Most cross-border tax questions have an answer somebody doesn’t like. The First Home Savings Account presents something rarer: a question without a settled answer at all.

Canada launched the FHSA in 2023 — deductible going in, tax-free coming out for a first home, a genuinely attractive hybrid. What Canada did not do, and could not do, is tell the US how to treat it. And the US, as of July 7, 2026, has not issued FHSA-specific guidance.

What is actually known

Three things can be stated with confidence.

First, there is no provision in the Canada–US treaty written with the FHSA in mind — the treaty predates the account by decades, and nothing in it obviously extends the RRSP-style deferral (RRSPs and the IRS: What the Treaty Handles Automatically — and What It Doesn’t ) to this new vehicle.

Second, the account may still create U.S. reporting questions regardless of how the income-tax treatment resolves. A US person’s FHSA is a foreign financial account like any other for disclosure purposes (Three Disclosure Regimes, Three Different Rules: T1135 vs FBAR vs Form 8938).

Third, the uncomfortable pattern from the TFSA is the obvious precedent: a Canadian account with no treaty recognition, whose tax-free status Canada grants and the US ignores (The TFSA Trap: Tax-Free in Canada, Taxable in the US) — with a possible foreign-trust characterization question that may also need to be considered, depending on how advisers classify the arrangement and whether future guidance addresses it.

What is not known — and why that’s the real point

Whether the US will tax FHSA growth as it accrues; whether the account risks trust-classification paperwork; whether future guidance or a treaty update will resolve it favorably — these are open. Practitioners have staked out positions, and the positions differ. Anyone who tells a US person the FHSA is “fine” or “a disaster” with certainty is ahead of the actual state of the guidance.

For an individual, uncertainty is itself information. An account whose US treatment is unresolved carries three practical implications: the conservative path is to assume no US shelter until told otherwise; the account’s records need keeping in a form that supports whichever treatment eventually applies; and the decision to open one as a US person is a bet that should be made knowingly, usually with advice, rather than at a bank counter.

Why this page exists

This is a topic where the date at the top of the article genuinely matters. Guidance could arrive; positions could consolidate; a treaty protocol could someday moot the question. This page will be updated as that happens — and its review date is the fastest way to check whether “still unresolved” is still true.
