I have the same issue as well where line 12 of T777S in Ufile for Detailed method shows different value from the CRA calculation.
How do I enter expenses paid for the work space only in Ufile so that the amount can go on line 12 of the T777S form?
Here is the summary generated by the CRA calculation which shows $538.21 on line 12. However, Ufile shows $468.17 instead of sum of $468.17 and $70.04.
Summary of the employment-use amount
$538.21 is the employment-use portion.
This amount will go on line 12 of the T777S form.
The total amount of the employment-use portion is based on:
$468.17 expenses paid for the entire home and work space
$2,564.27 × 18.26%
$70.04 expenses paid for the work space only
$70.04 × 100%
