Sole Proprietorship vs. Incorporation in Canada

The decision between operating as a sole proprietor or incorporating affects your taxes, liability, and growth potential. Here's what BC business owners need to know.

One of the first big decisions a Canadian small business owner faces is choosing between operating as a sole proprietor or incorporating. Each structure changes how you pay tax, how much liability you carry, and how much admin you take on. Here’s what you need to know before deciding.

Liability — What’s at Stake

As a sole proprietor, you and your business are legally the same person. If your business is sued or can’t pay its debts, your personal assets — your home, car, savings — are on the line.

A corporation is a separate legal entity. Shareholders are generally not personally liable for corporate debts. We’ve seen BC business owners breathe easier knowing their family home is protected when they incorporate.

Tax Rates and Savings

  • Sole proprietors pay tax at their personal marginal rate — in BC, that can reach 53.5% on income over $253,000 (2025).
  • Corporations pay a lower small business rate on active income: 11% combined federal + BC on the first $500,000, then the general rate (approx. 27%).
  • Income left inside the corporation can grow tax-deferred, which helps with reinvestment and savings.
  • The lower corporate rate isn’t free money — when you eventually draw that income as dividends, it’s taxed again personally (the “integration” principle).

Administrative Burden

Sole proprietorship is straightforward: file a T2125 form with your personal tax return, keep receipts, track income and expenses. No separate T2 return, no corporate minutes, no annual filings.

Incorporation means annual T2 corporate tax returns, corporate minutes, annual BC registry filings, and often a separate bank account and accounting software. Expect $1,500–$3,000+ per year in additional accounting costs.

We’ve helped dozens of BC entrepreneurs set up their corporations and the consensus is: the extra paperwork is manageable, but you need good bookkeeping habits from day one.

CPP and RRSP Room

  • Sole proprietors pay both the employer and employee portions of CPP — 11.9% on net earnings between $3,500 and $69,700 (2025).
  • Incorporated owner-managers who take a salary create RRSP contribution room (18% of earned income, up to $32,490 for 2025). Dividends do not create RRSP room.
  • If RRSP room is important to you, incorporating and paying yourself a salary (at least up to the CPP max) keeps both CPP coverage and RRSP accumulation.

T4 vs. Dividends — Getting Paid

As a sole proprietor, you simply draw money from the business — it’s all personal income. No T4, no payroll, no source deductions.

As an incorporated owner-manager, you can pay yourself a salary (T4, payroll deductions, CPP) or dividends (no CPP, no T4, but no RRSP room either). Many owner-managers use a blended approach.

One client we worked with in Vancouver started as a sole prop earning $80K, incorporated at $120K, and saved roughly $8,000 in combined taxes in year one by splitting salary and dividends.
