Hi @action120747 

To add installment payments to your tax return you can enter on line 47600 of your tax return the total instalment payments you made for your taxes for the year.

The CRA will issue you Form INNS1, Instalment Reminder, or Form INNS2, Instalment Payment Summary, which shows your total instalment payments for the previous year that the CRA has on record. Log into your CRA My Account to see your instalment account. If you made an instalment payment for your taxes for the previous year that does not appear on this reminder or summary, also include that amount on line 47600.
