The honest answer: it comes out over years, not at once
Getting the money out of a medical corporation is a draw-down plan, not a withdrawal. Everything you retained during practice was taxed once at the corporate rate; the second, personal layer of tax is charged as money leaves, and the total bill depends almost entirely on how fast you force it out. Take two million dollars in one year and much of it is taxed at the top personal rate. Take it over fifteen years, sized to fill the low and middle brackets beside your other income, and the same capital comes out at a fraction of the cost. Pacing is the whole game.
Retirement gives you two structural choices and one long project. The choices: keep the corporation alive after you stop practising, converted into an ordinary investment company, or dissolve it and take the tax hit up front. The project: a year-by-year sequence that blends corporate dividends with your RRSP, CPP and OAS so each source is drawn when it is cheapest. This page walks the timeline in order, because the work starts several years before your last clinic day.
One framing note before the detail. The corporation that funded your working life changes jobs at retirement: it stops being a practice vehicle and becomes the household's private pension. Physicians rarely have an employer pension, so the MPC's portfolio, built under the rules covered at can a medical professional corporation own investments, is usually the largest retirement asset in the family. Treating it with pension-level seriousness is not overkill; it is the job.
Five years out: set the corporation up to be drained
The last working years are for positioning, because several of the best tools only work while employment income and practice profit still exist. Salary in the final years builds the last of your RRSP room and supports individual pension plan funding, and an IPP can often be topped up meaningfully at retirement; dividends build none of that. The blend for the closing stretch deserves a deliberate re-run, and the mechanics are set out at salary vs dividends for incorporated physicians.
Get the corporation's notional accounts counted while there is still time to act on them. The capital dividend account holds the untaxed half of the portfolio's realized gains and can pay you completely tax-free dividends with an election; the refundable dividend tax on hand balances are recovered only as taxable dividends are paid, which argues for starting dividends before retirement rather than after. A corporation heading into retirement with these balances unmeasured is leaving mispriced money on the table in both directions.
Clean up the operating side deliberately rather than letting it trail off. That means collecting the final OHIP and third-party billings, settling staff obligations, ending or assigning the clinic lease, clearing equipment loans and the practice line of credit before practice income stops, and repaying any shareholder loan balances so nothing ugly crystallizes in the final year. Lenders will not extend practice credit to a corporation with no practice, so any financing the wind-down needs must be arranged while you are still billing.
Family positioning also has a deadline of sorts. A spouse can hold non-voting MPC shares now, and once you are 65 the tax on split income rules generally permit dividends to a spouse, mirroring pension splitting. Getting the share structure right before you leave practice, while the professional-corporation rules still govern who may hold what, avoids a scramble later and sets up the two-bracket draw-down that makes retirement income cheap.
The wind-down year: what happens to the corporation itself
When you stop practising medicine, the corporation cannot stay a medicine professional corporation, but it does not have to die. The usual path is to let the CPSO certificate of authorization go, amend the articles to drop the professional name and restrictions, and carry on as an ordinary Ontario corporation whose only business is holding investments. The share rules that limited ownership to physicians and family fall away with the professional status, which opens ordinary planning tools that were closed during practice, subject to the normal tax rules on family income.
Dissolving instead is simpler and usually costlier. A wind-up distributes everything at once, and the distribution above the shares' paid-up capital is taxed as a deemed dividend in a single year, which lands a large surplus in the top brackets and forfeits the pacing that makes gradual draw-down cheap. Dissolution earns its keep when the remaining balance is small enough that annual accounting and filing costs outweigh the tax saved by stretching, commonly at the end of the draw-down years rather than the start.
| Decision point | Keep it as an investment company | Wind it up now |
|---|---|---|
| Tax in year one | Only on what you choose to draw | Deemed dividend on essentially the whole surplus |
| Control over your bracket | Full: dividends sized year by year | None: one year absorbs everything |
| Ongoing cost | Annual corporate filings and accounting continue | Costs end once dissolution completes |
| Refundable balances | Recovered gradually as dividends are paid | Recovered at once, but against top-rate personal tax |
| When it fits | Meaningful surplus, multi-year horizon | Small remaining balance, or an estate simplifying itself |
Whichever path you take, the corporate file has to stay clean through the transition: final practice HST position confirmed, payroll accounts closed, the minute book brought current, and resolutions behind every distribution. The conversion itself, articles, College paperwork and tax elections in the right order, is defined-scope work we run as a Strategic Project, because sequence errors here are annoying and occasionally expensive to reverse.
