For most Canadians, the deadline to file your tax return is April 30 each year. If you or your spouse are self-employed, the filing deadline is June 15 - but any balance owing is still due April 30. Gather your tax slips. Most arrive by the end of February. Common ones include: - T4 - employment income - T5 - investment income - T4A - pension, retirement, or other income - T2202 - tuition (for students) - RRSP contribution receipts CRA's NETFILE system lets you file electronically using certified tax software. You can also file by paper, but electronic filing is faster. CRA processes your return and sends a Notice of Assessment (NOA). Keep your NOA - it shows your RRSP contribution room for next year. It's worth filing even with zero income. Filing qualifies you for the GST/HST credit and Canada Child Benefit. Note: RRSP contribution room comes from earned income, not from filing itself - if you had no earned income, no new RRSP room is created. CRA offers a free Community Volunteer Income Tax Program (CVITP) for people with simple tax situations and modest income.
