Retiring Dentist in BC with a $2M Practice Sale: Share Deal vs Asset Deal in 2026

The Scenario: Dr. Karen Osei's $2M Vancouver Dental Practice

Dr. Karen Osei, 62, has run a general dentistry practice in Vancouver since 1998. The practice operates through a BC professional corporation she wholly owns. A younger dentist wants to buy the practice for $2,000,000. Karen's adjusted cost base on her shares is $100 — the nominal subscription price at incorporation 28 years ago.

The practice has three dental operatories, digital imaging equipment, a patient base of approximately 2,800 active patients, and a lease with 8 years remaining on a high-traffic Vancouver location. The buyer has financing in place and wants to close within 90 days.

The disagreement is structure. Karen wants a share sale to access the $1,250,000 LCGE. The buyer wants an asset deal for the stepped-up CCA base on equipment and the ability to deduct $1.4M of goodwill through Class 14.1. Both positions are economically rational — the question is who absorbs the tax cost of the other side's preference.

The Share Deal: LCGE Shelters $1.25M, the $750K Slice Gets Taxed

In a share sale, Karen sells her shares in the professional corporation directly to the buyer (or to the buyer's holding company). The corporation — with all its assets, liabilities, patient records, contracts, and lease — transfers intact. Karen's personal tax calculation runs entirely on her T1 return as a capital gain on the disposition of shares.

The math on Karen's $2M share sale, assuming her shares qualify as QSBC shares and she has never previously claimed the LCGE:

• Capital gain: $2,000,000 minus $100 ACB = $1,999,900 (round to $2,000,000)
• LCGE claimed: $1,250,000
• Remaining taxable gain: $750,000
• First $250,000 at 50% inclusion: $125,000 taxable income
• Remaining $500,000 at 66.67% inclusion: $333,350 taxable income
• Total taxable income from sale: ~$458,350

At BC's top combined marginal rate of 53.50%, the tax on the share sale lands in the range of $195,000 to $210,000 depending on Karen's other 2026 income. Net after-tax proceeds: approximately $1,790,000 to $1,805,000 before professional fees of roughly $80,000 to $100,000 on a dental practice transaction (legal, accounting, dental practice broker, regulatory transfer fees). Working number: approximately $1.7M deployable.

The Asset Deal: Recaptured CCA Hits at Full Income Rates

In an asset sale, Karen's corporation sells its individual assets — dental equipment, leasehold improvements, supplies, patient goodwill, and the lease assignment — to the buyer. The corporation receives $2,000,000 and Karen still owns the now-asset-stripped corporation. She then needs to extract the proceeds from the corporation, typically through dividends and a wind-up under Section 88(2) of the Income Tax Act.

The tax hits in two layers.

Layer 1: Corporate-level tax on the asset sale

The $2M purchase price gets allocated across asset categories in the asset purchase agreement. A typical dental practice allocation:

• Dental equipment and leasehold improvements: $400,000 — triggers CCA recapture on any amount above the existing undepreciated capital cost (UCC) in the relevant CCA classes. If equipment originally cost $600,000 and has been depreciated to $80,000 UCC, the recaptured amount is $320,000 — taxed as ordinary business income at the corporate level.
• Supplies, inventory, receivables: $200,000 — taxed as ordinary income to the extent it exceeds the corporation's cost base in these items.
• Goodwill: $1,400,000 — allocated to Class 14.1. The gain above the corporation's existing Class 14.1 balance generates a mix of business income (recaptured CCA on prior cumulative eligible capital deductions) and capital gain on the remainder.

The total corporate-level tax on the asset sale depends heavily on the allocation, but typically runs $120,000 to $160,000 on a $2M dental practice — a combination of corporate tax on recaptured CCA at the general rate of approximately 27% in BC and corporate capital gains tax at approximately 50% on the goodwill gain (federal refundable tax plus BC provincial rate).

Layer 2: Personal tax on extracting the proceeds

After corporate-level tax, approximately $1,840,000 to $1,880,000 sits inside the corporation. Karen needs to get it out. The standard extraction mechanism is dividends — either eligible dividends (if paid from income taxed at the general corporate rate) or non-eligible dividends (if paid from income taxed at the small business rate). At BC's top combined rates, eligible dividends are taxed at approximately 36.54% personally, and non-eligible dividends at approximately 48.89%.

On a wind-up under Section 88(2), amounts distributed above the shares' paid-up capital are treated as deemed dividends. The combined corporate-then-personal tax on the full $2M asset sale typically lands between $380,000 and $420,000 — roughly double the share-sale outcome.

