How much tax on a $3M BC dental practice sale — share deal vs asset deal?

Quick Answer

On a share sale, the $1,250,000 Lifetime Capital Gains Exemption (LCGE) shelters the first $1.25M of gain. The remaining $1,750,000 produces approximately $580,000 to $600,000 of personal tax at BC's top combined rate of 53.50%. On an asset deal, the corporation pays corporate-level capital gains tax at 66.67% inclusion on the full $3M gain, then the dentist pays a second layer of personal tax extracting the after-tax proceeds as dividends — total combined tax of roughly $950,000 to $1,050,000. The gap between the two structures: approximately $400,000. That's the LCGE at work.

The Setup: Dr. Priya Sandhu's $3M Vancouver Dental Practice

Dr. Priya Sandhu, 56, has operated a four-operatory general dentistry practice in Vancouver for 22 years through a BC professional corporation she incorporated in 2004. The practice generates roughly $1.8M in annual revenue, employs two associate dentists, three hygienists, and four support staff, and has been appraised at $3,000,000. The buyer is a dental service organization (DSO) looking to roll up independent practices across the Lower Mainland.

Priya's adjusted cost base on the shares is the nominal $100 she subscribed at incorporation. The corporation holds approximately $200,000 of dental equipment (depreciated), a leasehold interest, patient charts and goodwill comprising the bulk of the $3M valuation, and $350,000 of excess cash and short-term investments accumulated over two decades of retained earnings.

ComponentValue
Practice valuation$3,000,000
Priya's ACB on shares$100
Capital gain on share sale~$3,000,000
2026 LCGE (QSBC shares)$1,250,000
Taxable gain after LCGE (share deal)$1,750,000

The DSO buyer wants an asset deal — they want the patient charts, the equipment, the lease assignment, and the goodwill, without inheriting the professional corporation's history. Priya wants a share deal — she wants the $1,250,000 LCGE. The negotiation over deal structure is a negotiation over who absorbs roughly $400,000 in tax.

The decision lever: On a $3M dental practice sale in BC, the share-deal-versus-asset-deal choice is worth approximately $400,000. That number is bigger than the value of the dental equipment, bigger than a year of associate-dentist salary, and bigger than most planning decisions the seller will ever make. It gets decided in the deal-structure negotiation, not at the tax-filing stage.

Path 1: The Share Deal — $3M Sale With the $1.25M LCGE

On a share sale, Priya personally sells her shares in the professional corporation to the buyer (or the buyer's acquisition corporation). The capital gain flows to Priya's personal T1 return, and the $1,250,000 LCGE for Qualified Small Business Corporation shares — claimed via Form T657 — shelters the first $1.25M of the gain entirely.

The remaining $1,750,000 of capital gain is taxed under the 2026 two-tier inclusion rules:

  • First $250,000 at 50% inclusion: $125,000 of taxable income
  • Remaining $1,500,000 at 66.67% inclusion: $1,000,050 of taxable income
  • Total taxable income from the sale: ~$1,125,000

At British Columbia's top combined federal-plus-provincial marginal rate of 53.50% (applicable above approximately $253,000 of taxable income in 2026), the bulk of this taxable income is taxed at or near the top rate. The personal tax bill from the share sale lands in the range of $580,000 to $600,000, depending on Priya's other 2026 income and any prior LCGE claims.

Net after-tax proceeds from the share deal: approximately $2,400,000, before legal, accounting, and broker fees of roughly $80,000 to $100,000 on a transaction of this size. Working number: $2.3M deployable.

Path 2: The Asset Deal — Corporate-Level Gain Plus Dividend Extraction

On an asset deal, Priya's professional corporation sells the individual assets — equipment, goodwill, patient charts, lease assignment — to the buyer. The corporation receives $3M. The gain is realized inside the corporation, not personally by Priya.

The corporate-level tax math differs from the personal math in two critical ways. First, corporations do not get the $250,000 threshold for the lower inclusion rate — all corporate capital gains are included at 66.67%. Second, the corporation cannot claim the LCGE — that exemption applies only to individual shareholders selling QSBC shares.

