Line 22215 – Deduction for CPP or QPP Enhanced Contributions on Employment Income

On your Canadian income tax and benefit return, Line 22215 is used to claim a deduction for the enhanced contributions you made to the Canada Pension Plan (CPP) or the Quebec Pension Plan (QPP) on your employment income during the year. Enhanced contributions arise from amounts above the base CPP/QPP rate due to the CPP/QPP enhancement introduced in recent years.

📌 What Enhanced Contributions Are

Your CPP or QPP contributions consist of:

  • a base amount calculated under standard contribution rates;
  • a first additional amount based on pensionable earnings up to the Year’s Maximum Pensionable Earnings (YMPE);
  • a second additional amount for earnings above the YMPE but not more than the Year’s Additional Maximum Pensionable Earnings (YAMPE).

🧮 How to Calculate Your Deduction

To determine the amount to enter on Line 22215:

  • Use the totals from boxes 16, 16A, 17 and 17A on all your T4 slips for the year.
  • Complete Schedule 8 (Canada Pension Plan Contributions and Overpayment), or if you contributed to both CPP and QPP, use Form RC381 (Inter‑Provincial Calculation for CPP and QPP Contributions and Overpayments) to calculate the enhanced amount.
  • Carry the result to Line 22215 of your tax return.

💰 Maximum Deduction for 2025

Whether you contributed to CPP or QPP, the maximum amount you can claim on Line 22215 for 2025 is $1 074.00. This total consists of a maximum first additional amount of $678.00 and a second additional amount of $396.00, based on your pensionable earnings for the year.

The deduction applies only to contributions that exceed basic CPP/QPP amounts as calculated for enhanced pensionable earnings.

📥 What You Need

  • All your T4 slips showing CPP/QPP contributions (boxes 16, 16A, 17, 17A).
  • Schedule 8 or Form RC381 to perform the detailed calculation.
  • Your tax return where Line 22215 is located (generally in Step 3 – Net Income).

📌 Why This Deduction Matters

This deduction helps ensure that you receive tax relief for higher CPP/QPP contributions that result from the enhanced portions of the pension plans. Without it, your taxable income would be higher, even though you’ve already contributed more to your pension savings through payroll.

For most taxpayers, this benefit is calculated automatically if you use certified tax software and enter your T4 figures correctly. If you compute manually, follow the instructions on Schedule 8 or Form RC381.