The Buyer's Perspective: Why the CCA Step-Up Is Worth Fighting For

From the buying dentist's perspective, an asset deal on a $2M practice generates significant future tax deductions that a share deal does not.

On $400,000 allocated to dental equipment (Class 8, 20% declining balance), the buyer claims $80,000 of CCA in year one — a deduction worth approximately $21,600 at BC's combined corporate rate, reducing the effective cost of the equipment. On $1,400,000 allocated to goodwill (Class 14.1, 5% declining balance), the buyer claims $70,000 of CCA per year — worth approximately $18,900 annually in tax savings. Over 10 years, the CCA deductions on goodwill alone are worth approximately $150,000 to $170,000 in present-value tax savings to the buyer.

In a share deal, the buyer inherits the corporation's existing UCC balances — often near zero on equipment after 28 years of depreciation. The buyer gets no fresh CCA deductions on equipment and no goodwill deduction at all. That is why buyers push hard for asset deals: the CCA step-up is worth $200,000 or more to them over the first decade of ownership.

Bridging the Gap: The Price Adjustment Negotiation

The share-vs-asset negotiation in dental practice sales is not a zero-sum game. The standard approach is to meet in the middle through a price adjustment: the buyer pays a share-deal price that is lower than the asset-deal price by an amount that reflects the buyer's lost CCA benefits, while the seller accepts the discount because the after-tax proceeds on a share deal (even at a lower headline price) exceed what the seller would net on an asset deal at a higher headline price.

On Karen's $2M practice: if the buyer values the CCA step-up at approximately $175,000 to $200,000, the negotiated share-deal price might land at $1,850,000 to $1,900,000 rather than $2,000,000. Karen's after-tax proceeds on a $1,900,000 share sale (with LCGE) are approximately $1,620,000 — still significantly higher than the approximately $1,580,000 to $1,620,000 she would net on a $2,000,000 asset sale after the two-layer tax hit. The buyer saves their CCA benefit into the discount. Both sides are better off than forcing the other into their non-preferred structure.

The Capital Gains Reserve: Spreading the $750K Gain Over 5 Years

If Karen's deal includes a vendor take-back note — common in dental practice sales where the buyer finances 15% to 25% of the purchase price through a promissory note rather than bank financing — the capital gains reserve under Section 40(1)(a)(iii) lets her spread the $750,000 post-LCGE taxable gain over up to 5 years.

At $150,000 of recognized gain per year, each year stays below the $250,000 threshold where the inclusion rate rises from 50% to 66.67%. The reserve keeps every dollar at the 50% inclusion rate — $75,000 of taxable income per year — rather than pushing $500,000 of the gain into the higher 66.67% tier in a single year.

The reserve saves approximately $30,000 to $40,000 compared to recognizing the full gain in one year. The trade-off is that Karen is effectively lending money to the buyer for several years, carrying credit risk if the buyer's practice declines. Most dental practice vendor take-back notes include a personal guarantee and a security interest in the practice assets to mitigate this risk.

LCGE Multiplication: Could Karen's Family Members Each Claim $1.25M?

The LCGE is a per-person exemption. If Karen's spouse or adult children held shares in the dental corporation (directly or through a family trust) and each individual's shares independently satisfied the QSBC tests, each could claim up to $1,250,000 of LCGE on their share of the gain. On a $2M sale, two LCGE claims would shelter the entire gain — reducing the tax from approximately $200,000 to near zero.

The practical barriers are significant. The Tax on Split Income (TOSI) rules under Section 120.4 apply the top marginal rate to income from shares held by family members who are not actively involved in the business. For dental corporations specifically, most provinces restrict share ownership of professional corporations to licensed dentists — meaning Karen's spouse and children cannot hold shares directly unless they are also registered dentists. Some structures use family trusts, but the TOSI rules and the QSBC 24-month holding-period tests make this planning extremely sensitive to timing and structure.

The estate freeze version of this strategy — freezing Karen's shares at a fixed preferred-share value and issuing growth shares to a family trust years before the sale — would have been worth significant tax savings if implemented 5 to 10 years ago. With a sale imminent, the window for LCGE multiplication has closed.

Post-Sale: Deploying $1.7M of After-Tax Proceeds

Assuming the share deal closes and Karen nets approximately $1.7M after tax and fees, the deployment sequence follows a priority ladder.

