Estimated Tax Erosion Score40 / 100

2 / 7 erosion factors selected

Potential 15-Year Wealth Drag-$26,200

Select the potential friction points in your current setup:

1. Funding RRSP (HBP) Before Maxing Out Your $8,000/yr FHSA Room-$11,400 (18 %)

HBP withdrawals must be repaid over 15 years with after-tax dollars, whereas qualifying FHSA withdrawals are 100% tax-free and never repaid.

2. Holding High-Fee Series A Bank Mutual Funds (~2.05% MER) Inside FHSA/RRSP-$14,800 (22 %)

A 1.80% annual MER gap erodes over 25% of your compounded down payment capital across a 10-to-15-year accumulation window.

3. Waiting Until You Have $8,000 to Open Your FHSA (Instead of Opening Before Dec 31)-$3,200 (12 %)

Unlike the TFSA, FHSA contribution room only starts accumulating in the calendar year you officially open the account.

4. Spending the Spring Tax Refund Instead of Reinvesting It-$6,900 (15 %)

The mathematical edge of both the FHSA and RRSP depends on compounding the upfront tax refund (MTR × Contribution).

5. Ignoring the 15-Year Mandatory HBP Repayment Cash-Flow Drag (1/15th per year)-$5,600 (14 %)

On a $60,000 HBP withdrawal, you must allocate $4,000/year of after-tax savings for 15 years or face annual taxable income inclusion.

6. Claiming the Tax Deduction Immediately Before a Major Income Jump-$3,800 (10 %)

Deducting at a 28% marginal rate when you expect to reach a 45% bracket within 18 months forfeits 17% in permanent tax alpha.

7. Mismatching FHSA Asset Allocation with Your Target Closing Date-$2,900 (9 %)

Suffering a -25% equity drawdown 6 months before closing on a property wipes out years of accumulated tax alpha.
