How to Deduct Your Business Mobile Phone Expenses

The Canada Revenue Agency (CRA) lets small business owners, self-employed individuals, and freelancers deduct business-related mobile phone expenses. You can claim up to 100% of your mobile phone bill, but only when you use the device solely for business purposes.

Calculating Your Mobile Phone Bill Tax Deduction

When you use a mobile phone for both personal and business purposes, you must calculate the correct portion of your bill to claim this deduction from the CRA. To do this, you must:

  1. Determine the percentage of the overall bill as data use and phone use.
  2. Review the monthly data and phone call activity to determine the portions you used for business.
  3. Calculate the deduction.

For instance, you have a monthly mobile phone bill of $100, and 60% of the bill stems from data usage, while you pay the other 40% as installments on your device’s original price. Analysis of your bill shows that you use 30% of the data and 80% of the phone for business purposes.

By using these figures, you can calculate the proper deduction by multiplying $100 by your 60% data usage and 30% data usage for business, which comes to $18. You then multiply your $100 payment by the 40% you spend on installment payments and the 80% of phone use for business, which comes to $32. You then add these figures together for a deduction of $50 per month. This calculation looks like: ($100 x 60% x 30%) + ($100 x 40% x 80%) = $50 in tax-deductible mobile phone expenses.

Deducting Your Mobile Phone Bill

Fill out the costs associated with your mobile phone on Form T2125, Statement of Business and Professional Activities, to help determine your business income. When you purchase a new mobile phone, you may deduct that cost over several years as the value of the phone depreciates, or goes down, in subsequent years as the phone gets older.
