Sole Proprietor vs. Corporation: Should You Incorporate?
The most common question we hear from Canadian business owners. Here’s the honest, plain-English comparison, and the point where incorporating actually starts to pay off. EverStone CPA walks new BC business owners through this decision every week.
Quick answer: A sole proprietorship is taxed at the owner’s personal rates on all profit, while a corporation is a separate taxpayer that can retain earnings at lower small business rates and defer personal tax. Incorporating usually pays off once profit exceeds what the owner needs to live on. EverStone models both scenarios.
There’s no universal answer — it depends on your profit, your risk, and how much you take out personally. Here’s how the two stack up.
| Factor | Sole Proprietor | Corporation |
|---|---|---|
| Tax on profit | Your personal marginal rate (up to ~53.5% in BC) | ~11% small-business rate in BC on the first $500k, then deferred |
| Liability | You’re personally on the hook | Limited — the company is separate from you |
| Setup & cost | Low — just register | Higher — incorporation + annual T2 & filings |
| Paperwork | One T1 with a T2125 | Separate T2, bookkeeping, payroll/dividends |
| Best when | Profit ≈ what you need to live on | Profit exceeds your personal spending |
The short version
If you’re spending everything the business earns, a sole proprietorship keeps life simple. The moment you’re consistently leaving profit in the business, a corporation lets you defer a big chunk of tax and adds liability protection — that’s usually the tipping point.

The forms and the dates
A sole proprietor reports on form T2125 with the T1 and pays personal rates on everything earned. A corporation files a T2 within six months of its year-end, pays the BC small business rate on the first $500,000 of active income, and pays the owner by salary (T4) or dividends (T5) — each with its own consequences for CPP, RRSP room and the personal return. Incorporating federally costs $200 online; provincially, BC Registries charges its own fee and the company keeps a BC annual report either way.
Who this is for in the Fraser Valley
The incorporation question comes up in the Fraser Valley at a recognisable moment: an Abbotsford or Chilliwack tradesperson whose income has crossed what they need to live on, a Langley or Surrey consultant being asked by a client to incorporate, a Mission farm operation bringing in the next generation. The answer depends on retained profit, liability exposure and what the next three years hold — and the corporation, once formed, has its own filings every year whether or not it earned anything.
