Normally, we tell dentists who are getting ready to sell their practice: don’t spend a lot of money on equipment upgrades right before the sale.
There are good reasons for that advice. You might spend $100,000 or $200,000 upgrading dental chairs, buying a new digital pan/ceph, adding an intraoral scanner, replacing X-ray sensors, upgrading computers or modernizing your sterilization centre. Those upgrades may make your office look great, but a buyer may not value them dollar-for-dollar. The buyer may even prefer to choose their own equipment after closing.
There is also a timing problem. While the value of newer equipment may be reflected in a practice appraisal, the financial benefits of that investment may take months—or even longer—to show up in your financial statements. Did the new technology make the practice more efficient? Did the investment actually increase EBITDA? If you’re selling shortly after buying the equipment, there may not be enough history to prove it.
And under the traditional tax rules, you generally couldn’t deduct the entire equipment purchase immediately. Instead, the cost would usually be written off over time through Capital Cost Allowance (CCA). So, historically, making a large equipment purchase immediately before selling often didn’t make much sense.
Then, on September 15, 2026, the federal government announced its proposed Productivity Mega Deduction. Among other things, the proposal would allow businesses—including dental practices—to IMMEDIATELY deduct 100% of the cost of most qualifying equipment acquired on or after September 15, 2026, once it becomes available for use. That could dramatically change the math for dentists considering a sale.
What’s Canada’s New Mega Deduction?
The proposed changes matter if you are preparing to sell your dental practice because the tax benefit of a major equipment purchase may arrive much sooner than it would under the traditional rules.
Dental chairs, imaging systems, intraoral scanners, CAD/CAM equipment, sterilization equipment and certain computer systems may qualify. Timing and eligibility rules still apply, and the proposal remains proposed legislation.
How the Tax Savings Could Affect a Pre-Sale Upgrade
Consider an Ontario dentist planning to sell their practice in 2027. The dentist’s corporation purchases $200,000 of qualifying equipment before the sale. Assuming the corporation has sufficient taxable income and the income is subject to Ontario’s 11.2% combined small-business corporate tax rate, the numbers could look something like this:
| Amount | |
|---|---|
| Equipment purchased | $200,000 |
| Immediate tax deduction | $200,000 |
| Potential corporate tax savings | $22,400 |
| Effective after-tax cost | $177,600 |
This is a simplified example. Actual tax savings will depend on the corporation’s income, taxation year, applicable tax rate and other circumstances.
For a seller, the key point isn’t simply the $22,400 tax saving—it is that the immediate deduction reduces the effective cost of an upgrade that may also improve the practice before it goes to market.
And if some of that income would otherwise be taxed at the higher general Ontario corporate tax rate, the value of the deduction could be substantially greater. Remember, though: this isn’t free equipment. Your corporation is still spending $200,000. The potential advantage is receiving the tax deduction immediately instead of spreading it over many years.
Why Your Sale Structure Still Matters
Most dentist sellers would prefer to sell the shares of their dentistry professional corporation rather than having the corporation sell its individual assets. One important reason is the potential availability of the Lifetime Capital Gains Exemption (LCGE).
The proposed Mega Deduction creates another interesting consideration when comparing transaction structures. If your corporation sells depreciable dental equipment as part of an asset sale, some of the CCA previously claimed may come back into income as CCA recapture.
In a share sale, however, the corporation itself continues to own the equipment. The shareholder changes, but the owner of the equipment does not. As a result, the share sale itself generally does not trigger CCA recapture on that equipment.
That means a dentist may be able to benefit from an immediate deduction on a qualifying equipment purchase before a sale without that deduction automatically being reversed simply because the shares are sold.
There is still a trade-off. The purchaser acquires the corporation with its existing tax attributes, including the reduced tax value of equipment that has already been written off. A sophisticated purchaser may take that into account when negotiating the deal.
Could an Upgrade Make Your Practice More Valuable to a Buyer?
Possibly—but don’t assume that spending $200,000 means your practice is suddenly worth $200,000 more.
Buyers consider more than historical billings. They look at the condition of the office, age of the equipment, future capital expenditures, profitability, efficiency and opportunities for growth. Imagine two otherwise similar dental practices generating $1.5 million annually. One has aging chairs, outdated X-ray equipment and a sterilization centre that will soon need replacing. The other has modern operatories, digital scanners and recently upgraded equipment. Which one would you rather buy?
The newer practice may be more attractive because the purchaser doesn’t have to immediately spend hundreds of thousands of dollars modernizing it. Better technology may also improve efficiency, allow additional procedures to be performed in-house and potentially improve profitability. If those improvements translate into sustainable EBITDA, they may ultimately support a higher practice valuation.
But the key is buying equipment that makes business sense, not buying equipment simply to generate a tax deduction.
Don’t Forget About the Capital Gains Exemption
There may be another planning benefit. To qualify for the LCGE, a dentistry professional corporation must satisfy several tests concerning the nature of its assets, including tests relating to assets used principally in an active business carried on primarily in Canada. A corporation holding too much excess cash or passive investments can create problems.
Purchasing equipment genuinely used in the dental practice may improve the corporation’s mix of active-business assets. But don’t assume that buying equipment immediately before selling will automatically fix an LCGE problem. There are additional requirements, including historical tests that look back over the preceding 24 months.
This is something that should be reviewed with your accountant and lawyer well before the sale.
Five Things Dentists Should Consider Before Buying
- Your sale timeline: If you’re selling in three months, talk to your advisors—and potentially your buyer—before making a major equipment purchase. If you’re selling in one to three years, there may be more time for the investment to generate measurable financial benefits.
- Your corporate profits: The immediate deduction is most valuable when your corporation has taxable income against which it can actually use the deduction.
- The equipment itself: Focus on technology that improves productivity, expands treatment capabilities, reduces future capital expenditures or makes the practice more attractive to purchasers.
- HST and financing: Dentists generally can’t recover HST paid on equipment used in providing HST-exempt dental services. Financing costs, interest rates and cash flow also need to be considered.
- Your sale structure: The tax consequences of an equipment purchase can differ significantly depending on whether the eventual transaction is structured as a share sale or an asset sale.
Bottom Line
Canada’s proposed Productivity Mega Deduction could change some of the traditional advice we give dentists about upgrading a dental practice shortly before a sale.
A well-timed investment could provide an immediate tax deduction while modernizing your office, reducing a buyer’s future capital requirements and potentially improving the attractiveness or profitability of the practice. But that does not mean every pre-sale purchase will increase value—or that the tax result will be the same in every transaction.
If you’re considering selling your dental practice within the next one to three years, evaluate major equipment purchases as part of your broader sale strategy, including your timeline, profitability, expected transaction structure and the improvements a buyer is actually likely to value.
The question isn’t simply, “Can I deduct this equipment?” The better question is: “Will this investment strengthen my practice and ultimately help me walk away with more money when I sell?”
