💰 T4037 – CRA Capital Gains Guide

📊 What Capital Gains and Losses Are

A capital gain arises when you sell or are considered to have disposed of capital property for more than its total cost (adjusted cost base plus selling costs). Conversely, a capital loss occurs when the disposition results in less than the cost.

Capital property generally includes investments like stocks, bonds, real estate (except your principal residence under certain conditions), and other investment properties.

📈 How to Calculate Capital Gain or Loss

  1. Proceeds of disposition: The total amount you received when you sold the property (or its fair market value).
  2. Adjusted cost base (ACB): Typically what you paid for the property plus transaction costs (commissions, fees).
  3. Outlays and expenses: Costs directly related to selling the property.

Formula:
Proceeds of disposition − (ACB + selling expenses) = the capital gain or loss.

Only 50 % of a capital gain (the inclusion rate) is generally taxable and included in income on your tax return.

📋 When to Report Gains or Losses

Report capital gains and losses on Schedule 3 of your Canadian tax return. Even if you did not receive a tax slip for some dispositions, you may still need to report them if the sale resulted in a gain or loss.

If your only capital gains or losses come from amounts on T3, T4PS, T5 or T5013 slips and you did not file forms like T664 (seniors election), you may not need to read the entire guide.

📍 Specific Situations Explained

Principal Residence

Your principal residence may be fully or partly exempt from capital gains tax when sold. Special reporting rules apply, and you might need to designate it accordingly on your return.

Small Business Shares

If you sell qualifying small business corporation shares, you may be eligible for the lifetime capital gains exemption, reducing taxable gains up to a limit.

Foreign Property or Foreign Gains

If you had investments outside Canada, convert gains and cost bases to Canadian dollars using exchange rates at acquisition and disposition dates. Report worldwide capital gains in your Canadian tax return.

🧾 Capital Losses and Carry‑Forward Rules

If your capital losses exceed your gains, you have a net capital loss that can be used to reduce capital gains in other years. You can generally carry capital losses back three years or forward indefinitely to offset capital gains.

📊 Types of Property and Examples

  • 📉 Stocks, mutual funds and bonds
  • 🏠 Rental and investment real estate
  • 🪙 Collectibles and personal property (subject to special rules)

For example, selling publicly traded shares for more than your adjusted cost base results in a capital gain, part of which is taxable.
