Taiwan NHI for Foreigners: Enrolling in National Health Insurance
最終更新日: 2026年5月19日
Taiwan's National Health Insurance (NHI) is a single-payer system that covers roughly 99.9% of the island's 23.56 million residents, and foreigners with a valid Alien Resident Certificate (ARC) are required to join once they meet the eligibility rules. This guide walks through how enrollment works in 2026, what you'll pay, and what to do at the clinic.
Last updated: May 19, 2026
Who has to enroll, and when
NHI is mandatory, not optional, for most foreigners who legally reside in Taiwan. The exact start date depends on your status.
- Legally employed foreigners: enrollment begins on the date of employment. Your employer is responsible for registering you. There is no waiting period.
- ARC holders without an employer (dependents, retirees, Gold Card holders not working for a Taiwan entity, religious workers, etc.): you must enroll after a continuous 6 months of residence in Taiwan. One trip abroad of under 30 days is permitted during that period, but the days spent outside are deducted from the count.
- Spouses, minor children, and disabled adult children of foreign professionals under the Act for the Recruitment and Employment of Foreign Professionals (amended October 25, 2021): enrollment is immediate upon receiving an ARC, with no 6-month wait.
- Foreign newborns with an ARC: enrolled from the date of birth (rule effective December 1, 2017).
- International students: enrolled through the host school once the 6-month residency requirement is met (or immediately, where their dependent status applies).
Coverage ends when your ARC expires or is canceled. If you leave Taiwan and later return, you'll need to re-establish 6 months of residence (with at most one trip under 30 days) before you can re-enroll. A separate rule applies to returning citizens and former residents who have been overseas for more than 4 years: they must wait 6 months after returning and must also pay premiums covering their first 2 years overseas.
How premiums are calculated in 2026
The NHI general premium rate is 5.17% for 2026, unchanged from 2025. Premiums are split between the insured person, the employer, and the government, with the split depending on your insurance category. By law, any increase above 6% would require legislative amendment.
A few key figures for 2026:
- Salary ceiling: NT$175,601 per month. Income above that is not used to calculate premiums.
- Household cap: premiums are charged for at most four members per household (the insured plus three dependents). Additional dependents are covered at no extra cost.
- Average premium: roughly US$42 per month across the insured population.
Common situations for foreigners:
Situation | Premium reference |
|---|---|
Employed (Category 1) | 5.17% of insured salary, split with employer; payroll-deducted |
Self-paid, no employer (Category 6) | Reported at NT$749/month as of 2024, billed quarterly (NT$2,247 every 3 months). Verify the 2026 figure with the NHIA. |
International student | NT$826/month as of 2024–2025, paid via the school |
Dependent of a foreign professional | Covered under the household cap of four members |
If you hold a Gold Card or are self-employed and have no Taiwan employer to register you, your local NHIA office will assign you to Category 6 and bill you directly. Premium tables are updated periodically, so confirm the current self-paid rate at https://www.nhi.gov.tw or by calling the hotline before budgeting.

What you'll actually pay at the clinic or hospital
NHI uses tiered copayments to discourage going straight to large hospitals for minor issues. The figures below are the standard copayments in effect as of 2025 and still apply in 2026.
Outpatient with referral
- Medical center: NT$170
- Regional hospital: NT$100
- District hospital or clinic: NT$50
Outpatient without referral
- Medical center: NT$420
- Regional hospital: NT$240
- District hospital: NT$80
- Clinic: NT$50
Emergency room (effective July 1, 2023)
- Medical center: NT$750
- Regional hospital: NT$400
- District hospital or clinic: NT$150
- Reduced rates (NT$550 / NT$300 / NT$150) apply for near-poor households and people with disability identification.
Medication copayments: the maximum copayment for drugs prescribed at medical centers and regional hospitals was raised from NT$200 to NT$300, also effective July 1, 2023.
Inpatient care: patients are responsible for 5% to 30% of hospitalization costs, depending on the type of ward and length of stay. Annual and per-admission ceilings exist for catastrophic cases.
People with disability identification: outpatient copayments are charged at the clinic rate (NT$50) regardless of which tier of hospital is visited.
The 2023 copayment changes brought in an additional NT$5.27 billion in NHI revenues, and emergency room visits for mild cases (triage levels 4 and 5) fell between 2.27% and 6.43% across hospital tiers, which is what the policy was designed to do.
