Universal healthcare means everyone in a country can get the care they need without facing financial hardship — a goal the World Health Organization calls universal health coverage. Nearly all high-income countries achieve it, but in very different ways: some fund healthcare through taxes, some through compulsory social insurance, and some by requiring everyone to buy regulated private insurance. For anyone moving abroad, the key questions are how good the system is, how quickly you can join it, and what you will still pay yourself. This guide compares nine of the best universal healthcare systems and explains what each means for newcomers.

Three models of universal healthcare

  • Tax-funded national health services ("Beveridge" model): the UK, Nordic countries, Spain, Italy, Portugal, Australia (partly) and New Zealand fund care mainly through general taxation.
  • Social health insurance ("Bismarck" model): Germany, France, Japan, South Korea and others fund care through compulsory contributions from employers and employees.
  • Regulated private insurance: the Netherlands and Switzerland require everyone to buy a standard package from private insurers that must accept all applicants.

France

France combines compulsory public insurance with widely held complementary policies (mutuelles), so most people pay very little out of pocket. Patients can generally choose doctors, and the system performs well on outcomes such as life expectancy and preventable deaths. Newcomers can usually join the public system (PUMa) after three months of stable residence, via ameli.fr, and should register with a family doctor (médecin traitant) to get full reimbursement.

Japan

Japan's system covers all residents through employer-based or community (National Health Insurance) plans. Prices are set nationally, so costs are predictable, and patients generally pay 30% of costs, less for children and older people, with monthly caps on high costs. Japan has one of the world's highest life expectancies, according to the WHO. Foreign residents staying more than three months must enrol.

Australia

Australia topped the Commonwealth Fund's 2024 comparison of ten high-income health systems. Medicare provides free public hospital care and subsidises GP visits and many specialist services, while the Pharmaceutical Benefits Scheme subsidises medicines. About half the population also buys private insurance. Most temporary visa holders are not eligible for Medicare and must hold private insurance, though reciprocal agreements cover visitors from several countries, including the UK, Ireland and New Zealand.

The Netherlands

Every resident must buy a basic insurance package from a private insurer; the government sets its contents and insurers cannot refuse applicants. In 2026 the average basic premium is around €159 a month and the compulsory annual deductible is €385, with GP visits exempt. Lower earners receive a healthcare allowance. The Netherlands ranked second in the Commonwealth Fund's 2024 comparison.

The United Kingdom

The NHS provides care free at the point of use, funded by taxation. It performs well on protecting people from high costs and on equity, and ranked third in the Commonwealth Fund's 2024 comparison, but waiting times for planned treatment have been a serious challenge in recent years. Most migrants on visas of more than six months pay the Immigration Health Surcharge, which gives them the same access as residents.

Germany

Germany created the world's first national social health insurance in 1883. Most people belong to statutory health insurance funds, with income-related contributions split between employer and employee; higher earners and many self-employed people can opt for private insurance. Coverage is comprehensive, waiting times are generally short, and Germany has more hospital beds per person than most OECD countries, according to OECD health data.

South Korea

South Korea's single National Health Insurance Service covers the entire population and is known for modern hospitals, advanced technology and short waits. Co-payments range from about 20% to 60% depending on the type of facility and service, which encourages people to use local clinics for routine care. Foreign residents staying six months or more are generally enrolled automatically.

Taiwan

Taiwan's National Health Insurance, introduced in 1995, covers more than 99% of the population through a single payer. It is known for low administrative costs, short waits and a smart card that stores patients' medical information. Co-payments are modest. Foreign residents with a resident certificate can join after a waiting period, or immediately if employed.

The Nordic countries

Sweden, Norway, Denmark and Finland run tax-funded, largely regional health systems with low patient fees and annual caps on out-of-pocket costs. Quality is high and access is equitable, although waiting times for non-urgent specialist care can be long. New residents are covered once registered in the national population register.

What about the United States?

The US does not have universal coverage: most people are insured through employers, Medicare (for over-65s), Medicaid (for low-income people) or the Affordable Care Act marketplaces, and millions remain uninsured, according to the US Census Bureau. It spends far more per person than any other country and ranked last in the Commonwealth Fund's 2024 comparison of ten high-income countries.

Spain and Italy: strong systems often overlooked

Spain and Italy both run tax-funded national health services that deliver some of the longest life expectancies in the world at moderate cost. Spain's primary care centres (centros de salud) are widely available, and legal residents who work or pay social security are covered; others can buy into the public system in some regions or use affordable private insurance. Italy's Servizio Sanitario Nazionale covers registered residents, with regional differences in quality, especially between north and south.

What newcomers should check

  • When you can join: some systems cover you from registration, others after a waiting period (for example, three months in France or some Canadian provinces).
  • What it costs: premiums (Netherlands, Switzerland), contributions (Germany, France) or surcharges (UK).
  • What isn't covered: dental care for adults, eye tests and glasses, and some medicines are often only partly covered.
  • Language: find out whether GPs in your area speak your language, or use international clinics in big cities.
  • Temporary visas: many countries require private insurance until you have permanent status.

The bottom line

The "best" universal system depends on your needs. For low out-of-pocket costs and broad choice, France and Germany stand out; for overall performance, Australia and the Netherlands topped the Commonwealth Fund's 2024 comparison; for efficiency and access, Japan, South Korea and Taiwan are models. What they share is that nobody should face financial ruin because they get sick — the principle behind universal health coverage.
