Year-End Tax Planning for Your Professional Corporation: A Smart Guide for Canadian Professionals

As a doctor, dentist, lawyer, or other regulated professional, your professional corporation (PC) is more than just a business structure—it’s a powerful financial tool. But to make the most of it, proactive year-end tax planning is essential. With the right moves, you can potentially save a substantial amount of money. This guide will walk you through the key strategies to review with your tax advisor before your fiscal year wraps up.

Unlocking the Tax Power of Your Professional Corporation

The standout benefit of using a PC is often the small business deduction (SBD). As a Canadian-controlled private corporation (CCPC), your PC may pay a much lower tax rate on the first $500,000 of its active business income (the federal limit for 2024).

What does this mean for you? Essentially, more money remains in your corporation after taxes. This gives you crucial flexibility—whether you want to reinvest in new equipment, build a savings reserve, or carefully time your personal income.

Of course, this advantage comes with a need for careful planning. You’ll need to navigate rules on investments held within the corporation, make wise choices about how you pay yourself, and be mindful of important deadlines.

Key Year-End Moves to Run By Your Advisor

1. Finding the Right Salary and Dividend Balance

Figuring out the most tax-effective way to pay yourself is a core part of PC management.

The Case for Salary:
 Taking a salary creates a business expense for your PC, lowering its taxable income. It also builds your RRSP contribution room for the future and counts toward your Canada Pension Plan (CPP) benefits. A standard strategy is to pay yourself enough salary to max out your RRSP for the year.

The Case for Dividends:
 Taking a salary creates a business expense for your PC, lowering its taxable income. It also builds your RRSP contribution room and counts toward Canada Pension Plan (CPP) benefits. A standard strategy is to pay yourself a salary high enough to maximize your RRSP contribution room for the year.

A Word of Caution:
 Setting your salary unusually low might raise red flags with the CRA. And if you’re thinking about distributing dividends to family members, the Tax on Split Income (TOSI) rules may apply. The good news is that many professionals qualify for TOSI exemptions — but your accountant should confirm before year-end.

2. Protecting Your Small Business Deduction

Your access to the prized small-business tax rate isn’t guaranteed. It can be reduced if your corporation earns too much income from passive investments—such as interest from stocks, bonds, or GICs held by the company or even rental income.

Here’s how the clawback works: if your PC’s passive investment income exceeds $50,000 in a year, your SBD limit for the next tax year starts to shrink. If that passive income hits $150,000, you could lose the SBD entirely (CRA Small Business Deduction Rules). This means your corporation will pay more tax, reducing after-tax cash available for reinvestment or compensation.

Your Year-End Play:
 Talk to your advisor about whether a year-end bonus or a higher salary could help. By pulling more money out as an active business expense, you lower the retained earnings available for passive investing, which can help safeguard your SBD.

3. Being Strategic with Bonuses

You can declare a bonus to yourself or key staff before the year-end and still deduct it as an expense for that tax year, even if the cash doesn’t actually leave the company’s account until up to 179 days later (CRA ITA Section 78(4)). This is a valuable tactic to lower your PC’s net income, helping you stay safely within the SBD limit or avoid other tax complications.

4. Keeping Shareholder Loans Square

If you’ve borrowed money from your corporation, it’s critical to do it by the book. That means having a formal loan agreement in place, charging at least the CRA’s prescribed interest rate, and sticking to a solid repayment schedule. If not, the entire loan amount could be treated as taxable personal income.

Picking the Right Firm

Not all accounting firms are equally equipped to handle professional corporations. Look for one that offers:

• Forward-Looking Advice: Your ideal firm contacts you before year-end to plan, not just after the fact to file returns.
• Modern Technology: They provide visual reports and digital models instead of static spreadsheets.
• Seamless Collaboration: They coordinate with your bookkeeper and integrate with your software.
• Straightforward Communication: They explain your options clearly and are transparent about their fees.

Your Pre-Year-End Checklist

Get a head start by gathering this information for your advisor:

• Your latest financial statements and a year-end forecast.
• A summary of the salary and dividends you’ve taken so far this year.
• How much investment income has your corporation earned?
• Your personal income and RRSP goals for the year.
• Details of any money you’ve borrowed from or loaned to the corporation.

The Bottom Line

Think of year-end tax planning not as an optional task, but as a critical part of owning a professional corporation. When you sit down early with an advisor who actually understands how professional corporations work, you give yourself the chance to cut unnecessary taxes, hold onto the deductions you’re entitled to, and keep more of what you earn.
