HSA for US expats: IRS rules, 2026 limits, and using HSA funds abroad
For US expats, a health savings account can be one of the most valuable financial tools you carry abroad, but the IRS HSA rules around contributing, spending, and reporting change the moment you leave the US.
US expats can generally use existing health savings account (HSA) funds abroad for qualified medical expenses, but many cannot keep contributing after they lose qualifying US high deductible health plan (HDHP) coverage.
For tax year 2025 (filed in 2026), the IRS HSA contribution limits are $4,300 self-only and $8,550 family, with a $1,000 catch-up contribution at age 55 or older. All activity is reported on Form 8889 attached to Form 1040, 1040-SR, or 1040-NR.
The core distinction is this: using existing HSA funds abroad is generally allowed, but making a new health savings account contribution often is not, because most foreign health plans do not meet IRS HDHP requirements under IRC § 223(c)(2).
Key figures for tax year 2025 (filed in 2026):

- Catch-up contribution at age 55 or older: $1,000
- HDHP minimum deductible: $1,650 self-only and $3,300 family
- HDHP maximum out-of-pocket: $8,300 self-only and $16,600 family
- Reporting form: Form 8889, attached to Form 1040, 1040-SR, or 1040-NR
Can you use an HSA in another country?
Yes, a health savings account (HSA) can generally be used for qualified medical expenses incurred abroad. What matters is not the country where the expense occurred, but whether the expense itself qualifies under IRS definitions in IRC § 213(d) and is properly documented.
An expat who sees a doctor in Germany, gets dental work done in Mexico, or fills a prescription in Japan can pay from an HSA, as long as the expense meets IRS rules in Publication 969.
Even when the tax rule permits an expense, the HSA card or plan administrator may impose its own restrictions on international transactions. Confirm with your HSA provider before relying on the card abroad.
What is an HSA, and why does the IRS treat it as tax-advantaged?
An HSA is a tax-exempt trust or custodial account – sometimes called a tax-exempt health savings account – that lets eligible individuals save for qualified medical expenses. The IRS gives HSAs a three-part tax advantage under IRC § 223.
The three health savings account tax benefits work together and compound over time:
- Deductible or pre-tax contributions: money going in either lowers your federal taxable income as an above-the-line deduction, or is withheld from payroll before tax through a cafeteria plan
- Tax-free growth: interest, dividends, and investment gains inside the account are never taxed as long as they stay in the HSA
- Tax-free qualified distributions: money coming out for qualified medical expenses is not taxed and is not reported as income
HSAs are also portable, which matters for anyone living a mobile life. The account stays with you if you change jobs, change insurers, move between states, or leave the United States entirely.
Unlike a flexible spending account, an HSA is not "use it or lose it". Unused balances roll over year after year, and many expats treat the HSA as a long-term medical savings vehicle rather than a short-term spending account.
Can a US expat still contribute to an HSA after moving abroad?
This is the central question for most expats – and the answer depends on four IRS eligibility tests under IRC § 223(c)(1), not on geography. An expat can contribute to an HSA after moving abroad only if all four conditions are met simultaneously on the first day of each month:
- The account holder is covered by a qualifying high-deductible health plan (HDHP).
- The account holder has no other disqualifying coverage.
- The account holder is not enrolled in Medicare.
- The account holder is not claimable as a dependent on someone else's return.
The practical problem for expats is the first two tests. Many expats lose HSA eligibility after switching to foreign coverage because the new plan often does not satisfy the IRS HDHP rules or the limited coverage exceptions. A plan can have a high deductible by local standards and still end HSA eligibility.
The critical distinction is this: losing contribution eligibility does not mean losing the account. An expat who can no longer contribute can still hold the HSA, invest the existing balance, and spend it on qualified medical expenses anywhere in the world.
What usually disqualifies expats from new HSA contributions
The most common disqualifying scenario is switching from a US HDHP to a local foreign health plan after moving abroad. Even if the foreign plan has a high deductible by local standards, it typically does not meet IRS HDHP requirements.
Other common disqualifiers include:
- Enrolling in Medicare, which disqualifies contributions regardless of other coverage
- Gaining first-dollar coverage through a spouse's plan
- Enrolling in a foreign government health scheme that is not disregarded coverage under IRS rules
- Becoming another person's tax dependent
Common mistake: Many expats assume their international health insurance qualifies as an HDHP because it has a high deductible. A foreign plan can end HSA eligibility on two grounds: it may fail to meet the specific minimum deductible and maximum out-of-pocket thresholds under IRC § 223(c)(2), or it may count as disqualifying other coverage even if the deductible is high.

2026 IRS HSA limits and HDHP thresholds
The IRS adjusts HSA contribution limits and HDHP thresholds annually for inflation. For tax year 2025, the official HSA figures are in Rev. Proc. 2024-25. For 2026, the official inflation-adjusted HSA amounts are in Rev. Proc. 2025-19.
