🏗️What Is HST on New Homes in Ontario?

HST in Ontario is 13% total — made up of 5% federal GST and 8% provincial tax. On new construction, this applies to the full purchase price, which is a significant cost that can catch buyers off guard.

This applies to new construction homes, pre-construction condos, and substantially renovated properties.

🔑Types of HST Rebates in Ontario

1. New Housing Rebate (Primary Residence)

This is what most buyers ask about. It applies when you — or a close relative — will actually live in the home as a primary residence. You must be buying as an individual, not a corporation (with some exceptions).

2. New Residential Rental Property Rebate

This is for investors purchasing to rent long-term. The property must be used as a qualifying long-term rental and meet CRA rental conditions. The paperwork and ownership structure must be handled carefully from day one.

3. Assignment Sales (Where People Get Burned)

If you assign a pre-construction unit before taking possession, you may lose rebate eligibility entirely and owe the full HST. This is one of the most expensive surprises in Ontario real estate — and one of the most avoidable with proper guidance.

✅HST Rebate Eligibility in Ontario (2026)

Basic Eligibility

The buyer must be an individual (not a corporation in most cases). The property must be your primary residence, or a qualifying long-term rental if claiming the rental rebate. You must actually use the property as you declared when filing.

Price Thresholds — Where Math Starts to Hurt

This matters enormously for buyers in York Region, Peel Region, and the broader GTA, where average prices far exceed federal thresholds. Missing the Ontario portion because you assumed both were gone is an expensive mistake.

📊How Is the HST Rebate Calculated? (Step-by-Step)

Here's exactly how to think through the math — no jargon, just numbers.

• 1
  Calculate Total HST on the Purchase

  Purchase price × 13% = Total HST. On a $600,000 home: $600,000 × 0.13 = $78,000 in HST.
• 2
  Apply Federal Rebate (if eligible)

  Full rebate only up to $350K. Phases out at $450K. For homes above $450K, federal rebate = $0.
• 3
  Apply Ontario Rebate (if eligible)

  Maximum $24,000. Still available even on higher-priced homes — if you meet all conditions.
• 4
  Calculate Net HST Paid

  Total HST minus applicable rebates = what you actually owe (or what the builder credits back).

📋 Example: $600,000 New Home

You're not getting the tax back. You're getting some of it back — if you qualify and structure it correctly.

🏗️HST Rebate on Pre-Construction Homes

Pre-construction is where HST rebate misunderstandings happen most often.

How Builders Handle It

Most builders factor the rebate into their pricing structure — meaning the contract price you see already assumes you'll qualify and credits the rebate back to you at closing. The base price plus HST minus rebate is what you're actually paying.

The Risk Nobody Fully Explains

If you later fail to qualify — because you don't move in, you rent the unit when you said you wouldn't, or you assign the property — CRA can deny the rebate. At that point, you owe the builder the rebate amount they already credited you. That's often $24,000+ out of pocket at closing.

📍What This Means Across Southern Ontario

The rebate plays out differently depending on where you buy — because price points vary significantly across the region.

🚨Common HST Rebate Mistakes That Cost Real Money

• "It's automatic." It's not. You must meet all conditions, file the correct forms with CRA, and ensure the deal is structured properly from the beginning.
• "HST included means I'm safe." That phrase only describes how the builder presents pricing — not your eligibility. If the rebate is denied, you pay the difference.
• Misunderstanding occupancy rules. If you claim primary residence but rent the unit out instead, CRA can deny or claw back the rebate. You must actually live there as declared.
• Overestimating the rebate on higher-priced homes. Above $450K, the federal portion disappears. You may only have the Ontario rebate available — or nothing, if other conditions aren't met.
• Assigning without understanding tax consequences. Pre-construction assignments can eliminate rebate eligibility entirely and trigger the full HST — a surprise many assignment sellers discover at closing.
