Corporation vs Sole Proprietorship in Ontario: Complete 2026 Comparison Guide

# Corporation vs Sole Proprietorship in Ontario: Complete 2026 Comparison Guide

**By Bader A. Chowdry, CPA, CA, LPA | Insight Accounting CPA**

Choosing between operating as a sole proprietorship or incorporating is one of the most important decisions Ontario business owners make. This choice affects your taxes, liability protection, administrative burden, and long-term growth potential.

After helping hundreds of Mississauga, Toronto, and GTA entrepreneurs structure their businesses, I’ve created this definitive 2026 guide comparing corporations versus sole proprietorships in Ontario.

At Insight Accounting CPA Professional Corporation, we use data-driven analysis to help clients choose the right structure—and we’ve seen clients save $15,000-$50,000 annually by making an informed choice.

## Understanding the Two Structures

### What is a Sole Proprietorship?

A sole proprietorship is the simplest business structure where you and your business are legally the same entity.

**Key characteristics:**
– No formal registration required (except business name registration)
– You report business income on your personal tax return (T1)
– Unlimited personal liability
– You ARE the business legally

**Example:** Sarah runs a freelance graphic design business in Mississauga. She registers the name “Sarah’s Design Studio” with the province, gets an HST number, and starts invoicing clients. She files a single T1 tax return reporting both her personal and business income.

### What is a Corporation?

A corporation is a separate legal entity distinct from its owners (shareholders).

**Key characteristics:**
– Formal incorporation with the province or federally
– Corporation files its own tax return (T2)
– Limited liability protection for shareholders
– More complex administration and compliance

**Example:** Mike incorporates “TechBuild Solutions Inc.” in Ontario. The corporation is a legal person that owns assets, signs contracts, and pays taxes separately from Mike personally. Mike is the sole shareholder and draws a salary or dividends.

## Complete Comparison: Corporation vs Sole Proprietorship

### 1. Taxation

#### Sole Proprietorship Tax Treatment

– **Tax return:** Personal T1 only
– **Tax rate:** Your personal marginal tax rate (20.05% to 53.53% in Ontario)
– **Business income:** Flows to Line 13500 of T1
– **Tax filing deadline:** April 30 (June 15 if self-employed)
– **Deductions:** Business expenses reduce taxable income
– **RRSP contribution:** Based on business income

**2026 Ontario Personal Tax Rates:**

| Taxable Income | Federal Rate | Ontario Rate | Combined |
|—|—|—|—|
| $0 – $55,867 | 15.00% | 5.05% | 20.05% |
| $55,867 – $111,733 | 20.50% | 9.15% | 29.65% |
| $111,733 – $173,205 | 26.00% | 11.16% | 37.16% |
| $173,205 – $246,752 | 29.00% | 12.16% | 41.16% |
| $246,752+ | 33.00% | 13.16% | 46.16% |
| $300,000+ | 33.00% | 20.53% | 53.53% |

**Tax calculation example:**
– Business profit: $100,000
– Personal deductions: $5,000
– Taxable income: $95,000
– Tax owing: ~$20,500
– **Effective rate: ~21.5%**

#### Corporation Tax Treatment

– **Tax return:** Corporate T2 + personal T1 (for salary/dividends)
– **Corporate tax rate:** Small business rate on first $500,000
– **Personal tax:** On salary or dividends drawn
– **Tax filing deadline:** 6 months after fiscal year-end
– **Deductions:** Corporate expenses + income splitting opportunities

**2026 Ontario Corporate Tax Rates:**

| Income Type | Federal | Ontario | Combined |
|—|—|—|—|
| Active business (first $500K) | 9.0% | 3.2% | 12.2% |
| Active business (over $500K) | 15.0% | 11.5% | 26.5% |
| Investment income | 38.7% | 11.5% | 50.2% (refundable) |

**Tax calculation example (same $100,000 profit):**
– Corporate profit: $100,000
– Corporate tax at 12.2%: $12,200
– After-tax retained: $87,800

If you draw salary:
– Salary paid: $60,000
– Corporate profit after salary: $40,000
– Corporate tax on $40,000: $4,880
– Personal tax on $60,000 salary: ~$11,400
– **Total tax: $16,280**
– **Tax savings vs sole prop: ~$4,200**

See our detailed [Personal Tax Planning](/personal-tax-planning/) strategies.

