1. Overview
Both the Invest–Borrow–Die strategy and the Smith Manoeuvre use leverage to improve long‑term financial outcomes, but they operate in different contexts and serve different goals. This page compares the two approaches in clear, practical terms.
2. High-Level Comparison
| Feature | Invest–Borrow–Die | Smith Manoeuvre |
|---|---|---|
| Main Goal | Tax‑efficient spending and estate planning | Convert mortgage interest into deductible interest |
| Core Engine | Borrow against investments instead of selling | Borrow against home equity to invest |
| Typical Account Type | Non‑registered portfolio | Home equity + non‑registered investments |
| Time Focus | Lifetime + estate | Mortgage period + long‑term investing |
| Key Tax Lever | Capital gains deferral; possible interest deductibility | Interest deductibility; compounding |
| Risk Profile | High (large loans, market risk, rate risk) | Medium–high (leverage + housing + market risk) |
3. How Each Strategy Works
Invest–Borrow–Die
This strategy involves building a large non‑registered portfolio, borrowing against it instead of selling, and deferring capital gains as long as possible—often until death.
- Invest: Build a taxable portfolio.
- Borrow: Use the portfolio as collateral to borrow for spending or further investing.
- Die: Capital gains are triggered at death, but the loan reduces the taxable estate.
Example:
A retiree with a $2M taxable portfolio borrows $80k/year for lifestyle spending instead of selling investments.
Capital gains are deferred for decades, and the loan is repaid by the estate.
Smith Manoeuvre
A Canadian homeowner uses a re‑advanceable mortgage to convert non‑deductible mortgage interest into deductible investment loan interest.
- Pay down mortgage: Each payment reduces non‑deductible principal.
- Re‑borrow: The principal is immediately re‑borrowed to invest.
- Invest: The investment loan grows while the mortgage shrinks.
Example:
A homeowner pays $2,000/month toward their mortgage. Each month, the lender re‑advances $2,000 as an investment loan,
which is invested in income‑producing assets. Over time, the mortgage becomes fully deductible.
4. Tax Considerations (Conceptual Only)
Invest–Borrow–Die
- Capital gains are deferred by avoiding sales.
- Interest may be deductible if borrowed funds are used to invest.
- Loan reduces taxable estate at death.
Smith Manoeuvre
- Interest on investment loan may be deductible if tracing rules are followed.
- Portfolio growth ideally outpaces after‑tax interest cost.
- Requires disciplined record‑keeping.
5. Risks
Invest–Borrow–Die
- Large leverage magnifies losses.
- Market downturns can trigger margin calls.
- Rising interest rates can strain cashflow.
Smith Manoeuvre
- Leverage risk combined with housing risk.
- Requires stable income and long time horizon.
- Poor tracing can jeopardize deductibility.
6. Interaction with CRA Advantage Rules
Both strategies operate in the non‑registered world. The CRA advantage rules apply only to registered plans (TFSA, RRSP, FHSA, RESP, RDSP, RRIF).
Key point:
Advantage rules matter only if someone tries to combine these strategies with registered plans in ways that artificially shift value
or create special benefits. Used normally, neither strategy triggers advantage rules.
