For small business owners, the line between a taxable benefit and a simple expense reimbursement isn’t always as clear as it seems.
You cover your employee’s phone bill, pay out a mileage claim, or hand out a bonus, but how do you know which one goes on the T4 and which one doesn’t?
Understanding taxable benefits vs reimbursements is more than just a bookkeeping detail. It’s something the CRA pays close attention to, and if the reporting isn’t accurate, you could face penalties, reassessments, or even an audit.
In this post, I’ll walk you through the difference between the two, give you examples of each, and explain the CRA audit red flags for expense reimbursements at tax time.
What Are Taxable Benefits?
A taxable benefit is any perk, payment, or advantage you provide to an employee that has a personal value to them. If the employee gains personally, whether in cash or through a company-paid item, the CRA likely considers it a benefit that should be reported as taxable income.
These benefits need to be included on the employee’s T4 and are often subject to payroll deductions like CPP and EI.

What Are Expense Reimbursements?
On the other hand, expense reimbursements are repayments you make to employees for out-of-pocket business expenses. These are things they paid for on the company’s behalf, not perks for personal use.
When handled properly, reimbursements are non-taxable and don’t need to appear on the T4.
But here’s the catch. If a reimbursement crosses into personal use territory or lacks proper documentation, the CRA may reclassify it as a taxable benefit. That’s where problems start.
Examples of Taxable Benefits
Let’s look at a few common taxable benefits we see business owners provide, sometimes without realizing they need to be reported:
- Personal use of a company vehicle
- Cell phone plans where the employee also uses the phone for personal reasons
- Cash bonuses or performance incentives
- Gift cards, unless they fall under CRA’s gift policy
- Employer-paid memberships such as gyms, clubs, or professional associations used personally
All of these provide personal value to the employee, which is why they’re considered taxable. These should be reported on the T4, typically in Box 14 (employment income) and Box 40 (other taxable benefits).

Examples of Non-Taxable Reimbursements
Now let’s talk about the other side. Legitimate business reimbursements that should not be taxed or reported on the T4, assuming they’re properly documented.
- Mileage for business travel, paid at the CRA’s prescribed rate
- Office supplies purchased by the employee and used exclusively for work
- Meals or accommodations while travelling for business
- Internet costs for employees working remotely (when supported by a policy)
A common question I get is, is mileage reimbursement taxable income in Canada? The answer is no, as long as it’s paid at or below the CRA’s standard rate and the travel was business-related.
The key here is documentation. Receipts, logs, or travel details show the CRA that it was a real business cost, not a hidden benefit.
How to Handle Reimbursements on a T4
If a reimbursement is legitimate and non-taxable, it should not appear on the T4. Instead, it should be tracked through your expense system, supported by receipts and logged clearly.
But if you’re providing something with personal value, like a gift card or a phone plan the employee also uses for streaming Netflix, that should be treated as a taxable benefit and reported on the T4.
A good rule of thumb is to ask whether the employee is getting a personal advantage. If the answer is yes, it’s probably a benefit.
And for those wondering how to handle reimbursements on a T4, if it needs to go there at all, it belongs in Box 40 alongside regular employment income in Box 14.
Why the CRA Cares
You might be wondering why the CRA cares so much about whether a phone bill is a benefit or a reimbursement.
Here’s why.
The CRA watches for underreported income and disguised compensation. If an employer repeatedly reimburses employees for items that look more like perks than expenses, that’s a red flag.
These are the kinds of patterns that show up as CRA audit red flags for expense reimbursements:
- Large or frequent reimbursements for the same type of item
- Missing or vague documentation
- Personal expenses passed off as business ones
- Reimbursements made instead of increasing salary or paying bonuses
When the CRA sees these, they may reassess the business or the employee’s tax return and apply interest and penalties.

Best Practices for a Business Expense Reimbursement Policy in Canada
The best way to avoid issues is to put a clear business expense reimbursement policy in place.
A strong policy includes:
- A list of reimbursable items with examples
- Documentation requirements such as receipts or mileage logs
- Deadlines for submitting claims
- Rules for mixed-use items like internet or phone plans
- CRA-compliant reimbursement rates
Having this in writing protects you in the event of a CRA review and helps your team know what’s expected.

Final Thoughts
Knowing the difference between taxable benefits vs reimbursements can save you a lot of headaches and money come tax season.
- Taxable benefits should always be reported on the T4.
- Reimbursements, when properly documented and business-related, shouldn’t.
The CRA is looking for accurate, consistent reporting, and when things are murky, that’s when the audits start.

FAQ: Taxable Benefits vs Reimbursements

No, most legitimate business reimbursements do not need to appear on a T4. However, if the reimbursement is actually a benefit in disguise, it may need to be reported. Clear classification is key.
3. How should I handle reimbursements on a T4 if they’re taxable?
If the reimbursement is deemed a taxable benefit, such as personal use of a company vehicle or gift cards, it should be included in Box 14 and Box 40 on the T4. When in doubt, consult a payroll expert.
4. What are CRA audit red flags for expense reimbursements?
Red flags include frequent or high-value reimbursements without receipts, personal expenses passed through as business costs, or patterns of reimbursing the same type of benefit instead of reporting it as income.
