One of the common reasons for the employment expenses not to be calculated properly is due the box 12. Box 12 has to be filled and the CRA calculator must be used to get the proper amount to enter.

Home office expenses for employees. How to claim 

Thank you for using TurboTax.

Thank for the suggestion. However, line 12 makes no difference, whether I put the correct number, or $20, or $20000, the results are the same. The only box on that form that actually changes how much is being calculated for my final employment expenses is Line 1.

II face same issue. Have you been able to find a solution

My solution was to use a different free tax software that works 🙂

Hi, just wondering if you were ever able to figure out how this got calculated. I just discovered a similar issues with my 2021 return but unfortunately it’s because CRA is asking for documentation. I told the software we did not have expenses but yet it somehow calculated that we had $20k. 

If you see a calculation issue, please contact our phone support at 1-888-829-8608 as they can view your return to see what the issue might be.
