Managers:  TD1’s should be filled out for ALL employees each year.  You can print them from here: http://www.cra-arc.gc.ca/formspubs/frms/td1-eng.html

Employees:  If you are employed full time and have other income that is not taxed – such as self-employed or dividends – consider an extra deduction of income tax from your employment income so you don’t end up having to pay when you file.
