How Much Can a Small Business Make Before Paying Taxes? (Canada)

MyCarTracks_support · May 15, 2026, 10:44am

If you are asking how much a small business can make before paying taxes in Canada, the short answer is: do not rely on one tax-free business threshold. Business profit is generally part of your tax calculation, and guidance from the Canada Revenue Agency (CRA), the federal tax agency, on self-employment income tells self-employed people to report gross and net self-employment income, or loss, on the return.

The $30,000 GST/HST small supplier threshold is a goods and services tax/harmonized sales tax registration rule for taxable supplies, not an income-tax exemption. A business can owe income tax or Canada Pension Plan (CPP) contributions even when it is below that GST/HST threshold, and a business can need GST/HST registration before year-end depending on the one-quarter or four-quarter test.

This article is educational and is not tax, legal, accounting, payroll, GST/HST, Quebec sales tax (QST), or provincial tax advice. Tax results depend on your business structure, province or territory, other income, deductions, credits, GST/HST or QST status, payroll status, Canada Pension Plan (CPP) or Quebec Pension Plan (QPP) treatment, employment insurance (EI) choices, losses, and filing history. Ask an accountant before using a threshold to make a tax or registration decision.

Quick answer

There is no universal amount a Canadian small business can make before paying tax. Sole proprietors and self-employed people generally report business profit on their personal tax return. A corporation calculates corporation income tax separately. GST/HST uses taxable supplies and small supplier rules. CPP/QPP, EI, payroll, and instalments each have their own tests.

Use gross revenue to monitor GST/HST registration risk. Use net profit to estimate income tax and self-employed CPP/QPP. Use net tax owing to assess personal instalments. Use payroll paid and remitter type for employee deductions. Do not treat any one number as a tax-free business income limit.

How much a small business can make before paying taxes in Canada

For income tax, the better question is whether the business has taxable profit after supported expenses, and how that profit fits into the owner’s or corporation’s return. A sole proprietor with business profit reports it through the personal return. Partners report their share. A corporation files its own T2 corporation income tax return.

The CRA treats business income as income from activities carried on for profit or with a reasonable expectation of profit. Employment income is different. If you receive wages or salary from an employer, that is not business income just because you also run a side business.

If business expenses are higher than business income, the result may be a loss rather than taxable business profit. Loss handling depends on the type of business, the year, and the return. The CRA’s T4002 losses chapter covers self-employed loss treatment and when Form T1A, the request form for carrying back a loss, may be used to carry back a non-capital loss.

Gross income, net profit, taxable income, and taxable supplies

Keep these terms separate:

Term	What it means	Why it matters
Gross business income	Total business income before expenses	Starting point for records and return reporting
Net business income or profit	Business income minus deductible business expenses	Often the amount that feeds the income tax calculation
Taxable income	Income after applicable deductions and adjustments	Used to calculate income tax under the relevant return
Taxable supplies	Sales of goods or services subject to GST/HST rules	Used for GST/HST small supplier and registration tests
Net tax owing	Tax payable after credits and other adjustments	Used for individual instalment thresholds

Mixing those terms is how threshold mistakes happen. A business can have more than $30,000 in gross revenue but little profit. A business can have less than $30,000 in taxable supplies but still owe income tax. A business can have no employees but still owe self-employed CPP or QPP.

GST/HST small supplier threshold

Many businesses do not have to register for GST/HST while they remain small suppliers. Under the CRA’s when to register and charge GST/HST guidance, the general threshold for many businesses is more than $30,000 in taxable supplies in one calendar quarter or over the previous four consecutive calendar quarters.

Timing matters:

If you exceed $30,000 in one calendar quarter, you stop being a small supplier on the supply that made you exceed the threshold. Registration is generally due within 29 days of that supply, and you start charging GST/HST on that supply.
If you exceed $30,000 over four consecutive calendar quarters but not in one quarter, you generally stop being a small supplier at the end of the month after the quarter when you exceeded the threshold. Registration is generally due within 29 days after that day.
Taxi and commercial ride-sharing businesses have special GST/HST registration rules and should not rely on the general small supplier threshold.
Québec businesses may also need to review QST and Revenu Québec registration.

Voluntary registration can make sense for some businesses, especially when input tax credits matter, but it also creates filing, charging, remittance, and recordkeeping duties.

Income tax for sole proprietors and self-employed people

Sole proprietors, freelancers, contractors, and many self-employed people usually report business or professional income on the personal return. You calculate profit by subtracting supported business expenses from business income, then the personal tax return applies federal and provincial or territorial tax, credits, and other items.

