Self-employed Canadians fill out Form T2125 as part of their T1 personal tax return.
The costs that are deductible cover the home office, the vehicle (at a business rate), meals (at 50%), professional fees, advertising, the capital cost allowance on equipment, payments to subcontractors, and other similar items.
Personal expenses, fines, penalties, and subscriptions to clubs are never deductible.
You should retain all your receipts for six years since the CRA has the right to audit any return during that time.
The amount of expenses that are deducted for business purposes is limited by the net business income—these expenses cannot result in a loss.
The Full List of Deductible Self-Employment Expenses
1. Advertising and Marketing (Line 8520)
2. Meals and Entertainment (Line 8523)
The limit set by the CRA for meal and entertainment expenses is 50 per cent of the actual cost.
3. Insurance (Line 8690)
All the types of insurance mentioned—business liability insurance, errors and omissions (E&O) insurance, professional indemnity insurance, commercial property insurance, and business interruption insurance—are payable in full, whereas the premiums for personal life insurance are generally not. Insurance on a vehicle that is used for business should be included in the vehicle expenses section.
4. Interest and Bank Charges (Line 8710)
The interest in business loans, the amounts drawn on business lines of credit, and the balances on business credit cards are deductible. So are the monthly fees charged by your bank, the fees for wire transfers, and the merchant processing fees (if you accept credit cards). However, interest in money borrowed to invest in personal assets is not deductible.
5. Office Expenses (Line 8810)
Things such as paper, pens, toner, stamps, and file folders, together with software subscriptions used in business (like Adobe Creative Cloud, QuickBooks, and project management tools), and small equipment items which are not capitalized, are included. Generally the boundary between 'office expenses' and items that require Capital Cost Allowance (CCA) is about $500: anything that costs more is generally capitalized while cheaper items are expensed right away.
6. Fees of professionals (item 8860)
The costs of accounting for the preparation of your business tax return, the legal fees connected with your business, bookkeeping fees, and business consulting expenses are all deductible. Fees for your personal tax return are not deductible—although the part of those fees that relates to your T2125 generally is. The fee for becoming a member of a professional association that is required for your licence is deductible; however, the cost of a golf club membership is not.
7. Rent (Line 8910)
When you rent an office, a studio, retail space, or a workshop solely for business purposes, the entire rent can be deducted. However, if you work from home, you should not use this provision and instead should use the section on the business use of your home (Part 7 of T2125).
8. Salaries, wages and subcontractor fees (Line 9060 / Line 8860)
The amounts you pay your employees—such as salaries, employer contributions to the CPP, and EI premiums—are deductible. Similarly, payments made to independent subcontractors for services are also fully deductible. However, remember that if you pay a subcontractor more than $500 in a year, you must provide them with a T4A slip and submit the T4A Summary to the CRA by the last day of February in the following year.
9. Telephone and Internet (item 9220)
The business-use portion of your cell phone plan that is used for business purposes, along with home internet and separate business lines, can be deducted. When 65% of your phone use is for business, you should deduct 65% of the monthly bill. To back up your claim regarding the percentage, keep a record of your usage for at least one typical month. A business line that is used exclusively for business purposes is 100% deductible’s 9281–9283)
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.
11. Capital Cost Allowance – CCA (section 9 of T2125)
Assets used in a business which have a long life—such as computers, cameras, machinery and furniture—are not deducted in the year that they are purchased. Instead, you claim CCA each year according to 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 known as the '50% rule') causes your CCA claim to be reduced to half of the normal rate in the year that you get an asset. You are not obliged to claim the full amount of CCA, since claiming less may be advantageous if you want to save your deductions for a year when your income is higher.
12. Business-Use-of-Home (Part 7 of T2125)
So long as your home is your main place of business or if you have a separate area that is used entirely for business purposes, you are allowed to deduct your share of the various home expenses such as rent or mortgage interest (but not the principal), property taxes, utilities (including heat, hydro and water), home insurance, and maintenance. The proportion is generally worked out by dividing the square feet of the area used for business by the total square feet of the home. It should be noted that these expenses cannot result in or increase a business loss; any amount by which a loss exceeds the deductible expenses will be carried forward to the following year.
13. Other Expenses, Line 9270
The general provision on T2125 includes genuine business expenses which are not covered by the categories mentioned above. Examples include professional development courses and books, subscriptions to trade magazines, business-related parking that has not already been claimed in relation to the vehicle, licensing fees, and safety equipment necessary for your job. You should list each item separately together with the amounts.
