How multi-hustle taxation works in Canada

Every dollar of self-employment revenue you make flows through Form T2125 (Statement of Business or Professional Activities) on your personal T1 return. The CRA does not care if you did rideshare, tutoring, or bookkeeping — all of your self-employment net profits are pooled together to determine your taxable income.

Crucially, Canada Pension Plan (CPP) contributions are also calculated on this pooled amount. Self-employed Canadians pay both the employer and employee portions of CPP (totaling 11.9% in 2026), making self-employment pension costs one of the biggest tax liabilities side hustlers encounter.

The actual-cost vehicle rule (No flat per-km rates)

Unlike the US IRS, which allows a simple flat rate per mile, the CRA does not permit self-employed individuals to claim employee allowance rates ($0.73/km in 2026).

To deduct motor vehicle expenses for business, you must track your actual vehicle expenditures (fuel, insurance, license/registration fees, repairs, lease costs, or Capital Cost Allowance depreciation) and multiply that total by your **business-use ratio** (business kilometres driven divided by total kilometres driven in the calendar year). Our calculator applies this exact formula globally across all your stacked hustles.

The $30,000 GST/HST small supplier limit

If your gross self-employment revenues across **all** your side hustles and business activities exceed $30,000 over 4 consecutive calendar quarters, you are no longer considered a "small supplier." Under CRA rules, you must register for a GST/HST account, begin collecting tax from your clients, and remit it to the government.

The calculator automatically monitors your combined gross income and alerts you when you cross this threshold so you can stay in perfect compliance.

These are estimates, not official tax advice. Marginal income tax estimates are calculated based on single-filer rates and incorporate the 2026 Basic Personal Amount (BPA) non-refundable tax credit. Actual liabilities will depend on your final personal deductions, credits, and overall tax scenario. Always consult a CPA for filing advice.

Frequently asked questions

How does the Canadian side hustle tax calculator work?
Enter each side hustle separately — rideshare, freelance design, consulting, Etsy shop, or gig work. For each hustle, input your monthly flat income (or hourly rate), monthly business expenses, and monthly business kilometres. The calculator annualizes everything, stacks your income streams, deducts general business expenses, applies the CRA actual-cost vehicle expense deduction, and computes your 2026 CPP/QPP self-employed pension contributions, federal marginal tax, and provincial marginal tax based on your selected region.
Why isn't there a flat per-kilometre mileage deduction option?
Unlike the US IRS, the Canada Revenue Agency (CRA) does NOT allow self-employed individuals to deduct a flat per-kilometre rate (such as the $0.73/km employee reimbursement rate) for business travel. Instead, self-employed Canadians must claim actual vehicle costs (fuel, insurance, repairs, lease payments) multiplied by their business-use ratio (business km divided by total km). We designed this calculator to strictly follow the CRA T4002 guide to prevent disallowed audits.
What are CPP and CPP2, and how are they calculated?
As a self-employed Canadian, you are responsible for both the employer and employee portions of the Canada Pension Plan (CPP) contributions on your net self-employment earnings. For 2026, the base CPP rate is 11.9% on earnings between the $3,500 basic exemption and the Year's Maximum Pensionable Earnings (YMPE) of $74,600. In addition, the enhanced CPP2 contribution of 8.0% applies to earnings between the $74,600 YMPE and the Year's Additional Maximum Pensionable Earnings (YAMPE) of $85,000. If you are in Quebec, the Quebec Pension Plan (QPP) rate of 12.6% is used instead.
How does 'Other Income' affect my side hustle tax?
Canada uses a progressive tax bracket system. If you have a primary T4 job earning $50,000, your side hustle income starts taxing at the progressive brackets above $50,000 rather than from zero. Entering your 'Other Annual Income' allows the calculator to accurately determine which marginal tax brackets (both federal and provincial) your side hustle earnings will actually fall into.
When do I need to register for GST/HST?
Under CRA guidelines, if your gross self-employment earnings across all your side hustles and small businesses exceed $30,000 in a single calendar quarter or over four consecutive calendar quarters, you are no longer considered a 'small supplier.' You must immediately register for a GST/HST account and begin charging, collecting, and remitting sales tax on your taxable sales.
Do I need to pay quarterly tax installments to the CRA?
Yes, if your net tax owing to the CRA (income tax + CPP) is more than $3,000 for the current year AND has been more than $3,000 in either of the two previous years ($1,800 for Quebec residents). The CRA expects installment payments four times a year: March 15, June 15, September 15, and December 15. The calculator provides your estimated quarterly installment based on your total self-employment tax liability.
