The FHSA is sometimes called the best registered account in Canada, and the reason is its unique three-part tax structure. No other account offers all three of these benefits at once.
Your contributions are tax-deductible. Like an RRSP, the money you put into your FHSA reduces your taxable income for the year. If you contribute $8,000 and your marginal tax rate is 30%, that's $2,400 back on your tax return. (For a broader look at what homeowners can and can't deduct, see our guide to Canadian homeowner tax write-offs.)
Your investments grow tax-free. Like a TFSA, any interest, dividends, or capital gains earned inside the account are completely sheltered from tax while they remain in the FHSA.
Your qualifying withdrawals are tax-free. When you use the money to buy your first home, you pay no tax on the withdrawal — not on your contributions, and not on the growth. Unlike the Home Buyers' Plan, there's nothing to repay.
Here's what that looks like in practice. Say you contribute $8,000 per year for five years in a 30% marginal bracket, and your investments earn a modest 5% annually. After five years, you'd have approximately $44,200 in your FHSA (your $40,000 in contributions plus roughly $4,200 in growth). You would have received about $12,000 in total tax refunds over the five years. And you'd withdraw the entire $44,200 tax-free for your home purchase. That's over $16,000 in combined tax benefits — from a single account.
You can defer your FHSA tax deduction to a future year when your income — and your marginal tax rate — is higher. If you're early in your career and expect your income to rise, contributing now but claiming the deduction later can maximize the value of your refund. The deduction is reported on line 20805 of your federal return.
