Withdrawal-side clawbacks can push the effective retirement rate above the statutory bracket — always model them.4344## Worked example: FHSA for a first home4546Buyer at 30% marginal rate contributes $8,000/yr for 5 years ($40,000 lifetime max):47- Deductions refund 30% × $40,000 = **$12,000** along the way.48- Suppose the account grows to $48,000 → withdrawn **tax-free** for a qualifying first home.49- The same money in a TFSA: no $12,000 refund. Via RRSP + Home Buyers' Plan: withdrawal must be repaid over 15 years or it becomes taxable income. FHSA dominates for this goal.5051## Worked example: superficial-loss harvesting5253$12,000 loss on a Canadian index ETF in November:541. Sell with settlement before Dec 31; buy a different-index ETF the same day to stay invested.552. The capital loss offsets capital gains this year; unused losses carry back 3 years (T1A request) or forward indefinitely.563. At a 50% inclusion rate and 40% marginal rate, offsetting $12,000 of gains saves ≈ **$2,400**.574. Check ±30 days for purchases of the identical fund by you, your spouse, your RRSP/TFSA, or a corporation you control — a match denies the loss (and in registered accounts the denied loss is gone permanently, no basis bump).5859## Worked example: donation pooling and carry-forward6061Couple each gives $150/yr to charity, claimed separately every year.62- Federal credit: 15% on the first $200, 29% above — separate $150 claims never reach the higher tier.63- **Pooled and carried:** accumulate 5 years of both spouses' donations ($1,500) and claim once on the higher earner's return: 15% × $200 + 29% × $1,300 = **$407 federal** (plus provincial), vs $225 claimed annually-and-separately.64- Rule of thumb: pool spouses always; carry forward (max 5 years) whenever annual totals are small.6566## Asset-location placement table6768Fill registered room with the worst-taxed assets first.6970| Asset type | Taxable-account treatment | Priority for RRSP/TFSA shelter |71|---|---|---|72| Interest (bonds, GICs, HISA) | 100% at full marginal rate | **Highest** |73| Foreign dividends | Full rate + possible withholding | High (US withholding exempt in RRSP under treaty, NOT in TFSA) |74| Canadian eligible dividends | Dividend tax credit — low effective rate | Low — fine in taxable |75| Capital gains | 50% inclusion, deferrable until sale | Lowest — fine in taxable |7677## Retirement decumulation notes (RRIF, OAS)7879- RRSP converts to a RRIF by end of the year the holder turns 71; mandatory minimum withdrawals begin the next year and rise with age.80- Withdrawals are ordinary income: large RRSP balances can push retirees into OAS clawback (15% on income above the threshold — verify the current threshold on canada.ca).81- Planning levers: draw RRSP down early in low-income retirement years (before OAS/CPP start), base RRIF minimums on the younger spouse's age, and shift surplus withdrawals into the TFSA.8283## Contribution-room mechanics and deadlines8485| Account | 2026 figure | Deadline | Mechanics |86|---|---|---|---|87| RRSP | 18% of prior-year earned income, max $33,810 | Mar 2, 2026 for 2025 deduction | Room carries forward; deduction can also be deferred to a higher-income year |88| TFSA | $7,000/yr; $109,000 cumulative since 2009 | none | Withdrawals restore room the following Jan 1 — recontributing the same year over-contributes |89| FHSA | $8,000/yr; $40,000 lifetime | Dec 31 | Only $8,000 of unused room carries forward; must open the account to start accruing |90| RESP | $2,500/child/yr for full CESG | Dec 31 | CESG 20%, $500/yr, $7,200 lifetime; catch-up limited to one extra year at a time |9192Verify personal room in CRA My Account — never estimate it from salary alone (pension adjustments reduce RRSP room).9394## Gotchas9596- **RRSP over-contribution:** 1%/month penalty tax on amounts more than $2,000 over your limit — file T1-OVP if it happens; withdraw the excess promptly.97- **TFSA same-year recontribution:** withdrawing $10k in March and redepositing in June over-contributes unless room remained; the room comes back Jan 1.98- **Spousal RRSP attribution:** withdrawals within 3 calendar years of any spousal contribution attribute back to the contributor.99- **TOSI:** dividends/gains from a related private corporation to family members are taxed at the top rate unless an exclusion applies (e.g., 20+ hrs/week active work) — this killed income sprinkling.100- **Superficial loss includes registered accounts:** repurchasing inside an RRSP/TFSA denies the loss with no cost-base adjustment — the worst outcome.101- **OAS clawback:** retirement income above the annual threshold claws back OAS at 15% — RRSP/RRIF withdrawals count, TFSA withdrawals don't; model it before large RRSP balances build.102- **Deferring the RRSP deduction:** contributing now but deducting in a future higher-rate year is legal and often forgotten.103- **Québec:** separate return, different rates and credits — federal-only math understates everything.104
