Strategies to Reduce or Avoid the Clawback

Before Age 65

StrategyHow It Helps
Draw down RRSP/RRIF early (60–64)Reduces future RRIF mandatory withdrawals that trigger clawback
Maximize TFSA contributionsBuild tax-free income source that doesn’t count toward clawback
Shift investments to TFSAMove from taxable/RRSP to TFSA over time
Defer OAS to age 7036% higher payment; may be worth it if income will be lower at 70

After Age 65

StrategyHow It Helps
Use TFSA for spending needsTFSA withdrawals don’t increase net income
Pension income splittingShift up to 50% of eligible pension to lower-income spouse
Capital gains timingRealize capital gains in years with lower other income
Minimize RRIF withdrawalsTake only the mandatory minimum
Consider corporate retained earningsBusiness owners can control when to pay dividends
Keep taxable investments tax-efficientReturn of capital distributions reduce taxable income

OAS Deferral (Age 65–70)

FactorDetail
Deferral increase0.6% per month deferred (7.2% per year)
Maximum deferral bonus36% higher payment if deferred to age 70
