In some cases, you must subtract certain contributions and deductions from the remuneration subject to source deductions of income tax.

For each pay period, reduce an employee's gross remuneration by subtracting:

• registered pension plan (RPP) contributions;
• contributions to a registered retirement savings plan (RRSP), a voluntary retirement savings plan (VRSP) or a pooled registered pension plan (PRPP) that you withhold and remit directly to the plan administrator;
• contributions to a retirement compensation arrangement that you withhold and pay to the retirement compensation arrangement;
• the deduction for the purchase of shares in a labour-sponsored fund;
• the Cooperative Investment Plan (CIP) deduction;
• the travel deduction for residents of designated remote areas;

  If an employee's remuneration for a pay period includes the value of a taxable benefit related to trips made by a resident of a designated remote area, you have to subtract from the employee's gross remuneration, for that pay period, the amount of the travel deduction the employee can claim in their income tax return in respect of the benefit.
  
  Before subtracting the amount, make sure that the employee meets the conditions for claiming the deduction. For more information, see Trips Made by a Resident of a Designated Remote Area.

  If you are paying remuneration as a payer, the beneficiary is not entitled to the deduction. Similarly, if you are paying remuneration that includes only a taxable benefit relating to previous employment, the employee is not entitled to the deduction. To ensure that the source deduction of income tax is not less than it should be, make the adjustment outlined in table TP-1015.TI-V.

  Starting January 1, 2023, you have to include the amount that represents an employee's additional contributions to the QPP when you determine what remuneration is subject to Québec income tax.

  The Formulas to Calculate Source Deductions and Contributions (TP-1015.F-V), the Source Deduction Table for Québec Income Tax (TP-1015.TI-V) and WebRAS for 2023 have been modified to include the amount.

  If you use table TP-1015.TI-V to calculate the Québec income tax that must be withheld, do not subtract the amount that represents the employee's additional contributions to the QPP from the employee's gross remuneration.The table already takes this amount into account.