#### Tax Deferral Advantage

One of the biggest corporation benefits: **tax deferral**.

**Scenario:** You earn $200,000 but only need $80,000 to live on.

**Sole proprietorship:**
– Tax on $200,000: ~$60,000
– After-tax cash available: $140,000
– Cash for reinvestment: $60,000

**Corporation:**
– Pay yourself $80,000 salary
– Personal tax: ~$16,000
– Corporate profit: $120,000
– Corporate tax: $14,640
– **After-tax cash in corporation: $105,360**
– **Extra $45,000 available for reinvestment**

This deferral compounds over years, building significant wealth inside the corporation.

### 2. Liability Protection

#### Sole Proprietorship Liability

**Personal liability:** UNLIMITED

– All business debts are your personal debts
– Lawsuits against the business can seize personal assets
– Your home, savings, and investments are at risk

**Example risk scenario:**
Toronto consultant’s client sues for $500,000 alleging negligence. As a sole proprietor, the consultant’s personal home and savings are exposed even though they have professional liability insurance (coverage limits may not be enough).

#### Corporation Liability

**Personal liability:** LIMITED (with exceptions)

– Corporation owns business assets and debts
– Shareholders’ personal assets generally protected
– Lawsuits target the corporation, not you personally

**Exceptions (piercing the corporate veil):**
– Personal guarantees on loans
– Fraud or illegal activity
– Mixing personal and corporate funds
– Undercapitalized corporation
– Director liability for certain debts (HST, payroll source deductions)

**Example protection:**
Ontario software company incorporated as “CodeWorks Inc.” faces lawsuit over software defect. The corporation has $200,000 in assets. Shareholders’ personal homes and RRSPs are protected (assuming proper corporate governance).

**Important:** Incorporation doesn’t eliminate the need for insurance. You still need professional liability, general liability, and other coverage.

### 4. Income Splitting Opportunities

#### Sole Proprietorship Income Splitting

**Very limited options:**
– Pay spouse/family reasonable salary for actual work performed
– Pension income splitting (after age 65)
– RRSP contributions for spouse

**Restrictions:**
– Cannot split business income directly with family
– Attribution rules prevent income shifting

#### Corporation Income Splitting

**Significant opportunities:**
– Issue shares to spouse, adult children, family trust
– Pay dividends to family shareholders
– Pay reasonable salaries to family members for work performed
– Income sprinkling rules apply but still offer planning

