Buying a new construction home in Ontario is an exciting prospect. A key financial benefit to soften the blow of closing costs is the GST/HST New Housing Rebate. This program can refund a significant portion of the federal tax you pay, potentially saving you thousands.
However, a critical and often misunderstood complication arises with co-ownership. Whether you're buying with a spouse, a friend, a family member, or an investment partner, the rules for the rebate are strict. A simple mistake in how you structure your ownership agreement can lead to your rebate application being denied entirely.
This guide will clarify the complex GST/HST New Housing Rebate rules for co-ownership situations, ensuring you don't unknowingly leave money on the table.
What is the GST/HST New Housing Rebate?
When you purchase a newly built home from a developer, the price includes GST or the federal portion of HST. The New Housing Rebate program is designed to refund some of this tax, provided the home is intended to be your primary place of residence.
The rules can be complex, but the most important principle for co-buyers to understand is this: for a rebate to be approved, generally all co-owners must meet the eligibility criteria.
The Co-Ownership Challenge: Common Scenarios That Cause Problems
The Canada Revenue Agency (CRA) looks at the ownership group as a whole. If one person in the group is ineligible, it can disqualify everyone. Let's break down the most common scenarios.
Scenario 1: One Co-Owner is Not a First-Time Buyer
With the introduction of the enhanced First-Time Home Buyers' GST Rebate in 2025, this scenario is more relevant than ever. If you are buying with a partner who has owned a home before, it can complicate your eligibility for this specific enhanced rebate. The core principle remains that the property must be for the primary use of all purchasers or their relations.
Scenario 2: Buying with a Corporation or Partnership
This is a critical point for investors. The GST/HST New Housing Rebate is intended for individuals, not corporate entities. If you structure your purchase so that a corporation or a partnership is on the title of the property along with an individual, you will generally be ineligible for the rebate. The CRA's position is that a corporation cannot have a "primary place of residence."
Scenario 3: One Co-Owner Does Not Intend to Live in the Property
Perhaps you are buying with a parent who is co-signing to help with the mortgage but has their own home and will not be living with you. For the standard rebate, the property must be the primary place of residence for at least one of the purchasers. However, if any co-owner purchased their interest in the property for the primary purpose of selling it or leasing it out, it can void the rebate for everyone.
The Key to Eligibility: The "Primary Place of Residence" Rule
The foundation of the GST/HST New Housing Rebate is that the home will be used as a primary residence. When you have multiple owners, the CRA needs to be satisfied that this condition is met by the ownership group.
-
For Individuals: If you and your co-owner(s) will all be living in the home, you are on the right track.
-
For "Relations": The rules do allow for the home to be the primary residence of a "relation" (e.g., a child, parent, or spouse) of one of the owners. This can provide some flexibility, but the ownership structure must still be carefully planned.
