You're living your dream expat life, when suddenly you get hit with a nasty case of food poisoning. As you're calculating the doctor visit cost in euros, a thought hits you—what about that Health Savings Account you've been contributing to back in the States? Can you actually use it to pay for medical care abroad? And if you're planning to stay overseas long-term, should you even bother keeping it?
If you're a U.S. expat trying to navigate the world of Health Savings Accounts while living abroad, you might be facing a whole new set of questions. While a lot of people may know HSA basics, we all need help when international tax rules get thrown into the mix. So we've put together this guide to help you as an expat navigate the pain of cross-border HSA planning.
What Is a Health Savings Account (HSA)?
Before we dive into the expat-specific complications, let's make sure we're all on the same page about what an HSA actually is and why everyone's been raving about them.
A Health Savings Account is a tax-advantaged savings account that's available to people enrolled in a High Deductible Health Plan (HDHP). Think of it as the triple crown of tax benefits—you get a tax deduction for contributions, the money grows tax-free while it sits in the account, and withdrawals are tax-free when used for qualified medical expenses.
Here's where it gets really interesting for long-term financial planning. After age 65, you can withdraw money from your HSA for any purpose without penalty, though you'll pay ordinary income tax on non-medical withdrawals. This essentially turns your HSA into another retirement account, similar to a traditional IRA, but with the added bonus of tax-free medical withdrawals throughout your lifetime.
For 2025, contribution limits are $4,300 for individuals and $8,550 for families, with an additional $1,000 catch-up contribution allowed for people 55 and older. Unlike Flexible Spending Accounts (FSAs), HSA funds roll over year after year—there's no "use it or lose it" provision that makes you panic-buy contact solution in December.
The catch? You need to be enrolled in a qualifying High Deductible Health Plan to contribute, and that's where things start getting really complicated for expats.
Can U.S. Expats Open or Contribute to an HSA?
Here's where the reality check hits harder than European train ticket prices. The short answer is: it's complicated, and for most expats, the answer is probably no.
To contribute to an HSA, you need to be enrolled in a qualifying High Deductible Health Plan. The problem is that most international health insurance plans—even really good ones—don't meet the IRS requirements for HDHPs. These plans need to meet specific deductible amounts, out-of-pocket maximums, and coverage requirements that are designed around the U.S. healthcare system.
If you're working for a U.S. company abroad and they're providing you with a U.S.-based HDHP that meets all the requirements, you might be able to continue contributing. But this scenario is about as rare as finding good Mexican food in rural Germany. Most expats end up with local health insurance, international health insurance plans, or coverage through their foreign employer—none of which typically qualify as HDHPs under U.S. tax law.
Here's another wrinkle that catches people completely off guard: even if you somehow maintain qualifying HDHP coverage, you also can't have any other health coverage that would disqualify you from HSA contributions. That includes most foreign health insurance plans, which means you'd essentially need to rely solely on your U.S.-based HDHP for all your medical needs while living abroad.
Tax Benefits of an HSA for Expats
Now here's where things get interesting! Even if you can't contribute to your HSA while living abroad, the tax benefits of existing HSA funds remain incredibly attractive for expats—sometimes even more so than for people living in the U.S.
The triple tax advantage we mentioned earlier still applies to expats. Your existing HSA balance continues growing tax-free, and qualified medical withdrawals remain completely tax-free for U.S. tax purposes. This can be particularly valuable if you're living in a high-tax country, as it gives you a source of tax-free income for medical expenses.
But wait, it gets even better! Unlike some other tax-advantaged accounts that can create complications for expats, HSAs generally play well with tax treaties and foreign tax credit calculations. Since qualified HSA withdrawals aren't taxable income to the U.S., they typically don't create additional foreign tax obligations either.
For expats who are subject to both U.S. and foreign taxes, having a source of tax-free funds can be incredibly valuable for managing your overall tax burden. If you need to pay for medical expenses, drawing from your HSA instead of other taxable accounts can help keep your income in lower tax brackets in both countries.
Here's a pro tip that many expats miss: if you're planning to return to the U.S. eventually, keeping your HSA intact while abroad can be a smart long-term strategy. Medical expenses tend to increase as we age, and having a substantial HSA balance when you return can provide valuable tax-free income during retirement.
Limitations of Using an HSA Abroad
Let's face it, this is where HSAs start showing their limitations for expats. While the tax benefits are still attractive, actually using your HSA funds while living abroad comes with some practical challenges that can make you question whether it's worth the hassle.
The biggest limitation is that HSA funds can only be used tax-free for qualified medical expenses as defined by U.S. tax law. While this includes a pretty broad range of medical, dental, and vision expenses, it doesn't necessarily align with how healthcare works in your new country of residence. That alternative medicine treatment that's covered by your local health system? Might not qualify for tax-free HSA treatment under U.S. rules.
Documentation and record-keeping become way more complicated when you're dealing with foreign healthcare providers. You'll need to maintain receipts and documentation that satisfy IRS requirements, which can be challenging when dealing with providers who don't typically work with U.S. patients or understand American tax requirements.
Currency conversion adds another layer of complexity that most people don't think about until tax time. If you're paying for medical expenses in euros or pesos, you'll need to convert those amounts back to U.S. dollars using the appropriate exchange rates for tax reporting purposes. The IRS doesn't care that the exchange rate fluctuated between when you paid the bill and when you file your taxes.
