Quick high level points discussed in greater detail below:
Ownership Structures: Leverage partnerships for loss flow-through (mind at-risk limits for limited partners), corporations for liability protection and small business deductions (up to $500,000 at reduced rates), or trusts for beneficiary distributions; non-residents benefit from Canadian corporations to avoid branch taxes.
Financing Optimization: Ensure interest deductibility by tying debt to income-producing assets, navigate thin capitalization (1.5:1 debt-to-equity for non-residents) and EIFEL rules (30% cap on net interest, with exemptions for purpose-built rentals and regulated utilities per 2025 updates).
Disposition Planning: Treat gains as capital (50% inclusion rate in 2025, post-deferral of proposed increase) with reserves for deferrals; comply with anti-flipping rules (full taxation within 12 months), BC's new Home Flipping Tax (up to 20% on sales within two years), Underused Housing Tax (1% on vacant properties), and foreign buyer ban (extended to 2027).
Deductions and Incentives: Maximize CCA (4-6% for buildings, 30-50% accelerated for green assets), SR&ED credits (up to 35% refundable, expanded in 2025 to include public corporations and capital expenditures post-Dec 2024), and allocate costs to depreciables.
GST/HST Management: Claim full ITCs and enhanced rebates (100% for qualifying purpose-built rentals starting 2023-2030), with new proposals for full 5% GST rebate on homes up to $1M.
Non-Resident Strategies: Use treaties for reduced withholding (15% on net rents) and section 116 certificates; plan around U.S. estate tax exposures.

The Evolving Tax Environment
What Real Estate Professionals Need to Know in 2025
Governments at federal and provincial levels are prioritizing housing supply while curbing speculation. The foreign ownership ban on residential properties, designed to reduce foreign speculation, remains in effect until January 1, 2027, with exemptions for certain developments. Provincial add-ons, such as Ontario's 25% Non-Resident Speculation Tax and British Columbia's 20% foreign buyer tax, layer on top of standard land transfer taxes, impacting cross-border investments.
Anti-flipping rules continue to deem gains on residential properties sold within 12 months as fully taxable business income, discouraging short-term speculation—though exceptions apply for life events like job relocation or family changes. British Columbia's Home Flipping Tax, effective January 1, 2025, imposes a sliding-scale tax (up to 20% for sales within 365 days, declining to 0% at 730 days) on profits from residential sales within two years of purchase, further emphasizing long-term holding.
The Underused Housing Tax (“UHT”) levies a 1% annual charge on vacant or underused residential properties owned by non-Canadians, with filing obligations extending to certain Canadian entities like corporations and trusts (updated rules as of January 2025). This promotes efficient housing use but adds administrative burdens; failure to file can result in penalties even if no tax is owing.
On a positive note, the capital gains inclusion rate remains at 50% following the government's deferral of proposed increases to January 1, 2026, providing relief for long-term investors. The Lifetime Capital Gains Exemption stands at $1.25 million for qualified small business shares or farm/fishing properties (effective June 25, 2024), offering substantial benefits for eligible dispositions.
Sustainability incentives are expanding, with accelerated capital cost allowance (CCA) for green assets and Scientific Research and Experimental Development (SR&ED) credits rewarding innovation in eco-friendly construction (enhanced in 2025 to include public corporations and capital expenditures after December 16, 2024).

Optimizing Ownership Structures: Building a Tax-Efficient Foundation
Choosing the right entity is foundational for tax efficiency, liability protection, and operational flexibility in real estate ventures. For joint developments, co-ownership allows independent tax positions, enabling separate CCA claims without grouping risks—ideal for partners with varying strategies.
Partnerships facilitate direct flow-through of income and losses to partners, which is particularly valuable in early-stage projects with potential losses. However, at-risk rules limit deductions for limited partners to their invested capital, and negative adjusted cost bases can trigger immediate gains. Specified Investment Flow-Through (SIFT) rules may impose corporate-level taxes on publicly traded partnerships with high non-resident ownership.
Corporations provide full liability protection and access to the small business deduction, reducing federal taxes on the first $500,000 of active business income to as low as 9%. Unlimited liability corporations (ULCs) offer hybrid benefits for U.S. investors under tax treaties, minimizing withholding taxes.
Trusts enable flow-through to beneficiaries without entity-level taxation but require caution with distributions to non-residents (subject to Part XII.2 taxes) and alternative minimum tax implications. Bare trusts simplify holding but must be structured to avoid unintended tax triggers.
For non-resident investors, Canadian corporations can sidestep the 35% branch tax on after-tax profits and reduce withholding on rents to 15% via treaty elections for net taxation.
To illustrate, consider a multi-unit rental project: A limited partnership might suit Canadian partners sharing losses, while a corporation could better protect foreign investors. The table below compares key structures to help you evaluate options.
Ownership Structure Comparison
| Structure | Tax Flow-Through | Liability Protection | Key Considerations | Suitability |
|---|---|---|---|---|
| Co-ownership | Yes (independent) | Limited | Separate CCA; minimal grouping risks | Joint developments with individualized planning |
| Partnership | Yes | Limited for general; full for limited | Loss flow-through; at-risk limits; negative ACB triggers gains | Collaborative projects sharing risks |
| Corporation | No (entity-level) | Full | Small business deduction; thin cap rules | Scaled operations; SR&ED refunds |
| Trust | Yes (to beneficiaries) | Varies | Part XII.2 on non-residents; AMT implications | Holding or estate planning |

