The Golden Rule: What Makes an Expense Deductible
The Income Tax Act allows a deduction for expenses incurred to earn business income. Three tests decide whether a cost is claimable. If an expense fails any one of them, CRA can disallow it on review.
| Test | What It Means | Example |
|---|---|---|
| Business purpose | The expense must be incurred to earn income, not for personal benefit. | Office rent qualifies. A family vacation does not. |
| Reasonableness | The amount must be reasonable in the circumstances. CRA can reduce amounts that are inflated relative to the business. | A $400 client lunch for a one-person consultancy invites scrutiny. |
| Proper documentation | You must keep a receipt or invoice showing what was bought, from whom, the amount and the date. A bank or credit-card statement alone is not sufficient. | A supplier invoice supports the claim; a line on a Visa statement does not. |
Mixed-use expenses must be apportioned. When a cost serves both business and personal purposes (a vehicle, a home, a cell phone), you may deduct only the business-use portion. The split must be reasonable and supportable. A phone used 70% for business supports a 70% deduction, provided you can show how you arrived at the percentage.
Most of the disputes we resolve on CRA review come down to one of these three tests, almost always documentation or apportionment. The deductions below are all legitimate; the discipline is in claiming the correct portion and keeping the proof. For incorporated owners, accurate deductions also flow directly into the corporate tax return we prepare each year.
2. Vehicle & Motor Expenses (2026 Rates)
Vehicle costs are among the most claimed and most audited business deductions. There are two methods, and the rules differ between an employee or sole proprietor using a personal vehicle and a corporation that owns or leases one.
Method A: Per-Kilometre Allowance (2026 CRA Prescribed Rates)
Used to reimburse an employee or owner-employee tax-free for business driving in a personal vehicle. The reimbursement is non-taxable when it is based solely on business kilometres at or below these rates.
| Travel Region | First 5,000 km | Each km After 5,000 |
|---|---|---|
| Provinces (including Ontario) | 73¢ per km | 67¢ per km |
| Territories (Yukon, NWT, Nunavut) | 77¢ per km | 71¢ per km |
Self-employed owners cannot use the per-kilometre rate as a deduction. The prescribed rate is a reimbursement benchmark for employees. If you are a sole proprietor, your vehicle deduction is built from actual expenses multiplied by your business-use percentage, supported by a logbook. The per-kilometre rate only applies when a corporation reimburses an owner who is also an employee.
Method B: Actual Expenses × Business-Use Percentage
The corporation or sole proprietor deducts the business-use share of real operating costs. The business-use percentage is business kilometres divided by total kilometres for the year, which is why a logbook is essential.
| Deductible Operating Cost | Notes |
|---|---|
| Fuel and oil | Full business-use share. |
| Insurance and licensing | Business-use share of premiums and plate fees. |
| Repairs and maintenance | Business-use share of servicing, tires, parts. |
| Lease payments | Deductible up to the monthly ceiling below. |
| Loan interest | Deductible up to the monthly ceiling below. |
| Capital cost allowance (if owned) | Depreciation, subject to the class ceiling below. |
2026 Passenger Vehicle Cost Ceilings
| Limit | 2026 Amount (before tax) | What It Caps |
|---|---|---|
| Class 10.1 capital cost ceiling | $39,000 | Maximum cost on which CCA can be claimed for a passenger vehicle acquired on or after January 1, 2026. |
| Class 54 (zero-emission) ceiling | $61,000 | Maximum capital cost for an eligible zero-emission passenger vehicle. |
| Maximum deductible lease cost | $1,100 per month | Cap on the monthly lease amount deductible for a passenger vehicle. |
| Maximum deductible loan interest | $350 per month | Cap on monthly interest deductible on a passenger-vehicle loan. |
No logbook, no deduction. The single most common reason CRA reduces a vehicle claim is the absence of a mileage log. Record the date, destination, purpose and kilometres for each business trip. A representative sample period can be acceptable once a full base-year log establishes your pattern, but the base-year log must exist. We help clients set this up correctly so the claim survives review.
