How Do Other Countries Pay for Universal Healthcare?

Most countries with universal healthcare pay for it through some combination of taxes and mandatory insurance contributions, though the exact mix varies enormously from one country to the next. Researchers who have tried to classify these systems generally land on at least five distinct types across wealthy nations alone, ranging from fully tax-funded services to employment-based insurance pools to hybrid models that blend elements of several approaches. The differences are not just academic: they shape how much you pay, when you pay it, and whether you even notice you’re paying at all.

The Major Financing Models

There is no single blueprint for universal healthcare. A classification of 30 OECD health systems identified five broad types based on how they regulate, finance, and deliver care: the National Health Service model, National Health Insurance, Social Health Insurance, Etatist Social Health Insurance, and a private-dominated system (essentially the United States as an outlier).¹ A later analysis incorporating primary care orientation and performance management found that these categories can be broken down even further, with at least five distinct clusters emerging from a broader set of indicators.² For practical purposes, though, the financing question boils down to two big buckets: general taxes and mandatory insurance premiums. Countries in the OECD can be grouped by how much they rely on each of these sources to fund their public health guarantees.³

Tax-Funded Systems

Countries like the United Kingdom, Canada, Sweden, Denmark, and Italy fund their healthcare primarily through general taxation. The money comes from income taxes, value-added taxes, corporate taxes, and other government revenues, then gets allocated to the health system through the annual budget. You don’t see a separate healthcare line item on your paycheck. Instead, the cost is baked into the overall tax burden, which means everyone contributes in rough proportion to their income (or spending, in the case of consumption taxes), and coverage is automatic for all residents.

The upside of this approach is simplicity and universality. There is no enrollment process, no eligibility determination, and no risk that someone falls through the cracks because they changed jobs or missed a premium payment. The downside is that the health budget competes directly with every other government priority, from defense to education to infrastructure. When revenues drop during a recession, the health system can face sudden pressure. And because the link between what you pay and what the health system receives is indirect, there can be political tension over how much funding is “enough.”

Thailand offers an instructive example of a middle-income country choosing this path. When it legislated universal coverage in 2002, the government decided on general taxation as the sole financing source, judging that it had the fiscal capacity to support the program and that insurance premiums would be too hard to collect from a population with a large informal workforce.⁴ The system is heavily government-funded, primarily to reduce financial barriers for the poor in a country where a high proportion of people live in poverty.⁵

Social Health Insurance

Germany, France, Japan, the Netherlands, and Belgium take a different route. In these countries, healthcare is financed primarily through mandatory payroll contributions, usually split between employer and employee. If you work, a percentage of your salary goes into a health insurance fund, and your employer matches some or all of it. These funds, often called “sickness funds” or “mutuelles,” operate as nonprofit entities that negotiate with providers on behalf of their members.

This model has deep roots in 19th-century worker solidarity movements, and it carries certain built-in tensions. Payroll taxes act as a form of insurance: your contribution is tied to your earnings, not your health risk, so healthy high earners subsidize sicker or poorer members. But those same payroll taxes can distort the labor market by making it more expensive to hire workers. Research simulating reform options for Germany’s system found that payroll taxes have strong insurance properties but come with real costs in terms of labor supply distortions, while alternative models based on flat premiums increase labor supply but expose workers to more financial risk.⁶ Every country using this model has to navigate that tradeoff.

How Non-Workers Get Covered

An obvious problem with payroll-based systems is that not everyone has a payroll. Children, retirees, unemployed people, full-time students, and people with disabilities don’t earn wages from which to deduct contributions. Countries handle this differently, but the general principle is that the government steps in to pay premiums on behalf of those who cannot pay their own.

In Germany, for instance, pensioners pay reduced contributions from their pension income, and the government covers unemployed people through the social welfare system. In France, universal coverage was extended in 2000 to everyone residing in the country, regardless of employment status, with the government picking up the tab for the poorest residents. Mongolia, when it introduced social health insurance in 1994, made the scheme compulsory for all employees and offered subsidized coverage for vulnerable groups. About 95 percent of the population was enrolled within two years, thanks largely to generous government subsidies for low-income and non-working populations.⁷

Tax-funded systems sidestep this problem entirely, since everyone is covered by virtue of residency. But even in insurance-based systems, the practical reality is that the government ends up subsidizing a substantial share of the population. The distinction between “insurance-funded” and “tax-funded” gets blurry fast once you account for all the public money flowing into insurance schemes on behalf of non-workers.

Single-Payer National Health Insurance

Some countries occupy a middle ground between the tax-funded and social insurance models. In a single-payer national health insurance scheme, the government acts as the sole insurer, collecting funds through taxes or dedicated contributions and paying providers directly. Canada’s Medicare is the most-cited example: each province runs its own single-payer plan, funded by a mix of provincial and federal tax revenues. Taiwan and South Korea also use variations of this approach.

Proponents argue that a single-payer system combines the universality of tax funding with the cost discipline of a dedicated insurance structure. Research comparing financing approaches has found that single-payer systems tend to have relatively lower expenditures while achieving comparable health outcomes to countries with more fragmented insurance markets.⁸ Much of that savings comes from lower administrative costs, which we’ll get to shortly.

Singapore’s Unusual Hybrid

Singapore’s system breaks the mold. It blends compulsory individual savings accounts (called Medisave), a catastrophic insurance plan (MediShield Life), a safety-net fund for the poorest (Medifund), and significant government subsidies for public hospitals. The result is a system that spends only about 4 to 5 percent of GDP on health, with the government’s direct share representing only about a third of that total.⁹

The philosophy is that individuals should bear some financial responsibility for their own healthcare to discourage overuse, while the government provides a backstop for catastrophic costs and subsidizes the poor. In practice, the model works partly because Singapore is wealthy, geographically tiny, and young relative to most rich countries. As its population ages, the government has had to expand coverage through reforms like the Pioneer Generation Package (helping elderly people pay for treatment) and the Community Health Assistance Scheme (subsidizing primary care for lower-income residents).⁹ Singapore’s experience is frequently admired but rarely copied, in part because the conditions that make it work are difficult to replicate elsewhere.