**Income sprinkling tax (TOSI) rules:**
Since 2018, dividends to family members may be subject to top marginal tax rate unless:
– Family member is 18+
– Works 20+ hours/week in the business, OR
– Owns 10%+ of shares and company earns < 90% from services **Strategic example:** GTA manufacturing company owned 50/50 by husband and wife: - Corporate profit: $300,000 - Each takes $80,000 salary - Remaining profit: $140,000 - Each receives $70,000 in dividends - **Result:** Income split, each taxed at lower brackets vs one person taking $300,000 **Tax savings:** ~$25,000-$35,000 annually compared to sole proprietor structure Learn more about income splitting in our [Fractional CFO Services](/fractional-cfo-services/). --- ### 5. Business Growth and Financing #### Sole Proprietorship Growth Limitations **Raising capital:** - Personal loans (tied to personal credit) - Personal guarantees required - No ability to sell shares - Difficult to bring on partners without restructuring **Borrowing capacity:** - Limited to personal credit rating - Home equity lines of credit - Personal credit cards - Banks less willing to lend large amounts **Growth example:** Sole proprietor needs $200,000 for expansion: - Options: Personal loan, HELOC, or personal investors - Risk: All debt is personal liability - Challenges: Hard to attract serious investors #### Corporation Growth Advantages **Raising capital:** - Sell shares to investors - Preferred share structures for investors - Venture capital and angel investor access - Corporate credit rating separate from personal **Borrowing capacity:** - Corporate loans (with or without personal guarantee) - Business credit cards - Equipment financing - Lines of credit based on corporate performance **Growth example:** Corporation needs $200,000 for expansion: - Options: Corporate loan, investor equity, convertible debt - Risk: Corporation liable (personal assets protected if no guarantee) - Advantages: Can attract investors with equity upside **Real-world case:** Mississauga tech startup incorporated, raised $500,000 seed round by issuing 20% equity to investors. This would be impossible as sole proprietor. Our [Industry-specific services](/industries/) help growing businesses in Construction, Healthcare, Technology, Real Estate, and Manufacturing navigate expansion. --- ### 6. Credibility and Professional Image #### Sole Proprietorship Perception **Market perception:** - Viewed as smaller, less established - Some corporate clients prefer dealing with incorporated vendors - Government contracts often require incorporation - Less impressive to banks and investors **Branding:** - "John Smith Consulting" sounds individual - May signal startup or side business #### Corporation Perception **Market perception:** - Seen as more professional and established - "XYZ Solutions Inc." sounds larger and more permanent - Easier to win larger corporate contracts - Better positioned for B2B sales **Branding:** - Company name separate from personal identity - Easier to sell business (selling shares vs assets) - Continuity beyond owner **Real example:** Contractor bidding on municipal project worth $500,000: - As sole proprietor: Often disqualified or viewed as too small - As corporation: Meets minimum requirements, taken seriously --- ### 7. Sale and Succession Planning #### Selling a Sole Proprietorship **Process:** - Sell business assets individually - Cannot "sell the business" as a going concern easily - Capital gains treatment on goodwill and some assets - Lifetime Capital Gains Exemption (LCGE) NOT available **Tax on sale:** - Capital gains: 50% inclusion rate - Full income inclusion on inventory, accounts receivable - Recapture of CCA claimed **Succession challenges:** - Business tied to your identity - Difficult to transition to family members - No ability to transfer shares **Example:** Sole proprietor retires, sells client list and equipment for $400,000: - No LCGE available - Capital gains on $400,000: $200,000 taxable - Tax bill: ~$92,000 - **Net proceeds: $308,000** #### Selling a Corporation **Process:** - Sell shares (clean, simple transaction) - Or sell assets within corporation - Lifetime Capital Gains Exemption available (up to $1.016M in 2026) - Estate freeze strategies possible **Tax on share sale (qualifying small business shares):** - First $1.016M: Tax-free (LCGE) - Amount over $1.016M: 50% inclusion rate **Succession advantages:** - Gradual transfer of shares to family - Estate freeze locks in current value, future growth to next generation - Income splitting through family trust - Business continues as legal entity **Example:** Corporation owner retires, sells shares for $1.5M: - LCGE shelters first $1.016M - Capital gain on remaining $484,000: $242,000 taxable - Tax bill: ~$112,000 - **Net proceeds: $1,388,000** - **Tax savings vs sole prop: $80,000** See our [Review & Audit Services](/review-audit-services/) for due diligence on business sales. --- ## When to Choose Sole Proprietorship ✅ **Choose sole proprietorship if:** 1. **Revenue under $50,000/year** - Administrative costs of corporation not justified 2. **Low liability risk** - Service business with minimal risk exposure 3. **Side business or testing idea** - Not ready for corporate commitment 4. **Simple operations** - One person, no employees, straightforward bookkeeping 5. **Short-term