3. Home Office Expenses
A business operated from home can deduct the business-use portion of home costs. The portion is usually the area of the workspace divided by the total finished area of the home. If the space is shared, the percentage is reduced for personal hours of use.
| Home Cost | Deductible Share | Notes |
|---|---|---|
| Rent | Business-use % | Often the largest home-office deduction for a tenant. |
| Utilities (heat, hydro, water) | Business-use % | Apportioned on the same square-footage basis. |
| Home insurance | Business-use % | Business portion of the policy. |
| Property tax | Business-use % | Available to owners (not tenants). |
| Mortgage interest | Business-use % | Interest only, never principal. Owners only. |
| Maintenance and minor repairs | Business-use %, or 100% if specific to the workspace | A repair only to the office is fully deductible. |
Be careful claiming CCA on a home you own. Claiming capital cost allowance on the business portion of a residence can jeopardize part of the principal-residence exemption when you sell. For most owners the long-term cost of a partial capital-gains exposure outweighs the modest annual CCA. We generally advise owners to claim the operating costs and skip CCA on the home itself.
The home-office deduction cannot create or increase a business loss. If business income is too low to absorb the full home-office amount in a year, the unused portion carries forward and can be claimed against income from the same business in a future year. Nothing is lost; it is deferred.
4. Meals & Entertainment
Business meals and entertainment are deductible, but generally only at 50% of the amount paid. The 50% limit applies to both the food and beverage cost and any related tax and tip.
| Situation | Deductible Portion |
|---|---|
| Client or business-development meals | 50% |
| Meals while travelling for business | 50% |
| Entertainment (event tickets, sporting events) | 50% |
| Staff events open to all employees (limited number per year) | 100% |
| Meals billed through to a client and itemized on your invoice | 100% |
| Meals provided at the worksite for the employer's benefit (specific cases) | Varies; confirm before claiming |
The all-staff event exception. A holiday party or similar event to which all employees at a location are invited can be fully deductible, subject to CRA's limit on the number of such events per year. Keep the guest list and the purpose with the receipt. Document who attended and why; a receipt with no business context is the weakest position on review.
5. Capital Cost Allowance (CCA) & Asset Classes
Capital assets are not deducted in full in the year of purchase. They are depreciated over time through capital cost allowance, at a prescribed rate per class. The most common classes for a small business are below.
| Class | Typical Assets | CCA Rate |
|---|---|---|
| Class 8 | Furniture, fixtures, equipment, tools over $500, most office equipment | 20% |
| Class 10 | General vehicles, trucks, computer hardware purchased in some periods | 30% |
| Class 10.1 | Passenger vehicles above the cost ceiling (each in its own class) | 30% |
| Class 12 | Tools under the threshold, computer software (non-systems), small items | 100% |
| Class 50 | Computer hardware and systems software | 55% |
| Class 13 | Leasehold improvements | Straight-line over lease term |
| Class 14.1 | Goodwill and intangible assets | 5% |
| Class 54 | Zero-emission passenger vehicles (within the ceiling) | 30% |
The half-year rule and immediate expensing. In most cases only half the normal CCA rate applies in the year an asset is first available for use. Separately, CCPCs have access to enhanced first-year expensing on eligible property, and several accelerated-investment measures allow a larger deduction in year one. Because these incentives change and have annual limits, we calculate the optimal CCA claim asset by asset when we prepare the return rather than defaulting to the maximum.
CCA is optional and you choose how much to claim. You may claim any amount from zero up to the maximum for the class. In a low-income year it often makes sense to claim little or no CCA, preserving the undepreciated balance for a higher-income year. This is one of the most useful planning levers on a small-business return.
6. Payroll, CPP & EI (2026 Limits)
Wages, salaries, bonuses and the employer's share of statutory contributions are fully deductible business expenses. If you employ staff, or pay yourself a salary through your corporation, these 2026 figures govern your source deductions.
| 2026 Payroll Figure | Amount |
|---|---|
| CPP first earnings ceiling (YMPE) | $74,600 |
| CPP basic exemption | $3,500 |
| CPP base contribution rate (employee and employer, each) | 5.95% |
| Maximum CPP base contribution (each, employee and employer) | $4,230.45 |
| CPP2 second earnings ceiling (YAMPE) | $85,000 |
| CPP2 rate on earnings between the ceilings (each) | 4.00% |
| Maximum CPP2 contribution (each) | $416.00 |
| EI maximum insurable earnings | $68,900 |
| EI employee premium rate | 1.63% |
| Maximum EI premium (employee) | $1,123.07 |
| EI employer rate (1.4 × employee) | 2.282% |
Self-employed owners pay both halves of CPP. A sole proprietor remits the employee and employer portions of CPP on net self-employment income, so the effective base rate is 11.90% up to the ceiling, plus CPP2 where applicable. This is settled annually through the personal return rather than through payroll remittances.
