📘 1. Introduction to Investment Income and Expenses
💡 What Is Investment Income?
Investment income is money earned from your money working for you, not from a job.
📊 Main Types of Investment Income
| Type | Example | Tax Treatment |
|---|---|---|
| Interest | Savings, GICs | 100% taxable |
| Dividends | Stocks, mutual funds | Lower tax (credits apply) |
| Capital Gains | Selling investments | Only 50% taxable |
👉 Key idea: Not all income is taxed the same
💸 Deductible Investment Expenses
You can reduce your taxable income with:
✔️ Investment management fees
✔️ Interest on borrowed money to invest
✔️ Accounting fees
🚫 Not allowed:
- Safe deposit box fees (no longer deductible)
⚠️ Important Rules to Know
- Income must be reported by the person who owns the investment
- You can’t shift income freely to reduce tax (attribution rules apply)
- Foreign investments may require extra reporting (T1135)
💰 2. Interest Income and Interest-Producing Investments
💡 What Is Interest Income?
Interest is money earned when you lend or deposit money.
Examples:
- Savings accounts
- GICs
- Bonds
- Loans
📌 Key Rule
👉 Interest income is 100% taxable
(No credits, no discounts)
🧾 How It’s Reported
| Slip | Source |
|---|---|
| T5 | Banks, GICs |
| T3 | Mutual funds |
👉 Both must be reported
⚠️ Even Without a Slip…
You still MUST report it
Example:
You lend someone money → earn interest → no slip
👉 Still taxable
📍 Where to Report
📄 Line 12100 – Interest & Other Investment Income
🧠 Key Takeaways
- Fully taxable income
- Report ALL sources
- Includes accrued (not yet received) interest
🧾 3. Reporting Interest Income from T5 Slips
💡 What Is a T5 Slip?
A T5 shows investment income from banks or institutions.
📌 Issued if interest > $50 (but even less must be reported)
🔍 What to Look For
- Box 13 → Interest income
- Currency (CAD or foreign)
💱 Foreign Interest (Important!)
You must convert to Canadian dollars
👉 Use Bank of Canada average exchange rate
Example:
$1,000 USD → $1,324.80 CAD (approx.)
📍 Where to Report
📄 Line 12100
👉 Add all T5 amounts together
⚠️ Common Mistakes
❌ Forgetting foreign conversion
❌ Ignoring small accounts
❌ Missing slips (CRA already has them!)
👨👩👧👦 4. Joint Investment Accounts & Income Splitting
💡 Who Reports the Income?
👉 The person who contributed the money
📊 Example
| Contribution | Income Share |
|---|---|
| Spouse A: $3,000 | 30% |
| Spouse B: $7,000 | 70% |
💡 Real-Life Rule (Simplified)
✔️ Joint accounts → usually 50/50 split accepted
⚠️ What NOT to Do
❌ Shift all income to lower-income spouse
👉 CRA may reverse it
👶 What About Children?
🚫 Cannot shift income to children (attribution rules)
🧠 Key Tip
Always be able to justify how income is split
🧾 5. Reporting Joint Account Interest on the T1 Return
💡 Key Rule
👉 Report only your share, not the full amount
🧮 Example
3 siblings share $12,000 interest
✔️ Each reports $4,000
💱 Foreign Accounts
Convert to CAD before reporting
📍 Where to Report
📄 Line 12100
⚠️ Why This Matters
CRA sees the full slip → mismatch can trigger review
🧠 Best Practice
✔️ Keep proof of ownership
✔️ Ensure all owners report correctly
📊 6. Best Practice for Allocating & Reporting Shared Income
💡 Two Methods
| Method | Risk |
|---|---|
| Report only your share | ❌ May trigger CRA mismatch |
| Report full amount + % | ✅ Best practice |
✅ Recommended Approach
👉 Report full T-slip amount
👉 Indicate your ownership %
💡 Why This Works
- Matches CRA records
- Avoids reassessment
- Easy to explain
🧠 Example
| Investment | Total | Your Share |
|---|---|---|
| Bank A | $685 | $342.50 |
| Bank B | $1,018 | $509 |
👉 Report full + percentage
🔑 Key Takeaways
- Transparency = fewer CRA issues
- Always document ownership
📘 7. Dividend Income & Types of Dividends
💡 What Are Dividends?
Money paid to you for owning shares
🎯 Why Dividends Are Special
👉 Already taxed at company level
👉 You get tax credits
📊 Types of Dividends
| Type | Source | Tax Treatment |
|---|---|---|
| Eligible | Large corporations | Lowest tax |
| Ineligible | Small businesses | Moderate tax |
| Foreign | Non-Canadian | Fully taxable |
⚙️ How It Works
- Gross-up (increase income)
- Tax credit (reduce tax)
🧠 Key Insight
👉 Dividends are usually more tax-efficient than interest
💰 8. Reporting Ineligible Dividends & Tax Credits
💡 What Are Ineligible Dividends?
Paid by small Canadian companies (CCPCs)
📍 Where to Find
- T5 → Box 10
- T3 → Box 23
🧮 How It’s Calculated
Example:
$10,000 dividend → grossed up (~15%) → $11,500 taxable
💳 Tax Credit
👉 Reduces tax payable
📍 Where Reported
- Line 12000 → taxable amount
- Schedule 1 → tax credit
🧠 Key Takeaway
✔️ Higher taxable income
✔️ BUT lower actual tax
💰 9. Reporting Eligible Dividends & Tax Credits
💡 What Are Eligible Dividends?
Paid by large Canadian corporations
👉 Most tax-efficient income
