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 $752 $9,024
66 $806 $9,673 +7.2%
67 $860 $10,323 +14.4%
68 $914 $10,973 +21.6%
69 $969 $11,622 +28.8%
