HST Rebates: Federal GST and Provincial Relief

Policy Overview, Financial Impact, and What It Means for Buyers

Introduction

A new federal GST rebate, combined with proposed provincial changes in Ontario, could significantly reduce the cost of buying a newly built home for first-time home buyers in Canada.

For eligible buyers, total potential tax savings could reach up to $130,000.

For many first-time home buyers, affordability is not defined by home prices alone.

Closing costs, taxes, and upfront cash requirements often determine whether a purchase is feasible.

One of the most persistent cost barriers in new construction has been sales tax. In Ontario, this takes the form of the Harmonized Sales Tax (HST), which combines both federal and provincial components.

Recent policy announcements at both levels of government signal a meaningful shift in how these costs may be addressed.

Policy Overview

Before reviewing the proposed changes, it is important to understand how sales tax applies to new homes in Ontario.

How HST Applies to New Homes in Ontario

In Ontario, newly constructed homes are subject to a 13% Harmonized Sales Tax (HST).

This tax consists of:

• 5% federal portion (GST)
• 8% provincial portion

Although paid as a single tax, these components are administered separately by federal and provincial governments. As a result, any rebates or policy changes are also structured at these two levels.

Recent Policy Changes

Recent announcements from both the federal and Ontario governments aim to reduce the impact of sales tax on new home buyers.

• The Federal Government has introduced enhanced GST relief targeted at first-time buyers, reducing or eliminating the 5% federal portion within defined price thresholds
• The Ontario Government has announced plans to expand relief on the 8% provincial portion of HST for eligible buyers
  

According to the Ontario 2026 budget and official release, the province’s objective is to significantly reduce the provincial portion of HST, with total combined relief potentially reaching up to $130,000 per home when aligned with federal measures.

However, full removal of the 13% HST depends on federal participation, as the federal government must legislate changes to the 5% GST portion.

Financial Impact

From a financial perspective, the proposed changes could materially reduce the cost of purchasing a newly built home.

Because HST consists of both federal and provincial components, the financial impact should be evaluated in two parts.

Federal GST Savings (5%)

The enhanced federal rebate targets the 5% GST portion of HST for first-time buyers.

Potential savings include:

• ~$25,000 on a $500,000 home
• ~$37,500 on a $750,000 home
• Up to ~$50,000 on a $1,000,000 home

Savings gradually decrease for homes priced between $1,000,000 and $1,500,000, with no rebate available above that range.

Ontario HST Savings (8% – Proposed Expansion)

Ontario’s proposal focuses on the 8% provincial portion of HST.

If implemented as outlined in the 2026 budget:

• ~$40,000 on a $500,000 home
• ~$60,000 on a $750,000 home
• ~$80,000 on a $1,000,000 home
  

Relief is intended to be maintained, with adjustments, for homes priced up to $1,500,000.

Combined Impact

When both federal and provincial measures apply:

• Total tax savings could reach up to $130,000 on a $1,000,000 home
• The upfront cash required at closing may be significantly reduced
• The cost gap between new construction and resale homes may narrow

However, it is important to note that:

• The federal portion depends on eligibility criteria for first-time buyers
• The provincial expansion is based on current policy direction and subject to final implementation

By comparison, the existing GST New Housing Rebate provides a maximum federal recovery of approximately $6,300, which has limited impact at current price levels.

Eligibility Framework

Eligibility for tax relief on new homes is determined separately at the federal and provincial levels.

As a result, buyers should evaluate each component independently.

Federal Eligibility (First-Time Buyers)

The enhanced GST rebate is specifically targeted at first-time home buyers.

While final administration is expected through the Canada Revenue Agency, the general criteria include:

• Buyer must qualify as a first-time home buyer (typically defined as not owning a principal residence in the past four years)
• Property must be intended as a primary residence
• Buyer must be:
  • At least 18 years of age
  • A Canadian citizen or permanent resident
• In joint purchases, all buyers must meet eligibility requirements
  

This program is designed to support owner-occupiers entering the housing market, rather than investors.

Ontario Eligibility (Eligible Buyers)

Ontario’s proposal refers to “eligible buyers”, which is broader than the federal first-time buyer definition.

Based on the existing housing rebate framework, this generally includes:

• Individuals purchasing a newly constructed or substantially renovated home
• Buyers intending to:
  • Occupy the property as a primary residence, or
    
  • Use it as a long-term rental property
    

This suggests that eligibility may extend beyond first-time buyers to include existing homeowners and certain investors.

However, as with other elements of the policy, final eligibility rules will depend on implementation details.

Combined Eligibility Considerations

When evaluating eligibility across both programs:

• Federal and provincial requirements may differ
• Not all buyers will qualify for both components
• The structure of the purchase (e.g., personal vs corporate ownership) may affect eligibility
• Builder pricing may assume rebate eligibility when advertising “HST included” homes
  

As a result, buyers should assess eligibility carefully to understand the actual tax payable at closing.

Market Implications

The proposed changes may influence both buyer behavior and demand for new construction. Key implications include:

• Improved competitiveness of new homes relative to resale properties, as the HST cost gap narrows
• Lower upfront costs, reducing cash required at closing and improving affordability for some buyers
• Demand timing effects, with early buyers potentially benefiting from better inventory and negotiation conditions
• Increased demand in key price segments, particularly where tax savings are most significant
  Overall, these changes may support stronger demand for new construction, depending on final implementation and broader market conditions.

Limitations and Considerations

While the policy direction is clear, several elements remain subject to final legislative and administrative details.

• Federal participation is required to fully eliminate the 5% GST portion
• Ontario’s expanded rebate structure is based on current budget direction and subject to final implementation
• Eligibility requirements may differ between federal and provincial programs
• Application and administration will be handled through existing CRA processes
  
• Builder pricing may assume rebate eligibility, which can affect final costs if criteria are not met
  

As a result, buyers should treat projected tax savings as indicative rather than guaranteed, and evaluate their specific eligibility before making purchase decisions.

Conclusion

The expansion of GST relief, combined with Ontario’s proposed HST changes, introduces a meaningful shift in how new construction is priced and evaluated.

For eligible buyers, these measures can materially reduce upfront costs and improve overall affordability. At the same time, the full impact will depend on final implementation and individual eligibility.

For those evaluating their options, this introduces an important new variable — one that may influence both timing and property selection decisions in the months ahead. If you’re starting your home buying journey, you can explore our complete guide for first-time home buyers in Canada.