Don't forget about the 20% penalty for non-qualified withdrawals if you're under 65. If you need cash for non-medical expenses and decide to tap your HSA, you'll not only pay income tax on the withdrawal but also face that penalty—which can make accessing these funds pretty expensive for non-medical emergencies.
HSA vs. Other Health Coverage Options for Expats
Local health insurance in your new country might provide better coverage at a lower cost than trying to maintain the U.S.-based coverage just to keep HSA eligibility. Many expat destinations have excellent healthcare systems with much lower costs than the U.S., which can make the tax benefits of an HSA less compelling when you're paying €30 for a doctor visit instead of $300.
International health insurance plans designed for expats often provide more comprehensive coverage for your lifestyle, including coverage in multiple countries and evacuation benefits. These plans typically don't qualify as HDHPs, so you can't contribute to an HSA while enrolled, but they might provide better actual health coverage for your situation.
For digital nomads or people who travel frequently, the flexibility of international health plans often outweighs the tax benefits of maintaining HSA eligibility. Being able to receive covered care in multiple countries without worrying about U.S. tax law definitions of qualified expenses can be worth more than the tax savings.
Here's something many expats don't consider: the opportunity cost of keeping money in an HSA instead of investing it elsewhere. If you're living in a country with low-cost healthcare and don't anticipate large medical expenses, you might be better off investing those funds in accounts that offer more flexibility and potentially higher returns.
Strategic Considerations for Long-Term Expats
If you're planning to be abroad for the long haul, your HSA strategy needs to be part of a bigger picture that considers your entire financial and tax situation. This isn't just about healthcare—it's about optimizing your overall expat financial plan.
For permanent expats who don't plan to return to the U.S., maintaining an HSA might not make as much sense. If you're not going to benefit from the U.S. healthcare system and you're dealing with the hassles of international access and currency conversion, you might be better off liquidating your HSA and investing the funds elsewhere.
But here's where it gets interesting for people who might return to the U.S. eventually. Medical expenses in retirement can be substantial, and having a large HSA balance when you return can provide significant tax-free income. If you're in your 40s or 50s and living abroad temporarily, letting your HSA grow untouched while abroad could be a smart long-term strategy.
Consider the investment options within your HSA as well. Many HSA providers now offer investment options beyond basic savings accounts, allowing your balance to grow more aggressively while you're not actively using it. This can be particularly valuable for younger expats who have decades before they'll need significant medical care.
Don't forget about estate planning considerations either. HSAs pass to surviving spouses tax-free and can be valuable assets to leave to heirs, though non-spouse beneficiaries will need to pay income tax on inherited HSA balances.
The key is being realistic about your timeline and needs. If you're abroad for a few years and planning to return, keeping your HSA makes sense. If you're making a permanent move and integrating into a new country's healthcare system, the complications might outweigh the benefits.
Pro tip: Many long-term expats find that using their HSA as a stealth retirement account works better than trying to use it for current medical expenses. Let it grow tax-free for decades, then use it for medical expenses in retirement—or as additional retirement income after age 65.
Conclusion
Understanding HSAs as an expat doesn't have to feel like you're taking the bar exam in a foreign language. While you likely can't contribute to an HSA while living abroad, existing balances can still provide valuable tax benefits and financial flexibility if you understand how to use them strategically.
The key takeaways? Understand that maintaining HSA eligibility while abroad is challenging for most expats, but existing accounts retain their tax advantages. Consider your long-term plans, actual healthcare needs, and the practical realities of accessing funds internationally when deciding whether to maintain your HSA or explore other options.

FAQs About HSAs for Expats
Can I keep my HSA after moving abroad permanently?
Yes, you can keep your existing HSA account after moving abroad. The account remains yours regardless of where you live, and you can continue to use it for qualified medical expenses. However, you typically cannot make new contributions unless you maintain qualifying U.S.-based High Deductible Health Plan coverage, which is rare for permanent expats.
Are HSA withdrawals taxed overseas?
HSA withdrawals for qualified medical expenses remain tax-free for U.S. tax purposes regardless of where you live. However, your country of residence may have different rules. Some countries might tax HSA withdrawals as income, while others may provide exemptions under tax treaties. You'll need to check the specific tax laws in your country of residence.
Can I pay foreign medical bills with my HSA?
Yes, you can use HSA funds to pay for qualified medical expenses incurred anywhere in the world, as long as the expenses meet IRS criteria for qualified medical expenses. This includes visits to foreign doctors, hospitals, and pharmacies. However, you'll need to maintain proper documentation and convert foreign currency amounts to U.S. dollars for tax reporting.
Do I still qualify for an HSA without a U.S.-based HDHP?
No, you cannot make HSA contributions without being enrolled in a qualifying U.S.-based High Deductible Health Plan. Most international health insurance plans, local foreign health plans, and expat health coverage do not meet the IRS requirements for HDHPs. You can keep your existing HSA, but new contributions typically aren't allowed.
What happens to my HSA if I become a non-resident alien?
If you become a non-resident alien for U.S. tax purposes, you can still maintain your HSA account, but the tax treatment becomes more complex. You may lose some of the tax benefits, and withdrawals might be subject to different tax rules. It's important to consult with a tax professional who understands both U.S. tax law and the tax laws of your new country of residence before making any major decisions.
