GST/HST Self-Assessment on New Condo Closings in Ontario: What Buyers Need to Know

 

Most buyers assume the HST on a new condo is just handled — built into the price, dealt with by the builder. That's true if you're moving in. It's not true if you're renting the unit out, and the difference catches a lot of first-time investors off guard right at closing, which is exactly when a real estate accountant in Toronto and the GTA tends to get the panicked phone call.

Why Investors Get a Different HST Bill Than Everyone Else

Buyers who'll live in the unit qualify for the New Housing Rebate, usually credited directly against the price at closing. Buyers who intend to rent it out don't get that convenience — they have to self-assess and remit the HST to the CRA themselves on closing day, in full, with the builder's price not accounting for it at all. The money is recoverable afterward through the New Residential Rental Property Rebate, but that's a separate application that typically takes a couple of months to come back, which means having real cash on hand at closing that an owner-occupier never needs. Confirming that number well before your closing date is exactly the kind of thing HST and GST filing services in Ontario exist to sort out.

What the Rebate Is Actually Worth

The federal component of the rebate (the GST portion) is capped at roughly $6,000, and Ontario's provincial component adds up to another $24,000 on top — together worth up to about $30,000 back. To qualify, the unit generally needs to be leased for at least one year as a long-term residential rental; short-term or Airbnb-style use typically disqualifies the claim entirely. Get the intent or the lease timing wrong and the CRA can deny the rebate or claw it back later, which is a far worse conversation than confirming eligibility upfront through proper real estate tax planning.

What Changed in 2026

Ontario's 2026 Budget introduced an enhanced HST rebate that applies more broadly than the older rules — covering new condos, townhouses, and rowhouses bought either as a primary residence or as a long-term rental, for agreements signed with a builder between April 1, 2026 and March 31, 2027, with construction required to reach substantial completion by the end of 2029 for rental purchases. Separately, the federal government's enhanced First-Time Home Buyer GST rebate — worth up to $50,000 for agreements signed on or after March 20, 2025 — applies only to primary-residence buyers, not investors, and it's easy to see that number mentioned online and assume it applies to a rental purchase when it doesn't. Sorting out which version actually applies to your closing date is a fast-moving question best run past tax planning in Toronto and the GTA rather than assumed from a headline.

If Your Intent Changes Between Signing and Closing

Plans shift over a multi-year pre-construction timeline — a unit bought as a home sometimes ends up rented, or the reverse. If you originally planned to live in the unit and end up renting it out within the first year, you may have to repay the New Housing Rebate in full, sometimes as much as $30,000, and then potentially refile under the rental rebate instead, provided you meet its separate conditions. The CRA looks at your stated intent at the time of purchase, not just what happens later, which makes documentation the whole ballgame. Investors closing on units in Mississauga, Vaughan, or elsewhere across the GTA who aren't sure which stream they fall into should get it confirmed before closing — it's much easier to fix a filing in advance than to unwind a rebate the CRA has already flagged, which is where CRA audit support comes in if it's already gone sideways.

The Paperwork the CRA Will Actually Ask For

The rental rebate application needs to be backed up with real documents, not just a claim — the signed lease showing at least a one-year term, proof of the HST actually paid at closing, and the closing statement showing the purchase price and rebate calculation. Buyers who fold this into proper bookkeeping in Ontario from the day they close tend to have a far smoother rebate process than those scrambling to locate the lease six months later.

Getting the rebate stream right on a new condo closing — end user versus investor, old rules versus the 2026 enhancement — is a one-time decision with a five-figure difference attached, worth getting confirmed before you sign rather than after the cheque clears.

FAQ

Q1: Do I have to pay HST on a new condo if I'm renting it out instead of living in it?
A1: Yes — as an investor you self-assess and pay the HST to the CRA at closing, then apply separately for the New Residential Rental Property Rebate.

Q2: How much is the HST rebate on a new condo in Ontario?
A2: Up to roughly $6,000 federally and $24,000 provincially, for a total that can reach about $30,000, provided the unit qualifies as a long-term rental.

Q3: What happens if I planned to live in my condo but ended up renting it instead?
A3: You may have to repay the original New Housing Rebate in full and apply instead under the rental property rebate, depending on your timing and documentation.

Q4: Does the new 2026 Ontario HST rebate apply to investors, or only homeowners?
A4: It covers both — agreements signed with a builder between April 1, 2026 and March 31, 2027 can qualify whether the unit is for a primary residence or long-term rental.

Q5: Is the $50,000 first-time buyer GST rebate available to investors?
A5: No — that enhanced federal rebate is for buyers intending to use the unit as their primary residence, not for rental purchases.

Q6: How long do I need to rent out my condo to qualify for the rental rebate?
A6: Generally at least one year as long-term residential use; short-term rentals typically don't qualify.
