The Ontario new home HST rebate is no longer just a proposal. The enhanced program is now here, and eligible new build buyers may be able to receive significant HST relief. Here is what Ottawa buyers need to know before signing a builder agreement.
A few months ago, I wrote about Ontario’s proposed changes to the new home HST rebate.
At the time, there was a lot of noise.
Big headlines.
Big numbers.
Not a lot of clarity.
Now we have more clarity.
The Ontario Temporary Enhanced New Housing Rebate is no longer just something being talked about. The Canada Revenue Agency has now released guidance on how the enhanced program works for buyers purchasing a new home from a builder.
If you are looking at new construction in Ottawa, you need to understand this before you sign anything.
Because this is not a small rebate.
For eligible buyers, the potential HST relief can be up to $130,000.
That can change the numbers in a serious way.
But it is also not automatic. Not every buyer qualifies. Not every purchase works the same way. Not every builder process will be identical.
So let’s break this down properly.
No tax jargon.
No government nonsense.
Just what buyers actually need to know.
For the official CRA guidance, you can review the Canada Revenue Agency page here:
Ontario Temporary Enhanced New Housing Rebate
I also wrote about the original proposed HST rebate changes here:
Ontario’s New HST Rebate Explained 2026
This article is the updated version now that the enhanced Ontario program and CRA process are clearer.
What Changed Since My Last HST Rebate Blog?
My first article explained what Ontario had announced and what still needed to be clarified.
The big issue at the time was that buyers were hearing “up to $130,000” everywhere, but the details were still developing.
Now the structure is clearer.
There are two main pieces buyers need to understand:
The Ontario Enhanced New Housing Rebate
The Ontario 5% top up
Together, these may provide up to $130,000 in potential HST relief for eligible new home buyers.
This is different from the earlier conversation around first time home buyers.
That is the part people need to catch.
The enhanced Ontario program is its own thing. It interacts with first time home buyer rebates, but it is not the exact same conversation as before.
What Is The Ontario Enhanced New Housing Rebate?
The Ontario Enhanced New Housing Rebate is temporary enhanced HST relief for eligible buyers purchasing a new or substantially renovated home.
In plain English:
Ontario is allowing eligible buyers to recover up to $80,000 of the provincial portion of HST paid on a qualifying new home.
That provincial portion is the 8% Ontario part of the HST.
For eligible new homes valued up to $1,000,000, the rebate can cover 100% of the 8% provincial portion.
For eligible new homes valued between $1,000,000 and $1,500,000, the maximum provincial rebate can remain at $80,000.
For eligible new homes valued between $1,500,000 and $1,850,000, the rebate is reduced.
For homes valued at $1,850,000 and above, the existing Ontario new housing rebate rules may still apply, generally at the previous flat amount.
That is the official structure.
But here is the part buyers actually care about:
This can materially reduce the HST burden on a new build.
And in a market where affordability is already tight, that matters.
What Is The Ontario 5% Top Up?
In addition to the Ontario Enhanced New Housing Rebate, Ontario is also providing a 5% top up.
This is where people get confused, so I’ll keep it simple.
The Ontario Enhanced New Housing Rebate can cover up to the 8% provincial portion of HST.
The Ontario 5% top up can provide additional Ontario relief.
Together, the two pieces can create total potential relief of up to $130,000.
The clean buyer friendly breakdown is:
Up to $80,000 through the Ontario Enhanced New Housing Rebate
Up to $50,000 through the Ontario 5% top up
Up to $130,000 in total potential relief
Do not overcomplicate it.
That is the way buyers should think about it.
Who May Qualify For The New Home HST Rebate?
You may qualify if:
You are buying a newly built or substantially renovated home
The home will be your primary place of residence
Your agreement of purchase and sale is signed between April 1, 2026 and March 31, 2027
The builder participates in the credit process
All program requirements are met
This is where buyers need to slow down.
Just because the rebate exists does not mean every buyer automatically gets it.
If you are buying a resale home, this does not apply.
If you are buying purely as an investment, the rules may be different.
If the home is not your primary residence, you need proper advice before assuming anything.
If the builder is not handling the assignment and credit process properly, you need to understand that before closing.
Do not sign first and ask questions later.
That is backwards.
How Does The Rebate Work When Buying From A Builder?
In many new build purchases, the buyer may assign the rebate to the builder.
That means the builder can credit the buyer for the available rebate at closing.
This is important.
Most buyers do not want to pay the full amount and then wait around hoping to recover money later.
The cleaner process is usually that the builder applies the available relief at closing, reducing the final amount payable by the buyer.
A simplified version looks like this:
Buyer purchases a qualifying newly built home
Buyer completes the required rebate forms
Buyer assigns the available rebate to the builder
Builder credits the buyer at closing
Builder reports the GST/HST collected on the sale
Builder submits the required rebate paperwork
CRA reviews the rebate information
Ontario processes the 5% top up payment to the builder
The CRA refers to forms including GST190 and RC7190 ON.
That is the paperwork side.
