For most newcomers starting a business or freelancing in Canada, the first structure decision is: sole proprietorship or corporation? This guide explains both options honestly so you can make the right choice for your situation.
Sole Proprietorship: The Simple Start
A sole proprietorship is the simplest business structure in Canada. You and the business are legally the same entity — your business income is your personal income, and you are personally responsible for all business debts and obligations.
How to start: If you operate under your legal name, no registration is needed. If you use a trade name, register it provincially ($40–$60 depending on province). That is it.
Taxes: All business income is reported on your personal T1 tax return using Schedule T2125. Net income is taxed at your marginal personal rate. You also pay CPP contributions at 11.9% on net self-employment income up to the YMPE ($74,600 in 2026).
Best for: New freelancers, consultants, and service-based businesses just starting out, with income under approximately $80,000–$100,000 per year.
Corporation: The Separate Legal Entity
When you incorporate, you create a separate legal entity — the corporation — that is distinct from you as an individual. The corporation owns the business, signs contracts, and is liable for its debts. You own shares in the corporation.
How to start: File Articles of Incorporation with your provincial government ($275–$350) or federally ($200). Also requires a minute book, directors’ resolutions, and share issuance.
Taxes: The corporation pays corporate income tax on its profits. Canadian-Controlled Private Corporations (CCPCs) pay approximately 12.2% on the first $500,000 of active business income in Ontario (9% federal + 3.2% provincial, reducing to 11.2% after July 1, 2026). You then pay personal tax on salary or dividends you take from the company.
Side-by-Side Comparison
| Factor | Sole Proprietorship | Corporation |
|---|---|---|
| Setup cost | $0–$60 | $200–$350+ government fees |
| Annual admin cost | Minimal | $1,000–$3,000+ (accounting, filings) |
| Personal liability | Unlimited — personal assets at risk | Limited — corporation’s assets only |
| Tax on first $500K income | Marginal personal rate (20–53%) | ~12.2% corporate (ON), then personal on withdrawals |
| Income splitting | Not possible | Possible via dividends to spouse/family (with restrictions) |
| GST/HST | Same rules apply | Same rules apply |
| CRA compliance | T1 + T2125 annually | T1 personal + T2 corporate annually |
| Banking | Can use personal or business account | Must use corporate bank account |
The Tax Math: When Incorporation Saves Money
Incorporation saves tax only when you earn more than you need to live on. Here is why:
If your net business income is $60,000 and you need all of it to cover your living costs, incorporation does not help — you draw the $60,000 as salary or dividends, pay personal tax, and end up with similar after-tax income as a sole proprietor.
If your net business income is $150,000 and you only need $80,000 to live on, incorporation creates a real advantage: the corporation pays ~12% on the retained $70,000 (vs your marginal rate of ~43%), and you defer personal tax on those retained earnings until you withdraw them. The $70,000 grows inside the corporation at a much lower initial tax cost.
General rule of thumb: Incorporation becomes tax-advantageous when you consistently earn $80,000–$100,000+ in net business income and do not need to withdraw it all for personal use.
What Newcomers Should Know
As a newcomer, start as a sole proprietor unless one of these conditions applies:
- A client explicitly requires you to be incorporated to sign their contract
- You are entering a field with significant liability exposure (e.g., engineering, construction, healthcare-adjacent services)
- Your income is above $100,000 from day one (unusual, but possible for experienced technical contractors)
Incorporation adds accounting complexity, a second tax return (T2), and annual maintenance costs. For a newcomer still establishing themselves in the Canadian market, this overhead is rarely justified in the first 1–2 years.
Frequently Asked Questions
Can I convert from sole proprietorship to corporation later?
Yes. The transition is called “rolling over” your sole proprietorship into a corporation (using CRA’s Section 85 rollover to defer tax). Most accountants handle this routinely. You do not lose your business history — you simply transfer assets into the new corporation.
Do I need a Canadian address to incorporate?
Yes. Both federal and provincial corporations require a registered office address in Canada. This can be a business address, lawyer’s office, or registered agent address — not necessarily where you live or work.
What is the difference between a federal and provincial corporation?
A federal corporation (incorporated through Corporations Canada) has Canada-wide name protection and can operate in all provinces without incorporating separately in each one — though it must still register extra-provincially in provinces where it does business. A provincial corporation has name protection only in the home province and must register extra-provincially to operate in other provinces.