venture** - Plan to wind up business soon 6. **Personal brand-driven** - Consultant/freelancer where YOU are the product 7. **Low profit margins** - Can't justify $5K-$15K annual corporate costs **Ideal sole proprietorship profiles:** - Freelance writer earning $35,000/year - Part-time photographer with minimal equipment - eBay reseller side hustle - New consultant testing market demand - Seasonal businesses (landscaping, snow removal) --- ## When to Incorporate ✅ **Choose corporation if:** 1. **Revenue over $100,000/year** - Tax deferral benefits justify costs 2. **High liability risk** - Construction, manufacturing, professional services 3. **Multiple stakeholders** - Partners, investors, or family ownership 4. **Retaining profits** - Don't need all profit for living expenses 5. **Growth plans** - Raising capital, hiring employees, expanding 6. **Selling in 5-10 years** - LCGE creates huge tax savings 7. **Income splitting potential** - Spouse or adult children involved 8. **Professional credibility needed** - Large clients prefer incorporated vendors **Ideal corporation profiles:** - Tech startup seeking investment - Profitable service business ($200K+ revenue) - Manufacturing with employees and equipment - Medical/dental professional corporation - Real estate developer - Any business with $75K+ annual profit to retain --- ## The "Sweet Spot" Analysis: When Incorporation Makes Financial Sense Let's calculate the break-even point where incorporation tax savings exceed the extra administrative costs. ### Assumptions: - Sole proprietor: Personal tax rate 37.16% (middle bracket) - Corporation: 12.2% on retained earnings - Extra corporate costs: $8,000/year - Profit retained in business (not withdrawn) ### Break-Even Calculation: Tax rate difference: 37.16% - 12.2% = **24.96% savings on retained profit** Break-even profit retention: $8,000 ÷ 24.96% = **$32,051** **Conclusion:** If you're retaining more than ~$32,000/year in the business, incorporation likely saves money even after accounting for extra costs. ### Real-World Example: **Scenario:** $150,000 business profit, need $80,000 to live on **Sole proprietorship:** - Tax on $150,000: ~$44,000 - Take-home: $106,000 - Living expenses: $80,000 - Available for reinvestment: $26,000 **Corporation:** - Salary to owner: $80,000 - Personal tax: ~$16,000 - Take-home: $64,000 (covers living expenses) - Corporate profit after salary: $70,000 - Corporate tax (12.2%): $8,540 - Corporate admin costs: $8,000 - **Available for reinvestment: $53,460** - **Extra $27,460 building in corporation** **Winner:** Corporation (by significant margin) --- ## Hybrid Approach: Start as Sole Prop, Incorporate Later Many Ontario entrepreneurs follow this path: ### Phase 1: Sole Proprietorship (Year 1-2) - Test business idea with minimal overhead - Build client base and revenue - Simple bookkeeping and tax filing - Low commitment ### Phase 2: Incorporation (Year 2-3) - Incorporate when revenue hits $75K-$100K - Transfer business assets and goodwill to corporation - Set up proper corporate governance - Implement tax planning strategies ### Transfer Process: 1. Incorporate new company 2. Transfer assets at fair market value (can defer tax using Section 85 rollover) 3. Close sole proprietorship 4. Notify clients and suppliers of new structure **Cost to convert:** $2,000-$5,000 (legal + accounting) Our [Corporate Tax Planning](/corporate-tax-planning/) team specializes in smooth transitions from sole prop to corporation. --- ## Provincial vs Federal Incorporation ### Ontario (Provincial) Incorporation **Advantages:** - Lower cost: $300 vs $200+ federal - Operate only in Ontario - Simpler annual filings **Disadvantages:** - Must register extra-provincially to operate in other provinces ($300-$500 each) - Name protection only in Ontario **Best for:** Businesses operating only in Ontario with no expansion plans outside province ### Federal Incorporation **Advantages:** - Name protection across Canada - Automatic right to operate in all provinces - Better for national/international growth - Perceived as more credible **Disadvantages:** - Higher upfront cost - Must still register in provinces where you operate - More complex compliance **Best for:** Businesses with multi-province operations or national growth plans **Recommendation for most Mississauga/GTA businesses:** Ontario incorporation is sufficient unless you have specific plans to operate in multiple provinces. --- ## Common Mistakes to Avoid ### Mistake #1: Incorporating Too Early **Problem:** Paying $5K-$15K/year in corporate costs when earning $30K profit **Solution:** Wait until profit justifies administrative burden (typically $75K+) ### Mistake #2: Not Maintaining Corporate Formalities **Problem:** Mixing personal and business expenses, no minute book, no annual meetings **Result:** "Piercing the corporate veil" - lose liability protection **Solution:** Maintain separate bank accounts, hold annual meetings, keep minutes, proper documentation ### Mistake #3: Wrong Salary/Dividend Mix **Problem:** Taking 100% salary or 100% dividends without optimization **Result:** Paying excess CPP or missing RRSP contribution room **Solution:** Work with CPA to calculate optimal mix for your situation ### Mistake #4: Ignoring Income Sprinkling Rules **Problem:** Paying dividends to family members without meeting TOSI exemptions **Result:** Dividends taxed at 53.53% (top rate) **Solution:** Ensure family members work 20+ hours/week or structure shares to qualify for exemptions ### Mistake #5: No Shareholder Agreement **Problem:** Multiple shareholders without written agreement on buy-sell, death, disability **Result:** Disputes, forced wind-up, or unfair buyouts **Solution:** Create comprehensive shareholder agreement at incorporation Our [Industry-specific expertise](/industries/) helps avoid these mistakes across Construction, Healthcare, Technology, Real Estate, and Manufacturing sectors. --- ## Frequently Asked Questions ### Q1: Can I switch from sole proprietorship to corporation mid-year? **Yes.