When Should You Incorporate Your Business? A Complete Guide for Canadians
One of the most important financial decisions you’ll ever make as a Canadian business owner is whether—and when—to incorporate. Incorporation can save you tens of thousands of dollars in taxes, protect your personal assets, and set your business up for long-term success.
But it’s not the right move for everyone, and timing matters. At Booboo Accounting Services, we help Richmond Hill entrepreneurs make this decision with confidence every day. This guide breaks down exactly what incorporation is, who it’s for, and the key signs that it’s time to take the leap.
💡 Quick Tip: Incorporating at the wrong time can cost you more in accounting fees than you save in taxes. Read this guide first—then book a free consultation to confirm if it’s right for your situation.
🏢 What Is Incorporation, Exactly?
When you incorporate, you create a new legal entity—a corporation—that is separate from you as an individual. Your business is no longer “you.” It’s its own legal person with its own bank accounts, tax returns, liabilities, and rights.
Before incorporation: You are the business. If the business is sued, your personal assets (home, savings, car) are at risk.
After incorporation: The corporation is the business. In most cases, your personal assets are protected from business liabilities.
Two Main Types of Incorporation in Canada:
| Type | Who It’s For | Key Benefit |
|---|---|---|
| Federal Incorporation | Businesses operating across multiple provinces | Name protection across Canada |
| Provincial Incorporation (Ontario) | Businesses operating mainly in Ontario | Lower cost, simpler process |
For most small businesses in Richmond Hill, Ontario provincial incorporation is the most practical and affordable starting point.
📊 Sole Proprietorship vs Corporation: Side-by-Side Comparison
| Factor | Sole Proprietorship | Corporation |
|---|---|---|
| Tax Rate | Personal rate (up to 53.53%) | 12.2% on first $500,000 (Ontario CCPC) |
| Liability | Unlimited personal liability | Limited to business assets |
| Tax Filing | T1 + T2125 | T2 (separate return) + personal T1 |
| Income Splitting | Very limited | Possible via dividends/salary to family |
| CPP Contributions | Pay both employee + employer share | Pay both shares on salary only |
| Credibility | Seen as smaller / less formal | More professional image |
| Lifetime Capital Gains Exemption | Not available | Up to $1,250,000 when selling shares |
| Accounting Costs | Lower | Higher (worth it at the right income level) |
💰 The #1 Reason to Incorporate: Tax Savings
The biggest financial benefit of incorporation is the massive difference in tax rates.
Real-World Example:
You earn $200,000 in business profit.
- As a sole proprietor: Pay personal tax at ~50% = ~$100,000 in tax
- As a corporation: Pay 12.2% corporate tax = ~$24,400 in tax on retained earnings
- Difference: $75,600 stays in your corporation to reinvest, grow, or invest
💡 Important Clarification: The tax savings above apply to money left inside the corporation. When you eventually pay yourself that money as salary or dividends, you’ll pay personal tax. Incorporation is a tax deferral and planning tool, not a way to avoid tax entirely—but the deferral itself is extremely powerful for reinvestment.
✅ 7 Signs You’re Ready to Incorporate
1. Your Net Business Income Exceeds $100,000
This is the most common trigger point. Once your business is generating more profit than you need for personal living expenses, you’re leaving serious tax savings on the table as a sole proprietor.
Why $100,000? At this income level, the gap between personal tax rates (~43%) and the small business corporate rate (12.2%) becomes large enough that the added accounting costs of running a corporation are easily justified.
✅ Rule of thumb: If your business earns more than you personally need to spend, incorporate. The excess profit can compound inside the corporation at a much lower tax rate.
2. You Want to Protect Your Personal Assets
Are you in a field where lawsuits are a real risk—construction, consulting, real estate, healthcare, or professional services? As a sole proprietor, a single lawsuit or unpaid debt can threaten your home, savings, and personal finances.
Incorporation creates a legal wall between you and your business liabilities. If the business is sued, creditors can generally only go after the corporation’s assets—not yours.
⚠️ Note: Liability protection is not absolute. If you personally guarantee a loan, or if fraud or personal negligence is involved, courts can “pierce the corporate veil.” Always consult a lawyer alongside your accountant.
3. You’re Retaining Earnings to Reinvest in the Business
If you’re putting money back into your business—buying equipment, hiring staff, building inventory, or scaling operations—a corporation is far more efficient. Money retained inside a corporation is taxed at just 12.2%, leaving much more capital available to grow with.
Example: You want to reinvest $50,000 back into your business.
- Sole proprietor: Earn $50,000, pay ~$25,000 in tax, reinvest $25,000
- Corporation: Earn $50,000, pay ~$6,100 in tax, reinvest $43,900
4. You Plan to Bring In Partners or Investors
A corporation makes it significantly easier to structure ownership. You can issue different classes of shares, bring in investors, and define ownership percentages clearly and legally. A sole proprietorship has no clean mechanism for this.
If you ever plan to raise capital, sell part of your business, or bring on a business partner, incorporating now saves a complex restructuring later.
5. You Want to Sell Your Business One Day
This is one of the most overlooked reasons to incorporate early. When you sell the shares of a Canadian-Controlled Private Corporation (CCPC), you may qualify for the Lifetime Capital Gains Exemption (LCGE)—up to $1,250,000 completely tax-free as of 2024.
