Prior-year tax return packages
Many of the CRA forms and guides are frequently updated, sometimes every year, because of important changes for that year.
The 3 most common reasons you would use a form or publication for a previous year are:
- to file an original tax return for a previous year
- to ask for an adjustment to a previous-year's tax return that you've already filed (do not file another return for that year)
- to declare income under the Voluntary Disclosures Program
See Tax packages for all years to get current and prior year tax packages.
See forms and publications to search for other prior-year documents.
If the form or publication for the year you need is not on the list, use the current version.
