By Bader Chowdry, CPA, CA, LPA · Last updated May 3, 2026 · Reviewed May 3, 2026 · 5 min read
Quick answer: A Mississauga radiologist earning $480K through her MPC was on track to leave $19K of tax savings on the table due to suboptimal salary/dividend mix and missed RRSP timing. Q4 review and strategic adjustments: declared $35K bonus to top up CPP+RRSP room before December 31; held remaining cash inside corp at SBD rates; declared $40K of eligible dividends in January (next tax year) to defer personal tax; structured a corporate-level pension plan setup for 2025. Year-one personal tax saved: $19K. Year-two cash-flow optimization through dividend timing: $12K. Pension plan set-up positioned to add $40K/year corporate deduction starting 2025.
The challenge
A Mississauga radiologist earning $480K through her MPC was on track to leave $19K of tax savings on the table due to suboptimal salary/dividend mix and missed RRSP timing. Her previous accountant filed reactively, not proactively.

Frequently asked questions
1. How does this doctors 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. Doctors 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.
5. How is Insight Accounting CPA different from other GTA accounting firms on this work?