The asset-deal tax hits in two layers:

Layer 1: Corporate capital gains tax

The $3M sale price is allocated across assets. Equipment is sold at fair market value, triggering recapture of prior Capital Cost Allowance (CCA) claims (taxed as active business income) on the depreciated equipment. Goodwill — typically the largest component of a dental practice valuation — generates a capital gain. For simplicity, assume approximately $2.5M of the purchase price is goodwill and the remainder is equipment, lease value, and working capital.

On $2.5M of goodwill gain at 66.67% inclusion, the corporation's taxable income from the capital gain is approximately $1,667,000. The combined federal-plus-BC corporate tax on investment income (which includes capital gains realized by a CCPC) runs in the range of 50% of the taxable capital gain — approximately $835,000 of corporate tax on the goodwill gain alone, before accounting for the refundable portion.

Layer 2: Dividend extraction

After paying corporate tax, the corporation holds the after-tax proceeds. Priya must extract these funds personally — typically as dividends. A portion of the corporate tax paid on capital gains is refundable through the Refundable Dividend Tax On Hand (RDTOH) mechanism when non-eligible dividends are paid out to the shareholder. The integration system is designed so that the combined corporate-then-personal tax roughly equals the personal tax rate — but it is imperfect, and on large capital gains the friction adds up.

The combined corporate-plus-personal tax on the asset deal: approximately $950,000 to $1,050,000 on the same $3M transaction.

Side-by-Side: The $400K Gap

ItemShare dealAsset deal
Transaction price$3,000,000$3,000,000
LCGE claimed$1,250,000$0 (not available)
Taxable gain (personal or corporate)$1,750,000~$3,000,000
Total tax (all layers)~$590,000~$1,000,000
Net after-tax (before fees)~$2,410,000~$2,000,000
Gap~$400,000 more in the seller's pocket on a share deal

The $400,000 gap is almost entirely the LCGE. The exemption shelters $1,250,000 of gain that would otherwise be taxed at the seller's top marginal rate. At BC's 53.50% top combined rate with the 50%/66.67% tiered inclusion, the personal tax saved by the LCGE on a $3M sale is in the range of $380,000 to $420,000. That is the number Priya is fighting for in the deal-structure negotiation.

Does Priya's Dental Corporation Qualify for the LCGE?

The LCGE under Section 110.6 of the Income Tax Act applies only to Qualified Small Business Corporation (QSBC) shares. Three tests must all pass:

1. CCPC status at sale

The corporation must be a Canadian-Controlled Private Corporation at the time of disposition. Priya's wholly-owned BC professional corporation clears this. If the buyer is a foreign-controlled entity, the sequencing of the closing must ensure CCPC status is maintained through the moment Priya's shares transfer.

2. The 90% active-business test (at sale)

At the moment of sale, 90% or more of the corporation's assets by fair market value must be used in an active business carried on primarily in Canada. Dental practice revenue is clearly active business. The problem is Priya's $350,000 of excess cash and short-term investments. On a $3M enterprise value, the passive-asset ceiling is $300,000. Priya is $50,000 over the threshold — enough to disqualify the entire LCGE claim.

3. The 50% active-business test (24 months prior)

Throughout the 24 months before the sale, more than 50% of asset value must have been active-business assets. If Priya's passive assets exceeded 50% at any point in the prior two years, this test fails even if she purifies by closing. The 50% threshold is softer, but the 24-month look-back is unforgiving.

Priya's fix: She needs to purify — pay out approximately $50,000 to $100,000 of excess passive assets as a dividend to herself, or transfer passive investments to a separate holdco via Section 85 rollover. But here's the catch: the 24-month look-back means this purification must have been completed by mid-2024 if the sale closes in mid-2026. If the purification happened last month, the 90% at-sale test passes but the 24-month 50% test may still fail depending on the corporation's asset mix over the look-back period. For a detailed walkthrough of LCGE qualification and purification timing, see our guide to the LCGE in business sales.

The Capital Gains Reserve: Spreading $1.75M Over 5 Years

Section 40(1)(a)(iii) of the Income Tax Act allows a seller whose proceeds are paid in installments to claim a capital gains reserve, deferring recognition of the unpaid portion of the gain. The reserve formula caps at a minimum of 20% of the gain recognized per year — meaning the maximum deferral period is 5 years.