Source deductions are the highest-risk remittance in your business. CPP, EI and income tax withheld from employees are held in trust for CRA. Late or missed remittances draw immediate penalties and, in serious cases, director liability. If payroll is part of your business, we strongly recommend a managed payroll service so remittances are never late.
7. Professional, Office & Admin Costs
The day-to-day costs of running the business are generally fully deductible in the year incurred.
| Expense | Deductible | Notes |
|---|---|---|
| Accounting and bookkeeping fees | 100% | Including the fee for preparing the business return. |
| Legal fees (business-related) | 100% | Fees to earn income or for business contracts. Fees to acquire a capital asset are added to the asset's cost instead. |
| Office supplies and stationery | 100% | Consumables used in the business. |
| Software subscriptions | 100% | Accounting, CRM, design and productivity tools used for business. |
| Bank charges and merchant fees | 100% | Business-account fees and payment-processing costs. |
| Telephone and internet | Business-use % | Apportion a shared personal line; a dedicated business line is fully deductible. |
| Salaries to family members | 100% if reasonable | Must reflect actual work at a market rate, with real payment and proper payroll. |
| Rent for business premises | 100% | Commercial rent outside the home. |
Paying a family member must be real. A salary to a spouse or child is deductible only if the person actually performs the work, the rate is what you would pay a stranger for the same work, and the wage is genuinely paid with source deductions handled. Documented, reasonable family wages are a legitimate planning tool; undocumented ones are a frequent audit adjustment.
8. Advertising & Marketing
Marketing costs to promote the business are deductible. For online and media advertising, where you advertise can affect deductibility.
| Marketing Cost | Deductible | Notes |
|---|---|---|
| Online advertising (search, social, display) | 100% | Fully deductible when incurred to earn business income. |
| Website design, hosting and maintenance | 100% | Ongoing costs are deducted; a major build may be capitalized. |
| Business cards, brochures, signage | 100% | Print and physical marketing materials. |
| Sponsorships and promotional items | 100% | Must have a genuine promotional purpose for the business. |
| Advertising in a foreign medium aimed at the Canadian market | Restricted | Advertising directed at Canadians in certain non-Canadian newspapers or broadcasters can be limited or denied. Most digital platform advertising is unaffected, but confirm before large foreign-media buys. |
Keep the invoice and the purpose. Marketing is rarely challenged on principle, but CRA does test that the spend was to earn business income rather than personal. A platform invoice plus a one-line note on the campaign's business purpose is enough to support the claim.
9. Travel & Conventions
Travel undertaken to earn business income is deductible. Meals while travelling remain subject to the 50% limit; other travel costs are generally fully deductible.
| Travel Cost | Deductible |
|---|---|
| Airfare, train, intercity bus | 100% |
| Hotel and lodging | 100% |
| Taxi, rideshare, car rental at destination | 100% |
| Meals while travelling | 50% |
| Conventions (limit of two per year, related to your business) | 100%, within the two-per-year limit |
| Incidental personal days added to a business trip | Not deductible; only the business portion qualifies |
Mixed business and personal travel must be split. When a trip combines business and vacation, only the business portion is deductible. If the primary purpose is personal, the airfare itself may be denied. Keep the agenda, meeting confirmations or conference registration that establishes the business purpose of the trip.
10. Insurance & Interest
| Cost | Deductible | Notes |
|---|---|---|
| Commercial general liability insurance | 100% | Business insurance covering operations and premises. |
| Professional liability / errors & omissions | 100% | Coverage tied to the business's professional activity. |
| Business-property and contents insurance | 100% | On commercial premises or the business-use share at home. |
| Interest on business loans and lines of credit | 100% | Interest on borrowing used for business purposes. |
| Interest on a passenger-vehicle loan | Capped | Limited to the monthly ceiling noted in the vehicle section. |
| Life insurance premiums | Generally not deductible | Narrow exception where a policy is assigned as collateral for a business loan required by the lender. |
Interest follows the use of the money, not the security. What makes interest deductible is that the borrowed funds were used to earn business income. Borrowing against your home to fund the business can still produce deductible interest, provided the use of the funds is properly traced and documented. Keep the paper trail from loan to business use.
