📊 Chart 4 – Applying Net Capital Losses of Other Years

The Chart 4 – Applying Net Capital Losses of Other Years is used when completing your Canadian income tax and benefit return to determine how much of your previous years’ net capital losses you can apply to reduce your taxable capital gains.

This calculation helps determine the deduction you can claim on line 25300 – Net capital losses of other years. Applying these losses can reduce your taxable income for the current year.

💡 What is a Net Capital Loss

A net capital loss occurs when your allowable capital losses exceed your taxable capital gains in a tax year. These losses can be used to:

• ⬅️ Offset capital gains from the previous 3 years
• ➡️ Carry forward to any future year

However, net capital losses generally can only reduce taxable capital gains — not other types of income.

📋 When to Use Chart 4

You should complete Chart 4 if:

• You do not have unused capital losses from before May 23, 1985
• Your Notice of Assessment shows unused net capital losses
• You had a net capital loss in the previous tax year

If you have losses from before May 23, 1985 or need a detailed breakdown by year, you must instead use another calculation method (Chart 5).

🧾 Step-by-Step: How Chart 4 Works

The chart calculates the amount of capital losses that can be applied to the current tax year.

Step 1 — Determine available losses

• Enter your unapplied net capital losses from previous years.
• Add your net capital loss from the previous tax year.

These values usually appear on your Notice of Assessment or Reassessment.

Step 2 — Calculate total available losses

Add the two amounts together to determine your total available capital losses.

Step 3 — Compare with current taxable gains

• Enter your taxable capital gains (line 12700).
• The amount you can claim cannot exceed those gains.

Step 4 — Choose the deduction

Enter the amount of loss you want to apply against your gains for the year. This amount is claimed on line 25300 of your tax return.

Step 5 — Carry forward remaining losses

Any unused amount becomes a balance of net capital losses that you can carry forward to future tax years.

📊 Example Calculation

Remaining losses available to carry forward: $4,000.

⚠️ Important Rules

• 📉 Capital losses must be applied against capital gains only.
• 📅 Older losses must be used before newer ones.
• 📊 Losses may need adjustment if the capital gains inclusion rate changed.
• 📄 The deduction is reported on line 25300 of your tax return.