For Priya's $1,750,000 of post-LCGE taxable gain, structuring $750,000 of the $3M proceeds as a 4-year vendor take-back note lets her spread the taxable gain into roughly $350,000 per year across 5 years. The critical math: $350,000 of capital gain per year exceeds the $250,000 threshold where the 66.67% inclusion rate kicks in, so each year has approximately $100,000 of gain above the threshold.

Compare the two scenarios:

Recognition patternTotal taxable incomeApproximate tax
All $1.75M in year one$1,125,000~$590,000
$350K/year × 5 years (reserve)$1,125,000 total~$530,000
Savings from reserve~$50,000 to $70,000

The reserve savings are smaller than the LCGE benefit but still meaningful. The trade-off is credit risk — Priya is lending the buyer $750,000 secured by a promissory note, and if the buyer's practice struggles, collection may be difficult. Most DSO buyers will accept a vendor take-back structure because it spreads their cash outlay, but independent buyer-dentists may resist the complexity.

BC Professional Corporation Pitfalls for Dental Practice Sales

British Columbia's Health Professions Act imposes ownership restrictions on dental professional corporations that directly affect sale planning — and these restrictions are stricter than in some other provinces.

Voting-share restriction

In BC, only licensed dentists can hold voting shares in a dental professional corporation. Non-dentist family members, family trusts with non-dentist beneficiaries, and holdcos controlled by non-dentists cannot hold voting equity. This kills the most common LCGE multiplication strategy: having a spouse or adult children hold shares through a family trust, where each individual claims their own $1,250,000 LCGE on their share of the gain.

In provinces with more permissive professional corporation rules, a family trust holding growth shares could multiply the LCGE to shelter $2,500,000 or $3,750,000 of gain (two or three family members × $1.25M each). In BC, Priya is limited to her own single $1,250,000 LCGE unless other licensed dentists in her family hold qualifying shares — a rare scenario.

Buyer-pool constraint

The buyer of a BC dental professional corporation's shares must be a licensed dentist or a corporation wholly owned by licensed dentists. DSOs often structure acquisitions through a dentist-controlled acquisition vehicle to comply, but the regulatory layer adds complexity and narrows the buyer pool compared to non-regulated business sales.

College reporting requirements

The sale must be reported to the BC College of Oral Health Professionals. The corporation's name must comply with College naming requirements post-sale. These are administrative rather than tax issues, but they add closing costs and timeline risk if the College review flags compliance gaps.

The BC multiplier gap: A dentist in Alberta or Ontario selling a $3M practice through a family trust with two adult-child shareholders could potentially shelter up to $3,750,000 of gain across three LCGEs (owner + two family members), paying close to zero tax on a $3M sale. Priya, constrained by BC's professional corporation rules, can shelter only $1,250,000 — leaving $1,750,000 taxable. The provincial regulatory difference is worth approximately $400,000 to $500,000 of additional tax on a $3M sale.

Negotiating the Structure: Pricing the LCGE Into the Deal

When the buyer insists on an asset deal and the seller wants shares, the negotiation comes down to price adjustment. The standard framework: the seller calculates the after-tax proceeds on a share deal, then asks the buyer to pay enough on an asset deal to deliver the same after-tax result.

For Priya's $3M practice:

  • Share deal after-tax proceeds: ~$2,400,000 (before fees)
  • To match that on an asset deal, the buyer would need to pay approximately $3,350,000 to $3,400,000 — a 10% to 13% premium
  • The buyer's counter: they get a CCA step-up on the higher asset-deal price, which is worth roughly $200,000 to $300,000 in tax savings over the next 5 to 10 years through depreciation deductions

The typical landing zone on mid-market dental practice sales: the buyer pays a 5% to 10% premium on the asset-deal price, splitting the LCGE benefit roughly 50/50 between seller tax savings and buyer CCA benefit. On a $3M deal, that means an asset-deal price of $3,150,000 to $3,300,000 — still leaving Priya worse off than the pure share deal, but narrowing the gap to $100,000 to $200,000.

