Are cell phones fully deductible?
My client is using 2 cell phone and I am not sure if they are both fully deductible. Is there a rule on this?
If using only one cell phone, is that fully deductible?

Hi Kaila,
CRA's postion on cellular phone use is found at https://www.canada.ca/en/revenue-agency/services/tax/businesses/topics/payroll/benefits-allowances/provided/cellular-phone-internet-services.html .
I discuss briefly land line phones at
T2125 Line 9220 and also when discussing
what expenses are not deductible.
The key to deductibily when you are a business owner is
incurring the expense to earn income.
You might want to take at look at the CRA publication
Excise and GST/HST News No. 61 from the summer of 2006 -
Ordinary location of mobile phones.
It discusses that there "are special rules for determining whether a particular call is subject to GST/HST in the situation where a cellular service provider charges a subscriber for calls made on his or her cell phone on a pay-per-use basis."
The CRA publication
T4130 Employer's Guide Taxable Benefits and Allowances discusses cellular phone service.
The Canadian Tax Resource published an article in March 2010 on
Deductions From Employment Income. Salesperson expenses were discussed.
Under
expenes permitted as salesperson expenses, it says, "Supplies used directly in your work. This includes office supplies, cellular phone airtime, and long distance (your normal monthly charge for cellular or telephone cannot be deducted)."
Jones & O'Connell posted an excellent article in September 2016 entitled
Employer-provided cell phones - the potential tax cost.
Updated March 2017 - be sure to read this articleWhile these references / articles are discussing employees, some of the logic could be applied to the sole proprietor when trying to determine "What is a reasonable expense?"
So, are two cell phones deductible?
I think it would be pretty tough to explain why the business owner needs 2 business cell phones for himself. He can only use one at a time. Any individually charged calls would certainly be deductible if they were related to business and were not personal in nature.
Is one cell phone fully deductible?
Again it depends. Is it used 100% for business with no personal useage? Is the plan a basic one? Does the owner's personal use of the cell phone result in charges over the basic plan?
You can always phone CRA and ask their opinion.
