Selling a dental practice in Canada frequently triggers a CRA audit, particularly when dentists claim the Lifetime Capital Gains Exemption (LCGE), which is up to $1,275,000 CAD as of 2026. The CRA heavily scrutinizes the allocation of the purchase price between equipment and goodwill. Securing a proper valuation and hiring a tax lawyer are essential to defend your tax-free gains.
Selling your dental practice is the culmination of decades of hard work. However, multi-million dollar transactions in cities like Toronto, Vancouver, and Calgary almost inevitably attract the attention of the Canada Revenue Agency (CRA). When an auditor comes knocking, their primary goal is to ensure you have not mischaracterized income to lower your tax bill.
The two biggest targets in these audits are the Purchase Price Allocation (PPA) and your eligibility for the Lifetime Capital Gains Exemption (LCGE). If the CRA disagrees with your filings, you could be reassessed for hundreds of thousands of dollars in back taxes.

Step-by-Step Process for Defending a Dental Practice Audit
Defending an audit of a corporate sale is highly technical. You and your legal team must prove that your practice met all federal requirements under the Income Tax Act at the exact time of the sale.
Step 1: Justifying the Purchase Price Allocation (PPA)
When a dental practice is sold, the total price must be divided between tangible assets (dental chairs, x-ray machines, leasehold improvements) and intangible assets (patient lists, brand reputation, or “goodwill”). Sellers generally prefer to allocate more value to goodwill because it is taxed favourably as a capital gain. 💸
The CRA auditor will challenge this. If they argue that too much was allocated to goodwill and not enough to equipment, you could face “recaptured depreciation,” which is fully taxable as regular business income. Your lawyer will defend your PPA by presenting the formal, independent valuation reports created during the sale process.
Step 2: Proving QSBC Share Status
To claim the lucrative LCGE, you must have sold shares of a Qualified Small Business Corporation (QSBC). The CRA enforces a strict “asset test.” They will demand proof that at least 90% of your dental professional corporation’s assets were actively used in your Canadian dental business at the time of the sale. 💼
If you held too much passive cash, real estate, or investment portfolios inside your dental corporation at the time of closing, the CRA may determine your shares were “offside” and deny your LCGE entirely. Your accountant and lawyer will need to reconstruct your balance sheet to prove compliance.
Step 3: Filing a Notice of Objection
If the CRA auditor refuses to accept your valuations and issues a massive reassessment, you must not simply accept it. Your tax law firm will file a formal Notice of Objection within 90 days of the assessment date. 📝
This moves your case out of the auditor’s hands and into the CRA Appeals Division. Here, your lawyer will submit binding case law from the Tax Court of Canada demonstrating why your goodwill valuation and share structure are legally sound.
How Much Does it Cost to Defend an Audit in Canada?
Defending the sale of a dental practice is a high-stakes scenario. Investing in top-tier legal and financial experts is critical when over a million dollars in tax exemptions are on the line. As of May 2026, here are the expected costs for your dental practice in CAD: 💰
| Service / Item | Estimated Cost (CAD) | Details |
|---|---|---|
| Initial Audit Management | $3,000 – $7,000 | Lawyer and accountant fees to deal directly with the CRA auditor. |
| Independent Practice Valuation | $5,000 – $15,000 | Hiring a Certified Business Valuator (CBV) to defend goodwill pricing. |
| Filing Notice of Objection | $5,000 – $12,000 | Drafting complex legal arguments for the CRA Appeals Division. |
| Tax Court Litigation | $20,000 – $50,000+ | Taking the dispute to the federal Tax Court of Canada if necessary. |
While these professional fees are substantial, they pale in comparison to losing the $1,275,000 LCGE and facing a sudden, massive tax bill plus interest penalties.
How Long Does the Process Take?
CRA audits of corporate sales are notoriously slow. The initial audit phase, where the auditor requests documents and asks questions, can easily take 6 to 18 months to complete. ⏱️
If the auditor rules against you and you file a Notice of Objection, expect another 1 to 2 years for the Appeals Division to render a decision. During this time, the CRA may require you to pay half of the disputed tax amount as a security deposit.
Frequently Asked Questions (FAQ)
What is recaptured depreciation?
Over the years, your dental corporation claimed Capital Cost Allowance (CCA) to deduct the depreciation of equipment. If you sell that equipment for more than its depreciated value on the books, the CRA “recaptures” those past deductions and taxes them as regular business income in the year of the sale.
What exactly is goodwill in a dental practice?
Goodwill represents the intangible value of your practice. It includes your established patient charts, the reputation of your clinic in the local community, phone numbers, and brand awareness. Because it is an intangible asset, its sale is treated as a capital gain.
Can the buyer and seller just agree on any price allocation?
No. While the buyer and seller negotiate the allocation in the Asset Purchase Agreement, the CRA is not bound by your contract. Under Section 68 of the Income Tax Act, the CRA has the power to reallocate the purchase price if they believe the amounts are unreasonable compared to fair market value.
Should my accountant or my lawyer handle the audit?
Your accountant should provide the financial records, but a tax lawyer should manage the communication with the CRA. A lawyer ensures that solicitor-client privilege protects your sensitive strategic discussions, whereas conversations with an accountant can be subpoenaed by the CRA.
