- U.S. expats can deduct foreign medical expenses if costs exceed 7.5% of their adjusted gross income.
- Payments must be reported on Schedule A of Form 1040 for the year they were actually paid.
- Foreign currency bills must be converted to U.S. dollars using exchange rates from the specific payment date.
Foreign medical bills can lower a U.S. tax bill for expats, but only when they clear the 7.5% of adjusted gross income floor and are claimed on Schedule A with Form 1040. The deduction applies to unreimbursed care paid overseas, and the rules are the same whether the treatment happened in Boston or Bangkok.
That matters for Americans and green card holders abroad because U.S. tax law still reaches worldwide income. A hospital stay, surgery, dental work, prescription drugs, or medical evacuation premiums can all count if the expense is paid in the tax year and properly documented.
The IRS keeps the core rule unchanged for 2026. Publication 502 still says medical expenses are deductible only above 7.5% of AGI. For readers checking the official guidance, the IRS explains the medical expense rules in Publication 502. The return still runs through Form 1040 and Schedule A, where itemized deductions are reported.
Medical bills abroad that count on a U.S. return
The IRS defines medical care broadly under Internal Revenue Code Section 213. It covers diagnosis, cure, mitigation, treatment, or prevention of disease. Foreign expenses qualify the same way as domestic ones.
That includes payments to doctors, dentists, surgeons, nurses, therapists, acupuncturists, psychiatrists, hospitals, nursing homes, rehab centers, lab fees, X-rays, and ambulance services. Prescription drugs count. So do over-the-counter medicines when they are used to treat illness, not just for general wellness.
Insurance premiums can also qualify when they are paid out of pocket. Health, dental, vision, and long-term care premiums are included. Medical evacuation insurance qualifies when it covers transport and care. Transportation for treatment is deductible too, including mileage at 21 cents per mile in 2026.
Certain costs do not count. Cosmetic procedures are excluded unless they are medically necessary. Life insurance, auto insurance, meals, lodging, and reimbursed bills are also out. If a bill was partly covered by insurance, only the unpaid portion can be claimed.
The timing rule that catches many expats off guard
A deduction belongs to the year the payment was made, not the year the doctor visit happened. That rule matters when overseas treatment is billed in stages.
A $20,000 surgery split across two years is claimed in pieces. If $12,000 was paid in 2026, only that amount belongs on the 2026 return. If the rest is paid in 2027, it waits for the 2027 filing.
The same rule applies to dental work, physical therapy, and hospital bills paid by installment. Expats who move countries during treatment should keep every receipt by payment date. That is the date the IRS cares about.
How the foreign income rules affect the deduction
The medical deduction does not get a special expat bonus. It works under the same federal rules as any other itemized deduction, but the Foreign Earned Income Exclusion can reduce AGI and change the math.
If income is excluded under the FEIE, expenses tied to that excluded income cannot be deducted. That means some premiums and other costs need to be prorated. Foreign tax credits also prevent double counting.
For many filers, the key question is whether itemizing makes sense at all. Standard deductions for the 2026 tax year, filed in 2027, are $15,000 for single filers and $30,000 for married couples filing jointly, with higher amounts for some seniors. If itemized deductions do not beat that number, the medical expense deduction gives no cash benefit.
VisaVerge.com reports that this is where many expats miss savings. They track the expense carefully, but forget the standard deduction comparison and lose the tax benefit.
Turning foreign currency receipts into dollars
Foreign medical bills paid in euros, pesos, yen, or another currency must be converted into U.S. dollars. The best method is the exchange rate on the exact payment date. Treasury data, bank records, and reputable exchange services are all used for support.
Each installment should be converted separately. If the rate changes between payments, each payment keeps its own U.S. dollar value. For small transactions, the Treasury annual average can serve as a fallback when daily rates are not practical.
A €5,000 surgery paid on January 15, 2026, at 1.08 dollars per euro becomes $5,400 on the return. That amount is then tested against the 7.5% AGI floor.
Records the IRS expects to see
The IRS wants substantiation under Section 6001. Good records make the deduction easier to defend and easier to calculate.
Keep these items:
- Itemized invoices showing the date, amount, payee, and service
- Proof of payment, such as bank transfers or card statements
- Insurance explanations of benefits
- Pharmacy records for drug purchases
- Receipts or invoices for transportation costs
- Translations for foreign-language records when needed
If receipts are lost, rebuild the file. Ask the provider for duplicates. Use bank records, billing statements, and medical notes. A signed statement listing the date, amount, purpose, and payee also helps. Digital scans are acceptable, and the IRS prefers records kept for at least three years.
Claiming the deduction on Schedule A
The filing path is simple. Add all qualified medical expenses, subtract 7.5% of adjusted gross income, and report the result on Schedule A. Then compare total itemized deductions with the standard deduction.
The math looks like this:
- AGI of $80,000 gives a threshold of $6,000
- AGI of $150,000 gives a threshold of $11,250
- AGI of $200,000 gives a threshold of $15,000
If someone has $20,000 in qualified medical costs, the deductible amount is $14,000, $8,750, or $5,000 in those examples. The claim is filed with Form 1040 and Schedule A.
Filing timing for Americans abroad
Most expats get an automatic extension to June 15. A further extension to October is available with Form 4868. The tax due date still matters, even when the return is delayed.
Foreign medical deductions do not carry over to another year. Unused expenses vanish if they do not clear the threshold in the year paid. Reimbursements also cut the claim dollar for dollar. A $10,000 bill with $6,000 paid by insurance leaves only $4,000 to test against the floor.
IRS instructions for Form 1040 were updated for the 2025 filing season, and digital records remain the safest approach. That is especially true for expats, who often face audits complicated by foreign language paperwork, moving records, and cross-border payments.
Practical pressure points for overseas taxpayers
The most common mistakes are simple. People forget to include worldwide income in AGI. They claim reimbursed costs. They convert foreign bills using the wrong rate. They also try to deduct expenses paid in a later year.
The deduction is still worth attention. High medical costs abroad can produce real savings, especially when a family has surgery, emergency care, or recurring treatment. The rules are strict, but they are also clear.
Readers who keep receipts, convert payments carefully, and claim only unreimbursed expenses on Schedule A can use the deduction legally and reduce their U.S. tax bill.