Document checklist for enrollment
The exact paperwork varies slightly by category, but the core list is:
- Valid passport
- Alien Resident Certificate (ARC) showing at least 6 months of residence, where applicable
- Proof of entry and exit (the NHIA can pull this from immigration records in most cases)
- Employment contract or proof of employment (for Category 1)
- Marriage certificate or birth certificate, translated and authenticated if issued abroad (for dependents)
- School enrollment letter (for international students)
- A Taiwanese bank account or post office account, for direct debit of premiums
- One passport-style photo (for the NHI card itself)
- Local address in Taiwan
Your employer or school handles the submission in most cases. Self-paying foreigners apply in person at a National Health Insurance Administration branch office.
Step-by-step: how to apply
- Confirm your eligibility date. For most ARC holders, count 6 months from your latest entry, subtracting any time you spent abroad. If you're a foreign professional's dependent, you qualify from the day your ARC is issued.
- Gather your documents. Make sure your ARC is current and your local address is correct. NHIA correspondence and your physical NHI card will be mailed there.
- Submit your application.
- If employed: your HR department files on your behalf, usually within a few days of your start date.
- If self-paying: visit the NHIA branch office for the city or county where you live. Bring originals and copies of all documents.
- If a student: the school's international office handles it.
- Receive your temporary certificate. While the physical card is being issued (typically 1–2 weeks for self-applicants, sent by mail), the NHIA can give you a temporary insurance certificate that hospitals and clinics will accept.
- Pay your first premium. Payroll deduction is automatic for employees. Self-paid premiums are billed quarterly and can be paid by direct debit, at convenience stores, at the post office, or through online banking.
- Use your NHI card. Bring it to every medical visit. Pharmacies, dentists, traditional Chinese medicine practitioners, and most clinics swipe it at check-in.

Coverage abroad and special situations
NHI is primarily a domestic system, but it does offer limited reimbursement for emergency or urgent care received outside Taiwan.
- Claims must be filed within 6 months of the date of service.
- Reimbursement is capped at a quarterly ceiling. Using Q4 2019 as an example: NT$971 per outpatient visit, NT$2,937 per ER visit, NT$5,271 per day of hospitalization. The ceilings are updated each quarter.
- You'll need itemized bills, medical records, a diagnosis, and proof of payment, all translated into Chinese or English if originally in another language.
End of the suspension mechanism: as of December 23, 2024, foreigners and citizens can no longer suspend their NHI coverage during long stays abroad. The change was mandated by a 2022 Constitutional Court ruling and is expected to generate roughly NT$2.3 billion in additional annual revenue. In practical terms, if you keep your ARC and household registration active, you keep paying premiums whether you're in Taiwan or not.
Returning after a long absence: if you've been away for more than 4 years, you'll need to live in Taiwan for 6 months before re-enrolling, and you'll be charged premiums covering your first 2 years overseas.
Common pitfalls
- Assuming travel insurance is a substitute. It isn't, once you meet the 6-month threshold or start a Taiwan job. NHI is mandatory, and unpaid premiums accrue.
- Miscounting the 6-month wait. Trips abroad longer than 30 days reset the clock for that interruption, and even short trips have their days deducted. Keep your entry and exit stamps.
- Forgetting that the ARC drives everything. If your ARC lapses, your NHI ends the same day. Renew early.
- Going straight to a medical center for a cold. The copayment difference between a clinic (NT$50) and a medical center without referral (NT$420) is substantial.
- Not updating your address. Premium bills and the physical NHI card are mailed. A missed bill can lead to penalty interest.
- Letting dependents go uninsured. Spouses and children on dependent ARCs are eligible, often under the four-member household cap, meaning extra dependents cost nothing.
- Ignoring the hotline. The NHI Consultation Service Hotline (0800-030-598 from a landline, +886-2-4128-678 from a mobile) has English-speaking staff and can confirm your category and premium.
Frequently asked questions
Can I opt out of NHI if I have private insurance?
No. Once you meet the eligibility criteria, enrollment is mandatory regardless of any private coverage you maintain.
Does NHI cover dental, vision, and traditional Chinese medicine?
Dental and traditional Chinese medicine are covered, with dedicated budget allocations (NT$58.3 billion and NT$36.4 billion respectively in the 2026 budget). Routine vision exams and glasses are generally not covered.
How long does the NHI card take to arrive?
For self-applicants, typically 1–2 weeks by mail. A temporary certificate is issued in the meantime.
What happens if I lose my NHI card?
Apply for a replacement at any NHIA branch office or online. There is a small replacement fee.
Are international students covered for pre-existing conditions?
Yes. NHI does not exclude pre-existing conditions once you are enrolled.
Can I see any doctor I want?
Yes, with no gatekeeper, but the tiered copayment system financially encourages starting at a clinic and being referred upward if needed.
Is the system really that affordable?
The average insured person pays around US$42 per month. The 2026 total NHI budget is NT$988.3 billion (about US$32 billion), with NT$685.3 billion going to hospitals and NT$186.2 billion to primary care clinics.
