As an incorporated physician, you face a unique question that most Canadians never have to consider: where should your investment dollars go? Your Professional Corporation (PC) offers tax deferral on retained earnings, but registered accounts like RRSPs and TFSAs provide their own powerful benefits. The answer isn't either/or—it's about strategic sequencing.
The Physician's Financial Landscape
Unlike salaried professionals, incorporated physicians have a choice about how much income to take personally versus leaving in their corporation. This flexibility creates opportunities—and complexity.
The Case for Registered Accounts First
Despite the appeal of corporate tax deferral, registered accounts should generally be maximized before significant corporate investing. Here's why:
True Tax Shelter
RRSP: Tax-deferred growth. No tax until withdrawal, and contributions reduce current income.
TFSA: Completely tax-free growth. No tax on contributions, growth, or withdrawals—ever.
Corporate: Investment income is taxed annually, albeit at lower rates initially. Integration means eventual taxation upon extraction.
Creditor Protection
RRSPs receive strong creditor protection under federal legislation (except contributions in the 12 months before bankruptcy). TFSAs have some protection in some provinces.
Corporate assets are exposed to professional liability claims that pierce the corporate veil.
Income Splitting at Retirement
RRSP/RRIF income can be split 50/50 with a spouse after age 65, effectively cutting the tax rate on that income.
Corporate dividends must flow through the shareholder who owns the shares—less flexibility.
Simplicity
Registered accounts require minimal tracking. No T5013s, no RDTOH calculations, no CDA tracking.
Corporate investing adds complexity and accounting costs that reduce net returns.
How to Create RRSP Room as an Incorporated Physician
RRSP contribution room is based on earned income—which means salary, not dividends. To maximize RRSP room, you need to pay yourself a salary.
The Salary Strategy
To maximize RRSP room ($33,810 in 2026), you need earned income of $187,833. Verify current RRSP limits at Canada.ca.
But here's the key insight: the RRSP contribution refunds much of that tax. If you contribute the full $33,810 to your RRSP, you receive approximately $16,500-$18,000 back at top marginal rates. Effective personal cost is much lower than it appears.
The Corporate Investment Account: When It Makes Sense
Once registered accounts are maximized, corporate investing becomes the logical next step. But it comes with important considerations:
The Passive Income Problem
⚠️ The $50,000 Threshold
Since 2019, passive investment income over $50,000 annually reduces access to the small business deduction (SBD) for active business income. Every dollar of passive income above $50,000 reduces the SBD by $5, eliminating it entirely at $150,000 of passive income.
This can result in an additional 15-17% tax on your active medical income—a significant penalty.
Strategies to Manage Passive Income
📈 Capital Gains Focus
Only 50% of capital gains count as passive income. A $100,000 capital gain counts as $50,000 for the threshold—right at the limit.
💰 Dividend-Paying Equities
Canadian dividends integrate somewhat efficiently and may be preferable to interest income in the corporate context.
🏠 Real Estate Holdings
A separate holding company can own real estate, keeping rental income separate from your PC.
📋 Corporate Class Funds
These structures allow switching between mandates without triggering capital gains, deferring income recognition.
The Decision Framework
| Priority | Account | Rationale |
|---|---|---|
| 1 | TFSA | Tax-free forever; no income attribution; withdrawal flexibility |
| 2 | RRSP (via salary) | Tax deferral; income splitting at 65; creditor protection |
| 3 | FHSA (if applicable) | Combines RRSP + TFSA benefits for first-time buyers |
| 4 | Spousal RRSP | Maximize family registered room; income splitting |
| 5 | RESP (if children) | Government grants; income splitting to children |
| 6 | PC Corporate Account | Tax deferral on retained earnings; flexibility |
A Complete Example: Dr. Sarah Chen
Profile
- Family physician, incorporated
- Gross billings: $450,000
- Overhead: $100,000
- Net corporate income: $350,000
- Personal spending needs: $150,000/year
- Spouse: Part-time employee, lower income
- Two children under 10
Optimal Structure
Result: Dr. Chen maximizes all registered accounts, retains $100,000 annually for corporate investing, and keeps passive income well below the $50,000 threshold by focusing on capital gains strategies.
What About an IPP?
An Individual Pension Plan (IPP) is a defined benefit pension you create for yourself. It can allow larger tax-deductible contributions than an RRSP, especially as you age.
IPP vs. RRSP: When to Consider
Consider IPP If:
- Age 45+ with consistent high income
- Already maximizing RRSP contributions
- Significant RRSP room remains unused
- Want enhanced creditor protection
- Plan to work past 65
Stick With RRSP If:
- Under 45 years old
- Income varies significantly year to year
- May retire early
- Want flexibility and simplicity
- Plan to use RRSP meltdown strategy
Common Mistakes Physicians Make
Taking Only Dividends
Dividends don't create RRSP room. Physicians who take only dividends forgo thousands in registered account contributions annually.
Ignoring the Passive Income Rules
Building a large corporate portfolio without considering the $50,000 threshold can cost 15%+ on active business income.
Corporate GICs
Interest income is the worst type of passive income—fully taxable at corporate rates with no CDA credit.
Leaving TFSA Unfunded
TFSA room is limited and doesn't require salary—there's never a reason not to maximize it.
The Bottom Line
For most incorporated physicians, the optimal strategy is:
- Pay enough salary to maximize RRSP contribution room
- Maximize all registered accounts (TFSA, RRSP, Spousal RRSP, RESP, FHSA if applicable)
- Retain excess in the corporation for tax-efficient growth investments
- Monitor passive income to stay below the $50,000 threshold
- Consider an IPP once over 45 if registered accounts are maximized
