantially renovated home. They are valuable, widely claimed, and heavily reviewed. Few GST/HST items are reassessed as often, because the rebates turn on the buyer's intention and use — facts the Canada Revenue Agency can test after the fact against occupancy records, leases, and resale activity. A rebate that was claimed in good faith can be clawed back years later, with the full GST/HST on the purchase becoming payable plus interest.
This guide explains who is eligible, the primary-place-of-residence test that drives most disputes, the situations in which rebates are denied or clawed back, the particular problem of assignment sales, and how to dispute a denial through the objection process. It is general information, not legal advice for a particular transaction. For the broader audit context, see our GST/HST audit defence guide.
The two rebates, in outline
There are two distinct rebates that often get conflated.
The new housing rebate is available to an individual who buys a new or substantially renovated home from a builder, or who builds or substantially renovates a home, where the home is for use as the primary place of residence of the individual or a qualifying relation. In practice, on a purchase from a builder, the rebate is frequently credited at closing — the builder reduces the price by the rebate amount and claims it from the CRA, having the buyer assign the rebate to the builder. The buyer signs the rebate forms, and the buyer remains responsible for the eligibility representations made in them.
The new residential rental property rebate applies where the property is purchased or built to be rented to a tenant who will use it as a place of residence on a long-term basis. Because a rental property is not the buyer's own primary residence, the new housing rebate is not available — the rental rebate is the correct one. The rental rebate is claimed by the landlord after the fact, not credited at closing, and it carries its own application and its own evidentiary expectations.
Both rebates have a federal component and, in harmonized provinces, a provincial component, each with its own thresholds and phase-outs. The structural point for disputes is that the rebates are mutually exclusive at the level of a given unit and turn on how the property is in fact used: owner-occupied as a primary residence points to the housing rebate, long-term rental points to the rental rebate, and a property held for resale points to neither.
A further structural feature drives the volume of disputes in this area: the rebate is conditional on facts that unfold after the claim is made. The new housing rebate is claimed at or shortly after closing, but its validity depends on what the buyer then does with the home over the following months and years — whether the buyer moves in, how long they stay, and whether the home is sold or rented. The CRA therefore has the ability to revisit a rebate well after the fact, comparing the intention represented at the time of purchase against the buyer's actual conduct. A rebate is not "final" simply because it was paid or credited at closing; it remains open to review within the normal assessment period, and the burden of showing that the eligibility conditions were met rests with the person who claimed it. Understanding that the claim is provisional in this sense is the key to keeping the records that will support it if the CRA later asks.
Eligibility and the primary-place-of-residence test
The new housing rebate is conditional on the home being acquired for use as the primary place of residence of the buyer or a qualifying relation (a spouse or common-law partner, or certain other relations). "Primary place of residence" is not the same as a place the buyer sometimes stays. It is the place the individual makes their main home — where they live on a settled and ongoing basis, where their mail and identification point, and which is central to their daily life.
The CRA assesses intention as of the time the agreement of purchase and sale is entered into, and tests that intention against what actually happened. The indicators it weighs include: whether and when the buyer actually moved in; how long the buyer occupied the home before any sale or change of use; the buyer's address on identification, tax returns, and registrations; whether the home was listed for sale or rent shortly after closing; and the buyer's pattern across multiple property transactions. No single factor is decisive, but the picture they form usually is.
The most common factual disputes are about whether the buyer's intention was genuinely to occupy the home as a primary residence, or whether the property was acquired as an investment — to flip on completion, to hold for appreciation, or to rent. Where the CRA concludes the primary-residence intention was absent, it denies the housing rebate. If the property was in fact a rental, the rental rebate may be the correct claim instead, but it has to be claimed on its own terms and within its own time limits.
Common denials and clawbacks
The reassessment scenarios in this area recur with some regularity:
- New housing rebate clawback for non-occupancy. The buyer claimed the rebate but did not move in, or moved in only briefly before selling or renting. The CRA claws back the rebate, and the full GST/HST on the purchase becomes payable.
- Primary-intention disputes. The CRA forms the view that the buyer's primary intention at the time of purchase was investment rather than personal residence — often inferred from a quick resale, an early lease, or a series of similar transactions.
- Wrong rebate claimed. The buyer claimed the new housing rebate on a property that was always intended as a rental; the housing rebate is denied, and the rental rebate (if available) has to be pursued separately and on time.
