Originally published in 2022; reviewed November 2, 2026. For a broader comparison, see Expat Healthcare Benefits in the US: HSA, FSA & HDHP Guide (2027). The limit below is for 2026; check your employer's plan for the year you are enrolling in.
If you are an expat living in the US, you may be wondering if you can use a flexible spending account (FSA) to cover your healthcare costs. It is an employer benefit that lets you set aside money before taxes for eligible expenses. This introduction covers the basics and some questions to ask before enrolling.
What is an FSA and why should expats care?
An FSA can reduce the cost of healthcare through tax savings. The amount you save depends on your taxes and how much of your contribution you use for eligible expenses. Unused money can be forfeited, so the tax advantage is only part of the decision.
How does it work?
Your employer has to offer the benefit. You elect a contribution, which is deducted from your pay before taxes. A health FSA can reimburse eligible medical expenses for you, your spouse and qualifying dependents. A Dependent Care FSA is a separate benefit with different rules; childcare does not belong in a health FSA.
How to set it up
Ask HR or check your benefits portal for eligibility, enrollment dates and plan terms. You normally make your election during enrollment. Mid-year changes are restricted and depend on the circumstances and your plan.
What expenses does it cover?
Eligible expenses can include doctor visits, prescription drugs, dental and vision care, mental health treatment and eligible over-the-counter medicines. A health FSA cannot pay health insurance premiums. Check a specific expense with your administrator before assuming it qualifies; HealthCare.gov's FSA explanation is a useful starting point.
How to use your FSA funds
Some plans provide a debit card; others reimburse claims. Keep itemized receipts even when you use a card, because your administrator may need documentation to verify eligibility. Using a card does not remove that requirement.
Tips for using FSA wisely
- Enroll when you are eligible. Check when coverage begins and when an expense must be incurred to qualify.
- Understand the use-it-or-lose-it rule. Estimate your eligible spending before choosing a contribution. Your plan may offer a limited carryover or a grace period, but not both for the health FSA. Ask about its deadlines.
- Check the contribution limit. The employee salary-reduction limit for 2026 is $3,400. Your employer may set a lower limit. Do not assume this figure applies to a later plan year.
- Keep documentation. Save receipts and follow the plan's claim procedures.

Quick FAQs
Can I use FSA to pay for my dependent children's medical expenses? Yes, if the expenses and dependents qualify under the plan and tax rules.
How do I know if my employer offers FSA? Check your benefits portal or ask HR.
I am not a US citizen. Can I still use FSA? Citizenship alone is not the deciding factor. Ask your employer whether you meet its eligibility rules.
Can I use FSA for non-medical expenses? A health FSA is for eligible medical expenses. Dependent care uses a separate arrangement.
If your employer offers a High Deductible Health Plan, compare the FSA with a Health Savings Account (HSA). A general-purpose health FSA usually prevents HSA contributions, while certain limited-purpose FSAs can be compatible. The IRS guidance explains the distinction. I also wrote about the pros and cons of HDHPs.
Do your own research before committing money, and check your employer's plan rather than relying on a general introduction.