Income tax does not wait for the business to become incorporated or pass the GST/HST threshold. If you have business profit, other income, or credits that change the calculation, your final tax result can change.

If you expect to owe tax without enough withholding, review individual instalments. The CRA’s required tax instalments guidance says you may have to pay instalments for next year’s taxes if your net tax owing is more than $3,000, or more than $1,800 for Québec, for 2026 and in either 2025 or 2024.

CPP, QPP, and EI for self-employed people

CPP and QPP are not the same as income tax. Outside Québec, self-employed people generally pay both the employee and employer portions of CPP on pensionable self-employment earnings. The CRA’s 2026 CPP figures list a $3,500 basic exemption, $74,600 maximum annual pensionable earnings, 5.95% employee and employer CPP rates, and a maximum self-employed CPP contribution of $8,460.90 before the second additional Canada Pension Plan contribution (CPP2).

CPP2 applies above the first earnings ceiling up to the second ceiling. For 2026, CRA’s CPP2 figures list $85,000 additional maximum annual pensionable earnings, a 4% employee and employer CPP2 rate, and a maximum self-employed CPP2 contribution of $832.

Québec uses QPP instead of CPP. If you live or work in Québec, check the QPP treatment that applies to your facts.

Self-employed EI is generally optional and relates to special benefits. It is not the same as employer EI payroll deductions for employees.

Taxes if you hire employees

Hiring employees creates payroll duties even if the business is small. You may need a payroll program account, TD1 forms, payroll deduction calculations, remittance due dates, and year-end slips.

For employees, review:

income tax withholding using CRA payroll tables
CPP or QPP deductions and employer contributions
EI premiums and employer contributions
payroll remitter type and due dates
records for salaries, wages, taxable benefits, source deductions, and remittances

Do not use the business’s profit or GST/HST threshold to decide whether payroll applies. Payroll starts from paying employees and the rules for that employee’s province or territory of employment.

What if the business makes no money or has a loss?

A business with no revenue or a loss may still have filing or recordkeeping obligations. You may need to report the activity, keep source documents, support expenses, and preserve the loss calculation. The CRA self-employment income page tells taxpayers to report gross and net self-employment income or loss on the return.

Losses are not a blank cheque. Keep records showing that the activity was business activity, which expenses were business-related, and how the loss was calculated. If a loss is material, repeated, or connected to assets, farming, fishing, partnerships, or a corporation, get professional advice before relying on it.

How to estimate whether you may owe

Use a simple workflow before tax time:

Add all business income by source: invoices, platforms, payment processors, cash, deposits, and contracts.
Separate business expenses from personal costs.
Identify current expenses, capital expenses, prepaid costs, and mixed-use allocations.
Calculate net profit before personal credits and instalments.
Check GST/HST taxable supplies separately from profit.
Estimate CPP or QPP and optional EI separately from income tax.
If you have employees, calculate payroll deductions using CRA tables.
Save records for each number you used.

For vehicle expenses, keep total kilometres, business kilometres, odometer readings, trip purpose, and receipts. CRA Mileage Log Requirements (Canada) explains the vehicle record side in more detail.

MyCarTracks workflow

If vehicle use affects your estimate, do not wait until tax time to rebuild the business/private split. MyCarTracks automatic mileage tracking can capture trips, help classify business and personal kilometres, and export reports for the same file you use to estimate profit, vehicle expenses, reimbursements, or accountant review.

The app does not decide whether you owe income tax, CPP/QPP, EI, GST/HST, payroll, instalments, or corporation tax. It helps keep the vehicle-record part of the estimate ready so the tax calculation starts from better kilometre data.

FAQ

Is the first $30,000 of small-business income tax-free in Canada?

No. The $30,000 figure is commonly associated with GST/HST small supplier rules for taxable supplies. It is not a general income-tax exemption for business profit.

Do I pay tax on gross revenue or profit?

Income tax generally starts from profit after supported business expenses, then the personal or corporate tax return applies the relevant deductions, credits, and rates. GST/HST registration uses taxable supplies, not profit.

Do I have to file if my small business made no money?

You may still need to report self-employment income or loss and keep records. The answer depends on your structure, activity, other income, loss position, GST/HST status, and filing obligations.

When do self-employed people pay instalments?

For individuals, CRA instalment rules can apply when net tax owing is more than $3,000, or more than $1,800 for Québec, for 2026 and in either 2025 or 2024. Instalment due dates are separate from GST/HST and payroll due dates.

Is self-employed EI mandatory?

Self-employed EI participation is generally optional for special benefits. Employee EI payroll deductions are different and apply when you have employees and insurable employment.
