Ontario HST Rebate 2026: What's Law and What Isn't
A question I keep getting from Realtors and buyers alike. Here's the honest answer.
I am the person who actually wants to explain the fine print. So when the same question kept landing in my inbox, I decided to put a real answer in writing.
Realtors I work with have been asking. Buyers shopping for new builds have been asking. The question is always some version of this:
"Tipper, is the enhanced HST rebate actually law yet?"
Honest answer? Kind of. There are actually two different rebates floating around right now, and a lot of people are mixing them up. One is fully law and you can plan around it today. The other is announced and coming, but the mechanics are not fully sorted yet.
The gap between those two is where I am seeing buyers get tripped up. They hear "$130,000 in HST savings" and budget like it is all guaranteed. Some of it is. Some of it is not quite there yet.
This post is written so a buyer and a Realtor can both read it and walk away clearer. If you are a buyer, you will see exactly what to ask. If you are a Realtor, you will see how to set expectations early and avoid surprises at closing.
The two HST rebates at a glance. One is law. One is announced but not yet fully operational.
The Two Rebates, Side by Side
Rebate 1: The Federal First-Time Buyer Rebate
Status: In force.
This one is real, in effect, and you can plan around it today.
Bill C-4 received Royal Assent on March 12, 2026. The CRA started accepting applications on March 17. So if you (or your client) are a first-time buyer purchasing a newly built home up to $1.5 million, the rebate is live.
Here's the quick version of how it works:
Homes up to $1 million get the full federal GST or federal portion of HST rebated, which works out to up to $50,000 back.
Between $1 million and $1.5 million, the rebate phases out on a sliding scale.
Above $1.5 million, no federal rebate.
The agreement of purchase and sale needs to be signed on or after March 20, 2025. The home needs to be your primary residence. Standard first-time buyer eligibility applies, meaning neither you nor your spouse can have lived in a home you owned in the current year or the previous four.
If you closed before March 12 (Royal Assent day), the rebate is still available, but you will need to apply directly to the CRA rather than getting it credited at closing through the builder.
That part is settled. Move forward with confidence.
Rebate 2: The Ontario Enhanced Rebate
Status: Announced, but not fully operational.
This is where it gets a bit messier.
In the March 26 provincial budget, Ontario proposed an enhanced rebate that goes well beyond first-time buyers. For one year, from April 1, 2026 to March 31, 2027, the province wants to remove the full 8% provincial portion of HST on new homes for any buyer. That is up to $80,000 in provincial relief on its own.
Combined with the federal piece, eligible buyers could see up to $130,000 in total HST relief. That's the headline everyone is sharing.
Here's the part most articles are skipping. The federal regulations needed to fully bring the provincial component into force are not finalized yet. The implementing amendments to the Excise Tax Act have not been released. That means the forms, the builder credit process, and the exact mechanics of how this gets claimed at closing are still being worked out.
The policy direction is real. The provincial and federal governments have committed to coordinating it. But the operational pieces are not all in place yet.
Resale Homes: Not Eligible
Before we go further, this needs to be clear.
The HST rebate only applies to new builds and substantially renovated homes. If you are buying a resale home, none of this applies to you, because resale homes do not have HST charged on them in the first place.
There are three scenarios where it gets confusing:
Assignment sales. Someone bought a pre-construction home and sold the contract before closing. You are still technically buying from the builder, so HST applies and the rebate may apply. This is not a resale even though it can feel like one.
"Newly renovated" resales. A flipper guts a tired home and sells it as basically new. Most of the time this is still a resale (no HST, no rebate). Only if the renovation meets CRA's substantial renovation definition (roughly 90% or more of the interior removed or replaced) can it be treated as new. This is rare and the CRA scrutinizes it heavily.
Builder-occupied units. Sometimes a builder lives in a unit briefly before selling. Depending on circumstances, this can flip the home from "new" to "resale" status, which removes rebate eligibility.
The simple rule: If you are buying directly from a builder and nobody has lived in it, the rebate conversation is on the table. If you are buying from a previous homeowner who lived in it, no rebate, no matter how new the home looks. If it is an assignment, a renovation, or anything in between, get your lawyer to review the documents before you sign. The HST piece alone can be a $50,000 to $130,000 question.
Why This Distinction Matters
This is where I see people getting tripped up.
A buyer reads a headline that says "$130,000 in HST savings on new homes." They take that number into their planning. They factor it into their offer. They tell their lender to underwrite based on it.
The problem is that some of that $130,000 is locked in and some of it is still being built out. If you sign an agreement assuming the full Ontario piece is automatic, and the rollout works differently than expected, that gap shows up at the worst possible time.
At closing.
I am not saying do not talk about the rebates or do not factor them in. I am saying be precise about which pieces you are actually counting on.
When Do You Actually Get the Money?
This is the part most buyers do not understand until it is almost too late. There are two paths the rebate can take, and which one applies completely changes how much cash you need at closing.
The two paths your HST rebate can take, and what each one means for your cash at closing.
Path 1: Builder Credits the Rebate at Closing
Most major builders do this on standard new builds. The rebate is baked into the purchase price upfront. You sign an assignment of the rebate to the builder, the builder claims it from the CRA after closing, and you never see that money because it never leaves the deal.
What this means for you: Your down payment and mortgage are calculated on the net price. You do not need to bring extra cash. Easy.
Path 2: You Pay the Full HST at Closing and Apply to the CRA After
Some builders will not credit it. Closings that happened before Royal Assent had to go this route. Assignments and renovated properties almost always do.
You bring the full HST to closing on top of your down payment. Then you apply to the CRA and wait.
What this means for you: On an $800,000 condo, that is potentially an extra $104,000 in cash you need at closing. CRA processing typically takes 2 to 6 months, sometimes longer.
The question to ask your builder before you sign: "Are you crediting the GST/HST rebate at closing, or will I need to pay the full HST and apply to CRA myself?" That single question changes how I structure your pre-approval.
What to Do Right Now
If you are a buyer looking at a new build, here is the framework:
1. Figure out if you qualify as a first-time buyer under the federal rules. If yes, the federal rebate is real and you can plan around it. Ask your builder whether they will credit it at closing or whether you will apply directly to the CRA after.
2. Check if your agreement falls in the April 1, 2026 to March 31, 2027 window. If yes, the Ontario enhancement is likely to apply, but treat the exact mechanics as "to be confirmed" until the federal regulations and CRA forms are released.
3. Ask your builder directly how they are handling it. Some builders are out front on this and adjusting their statements of adjustment proactively. Others are waiting until everything is finalized. That inconsistency creates real risk if assumptions get baked in too early.
4. Talk to your mortgage broker before you sign anything. If you are budgeting based on rebate money, your broker can tell you which pieces are safe to count on for your pre-approval and which pieces should be treated as a bonus rather than a baseline.
If you are a Realtor advising clients, the same framework applies, just one level up. Your job is to set the expectation early. Something like, "Here's what's enforceable today. Here's what's announced and likely coming. Here's how we'll structure your offer based on what we actually know." That kind of honesty builds way more trust than promising savings that are not fully in your hands yet.
The Bottom Line
The most important question right now is not "old rebate or new rebate." It is "what is actually law, and what has been announced but is still being finalized?"
The federal piece is law. Plan around it.
The Ontario piece is real and coming, but the mechanics are still being sorted. Talk about it carefully.
The buyers, agents, and brokers who get this distinction right are the ones who avoid surprises at closing. Because at closing, only what is enforceable actually matters.
