Side Hustle Taxes Canada 2026: What to Track, Set Aside and Report

Quick answer

Side hustle income in Canada is taxable — there is no minimum threshold below which you can ignore it. Every dollar of net self-employment income you earn (revenue minus business expenses) is added to your total income for the year and taxed at your marginal rate. If your day job pays $80,000 in Ontario, your marginal rate is roughly 33.89% — meaning each additional side hustle dollar is taxed at that rate, plus CPP contributions on the self-employed portion.

The good news: self-employed Canadians can deduct legitimate business expenses, lowering the net income that gets taxed. The key categories are home office (if you work from home), vehicle use (if business-related), equipment, software, marketing, and professional fees. Understanding what you can deduct can reduce your effective tax on side income by 20–40%.

How CRA treats side hustle income

CRA distinguishes between hobby income and business income:

• Business income: You have a profit motive, repeat activity, and market your services or products. This is reported as self-employment income and allows deductions. You also pay CPP contributions on net earnings over $3,500.
• Hobby income: You do it for pleasure without a consistent profit motive. CRA may treat it as taxable income anyway — without allowing business deductions. Keep records showing your profit intention if challenged.

Common side hustles: freelance design, writing, tutoring, food delivery, Airbnb rentals, e-commerce (Etsy, eBay, Shopify), consulting, and photography. All of these generate business income if operated with a profit intention.

The CPP self-employment trap

This surprises many first-time side hustlers: as a self-employed person, you pay boththe employee and employer share of CPP contributions. In 2026:

If you also have a day job where CPP is already deducted at the employee rate, you may already be near the CPP maximum from your employment income. In that case, additional side hustle income may have reduced CPP owing — your accountant's software or CRA's tax calculator handles this. But if your side hustle is your primary income or you have no employer deducting CPP, expect to pay the full 11.9% self-employed rate on net self-employment earnings above $3,500.

Deductions that reduce side hustle tax

GST/HST: when you must register

Once your side hustle gross revenue exceeds $30,000 in any 12-month period, you are required to register for GST/HST and charge it on applicable sales. In Ontario, HST is 13%. You must then remit HST collected minus HST you paid on business expenses (input tax credits).

Many side hustlers voluntarily register early to claim input tax credits on equipment and software purchases — this can recover $1,000–$2,000 in HST in the first year for someone who purchased a laptop, software subscriptions, and supplies. Registration does not affect the income tax treatment of your side hustle — it only applies to the HST collected and remitted.

Bottom line

Side hustle income in Canada is taxed at your marginal rate — and if your day job is in the $70,000–$100,000 range in Ontario, that rate is 33–43%. Self-employment also triggers CPP contributions at 11.9% (both sides). The mitigation strategy is simple: track every legitimate business expense (home office, equipment, software, marketing), use an RRSP contribution to offset the tax spike from a strong side-hustle year, and register for HST if approaching $30,000 gross revenue to recover input tax credits. For Canadians earning $5,000–$30,000/year in side income, keeping clean records and working with an accountant for the first return typically saves more than the accountant costs.