The draw-down decade: sequencing the accounts
The draw-down is a sequencing exercise: several income sources, each taxed differently, arranged so every year's income lands as low in the brackets as the household's needs allow. Corporate dividends are the flexible piece, because you decide their size and timing; RRIF minimums, CPP and OAS arrive on their own schedules once started. The plan sets an annual dividend that tops the household up to its spending need, uses the two spouses' brackets once spousal dividends are permitted, and leaves the rest compounding inside the corporation.
The corporate side pays you back for good behaviour. Each taxable dividend recovers refundable tax for the corporation at a set rate per dollar paid, which quietly lowers the true cost of retirement dividends below the headline rate. Capital dividends from the CDA arrive tax-free whenever the balance and an election support them, and they are the tool for larger one-off needs, a renovation, a family gift, without disturbing the bracket plan. A draw-down that ignores these accounts overpays every single year.
Government benefits interact with all of it, mostly through the gross-up. Taxable Canadian dividends are grossed up on your personal return before the offsetting credit, so each cash dollar of dividend inflates the net income that OAS clawback and other income-tested benefits are measured against. That mechanism, plus your other income, drives the choice of when to start CPP and OAS and how large the corporate dividend should be in the years around them. There is no universal right order; there is a right order for your numbers, found by modelling a few candidate sequences.
Expect the plan to be boring to live with, which is the point. One planning conversation a year sets the dividend, the RRIF draw and the instalments; payroll is gone, and the corporation files one return with a small set of slips. Most retired physicians need far less accounting than they did in practice, and the annual tax-planning cycle, run through our tax planning work, is usually the whole engagement.
Selling something, and dying with the corporation full
Most family physicians have little to sell, and the plan should be honest about it. A roster and goodwill rarely command what owners hope, though clinic owners with associates, equipment or a cosmetic or diagnostic revenue stream may have a genuinely saleable business. Where a sale happens inside the corporation as an asset sale, the proceeds add to the surplus, the untaxed half of any goodwill gain credits the capital dividend account, and the draw-down plan simply starts from a bigger number.
Dying with a corporation still full is the scenario the plan must price, because the default outcome is double tax: your shares are deemed sold at fair market value on death, and the corporation's assets are taxed again as they are distributed to the estate. Well-established post-mortem tools, the subsection 164(6) loss carry-back in the estate's first year and the pipeline structure, exist precisely to collapse that duplication, but they are deadline-driven and work best when the corporate records are current and the executor knows the plan exists.
Two practical safeguards are worth putting in place early. First, corporate-owned life insurance can fund the terminal tax bill, and proceeds credit the capital dividend account so they can reach the family tax-free. Second, the will, the shareholder structure and the draw-down plan need to agree with each other, naming who inherits shares and what the executor should do in the first year. We build that alignment through our estate planning work, with the post-mortem mechanics documented next to the corporate file rather than discovered after the fact.
What changes the plan, and who should run it
The right retirement design for an incorporated physician turns on a handful of facts, and naming them is the first meeting's agenda:
- The size of the corporate surplus, which sets how many years the draw-down needs and whether keeping the corporation is worth its running cost.
- Your age and your spouse's age, because spousal dividends after 65 and two sets of brackets change the arithmetic materially.
- The household's other income, RRSP and RRIF balances, CPP entitlements, a spouse's pension, which fixes how much room the low brackets really have.
- The corporation's CDA and refundable-tax balances, which decide how much can come out tax-free or subsidized.
- Whether anything in the practice is saleable, since proceeds change both the size and the shape of the plan.
- Your estate intentions, because a corporation meant to outlive you is planned differently from one meant to be empty by 85.
This is exactly the work a CPA for incorporated healthcare professionals in Ontario should be leading: one plan covering the corporate conversion, the notional accounts, the dividend pacing, the benefit timing and the estate mechanics, written down and revisited annually. Walla Assaf's background in banking and corporate finance shows up here in the modelling and in the lender conversations that occasionally accompany a wind-down. The design itself is a defined-scope Strategic Project with a written fee, the annual execution is light, and both start with a free 15-minute discovery call from our Mississauga office. If you are winding down within five years, the best time for that call is now, while every option is still open.
