How to categorize business expenses (with examples)
Categorizing expenses well is what turns a pile of transactions into books you can actually use — and into a tax return that captures every deduction you're owed. Miscategorize, and you either overpay tax or invite questions. Here's how to do it cleanly.
Why it matters: categories drive your financial statements and your tax return. Good categorization means accurate reports, every legitimate deduction claimed, and a year-end hand-off instead of a cleanup project.
Common business expense categories
- Cost of goods sold — materials, inventory and direct costs of what you sell.
- Rent & occupancy — office, shop or storage rent, and related costs.
- Wages & subcontractors — employee pay (and its own payroll accounts) and amounts paid to contractors.
- Software & subscriptions — the tools you run the business on.
- Advertising & marketing — ads, website, design, promotion.
- Vehicle & travel — business mileage, fuel, and travel costs (with the personal-use portion excluded).
- Meals & entertainment — often only partly deductible, so keep it in its own category.
- Office supplies — consumables used in the business.
- Professional fees — accounting, legal, consulting.
- Bank & processing fees — account charges and payment-processor fees.
- Insurance — business coverage.
- Utilities & telecom — power, internet, phone.
The rules that keep it clean
Separate business from personal
The single most important habit: a dedicated business bank account and card. Mixing personal and business spending is the fastest way to miscategorized books and a painful year-end.
Watch the tricky ones
- Meals & entertainment are frequently only 50% deductible — keep them separate so the limit is easy to apply.
- Equipment vs. supplies: a laptop or tool that lasts years is usually a capital asset (depreciated), not an expense. Small consumables are supplies.
- Owner draws are not an expense. Money you take out is equity, not a deductible cost — category it accordingly.
- Vehicle use needs the business portion separated from personal, ideally with a mileage log.
Be consistent
Put the same kind of expense in the same category every time. Consistency is what makes month-over-month comparisons meaningful and reports trustworthy.
Keep the receipt with the transaction. The CRA can ask you to support any expense. Filing the receipt or PDF against each entry as you go turns an audit request into a quick export instead of a scramble.

Frequently asked questions
How should I categorize business expenses?
Sort each cost into a consistent, meaningful category — cost of goods sold, rent, wages, software, advertising, vehicle, professional fees and so on — keeping business separate from personal and filing a receipt with every entry. Consistency and a dedicated business account are what keep it accurate.
Are business meals fully deductible?
Often not — business meals and entertainment are frequently only 50% deductible. Keeping them in their own category makes the limit easy to apply correctly at tax time. Confirm the current rules with your accountant.
Is buying equipment an expense?
Usually not a full expense in the year of purchase. Equipment that lasts multiple years is typically a capital asset, recorded as an asset and depreciated over time, while small consumables are recorded as supplies expense.
