What the CRA Actually Allows as a Business Expense in Canada

There are only two tests, and everything else follows from them.

Was it incurred to earn business income? and was the amount reasonable in the circumstances? Meet both and the expense is deductible. Fail either and it is not, no matter how the receipt is labelled.

Most disputes are not about whether an expense qualifies in principle. They are about whether the taxpayer can show it did.

The full-deduction list

Ordinary operating costs, deducted in the year:

• Advertising and marketing
• Bank charges and merchant fees
• Insurance on business property
• Interest on business borrowing
• Legal, accounting and consulting fees
• Licences, dues and subscriptions used in the business
• Office supplies
• Rent
• Repairs and maintenance
• Salaries, wages and benefits
• Telephone and internet, business portion
• Travel, business portion

The partial ones, which is where people go wrong

The 50% meals rule catches almost everyone. Taking a client to lunch is deductible at half. Buying your own lunch while working is not deductible at all, because you would have eaten regardless. The exception is meals while travelling overnight on business, which are still limited to 50% but are at least eligible.

Three carve-outs from the 50% limit are worth knowing, because they are the ones people qualify for without realising:

• You billed the cost to the client and showed it on the invoice. The limit moves to whoever bore it, so a recharged meal is fully deductible to you
• Staff events. An event to which you invite all employees at a location is not restricted, up to six such events a year
• You are in the business of providing food, beverages or entertainment for compensation, which is why a restaurant does not halve its own food cost

The same halving flows through to sales tax. The CRA’s guidance on input tax credits allows an ITC on meals and entertainment for the allowable part only, so a registrant claiming the full GST/HST on a client dinner has overclaimed twice over. Club dues get no ITC at all, matching the income tax denial. The wider rules are in GST/HST input tax credits.

Vehicle claims live or die on a logbook, which is covered in vehicle expense deductions.

Never deductible

• Personal and living expenses
• Clothing, unless it is a genuine uniform or protective gear. A suit you wear to client meetings is not deductible, however necessary it feels
• Fines and penalties, including parking tickets and CRA interest
• The cost of an asset itself, which goes through capital cost allowance instead
• Political contributions
• Life insurance premiums, in most circumstances
• Club membership dues where the main purpose is dining, recreation or sport
• Expenses you were reimbursed for

CRA interest and penalties being non-deductible is worth internalising. It means the effective cost of paying late is higher than the headline rate, which is a point made in corporate tax deadlines.

The reasonableness test has teeth

An expense that is genuinely business-related can still be reduced if the amount is unreasonable. A $600 dinner for two, a vehicle far beyond what the business requires, a salary to a family member well above market for the work performed.

Family salaries are the most common version. Paying your spouse a wage is entirely legitimate if they do the work and the pay reflects it. Keep a record of what they did and what comparable work costs. Paying a teenager $40,000 to update a website will not survive a question.

Paying is not the same as deducting

Two timing rules quietly move deductions between years.

Prepaid expenses. Under the accrual method you deduct the portion of a prepayment that relates to the year, not the cheque. Twelve months of insurance paid in October gives you three months of deduction this year and nine next. Financing fees on a business loan go further still: application, appraisal, processing, insurance, guarantee, brokerage and related legal fees are generally deducted at 20% a year over five years, whatever the term of the loan, with the balance released if you repay early.

Non-compliant short-term rentals. Where short-term rental income is earned in breach of the provincial or municipal registration and licensing rules that apply to it, the CRA denies the non-compliant portion of the expenses, including CCA. The income stays taxable and the deductions do not. If you rent a property short-term, the licence is now a tax document, a point that runs through rental property accounting.

Startup costs, before there is a business

You may generally deduct expenses incurred before your first sale, provided the business had genuinely commenced. The line is between preparing to carry on a business and investigating whether to start one. Costs of the former are deductible; costs of the latter are usually not.

Keep those receipts from the start. People routinely discard them because the business “was not running yet”.

The documentation that makes it survive

The CRA’s position is unambiguous: a bank or credit card statement shows money moved, not what it was for. You need the invoice or receipt.

For anything a stranger would not immediately recognise as a business cost, add a note at the time: who, what, why. A one-line note written in the moment is worth more than any explanation constructed two years later.

Keep records for six years from the end of the tax year they relate to.

Three habits do most of the work:

1. Separate business and personal banking. Every commingled transaction is a decision to make and defend later.
2. Photograph receipts on the spot and attach them to the transaction.
3. Reconcile monthly, so a missing receipt is found in week four rather than month fourteen. The routine is in the monthly close.

Claim what you incurred, keep the paper that proves it

Claiming aggressively with no records is how people lose deductions. Claiming conservatively out of vagueness is how they overpay.

The middle position is the correct one: claim everything genuinely incurred to earn income, at a reasonable amount, and keep the paper that proves it. That position holds up.

If you suspect you are leaving legitimate deductions unclaimed, or claiming things that will not survive a look, a review of one year’s expenses usually pays for itself.
