Incorporating your practice or business is one of the biggest financial decisions a professional makes — and one of the most misunderstood. Incorporation opens the door to real tax planning opportunities, but only if you actually use the structure deliberately. Too many incorporated professionals leave money in a corporation without a plan, pay themselves inefficiently, or miss strategies that could meaningfully reduce their lifetime tax bill.
This guide walks through the core tax planning decisions every incorporated professional should understand — and where to go deeper on each one.
Salary vs. Dividends: The First Decision You’ll Make Every Year
How you pay yourself from your corporation — salary, dividends, or a mix — affects your personal tax bill, your RRSP contribution room (only salary generates it), your CPP contributions, and how much cash flow you have for personal debt repayment or savings. There’s no single right answer; it depends on your personal cash needs, your corporation’s income, and your long-term goals. This decision should be revisited annually, not set once and forgotten.
Income Splitting With Family Members
If your spouse or adult children are legitimately involved in the business, paying them a reasonable salary for real work performed can shift income into lower tax brackets within the family unit. Canada’s Tax on Split Income (TOSI) rules significantly restrict dividend splitting with family members who aren’t actively involved, so this strategy requires careful structuring to stay compliant — it’s not a simple workaround.
Deciding What to Do With Retained Earnings
Once your personal spending needs are covered, surplus corporate income doesn’t have to sit as cash. Depending on your goals and timeline, retained earnings can be invested inside the corporation, used to fund an Individual Pension Plan, or held specifically to fund a future estate freeze or business sale. Where that money should actually go depends heavily on your age, your corporation’s structure, and how soon you’ll need it — this is worth its own dedicated conversation rather than a default “just leave it in the company” approach.
Estate Freezes and Succession Planning
As your corporation grows in value, an estate freeze — locking in the current value of your shares and allowing future growth to accrue to a trust or your children — can significantly reduce the tax bill your estate eventually faces, while also supporting succession planning if you plan to pass the business on. Timing matters here: freeze too early and you may need to unwind it; freeze too late and you’ve missed years of potential tax deferral. Understanding the right timing is one of the more technical parts of incorporated tax planning.
Section 85 Rollovers When Incorporating
If you’re transferring an existing unincorporated practice or business into a corporation, a Section 85 rollover allows you to do so on a tax-deferred basis rather than triggering an immediate capital gain. Getting this transfer structured correctly at the outset avoids an unnecessary tax bill and sets up cleaner books going forward — this is a detail worth getting right from day one, not something to fix after the fact.
Retirement Savings: RRSP, TFSA, or an Individual Pension Plan
Incorporation changes your retirement savings options. Beyond the standard RRSP and TFSA, incorporated professionals over roughly 45 with stable corporate income may find an Individual Pension Plan offers larger, tax-deductible contribution room than an RRSP alone. Comparing an IPP against continuing with an RRSP is a decision worth revisiting as your income and age change.
Winding Down or Selling the Corporation
Eventually, every incorporated professional faces the question of how to wind down or transition out of the corporation — whether through retirement, a practice sale, or a buy-sell arrangement with a partner. This transition is where many professionals make costly mistakes, often because it wasn’t planned for years in advance.
Why This Needs to Be a Coordinated Plan, Not a Checklist
Each of these decisions affects the others: how you pay yourself affects retained earnings, retained earnings affect your estate freeze timing, and your retirement savings strategy depends on how the corporation is structured heading into retirement. Tax planning for incorporated professionals works best as one coordinated plan reviewed regularly — not a series of one-off decisions made in isolation, often after the fact when a tax bill arrives.