The IRS HSA limits in 2026 represent a meaningful increase from 2025 – self-only contribution limits rose by $100 and family limits by $200.
| Item | 2025 | 2026 |
|---|---|---|
| HSA contribution limit – self-only | $4,300 | $4,400 |
| HSA contribution limit – family | $8,550 | $8,750 |
| Catch-up contribution (age 55+) | $1,000 | $1,000 |
| HDHP minimum deductible – self-only | $1,650 | $1,700 |
| HDHP minimum deductible – family | $3,300 | $3,400 |
| HDHP max out-of-pocket – self-only | $8,300 | $8,500 |
| HDHP max out-of-pocket – family | $16,600 | $17,000 |
An expat who maintains a qualifying US HDHP while living abroad can contribute up to the full annual limit, prorated for the number of months of qualifying coverage during the year.
What medical expenses abroad can you pay with HSA funds?
The IRS HSA eligible expenses list is defined by Publication 502 and IRC § 213(d), and it applies the same way whether you receive care in Boston or in Budapest. What counts is the nature of the service, not the country where it is delivered.
The categories of IRS HSA-covered expenses that travelers and permanent expats use most often cover the eight practical buckets below.
- Doctor and specialist visits
- Hospital inpatient and outpatient care
- Dental cleanings, fillings, and extractions
- Vision exams, glasses, and contact lenses
- Prescribed mental health therapy
- Prescribed physical therapy and rehabilitation
- Maternity, prenatal, and postnatal care
- Medical equipment such as crutches, braces, and blood-pressure monitors
A traveler who sees a local GP for a sinus infection in Lisbon and pays €80 in cash can reimburse that from an HSA. A permanent expat in Mexico who has a root canal done at a local dental clinic for $400 can reimburse that, too.
The list of HSA-allowed expenses per IRS rules does not include:
- General wellness spending is not eligible, and vitamins or supplements are only eligible when recommended as treatment for a specific condition diagnosed by a physician
- Cosmetic procedures that are not medically necessary
- Most nonprescription personal-care items, though over-the-counter drugs and menstrual care products, can be paid for or reimbursed by an HSA
- Gym memberships are usually not eligible, but they can qualify in limited cases when prescribed solely to treat a specific diagnosed disease or to affect a body structure or function
For expats who also itemize US deductions, the same expense cannot be double-counted – if you paid it from an HSA, it cannot also appear on Schedule A as an itemized medical deduction.
Prescription drugs, pharmacies, and foreign-country purchases
Prescription drugs bought abroad can qualify if they are prescribed and otherwise meet the IRS medical-expense rules. Drugs brought into the United States from another country are generally not included unless they are legally imported. Keep the prescription and receipt with your records.
Imported drugs – medications purchased abroad and brought back into the US – are subject to stricter rules and are generally not HSA-eligible. The distinction is between filling a prescription locally while living or traveling abroad versus importing medication into the US.
For each foreign pharmacy purchase, keep the following four records:
- The original prescription
- The pharmacy receipt shows the date, medication name, and amount paid
- A currency conversion record showing the USD equivalent on the date of purchase
- Confirmation that the medication is legally available in both countries
What expenses are not HSA-qualified, even if you live overseas?
Nonqualified HSA distributions are taxable as ordinary income and generally carry an additional 20% tax under IRC § 223(f)(4). The IRS regulations for HSA spending apply equally to expats, and living abroad does not expand what the account will cover.
Generally, you cannot use HSA funds to pay insurance premiums, except for:
- COBRA premiums
- Unemployment-coverage premiums
- Medicare or other health care coverage if you are 65 or older, excluding Medigap
- Long-term care insurance
The 20% additional tax does not apply after age 65, at death, or upon disability – but the distribution remains taxable as ordinary income in those cases.
Is a health savings account taxable?
An HSA is not taxable in the traditional sense – qualified distributions are completely tax-free, and earnings grow tax-free inside the account. The HSA IRS guidelines outline three scenarios where tax treatment differs, depending on your age and how you use the funds.
Case 1 – Qualified distributions: tax-free
When you use HSA funds to pay for IRS-qualified medical expenses, the withdrawal is completely tax-free. This applies whether the expense occurs in the US or abroad, as long as the expense meets IRS criteria under IRS Publication 969. No tax going in, no tax on growth, no tax coming out for qualified expenses.
Case 2 – Nonqualified distributions: taxable plus 20% additional tax
If you withdraw HSA funds for anything other than a qualified medical expense before age 65, the amount is added to your gross income for that year. You will also owe a 20% additional tax on top of regular income tax, unless an exception applies – such as the account holder's death or disability.
Case 3 – Nonqualified distributions after age 65: taxable, penalty-free
Once you reach age 65, the 20% additional tax disappears entirely. Nonqualified distributions are still included in your gross income and taxed as ordinary income – similar to a traditional IRA withdrawal – but without the penalty. Qualified medical expense withdrawals remain tax-free at any age.
Earnings inside the account
Interest, dividends, and investment gains accumulate tax-free while they remain in the HSA. This applies regardless of how long the funds sit there or whether you are living in the US or overseas.

Which tax form reports HSA contributions and distributions?
Form 8889 is the health savings account tax form that reports all HSA activity – contributions, deductions, distributions, and any additional tax calculations. It attaches directly to Form 1040, 1040-SR, or 1040-NR and must be filed for any year you contributed to, received distributions from, or acquired an HSA.