Post-Sale Deployment: $2.3M After Fees

Assuming the share deal closes and Priya nets approximately $2.3M after tax, legal, and advisory fees, the deployment plan follows four buckets:

Bucket 1: Max registered shelters ($140K to $150K)

  • TFSA: $7,000 annual limit in 2026, with cumulative room of up to $109,000 if Priya has never contributed (available since 2009 for residents 18+)
  • RRSP: $33,810 maximum in 2026, but actual room depends on Priya's prior years' earned income — a dentist paying herself through dividends rather than salary may have limited RRSP room

Bucket 2: Eliminate non-deductible debt

Mortgage on principal residence, line of credit, vehicle loan — any debt where the interest is not tax-deductible. In a high-rate environment, paying off a 4% to 5% mortgage is a guaranteed after-tax return that equity markets do not reliably beat.

Bucket 3: Income-producing portfolio ($1.8M to $2.0M)

The bulk of the proceeds get invested for long-term capital preservation and income generation. For a 56-year-old transitioning out of active practice, this portfolio replaces the dental practice income — typically through a globally diversified mix of low-cost ETFs scaled to Priya's risk tolerance and retirement timeline. For more on structuring post-sale investments, see our guide to business sale investment strategy.

Bucket 4: Tax provision

Set aside the first year's estimated tax payment before making optional deployment decisions. If Priya uses the capital gains reserve, the annual tax installment is smaller but extends over 5 years — she needs to adjust CRA installment payments accordingly.

Errors That Cost Dental Practice Sellers $200K–$500K

1. Failing to purify the corporation 24 months before sale

A dental corporation with $350,000 of passive investments on a $3M enterprise value is $50,000 over the 10% passive-asset threshold. If the purification happens within 24 months of closing, the 50% look-back test fails and the entire $1,250,000 LCGE is denied. Cost: approximately $400,000 in additional tax.

2. Accepting an asset deal without a price adjustment

The buyer asks for assets. The seller agrees at the same $3M price. The seller just gave away $400,000. Always price the LCGE benefit into the structure negotiation — a share deal at $3M is equivalent to an asset deal at roughly $3.35M for the seller.

3. Not negotiating a vendor take-back for the capital gains reserve

A 100% cash closing forecloses the reserve. On a $1,750,000 post-LCGE gain, the reserve saves $50,000 to $70,000 — money left on the table by not asking the buyer to defer 20% to 25% of the price as a promissory note.

4. Assuming BC allows LCGE multiplication through family trusts

Dentists who have heard about the family-trust LCGE multiplication strategy from their accountant or from other business owners may not realize that BC's professional corporation restrictions make this strategy unavailable for dental corporations. Implementing a non-compliant trust structure and having it unwound by the College — or denied by CRA — can cost the LCGE entirely.

5. Not coordinating LCGE with prior claims

If Priya claimed $200,000 of the LCGE on a prior investment or small business, only $1,050,000 of the 2026 $1,250,000 limit remains. CRA tracks lifetime LCGE usage via Form T657. Overclaiming triggers reassessment plus interest.

The Bottom Line: $590K of Tax or $1,000K — the Structure Decides

ScenarioTotal tax
Asset deal, no LCGE, corporate + dividend double tax~$1,000,000
Share deal, LCGE claimed, all gain in year one~$590,000
Share deal, LCGE + capital gains reserve over 5 years~$530,000

The spread between the worst structure ($1,000,000 on an asset deal) and the optimal structure ($530,000 on a share deal with reserve) is approximately $470,000 — more than 15% of the sale price. For Priya, the difference between retiring at 56 with $2.3M of deployable capital and retiring with $1.9M is entirely a function of deal structure and pre-sale planning, not practice valuation.

The planning window is the 24 months before closing. Purify the corporation's passive assets, negotiate for a share-deal structure (or price the LCGE into an asset-deal premium), include a vendor take-back note to access the capital gains reserve, and deploy the after-tax proceeds across maxed-out registered shelters and a diversified non-registered portfolio.

If you are a BC dentist within 5 years of selling an incorporated practice and have not had a deal-structure review focused on QSBC qualification, LCGE optimization, and BC professional-corporation constraints, the cost of that gap is $200,000 to $500,000.

