You've been building up a Health Savings Account and now you're moving north. Here's what you lose, what you keep, why CRA treats the account differently than the IRS does, and why age 65 changes the entire calculation. Every rule below is traced to the statute or the treaty text.
A Health Savings Account exists because of one US statute. Section 223 of the Internal Revenue Code creates a trust (or custodial account) organized in the United States, exclusively for paying qualified medical expenses. The account itself is exempt from tax, the growth compounds tax-free, and distributions used for medical care come out tax-free. It's one of the best tax-advantaged vehicles in the US code.
Canada has no equivalent registered vehicle. The Income Tax Act doesn't contain a provision that says "if the IRC calls something tax-exempt, so do we." CRA taxes Canadian residents on worldwide income under ITA section 2(1), and a US account with a US-only exemption doesn't get a parallel pass from CRA. The exemption is statutory, domestic, and non-portable.
CRA has never published a technical interpretation, an income tax folio, or a ruling that addresses US HSAs by name. That absence is itself part of the problem: there's no official guidance telling Canadian residents exactly how to report the income from an HSA, which creates a gray area that practitioners have to navigate without a defined path.
Not clearly, and this is an area where experienced practitioners genuinely disagree.
Article XVIII of the Canada-US Tax Convention covers pensions, annuities, and social security benefits. Paragraph 3 defines "pensions" as amounts received under superannuation, pension, or other retirement arrangements. An HSA is a medical savings vehicle, not a retirement arrangement, and the treaty doesn't mention it by name.
Some practitioners point to paragraph 7, which allows deferral on income accruing in a trust or plan "operated exclusively to provide pension, retirement or employee benefits." The argument is that an HSA is operated exclusively to provide a benefit (tax-free medical savings) and therefore qualifies. The counterargument is that paragraph 7 was designed for pension and retirement vehicles, that an HSA's exclusive statutory purpose under IRC 223 is qualified medical expenses (not pension, retirement, or employee benefits), and that many HSAs aren't even employer-sponsored.
This theory is untested. CRA has not confirmed or denied it, no court has ruled on it, and the few practitioner forums that discuss it show genuine disagreement. The conservative position, and the one we'd use in the absence of a ruling, is that the treaty does not cover HSAs.
This is the most immediate practical consequence. To contribute to an HSA, you have to be an "eligible individual," and that's tested month by month. You need to be covered under a high deductible health plan on the first day of the month, and you can't be covered by any other plan that provides non-preventive-care coverage.
Canadian provincial health insurance (OHIP, MSP, AHCIP, and the rest) is universal, first-dollar coverage with no deductible. It fails the HDHP definition and constitutes disqualifying other coverage. From the first month you're enrolled in a provincial plan, you can't make new HSA contributions.
But the account itself doesn't close. Nothing in section 223 ties the account's existence to ongoing eligibility. The balance stays invested, it keeps growing tax-exempt for US purposes under section 223(e)(1), and distributions for qualified medical expenses remain tax-free on the US side. You just can't put new money in.
For 2026 the annual limits are $4,400 for self-only coverage and $8,750 for family coverage, with an extra $1,000 catch-up if you're 55 or older. Those figures come from Rev. Proc. 2025-19 and are indexed annually. Once provincial coverage starts, they drop to zero.
This is the part most people miss. Qualified medical expenses are defined by cross-reference to section 213(d) of the IRC, which describes "medical care" without any geographic restriction. A doctor visit in Toronto, a prescription filled in Vancouver, dental work in Montreal: all qualify as long as the expense meets the section 213(d) definition. The location of the provider isn't the test. The nature of the expense is.
That makes a sitting HSA balance genuinely useful after the move, not just a trapped asset. Out-of-pocket dental, vision, physiotherapy, prescriptions not covered by your provincial plan, private health insurance premiums: these are all section 213(d) expenses, and paying them from the HSA keeps the distribution tax-free on the US side.
The Canadian side is a separate question. Whether CRA taxes the distribution depends on how they classified the account's income in prior years and whether the growth was already picked up on your T1. That's where the gray area lives, and it's why these files need a two-country view rather than a US-only one.
| While you live in the US | After you move to Canada | |
|---|---|---|
| Contributions | Deductible above the line. $4,400 self / $8,750 family for 2026, plus $1,000 catch-up if 55+. | Zero. Provincial health insurance disqualifies you from contributing. |
| Growth | Tax-free under IRC 223(e)(1). | Still tax-free for US purposes. Likely taxable annually by CRA, since the treaty doesn't clearly cover it. |
| Medical distributions | Tax-free for qualified medical expenses under section 213(d). | Still tax-free for US purposes. Section 213(d) has no geographic restriction, so Canadian medical expenses qualify. |
| Non-medical distributions (before 65) | Included in income, plus 20% additional tax. | Same US treatment. Canadian treatment depends on how CRA classified the account. |
| Non-medical distributions (65+) | Included in income. No penalty. Works like an IRA. | Same US treatment. CRA taxes as income regardless of age. |
| Reporting | Form 8889 with the return. Form 5498-SA from the custodian. | T1135 if total specified foreign property exceeds $100K CAD. Possible trust reporting depending on CRA classification. |
Before age 65, pulling money out of an HSA for anything other than medical expenses costs you: ordinary income tax plus a 20% additional tax on the includible amount. After 65, the 20% goes away. The account effectively becomes an IRA: withdraw for any reason, pay ordinary income tax, no penalty.
