Are you missing out on tax deductions for your small business? If you're self-employed and you're not sure what qualifies as a business expense in the eyes of the Canada Revenue Agency (CRA), you could be leaving hundreds or even thousands of dollars unclaimed at tax time!
It's not just about knowing what expenses the CRA will accept as a write-off. You also have to keep detailed records to back those claims. Many sole proprietors don't have a system in place to capture everything they spend throughout the year, lost receipts or poor expense documentation can mean missing out on what could be potentially significant tax savings for some businesses.
Every dollar you spend running your business has potential value at tax time. The CRA recognizes that sole proprietors need home offices, reliable vehicles, and other essentials to operate. If you claim these costs properly, you can lower your taxable income, which in turn will help you keep more of your hard-earned money.
You might be surprised what you can claim as someone who's self-employed.
Home office expenses: Working from home means you can claim a percentage of your rent (or mortgage interest), utilities, insurance, and maintenance costs, based on how much square footage your workspace occupies.
Vehicle and transportation costs: Business mileage adds up fast. Keep records of every work-related trip to claim your share of fuel, insurance, maintenance, and lease expenses. Transit passes, parking fees, and rideshares for your business also qualify as Canadian small business tax write-offs.
Professional development: Any courses, certifications, or conferences that improve your skills related to your business are deductible. These expenses can often be overlooked because owners view them as personal expenses.
Technology and supplies: Office supplies, including computers, software subscriptions, and furniture, all count. Physical items over $200 are typically claimed as a capital cost allowance (property that loses value over time, such as computers, equipment, or furniture), with the expense spread over several years. Also worth noting: the 2025 federal budget proposed several tax incentives, collectively referred to as the “Productivity Super-Deduction,” that will allow businesses to write off a larger share of their capital investments sooner.
Professional services: **Accounting, legal, and bookkeeping fees and bank charges are all small-business tax deductions. You can also claim tax-preparation software such as TurboTax as a business expense.**
Marketing and advertising: Website costs, business cards, social media ads, and promotional materials qualify as Canadian small-business tax write-offs.
Insurance premiums: Liability insurance and portions of health insurance may be deductible, depending on the structure of your business.
Meals and entertainment: You can deduct 50% of reasonable meal and entertainment expenses when they're directly related to earning business income. The key is proper documentation: keep receipts and take note of who you met with and the purpose of the meeting.
