Hobby vs Business for Tax Purposes
The test CRA and the courts use to decide whether your activity is a business or a hobby, and why it matters.
The short version
- Canadian tax law has no dollar threshold that turns a hobby into a business. The question is whether you carry on the activity in pursuit of profit.
- If an activity has no personal or recreational element, it's generally a business. If it does (crafts, horses, music, photography, collecting), it must be run in a sufficiently commercial way to count.
- A business reports all its profit and can deduct its expenses and losses. A pure hobby isn't taxed, and its losses aren't deductible.
- Regularly selling things you make or buy to resell is usually a business, even if you enjoy it. Selling your own used belongings is usually not.
- CRA tends to raise the question when a "business" shows losses year after year against other income.
Hobby vs Business for Tax Purposes
Most people discover this question in one of two moods. Either the hobby started making money and they'd like it to stay invisible, or the hobby loses money every year and they'd like it to be a business. CRA has seen both moods. The rules don't care which way you lean; they look at how you actually run the thing.
The Test CRA and the Courts Use
The leading case is the Supreme Court of Canada's 2002 decision in Stewart v. Canada. It set a two-step approach:
- Is the activity undertaken in pursuit of profit, or is it a personal endeavour? If there's no personal or recreational element (renovation contracting, tutoring for pay, a cleaning service), the activity is commercial and it's a business. End of test.
- If there is a personal element, is it carried on in a sufficiently commercial manner? Here CRA and the courts look at objective evidence, not your intentions.
The factors usually weighed in step 2:
| Points toward a business | Points toward a hobby |
|---|---|
| A business plan, prices set to make a profit | No plan; prices that barely cover materials |
| Separate bank account, bookkeeping, receipts | Mixed personal and hobby spending |
| Active marketing: website, listings, markets, clients | Sales mostly to friends and family, when they ask |
| Training or experience in the field | No relevant background |
| Losses shrinking over time, or a change in approach when they didn't | Steady losses with no change |
| Regular time spent, like a job | Time spent when you feel like it |
| Registered for GST/HST, licences, a business name | None of the trappings of a business |
No single factor decides it. A potter with a business plan, an Etsy shop, a booth at three markets a year and a separate bank account is likely in business, even at a small scale. A potter who sells six mugs a year to coworkers probably isn't.
Is my side activity a business or a hobby?
Describe what you do, how you sell, what you earn and spend, and how long you've been at it. The assistant walks through the CRA factors and tells you which side you're likely on, and what to report.
What Changes Depending on the Answer
| Business | Hobby | |
|---|---|---|
| Profit | Taxable; reported on form T2125 | Generally not taxable |
| Expenses | Deductible against income | Not deductible |
| Losses | Deductible against other income; can carry over | Not deductible |
| CPP | Payable on net self-employment earnings above $3,500 | None |
| GST/HST | Register once you pass $30,000 in taxable sales (sooner for some) | Generally not |
That last row is worth a second look. A hobby that becomes a business also becomes a GST/HST question; see the GST/HST small supplier rule.
The Profitable Hobby
If your activity regularly makes money because you set out to make money, it's very likely a business, and the profit is taxable. "It's just a hobby" isn't a defence when there's a price list. The safer reading for most people: if you sell regularly, report it. The upside is you get to deduct the expenses. See side hustle taxes for what to report and business expense deductions for what you can take off.
And yes, selling online is now visible. Since 2024, digital platforms such as marketplaces and craft sites report many sellers' earnings to CRA each year under the reporting rules for digital platform operators.
The Money-Losing Hobby
This is where most disputes are. If you claim business losses from an activity with a personal element, expect CRA to ask for the evidence in the table above. Horse breeding, hobby farms, sailboat charters, music recording, photography and art are the classic examples. If CRA decides it's a hobby, the losses are reversed for every year still open to reassessment, with interest. See business losses for how losses work when they are allowed.
Farming has its own rule: when farming isn't your chief source of income, deductible losses can be restricted to $17,500 a year even if it is a business.
Artists and Writers
CRA has a specific folio for artists and writers (S4-F14-C1). It goes as far as accepting that an artist may never turn a profit and still be in business, if the work is run in a business-like way. It lists ten factors, including time spent, exhibitions or publications, representation by a dealer, agent or publisher, time spent marketing, training and awards, professional memberships, and whether revenue is growing. Keep the paper trail: submissions, applications, grants, sales records.
CRA says your business is a hobby?
If a reassessment denied your losses, you have 90 days from the notice date to object. The SmartFile organizes the commercial-manner evidence and drafts the objection.
Moving From Hobby to Business
- Pick a start date. CRA generally treats a business as starting when you begin significant activity that is a regular part of it, such as buying inventory or equipment to sell with.
- Open a separate account and start bookkeeping.
- Write down the plan: products, prices, where you'll sell, when you expect a profit.
- Note what you already own. Equipment you bring into the business can be added at its fair market value at that date and depreciated; see capital cost allowance explained.
- Set money aside for tax; see how much to save for taxes.
Already Missed a Few Years?
If the hobby turned into a business a while ago and nothing was reported, fixing it before CRA asks is cheaper. See how to change a tax return and unfiled tax returns.

Hobby vs Business Questions
How much can you make from a hobby before paying tax in Canada?
There is no dollar threshold. If the activity is a business, all its profit is taxable from the first dollar. Whether it is a business depends on whether you carry it on in pursuit of profit, not on how much you earn.
What is the difference between a hobby and a business for CRA?
A business is carried on in pursuit of profit. Where the activity has a personal or recreational element, it must also be run in a sufficiently commercial manner, judged by factors such as a business plan, records, marketing, training, time spent and profit history.
Can I deduct hobby losses on my tax return?
No. Losses are deductible only from a business. If CRA decides the activity is a hobby, it can deny the losses.
Is selling my own used items taxable?
Usually not. Selling your personal belongings for less than you paid is generally not income. Regularly buying items to resell, or making items to sell, is usually a business.
What court case decides hobby vs business in Canada?
Stewart v. Canada, a 2002 Supreme Court of Canada decision, sets the main test: whether the activity is undertaken in pursuit of profit, and, if it has a personal element, whether it is carried on in a sufficiently commercial manner.