If you’re a sole proprietor and sell your business assets, no such exemption is available.
💰 Tax Savings Example: Sell your corporation’s shares for $1,250,000 in gain = $0 in tax (if LCGE conditions are met). As a sole proprietor selling assets? You’d owe hundreds of thousands in taxes on the same gain.
6. Your Clients or Contracts Require It
Many government contracts, corporate clients, and professional procurement processes require or strongly prefer working with incorporated entities. If you’ve been losing contracts or opportunities because you’re unincorporated, that’s a clear signal.
Additionally, some professional regulatory bodies (accountants, engineers, lawyers) have their own rules about incorporation—check with yours.
7. You Want to Split Income with Family Members
Incorporation opens legitimate income-splitting strategies. If your spouse or adult children are shareholders, you may be able to pay dividends to family members in lower tax brackets, reducing your household’s overall tax burden.
💡 Important: The Tax on Split Income (TOSI) rules introduced in 2018 have significantly restricted income splitting. This strategy requires careful planning—don’t attempt it without professional advice.
❌ When You Should NOT Incorporate (Yet)
Incorporation is not always the right answer. Here’s when it makes more sense to stay as a sole proprietor for now:
- Your income is under $80,000–$100,000 and you spend most of it personally. The accounting costs outweigh the tax savings.
- You’re just starting out and your income is unpredictable. Build your client base first.
- Your business is a side hustle that may not continue long-term.
- Your business is in early losses. Corporate losses are harder to use personally than sole proprietor losses, which directly offset your personal income.
- Your industry has minimal liability risk and you don’t need asset protection.
⚠️ Common Mistake: Many new business owners incorporate right away thinking it’s automatically better. Then they spend $1,500+ a year on corporate accounting for a business earning $40,000. Run the numbers first.
💸 What Does Incorporation Cost?
| Cost Item | Ontario Provincial | Federal |
|---|---|---|
| Government filing fee | ~$360 (online) | ~$200 (online) |
| Legal/accounting setup | $500–$1,500 | $500–$1,500 |
| Annual corporate tax return (T2) | $1,000–$2,500/year depending on complexity | |
| Annual corporate maintenance | $200–$500/year (minute book, annual resolutions) | |
✅ The Math: If incorporation costs you an extra $2,000/year in accounting but saves you $15,000+ in taxes, it’s a 650% return on investment. At BooBoo Accounting, we make sure incorporation only makes sense when the numbers work in your favour.
📋 What Happens After You Incorporate?
Incorporating is just the beginning. Once your corporation exists, here’s what you need to stay on top of:
1. Open a Corporate Bank Account
Your corporation must have its own bank account, completely separate from your personal finances. Mixing funds is a red flag for the CRA and undermines your liability protection.
2. Register for a Business Number (BN)
The CRA will assign your corporation a 9-digit Business Number used for all tax accounts (corporate income tax, HST/GST, payroll).
3. Register for HST/GST (If Required)
If your corporation’s revenue exceeds $30,000 in any 12-month period, you must register for HST/GST. Many businesses register voluntarily from day one.
4. Decide How to Pay Yourself
One of the most important decisions post-incorporation is how to compensate yourself—salary, dividends, or a combination. Each has different tax implications for both you and the corporation.
💡 Pro Tip: There’s no one-size-fits-all answer to salary vs. dividends. The optimal mix depends on your personal income needs, RRSP room, CPP goals, and corporate cash flow. This is exactly where a good accountant pays for themselves.
5. Maintain a Corporate Minute Book
A minute book is the official record of your corporation’s key decisions—shareholder meetings, director resolutions, share issuances. It’s a legal requirement in Ontario and must be kept up to date.
6. File Annual Corporate Tax Returns (T2)
Your corporation must file a T2 return within six months of its fiscal year-end, every year—even if it earned no income.
🗓️ Incorporation and Tax Deadlines to Know
| Obligation | Deadline |
|---|---|
| T2 Corporate Tax Return | 6 months after fiscal year-end |
| Corporate Tax Payment (CCPC) | 3 months after fiscal year-end |
| Corporate Installments (if tax > $3,000) | Quarterly throughout the year |
| T4 Slips (if paying salary) | February 28 each year |
| T5 Slips (if paying dividends) | February 28 each year |
| HST/GST Returns (if registered) | Monthly, quarterly, or annually |
| Personal Tax Return (T1) | April 30 (payment) / June 15 (self-employed filing) |
🎯 Key Takeaways
- Incorporation is a powerful tool—but only at the right time. The sweet spot is generally when net business income exceeds $100,000.
- The tax savings can be enormous. The small business corporate rate of 12.2% vs. personal rates up to 53.53% is the core advantage.
- Liability protection is a major benefit, especially for businesses in higher-risk industries.
- Plan for the exit. Incorporating early maximizes your chances of qualifying for the $1,250,000 Lifetime Capital Gains Exemption when you sell.
- Incorporation comes with responsibilities: corporate returns, minute books, payroll, and more. Make sure you have the right support.
- Don’t incorporate too early. For businesses under $80,000 in net profit, the added costs often outweigh the benefits.
- Always model the numbers before deciding. Every business situation is different—what works for your neighbour may not work for you.
