Get Home Realty · 2026-04-12
The HST rebate can materially affect the final cost of a new construction home. Builders often advertise prices assuming the buyer qualifies and assigns the rebate back to the builder on closing.
Before signing, review intended use, occupancy timing, and whether the purchase is for a principal residence or investment. A licensed accountant should confirm tax eligibility for your situation.
Use the calculator below as a planning tool before you compare projects. It estimates the potential savings from expanded new-home HST relief based on the listed sale price, existing rebate assumptions, and the proposed phase-out range.
