Mutual Fund & ETF Tax Guide
Two Tax Events
Mutual funds and ETFs can trigger tax in two ways: (1) distributions the fund pays you, and (2) capital gains when you sell. Both need proper tracking for accurate reporting.
Types of Fund Distributions
Canadian Dividends
- Eligible and non-eligible dividends
- Dividend tax credit applies
- Reported on T3 slip
- Gross-up and credit treatment
Capital Gains
- Fund sells securities at a profit
- Passed through to unitholders
- 50% inclusion rate
- Taxable even if reinvested
Interest and Foreign Income
- 100% taxable
- From bonds, foreign dividends
- No special credits
Return of Capital (ROC)
- Not immediately taxable
- Reduces your ACB
- Results in larger capital gain when sold
- Common with certain funds
Key Point: You pay tax on distributions even if they're reinvested. The reinvested amount increases your ACB, so you're not taxed twice.
Understanding Your T3 Slip
Key boxes on the T3:
| Box | Description | Tax Treatment |
|---|---|---|
| 21 | Capital gains | 50% taxable |
| 23 | Actual eligible dividends | Gross-up 38% |
| 32 | Other income | 100% taxable |
| 42 | Return of capital | Reduces ACB |
| 26 | Other dividends | Gross-up 15% |
Adjusted Cost Base (ACB) Tracking
Why ACB Matters
- Determines your capital gain/loss when selling
- Changes with each purchase, sale, and ROC
- Must track yourself for non-registered accounts
ACB Calculation
- Purchases: Add cost to ACB
- Reinvested distributions: Add to ACB
- Return of capital: Subtract from ACB
- Sales: Reduce ACB proportionally
Example
- Buy 100 units at $10 = $1,000 ACB
- Reinvest $50 distribution (5 units at $10)
- New ACB: $1,050 for 105 units
- ACB per unit: $10
- Receive $30 ROC
- New ACB: $1,020
- ACB per unit: $9.71
Warning: If you don't track ACB properly, you may pay too much tax. If ROC reduces your ACB to zero, further ROC becomes an immediate capital gain.
ETFs vs Mutual Funds
Tax Efficiency
- ETFs generally more tax-efficient
- In-kind creation/redemption reduces gains
- Less portfolio turnover
- Fewer surprise capital gains distributions
Mutual Fund Issues
- Can distribute large capital gains
- Especially if other investors redeem
- You pay tax on gains you didn't benefit from
- More common at year-end
Selling Fund Units
Capital Gain/Loss Calculation
- Proceeds minus ACB = capital gain/loss
- 50% inclusion rate
- Report on Schedule 3
Selling Part of Your Holdings
- Use average cost method
- Total ACB ÷ Total units = ACB per unit
- Reduce ACB by cost of units sold
Reinvested Distributions
How They Work
- Distribution used to buy more units
- Still taxable in year received
- New units have ACB = distribution amount
Record Keeping
- Track each reinvestment
- Keep all T3/T5 slips
- Use spreadsheet or software
- Broker statements help but aren't complete
Phantom Distributions
You may owe tax without receiving cash:
- Capital gains distributed but reinvested
- Must have cash to pay tax
- Common surprise for new investors
- Check fund's distribution history
Year-End Planning
Before Buying
- Check fund's distribution schedule
- Avoid buying just before large distribution
- December distributions common for mutual funds
- You'd pay tax on gains you didn't participate in
Tax-Loss Harvesting
- Sell losing positions to offset gains
- Wait 30 days to repurchase (superficial loss rule)
- Can buy similar but not identical fund
Funds in Different Accounts
Non-Registered
- All distributions taxable
- Must track ACB
- Prefer tax-efficient funds (ETFs, low turnover)
TFSA
- No tax on distributions or gains
- No need to track ACB for tax
- US dividend withholding still applies
RRSP
- No current tax on distributions
- All withdrawals taxed as income
- Good for interest-generating funds
- US dividends exempt from withholding
Asset Location Strategy
Optimize fund placement across accounts:
- TFSA: High-growth potential
- RRSP: Bonds, US dividends
- Non-registered: Canadian dividends, tax-efficient ETFs
Foreign Content in Funds
US-Listed ETFs
- 15% withholding on distributions
- May not be recovered in TFSA
- Exempt in RRSP
- Claim foreign tax credit in non-registered
Canadian-Listed Funds Holding Foreign Securities
- Foreign withholding may be embedded
- Some funds claim treaty benefits
- Check fund documentation
Common Mistakes
- Not tracking reinvested distributions: Overpay tax
- Ignoring return of capital: Wrong ACB
- Buying before distribution: Unnecessary tax
- Using broker's cost basis: May be wrong
- Not reporting T3 slips: CRA has copies
