Ontario HST Housing Rebate 2026: New Budget Changes, Eligibility, and How to Claim Up to $130,000

Ontario's 2026 Budget dropped one of the most significant housing tax measures in recent memory. The province, in partnership with the federal government, is temporarily expanding the HST new housing rebate to cover all eligible buyers of new homes — not just first-time purchasers. For buyers of homes valued up to $1.5 million, the rebate effectively removes the entire 13% HST, delivering savings of up to $130,000.

This is a one-year window. If you are buying a newly constructed home, building your own, or developing residential rental properties in Ontario, this Accounting Intelligence briefing breaks down exactly what changed, who qualifies, and how to claim every dollar you are owed.

What Changed in the 2026 Ontario Budget

The Ontario government announced on March 25, 2026, that it would expand its HST housing rebate program as a temporary, one-year stimulus measure running from April 1, 2026, to March 31, 2027. The federal government has agreed to cost-share the initiative by covering its 5% portion of the HST, subject to the passage of federal legislation.

Here is what is different from the previous rebate structure:

Before (Fall 2025 rules): The enhanced rebate applied only to first-time homebuyers purchasing new homes under $1 million. The rebate covered only the 8% provincial portion of the HST.

After (April 1, 2026 rules): The rebate now applies to all eligible buyers of new construction — first-time, move-up, downsizers, and investors purchasing residential rental properties. Both the provincial 8% and federal 5% portions of the HST are rebated, and the price threshold has increased to $1.5 million for the maximum rebate.

The government estimates this expanded program will generate approximately 8,000 additional housing starts and support up to 21,000 jobs across Ontario's construction sector. The combined federal-provincial tax relief is projected at nearly $2.2 billion.

HST Rebate Amounts: How Much Can You Save?

The rebate structure is tiered based on the purchase price of the new home:

Home Value	Maximum Rebate	Effective HST Paid
Up to $1,000,000	Up to $130,000 (full 13% HST)	$0
$1,000,001 – $1,500,000	$130,000	Partial HST applies
$1,500,001 – $1,849,999	Decreases proportionally from $130,000	Proportional reduction
$1,850,000 and above	$24,000 maximum	Standard rules apply

For a $900,000 new-build condo or townhouse, the buyer saves approximately $103,540 in HST under this expanded rebate. For a $1.2 million detached new home, the fixed $130,000 rebate brings the effective tax rate down significantly below the standard 13%.

Even for luxury purchasers above $1.85 million, the $24,000 rebate under pre-existing rules remains available — this is unchanged from prior legislation.

Who Is Eligible for the 2026 HST Housing Rebate?

The expanded rebate is broader than any previous version. To qualify, you must meet the following criteria:

Property requirements:

• The home must be newly constructed (new builds, substantial renovations, or conversions from non-residential to residential use)
• The property must be located in Ontario
• The purchase agreement must be signed between April 1, 2026, and March 31, 2027

Buyer requirements:

• The home must be used as a primary place of residence by the buyer or a qualifying relation, OR used as a residential rental property
• There is no first-time buyer restriction — this applies to all eligible purchasers
• Individual buyers, couples, families, and investors purchasing purpose-built rentals all qualify

Construction timeline requirements:

• If the purchase agreement was signed between April 1, 2026, and March 31, 2027: construction must begin on or before December 31, 2028, and be substantially completed by December 31, 2031
• If construction began before March 31, 2026: the purchase agreement must be signed between April 1, 2026, and March 31, 2027, and construction must be substantially completed by December 31, 2029

These timelines are critical. Pre-construction condo buyers in the GTA should pay close attention — your closing date and construction completion date must align with these windows to qualify.

How to Claim the HST Housing Rebate

There are two primary pathways to receive the rebate, depending on how you are acquiring the property.

Path 1: Purchasing from a Builder

In most new home purchases from a builder, the rebate is handled at closing. The process works as follows:

1. The builder includes the HST in the purchase price
2. At closing, the buyer assigns their rebate entitlement to the builder by signing the appropriate assignment forms
3. The builder credits the rebate amount against the purchase price, reducing what the buyer pays at closing
4. The builder then files the rebate claim with the CRA on the buyer's behalf

This is the most common scenario for pre-construction condos, new townhomes, and builder-developed detached homes. Review your Agreement of Purchase and Sale carefully — most builders already include language about HST rebate assignment. With the expanded rebate amounts, the financial impact at closing is substantially larger than under previous rules.

Path 2: Owner-Built Homes or Direct CRA Application

If you built the home yourself, or if the builder did not credit the rebate at closing, you must apply directly to the Canada Revenue Agency:

For homes purchased from a builder:

• File CRA Form GST190 (GST/HST New Housing Rebate Application for Houses Purchased from a Builder)
• Include Form RC7190-ON (Ontario Rebate Schedule)

For owner-built homes:

• File CRA Form GST191 (GST/HST New Housing Rebate Application for Owner-Built Houses)
• Include Form GST191-WS (Construction Summary Worksheet) with all construction invoices and receipts
• Include Form RC7191-ON (Ontario Rebate Schedule)

Application deadline: You generally have two years from the date the home is substantially completed and first occupied to file your rebate application. Do not miss this window — there are no extensions.

Documentation You Should Prepare Now

Whether you are working with a builder or self-building, gather and retain:

• The signed Agreement of Purchase and Sale (with closing date)
• All construction invoices, receipts, and contracts showing HST paid
• Proof of occupancy or tenancy (for rental property claims)
• Builder correspondence confirming the rebate assignment (if applicable)
• Title documents and land transfer records

What Builders and Developers Need to Know

This rebate expansion creates immediate opportunities and compliance obligations for builders:

Pricing strategy: With up to $130,000 in rebate value now flowing through transactions, builders may adjust pricing strategies on inventory and pre-construction launches during the April 2026 to March 2027 window.

Assignment mechanics: Builders who typically assign the rebate at closing will need to update their APS templates and closing documentation to reflect the new maximum amounts and expanded eligibility criteria.

HST remittance: Builders are still required to collect and remit HST on the sale. The rebate is a separate claim process — either assigned to the builder at closing or filed independently by the buyer. Incorrect handling can trigger CRA assessments.

Purpose-built rental: Developers building rental housing now have access to the expanded rebate for units that will be rented to tenants as primary residences. This significantly improves project economics for multi-residential developments.

Strategic Considerations for 2026

The one-year window creates urgency but also opportunity for strategic tax planning. Consider the following:

Timing your purchase: If you are currently in negotiations for a new-build purchase, structuring the agreement signing date to fall within the April 1, 2026, to March 31, 2027, window is essential. Even a few days of timing can mean the difference between a $130,000 rebate and the standard reduced amounts.

Pre-construction vs. ready-to-move: The construction completion timelines (2029 or 2031 depending on when construction began) give pre-construction buyers substantial runway — but verify that your specific project's estimated completion falls within the eligible window.

Rental property investors: The extension of eligibility to residential rental properties opens this rebate to a segment that was previously excluded from the enhanced amounts. Investors building or purchasing new rental units should model the rebate into their cash flow projections.

Interaction with other programs: The HST rebate operates independently from the Land Transfer Tax rebate for first-time buyers and other provincial or federal housing programs. Eligible buyers may be able to stack multiple incentives.

The Bottom Line

Ontario's 2026 HST Housing Rebate expansion is the largest housing tax relief measure the province has introduced in years. The combination of expanded buyer eligibility, increased rebate amounts up to $130,000, federal cost-sharing, and a clear one-year implementation window creates a defined opportunity for homebuyers, self-builders, and residential developers.

The window opens April 1, 2026. The documentation and structuring work should start now.
