T777 - Line 229 - How do I enter Cell Phone expenses? Specifically, do I enter the amount before tax, or the tax total under the HST Taxable box?
I have to claim 40% of my cell phone as an employment expense. I know how to get to "Other Employment Expense" page but it is broken out into GST Taxable, HST Taxable and Zero rated & exempt. That being said, I am from Ontario so I will enter it under the HST Taxable column but I'm not sure what number to enter in that box. Do I calculate what I think is an appropriate percentage of use for employment use was? I think it is fair to say 40% was used for work.
Do I total 40% of my cell phone bill for the year without tax and enter that number in the box? Or, do I total 40% of my cell phone bill for year and enter the amount of tax I paid in that box? Or, do I enter the 40% of my total cell phone bill for the year including tax?
