- Self-employed Canadians report income and deductions on Form T2125, filed as part of their T1 personal return.
- Deductible expenses include home office, vehicle (business %), meals (50%), professional fees, advertising, CCA on equipment, subcontractors, and more.
- Personal expenses, fines, penalties, and club memberships are not deductible — ever.
- Keep all receipts for six years; the CRA can audit any return within that window.
- Business-use-of-home expenses are capped at net business income — they cannot create a loss.
What Is Form T2125 and Who Files It?
Form T2125 — the Statement of Business or Professional Activities — is the CRA's vehicle for reporting self-employment income and expenses. It is not a separate filing; it attaches to your T1 personal income tax return. You need one T2125 for each distinct business or professional activity you carry on.
If you received a T4A slip with amounts in Box 020 (self-employment commissions) or Box 048 (fees for services), you almost certainly need to file T2125. The same applies if you earned income as a freelancer, consultant, contractor, Uber driver, Etsy seller, or any other self-directed business activity — with or without a T4A.
The form collects your gross business income, all allowable expenses, and calculates net income (or loss). That net figure flows to line 13500 (business income) or line 13700 (professional income) of your T1, where it gets added to your total income and taxed at your marginal rate after applying any other deductions.
The Full List of Deductible Self-Employment Expenses
The following categories are explicitly recognized by the CRA on T2125. For each, you may only deduct the portion that is reasonable and incurred to earn business income.
1. Advertising and Marketing (Line 8520)
Online ads (Google, Meta, LinkedIn), business cards, flyers, website hosting costs, sponsored posts, and any other promotional spending are fully deductible. There is no percentage limit here — 100% of legitimate advertising costs qualify. Your website domain registration and content creation costs for marketing also fall here.
2. Meals and Entertainment (Line 8523)
The CRA limits meal and entertainment deductions to 50% of the actual cost. If you take a client to dinner and the bill is $200, you can deduct $100. The expense must be for business purposes — a client meeting, a business conference lunch, or entertaining a prospect. Your own everyday meals while working are not deductible (with limited exceptions for travel away from your tax home).
3. Insurance (Line 8690)
Business liability insurance, errors and omissions (E&O) insurance, professional indemnity insurance, commercial property insurance, and business interruption insurance are all deductible in full. Personal life insurance premiums generally are not. Vehicle insurance attributable to business use belongs in the vehicle expense section.
4. Interest and Bank Charges (Line 8710)
Interest paid on business loans, lines of credit used for business, and business credit card balances is deductible. Monthly bank account fees, wire transfer fees, and merchant processing fees (if you accept credit cards) also qualify. Interest on money borrowed to invest in personal assets does not.
5. Office Expenses (Line 8810)
Office supplies — paper, pens, toner, stamps, file folders — plus software subscriptions used for business (Adobe Creative Cloud, QuickBooks, project management tools), and small equipment items that are not capitalized. The line between "office expenses" and items requiring Capital Cost Allowance (CCA) is generally around $500: items costing more are usually capitalized; cheaper items are expensed immediately.
6. Professional Fees (Line 8860)
Accountant fees for preparing your business tax return, legal fees related to your business, bookkeeping fees, and business consulting costs all qualify. Fees for your personal tax return are not deductible — but the portion attributable to your T2125 generally is. Joining a professional association required for your licence is deductible; a golf club membership is not.
7. Rent (Line 8910)
If you rent an office, studio, retail space, or workshop exclusively for business, the full rent is deductible. If you work from home, do not use this line — use the Business-Use-of-Home section (Part 7 of T2125) instead.
8. Salaries, Wages, and Subcontractor Fees (Line 9060 / Line 8860)
Amounts you pay to employees (salaries, CPP employer contributions, EI premiums) are deductible. Payments to arm's-length subcontractors for services are also fully deductible. Remember: if you paid a subcontractor more than $500 in the year, you must issue them a T4A slip and file a T4A Summary with the CRA by the last day of February of the following year.
9. Telephone and Internet (Line 9220)
The business-use portion of your cell phone plan, home internet, and dedicated business lines is deductible. If 65% of your phone usage is for business, deduct 65% of the monthly bill. Keep a usage log for at least a representative month to support your percentage claim. A dedicated business-only line is 100% deductible.
10. Vehicle Expenses (Lines 9281–9283)
Gas, insurance, repairs, maintenance, parking, registration, and the CCA on a business vehicle are all deductible — but only in proportion to business use. If you drove 25,000 km during the year and 15,000 km was for business, your business-use percentage is 60%. You must maintain a mileage logbook to claim vehicle expenses. (See our dedicated article on vehicle expense rules for the 2025 prescribed limits.)
11. Capital Cost Allowance — CCA (Part 9 of T2125)
Long-lived business assets — computers, cameras, machinery, furniture — are not expensed in the year of purchase. Instead, you claim CCA each year based on the asset class:
| Asset Type | CCA Class | Rate |
|---|---|---|
| Computers & tablets | Class 50 | 55% |
| Passenger vehicles (over $38,000) | Class 10.1 | 30% |
| Other vehicles & equipment | Class 10 | 30% |
| Furniture & fixtures | Class 8 | 20% |
| Buildings (non-residential) | Class 1 | 4% |
| Software (not Class 12) | Class 12 | 100% |
| Zero-emission vehicles | Class 54 | 30% |
The half-year rule (also called the "50% rule") reduces your CCA claim to half the normal rate in the year you acquire an asset. You are never required to claim the maximum CCA — claiming less can be useful if you want to preserve deductions for a higher-income year.
