HST & A Commercial Real Estate Purchase

Let's Talk Commercial Real Estate!

Let's Talk HST in Commercial Real Estate.

Every HST-registered business understands the basics of HST. You charge it on goods and services you provide (outputs) and you pay it on goods and services you purchase to run your business (input tax credits, or ITCs). Every reporting period, typically quarterly,  you either remit or claim the difference between HST outputs and HST input tax credits. That we all understand. But things can quickly become less clear. To use an example, let’s say a private consulting firm elects to purchase an office building and move away from leasing. For this example, the building purchased costs $2,000,000 and the buyer has some questions related to HST. The questions are as follows:

Question:  Is the sale subject to HST?

Answer:      Yes, it is.

Question: When do I pay the HST?

Answer:     You must self-remit and account for the HST accordingly at that time.

Clearly, my second “answer” does not actually answer your question. The reality of the answer is that you must review your HST tax implications with your accountant. I am a commercial real estate agent, and I don’t give tax advice. What I am outlining here is my understanding of the process and presenting my recommendation, which is that you review this with your accounting professional in order to have the clarity you need. I also recommend that you work with a commercial real estate professional and transact your agreement to purchase on an OREA Commercial Form 500, which incorporates the following clause:

Clause 7 is very clear that the Buyer is responsible for HST. It is equally clear that the Buyer is saving the Seller harm from any HST claims and that both parties, Buyer and Seller, are HST registrants. What the clause does not answer is this: in our $2,000,000 purchase example, when is the $260,000 in HST payable? The clause also states the Seller will not collect the HST—this is important. In most transactions, you pay HST at the time of purchase, however this clause does not require you to pay the HST to the Seller. The government understands that this type of purchase is typically outside of your regular course of business. Based on the business’s flow of outputs and inputs, there would very likely be a large HST Credit owed to you as a result of the purchase. So rather than the business paying out the HST and applying for a large credit due back to the business, the HST on the purchase is self-assessed by the business for its input on your HST reporting period and in turn adjusted accordingly. Keep in mind this is just on paper—you never actually paid the HST, so that is factored into the final calculation. In essence, things wash out based on your current HST reporting period for filing of output and inputs relative to this purchase. Important note: The self-assessment must occur within the business’s next filing period and the property purchased must be for commercial use to apply. 

Now, what would happen if the building being purchased is not 100% commercial use? Let’s say for our example that the purchase price of $2,000,000 includes $500,000 for the market value of a commercial component, but the sale comes with four apartments containing five appliances each. In this instance, the same OREA Form 500 would be used, however, there is no HST payable on the residential component (HST is not collected so unless it was newly created there is no HST Component as HST has not been collected on this portion of the asset), only on the commercial component. The only HST chargeable on the apartment sale would be based upon the value of the appliances included. As that is not part of your business, it would not be part of your input tax credit, as there is no HST on residential real estate. Beyond that, the process is based on the commercial components value within the building being purchased—which must be a fair market and supportable value. This value would be reported through the self-assessment process (As outlined above).

The last comment here to consider—and this is where a discussion with your accountant is highly recommended. That conversation should cover not just HST but a discussion on how you should take title to this property (same company or a HoldCo for this purchase). Should your business buy it or should a separate corporation be formed for this purchase to acquire the asset and in turn register as an HST Registrant for this purchase? When considering future retirement and estate planning, it may be advisable for a corporation to own the building. This way if you ever sell the business, you could still maintain the real estate and have the future buyer as your tenant. There are a host of other considerations, but clearly, the time to review these considerations is before you complete the transaction. Also note that pretty much any reasonable condition can be included in the deal, so if you are not sure who is going to take the title, your business or new corporation can be covered within the structure of the Agreement to Purchase (not uncommon at all). A condition of legal review and/or accountant review is easy enough to put in the deal so that you can have the clarity you need when purchasing. We have clauses we can incorporate into the transaction to assist.

Again, I prefaced this post that I am not qualified to give tax advice, therefore I highly recommend reviewing your situation with a professional accountant. This is their wheelhouse and I always value the input from your team of professionals when discussing a transaction.

I hope you find this information resourceful and as always, welcome the opportunity to Talk Commercial Real Estate!

Policy Aspect

Before Bill 17 (Old Rules)

After Bill 17 (New Rules As Of June 6,2025)

Minor Variances (Setbacks)

All deviations from zoning setbacks required a minor variance application (Committee of Adjustment approval). No automatic tolerance.

Up to 10% reduction in required yard setbacks is allowed as-of-right (no rezoning or minor variance needed) for urban residential lands (outside Greenbelt). Example: A 5 m setback can be 4.5 m (10% less) without a variance.

Development Charge Timing

Development Charges (DCs) were due upon building permit issuance for most projects (only certain rentals/non-profits had installment plans). Interest could accrue on deferred payments.

DC Payment Deferral: Developers can now opt to pay DCs at occupancy rather than at permit for any residential development. Municipalities cannot charge interest on DCs deferred to occupancy for rental housing and institutional projects. This improves cash flow during construction.

Development Charge Credits

DC credits earned by building infrastructure could only offset charges for the same type of service (e.g. a road credit only for road DC fees).

Flexible DC Credits: The Province can merge service categories via regulation, so a credit for one service can apply to other services in that merged group. E.g.: A credit for building a road could offset transit-related DCs.

Reducing/Freezing DC Rates

To reduce a DC rate or pause its indexation, municipalities had to amend the DC by-law, requiring a background study and public process – a lengthy procedure.

