Day Trading
Taxes
Canada
What active Canadian traders owe the CRA — and why most are taxed at 100%, not 50%.
The CRA’s position on day trading taxes is clear, and most Canadians who trade actively are surprised by it: your profits are almost certainly taxed as business income, not capital gains.
That’s a meaningful distinction. Capital gains are only 50% taxable in Canada. Business income is 100% taxable at your marginal rate. For someone in a 40% tax bracket, the difference on a $20,000 trading profit is $4,000 in additional taxes.
Getting this wrong — or ignoring it — is one of the most expensive mistakes Canadian day traders make. Here’s the framework you need.

What the CRA Looks At
How the CRA Classifies Day Trading Income
The CRA doesn’t have a single rule that says “X trades per year = business income.” Instead, it applies a facts-and-circumstances test based on several factors:
Frequency of trading: The more often you trade, the more likely the CRA is to classify your activity as a business. Intraday traders almost always fall into this category.
Holding period: Short holding periods — hours, minutes — signal speculative intent rather than investment intent. The CRA views this as a hallmark of business activity.
Primary purpose: If you buy securities with the intention of selling quickly at a profit (rather than holding for dividends or long-term growth), that’s a business purpose.
Time and knowledge devoted to trading: Traders who study charts, use technical analysis, and devote significant time to their activity are more likely to be classified as carrying on a business.
Use of leverage or borrowed money: Trading on margin adds another indicator of business activity in the CRA’s analysis.
The CRA’s Interpretation Bulletin IT-479R outlines these factors. The conclusion for most active day traders is the same: your gains will be treated as business income.

| Tax Treatment | Taxable Portion | Who It Applies To |
|---|---|---|
| Business income | 100% of net profit | Most active day traders |
| Capital gains | 50% of net profit (inclusion rate) | Passive investors, infrequent sellers |
Example: You earn $30,000 net from day trading in 2026, and your marginal tax rate is 43%.
- As business income: $30,000 × 43% = $12,900 in tax
- As capital gains: $15,000 (50% inclusion) × 43% = $6,450 in tax
The difference is $6,450 — simply from how the CRA classifies your activity. That’s why classification matters so much.
What Expenses Can Day Traders Deduct?
The good news about being classified as carrying on a business: you can deduct legitimate business expenses.
Deductible expenses for Canadian day traders typically include:
Trading platform fees: Subscription fees for trading platforms, Level 2 data, and charting software are deductible.
Commissions: Trading commissions paid to your brokerage reduce your net trading income.
Home office expenses: If you trade from a dedicated home workspace, a proportional portion of rent, utilities, and internet costs may be deductible.
Education and research: Courses, books, financial data subscriptions, and market research directly related to your trading activity.
Computer and equipment: A proportional deduction for computers, monitors, and hardware used for trading.
Keep detailed records of all expenses — the CRA can request receipts. Many active traders use dedicated accounting software or work with a tax professional who has experience with trading income.
How to Report Day Trading Income on Your Tax Return
Canadian day traders who are classified as carrying on a business report their trading income on Form T2125 — Statement of Business or Professional Activities.
The key lines:
- Gross income: Total proceeds from all sales (before subtracting what you paid)
- Cost of goods sold (adjusted cost base): The total amount you paid for the securities you sold
- Net income: Gross income minus cost of goods sold minus deductible expenses
Your net trading income from T2125 flows to line 13500 of your T1 General tax return and is added to your other income sources (employment, rental, etc.).
Tracking your adjusted cost base (ACB): The ACB is your average cost per share across all purchases of a given security. Canadian tax law requires you to track ACB using the average cost method (not FIFO or LIFO). Tools like ACB.ca and some brokerage statements help with this calculation.
Day Trading in a TFSA or RRSP: Tax Risks
Both accounts can hold stocks and ETFs — but active day trading inside a registered account creates serious CRA risk.
TFSA risk: The CRA has audited and reassessed TFSA accounts it determines are being operated as businesses. If your TFSA shows patterns of frequent trading and rapid profit-taking, the CRA can deem all gains taxable and eliminate your tax-free status retroactively. Several Tax Court of Canada decisions support this position.
RRSP risk: RRSP withdrawals are fully taxed as income regardless of how the money was earned. Day trading inside an RRSP eliminates the capital gains advantage (which doesn’t apply to RRSP withdrawals anyway) and introduces the same CRA reassessment risk as TFSAs.
The practical takeaway: keep active day trading in a non-registered account. Use your TFSA and RRSP for long-term, buy-and-hold investments where the accounts’ benefits are maximised.

Day Trading Tax Calculator Tips
There’s no single CRA-approved day trading tax calculator — the calculation depends on your specific income, province, and expenses. But you can estimate your tax exposure using a few steps:
- Calculate your net trading profit: Total proceeds minus total cost of securities sold minus trading commissions.
- Add deductible business expenses: Subtract platform fees, data subscriptions, home office costs, etc.
- Add to your other income: Combine your net trading income with employment income, rental income, and any other sources.
- Apply federal and provincial rates: Canada’s marginal tax rates are combined federal + provincial. In 2026, the top federal rate is 33% on income over ~$253,000. Most provinces add 10–17%.
A tax professional experienced with trading income will save you money — both by ensuring you claim every eligible deduction and by structuring your activity correctly. The CRA’s guide to investment income is the authoritative starting point.

Frequently Asked Questions
Is day trading income taxed as capital gains in Canada?
Usually not. The CRA treats most active day traders as carrying on a business, which means 100% of profits are taxable as business income rather than the 50% inclusion rate that applies to capital gains. Infrequent sellers who hold securities for longer periods are more likely to receive capital gains treatment.
What’s the tax rate on day trading in Canada?
Day trading income is taxed at your marginal income tax rate, which combines federal and provincial rates. In 2026, combined rates range from roughly 20% at low income levels to over 50% in high-income brackets in some provinces (Ontario’s top combined rate is approximately 53.5%).
Can I deduct trading losses?
Yes. Business losses from day trading can be deducted against other income sources (employment income, rental income, etc.) in the same tax year. Unused business losses can be carried back three years or forward 20 years. Capital losses, by contrast, can only be applied against capital gains.
Do I need to report foreign currency gains?
Yes. The CRA requires you to report gains and losses from foreign currency transactions, including USD-denominated securities held in Canadian accounts. All amounts must be converted to CAD using the Bank of Canada’s exchange rate at the time of the transaction.
How does the CRA know I’m day trading?
Brokerages are required to report certain transactions to the CRA. Beyond that, CRA data-matching programs compare T-slips and investment account activity. Undisclosed trading income is a CRA audit trigger. Always report accurately.