Medical distributions remain completely tax-free at any age. So after 65, an HSA is strictly better than an IRA for the same dollars: medical spending comes out tax-free, and everything else comes out at the IRA rate. That makes the planning question for someone moving to Canada at 55 very different from someone moving at 35.
The other two exceptions to the 20% penalty are death and disability. There's no exception for moving abroad, losing HDHP coverage, or becoming a Canadian resident. Emigration doesn't unlock a penalty-free window.
This is the cleanest path for most people. The account stays open, you use it for out-of-pocket medical costs in Canada (dental, vision, prescriptions, anything provincial insurance doesn't cover), and each distribution is tax-free on the US side. The balance draws down over time without triggering the 20% penalty, and you're paying for expenses you'd have paid anyway.
The Canadian reporting obligation and possible annual tax on the growth are the costs of this approach. Whether those costs matter depends on the balance: $8,000 in the account with $2,000 a year in dental bills is a different calculation from $80,000 sitting in an index fund.
If you're within striking distance of 65 and the balance is large, waiting can make sense. At 65 the 20% penalty disappears and every dollar becomes accessible at ordinary income tax rates. You still get tax-free treatment on medical distributions, and the non-medical money comes out the same way an IRA distribution would. The Canadian annual tax on the growth is the carrying cost.
The entire withdrawal that isn't allocable to medical expenses is included in gross income, and the 20% additional tax applies on top. For someone under 65 with a large balance, that's a heavy hit. The only scenario where this makes sense is a small balance where the Canadian reporting burden isn't worth maintaining, and the tax plus penalty is a rounding error.
One more thing on the penalty: the 20% is an additional US tax, and it may not be creditable against your Canadian tax as a foreign tax credit. CRA's general position is that penalties are not "income tax" for FTC purposes. That means you could pay US income tax, the 20% US penalty, and Canadian tax on the same dollars, with a credit only for the income-tax portion.
If you have medical expenses you've been deferring (dental work, elective procedures, new glasses), spending the HSA down while you're still a US resident avoids the Canadian reporting and classification question entirely. The distributions are tax-free for qualified medical expenses, and the account doesn't cross the border with a balance CRA needs to deal with.
If the HSA balance is under $5,000 and you've got dental bills that will use it up in a year, you probably don't need us. Spend it down on qualified medical expenses and move on.
The files that need a CPA are the ones with five- or six-figure balances, someone close to 65 who's weighing the IRA-like option, or a household where the HSA sits alongside RRSPs, 401(k)s, and other cross-border accounts that all have to be reported correctly on both returns. Those need the two-country picture worked out before anything moves.
The Cross-Border Assessment is a flat $250, USD. An hour with a CPA licensed in both countries, then a written summary of your file with a firm quote for whatever the work turns out to be. Credits in full toward the engagement.
If your total specified foreign property exceeds $100,000 CAD in cost at any time during the year, you have to file Form T1135 under section 233.3 of the ITA. An HSA holding cash and investments is not personal-use property, so it counts toward that threshold alongside any US brokerage accounts, IRAs, 529 plans, and other foreign holdings.
The threshold is based on cost, not fair market value, and it's measured in Canadian dollars. A $30,000 HSA on its own probably doesn't trigger T1135, but combined with a 401(k), an IRA, and a US bank account, it pushes a lot of people over the line.
Whether additional trust reporting applies (Forms T1141 or T1142) depends on how CRA classifies the HSA structure. Practitioners have identified three possibilities: offshore investment fund property under ITA section 94.1, a foreign trust under section 94, or simply a foreign investment account with annual income inclusion. Each carries different forms and different penalties for getting it wrong. No published CRA ruling resolves the question specifically for HSAs, so the classification is worth raising with your preparer rather than guessing.
There's no clean mirror here. Canada's closest equivalent to the HSA concept is the employer-sponsored Private Health Services Plan (PHSP) or Health Care Spending Account (HCSA), but these are fundamentally different: they're employer-funded, use-it-or-lose-it arrangements, not individual savings accounts that grow over time. Canada has no registered medical savings vehicle that parallels the HSA.
The RRSP is the Canadian registered account that most commonly crosses the border in the other direction, and it actually does have treaty protection under Article XVIII(7). That's the provision some practitioners try to stretch to cover HSAs, and it's worth understanding why it works for RRSPs but not clearly for HSAs: an RRSP is explicitly a retirement arrangement, it's named in the treaty, and both countries have agreed on its treatment. An HSA is a medical savings vehicle that neither treaty nor ITA addresses.
