🏡 HST Rebates for Custom-Built Homes in Ontario — How RebateMax Helps You Get Thousands Back

Building your dream home in Ontario? You could be eligible for up to $24,000 in HST rebates through the federal and provincial new housing rebate programs. At RebateMax, we specialize in helping homeowners, builders, and owner-builders recover the maximum rebate possible — even if your build is already complete.

💡 What Is the HST Rebate for Custom-Built Homes?

When you build your own home, buy a newly constructed one, or hire a builder to complete it, you pay Harmonized Sales Tax (HST) on many of your costs — materials, labor, and land (in some cases).

The Canada Revenue Agency (CRA) allows you to claim back a portion of that HST through the New Housing Rebate (NHR) program. This applies to:

Owner-built custom homes
Modular or prefab homes
Substantial renovations (major remodels that affect most of the structure)
Laneway homes, garden suites, and secondary units

If your home is your primary place of residence, you may qualify for a rebate of up to $24,000.

🧾 Who Qualifies for the Custom Home Rebate?

To be eligible for the HST New Housing Rebate, you must meet the following criteria:

The home must be newly built or substantially renovated.
You must own or lease the land where the home sits.
The home must be your primary residence (or that of an immediate family member).
You must have paid HST on materials, contractor invoices, or land.
The application must be submitted within 2 years of occupancy.

👉 Even if your home was completed up to two years ago, RebateMax can still help you claim your rebate.

💰 How Much Can You Get Back?

The rebate amount depends on your total spend and the purchase price (for builder-built homes).

For custom builds and owner-built homes, you can typically recover a portion of the HST paid on materials and labor.
The maximum rebate for a primary residence is approximately $24,000.
For substantial renovations, $16,080

RebateMax ensures you don’t leave money on the table — we handle all the forms, receipts, and CRA documentation.

⚙️ How RebateMax Makes It Easy

Filing your HST rebate can be confusing — the CRA requires precise documentation, proof of occupancy, and detailed cost breakdowns.

That’s where RebateMax comes in:
✅ We review your invoices and receipts
✅ Prepare all CRA rebate forms
✅ Submit your application correctly
✅ Follow up with the CRA until your rebate is processed

And best of all — we work on a success-fee basis. You don’t pay us unless your rebate is approved.

⏳ Don’t Miss Your Deadline

If your home was completed within the last two years, you’re still eligible to apply. After that, the rebate window closes permanently.

Many homeowners don’t realize they qualify — until it’s too late. RebateMax specializes in retroactive HST rebates, so even if your project finished months ago, you could still receive thousands back.