Smart Financing Approaches
Financing is the lifeblood of real estate and construction, and tax-smart borrowing can enhance returns. Always link debt to income-producing activities to ensure interest deductibility, as upheld in cases like Singleton. Prepayment penalties are generally deductible, and borrowing costs can be amortized over up to five years.
Watch thin capitalization rules, which cap debt-to-equity at 1.5:1 for non-resident financing—excess interest is recharacterized as non-deductible dividends. The Excessive Interest and Financing Expenses Limitation (“EIFEL”) rules, in force for tax years beginning after September 30, 2023 (with 2025 draft exemptions for regulated energy utilities), generally limit net interest to 30% of adjusted taxable income (i.e., tax EBITDA), with carryforwards for excesses. Exemptions apply for de minimis cases ($1 million net expenses) and purpose-built rentals (e.g., projects with at least four units, construction starting 2024-2030, available by 2036), supporting affordable housing initiatives.
For example, isolating rental projects in separate entities can maximize EIFEL exemptions, preserving deductibility. Vacant land rules further restrict interest deductions to a $1 million base plus net income, emphasizing the need for strategic planning.

Disposition and Compliance Planning
Effective disposition planning minimizes taxes on sales. Characterize gains as capital to benefit from the 50% inclusion rate (deferred increase to 2026), with reserves deferring recognition over five years for unpaid proceeds. The doctrine of secondary intention scrutinizes intent: Investment holdings qualify for capital treatment, while inventory-like flips may be taxed as income.
Non-residents face 25% withholding on gross proceeds reducible via tax treaties and section 116 certificates. Changes in use, from personal to rental, trigger deemed dispositions at fair market value, but elections can defer taxes.
Leveraging Deductions and Incentives
Maximize deductions by allocating acquisition costs to depreciable assets like buildings (4-6% CCA under Class 1) over non-depreciable land. Soft costs, interest, taxes, and fees are capitalized until 90% occupancy or income generation, then deductible against net rental income to avoid artificial losses.
Green incentives accelerate CCA: Classes 43.1 (30%) and 43.2 (50%) cover solar, wind, geothermal, and EV charging equipment, aligning with sustainability goals. Construction firms can claim SR&ED credits up to 35% on innovative R&D (expanded in 2025 draft legislation to include public corporations and capital/lease costs after December 16, 2024), such as advanced building techniques.
GST/HST Management: Reclaiming Costs in Development and Sales
Registering for GST/HST unlocks input tax credits (ITCs) on development expenses, a must for commercial and construction activities. New or renovated residential properties trigger self-supply at fair market value, but rebates offset this: The enhanced rebate for purpose-built rentals offers 100% on federal GST for qualifying projects (construction starting September 2023 to December 2030).
For new homes, the federal rebate provides 36% of GST (up to $6,300) for properties under $350,000, phasing out to $450,000, with 2025 proposals for a full 5% rebate on homes up to $1 million (phase-outs apply), aiding first-time buyers and developers.
Provincial variations, like B.C.'s transitional rebates for legacy contracts, add complexity in non-HST provinces. Commercial supplies are fully taxable with ITCs, while residential rentals are exempt.
Tenant and Leasing Dynamics
Leases offer planning opportunities: Tenant inducements (e.g., free rent or improvements) are deductible over the lease term for landlords and income to tenants. Stepped rents accrue evenly for tax, while percentage rents tie to sales. Lease cancellations allow deductions under sections 20(1)(z) and (z.1).
Beware shareholder benefits if corporate tenants fund personal enhancements, triggering inclusions. For real estate pros, structuring leases to align with tax goals can enhance net returns, reach out at dave@venter.ca to explore strategies.
Non-Resident Investments
Non-residents can use Canadian corporations to avoid branch taxes and elect net taxation on rents at graduated rates (often 15% via treaties). Dispositions require section 116 compliance to reduce 25% withholding. U.S. investors benefit from spousal ownership or trusts to minimize estate taxes on vacation properties.
With the foreign buyer ban extended to 2027, advance planning is essential. Venter Accounting & Tax, please reach out to dave@venter.ca to find out more details.
