Do you know what tax deductions your business is eligible for?

When tax season comes around, it’s important to make the most out of eligible deductions to save you money and help your business grow!

However, before you start claiming whatever you can for your business, be sure that all deductions are supported by original invoices and paperwork.

Doing so is the best way to avoid an audit or any issues if you are audited.

Eligible Expenses to Claim

As a general rule, businesses can claim expenses that maintain the business and ensure that it is operational.

And there is a lot you can claim! To maximize your business tax return, be sure to take advantage of these tax-deductible business expenses:


You can deduct costs for advertising on Canadian radio and television, in Canadian newspapers, and digital advertising.

Bad Debts

If you have already included an accounts receivable as income during the year, you can claim it as a bad debt if it won’t be paid.

Business Start-Up Costs

Tax-deductible business expenses include those that preceded the operation of your business as long as you operated your business in the fiscal period in which the expense was incurred.

Business and Property Taxes

Be sure to deduct any business taxes incurred while running your business as well as property taxes for the building and land where your business is located.

Business Fees and Licenses

Fees, licenses, and dues related to your business are deductible unless the main purpose of the fees is dining, recreation, and entertainment.


If you run your business from your home, you can claim use-of-home expenses such as heat, electricity, insurance, maintenance, and other expenses.

However, you can only claim a percentage that is dependent on the size of your office compared to the rest of your home.

Capital Costs and Allowance

When you acquire a depreciable property (such as equipment, a motor vehicle, a building, etc.), you cannot deduct the cost of the property because its value decreases over time.

Instead, you can deduct the cost over a period of several years


If your business is involved in delivery, freight, and express, you can claim certain expenses on your taxes.

You can deduct the cost of labor and materials when it comes to minor repairs or maintenance done to your business property.

Meals and Entertainment

This business tax deduction applies to meals and entertainment during business-related travel or events. It also applies to long-haul truck drivers who can deduct 80% of their food costs.

Motor Vehicle Expenses

If your business utilizes a motor vehicle to earn income, you can deduct related expenses.

Office Expenses and Supplies

When you run a business, you can claim the costs of office supplies such as pens, paper, and any supplies required to provide your goods and services.

Office expenses do not include capital expenditures.

Prepaid Expenses

Under the accrual method of accounting, you can claim expenses you paid ahead of time such as warranty, contracts, taxes, and workers’ compensation liability.


If you rent your business property, you can deduct rent for the land and building.

However, if you are claiming rent as a home business expense sense, this is done under business-use-of-home.

Salaries and Benefits

As a business with employees, you can deduct gross salaries and other benefits such as CPP (Canada Pension plan) and EI (Employment Insurance) premiums.


Tax-deductible business expenses for utilities include telephone, gas, oil, electricity, water, and internet – as long as you incurred the expense to earn an income.

Ineligible Expenses You Cannot Claim

While there are many tax-deductible business expenses, there are some that you cannot claim on your business taxes:

  • Clothing purchases including special gear
  • Reimbursed maintenance and repair costs
  • Political contributions
  • Governmental penalties and fines
  • Personal purchases

Recent Changes to Deductions (If applicable)

One recent change made by the CRA in 2017 eliminates the ability to claim allowance on eligible capital property.

Property that would have been considered eligible capital property is now considered to be depreciable property and can be claimed under “capital cost allowance.”


How do I claim items and services that I use for both home and work, like my cell phone or vehicle?

You will have to figure out the portion that is used for business, create a percentage using the total use, and deduct that from your business taxes.

For example, if you use your cell phone for 25 hours per week for business and 90 hours total for the household, this would equal 27% so you would deduct that percentage of your cell phone bill.

Depreciable equipment, such as laptops, is considered capital costs. You can deduct the value of the equipment over a number of years – this is known as a capital cost allowance (CCA).