Key Takeaways

  • 1A $3M BC dental practice share sale with the $1,250,000 LCGE produces approximately $580,000 to $600,000 in personal tax at BC's top combined rate of 53.50% — versus $950,000 to $1,050,000 in combined corporate-then-personal tax on an asset deal, a gap of roughly $400,000
  • 2The LCGE is available only on share sales of Qualified Small Business Corporation (QSBC) shares — the corporation must have 90% active-business assets at sale and 50%+ throughout the 24 months prior, meaning purification of passive investments must happen at least 24 months before a buyer letter of intent
  • 3Asset deals trigger corporate-level capital gains at 66.67% inclusion on the full gain (no $250K threshold for corporations), then a second layer of tax when the dentist extracts after-tax proceeds as dividends — the double-taxation layer is what makes asset deals so expensive for sellers
  • 4BC professional corporation rules restrict voting-share ownership to licensed dentists, limiting LCGE multiplication strategies through family trusts or spousal shareholdings that work in provinces with less restrictive professional corporation legislation
  • 5The capital gains reserve under Section 40(1)(a)(iii) can spread the $1,750,000 post-LCGE taxable gain over 5 years — keeping each year below the $250,000 threshold where the 66.67% inclusion rate kicks in — saving $50,000 to $70,000 if the deal includes a vendor take-back note
  • 6Buyers prefer asset deals (CCA step-up on equipment and goodwill, clean liability transfer) while sellers prefer share deals (LCGE access) — the price adjustment between the two structures is typically negotiated as a 10% to 15% premium on the asset-deal price to compensate the seller

Frequently Asked Questions

Q:How much tax does a BC dentist pay on a $3M share sale in 2026?

A:On a $3,000,000 share sale of a BC dental professional corporation with a nominal adjusted cost base, the $1,250,000 Lifetime Capital Gains Exemption (LCGE) for Qualified Small Business Corporation shares shelters the first $1.25M of the gain. The remaining $1,750,000 of capital gain is taxed in two tiers: the first $250,000 at 50% inclusion ($125,000 taxable), and the remaining $1,500,000 at 66.67% inclusion ($1,000,050 taxable). Total taxable income from the sale is approximately $1,125,000. At British Columbia's top combined federal-plus-provincial marginal rate of 53.50%, the personal tax bill on the share sale lands in the range of $580,000 to $600,000 depending on the seller's other 2026 income. Net after-tax proceeds before professional fees: approximately $2,400,000 to $2,420,000.

Q:What is the tax difference between a share deal and an asset deal on a $3M dental practice in BC?

A:The difference is substantial — roughly $400,000 to $500,000 in total tax. On a share deal, the dentist personally receives the $3M proceeds and claims the $1,250,000 LCGE, paying approximately $580,000 to $600,000 in personal tax on the remaining $1,750,000 gain. On an asset deal, the corporation sells the assets and pays corporate-level capital gains tax at 66.67% inclusion on the full gain (no LCGE at the corporate level), then the dentist pays a second layer of personal tax when extracting the after-tax proceeds as dividends. The asset deal produces roughly $950,000 to $1,050,000 in combined corporate and personal tax on the same $3M transaction. The LCGE — available only on a share sale — accounts for most of this gap.

Q:Does a BC dental professional corporation qualify for the LCGE?

A:Yes, provided the shares meet the Qualified Small Business Corporation (QSBC) tests under Section 110.6 of the Income Tax Act. The corporation must be a Canadian-Controlled Private Corporation (CCPC) at the time of sale. At the moment of disposition, 90% or more of the corporation's assets by fair market value must be used in an active business carried on primarily in Canada. Throughout the 24 months prior to the sale, more than 50% of asset value must have been active-business assets. Dental practices usually pass the active-business test — clinical revenue is clearly active business income. The risk is passive asset accumulation: if the dentist has built up excess cash, corporate investments, or a corporate-owned life insurance policy beyond roughly 10% of enterprise value, the shares fail the 90% test at sale. A $3M practice can hold no more than approximately $300,000 in passive assets and still qualify. Purification — paying out excess passive assets as dividends or transferring them to a separate holdco — must be completed at least 24 months before the sale to satisfy both the 90% at-sale test and the 50% look-back test.

Q:Why do buyers of dental practices often prefer an asset deal?