- Qualifying-relation issues. The rebate was claimed on the basis that a relation would occupy the home, but the relation did not qualify or did not in fact occupy it as a primary residence.
- Self-supply under section 191. A builder or substantial renovator who first occupies or rents out a residential unit is deemed under section 191 of the Excise Tax Act to have made a taxable sale of the unit to itself at fair market value, producing GST/HST liability even without a third-party sale. Misjudging the self-supply timing is a frequent and substantial adjustment.
- Substantial-renovation reclassification. A renovation the owner treated as substantial (and therefore as creating a "new" home eligible for the rebate) is reassessed as falling short of the technical threshold — or, conversely, a project treated as ordinary repair is reclassified as substantial renovation with new-home consequences.
- Documentary inconsistencies. Mismatches between the rebate application, the closing documents, the occupancy date, and the buyer's other filings draw scrutiny and denial.
Because the rebate is often credited at closing, a clawback frequently lands on the buyer well after the money has been spent on the home, which is why these reassessments are disruptive out of proportion to their visibility at the time of purchase.
Assignment sales
Assignment sales — where a buyer who has signed a pre-construction agreement sells the rights under that agreement to a new buyer before closing, rather than taking title and reselling — have become a focus of GST/HST attention, and they create two distinct issues.
First, the assignment itself can be a taxable supply. The consideration for an assignment, including the portion attributable to the assignor's deposit and any profit, can attract GST/HST, and the obligation to collect and remit it can fall on the assignor. Recent changes made assignment sales of new or substantially renovated residential housing taxable in a more systematic way, which has increased both the compliance burden and the audit exposure for assignors who did not treat their assignment as a taxable supply.
Second, an assignment is strong evidence about the original buyer's intention. A buyer who assigns the contract before closing did not occupy the home as a primary residence — the home was never completed in their hands — and the assignment is often taken as confirmation that the property was acquired for resale rather than as a residence. That can defeat any new housing rebate the assignor claimed or would have claimed, and it can colour the CRA's view of a buyer's pattern across multiple pre-construction purchases. Where an assignor has engaged in repeated assignments, the CRA may also consider whether the activity amounts to a business, with consequences that extend beyond the rebate.
Disputing a rebate denial
The dispute path for a rebate denial or clawback runs through the same objection-and-appeal framework as any other GST/HST assessment.
Engage the proposal letter. If a proposal letter precedes the reassessment, that is the place to put forward the evidence of intention and occupancy and to make the legal submissions, before the assessment is on the books.
File the notice of objection in time. A notice of objection must be filed within 90 days of the date of the assessment under section 301 of the Excise Tax Act. The objection goes to an Appeals officer who reviews the file independently of the auditor. Our guide on how to file a notice of objection sets out the steps and deadlines.
Build the evidentiary record on intention and use. Because these disputes turn on facts, the response is evidentiary. Utility connection and transfer records, mail and identification showing the address, the timing and duration of occupancy, moving records, and the absence of an early listing or lease all support a genuine primary-residence intention. Where the property was in fact a rental, the focus shifts to establishing the correct rental rebate claim and its timing.
Appeal to the Tax Court if needed. If the objection does not resolve the matter, an appeal lies to the Tax Court of Canada within 90 days of the notice of decision. The court hears smaller GST/HST matters under the Informal Procedure and larger ones under the General Procedure. Our overview of the Tax Court appeal process describes what that stage involves.
As with other GST/HST assessments, the resulting balance is generally collectible while the dispute is outstanding, so a buyer facing a substantial clawback should plan for the cash-flow consequences alongside the substantive dispute.
How Barrett Tax Law approaches rebate disputes
Our approach to a new housing or rental rebate dispute starts with the facts that drive it. We assemble the record of intention and use — the timing of occupancy, the buyer's identification and filings, the presence or absence of an early listing or lease, and the buyer's history across any related transactions — and we match that record against the statutory test the CRA has applied. Where the wrong rebate was claimed, we assess whether the correct rebate remains available and on time. Where a self-supply or substantial-renovation characterization is in issue, we work through the technical test on its own terms. We make the submissions at the proposal-letter stage where the opportunity exists, carry the dispute into a notice of objection, and prepare for the Tax Court where the objection does not resolve the matter, while planning for collections in parallel.
If your new housing or rental rebate has been denied or clawed back, the most useful first step is to preserve the records that show how the property was actually used and to note the objection deadline on any assessment you have received.
