Work Income and Deductions

Understand how employment income is reported, what expenses can be deducted, and how to reduce your taxable income through eligible claims

Getting Started with Employment Income & Deductions

For most Canadians, employment income forms the core of their financial picture. But knowing what qualifies as taxable income and what expenses you can claim can make a real difference at tax time. Whether you work from home, cover your own supplies, or use your vehicle for work, this guide will help you understand the rules and avoid missing valuable deductions.

What Counts as Employment Income?

Employment income includes more than just your regular salary or wages. It also covers bonuses, commissions, tips, and certain benefits provided by your employer. Everything reported on your T4 slip must be included in your return, so it's important to understand the full scope of what counts as income.

What are Employment Deductions ?

If you pay out of pocket for certain work-related costs, you may be eligible to deduct those expenses when you file your return. These deductions are not automatic. You need to meet specific conditions, have your employer complete the necessary forms, and keep documentation that supports your claim.

Common deductions include home office expenses, supplies, internet costs, professional dues, and vehicle use for work purposes. Each type of deduction comes with its own criteria, which we’ll walk through in this guide.

Why Understanding These Rules Matters

Without a good understanding of what expenses are deductible and how to claim them properly, you may end up overpaying in taxes. On the other hand, claiming ineligible expenses could create problems if your return is reviewed by the CRA. By learning the basics, you can reduce your tax burden while staying compliant with the rules.

Whether you work in an office, from home, or out on the road, understanding how to manage employment income and deductions is essential for getting the most from your return.
