OTTAWA -- Five things to know when filing income tax returns this year:

Deadline: The deadline for most Canadians to file their income tax return is normally April 30, but because that falls on a Saturday this year, the Canada Revenue Agency will consider it on time if returns are submitted by May 2. If you or your spouse or common-law partner were self-employed last year, you have until June 15 to file. But if you owe money, you must still pay it by May 2.

Always file a return: Even people who have no income or only made a small amount last year and don't owe any tax should file an income tax return. They may be eligible for a refund or other benefits such as the goods and services tax/harmonized sales tax credit.

New this year: The Canada Revenue Agency is making it easier this year to prepare income tax returns. People are allowed to use a new auto-fill service to fill in tax information for 2015, depending on the software they use.

Changes: Were there any big changes in your life in 2015? Did you get married, have a child or maybe move across the country to take a new job? These could mean changes in your income tax return this year.

Need help?: People don't need to pay an accountant for help doing their tax returns. The Community Volunteer Income Tax Program has been helping Canadians with modest income and a simple tax situation prepare their tax returns for more than 40 years.
