(Chartered Professional Accountant firm, Abbotsford, BC) service_area: British Columbia, Ontario and Manitoba --- [Home](https://www.everstonecpa.com/) [Blog](https://www.everstonecpa.com/blog) Incorporate vs Sole Proprietor: The Real Trade-Off Structure # Incorporate vs Sole Proprietor: *The Real Trade-Off* By EverStone CPA · August 2026 · 2 min read **Quick answer:** A sole proprietorship is you, doing business; a corporation is a separate legal person you own. That separation is the whole trade: it can shield personal assets and defer tax on profit left inside — in exchange for a corporate return, separate books, and real ongoing cost. The deciding variable is rarely revenue: it is [how much profit you can leave in the company](https://www.everstonecpa.com/blog/retained-earnings-canada). What this covers, at a glance. ## Liability and risk As a sole proprietor, business debts and claims are personal ones. A corporation is a separate legal person, which [can protect personal assets](https://www.everstonecpa.com/should-i-incorporate), though not absolutely: lenders often want personal guarantees, and professional liability follows the professional. The shield is real; it is just narrower than the brochure version. ## Tax and deferral A sole proprietor’s profit lands on the personal return in full, every year, at personal rates. A corporation’s active profit is taxed first at the small-business rate — [roughly 11% in BC](https://www.everstonecpa.com/incorporation-calculator), and personal tax applies only when money comes out. Draw everything you earn and the advantage mostly evaporates; leave profit inside and the deferral compounds. The [incorporation calculator](https://www.everstonecpa.com/incorporation-calculator) puts numbers on your own retained amount. **Deciding whether to incorporate?** We run your numbers both ways, then handle the set-up, the books from $300 a month and the first T2.

Those are real dollars — the [fee table](https://www.everstonecpa.com/pricing) shows them, and they are the reason incorporating too early is the most common structure mistake. ## How to decide: incorporate, or stay a sole proprietor Run the calculator on profit you would actually retain, not revenue. Watch the [personal services business trap](https://www.everstonecpa.com/blog/personal-services-business-psb-risk-canada) if most income comes from one client. And treat it as reversible judgement, not identity — the right structure at one stage is often wrong at another, which is what [an enquiry](https://www.everstonecpa.com/book-online?service=planning#enquiry-form) is for. [Email or book](https://www.everstonecpa.com/book-online?service=planning#enquiry-form)[Ask a question](https://www.everstonecpa.com/quick-question) General information, not tax advice. Every situation differs — confirm anything that affects a decision by [sending us an enquiry](https://www.everstonecpa.com/book-online?service=planning#enquiry-form). If the numbers point to incorporating, the next questions are structure and timing; [incorporation advice](https://www.everstonecpa.com/incorporation-advice) covers both. ## Common questions **At what income should I incorporate?** No single income figure is the trigger — the benefit grows once you are consistently leaving profit in the business beyond what you need to live on. Owners drawing everything out gain little from incorporating; owners retaining meaningfully into six figures usually have a real decision to make. [Ask about your case →](https://www.everstonecpa.com/quick-question) **Does incorporating protect me from all liability?** No — the corporation shields its own obligations, but lenders commonly require personal guarantees and professionals remain liable for their own work. The protection is real for trade creditors and many claims; it is not a force field. **Can I incorporate later, or switch back?** Both happen routinely. Starting as a sole proprietor and incorporating once profit justifies it is a normal path, and assets can generally be moved into a new corporation on a tax-deferred basis with the right election — planned, not improvised. ## Related reading [Should I incorporate?
