Paying your 2017 taxes owing

When filing your return, you may have a balance owing on line 485. Generally, if this amount is $2 or less for 2017, you do not have to make a payment.

If you owe tax for 2017, and you file your 2017 return after the filing due date, we will charge a late-filing penalty.

We start charging compound daily interest on any outstanding balance for 2017 starting May 1, 2018, until you pay it in full.

For information about your account balance and payments, see My Account.


If you filed your return and have received your notice of assessment showing a balance owing, see Paying arrears.

Payment methods

You can make your payment in several ways. See Make a payment.

Important dates

  • You can pay your outstanding balance before you file your return. If you do, specify the year to which you want the payment applied. When you complete your return, claim this amount on line 476. As long as you file your return by the filing due date and pay by April 30, 2018, we will not charge you interest or a late-filing penalty.
  • You can file your return before the filing due date and make a post-dated payment. As long as you file your return by the filing due date and pay by April 30, 2018, we will not charge interest on your balance owing.
