Canada's housing affordability crisis prompted a significant federal tax measure in fall 2023: the removal of GST on newly constructed purpose-built rental housing. This change — enacted retroactively to September 14, 2023 — makes the construction of apartment buildings, student residences, and long-term care facilities dramatically more tax-efficient. For developers, builders, and investors, understanding exactly how the enhanced GST New Residential Rental Property (NRRP) rebate works is essential to project economics.
Under the old rules, the GST New Residential Rental Property Rebate provided a partial rebate of 36% of the 5% GST, up to a maximum of $6,300 per unit — but the rebate phased out entirely for units valued above $450,000 (fair market value). In major cities like Calgary and Vancouver where new construction routinely exceeds these thresholds, the rebate was worth little or nothing.
Under the enhanced rules, the rebate is 100% of the federal portion of GST (the full 5% federal component), with no phase-out based on property value. For a $600,000 unit, this represents a $30,000 rebate per unit — compared to zero under the old rules.
To qualify for the enhanced NRRP rebate, the project must be:
| Feature | Old Rebate | Enhanced Rebate (2023+) |
|---|---|---|
| Rebate amount | 36% of 5% GST | 100% of 5% GST |
| Maximum rebate per unit | $6,300 | No cap |
| Phase-out threshold | Starts at $350K, ends at $450K | None |
| Minimum units | 1 | 4 apartment units (or 10 rooms) |
In HST provinces (Ontario at 13%, New Brunswick, Newfoundland, Nova Scotia, PEI at 15%), the combined GST/HST applies to new construction. The enhanced rebate covers the federal component only. Separate provincial NRRP rebate applications are required for the provincial component — and the provincial rules may differ. Alberta has no provincial sales tax, so Calgary developers benefit from the federal rebate only (5% GST).
The NRRP rebate is claimed on Form GST524 (GST/HST New Residential Rental Property Rebate Application). The application must be filed within two years of the later of the date the complex was substantially completed or the date of first rental occupancy. For large projects with multiple buildings or phases, separate applications may be required for each qualifying residential complex.
