What Are Taxable Benefits in Canada? | Box 40 on Your T4 Explained

Updated

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. This page explains the general rules; the directory of taxable employment benefits has a separate guide for each common benefit.

CRA’s Definition

TermMeaning
Taxable benefitAny economic advantage an employer provides to an employee (or a person connected to the employee) that CRA deems part of employment income
Near-cash benefitGift cards, certificates, or items easily convertible to cash: treated as cash and fully taxable
Non-cash benefitGoods or services (company car, insurance premium): taxable at fair market value unless CRA exempts them
AllowanceFixed amount paid without requiring receipts: generally taxable unless CRA provides a specific exemption
ReimbursementEmployer repays employee for a specific verified expense: generally not taxable if for employment purposes

Box 40 on Your T4: How It Works

BoxLabelWhat it contains
Box 14Employment incomeTotal employment income including all taxable benefits
Box 40Other taxable allowances and benefitsBreakdown of non-cash/allowance benefits included in box 14
RelationshipBox 40 is already inside box 14, not additional income
Tax collectedUsually 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)

The T4 slip guide covers the other boxes on the slip.

How a Taxable Benefit Is Taxed

Taxable benefits increase your employment income the same way a salary increase does: you pay income tax on the full value at your marginal rate. Because the benefit is already in box 14, there is nothing extra to report on your return, and for most employees the tax is collected through payroll during the year. What the benefit costs you in tax depends on your marginal rate:

Annual taxable benefitAdditional tax at 30% marginal rateAt 40% marginal rate
$300~$90~$120
$600~$180~$240
$1,200~$360~$480
$2,400~$720~$960

Where it matters most is when box 40 pushes part of your income into a higher marginal bracket, raises the income that income-tested benefits are based on, or is significantly different from what you expected.

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. The guide to whether employer health and dental plans are taxable covers the RL-1 box J reporting.

How Taxable Benefits Are Valued

Benefit typeHow CRA values it
Cash or near-cashFace value
GoodsFair market value (FMV) at time provided
Company carSpecific formula (standby charge + operating cost benefit)
HousingFMV of comparable housing in the area
Low-interest loansDifference between rate charged and CRA prescribed rate
Air travel (personal)FMV of comparable commercial ticket

If Box 40 Is Higher Than Expected

StepWhat it tells you
Ask employer for a breakdownEmployer must provide details of what is in box 40
Check T4 box 34Contains the automobile benefit if you have a company car
Compare to prior yearIdentifies what changed (new benefit, different calculation)
Review with an accountantIf the benefit seems wrong: CRA forms and FMV can be disputed

A bonus is cash pay rather than a benefit, so it is taxed through withholding instead of box 40; the guide on what to do when you get a bonus covers it.