A:Buyers prefer asset deals for three reasons. First, an asset purchase lets the buyer allocate the purchase price to depreciable assets — dental equipment, leasehold improvements, and goodwill — creating new Capital Cost Allowance (CCA) deductions that reduce the buyer's taxable income for years after the acquisition. On a share purchase, the existing CCA pools carry over at their undepreciated capital cost, giving the buyer no step-up in depreciable asset basis. Second, an asset deal lets the buyer cherry-pick which assets and liabilities to acquire, leaving unknown or contingent liabilities (malpractice claims, employment disputes, lease obligations) with the seller's corporation. Third, if the practice has accumulated retained earnings, the buyer avoids acquiring a corporation sitting on a latent dividend-tax liability. The seller's incentive runs the opposite direction: a share deal provides LCGE access worth approximately $400,000 to $500,000 in tax savings on a $3M transaction. The negotiation usually lands on a price adjustment — the seller accepts a modestly lower share-deal price, or the buyer pays a premium on the asset deal to compensate the seller for the lost LCGE.

Q:How does the capital gains reserve work on a dental practice sale with a vendor take-back note?

A:Section 40(1)(a)(iii) of the Income Tax Act allows a seller who receives payment over multiple years to claim a capital gains reserve, deferring recognition of the portion of the gain attributable to unpaid proceeds. The reserve formula caps at a minimum of 20% of the gain recognized each year, so the maximum deferral period is 5 years. For a $3M dental practice share sale with $1,750,000 of taxable gain after the LCGE, structuring $600,000 to $750,000 of the proceeds as a 4-year vendor take-back note lets the seller spread approximately $350,000 of the gain into each of 5 years. Keeping each year's recognized gain at or below $250,000 ensures the entire gain is taxed at the 50% inclusion rate rather than the 66.67% rate that applies above $250,000 per year. The tax savings from the reserve on a $1,750,000 gain can reach $50,000 to $70,000 compared to recognizing the full amount in year one. The trade-off is credit risk: if the buyer's practice deteriorates, the vendor take-back note may not be fully collectible.

Q:What are the BC-specific professional corporation rules that affect a dental practice sale?

A:British Columbia's Health Professions Act and the College of Dental Surgeons of BC (now BC College of Oral Health Professionals) impose restrictions on dental professional corporation ownership that directly affect sale structuring. In BC, only licensed dentists can hold voting shares in a dental professional corporation — non-dentist family members, trusts, and holdcos controlled by non-dentists cannot hold voting equity. This restriction limits LCGE multiplication strategies that work in other provinces: the common approach of having a spouse or adult children hold shares through a family trust to access multiple $1,250,000 LCGEs may not be available if those family members are not licensed dentists. The buyer must also be a licensed dentist or a corporation wholly owned by licensed dentists, which narrows the buyer pool compared to non-regulated businesses. Additionally, the corporate name must comply with College naming requirements, and the sale must be reported to the College. These regulatory constraints make the share-versus-asset decision even more consequential for BC dentists, because the LCGE multiplication workaround that partially offsets an asset deal's tax cost in other provinces is typically unavailable.

Q:Can a dentist use an estate freeze before selling the practice to multiply the LCGE?

A:In theory, an estate freeze locks the current owner's shares at a fixed value (as preferred shares) while issuing new common growth shares to family members or a family trust — allowing multiple individuals to each claim their own $1,250,000 LCGE on the growth in value. In practice, BC's professional corporation rules severely limit this for dentists. Only licensed dentists can hold voting shares in a BC dental professional corporation, so issuing growth shares to a non-dentist spouse or adult children may not comply with the College of Dental Surgeons' ownership requirements. If the freeze was implemented years ago with compliant shareholders (such as an associate dentist who is also a family member), the strategy can work — each qualifying shareholder claims their own LCGE, potentially sheltering $2,500,000 or more of gain instead of just $1,250,000. The structure must satisfy the 24-month QSBC holding test for each shareholder, and the General Anti-Avoidance Rule (GAAR) can apply if the freeze was implemented on the eve of a sale rather than as genuine succession planning.

Q:What happens to the dental practice's retained earnings on a share sale versus an asset sale?

