For most Canadians, the deadline to file a personal income tax return is April 30. If you owe tax and miss this deadline, CRA charges a late-filing penalty plus interest on any balance owing. If you or your spouse or common-law partner are self-employed, you have until June 15 to file your return. However, any taxes owed are still due by April 30. You should always file on time even if you do not owe tax. Filing late can delay your GST/HST credit, Canada Child Benefit, and other payments. RRSP contributions for the previous tax year must be made by the first 60 days of the new year. Most Canadians file using NETFILE-certified tax software. CRA also offers free filing options for simple returns.
