Gratuities and retroactive pay

Deduction for employment income

For 2021, the maximum deduction for employment income is $1,205. The Source Deduction Table for Québec Income Tax (TP-1015.TI-V) takes the amount into account.

Emergency services volunteer

For 2021, the maximum exemption that can be granted to an emergency services volunteer is $1,205.

Disability assistance payments from an RDSP

For 2021, you must withhold income tax at a rate of 15% from the portion of a disability assistance payment from a registered disability savings plan (RDSP) that exceeds $19,220.

Tax credit for the acquisition of Fondaction shares

The rate for the tax credit for the acquisition of Fondaction shares has been 20% since June 1, 2015. This rate will decrease to 15% on June 1, 2021.

This means you will have to change the way you calculate income tax deductions on remuneration you pay an employee who authorizes you to withhold an amount for the purchase of class A or class B Fondaction shares for pay periods after May 31, 2021.

If you use the Source Deduction Table for Québec Income Tax (TP-1015.TI-V), you will have to subtract an amount equal to 75% (rather than 100%) of the amount withheld for the purchase from the employee's gross remuneration.

If you use the guide Formulas to Calculate Source Deductions and Contributions (TP-1015.F-V), you will have to subtract an amount equal to 15% (rather than 20%) of the amount withheld for the purchase from the income tax payable for the year.
