The regulator decides the shape before tax planning starts. A professional corporation is not just a small company with a licence. It exists under the statute governing the profession, which sets who may hold shares and how it is named and permitted. Only then does the tax analysis — deferral, pay mix, retirement saving — matter. Most structuring mistakes reverse those steps. ## What is different about professional corporation accounting A professional corporation answers to a regulator as well as to the CRA, and the regulator usually decides who may hold shares. That single constraint shapes the remuneration options, the family-income planning that is available, and the value of the corporation on the way out. ### The regulator decides the share structure Each profession’s governing body sets its own share-ownership rules, varying by profession and province. Some allow family members non-voting shares; others restrict ownership to licensed members. The share structure drives every later option, so establish it first and change it carefully. Counsellors and clinical social workers face the same question; see [accounting for counselling practices in BC](https://www.everstonecpa.com/accountant-for-counsellors-bc). ### Income is high, stable and fully taxable in the year earned Unlike a product business, a practice has little inventory, few capital assets outside equipment and leaseholds, and income that arrives predictably. That makes the corporation primarily a timing tool: profit left inside is taxed at the small business rate now and the remainder when it is drawn out. Where a professional needs every dollar for personal spending, incorporation delivers little beyond cost, which is a legitimate conclusion, not a failure. ### Associated corporations share one small business deduction The reduced corporate rate covers a limited amount of active business income, shared among associated corporations. A professional with a practice corporation, a clinic corporation and a partnership interest can find it split in unintended ways. Association turns on control and share ownership, including family holdings, so it interacts with the regulator’s rules. ### Retained profit invested inside the company has a cost Investment income earned on funds left in the corporation is taxed at high rates, and above a threshold it also reduces access to the small business rate on the active practice income. For a practice that accumulates surplus year after year, that grind is the central planning question and the usual reason a holding company enters the conversation. ### Splitting income with family is narrow The tax on split income rules apply the top marginal rate to dividends paid to family members who are not sufficiently involved in the business, with exclusions that are hard for a professional practice to meet. Paying a spouse a reasonable salary for work actually performed remains available and defensible; paying dividends to a non-participating adult child generally is not. ### Practice-specific assets and events Buying into a practice, buying out a retiring partner, or acquiring goodwill are capital transactions with their own treatment, not deductible costs. Dental and medical practices carry equipment and leasehold improvements written off over defined periods, and lawyers and engineers carry unbilled work in progress. Each one changes what the year-end statements should show. ## The guides, tools and pages for this vertical Grouped by where a professional corporation is in its life: deciding and setting up, then running it, then the questions that arrive at the end of one. ### Deciding and setting up - [Accounting for incorporated professionals](https://www.everstonecpa.com/accountant-for-incorporated-professionals) — the service page: what an engagement covers for a professional corporation. - [Dental practice incorporation](https://www.everstonecpa.com/blog/dental-practice-incorporation-canada) — the profession-specific version, including equipment and associate arrangements. - [Model the incorporation decision](https://www.everstonecpa.com/incorporation-calculator) — models the difference between earning professionally and through a corporation.

It also fits professionals still deciding whether to incorporate, and those approaching a buy-in, buy-out or retirement. Consultants who are not licensed by a regulator have more structuring freedom and should start with the [agency and consulting hub](https://www.everstonecpa.com/agency-consulting-accounting). ## How this runs remotely EverStone CPA is a fully virtual, one-CPA firm. Professionals have the least flexible schedules, so meetings are by video outside clinic hours, records come electronically from the practice system and bookkeeper, and returns are filed directly with CRA. A dentist in Abbotsford and an engineer in Ottawa get the same process; only the regulator’s rules and provincial rate change. For the same questions answered against one set of facts rather than in the abstract, see [a worked Langley example](https://www.everstonecpa.com/blog/langley-incorporated-professionals-psb-home-office-pay). If the assessment puts you in the middle or high band, the next step is a written review of your actual arrangement.

Common questions ## Incorporated professionals — common questions **Can my spouse own shares in my professional corporation?** That is decided by the statute and regulator governing your profession in your province, not by tax law. Some professions permit family members to hold non-voting shares; others restrict ownership to licensed members. Even where shares are permitted, the tax on split income rules may still limit what can usefully be paid on them. [Ask about your case →](https://www.everstonecpa.com/quick-question) **Is incorporating worth it if I spend everything I earn?** Often not. A corporation mainly defers tax on income left inside it. If every dollar is drawn out for living costs, there is little deferral to gain and there is a corporate return, annual filings and regulator permits to pay for. The calculation changes as soon as income exceeds what the household spends. **What does it mean that my corporations are associated?** Associated corporations share one limit on income eligible for the reduced small business rate. Association turns on control and share ownership, including family holdings, so a practice corporation and a clinic or property corporation can be associated unintentionally. **Why does investing inside my corporation reduce my small business rate?** Once passive investment income inside the associated group exceeds a threshold, access to the reduced rate on active business income is progressively reduced. For a practice that has been accumulating surplus for years, that grind is usually the trigger for reviewing whether investments should be held somewhere else. **How is a practice buy-in treated?** Generally as a capital transaction, not a deductible expense: you acquire shares or an interest in assets and goodwill. Financing, and whether you buy personally or corporately, affect interest deductibility and the eventual sale. Structure it before signing. **Can I still contribute to an RRSP if I take dividends?** Dividends do not create RRSP contribution room; only salary does. That is one of the main non-tax consequences of a dividend-only compensation plan, alongside the absence of CPP contributions. Whether it matters depends on whether the corporation is expected to fund retirement instead. ## A CPA for professional corporations A buy-in on the table, a second corporation in the picture, or a compensation mix that has not been revisited in years — describe the structure and you will get a straight answer.