One rule catches many expats off guard: if you or your spouse received an HSA distribution during the year, the HSA IRS form is required even if you would not otherwise have needed to file. A distribution alone triggers the filing obligation.
Recordkeeping for foreign medical expenses paid from an HSA
Keep every receipt for foreign medical expenses paid from your HSA – the IRS can ask you to substantiate any distribution at any time. Each receipt should show the date of service, patient name, provider name, type of service, and amount paid.
For expenses incurred abroad, also retain currency conversion records showing the exchange rate used on the date of payment. You will need to demonstrate that the expense was not reimbursed by insurance or any other source, and that you did not also claim it as an itemized deduction on Schedule A – you cannot use the same expense twice.
What happens to your HSA when you move abroad?
The account remains yours, with all assets, investments, and tax-free growth intact. What changes when you move abroad is contribution eligibility, which typically pauses the day you drop qualifying US HDHP coverage. This is the practical meaning of HSA moving abroad: the account is portable, but new contributions usually stop.
Four scenarios cover most expat situations, and each has a different contribution answer.
- Keeping a US HDHP while abroad. If you remain on a qualifying US HDHP, keep no disqualifying other coverage, and are not on Medicare, you can generally continue to contribute, even while physically living overseas.
- Switching to foreign coverage. If you drop your US HDHP and enroll in a foreign national or private plan that does not meet the HDHP definition in IRC § 223(c)(2), contribution eligibility ends for each month the foreign-only coverage applies.
- Continuing to hold and invest the account. You can keep the HSA open, continue to invest the balance, and spend from it for qualified medical expenses anywhere in the world, even during years when new contributions are not allowed.
- Returning to the US. If you move back and re-enroll in a qualifying HDHP, contribution eligibility restarts for each month you meet all four eligibility tests on the first of the month.
The takeaway that answers what happens to HSA when you leave the country is simple. The IRS treats HSAs as portable property that belongs to the account beneficiary, and nothing about the move itself changes ownership, balance, or the tax-free status of the investment growth. What changes is the monthly eligibility calendar that controls new contributions.
HSA and expat taxes: what this does and does not change on your US return
HSA rules are one piece of a larger filing picture – they do not replace or simplify your broader US tax obligations as an expat. US citizens and permanent residents are taxed on worldwide income regardless of where they live, and that does not change because you have an HSA.
HSA deductions and distributions show up on Form 8889, which attaches to your Form 1040. But the rest of the return still applies. Depending on your situation, you may also need to account for the Foreign Tax Credit, the Foreign Earned Income Exclusion, state tax obligations if your former state still considers you a resident, and other expat-specific reporting requirements.
The HSA does not interact with FEIE or FTC directly – it sits alongside them on the return, not inside them. Maximizing your HSA deduction while also claiming the FEIE or FTC is possible, but the calculations are separate.
FAQ
Yes. IRS eligible HSA expenses follow the same rules abroad as they do in the US – you can use your HSA to pay qualified medical expenses received in any country, as long as the expense would qualify under IRC § 213(d) and Publication 502. The country is not the deciding factor; the nature of the expense is.
Yes. Doctor visits, hospital care, dental work, vision care, mental health treatment, prescription drugs consumed locally, and other qualified categories are all reimbursable from an HSA when received abroad. Keep receipts, exchange-rate records, and proof that insurance did not reimburse the expense.
An HSA is generally not taxable when used as intended. Qualified distributions for medical expenses are tax-free, earnings inside the account grow tax-free, and contributions are deductible or pre-tax. Nonqualified distributions before age 65 are taxable and hit with an additional 20% tax; after age 65, they are taxable but free of the 20% penalty.
Only if you remain covered by a qualifying US HDHP under the IRS guidelines for HSA eligibility – no disqualifying other coverage, not enrolled in Medicare, and not another person's tax dependent. Many expats do not meet all four tests once they switch to foreign health coverage, so new contributions usually stop even though the existing account stays active.
Rarely. The HDHP definition in IRC § 223(c)(2) sets specific US-dollar minimum deductibles and maximum out-of-pocket ceilings, and foreign national and private plans are typically designed around local-currency figures and local benefit structures that do not match the IRS rules. A plan with a high deductible is not automatically an HDHP.
Form 8889. It reports contributions, the HSA deduction, distributions, and the additional tax on nonqualified withdrawals, and it attaches to Form 1040, 1040-SR, or 1040-NR. You must file Form 8889 in any year you or your spouse received an HSA distribution, even if nothing is taxable.
Yes. You can use an HSA in another country by paying out of pocket in local currency and reimbursing yourself from the HSA later. This is the most common way to use an HSA out of the country when a card is declined or not accepted. The tax treatment is identical as long as the expense is qualified and you keep the documentation.
No. The same IRS and HSA rules under IRC § 223 apply to every US taxpayer, whether they live in Ohio or Osaka. What changes for expats is not the rule book but the eligibility picture, because foreign coverage and Medicare enrollment interact with the eligibility tests in ways that pause contribution capacity.
