Section in charge: National Health Insurance Eligibility Section, Medical Insurance and Pension Division

●What Is Health Insurance?

●National Health Insurance Premiums
National Health Insurance premiums comprise a medical portion, support portion, and Long-Term Care Insurance portion (only for those between 40 and 64 years of age). Each portion is determined by adding together an income-based amount from the previous year and per-capita amount. The latter is calculated based on the number of all enrollees of the National Health Insurance (NHI). To ensure that NHI premiums are calculated correctly, an income tax report for the entire household is necessary. Your cooperation in this matter would be appreciated.
Also, please note that insurance premiums are calculated for the household as a unit, and the head of a household of insured members is responsible for paying insurance premiums. Therefore, please be careful and do not forget to pay your insurance premiums.

●How to Pay the National Health Insurance Premium
Section in charge: Collection Section, Medical Insurance and Pension Division

Insurance premiums can be paid by using the invoice, by direct debit from your financial account, or by deduction from your pension. If you pay premiums by using the invoice or by direct debit, the total amount owed for the entire year will be broken down into ten installments, from June through March of the following year, and will need to be paid by the end of each month.
Insurance premium invoices are sent out twice a year, in June and October. You can pay insurance premiums at financial institutions, such as banks and post offices, at the City Office or Branch Offices, or any city-designated convenience store. If you pay by direct debit, premiums will be paid automatically from your financial account at the end of each month.
If the head of the household is a pension recipient and fulfills the designated requirements, premiums will be deducted from the pension in the months the pension is paid (i.e., six times a year); this excludes those who pay by direct debit. If you have questions about deducting premiums from your pension, please ask the National Health Insurance Eligibility Section.

●Health Insurance Premium Payment Consultation
Section in charge: Payment Consultation Section, Medical Insurance and Pension Division

As a rule, if you are behind in paying your National Health Insurance premiums, you must pay any overdue premiums in one lump sum. However, please take advantage of our consultation services if payment is difficult due to special circumstances.
If you are behind in paying your insurance premiums, you may be issued an eligibility certificate in lieu of the regular health insurance card.

Section in charge: National Health Insurance Benefits Section, Medical Insurance and Pension Division

National Health Insurance is a medical treatment health insurance plan that charges insurance premiums according to your income and covers medical expenses when you are ill or injured. If you show your National Health Insurance card (those 70 years of age or older must also show their Elderly Subsidy Recipient Card) at the hospital reception counter when receiving treatment for an illness or injury, then you only need to pay a portion of the medical expense. National Health Insurance will cover the remaining portion.
There are also benefits for childbirth and funeral expenses. You must file an application to receive these benefits. Please call for more information.
