You’re a few weeks from closing. Somewhere in the paperwork, or in a phone call with the sales office, you learn that the HST rebate you’d been counting on isn’t going to be credited against your purchase price. You’ll need to pay the full amount at closing and claim it back from the CRA yourself.
If the number involved is five figures, that is a genuinely alarming sentence to read.
Here’s what’s actually going on, and what it means for you.
First: you have not lost the rebate
This is the part worth saying immediately.
The money is still yours. Nothing about your entitlement has changed. What’s changed is who files the paperwork and when you get paid.
Normally your builder credits the rebate against your purchase price at closing, then recovers it from the CRA themselves. You never see a form and never think about it again. That’s how most people experience this, which is exactly why it’s so unsettling when it doesn’t happen.
The alternative route — you pay the full HST, then apply directly — is a completely normal way for this to work. It’s the only way it works for rental properties, where a builder is not permitted to credit the rebate at all.
You’re now on that route. It’s longer, and it puts the filing on you. But the rebate is intact.
Why this is happening
Three things converged.
The law moved faster than the administration behind it. Ontario’s enhanced rebate went from budget announcement to registered regulation inside a few months. The CRA’s forms and systems took time to catch up — builders can credit, the forms exist, but the ONHAP portion carries a months-long recovery gap tied to verification of your eligibility.
That’s a cash-flow problem at a scale builders haven’t faced before. When the maximum rebate was $24,000, fronting it across a handful of closings was manageable. At up to $130,000 per home, across a whole project, the numbers are different.
And there’s a liability question. When a builder credits a rebate, they’re taking a position on whether you qualify. If it turns out you didn’t, the buyer has to repay it — and where the builder knew or ought to have known the buyer wasn’t entitled, the two of them can be jointly and severally liable.
Ought to have known” is the phrase that matters to a builder, because the first-time buyer test turns on a four-calendar-year ownership lookback that includes the purchaser’s spouse. A builder has no way to verify that. They’re relying on a declaration signed by the person who benefits from the answer.
That matters more than it used to, because the first-time buyer programs turn on a four-calendar-year ownership lookback that includes your spouse’s ownership history. A builder has no way to verify that. They’re relying on a declaration signed by the person who benefits from the answer.
Faced with all three, some builders have concluded that not crediting is the cleaner position. That’s a commercial decision, and it isn’t unreasonable.
What it means for you — three things
- You need the cash at closing. This is the real problem. On a $700,000 new home the full 13% HST comes to roughly $91,000. If you were expecting that to be netted off, your closing costs just changed, and your lender may need to know.
Raise this with your mortgage broker and your lawyer as soon as you know. Not the week of closing. - You become the filer. Forms, supporting documentation, evidence of eligibility, and any CRA review all land on you rather than on the builder. That’s not insurmountable, but it isn’t a form you dash off on a Sunday either — particularly if your circumstances are anything other than straightforward.
- There’s a deadline. For a purchase claim the filing window generally runs two years from the date ownership transferred to you. That sounds like plenty. It isn’t, in practice, because nothing prompts you. There’s no letter from the CRA and no reminder from anyone. People simply forget, and then the window closes.
Before you sign anything
If your builder is amending the agreement — or asking you to sign something new — about who carries the HST at closing, get advice on the wording before you sign, not after.
The language matters. An amendment can be drafted to acknowledge your entitlement and your right to claim, or it can be drafted in a way that muddles it. Fixing that in advance costs a conversation. Fixing it afterwards is considerably harder.
This is worth ten minutes with your lawyer, or with us.
What to do
Confirm what you’re actually entitled to. Three dates settle most of it: when you signed your agreement, when you’re closing, and — if it’s a first-time buyer claim — when you last owned a home you lived in. Those determine which of the current programs apply and what the number is.
Get the closing-cost change in front of your lender early. This is the piece that causes genuine trouble, and it’s the most time-sensitive.
File properly, once. A claim assembled correctly the first time is far less likely to be reviewed, and far better positioned if it is.
Don’t wait. Not because the deadline is imminent, but because the thing that stops people claiming isn’t the deadline — it’s that the file gets put in a drawer and eighteen months pass.
The short version
Your builder declining to credit the rebate is a change in process, not a loss of entitlement. It’s become more common as the amounts involved have grown, and it’s likely to stay common while the administration settles.
What it does mean is that a five-figure sum is now sitting in your hands to claim, with no one prompting you to do it. That’s the part worth acting on.
