1️⃣ Introduction to Employment Income and Employment Expenses
- Employment income = money and taxable benefits earned from working for an employer.
- Main source document: T4 slip.
- Employment income affects:
- Total taxable income
- Tax credits
- Refund or balance owing
- Employment expenses are deductible only if CRA conditions are met.
- Employer must complete T2200 (Declaration of Conditions of Employment).
- CRA reviews employment expense claims closely — keep receipts.
- Learn manual reporting before relying on tax software.
2️⃣ Employment Income – What Is Included
Employment income includes:
- Salary, wages, commissions
- Bonuses, overtime, vacation pay
- Severance and retiring allowances
- Taxable benefits (company car, employer-paid premiums, RRSP contributions, stock options)
- Certain reimbursements
Other related slips:
- T4A – Other employment-related income
- T4PS – Profit-sharing income (dividends)
Key rule:
👉 Most taxable benefits are calculated by the employer and already included on the T4.
3️⃣ Recording Employment Income on the T4 and T1
T4 information flows to T1 as follows:
- Box 14 → Line 10100 (Employment income)
- Box 16 (CPP) → Federal tax credit (Line 30800)
- Box 18 (EI) → Federal tax credit (Line 31200)
- Box 40 → Informational (already included in Box 14)
- Union dues → Line 21200
- RPP contributions → Deduction (affects RRSP room)
- Multiple T4s must all be entered separately.
Accuracy in box mapping prevents CRA reassessments.
4️⃣ Items to Watch for on the T4 Slip
Common mistakes:
- Ignoring lower section of T4
- Missing:
- Box 67 (Retiring allowance – Line 13000)
- Box 85 (Private health premiums – medical credit)
- Union dues
- Payroll charitable donations
- Assuming all income is in Box 14
- Rounding numbers instead of using exact figures
Best practice:
✔ Review every box
✔ Use a checklist
✔ Enter exact amounts
5️⃣ Employment Amounts on T4A and T4PS
T4A
Used for:
- Wage-loss replacement benefits
- Research grants
- Certain retirement or non-standard employment income
👉 Reported on Line 10400 (Other employment income)
T4PS
- Reports profit-sharing dividends
- Reported as dividend income (not employment income)
- Eligible dividends require gross-up calculation
Key difference:
- T4A = employment-type income
- T4PS = investment (dividend) income
6️⃣ Reporting Casual Labour, Tips & Odd Jobs (No Slip Issued)
If no T4 is issued:
- Income must still be reported.
- Report on Line 10400 as other employment income.
- Never estimate income — use client records only.
- Tips (cash or electronic) are taxable.
- Encourage clients to maintain records.
CRA audits frequently focus on unreported tips.
7️⃣ Reporting Tips & Casual Labour on the T1
Classification matters:
A. Single employer
→ Report as other employment income (Line 10400)
B. Multiple clients
→ Report as business income
→ Eligible expenses can be deducted
Examples of deductible business expenses:
- Vehicle expenses
- Advertising
- Cell phone (business portion)
Correct classification affects allowable deductions.
8️⃣ Reporting Wage-Loss Replacement Plan Income
Wage-loss benefits are taxable.
Two reporting situations:
1. Reported on T4
- Included as employment income
- Employee contributions deducted from taxable amount
2. Reported on T4A
- Insurance company specifies:
- Total benefit
- Deductible contributions
Formula:
Taxable amount = Total benefit – Employee contributions
Always verify supporting documentation.
