Quick answer: A Toronto orthodontist selling her practice (associate buyer, $2. 12-month pre-sale restructuring: documented spouse's role as practice administrator (40+ hours/month over 5+ years — qualifies for Excluded Business). Capital gains tax avoided: $560K (full LCGE shelter on $2.0M of gain). Earnout structured to maximize CDA distributions ($165K tax-free). Net family proceeds: $2.4M instead of $2.0M.
The challenge
A Toronto orthodontist selling her practice (associate buyer, $2.8M) was facing $560K in capital gains tax. Practice was eligible for QSBC + LCGE but the share structure had spousal involvement that wasn't properly documented for TOSI Excluded Business test.
What we did
12-month pre-sale restructuring: documented spouse's role as practice administrator (40+ hours/month over 5+ years — qualifies for Excluded Business). Dual LCGE election: $1M each for orthodontist and spouse. Earnout component structured as capital dividend account distributions for 5-year tax-free extraction.
"Dental specialty practices often have $200K-$600K of LCGE you can capture if you start the planning 12+ months before sale. Last-minute calls cost you the entire opportunity." — Bader Chowdry, CPA, CA, LPA
The result
Capital gains tax avoided: $560K (full LCGE shelter on $2.0M of gain). Earnout structured to maximize CDA distributions ($165K tax-free). Net family proceeds: $2.4M instead of $2.0M.

Frequently asked questions
1. How does this dental specialist tax strategy apply to a smaller business?
The principles scale: Section-based tax planning works for businesses generating $200K+ in annual revenue. Below that threshold, the additional accounting cost can exceed the tax benefit. Dental Specialist businesses above $300K-$500K typically see net positive ROI from these strategies.
2. What is the realistic timeline to implement?
Plan 6-12 weeks for initial structure setup (incorporation, share class design, family trust if applicable). Add 24+ months waiting period if QSBC LCGE is involved. Annual maintenance is 2-4 hours of CPA review time.
3. How does CRA typically respond to this strategy?
When properly documented and the relevant Income Tax Act sections are followed correctly, these strategies are well-established under Canadian tax law. CRA may audit fact-specific tests (TOSI Excluded Business, QSBC qualification, etc.) but the structures themselves are not contested.
4. What are the typical professional fees for this type of engagement?
Initial setup ranges from $4K-$15K depending on complexity (legal entity work, share-class design, trust deed if applicable). Ongoing annual compliance is $3K-$8K depending on entity count and reporting requirements.