A:On a share sale, the buyer acquires the entire corporation — including any retained earnings sitting in the corporate bank account. The purchase price typically reflects the value of those retained earnings: if the practice has $500,000 of after-tax cash on the balance sheet, the $3M purchase price implicitly includes that cash. The seller does not need to extract the retained earnings before closing (which would trigger personal dividend tax). However, if those retained earnings represent passive investments rather than active-business working capital, they can disqualify the shares from QSBC status by pushing passive assets above the 10% threshold. The standard pre-sale move is to purify: pay out excess retained earnings as dividends to the seller personally (triggering dividend tax in the range of 30% to 39% depending on eligible versus non-eligible dividend status in BC) at least 24 months before the share sale, preserving QSBC eligibility. On an asset sale, retained earnings stay in the corporation after the transaction closes, and the seller must eventually extract all corporate funds as dividends — facing the second layer of personal tax regardless.

Question: How much tax does a BC dentist pay on a $3M share sale in 2026?

Answer: On a $3,000,000 share sale of a BC dental professional corporation with a nominal adjusted cost base, the $1,250,000 Lifetime Capital Gains Exemption (LCGE) for Qualified Small Business Corporation shares shelters the first $1.25M of the gain. The remaining $1,750,000 of capital gain is taxed in two tiers: the first $250,000 at 50% inclusion ($125,000 taxable), and the remaining $1,500,000 at 66.67% inclusion ($1,000,050 taxable). Total taxable income from the sale is approximately $1,125,000. At British Columbia's top combined federal-plus-provincial marginal rate of 53.50%, the personal tax bill on the share sale lands in the range of $580,000 to $600,000 depending on the seller's other 2026 income. Net after-tax proceeds before professional fees: approximately $2,400,000 to $2,420,000.

Question: What is the tax difference between a share deal and an asset deal on a $3M dental practice in BC?

Answer: The difference is substantial — roughly $400,000 to $500,000 in total tax. On a share deal, the dentist personally receives the $3M proceeds and claims the $1,250,000 LCGE, paying approximately $580,000 to $600,000 in personal tax on the remaining $1,750,000 gain. On an asset deal, the corporation sells the assets and pays corporate-level capital gains tax at 66.67% inclusion on the full gain (no LCGE at the corporate level), then the dentist pays a second layer of personal tax when extracting the after-tax proceeds as dividends. The asset deal produces roughly $950,000 to $1,050,000 in combined corporate and personal tax on the same $3M transaction. The LCGE — available only on a share sale — accounts for most of this gap.

Question: Does a BC dental professional corporation qualify for the LCGE?

Answer: Yes, provided the shares meet the Qualified Small Business Corporation (QSBC) tests under Section 110.6 of the Income Tax Act. The corporation must be a Canadian-Controlled Private Corporation (CCPC) at the time of sale. At the moment of disposition, 90% or more of the corporation's assets by fair market value must be used in an active business carried on primarily in Canada. Throughout the 24 months prior to the sale, more than 50% of asset value must have been active-business assets. Dental practices usually pass the active-business test — clinical revenue is clearly active business income. The risk is passive asset accumulation: if the dentist has built up excess cash, corporate investments, or a corporate-owned life insurance policy beyond roughly 10% of enterprise value, the shares fail the 90% test at sale. A $3M practice can hold no more than approximately $300,000 in passive assets and still qualify. Purification — paying out excess passive assets as dividends or transferring them to a separate holdco — must be completed at least 24 months before the sale to satisfy both the 90% at-sale test and the 50% look-back test.

Question: Why do buyers of dental practices often prefer an asset deal?

Answer: Buyers prefer asset deals for three reasons. First, an asset purchase lets the buyer allocate the purchase price to depreciable assets — dental equipment, leasehold improvements, and goodwill — creating new Capital Cost Allowance (CCA) deductions that reduce the buyer's taxable income for years after the acquisition. On a share purchase, the existing CCA pools carry over at their undepreciated capital cost, giving the buyer no step-up in depreciable asset basis. Second, an asset deal lets the buyer cherry-pick which assets and liabilities to acquire, leaving unknown or contingent liabilities (malpractice claims, employment disputes, lease obligations) with the seller's corporation. Third, if the practice has accumulated retained earnings, the buyer avoids acquiring a corporation sitting on a latent dividend-tax liability. The seller's incentive runs the opposite direction: a share deal provides LCGE access worth approximately $400,000 to $500,000 in tax savings on a $3M transaction. The negotiation usually lands on a price adjustment — the seller accepts a modestly lower share-deal price, or the buyer pays a premium on the asset deal to compensate the seller for the lost LCGE.

