Strategies to Reduce or Avoid the Clawback
Before Age 65
| Strategy | How It Helps |
|---|---|
| Draw down RRSP/RRIF early (60–64) | Reduces future RRIF mandatory withdrawals that trigger clawback |
| Maximize TFSA contributions | Build tax-free income source that doesn’t count toward clawback |
| Shift investments to TFSA | Move from taxable/RRSP to TFSA over time |
| Defer OAS to age 70 | 36% higher payment; may be worth it if income will be lower at 70 |
After Age 65
| Strategy | How It Helps |
|---|---|
| Use TFSA for spending needs | TFSA withdrawals don’t increase net income |
| Pension income splitting | Shift up to 50% of eligible pension to lower-income spouse |
| Capital gains timing | Realize capital gains in years with lower other income |
| Minimize RRIF withdrawals | Take only the mandatory minimum |
| Consider corporate retained earnings | Business owners can control when to pay dividends |
| Keep taxable investments tax-efficient | Return of capital distributions reduce taxable income |
OAS Deferral (Age 65–70)
| Factor | Detail |
|---|---|
| Deferral increase | 0.6% per month deferred (7.2% per year) |
| Maximum deferral bonus | 36% higher payment if deferred to age 70 |
| Break-even age | Approximately 82–83 (if you live past this, deferral pays off) |
| When to defer | High income at 65 (clawback would erode OAS anyway) |
| When NOT to defer | Low income, need the money, poor health |
Deferral Example
| Start Age | Monthly OAS | Annual OAS | Increase vs 65 |
|---|---|---|---|
| 65 | $727 | $8,724 | — |
| 66 | $779 | $9,352 | +7.2% |
| 67 | $832 | $9,981 | +14.4% |
| 68 | $884 | $10,610 | +21.6% |
| 69 | $936 | $11,238 | +28.8% |
| 70 | $989 | $11,864 | +36.0% |
