What is a taxable benefit in Canada?

A taxable benefit is any non-cash (or near-cash) advantage or perk that your employer provides to you that CRA considers part of your employment income. Common examples include employer-paid group life insurance premiums, a company car for personal use, employer-paid parking, certain gifts and awards, and personal use of a company credit card. The value of these benefits is added to your employment income, which means you pay income tax on them even though you received goods or services rather than cash.

What is Box 40 on a T4?

Box 40 on your T4 slip is labelled "Other taxable allowances and benefits." It contains the dollar value of taxable benefits your employer has added to your employment income during the year. The amount in Box 40 is also already included in Box 14 (employment income) — so it is not an extra amount on top of Box 14, it is a breakdown showing what portion of Box 14 came from non-cash benefits. When you file your taxes, Box 14 is your total employment income and Box 40 explains part of it.

Do I owe extra tax because of Box 40?

The tax on Box 40 amounts is typically collected throughout the year via payroll withholding. When your employer adds a taxable benefit to your pay record, they also deduct additional income tax to cover it — so most employees are not surprised by a large tax bill at filing time. However, if your employer did not withhold enough (for example, if the benefit was added near year-end), you may owe a balance on your return. Box 40 can also affect your marginal tax bracket, OAS or GIS calculations, and income-tested benefits like the Canada Child Benefit.

What is the difference between a taxable benefit and a non-taxable benefit?

A non-taxable benefit is one that CRA excludes from employment income — it does not appear on your T4 and you pay no tax on it. Examples include employer-paid health and dental premiums (in most provinces), the first $500 in non-cash gifts per year (long-service awards), employee discounts that meet CRA thresholds, and subsidized meals at a workplace cafeteria (if the employee pays a reasonable price). A taxable benefit is everything else — any economic advantage the employer provides that CRA deems part of remuneration.

Can I deduct the value of a taxable benefit?

Generally no — you cannot deduct the value of a taxable benefit from your employment income. The benefit is included in your income and taxed. In some cases, if you use a taxable benefit partly for work purposes (e.g., a company car used for both business and personal travel), you can claim a deduction on Form T777 for the employment-use portion — but only for certain expenses not reimbursed by your employer. The taxable benefit itself (the standby charge for personal use) still stands.

What are the most common taxable benefits in Canada?

The most common taxable benefits in Canada include: employer-paid group life insurance premiums (any amount above the basic term coverage); personal use of a company vehicle (standby charge + operating cost benefit); employer-paid parking (if not for business use); certain employer gifts and awards over $500; travel benefits unrelated to employment duties; club memberships; personal expense reimbursements; interest-free or low-interest employee loans; and moving cost allowances exceeding the CRA-exempt amounts. Provincial differences apply — Quebec treats more benefits as taxable than other provinces.

What Are Taxable Benefits in Canada?

When your employer gives you something of value beyond your salary — a company car, paid parking, certain insurance premiums — CRA may require that value to be added to your employment income. These are called taxable benefits, and they appear in Box 40 of your T4 slip.

CRA’s Definition

Term	Meaning
Taxable benefit	Any economic advantage an employer provides to an employee (or a person connected to the employee) that CRA deems part of employment income
Near-cash benefit	Gift cards, certificates, or items easily convertible to cash — treated as cash and fully taxable
Non-cash benefit	Goods or services (company car, insurance premium) — taxable at fair market value unless CRA exempts them
Allowance	Fixed amount paid without requiring receipts — generally taxable unless CRA provides a specific exemption
Reimbursement	Employer repays employee for a specific verified expense — generally not taxable if for employment purposes

Box 40 on Your T4: How It Works

Box	Label	What it contains
Box 14	Employment income	Total employment income including all taxable benefits
Box 40	Other taxable allowances and benefits	Breakdown of non-cash/allowance benefits included in Box 14
Relationship	Box 40 is already inside Box 14 — not additional income
Tax collected	Usually via payroll throughout the year

Example: Your salary is $70,000. Your employer provides $1,200 in taxable group life insurance premiums and $1,800 in taxable parking.

Box 14 = $73,000 (salary + $3,000 benefits)
Box 40 = $3,000 (the benefit portion)

Group life insurance premiums	✅ Taxable	✅ Taxable
Vision care premiums	❌ Not taxable	✅ Taxable in Quebec

Quebec employees receiving employer-paid health and dental benefits will see these amounts included in their provincial income — the Quebec provincial return treats them as taxable employment income, even though the federal return does not.

How Taxable Benefits Are Valued

Benefit type	How CRA values it
Cash or near-cash	Face value
Goods	Fair market value (FMV) at time provided
Company car	Specific formula (standby charge + operating cost benefit)
Housing	FMV of comparable housing in the area
Low-interest loans	Difference between rate charged and CRA prescribed rate
Air travel (personal)	FMV of comparable commercial ticket

What to Do If Box 40 Is Higher Than Expected

Situation	Action
Ask employer for a breakdown	Employer must provide details of what is in Box 40
Check T4 Box 34	Contains the automobile benefit if you have a company car
Compare to prior year	Identify what changed (new benefit, different calculation)
Review with accountant	If the benefit seems wrong — CRA forms and FMV can be disputed

Bottom Line

Taxable benefits increase your employment income the same way a salary increase does — you pay income tax on the full value. Box 40 on your T4 tells you how much of your employment income came from non-cash perks rather than salary. For most employees, the tax on these benefits is collected via payroll and does not create a surprise at tax time. Where it matters most is when Box 40 pushes you into a higher marginal bracket, affects income-tested benefits, or is significantly different from what you expected — in which case getting a breakdown from your employer is the right first step.
