From the Interview section ‘CRA questions’, you answer ‘Yes’ to ‘did you sell a principal residence in 2020’ and click on ‘designation’. This will open the capital gains forms menu, scroll down to ‘personal use’ and click on (+). You are now in the section which will generate the T2091 and TP-274 (Québec) forms. Give the property a name and complete dates (2007 to 2020), price sold, and other requested info ACB (FMV+costs to maintain). As you enter property information, keep an eye on the ‘messages’ window below for errors or warnings.
Under ‘designation’ from 2007 to 2017. The next line will ask you for change of use under articles 284 - 286 this is probably ‘No’, but study this line carefully.. When the return is generated, inspect forms T2091 TP274 to make sure they are filled correctly. You will need a realistic FMV number, before you started renting. Ask around for comparable properties. Don’t forget to complete schedule 3 for the rental portion of the condo.
This is not your case, but note that when years of designation = years of ownership, only three numbers are required: dates of acquisition and disposition and proceeds of disposition. The T forms are practically empty, and no capital gains appear anywhere in the return. This is normal! Good luck.
