Every dental practice owner in Canada faces the same decision at least once a year: should you lease that new digital scanner, CBCT unit, or dental chair — or buy it outright? As of September 2026, the answer depends on your practice's cash position, tax structure, growth trajectory, and how quickly the equipment will become obsolete. This guide walks through the financial framework, Canadian tax implications, and decision criteria that matter.
The lease-versus-purchase decision is not simply about monthly payments versus a lump sum. It is a tax planning question, a cash flow management question, and a strategic question about where your practice is heading over the next three to five years. Getting it wrong means either overpaying in interest and fees or tying up capital that your practice needs for growth.
The Two Paths: How Each Works in Canada
Purchasing (Owning the Equipment)
When you purchase dental equipment outright or through a traditional bank loan, your practice owns the asset. Under Canadian tax law, you claim the cost of that asset over time through Capital Cost Allowance (CCA) — the Canadian equivalent of depreciation for tax purposes.
Most dental equipment falls into CCA Class 8, which carries a 20% declining balance rate. This means you deduct 20% of the remaining undepreciated capital cost (UCC) each year. The deduction decreases over time as the UCC shrinks — you never fully deduct the asset in a single year.
Key tax rules for purchases:
- Half-year rule: In the year you acquire the equipment, you can only claim CCA on 50% of the net addition to the class. For a Class 8 asset, this means your first-year deduction is effectively 10% of cost rather than the full 20%.
- Accelerated Investment Incentive: According to Canada.ca, the Accelerated Investment Incentive was reinstated in March 2026 for property acquired after 2024. This incentive can enhance the first-year CCA deduction, potentially allowing a larger upfront write-off. Consult your accountant to confirm eligibility for your specific purchase.
- Interest on financing: If you finance the purchase with a loan, the interest is deductible as a business expense, separate from the CCA deduction on the equipment itself.
Leasing
When you lease dental equipment, the leasing company owns the asset. Your practice makes regular lease payments, which are generally deductible as operating expenses in the year they are made — a straightforward deduction with no CCA calculations, no half-year rule, and no declining balance tracking.
Key tax and financial characteristics of leasing:
- Fully deductible payments: Lease payments are typically deductible as business expenses, providing a consistent, predictable tax deduction each month or quarter.
- No capital outlay: Leasing preserves your practice's cash and borrowing capacity for other needs — renovations, hiring, working capital, or expansion.
- End-of-lease options: Most dental equipment leases offer a buyout at the end of the term (typically $1 buyout, fair market value, or 10% of original cost). A $1 buyout lease is functionally a financing arrangement — the CRA may reclassify it, so structure matters.
- GST/HST on payments: Lease payments are subject to HST in Ontario (13%). You can claim the HST paid as an Input Tax Credit (ITC) if your practice is registered for HST, which most are.
When Leasing Makes More Sense
Leasing is typically the stronger choice in these scenarios:
1. Technology That Evolves Rapidly
Intraoral scanners, CAD/CAM units, and practice management software-driven hardware change significantly every three to five years. Purchasing a $50,000 CAD scanner outright creates a depreciation anchor — you own an asset that may be functionally obsolete before its CCA class is fully depreciated. A lease allows you to upgrade at the end of the term without carrying an outdated asset on your books.
Pro Tip: For any piece of dental technology where the manufacturer releases a meaningfully improved version every 3 to 4 years, a lease term matched to that upgrade cycle (36 to 48 months) keeps your practice on current technology without the pain of selling or writing off a purchased unit.
2. Cash-Constrained or Growing Practices
A practice in its first five years, a practice expanding to a second location, or a practice that has just completed a major renovation may not have the liquidity to tie up $80,000 to $200,000 CAD in equipment purchases. Leasing preserves cash for operating expenses, hiring, and marketing — expenditures that generate near-term revenue growth.
3. Tax Smoothing
Lease payments create a consistent, predictable deduction each month. For practices with stable revenue, this simplifies tax planning. The declining-balance CCA deduction on a purchased asset, by contrast, is front-loaded in theory but limited by the half-year rule in Year 1, then shrinks annually — making tax planning less predictable.
When Purchasing Makes More Sense
Purchasing is typically the stronger choice in these scenarios:
1. Equipment with a Long Useful Life
Dental chairs, cabinetry, compressors, and sterilizers can last 15 to 25 years with proper maintenance. These are assets that do not become obsolete — a quality dental chair from 2026 will function identically in 2041. Purchasing avoids the cumulative interest cost that a lease embeds in its payments, and the practice builds equity in a tangible asset.
2. Strong Cash Position
An established practice with healthy reserves, low debt, and no imminent capital needs may benefit from purchasing outright. The total cost of ownership is lower (no lease interest), the CCA deduction still provides tax benefits, and the practice's balance sheet strengthens with additional asset value.
3. The Accelerated Investment Incentive
With the Accelerated Investment Incentive reinstated for property acquired after 2024 (confirmed March 2026), purchasing certain equipment may yield a larger first-year CCA deduction than in previous years. This incentive can meaningfully accelerate the tax benefit of a purchase, narrowing the gap between lease deductions and CCA deductions in the early years. Confirm specific eligibility with your accountant, as the incentive's rates and qualifying criteria can change.