1. Max registered accounts ($110,000 to $150,000)

• TFSA: $109,000 cumulative room if Karen has never contributed (since 2009), plus $7,000 for 2026 = up to $116,000. All growth is tax-free.
• RRSP: $33,810 annual maximum for 2026, but Karen's actual room depends on earned-income history. A dentist who paid herself through dividends rather than salary may have little RRSP room. Salary and bonus declarations in the final years of practice can create RRSP room for post-sale contributions.

2. Eliminate non-deductible debt

Mortgage on personal residence, vehicle loans, credit lines. A 4.5% mortgage costs Karen 4.5% guaranteed after-tax — no equity portfolio reliably beats that on a risk-adjusted basis after dividend and capital gains tax.

3. Build the income bridge to CPP and OAS

At 62, Karen is 3 years from the earliest OAS eligibility at 65 and 8 years from the optimal CPP claim at 70 (the 0.7% per month enhancement to age 70 produces a 42% larger lifetime pension). The portfolio needs to replace her practice income during the bridge years without triggering OAS clawback — the recovery tax kicks in at $95,323 of net income and claws back 15 cents per dollar above that threshold. Drawing $90,000 per year from a mix of TFSA withdrawals (tax-free, no clawback impact) and capital-gains-oriented non-registered investments keeps Karen below the clawback threshold while maintaining her lifestyle.

4. Tax provision for the sale year and beyond

If Karen is using the capital gains reserve, she owes tax on $150,000 of recognized gain each year for 5 years. Setting aside $35,000 to $40,000 per year for the annual tax installment prevents a surprise bill every April. If the full gain is recognized in 2026, the $200,000 tax bill is due April 30, 2027 — set it aside in a high-interest savings account or short-term GIC immediately after closing.

Five Errors That Cost Retiring Dentists $100K or More

1. Failing to purify the corporation before the 24-month window

The most expensive mistake. A dental corporation with $500,000 in passive investments fails the QSBC tests. The full $1.25M LCGE is denied. Additional tax: approximately $400,000 or more at BC's 53.50% top rate.

2. Accepting an asset deal without pricing in the LCGE loss

If the buyer insists on an asset deal, the seller's asking price should increase by at least $150,000 to $200,000 to compensate for the lost LCGE. A $2M asset deal nets roughly the same as a $1.8M share deal after tax — so the asset-deal price should be higher, not the same.

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

A 100% cash deal at closing forecloses the reserve. The $30,000 to $40,000 savings from spreading the gain over 5 years is left on the table. Most dental practice buyers are open to 15% to 25% vendor financing — it actually helps the buyer's cash flow.

4. Paying dividends instead of salary in the final years before sale

RRSP room is based on earned income (salary, not dividends). A dentist who paid herself $200,000 in dividends for 10 years has zero new RRSP room. Switching to $200,000 salary in the final 2 to 3 years before retirement creates $33,810 of annual RRSP room — worth approximately $18,000 per year in tax-deferred growth over a 20-year retirement.

5. Parking $1.7M in a savings account and doing nothing for 6 months

Post-sale inertia is real. A dentist who has run a practice for 28 years is not used to managing a portfolio. Six months of $1.7M sitting in a chequing account at 0.05% interest is approximately $4,000 of forgone return — and the opportunity cost compounds. The deployment plan should be in place before closing, not after.

The Bottom Line: Structure First, Then Negotiate Price

On Karen's $2M BC dental practice sale, the deal structure determines the tax outcome before a single dollar of the purchase price is negotiated:

• Share deal with LCGE + 5-year reserve: ~$165,000 to $175,000 in tax, ~$1.7M deployable
• Share deal with LCGE, no reserve: ~$195,000 to $210,000 in tax, ~$1.7M deployable
• Asset deal (two-layer tax): ~$380,000 to $420,000 in tax, ~$1.5M deployable
• Share deal with LCGE denied (failed purification): ~$530,000 to $570,000 in tax, ~$1.35M deployable

The gap between the best outcome (~$165,000) and the worst (~$570,000) is over $400,000 — more than 20% of the sale price. That gap is decided in the 24 months before closing, not at the closing table.

If you are a dentist within 5 years of selling your practice in BC and have not had a tax and deal-structure review specifically focused on QSBC eligibility, corporate purification, and share-vs-asset modeling, the cost of waiting is measured in the hundreds of thousands. Our business sale planning team works with professional-corporation owners across BC to structure pre-sale purification, model both deal structures for the specific buyer, and build a post-sale deployment plan before the letter of intent is signed.