Question: How does the capital gains reserve work on a dental practice sale with a vendor take-back note?

Answer: Section 40(1)(a)(iii) of the Income Tax Act allows a seller who receives payment over multiple years to claim a capital gains reserve, deferring recognition of the portion of the gain attributable to unpaid proceeds. The reserve formula caps at a minimum of 20% of the gain recognized each year, so the maximum deferral period is 5 years. For a $3M dental practice share sale with $1,750,000 of taxable gain after the LCGE, structuring $600,000 to $750,000 of the proceeds as a 4-year vendor take-back note lets the seller spread approximately $350,000 of the gain into each of 5 years. Keeping each year's recognized gain at or below $250,000 ensures the entire gain is taxed at the 50% inclusion rate rather than the 66.67% rate that applies above $250,000 per year. The tax savings from the reserve on a $1,750,000 gain can reach $50,000 to $70,000 compared to recognizing the full amount in year one. The trade-off is credit risk: if the buyer's practice deteriorates, the vendor take-back note may not be fully collectible.

Question: What are the BC-specific professional corporation rules that affect a dental practice sale?

Answer: British Columbia's Health Professions Act and the College of Dental Surgeons of BC (now BC College of Oral Health Professionals) impose restrictions on dental professional corporation ownership that directly affect sale structuring. In BC, only licensed dentists can hold voting shares in a dental professional corporation — non-dentist family members, trusts, and holdcos controlled by non-dentists cannot hold voting equity. This restriction limits LCGE multiplication strategies that work in other provinces: the common approach of having a spouse or adult children hold shares through a family trust to access multiple $1,250,000 LCGEs may not be available if those family members are not licensed dentists. The buyer must also be a licensed dentist or a corporation wholly owned by licensed dentists, which narrows the buyer pool compared to non-regulated businesses. Additionally, the corporate name must comply with College naming requirements, and the sale must be reported to the College. These regulatory constraints make the share-versus-asset decision even more consequential for BC dentists, because the LCGE multiplication workaround that partially offsets an asset deal's tax cost in other provinces is typically unavailable.

Question: Can a dentist use an estate freeze before selling the practice to multiply the LCGE?

Answer: In theory, an estate freeze locks the current owner's shares at a fixed value (as preferred shares) while issuing new common growth shares to family members or a family trust — allowing multiple individuals to each claim their own $1,250,000 LCGE on the growth in value. In practice, BC's professional corporation rules severely limit this for dentists. Only licensed dentists can hold voting shares in a BC dental professional corporation, so issuing growth shares to a non-dentist spouse or adult children may not comply with the College of Dental Surgeons' ownership requirements. If the freeze was implemented years ago with compliant shareholders (such as an associate dentist who is also a family member), the strategy can work — each qualifying shareholder claims their own LCGE, potentially sheltering $2,500,000 or more of gain instead of just $1,250,000. The structure must satisfy the 24-month QSBC holding test for each shareholder, and the General Anti-Avoidance Rule (GAAR) can apply if the freeze was implemented on the eve of a sale rather than as genuine succession planning.

Question: What happens to the dental practice's retained earnings on a share sale versus an asset sale?

Answer: On a share sale, the buyer acquires the entire corporation — including any retained earnings sitting in the corporate bank account. The purchase price typically reflects the value of those retained earnings: if the practice has $500,000 of after-tax cash on the balance sheet, the $3M purchase price implicitly includes that cash. The seller does not need to extract the retained earnings before closing (which would trigger personal dividend tax). However, if those retained earnings represent passive investments rather than active-business working capital, they can disqualify the shares from QSBC status by pushing passive assets above the 10% threshold. The standard pre-sale move is to purify: pay out excess retained earnings as dividends to the seller personally (triggering dividend tax in the range of 30% to 39% depending on eligible versus non-eligible dividend status in BC) at least 24 months before the share sale, preserving QSBC eligibility. On an asset sale, retained earnings stay in the corporation after the transaction closes, and the seller must eventually extract all corporate funds as dividends — facing the second layer of personal tax regardless.
