Taiwan’s Constitutional Court has ordered changes to how authorities penalise unpaid National Health Insurance (NHI) premiums, a decision that may affect how other Asian social health insurance systems approach enforcement and contribution compliance.
In a decision handed down on Feb. 7, reported by Taipei Times, the Constitutional Court examined Article 85 of the National Health Insurance Act, which allows regulators to fine policyholders double the amount of unpaid premiums, or triple if the debt is not settled by a specified deadline after the first nonpayment. The justices ruled that using only a multiple of the sum owed as the basis for fines violates constitutional protections for property and due process, including the principle of proportionality in punishment. The court held that the approach does not sufficiently account for the circumstances leading to missed payments.
The case arose from a complaint by a business owner surnamed Chen, who did not pay NHI premiums for some employees and was assessed a triple fine under Article 85. Chen argued that the penalties infringed constitutional provisions on the right to property, due process, and labour protections. After losing in the administrative courts, Chen petitioned the Constitutional Court for relief. Five justices participated in the ruling, while three abstained. The abstaining justices have previously opposed a Constitutional Court decision invalidating Legislative Yuan amendments to the quorum rules for convening the court. They later told a news conference that they did not believe the Constitutional Court could be lawfully convened because the now-invalidated amendments require nine judges to form a quorum. They also maintained that the NHI law already contains a cap on the maximum fines that can be imposed for missed payments and that this limit meets constitutional standards on proportionality.
The court directed that the National Health Insurance Act be amended so that regulators consider relevant factors, such as the reasons for nonpayment, when calculating penalties, instead of applying only a fixed multiple of the unpaid premium. Until the Legislative Yuan completes the amendments, the Ministry of Health and Welfare has been told to follow the spirit of the ruling when enforcing NHI collections and penalties.
Department of Social Insurance Director Chang Yu-hsuan said the ministry will revise the act to comply with the judgment. She added that the ministry would exercise discretion to reduce the amount of fines if the situation warrants it, and said that reliable premium payment remains a cornerstone of the NHI system. For insurers, reinsurers, and health administrators in Asia, the ruling highlights the legal and operational risk of rigid, formula-based sanction regimes that do not allow for individual circumstances, particularly where systems are subject to constitutional review.
Taiwan’s NHI is a mandatory national scheme designed to deliver “universal healthcare coverage, equal access to medical care” on a self-help and mutual assistance basis. It covers both working and non-working populations, including dependents, veterans, the unemployed, women, students, children, and older people who previously fell outside employment‑linked schemes. Participation is compulsory for Republic of China nationals with registered domicile in Taiwan for at least six months and for newborns in Taiwan. Over time, statutory amendments have expanded eligibility to new immigrants, long-term foreign residents, overseas compatriot students, foreign students, and military personnel. Second-generation NHI reforms also extended coverage to inmates in correctional facilities.
Returning nationals who have lived abroad for long periods must either have been insured at some point in the previous two years or re-establish six months of residency to re-enrol. Foreigners must hold an Alien Resident Certificate and reside in Taiwan for at least six consecutive months to join the program. As of the end of December 2024, NHI participants totalled 23,959,972, with 1,019,735 group insurance applicants. For global carriers tracking public-payer exposure, Taiwan’s scheme is a significant single‑payer market in the region.
Since its launch in 1995, NHI has operated under financial self-sufficiency and pay‑as‑you‑go principles. Most income comes from premiums contributed by the insured, employers, and the government, supplemented by overdue premium charges and earmarked revenues from sources such as the Public Welfare Lottery surplus and the tobacco health and welfare surcharge. Demographic aging, higher utilisation, and the introduction of new drugs and technologies have driven expenditure growth beyond premium income. In response, authorities have periodically raised the premium rate and adjusted the payroll bracket table, including the upper and lower limits and the cap on the number of dependents for whom the highest premiums are collected.
Premium calculations for military personnel, civil servants, and teachers have been shifted from basic salary to total compensation. In addition, supplementary premiums are collected from six types of income that were previously excluded from assessment, and a minimum threshold for government contributions has been set. In 2013, second-generation NHI reforms introduced a revenue-expenditure linkage mechanism. The National Health Insurance Committee – composed of representatives of the insured, employers, contracted providers, experts, impartial members, and relevant agencies – reviews the premium rate based on the negotiated total of medical benefit payments each year. The review outcome is submitted to the Ministry of Health and Welfare and then to the Executive Yuan for approval. From Jan. 1, 2021, the general premium rate has been 5.17%, and the supplementary premium rate 2.11%. For insured persons in categories 1 to 3, premiums are calculated as the premium-ratable wage multiplied by the general premium rate. Premiums for categories 4 to 6 are set according to the average premium paid by those in categories 1 to 3.
The ruling on penalties comes as the National Health Insurance Administration (NHIA) is addressing medium- to long‑term sustainability challenges, including chronic disease prevalence and rising healthcare costs. Taiwan has about 8.5 million people with chronic diseases, and the NHIA is targeting the “three highs” (hypertension, hyperglycaemia, and hyperlipidaemia) through lifestyle interventions and the 888 Program for prevention and treatment of these conditions.
Cancer has been the leading cause of death among Taiwan’s top 10 causes for 43 consecutive years. To address treatment costs, the NHIA has established a NT$10 billion New Cancer Drug Fund to reduce the financial burden on patients and families. Treatment guidelines are aligned with international standards, and processes for adding new drugs and medical devices have been accelerated, with evaluation mechanisms aimed at balancing patient access and financial sustainability.
The NHIA also plans to invest in next-generation digital healthcare platforms to upgrade medical information systems, strengthen data protection, and increase transparency in data use, with the aim of supporting health policy development and public administration. For insurance professionals across Asia, the decision underscores that enforcement of social health insurance premiums must be designed within constitutional and legal constraints. Taiwan’s forthcoming amendments to Article 85, together with its financing and benefit measures, are likely to be monitored by markets that are reworking premium collection rules, sanction frameworks, and oversight mechanisms in the context of coverage expansion and fiscal control.
