A capital gain is the profit from selling a capital asset, such as shares, real estate or a business, for more than its adjusted cost base.
When you sell a capital property for more than you paid, the difference is a capital gain. In Canada only a portion of a capital gain is taxable, the inclusion rate, rather than the whole amount. Historically the rate has been one-half, meaning half the gain is added to income and taxed at your normal rate.
Certain gains get special treatment. Your principal residence is generally exempt, and gains on qualifying small business corporation shares can be sheltered by the lifetime capital gains exemption, which shelters over $1.25 million per person. Capital losses can offset capital gains but generally not other income.
You buy shares for $20,000 and sell them for $50,000. Your $30,000 capital gain is subject to the inclusion rate, so a portion is added to your taxable income while the rest is received tax-free.
Our certified accounting firm handles this for businesses and individuals across Canada, at fixed fees with no surprises.

HST combines the 5% federal GST with a provincial component in five participating provinces. For 2026 the combined rates are 13% in Ontario, 15% in New Brunswick, Newfoundland and Labrador, and Prince Edward Island, and 14% in Nova Scotia since 1 April 2025. Elsewhere you charge the 5% GST alone, or GST plus a separate provincial tax. The rate follows the province of supply, not where your business sits.
A tax return is the annual filing that reports your income, deductions and credits to the CRA so the final tax for the year can be settled. Payers withhold tax during the year and the return reconciles that against what you actually owe, producing either a refund or a balance to pay. For 2025 returns filed in 2026, refunds usually arrive in about two weeks for an online return, while a paper return runs on a considerably longer standard because it is handled manually.
Tax exempt describes an amount or a transaction that tax does not apply to at all, which is different from a deduction or credit that merely reduces tax. Common examples are supplies that are exempt or zero-rated for GST/HST, investment income earned inside a TFSA, and specific receipts Parliament has excluded from income. Registered charities and non-profits can be exempt from income tax while still carrying filing duties. Exemption is never automatic; the rule must fit your facts.
A T4E is the slip Service Canada issues for Employment Insurance and certain related benefits. It shows the total benefits paid, income tax already withheld, any benefits you had to repay and any benefit repayment required because of your income level. Report the amounts on your personal return on the line for Employment Insurance and other benefits, not on the employment income line — EI benefits are taxable but they are not employment income. Keep the slip even where no tax was withheld, because the benefits remain taxable and the CRA already holds a copy.
