Business Expenses

Business expenses are any expenses you incur to keep your business or self-employed practice operational and to earn income. In Canada, there are two main types of business expenses - current and capital.

Generally, current expenses can be deducted in full (so long as they are eligible) in the year the expenses are incurred. Capital business expenses, on the other hand, can be claimed over a few years.

The CRA strictly defines what business costs are deductible, and in most categories, you may have current and capital expenses.

Business expenses you can claim

The CRA allows for many different business expenses to be deducted. The most common deductible expenses can be both fixed and variable expenses. Some of these include:

  • Rent, utilities, accounting, administration and legal fees
  • Interest and bank fees
  • Property taxes
  • Wages, bonuses and commissions
  • Eligible employee expenses you have reimbursed
  • Maintenance and repairs
  • Vehicle expenses
  • Business travel
  • Office supplies
  • Advertising
  • Allowable meal and entertainment expenses
  • Home as a business place if it is the principal place of your business

Capital expenses include other business costs that are “bigger” and provide a lasting benefit to your business or practice - they do not run out or need to be replaced or replenished quickly. These can include purchasing capital property (note you can only deduct GST/HST minus the amount of any claimed input tax credit), vehicles, office furniture, maintenance and repair on business assets of a lasting nature or improvement, replacing assets and more. 

We recommend consulting with a tax professional to find out more about capital business expenses.

Keep track of your business expenses

You are obliged to substantiate your business expenses claim you want to deduct at tax time. The CRA states that you must keep receipts of all eligible business expenses to prove them. The receipts of your business expenses must clearly show the following information:

  • The date of the purchase/transaction
  • The name of address of the seller and buyer
  • A full description of the purchased goods or services
  • The business number of the vendor, if they are GST/HST registrant

In the event that the seller did not provide you with a receipt or invoice, the CRA allows that you write down the name and address of the seller, how much you have paid for the purchased goods or services, the date and details of the transaction in your business’ expense journal.

In order to keep track of your vehicle mileage to calculate car expenses, we recommend using an automatic mileage tracker, or if you prefer a manual way - a CRA mileage log template. See the mileage log requirements in Canada.


If a designated workspace in your home is the principal place of your business, or you use it solely to earn business income on an ongoing basis, you will be able to claim expenses such as home insurance, electricity, heating and cleaning supplies. You will also be able to deduct a portion of your property taxes, mortgage interest and CCA. Calculate the business use of home expenses based on the area you use for your workspace divided by the total area of your home. The percentage you work out will be the percentage of the aforementioned expenses you can claim.
In order to write off business expenses, they will need to be for the purpose of earning income and operating your business. You must keep receipts of all business expenses throughout the year as proof. Claim business expenses at your tax return each year to lower your taxable profit.
You can use a filing system for your business expense receipts, or an expense journal in instances where you weren’t provided with a receipt. Make sure to keep receipts organized, so you aren’t missing any. Consider using tax software or an application with which you can scan receipts right away to keep them safely stored.
