Buying a first home is already document-heavy. When the home is newly built or substantially renovated, GST/HST rebate rules can add another layer of confusion before closing.

For eligible first-time buyers in Ontario, rebate programs can create meaningful savings. But the details matter. Buyers should understand which rebate is being credited, whether the builder is applying for it, whether the purchase price assumes the rebate will be assigned, and what happens if the buyer later turns out not to qualify.

The issue is not only whether a rebate exists. The issue is how the rebate is handled in the agreement, the statement of adjustments, the closing funds, and the paperwork signed before title transfers.

A careful review before signing or closing can help buyers avoid surprises at the moment when the financial pressure is highest.

New-home rebates are not the same as resale-home benefits

GST/HST new housing rebates generally apply to new or substantially renovated homes, not ordinary resale homes. For first-time buyers in Ontario, the relevant rebate conversation often comes up when purchasing a newly built house, townhouse, condo unit, mobile home, floating home, or certain co-op interests.

That distinction matters because many first-time buyers hear the word “rebate” and assume it applies to any first home. It does not.

A buyer purchasing a resale home may have other closing-cost issues to consider, such as land transfer tax and financing adjustments. A buyer purchasing from a builder may also have GST/HST, new housing rebates, builder credits, occupancy costs, development charges, upgrades, and assignment issues to review.

Before signing, buyers should confirm whether the transaction is actually eligible for a GST/HST new housing rebate and whether the rebate is already built into the advertised price.

What the first-time home buyer GST/HST rebate can do

The federal first-time home buyers’ GST/HST rebate is designed to reduce the federal portion of GST/HST payable on qualifying new or substantially renovated homes.

For eligible first-time buyers, the rebate can provide 100% of the GST, or federal part of the HST, on a qualifying new home valued up to $1 million. The rebate is reduced for homes valued between $1 million and $1.5 million, with no federal first-time home buyers’ rebate available at $1.5 million or more.

Ontario buyers may also be eligible for relief on the provincial part of the HST. The Ontario first-time home buyers’ rebate provides a rebate of up to $80,000 of the provincial part of the HST and follows the federal eligibility conditions.

The savings can be significant. But the buyer should not treat the rebate as automatic. Eligibility, timing, paperwork, purchase structure, and closing documents all matter.

Eligibility should be checked early

The first-time buyer test is more specific than many buyers expect.

Generally, a buyer must be at least 18 years old, be a Canadian citizen or permanent resident, and not have lived in a home that they or their spouse or common-law partner owned as a primary place of residence during the relevant period.

The spouse or common-law partner issue is important. A buyer may think of themselves as a first-time buyer because they personally have never owned a home. The rules may look at whether the buyer’s spouse or common-law partner owned and occupied a home during the relevant period.

There are also property-related conditions. The home must generally be acquired or built for use as the buyer’s primary place of residence. The buyer must also meet timing requirements, and in many builder purchase situations, the buyer must be the first individual to occupy the home after construction or substantial renovation is completed.

These details should be confirmed before the buyer relies on the rebate in their closing budget.

Builder credits can change the cash needed on closing

In many new-home purchases, the agreement assumes that the buyer will assign the rebate to the builder. In exchange, the builder may credit the rebate against the purchase price or total amount payable.

This can reduce the amount the buyer needs to bring to closing. But it also means the buyer is usually making representations about eligibility. If the buyer does not qualify, the buyer may be responsible for paying back the amount that was credited.

The agreement of purchase and sale should be reviewed for language about:

• whether the purchase price is inclusive of HST;
• whether the rebate has already been factored into the price;
• whether the rebate is assigned to the builder;
• what forms the buyer must sign;
• what happens if the buyer is not eligible;
• whether the buyer must occupy the home as a primary residence;
• whether the buyer must reimburse the builder if the rebate is denied.

A rebate credit is helpful only if the buyer understands the conditions attached to it.

When buyers may need to apply themselves

Not every rebate is handled the same way. If the builder pays or credits the rebate to the buyer, the builder must submit the rebate application to the CRA. If the builder does not pay or credit the rebate, the buyer generally must submit the application directly.

That distinction matters for cash flow.

If the rebate is credited on closing, the buyer may need less money upfront. If the rebate is not credited, the buyer may have to pay the tax amount first and then apply for the rebate later, subject to eligibility and filing deadlines.

Buyers should not wait until the day before closing to find out which situation applies. They should ask their real estate lawyer to review the agreement, builder documents, and statement of adjustments to confirm how the rebate is being treated.

Assignments can complicate rebate eligibility

Assignment purchases can create extra rebate issues. This is common where an original purchaser signs an agreement with a builder and later assigns that agreement to a new buyer before closing.

The assignee buyer may still be able to qualify for a GST/HST new housing rebate if the legal requirements are met. But assignment transactions can be more complicated because the buyer may be dealing with both the original builder and the assignor.

The assigned agreement may also affect the purchase price, tax calculation, rebate eligibility, and closing documents. In some cases, GST/HST may apply to the assignment amount or to the sale of the interest in the property.

Buyers should review:

• the original agreement date;
• the assignment agreement date;
• the assignment price;
• whether GST/HST applies to the assignment;
• whether the buyer will be the first occupant;
• whether the buyer will use the home as a primary residence;
• whether the builder will credit any rebate;
• whether the assignor has made promises about rebates that the builder or CRA may not accept.

This is an area where assumptions can become expensive. A buyer should have the assignment reviewed before signing, not only before closing.

The purchase price may already assume the rebate

One of the most common points of confusion is whether the listed price already includes the rebate.