** You can incorporate at any time. The corporation's fiscal year-end can be set strategically for tax planning. Work with a CPA to optimize timing. ### Q2: Do I need a lawyer to incorporate? **Not legally required** but recommended for complex situations (multiple shareholders, investor terms). Simple incorporations can be done online for $300-$400. However, having a lawyer review shareholder agreements is wise. ### Q3: What's the difference between a corporation and an LLC in Ontario? **LLC (Limited Liability Company) doesn't exist in Canada.** The equivalent is either: - **Corporation:** Most similar to US LLC for liability protection - **Limited Partnership:** For specific investment structures Most Ontario businesses choose incorporation. ### Q4: Can a corporation have one shareholder? **Yes.** You can be the sole shareholder, director, and officer. This is extremely common for small businesses. ### Q5: How do I pay myself from my corporation? **Three main methods:** 1. **Salary:** Creates RRSP room, pays CPP, qualifies for EI (if elected) 2. **Dividends:** No CPP, lower tax rate (with dividend tax credit), no RRSP room 3. **Mix of both:** Often optimal - discuss with your CPA ### Q6: Does incorporation protect me from CRA tax debts? **No.** Directors are personally liable for: - Unremitted HST - Unremitted payroll source deductions (income tax, CPP, EI) - Some penalty assessments **But:** Corporation's own income tax debt stays with corporation. ### Q7: Can I deduct startup costs if I incorporate? **Yes,** but treatment varies: - Incorporation legal fees: Deductible over 5 years - Pre-incorporation business expenses: Can be claimed by corporation if transferred properly - Equipment purchased before incorporation: Can be transferred to corporation ### Q8: What happens to my sole proprietorship debts when I incorporate? **They remain your personal debts** unless: 1. You formally transfer contracts/liabilities to corporation (creditor approval needed) 2. Corporation assumes debts (must be documented) 3. Personal guarantees remain in place Most sole prop debts stay personal even after incorporating. ### Q9: Is my corporation name protected forever? **Provincial incorporation:** Protected in Ontario only, as long as corporation exists and filings are current **Federal incorporation:** Protected Canada-wide **Important:** Trademark registration provides stronger protection for branding. ### Q10: Can I have multiple businesses under one corporation? **Yes.** One corporation can operate multiple business lines or divisions. However, you may want separate corporations if: - Different liability profiles - Planning to sell one business separately - Different ownership structures desired --- ## Decision Framework: 5-Step Process ### Step 1: Calculate Your Expected Profit Forecast realistic profit for next 12-24 months. Be conservative. ### Step 2: Assess Liability Risk **High risk:** Construction, manufacturing, professional services, anything with potential lawsuits **Low risk:** Low-value consulting, digital products, freelance services ### Step 3: Evaluate Income Needs vs Retention **Need most/all profit:** Sole prop may be simpler **Can retain 30%+ of profit:** Corporation likely beneficial ### Step 4: Consider 5-Year Plan **Short-term venture:** Sole prop simpler **Long-term growth, potential sale:** Corporation better ### Step 5: Run the Numbers **Work with a CPA to calculate:** - Tax in each structure - Administrative costs - Break-even analysis - 3-year projection Book a consultation: **(905) 270-1873** --- ## Take Action: Next Steps ### If You're Starting a Business: ☐ **Estimate first-year revenue and profit** ☐ **Assess liability risks in your industry** ☐ **Calculate personal income needs** ☐ **Book consultation with CPA** for personalized analysis ☐ **Register business name** (sole prop) or **Incorporate** (corporation) ### If You're Considering Incorporation: ☐ **Review last 2 years of financial statements** ☐ **Calculate retained earnings** you could leave in corporation ☐ **Assess growth and succession plans** ☐ **Get professional advice** on optimal timing ☐ **Plan Section 85 rollover** to defer tax on asset transfer ### If You're Already Incorporated: ☐ **Review corporate structure** with CPA annually ☐ **Optimize salary/dividend mix** each year ☐ **Maintain corporate minute book** and formalities ☐ **Consider income splitting** opportunities ☐ **Plan for succession or eventual sale** --- ## Let Insight Accounting CPA Guide Your Decision Choosing between sole proprietorship and corporation is a significant decision with long-term tax and legal implications.
