You can choose to have more tax deducted from the remuneration you receive in a year. To do this, you have to file a new federal Form TD1, that shows how much more tax you want deducted. This amount stays the same until you file a new Form TD1.

Part-time employees are advised that it could be beneficial to have more income tax deducted from the remuneration they receive by completing Form TD1. By doing this, they can avoid having to pay a large amount of tax when they file their income tax and benefit returns, especially if they have worked part-time for different employers during the year.