Some builder agreements show a price that assumes the buyer will assign the rebate to the builder. The buyer may believe they are receiving an additional rebate after closing, when the rebate has already been used to reduce the price.

Other agreements may require the buyer to pay the full HST-inclusive amount and apply for the rebate directly.

The difference affects closing funds. It can also affect whether the buyer has enough mortgage financing and cash available to complete the transaction.

Before signing, buyers should ask for a clear explanation of:

• the base purchase price;
• HST included or payable;
• rebates credited by the builder;
• rebates the buyer must apply for directly;
• adjustments due on closing;
• deposits already paid;
• development charges or capped charges;
• occupancy fees for new condos;
• upgrade costs and taxes.

The numbers should be clear before the buyer commits.

Rebate forms should not be treated as routine paperwork

Closing documents can move quickly. Buyers may be asked to sign forms confirming that they qualify for a rebate, intend to occupy the home, and will comply with program requirements.

Those forms should be read carefully.

If a buyer signs rebate forms that do not match the facts, problems may follow. For example, the buyer may be purchasing for a parent, child, investment purpose, short-term rental, resale, or another arrangement that does not fit the primary residence requirement. The buyer may also be closing through an assignment or with a spouse or common-law partner whose ownership history matters.

The safest approach is to clarify eligibility before signing documents that assign the rebate or confirm entitlement.

Closing costs should be reviewed with the rebate in mind

A rebate can reduce the total cost of buying a new home, but it does not eliminate all closing costs.

First-time buyers should still budget for:

• land transfer tax;
• legal fees and disbursements;
• title insurance;
• mortgage costs;
• property tax adjustments;
• utility adjustments;
• development charges or levies;
• Tarion enrolment fees, where applicable;
• occupancy fees for new condos;
• upgrades and extras;
• moving costs;
• insurance;
• potential HST amounts not covered or credited by rebates.

The rebate should be treated as one part of the closing analysis, not a replacement for a full closing-cost review.

Keep records after closing

Buyers should keep copies of all rebate-related documents after closing. That includes the agreement of purchase and sale, amendments, assignment agreement if applicable, statement of adjustments, builder invoices, HST calculations, rebate forms, occupancy documents, proof of primary residence, and correspondence about the rebate.

These records can matter if the CRA asks questions, if the builder’s calculation is disputed, or if the buyer later needs to confirm how the rebate was handled.

A clean file can also help if there are post-closing issues with the builder, assignment, occupancy, or tax treatment.

One high-impact list: what buyers should review before signing or closing

Before relying on a GST/HST rebate, first-time buyers in Ontario should clarify:

• Is the home new or substantially renovated, or is it a resale home?
• Does the purchase qualify for the federal first-time home buyers’ GST/HST rebate?
• Does the purchase qualify for the Ontario first-time home buyers’ rebate?
• Is the buyer eligible based on ownership history, spouse or common-law partner history, citizenship or residency, and primary residence use?
• Is the purchase price HST-inclusive?
• Has the builder already credited the rebate in the price?
• Is the buyer assigning the rebate to the builder?
• If the builder is not crediting the rebate, does the buyer need to apply directly?
• What forms must be signed before closing?
• Is the transaction an assignment, and does the original agreement date create a problem?
• Will the buyer be the first individual to occupy the home?
• What happens if the rebate is denied after closing?

A practical way to protect the rebate before closing

GST/HST rebates can create real savings for first-time buyers in Ontario, but they should not be treated as automatic money back. The agreement, assignment terms, builder credit, eligibility rules, and closing adjustments all need to line up.

The best time to review those details is before signing or closing. Once the deal is firm, it may be harder to fix rebate assumptions that were built into the price, financing, or closing funds.

FAQs — Ontario First-Time Home Buyer GST/HST Rebates

What is the Ontario first-time home buyer GST/HST rebate?

For eligible first-time buyers purchasing a new or substantially renovated home, GST/HST rebate programs may reduce the federal and provincial parts of the HST. The federal rebate can apply to the GST or federal part of the HST, while the Ontario first-time home buyers’ rebate can apply to part of the provincial HST.

Who qualifies as a first-time home buyer for the GST/HST rebate?

Eligibility depends on several factors, including age, Canadian citizenship or permanent resident status, ownership history, spouse or common-law partner ownership history, previous rebate claims, timing, and whether the home is acquired for use as a primary place of residence.

Does the builder apply for the GST/HST rebate?

If the builder pays or credits the rebate to the buyer, the builder must submit the application. If the builder does not pay or credit the rebate, the buyer generally must apply directly within the applicable deadline.

What does it mean to assign the rebate to the builder?

Assigning the rebate means the buyer allows the builder to receive or claim the rebate amount, often in exchange for a credit against the purchase price or amount due on closing. Buyers should understand what they are signing and what happens if they are later found not to qualify.

Can an assignment purchase qualify for a rebate?

It may, but assignment purchases can be more complicated. The original agreement date, assignment agreement, tax treatment, first occupancy, primary residence use, and rebate eligibility should all be reviewed before the buyer relies on the rebate.

Is the rebate paid to me after closing?

Not always. In many builder transactions, the rebate may already be credited in the purchase price or on closing. If the builder does not credit the rebate, the buyer may need to apply directly and wait for the application to be processed.

What should I review before closing on a new home in Ontario?

Buyers should review the agreement of purchase and sale, rebate assignment language, HST treatment, statement of adjustments, eligibility requirements, assignment documents if applicable, closing costs, occupancy obligations, and whether the buyer or builder is responsible for submitting rebate forms.