11. GST/HST & Input Tax Credits
GST/HST is separate from income tax. Once registered, you charge tax on sales and recover the tax you paid on business purchases through input tax credits (ITCs). ITCs are not an income-tax deduction; they are a credit against the tax you collected.
| GST/HST Point | Rule |
|---|---|
| Registration threshold | Required once worldwide taxable revenue exceeds $30,000 over four consecutive calendar quarters (or in a single quarter). Voluntary registration is available below the threshold. |
| Input tax credits | Recover the GST/HST paid on business purchases and expenses, provided you are registered and hold valid documentation showing the tax. |
| ITC documentation | Receipts must show the supplier's GST/HST number and the tax charged. Missing supplier numbers are a common reason ITCs are denied on review. |
| Meals & entertainment ITCs | The ITC on meals and entertainment is generally restricted to 50%, mirroring the income-tax limit. |
| Quick Method | An optional simplified method for smaller businesses that remits a lower flat rate on sales in exchange for forgoing most ITCs. Worth modelling, it suits some service businesses well. |
Marketplace and platform sellers, read your tax settings carefully. On many marketplaces the platform collects and remits tax on your sales, which changes what you report and what you can claim. If you sell on a marketplace or operate in e-commerce, the interaction between platform-collected tax and your own filing is worth a dedicated review. We handle GST/HST filing as part of our compliance work.
12. Owner Compensation: Salary vs. Dividends
For an incorporated owner, how you pay yourself is a deduction question for the corporation and a tax question for you personally. Neither salary nor dividends is universally better; the right mix depends on your numbers.
| Factor | Salary | Dividends |
|---|---|---|
| Corporate deduction | Deductible to the corporation, reducing corporate tax. | Not deductible; paid from after-tax corporate profits. |
| CPP | Creates CPP contributions (cost now, benefit later). | No CPP contributions. |
| RRSP room | Generates RRSP contribution room. | Does not generate RRSP room. |
| Payroll administration | Requires source deductions and a T4. | Simpler; reported on a T5. |
| Income smoothing | Fixed once declared for the period. | Flexible timing of withdrawals. |
This is a modelling decision, not a rule of thumb. The optimal salary-dividend mix changes with your income level, your need for RRSP room and CPP, whether the corporation needs to retain earnings, and your personal cash needs. We run the numbers for each owner-client every year and recommend the split that minimizes total corporate-plus-personal tax for your situation. Corporate Tax Planning →
13. What You Cannot Deduct
Knowing the disallowed items prevents the adjustments and interest that follow a reassessment. These are the costs CRA routinely denies.
| Not Deductible | Why |
|---|---|
| Personal and living expenses | Not incurred to earn business income. |
| The personal-use portion of any mixed expense | Only the business share is claimable. |
| Clothing for everyday wear | Even if worn to work; only specialized protective or uniform gear qualifies. |
| Federal income tax, penalties and most fines | Income tax itself and statutory penalties are not deductible. |
| Club dues and recreational facility fees | Golf and dining-club memberships are specifically denied. |
| Principal portion of loan or lease payments | Only interest (and CCA on owned assets) is deductible, not principal. |
| The non-deductible half of meals and entertainment | The 50% that the limit removes. |
| Capital purchases (in full, in year one) | Deducted over time through CCA, not all at once, except where immediate expensing applies. |
Drawing money from your corporation is not the same as deducting an expense. Taking funds out as a shareholder draw does not create a deduction and, if not handled correctly through salary, dividends or a properly documented loan, can trigger a shareholder-benefit assessment. This is one of the most common and most expensive errors we correct for new incorporated clients.
14. Records CRA Expects You to Keep
A deduction is only as strong as the record behind it. CRA can ask you to support any claim, and the burden is on you to prove it.
| Record | Requirement |
|---|---|
| Receipts and invoices | Original supplier documents showing item, amount, date and vendor. Statements alone are insufficient. |
| Mileage logbook | Date, destination, purpose and kilometres for business driving. |
| Home-office calculation | The square-footage basis and the supporting utility, rent or property-cost bills. |
| Payroll records | Pay history, remittances, T4/T5 slips and supporting calculations. |
| Bank and credit-card statements | Reconciled to the books; corroborating, not a substitute for receipts. |
| Retention period | Generally six years from the end of the tax year to which the records relate. |
Clean books are the cheapest insurance you can buy. The cost of organized monthly bookkeeping is a fraction of the cost of reconstructing a year under audit pressure, and reconstructed records are always weaker. Our bookkeeping clients walk into any CRA review with every deduction already supported.
