This should be an area of interest to pretty much anyone that owns a cell phone, so I thought I’d reproduce it here. It’s a recent CRA technical interpretation on the question of whether the cost of a cell phone plan is deductible from employment income.
Deductions from employment income must be specifically provided for under the Income Tax Act. Section 8(1)(i)(iii) deals with supplies used up in the course of performing employment duties. There must be a requirement under the employment contract for the employee to pay for his own supplies, and the employer must sign form T2200 to attest to this requirement.
The CRA was asked whether the cost of a basic cellular service plan is deductible from an employee’s employment income where an employer requires the employee to use a cellular phone to perform employment duties.
CRA Response: It is a question of fact. Section 8(1)(i)(iii) of the Income Tax Act (the “Act”) provides a deduction to an employee for “the cost of supplies that were consumed directly in the performance of the duties of . . . employment and that the . . . employee was required by the contract of employment to supply and pay for.” For supplies to be considered consumed directly in the performance of employment duties, the supplies must be used up and play an integral and essential part in the performance of the employment duties. The cost of the supplies should also be reasonable.
Based on the above, cellular minutes and data would be considered “supplies that were consumed directly” where it is determined that the cellular minutes and data were used up and played an integral and essential part in the performance of the employment duties. It is our understanding that service providers typically provide a detailed breakdown of each cellular minute used, but do not similarly provide a detailed breakdown of cellular data used. It is our view that without a detailed breakdown an employee would not be able to substantiate the amount of cellular data that was used for employment purposes. Where the cellular minutes or data and costs cannot be substantiated, a deduction from employment income is not permitted under s. 8(1)(i)(iii) of the Act. If an employee can substantiate that they used their cellular phone exclusively for employment purposes (i.e., no personal use), it is our view that the basic service plan may reasonably reflect the cost of those cellular minutes and data. Where there is both employment and personal use and the employment use can be substantiated, an employee may apportion the basic service plan on a reasonable basis. However, if only the employment use of cellular minutes can be substantiated, only the portion of the basic service plan for minutes may be apportioned (i.e., the portion of the basic service plan for data cannot be deducted).