The Blended Approach: Most Practices Use Both
Experienced practice owners rarely commit to an all-lease or all-purchase strategy. The most common approach is to purchase long-life equipment (chairs, cabinetry, autoclaves) and lease rapidly evolving technology (scanners, imaging systems, CAD/CAM). This blended strategy balances total cost of ownership against technology obsolescence risk.
A typical equipment portfolio for a general practice might look like this:
- Purchase: Dental chairs, cabinetry, compressor, vacuum system, autoclave, handpieces
- Lease: CBCT unit, intraoral scanner, CAD/CAM milling unit, practice management hardware
- Evaluate case-by-case: Laser units, 3D printers, digital radiography sensors
Five Questions to Ask Before You Sign
Whether you are evaluating a lease or a purchase, run through these five questions:
- What is the equipment's useful life versus its technology cycle? If the useful life significantly exceeds the technology cycle (e.g., a scanner that works for 10 years but is outclassed in 4), leasing is safer.
- What are the total payments over the lease term versus the purchase price plus financing cost? Include the buyout amount. A 60-month lease at $1,200/month plus a 10% buyout on a $50,000 asset totals $77,000 — well above the purchase price.
- What is the end-of-lease buyout structure? A $1 buyout lease is effectively a financing arrangement and may be reclassified by the CRA for tax purposes. Fair market value buyouts give you genuine flexibility to walk away from obsolete equipment.
- What is your marginal corporate tax rate? Ontario dental professional corporations currently face a blended federal-provincial rate. Higher marginal rates amplify the value of early deductions — making lease deductions (immediate, full) relatively more valuable than CCA deductions (deferred, declining).
- Does the lease include maintenance? Some dental equipment leases bundle service contracts, calibration, and software updates. If the alternative is purchasing the equipment and separately contracting for maintenance, factor the maintenance cost into your purchase-side calculation.
Pro Tip: Before signing any lease, ask the vendor for a total-cost-of-lease document that shows every payment, the buyout amount, and the implicit interest rate. Compare this to a bank loan quote for the same equipment. Some dental equipment leases embed effective interest rates above 12% — substantially higher than the 6% to 8% available through equipment-specific bank financing in 2026.
Canadian Tax Considerations for Professional Corporations
Most Ontario dental practice owners operate through a professional corporation (PC). This adds a layer of planning to the lease-vs-purchase decision:
- Small business deduction: Canadian-controlled private corporations (CCPCs) qualify for the small business deduction on the first $500,000 of active business income, taxing it at a combined federal-provincial rate of approximately 12.2% in Ontario. Equipment deductions that reduce taxable income below this threshold have less tax impact per dollar than deductions applied against income taxed at the general corporate rate (approximately 26.5%).
- Salary vs dividend extraction: How the owner extracts income from the corporation affects the optimal timing of equipment deductions. Practices that pay primarily salary may prefer consistent lease deductions; practices that retain earnings and pay dividends may prefer the CCA approach to manage retained earnings strategically.
- Year-end timing: A purchase made late in the fiscal year still qualifies for CCA in that year (subject to the half-year rule). A lease started late in the year only provides deductions for the months of payments made. For December year-end corporations, a late-year purchase may provide a proportionally larger first-year deduction.
The Bottom Line
There is no universal right answer to the lease-versus-purchase question. The decision depends on your practice's specific circumstances: cash position, growth stage, tax situation, and equipment type. What matters is that you make the decision deliberately rather than defaulting to whatever the equipment vendor offers.
Every dental practice should run the numbers with their accountant before committing to either path. The vendor's financing offer is a starting point, not the answer — compare it against bank financing, evaluate the total cost over the equipment's life, and factor in your corporate tax rate and extraction strategy.

Frequently Asked Questions
Q: What CCA class does dental equipment fall into in Canada?
Most dental equipment — chairs, handpieces, sterilizers, imaging units, and operatory furniture — falls into CCA Class 8, which has a 20% declining balance rate. Computer hardware may qualify for Class 50 (55% rate), and certain manufacturing or processing equipment may fall into different classes. Your accountant should confirm the classification for each significant acquisition.
Q: Is it better to lease or buy a dental chair in 2026?
For long-life equipment like dental chairs (15 to 25 year useful life with minimal obsolescence risk), purchasing is typically more cost-effective over the equipment's life. The total cost of ownership is lower without embedded lease interest, and the CCA deduction still provides tax benefits. Leasing is generally better suited to technology-driven equipment with shorter innovation cycles.
Q: Can I deduct lease payments as a business expense in Canada?
Yes. Lease payments for business-use equipment are generally deductible as operating expenses in the period they are paid. The lessor (the company that owns the equipment) claims CCA rather than you. HST paid on lease payments is recoverable as an Input Tax Credit if your dental practice is registered for HST. Consult your accountant for practice-specific advice, particularly regarding $1 buyout leases that the CRA may reclassify.
