T2125 Expense Categories, Explained in Plain English

This is general information, not professional tax advice. For official guidance, see the CRA's business expenses pages or talk to a tax professional.

The T2125 (Statement of Business or Professional Activities) is where self-employed Canadians report business income and expenses with their personal return. It doesn't come with a dictionary, and lines like "capital cost allowance" feel vague when you're staring at a $40 receipt wondering which box it belongs in.

Here are the expense categories freelancers actually use, in plain English.

Advertising and marketing

Costs to promote your business or find clients: online ads, website hosting, business cards, logo design, email marketing tools. A meal with a potential client isn't advertising — that goes under meals and entertainment, below.

Meals and entertainment — the 50% rule

You can generally deduct only 50% of eligible meal and entertainment costs — client dinners, meals during business travel, event tickets with a business purpose. Alcohol falls under the same 50% treatment. Your own everyday lunch at your desk isn't deductible at all. Spent $100 on a client dinner? Keep the full receipt, claim $50.

Office supplies and software

Things you buy to run the business that get used up: paper, ink, postage, and monthly or annual software subscriptions. Durable, lasting items (a $2,000 desk, a laptop) are capital — see capital cost allowance below.

Office rent

Rent for a dedicated workspace outside your home — an office, a co-working desk, a storage unit. If you work from home, skip this line and use business-use-of-home instead.

Vehicle expenses

If you use your vehicle for both business and personal driving, you deduct the business-use portion of your actual costs — gas, insurance, licence and registration, maintenance, and depreciation (CCA). There is no flat per-kilometre rate for self-employed people on the T2125; that per-km rate you've heard of applies to employer allowances, not to your business return.

The evidence the CRA wants is a logbook: date, destination, purpose, and distance for each business trip. After you've kept a full-year logbook once, the CRA accepts a three-month sample logbook in later years as long as your business use stays within about 10% of that base year. Commuting between home and a regular place of work is personal, not business, driving.

Business-use-of-home (the home office deduction)

If you work from home, you can deduct the business share of home costs: rent (or mortgage interest — never principal), property taxes, utilities, home insurance, and maintenance. The business share is calculated on a reasonable basis, usually the area of your workspace divided by the total area of your home.

Two things to know:

• Business-use-of-home expenses can't create or increase a business loss. Anything you can't use this year carries forward to future years.
• Most accountants advise not claiming CCA (depreciation) on your home itself, because doing so can affect the principal residence exemption when you sell. The other home office expenses don't carry that risk.

Phone and internet (business portion)

A dedicated business line is fully deductible. If your phone and internet do double duty, deduct a reasonable business percentage — and be ready to explain how you arrived at it.

Professional fees

Accountants, bookkeepers, and lawyers, for business matters. Fees for preparing the business portion of your tax return count; purely personal legal fees don't.

Capital cost allowance (CCA) — for durable purchases

Equipment that lasts years — computers, cameras, machinery, furniture, vehicles — generally isn't deducted all at once. Instead you depreciate it over time using CCA classes, each with its own rate. The distinction is lasting value: a box of pens is a current expense; a laptop is capital property.

Training and professional development

Courses, conferences, and reference materials that keep you current in your existing field are generally deductible. Training that gives you a lasting new skill or qualification for a different line of work is treated differently (as capital or personal), so tread carefully there.

What you can't claim

• Personal living costs — groceries, clothing, your gym membership.
• Fines and penalties — parking tickets included.
• Mortgage principal — only interest, and only the business-use share.
• Salary to a spouse who doesn't actually work in the business — real work at a reasonable wage is fine; paper arrangements are not.

The habit that makes all of this easy

The biggest mistake is waiting until April to sort a year of receipts and guess at categories from memory. Instead: capture each receipt when you get it, categorize it while you still remember what it was for, and keep everything backed up. The CRA expects you to keep those receipts for six years, so a system you'll actually stick with matters.
