Starting a small business in Canada is exciting, but understanding your tax responsibilities is critical for long-term success. One common question among new entrepreneurs is: “How much can my small business earn before I have to start paying taxes?” The answer depends on several factors, including the type of business structure you choose, your province, and your income level.
Let’s break it down so you can be prepared and make informed financial decisions.
Business Structure Matters
Your business structure significantly affects when and how you pay taxes in Canada. Most small businesses operate as either sole proprietorships, partnerships, or corporations.
- Sole proprietorships and partnerships: Your business income is reported on your personal income tax return. There’s no specific “tax-free” threshold for business income itself, but the basic personal amount (federally set at $15,705 for 2024) means you won’t pay federal tax until your total income—including business income—exceeds that amount.
- Incorporated businesses: If you’ve set up a corporation, the company is considered a separate legal entity. Corporations are taxed on their profits, not on the owner’s personal income. Corporate income tax applies regardless of how much profit you earn, even if it’s just $1.
That’s why it’s so important to work with a small business tax accountant Toronto entrepreneurs trust—especially if you’re unsure how to classify your income and deductions.
What Is the Basic Personal Amount?
Every Canadian taxpayer benefits from a basic personal amount (BPA). In 2024, the federal BPA is $15,705, and provincial amounts vary. If you’re a sole proprietor, you can earn up to this amount before owing federal income tax, though you still need to file a tax return.
Keep in mind: the BPA applies to total income, so if you have additional sources like employment or rental income, your business profits might be taxable even if they’re relatively low.
GST/HST Thresholds for Small Businesses
In addition to income tax, small businesses must also consider GST/HST registration. If your total revenues (before expenses) exceed $30,000 in any 12-month period, you are required to register for a GST/HST number and begin charging sales tax.
Even if you don’t hit the threshold, registering voluntarily can allow you to claim Input Tax Credits (ITCs) on your business expenses, which might be beneficial depending on your cash flow and purchases.
What About Corporate Small Businesses?
If your small business is incorporated, it’s subject to corporate tax from day one. However, many small Canadian-controlled private corporations (CCPCs) qualify for the small business deduction (SBD), which lowers the corporate tax rate on the first $500,000 of active business income to around 9-15%, depending on your province.
While this is a great tax break, filing corporate taxes is more complex. Accurate bookkeeping, timing of income recognition, and expense management become essential. This is where an experienced small business tax accountant can save you thousands of dollars and hours of time.

- Track your income regularly to stay aware of the $30,000 GST/HST threshold
