T4 and Taxable Benefits: What Business Owners Should Double-Check Before Filing

Filing T4s this year? If you’ve got employees… even just a couple… taxable employee benefits are one of the most common spots we see small businesses get tripped up. 

Whether it’s a company vehicle, a bonus, or health coverage, failing to report the right benefits on your T4 slips can lead to headaches down the road.

In this guide, we’ll break down what are taxable benefits, how they should be reported on the T4, and what you need to double-check before filing to stay on the CRA’s good side.

What Are Taxable Benefits?

I get this question all the time: 

Wait, “what are taxable benefits?” 

And the truth is, it depends. There are many things that employees can receive instead of cold hard cash. For example: The use of a company vehicle, bonuses or incentives, gift cards and gifts, health plans or benefits, insurance plans or premiums, or even club memberships.

In other words: if it feels like a perk, it’s worth double-checking.

Common Taxable Employee Benefits to Watch For

Even if you’re running a small team or using payroll software, there are a few key areas where we often see things get missed.

These are the ones that commonly lead to CRA T4 questions.

Company Vehicles

If your employees use company vehicles for anything (yes, even just commuting), CRA sees that as a benefit.. You’ll need to calculate the standby charge and operating cost benefit and include it on their T4.

Health and Dental Plans

Many business owners ask: are employer-paid health benefits taxable in Canada? The answer is… sometimes.

Always worth a review: are health benefits taxable in Canada for all types of plans? The CRA provides guidance depending on the benefit structure, so not all health premiums are automatically exempt.

Bonuses and Incentives

Bonuses? Gift cards? Commissions?

If it’s tied to work or performance, it’s all 100% taxable. No exceptions.

These should be included in Box 14 (Employment Income) and may also need to be reflected in Box 40 depending on how they’re issued.

Gifts and Awards

While the CRA does allow some wiggle room (up to $500 per year in non-cash gifts can be tax free.)

Anything over that amount or any gift cards count as taxable employee benefits.

How to Report Taxable Benefits on the T4

When it’s time to file, here’s where you want to focus:

  • Box 14: Total employment income
  • Box 40: Other taxable benefits

Your payroll software might populate this automatically… but don’t assume. A quick manual check can save you from CRA follow-ups.

Why Missing Benefits Can Lead to CRA Reassessments

Missing taxable benefits is one of the top CRA payroll audit triggers. Their systems cross-reference:

  • Your T4 slips and summaries
  • Monthly remittances
  • Business expenses such as vehicle or insurance costs

If the numbers don’t match, they’ll come asking questions.

And sometimes? It’s the employee who ends up with a surprise tax bill. Not a great day for your team!

Quick Double-Check List Before Filing T4s

Before you hit “submit,” run through this checklist: 

  • CRA Guidance: Check what the CRA website says
  • Incentive Inclusion: Are you leaving anything out? 
  • Premium Categorization: Do you know what is taxable or not?
  • Report Matching: Does payroll match T4s?
  • Box 40 Usage: Is everything where it should be on the form?
  • Taxable Benefits: Make sure they’re identified and calculated correctly.