Easier DC Reductions: Cities can now reduce DC rates or change indexing without a new background study or public hearings. This means municipalities can more quickly lower or freeze DCs to encourage development.

DC “Frozen” vs. New Rate

If a DC rate was “frozen” at site plan/zoning application, a later drop in the DC rate didn’t benefit the project – the developer still paid the higher frozen rate.

Pay Lower DC Rate: Developers will pay the lower of the frozen DC rate or the current reduced rate if DCs drop during the freeze period. This guarantees you won’t overpay if DC charges are cut mid-project.

Long-Term Care (LTC) Homes

New long-term care facilities were subject to standard DCs (adding to project costs).

DC Exemption for LTC: Developments of buildings intended for long-term care are now fully exempt from development charges, lowering costs for these projects.

Inclusionary Zoning (Affordability)

Some municipalities required >5% affordable units and/or >25-year affordability periods in certain zones, which could hinder project viability.

Caps on Requirements: Provincial regs now cap inclusionary zoning in key transit areas to 5% of units and a 25-year affordability period. Higher local requirements must be brought down, making projects more financially feasible.

Planning Application Requirements

Municipalities often demanded extensive studies (wind, shadow, design, lighting, etc.) before deeming a planning application complete, causing delays and costs.

Standardized & Streamlined: The province will standardize required studies. For example, sun/shadow, wind, urban design, and lighting studies will not be required for a complete application. This cuts red tape and speeds up application processing.

Zoning – Schools in Residential

In some cases, zoning bylaws or official plans prohibited building schools on lands zoned residential, limiting flexibility in community planning.

Schools Allowed: Official plans/zoning can no longer ban schools on urban residential land. This change allows elementary/secondary schools (and related uses) “as-of-right” in residential areas, aiding community development.

Building Code Uniformity

Municipalities (e.g. Toronto) could impose extra construction standards beyond the Ontario Building Code (green standards, etc.), adding cost or complexity.

One Province-wide Standard: Municipalities are now prohibited from setting stricter building or demolition standards than the Ontario Building Code. This ensures one consistent building standard across Ontario, preventing costly local requirements.

How These Changes Benefit Developers and Investors

As-of-Right 10% Variance – Less Red Tape: Small adjustments to building plans (like minor setback reductions) no longer trigger a months-long minor variance process. If your project is within 10% of the required setback, you can proceed without a rezoning or Committee of Adjustment hearing. This saves time and fees, enabling faster project starts. Fewer minor variance applications also mean less uncertainty and carrying costs for projects – a clear win for infill developers and homebuilders.

Development Charge Reforms – Lower Upfront Costs: Perhaps the most impactful changes are to development charges, which can be a significant upfront cost for builders, especially on multi-residential projects. Key benefits include:

  • Pay at Occupancy: Instead of paying tens of thousands (or more) in DCs per unit at permit issuance, residential developers can now defer DC payments until occupancy. This deferral frees up capital during construction and reduces financing burdens – you start generating revenue (occupancy or closing sales) before paying major fees. For multi-family condo projects, this aligns cash outflow with project completion, improving project cash flow and viability.
  • No Interest on Deferrals for Rentals: For rental housing developments (and institutional builds), Bill 17 stops municipalities from charging interest on DCs during the deferral period. Previously, even if a city allowed delayed DC payment, interest could accrue, adding cost. Now, rental developers effectively get an interest-free loan on DCs until occupancy – a significant incentive to build much-needed rental units.
  • Flexible & Lower DCs: Municipalities can react more quickly to market conditions by reducing or freezing DC rates without a lengthy process. If economic conditions call for it, cities could temporarily cut or hold DCs to stimulate development. DC credits are also more useful now – if you front-fund infrastructure (e.g. roads, pipes) for your project, the credits can offset charges in other categories, potentially reducing your overall costs. Additionally, if DC rates are cut by the time your project is ready for permit, you get to pay the lower rate (versus being locked into a higher earlier rate), protecting you from overpaying in a falling DC environment.

A More “Builder-Friendly” Planning Process: Beyond dollars and cents, Bill 17 includes changes that simplify and speed up approvals:

  • Standardized Application Requirements: By removing the need for certain studies (like wind or shadow impact studies) at the initial application stage, the province is cutting down on pre-construction hurdles. This means less money spent on consultants and faster time to get an application deemed complete. In turn, that leads to quicker decisions and shovels in the ground sooner.
  • Consistent Building Standards: Developers will no longer face a patchwork of municipal building requirements exceeding the Ontario Building Code. Bill 17 ensures one uniform building code province-wide. For example, if a city had extra “green” building standards or unique technical demands, those can no longer be enforced through local bylaws. This reduces costs (you only build to one standard – the provincial code) and provides certainty, especially for builders operating across multiple municipalities.
  • Encouraging Community Infrastructure: By allowing schools as-of-right in residential zones, the government has made it easier to integrate schools into new communities or redevelopments. For developers, this could streamline approvals for master-planned communities that include schools, or make zoning more flexible when repurposing lands.

Bottom Line for Developers and Investors

Overall, Bill 17 is designed to expedite development timelines and improve project economics in Ontario’s housing and real estate sector. By reducing procedural delays (like minor variances and excessive studies) and lowering upfront costs (through DC deferrals, credits, and potential rate reductions), the Act creates a more positive, pro-building environment. Developers and investors can expect faster approvals and lower carrying costs, especially for multi-family and rental housing projects that the province is keen to see move forward. In short, Ontario is signaling that it wants to “build faster and smarter,” and Bill 17 provides several new tools and incentives to make that happen.
