Choosing your business structure is one of the first — and most important — decisions you’ll make as a founder. The two most common options in Canada are sole proprietorship and incorporation. Each has real trade-offs.
Let’s break it down honestly.
The quick comparison
| Factor | Sole Proprietorship | Incorporation |
|---|---|---|
| Setup cost | $60–$200 | $300–$800 |
| Setup time | 1–3 days | 3–10 days |
| Liability | Unlimited personal | Limited to business assets |
| Tax rate | Personal rate (up to 53%) | Corporate rate (from 9%) |
| Ongoing compliance | Minimal | Annual returns, minute book |
| Raising investment | Difficult | Standard practice |
| Credibility | Moderate | High |
When sole proprietorship makes sense
A sole proprietorship is the simplest way to start a business. There’s no separate legal entity — you are the business.
This works well when:
- You’re freelancing or consulting solo
- Your revenue is under $30K–$50K/year
- You want minimal paperwork and compliance
- You’re testing a business idea before committing
When incorporation makes sense
Incorporation becomes the better choice when:
- Your annual revenue exceeds $50K–$75K (tax savings kick in)
- You want liability protection for personal assets
- You plan to hire employees or bring on partners
- You need to raise funding from investors
- You’re signing contracts with larger companies (many require it)
The tax difference
Here’s where it gets real. Let’s say you earn $100,000 in business income in Ontario:
As a sole proprietor:
- Taxed at your personal marginal rate
- Combined federal + provincial: ~$28,000 in tax
As a corporation:
- Corporate tax at small business rate: ~$12,500
- Remaining money stays in the corporation for reinvestment
- You only pay personal tax when you withdraw (salary or dividends)
That’s a $15,500 difference in year one alone.
What about the extra compliance?
Yes, corporations have more obligations:
- Annual returns to the federal or provincial government
- Corporate tax returns (T2) due 6 months after year-end
- Maintaining a minute book with resolutions, share records, and director info
- Separate bank account and bookkeeping
But with the right tools and support, this is manageable. At Preferway, we include ongoing compliance reminders and help with annual filings so nothing falls through the cracks.
Our recommendation
For most founders who are serious about building something, incorporation is worth the upfront investment. The liability protection alone justifies it. Add in tax savings, credibility, and the ability to raise funding, and the decision becomes clear.
If you’re just starting out and testing an idea, a sole proprietorship gets you moving fast. You can always incorporate later.
