Under the “Income” tab, hover over
“Self-Employment” and then select “Business or Professional Activities” from
the sub-menu. This will bring you to the “Your Self-Employment or Business
Summary” page.
Click on “Edit” next to the
business that you want to add the expenses to. On the “[NAME], review your
self-employment income and expenses” page, click on “Business Expenses”. This
will bring you to the “[NAME] let's look at your work expenses” page.
Click the blue “Continue” button
until you reach the “[NAME], did you pay for utilities for a business property?”
page. Here you can enter your telephone expenses. If you are using a mobile phone,
remember to only enter the amount related to your business use. Ex: if you pay
$100 per month for your cell phone service, but use it only 50% for business
use, then you can claim only $50 of your monthly bill as a business expense.
