A Quick Guide for Tax Preparers & DIY Filers
Many employees spend their own money to do their job — whether it’s vehicle costs, office supplies, or working from home.
But here’s the catch:
Not all work-related expenses are deductible.
The CRA has strict rules about what employees can claim, who qualifies, and what documentation is required.
This guide breaks down the 19 key concepts every tax preparer or self-filer should understand.

1️⃣ Employment Expenses – What Cannot Be Claimed
Before learning what you can deduct, you must understand what you cannot deduct.
🚫 Non-Deductible Expenses
| Expense | Why Not Allowed |
|---|---|
| Commuting to work | Considered personal travel |
| Business clothing | Personal clothing |
| Haircuts or grooming | Personal expense |
| Gym memberships | Personal benefit |
| Meals during regular workday | Personal consumption |
⚠️ Key Rule
If an expense is personal in nature, it cannot be deducted — even if it helps you perform your job better.
2️⃣ Who Can Claim Employment Expenses (Eligibility Rules)
Not every employee qualifies to deduct work expenses.
✅ You can claim employment expenses if:
- Your employment contract requires you to pay for certain expenses
- Your employer does not reimburse you
- You have a signed T2200 form
Example
| Situation | Deductible? |
|---|---|
| Using your own vehicle for work travel | ✅ Yes |
| Driving to your regular office | ❌ No |
| Receiving non-taxable vehicle allowance | ❌ No |
3️⃣ The T2200 Form – Declaration of Conditions of Employment
The T2200 form is one of the most important documents when claiming employment expenses.
📄 Purpose of T2200
It confirms:
- The employee must pay certain expenses
- Whether the employee travels for work
- If the employee receives allowances or reimbursements
- If the employee works from home
⚠️ Important
| Rule | Explanation |
|---|---|
| Employer must complete the form | Employees cannot create it |
| Must be signed | Unsigned forms are invalid |
| Not filed with return | Keep it for CRA review |
4️⃣ The T777 Form – Statement of Employment Expenses
Once eligibility is confirmed using T2200, expenses are calculated on Form T777.
🧾 Purpose
The T777 lists all deductible expenses such as:
- Vehicle expenses
- Home office expenses
- Office supplies
- Work phone costs
- Advertising (for commission employees)
Flow of Forms
| Form | Purpose |
|---|---|
| T2200 | Confirms eligibility |
| T777 | Calculates expenses |
| T1 Return | Reports deduction |
5️⃣ Framework for Deducting Employment Expenses
Claiming employment expenses follows a clear process.
Step-by-Step Framework
1️⃣ Obtain signed T2200
2️⃣ Review allowed expenses
3️⃣ Collect receipts and records
4️⃣ Complete T777
5️⃣ Apply employment-use percentages
6️⃣ Exclude reimbursements
7️⃣ Enter deduction on Line 22900
6️⃣ Example: Vehicle Expense Deduction
Vehicle expenses are one of the most common employment deductions.
Example Scenario
Jason uses his personal truck for work.
| Expense | Amount |
|---|---|
| Fuel | $6,000 |
| Repairs | $2,500 |
| Insurance | $2,200 |
| Lease payments | $6,500 |
| Other costs | $544 |
| Total | $17,744 |
If 66% of driving is for work:
$17,744 × 66% = $11,771 deductible
7️⃣ Two Types of Vehicle Allowances
Employers may compensate employees for vehicle use in two ways.
🚗 Vehicle Allowance Types
| Type | Tax Treatment |
|---|---|
| Flat monthly allowance | Taxable |
| Per-kilometre reimbursement | Usually non-taxable |
Understanding this difference is essential for correct deductions.
8️⃣ When a Flat Vehicle Allowance Is Received
A flat allowance (example: $600/month) is always taxable.
How It Works
1️⃣ Allowance appears on the T4 slip
2️⃣ It increases employment income
3️⃣ Employee can claim actual vehicle expenses
9️⃣ When a Per-Kilometre Allowance Is Received
If the employer reimburses based on actual kilometres driven, the payment may be non-taxable.
Example
Jason drives 19,185 km for work.
Allowance:
19,185 × $0.46 = $8,825
Because the rate is reasonable:
- Not included on T4
- No tax payable
🔟 When Reimbursement Does Not Cover All Costs
Sometimes reimbursement is less than actual expenses.
Two Ways to Handle It
| Method | Explanation |
|---|---|
| Add reimbursement to income | Deduct full expenses |
| Subtract reimbursement | Deduct only the difference |
Both methods lead to the same result.
1️⃣1️⃣ Home Office Expenses – What Can Be Claimed
Employees working from home may deduct certain expenses.
Eligible Expenses
| Expense | Deductible |
|---|---|
| Electricity | ✅ |
| Heating | ✅ |
| Water | ✅ |
| Internet (monthly fees) | ✅ |
| Rent (if renting) | ✅ |
Commission employees may also claim:
- Home insurance

1️⃣2️⃣ Home Office Expense Example
Example:
| Expense | Annual Amount |
|---|---|
| Rent | $18,000 |
| Utilities | $2,400 |
| Internet | $600 |
Workspace = 10% of home
Deduction:
| Expense | Deductible |
|---|---|
| Rent | $1,800 |
| Utilities | $240 |
| Internet | $60 |
Total deduction = $2,100
1️⃣3️⃣ Example of Other Employment Expenses
Employees may also claim work-related costs such as:
- Parking
- Office supplies
- Cell phone usage
- Postage
- Small maintenance items
Example:
| Expense | Amount |
|---|---|
| Cell phone | $750 |
| Parking | $400 |
| Supplies | $466 |
Total = $1,616
1️⃣4️⃣ Example with Reimbursed Expenses
If the employer reimburses certain expenses:
❌ Those expenses cannot be deducted.
Example:
| Expense | Reimbursed | Deductible |
|---|---|---|
| Parking | Yes | ❌ |
| Office supplies | Yes | ❌ |
| Vehicle allowance | Taxable | ✅ |
1️⃣5️⃣ Special Rules for Commission Employees
Employees paid by commission have additional deductions available.
They may claim:
- Advertising expenses
- Promotion costs
- Property taxes (home office)
- Home insurance
- Certain travel expenses
But they must:
- Earn commission income

| Advertising | $1,200 |
| Home office | $1,400 |
Total employment expenses = $8,800
1️⃣7️⃣ Additional Expenses That Cannot Be Deducted
Even if work-related, some expenses remain non-deductible.
Examples include:

These are considered capital or personal expenses.