The buyer side is much simpler:
Make sure the builder is applying the rebate properly and make sure you understand what is being credited at closing.
Use My New Home HST Rebate Calculator
Because the math can get confusing fast, I built a simple tool to help buyers estimate the potential rebate.
You can use my calculator here:
New Home HST Rebate Calculator
The calculator is designed to help you get a clearer idea of what the numbers may look like based on the purchase price, whether HST is included, and which rebate rules may apply.
It is not a replacement for legal, tax, or accounting advice.
But it is a very useful starting point before you sign a builder agreement.
The Big Mistake Buyers Make
The biggest mistake buyers make is assuming the builder will explain everything clearly.
Maybe they will.
Maybe they will not.
But the builder’s sales office is not your independent advisor.
Their job is to sell the home.
Your job is to understand the deal before you sign.
That means asking the right questions:
Is the purchase price HST included or plus HST?
Does this home qualify for the enhanced rebate?
Will the builder credit the rebate at closing?
What forms do I need to sign?
What happens if eligibility is denied?
Is the agreement date inside the eligible window?
Is this being treated as my primary residence?
What is the final amount payable after rebate credits?
These are not annoying questions.
These are smart buyer questions.
And when the numbers can be this large, you need to ask them.
HST Included Versus Plus HST
This is one of the most misunderstood parts of new construction pricing.
A lot of new build prices are advertised as HST included.
If a home is advertised at $1,000,000 including HST, you do not calculate the HST by simply taking 13% of $1,000,000.
That would be wrong.
To back out the HST from an HST included price, you divide the total price by 1.13.
Example:
Total purchase price including HST: $1,000,000
Price before HST: $884,955.75
Included HST: $115,044.25
Potential relief: up to $115,044.25
Now compare that to a home priced at $1,000,000 plus HST.
In that case, the HST would be $130,000.
Same million dollar number.
Very different result.
This is exactly why buyers need to understand the structure before getting excited about the headline rebate amount.
The rebate can be powerful.
But the math has to be done properly.
Before you rely on the headline number, run the numbers here:

Is This Only For First Time Home Buyers?
No.
This is one of the most important updates.
The enhanced Ontario rebate is not just the old first time buyer conversation.
The CRA guidance specifically deals with situations where a buyer purchases a home from a builder and may not be a first time home buyer, provided the buyer meets the applicable eligibility rules.
That is why this deserves a new blog post.
The earlier discussion was largely about proposed relief, first time buyer rules, and what was still unknown.
Now we are dealing with a separate enhanced Ontario program that has its own process and interaction with existing rebates.
If you are not a first time home buyer, do not automatically assume you are out.
Review the rules properly.
Does This Apply To Resale Homes?
No.
This applies to qualifying newly built or substantially renovated homes.
It does not apply to a standard resale home.
So if you are comparing resale homes against new construction, this rebate could change the math.
But it does not automatically make every new build a great deal.
That is another trap.
A rebate can improve the numbers, but it does not replace due diligence.
You still need to look at:
Location
Builder reputation
Deposit structure
Closing timeline
Upgrade costs
Assignment rules
Comparable resale values
Future resale demand
Monthly carrying cost
Whether the home actually fits your life
A bad deal with a rebate can still be a bad deal.
A good deal with a rebate can become a very strong opportunity.
That is the difference.
Why This Matters In Ottawa
Ottawa has a lot of new construction options.
Suburbs.
Infill.
Towns.
Singles.
Low rise projects.
Higher end builder inventory.
The enhanced new home HST rebate could make certain new build purchases more attractive, especially for buyers who were close on affordability or comparing builder inventory against resale homes.
But the market will adjust.
Builders may change pricing.
Demand may increase.
Inventory may move faster.
Some buyers will misunderstand the rebate.
Some buyers will assume they qualify when they do not.
Some buyers will miss the opportunity because they wait too long.
That is why this is not something to casually ignore.
What I Would Do Before Signing A New Build Agreement
Before signing a builder agreement, I would want clarity on:
The full purchase price
Whether HST is included or added on top
Whether the home is expected to qualify
Whether the builder is applying the rebate credit at closing
The exact rebate assignment process
The required forms
The closing adjustment structure
The deposit structure
Upgrade pricing
Whether the home makes sense without relying blindly on the rebate
That last point matters.
Do not buy something just because there is a rebate.
Buy the right property, with the right numbers, in the right location, with the right strategy.
The rebate should improve the deal.
It should not be the only reason you do the deal.
Final Thoughts
The Ontario new home HST rebate is now a much bigger conversation than it was a few months ago.
This is no longer just a proposed change buried in government announcements.
The enhanced program is here, the CRA has issued guidance, and buyers looking at new construction need to understand how it works.
The opportunity is real.
But so is the fine print.
If you are buying a new build in Ottawa, do not assume the headline number tells the whole story.
Understand the math.
Understand the eligibility.
Understand the builder process.
Understand what happens at closing.
Then make your decision.
Before you sign a new build agreement, run the numbers first:

This is a limited time opportunity.
Do not sleep on it.
