The FHSA Trap: How the IRS Taxes Your 'Tax-Free' Canadian First Home Savings Account in 2026

Canada's First Home Savings Account (FHSA) is the most generous registered account Ottawa has launched in years. It combines the best of both worlds: contributions are tax-deductible like an RRSP, and qualifying withdrawals to buy your first home come out completely tax-free like a TFSA. For most Canadians, it is a clear win. But if you are one of the roughly one million US citizens or green card holders living in Canada, the FHSA hides a costly mismatch — the IRS does not recognize a single one of those Canadian tax benefits, and getting it wrong can mean annual US tax bills plus foreign-trust penalties starting at $10,000 per form.

This is the same structural trap that already snares Americans with TFSAs, and the FHSA may be worse because it is newer, less understood, and being aggressively marketed to young first-time buyers — exactly the demographic least likely to have a cross-border tax advisor. Here is precisely how the FHSA looks to the IRS, the three problems it creates, and what to do if you already opened one.

What the FHSA Is (and Why Canadians Love It)

Launched in 2023, the FHSA lets a qualifying first-time home buyer contribute up to $8,000 per year, to a $40,000 lifetime maximum. On the Canadian side, the benefits stack in a way no other account does:

• Contributions are tax-deductible against your Canadian income, just like an RRSP.
• Growth is tax-free inside the account — interest, dividends, and capital gains accumulate without Canadian tax.
• Qualifying withdrawals are tax-free when used to buy a first home, like a TFSA.

For a Canadian with no US tax exposure, that triple benefit makes the FHSA almost a no-brainer. The problem is that every one of those advantages is defined by the Canadian Income Tax Act — and the US tax system simply does not honor them.

Why the IRS Doesn't See It the Way Canada Does

The US taxes its citizens and green card holders on their worldwide income regardless of where they live. The Canada-US tax treaty smooths this over for some Canadian accounts — Article XVIII specifically protects RRSPs and RRIFs, allowing US persons to defer US tax on the growth just as they do in Canada. But that protection does not extend to the TFSA, and it does not extend to the FHSA.

Worse, the IRS has issued no specific guidance on how to treat the FHSA. In that vacuum, the mainstream position among cross-border tax professionals is the conservative one: the FHSA gets no special US status. That means the Canadian deduction you claimed is worth nothing on your US return, the "tax-free" growth is fully taxable to the IRS, and the account may be treated as a foreign trust subject to onerous reporting.

The Three US Tax Problems

1. The IRS Taxes Your Growth Every Year

Because the FHSA gets no deferral under the treaty, all the income earned inside it — interest, dividends, and realized capital gains — is taxable on your US Form 1040 in the year it is earned, even though no Canadian tax applies and you never withdrew a cent. You can use foreign tax credits to offset US tax on this income, but here is the catch: since Canada doesn't tax the FHSA either, there is often no Canadian tax to credit. The result can be pure US tax on growth that both you and the CRA consider tax-free.

2. The Foreign Trust Filing Trap (Forms 3520 and 3520-A)

Depending on its legal structure, the FHSA can be treated as a foreign grantor trust for US purposes — the same debate that surrounds the TFSA. If it is, you may be required to file Form 3520 and Form 3520-A every year to report the trust. These are information returns, not tax bills — but the penalties for missing them are severe, starting at $10,000 per form, per year, even when you owe no actual tax. A young buyer who opened an FHSA and contributed $8,000 could face $20,000+ in penalties purely for failing to file forms they never knew existed.

3. The PFIC Trap on Canadian Funds

If you hold Canadian mutual funds or ETFs inside your FHSA — which is exactly what most FHSA holders do — each fund is a Passive Foreign Investment Company (PFIC) in the eyes of the IRS. PFICs carry their own punitive tax regime and require a separate Form 8621 for each fund, with interest charges that can consume much of the investment's return. This is the same issue we cover in detail in our guide to the PFIC trap on foreign mutual funds, and it stacks on top of the foreign-trust problem above.