12. Business-Use-of-Home (Part 7 of T2125)
If your home is your principal place of business, or you have a dedicated space used exclusively for business, you can deduct a proportionate share of home expenses: rent or mortgage interest (not principal), property taxes, utilities (heat, hydro, water), home insurance, and maintenance. The proration is typically calculated as business-area square footage divided by total home square footage. These expenses cannot create or increase a business loss — any excess carries forward to the next year.
13. Other Expenses — Line 9270
This catch-all line on T2125 accommodates legitimate business expenses not covered by the named categories above. Common examples include: professional development courses and books, trade magazine subscriptions, business-related parking not already claimed under vehicle, licensing fees, and safety equipment required for your work. List each item separately with amounts.
What Does NOT Qualify as a Deduction
- Personal expenses — groceries, personal clothing, personal vacations, and your regular commute to a fixed workplace.
- Fines and penalties — parking tickets, CRA interest and penalties, speeding fines, and regulatory penalties.
- Club memberships — golf clubs, social clubs, and recreational facility memberships are specifically excluded by the Income Tax Act.
- Personal life insurance premiums — not deductible for sole proprietors (though some group plans may qualify).
- Capital expenditures expensed directly — if an item lasts more than one year and costs more than about $500, it is generally a capital expense requiring CCA, not an immediate deduction.
- Charitable donations — these go on Schedule 9 of your T1 as personal credits, not as business expenses.
- Income tax payments — your personal or instalment tax payments are not business expenses.
Record-Keeping Requirements
The CRA requires you to retain all documents supporting your claimed deductions for six years from the end of the tax year to which they relate. This means your 2025 records (filed in spring 2026) must be kept until at least the end of 2031.
Acceptable records include: original paper receipts, digital scans or photographs of receipts (stored in a readable format), bank statements, credit card statements (as supplementary evidence), contracts, invoices issued to clients, and any written agreements for subcontractor services. The CRA has confirmed that electronic records are acceptable as long as they are accurate and complete.
For vehicle expenses, your logbook is particularly critical. It must record the date, destination, purpose, and kilometres for each business trip. A logbook maintained for a complete 12-month base year can be used with an annual "sample period" logbook for subsequent years — but only if your business use remains relatively consistent.
Common Mistakes Self-Employed Canadians Make
Even experienced self-employed people make errors on T2125. Here are the most frequent ones:
- Mixing personal and business expenses. Deducting 100% of a phone or internet bill when personal use is significant is a common audit trigger. Estimate your business percentage honestly.
- Forgetting the 50% meals limit. Many people deduct 100% of meals. The limit is strict — 50% always applies.
- Not claiming CCA. Some people forget they can depreciate their laptop, camera, or equipment. CCA can be a meaningful deduction, especially in the first year of ownership.
- Claiming mortgage principal as a home-office expense. Only mortgage interest (not the principal repayment portion) can be included in home-office calculations.
- Missing the T4A issuance deadline. If you paid subcontractors, T4A slips must be issued by the last day of February following the tax year.
- Reporting gross income without claiming all eligible expenses. Some people report only net deposits to their bank account as income, rather than tracking all income and all expenses separately.
Practical Example: Freelance Designer in Ontario
To illustrate how these deductions work together, consider a freelance graphic designer in Ontario with $85,000 in gross revenue for 2025:
| Expense Category | Total Cost | Business % | Deductible Amount |
|---|---|---|---|
| Software subscriptions | $2,400 | 100% | $2,400 |
| Advertising (Google Ads, portfolio site) | $3,600 | 100% | $3,600 |
| Professional liability insurance | $1,200 | 100% | $1,200 |
| Phone bill | $1,800 | 70% | $1,260 |
| Home internet | $1,200 | 60% | $720 |
| Client meals (50%) | $1,600 | 50% | $800 |
| Professional development | $1,500 | 100% | $1,500 |
| Accountant fees | $900 | 100% | $900 |
| Home office (20% of home) | $18,000 home costs | 20% | $3,600 |
| CCA on computer ($2,800 cost) | $2,800 | Class 50, 55% | $770 (half-year) |
| Total Deductions | $16,750 |
Net business income: $85,000 - $16,750 = $68,250. At Ontario marginal rates around 43.41% on income in that bracket, these deductions save approximately $7,275 in combined federal and provincial tax compared to not claiming them.

Frequently Asked Questions
Can I deduct 100% of my meals when self-employed?
No. The CRA limits meal and entertainment deductions to 50% of the actual cost, and only when the expense is for business purposes — such as a client dinner or a business meeting over lunch. Personal meals are not deductible.
What is Form T2125 and who needs to file it?
Form T2125, Statement of Business or Professional Activities, is filed as part of your T1 personal tax return. Any individual who earns self-employment income — including freelancers, consultants, gig workers, and sole proprietors — must complete T2125 to report gross income, allowable expenses, and net business income.
Can I deduct my home internet bill?
Yes, but only the business-use portion. If you use your home internet 60% for business and 40% personally, you can deduct 60% of the bill on T2125. You must keep records supporting the business-use percentage you claim.
Are fines and penalties deductible business expenses?
No. The Income Tax Act specifically prohibits deducting fines, penalties, or amounts paid to settle lawsuits arising from illegal acts. This includes parking tickets, CRA penalties, and regulatory fines.
What does Line 9270 cover on T2125?
Line 9270 is the "Other expenses" catch-all line. It covers legitimate business expenses that don't fit neatly into the pre-printed categories — things like professional development, bank charges, licence fees, or specialized industry costs. List each item separately and be prepared to justify each one if the CRA asks.
