FHSA room accumulates even if you don't contribute - but there's a catch

You can open a First Home Savings Account - the hybrid that gives you RRSP-style tax deductions and TFSA-style tax-free withdrawals for your first home - and never put a dollar in it. Your contribution room will still grow by $8,000 every year.

That's different from RRSPs and TFSAs, where room accumulates whether you have the account or not. With the FHSA, you must open the account first. Once you do, the room starts building automatically on January 1st of the following year.

Open an FHSA in March 2025, contribute nothing all year, and you'll still get $8,000 of new room on January 1st, 2026. Do that for five years and you'd have $40,000 of room waiting - the full lifetime limit.

The 13-year countdown

Here's what most people miss: FHSA room doesn't accumulate forever. You get a maximum of 13 years of room accumulation, starting the year after you open the account.

Open in 2025, and room stops accumulating after December 31st, 2038. It doesn't matter if you've contributed $0 or $40,000 by then - the room accumulation ends. If you haven't used the account for a first home purchase by then, you have to close it and move the money to an RRSP or RRIF.

This makes the FHSA different from every other registered account. RRSPs accumulate room based on your earned income until you're 71. TFSAs accumulate room for life, regardless of whether you contribute. The FHSA has a hard stop.

When this strategy makes sense

Opening early without contributing works if you're not ready to buy now but might be in the next decade. Maybe you're 22 and focused on paying off student loans, but you want to preserve the option to buy at 30. Or you're 28, uncertain about staying in your current city, but want the tax deduction room available if you decide to settle down.

At $80,000 in Ontario, each $8,000 FHSA contribution generates roughly $2,500 in tax refunds. TaxSplit.ca will show you the exact figure for your income and province. If you think there's even a 50% chance you'll buy in the next 10 years, having that room ready beats scrambling to catch up when you're actually house shopping.

The cost of waiting

The obvious downside: you're missing years of tax-free growth. Put $8,000 in an FHSA earning 4% annually, and it becomes $8,320 after one year. Leave the room empty, and it stays at zero. Over five years, that's the difference between $40,000 growing versus $0 growing.

But the bigger cost might be the room you never get back. Open in 2030 instead of 2025, and you've lost five years of the 13-year accumulation period. That's $40,000 of potential contribution room - gone.

If you're genuinely unsure about homeownership, opening the account preserves your options. Keeping it closed doesn't.
