Filing due dates for the 2017 tax return
Generally, your return for 2017 has to be filed on or before April 30, 2018.
If you do not file your return on time (see exception to the due date of your return), your goods and services tax/harmonized sales tax (including any related provincial credits), Canada child benefit payments (including related provincial or territorial payments), and old age security benefit payments may be delayed or stopped.
If you or your spouse or common-law partner carried on a business in 2017 (other than a business whose expenditures are primarily in connection with a tax shelter), your return for 2017 has to be filed on or before June 15, 2018. However, if you have a balance owing for 2017, you have to pay it on or before April 30, 2018. For more information on how to make your payment, see Make a payment.
Exception to the due date of your return
When the due date falls on a Saturday, a Sunday, or a public holiday recognized by the CRA, your return is considered on time if we receive it or it is postmarked on the next business day. For more information, see Important dates for Individuals.
If you are filing for a deceased person the due date may be different. For more information, see Guide T4011, Preparing Returns for Deceased Persons.