The Role of Private Insurance

Universal healthcare does not mean the death of private insurance. In fact, private insurers play a significant role in many universal systems, but usually in a supplementary or complementary capacity rather than as the primary coverage. France is a good example: the national health insurance system covers about 70 to 80 percent of most healthcare costs, and nearly everyone also carries private complementary insurance to cover the remainder. This supplementary market includes both nonprofit mutual insurers and commercial companies, and the two coexist.¹⁰

Since 2016, French employers have been required to offer private complementary health insurance to all employees. That reform aimed to expand coverage, but it also raised concerns about equity: people outside the workforce, like retirees, students, and the unemployed, don’t benefit from employer-sponsored plans, and the shift in the risk pool could make individual complementary insurance more expensive for those groups.¹¹

In countries like Germany and the Netherlands, higher earners can opt out of the public insurance scheme entirely and buy private coverage instead. This creates a different set of problems. Research on Germany’s opt-out system has found that the public system ends up adversely selected: healthier and wealthier individuals leave for private insurance, while the public system retains a sicker, costlier risk pool.¹² Analysis of both Germany and the Netherlands has found that the ability to choose between public and private coverage creates strong incentives for private insurers to cherry-pick healthy customers, which undermines equity in funding and raises costs for public insurers.¹³

Cost-Sharing and Out-of-Pocket Expenses

Universal coverage does not mean free at the point of use, at least not always. Nearly all high-income countries use some form of cost-sharing, like copayments, coinsurance, or deductibles, to discourage overuse of services. You might pay a few euros per doctor visit in Germany, a small copay for prescriptions in Sweden, or a percentage of specialist fees in France. These amounts are usually modest compared to what uninsured patients face in the U.S., but they add up.¹⁴

The 2008 financial crisis pushed many European countries to increase cost-sharing as a way to manage tightening budgets. Research tracking older Europeans during this period found increases both in the proportion of people who incurred out-of-pocket expenses and in the average size of those expenses. In the Czech Republic, Italy, and Spain, there was a significant rise in people experiencing catastrophic health expenditures, defined as spending more than 30 percent of household income on care. Poorer populations were somewhat protected, reporting lower out-of-pocket costs than wealthier groups, which suggests that existing exemption mechanisms provided at least partial financial protection for the lowest-income residents.¹⁵

Most universal systems cap annual out-of-pocket spending. In Sweden, once you’ve paid a certain amount in doctor visits or prescriptions in a year, further care is free. Japan caps monthly out-of-pocket costs based on income and age. These caps don’t exist in most American insurance plans at the same level, which is one reason medical debt is far more common in the U.S. than in peer countries.

Earmarked Taxes and Sin Taxes

Some countries dedicate specific tax revenues to healthcare rather than drawing from the general budget. Earmarking, which is the practice of assigning revenue from a particular tax to a specific purpose, shows up across the Pacific, Asia, South America, and Africa. Governments earmark funds in different ways: some direct money to health promotion foundations, others subsidize healthier alternatives to taxed products, and still others dedicate revenue to universal health coverage goals. The appeal of earmarking is political as much as financial: it gives the public a traceable link between what they pay and what they get, which can build support for taxes that might otherwise face opposition.¹⁶

Tobacco and alcohol taxes are the most common examples. The Philippines, for instance, dramatically increased tobacco taxes and earmarked the revenue for universal health coverage. Thailand’s health promotion foundation is funded by a surcharge on tobacco and alcohol. These “sin taxes” serve a dual purpose: they generate revenue for the health system while also discouraging consumption of products that drive up health costs. The downside is that earmarked revenue can become a source of bureaucratic conflict between ministries, and the revenue stream shrinks if the tax successfully reduces consumption of the taxed product.

How Countries Keep Costs Under Control

Financing universal healthcare is one challenge; keeping it affordable over time is another. Countries use several tools to restrain spending, and most rely on more than one simultaneously.

Global budgeting is one of the most common. Many OECD countries set an overall spending cap for the health system or for certain sectors within it, like hospital care.¹⁷ Providers work within that budget, and if costs threaten to exceed it, prices or volumes are adjusted. This is a fundamentally different dynamic from the U.S., where prices are largely set by negotiation between each insurer and each provider, with no hard ceiling on aggregate spending.

Fee schedule negotiation is another lever. In France, Germany, and Japan, payers and physician associations engage in structured negotiations to set standardized prices for services. The frequency of updates and the parties involved vary by country, but all three attempt to balance the interests of payers with those of providers within a fee-for-service framework.¹⁸ The result is that the same MRI or hip replacement costs a known, negotiated price everywhere in the country, rather than varying wildly depending on which hospital you walk into.

Health technology assessment also plays a growing role. Before a new drug, device, or procedure is added to the covered benefit package, many countries evaluate whether it works well enough to justify its price. Agencies like the UK’s NICE, France’s HAS, or Germany’s IQWiG make recommendations about coverage and pricing based on evidence of clinical and cost effectiveness. Low- and middle-income countries pursuing universal coverage increasingly need this kind of assessment capacity to decide what their systems can realistically afford to provide.¹⁹

How Doctors Get Paid

The way countries pay their physicians varies and has real consequences for how care is delivered. The main mechanisms are salary (the doctor earns a fixed amount regardless of how many patients are seen), capitation (the doctor receives a set fee per enrolled patient per year), and fee-for-service (the doctor bills for each service performed). Most countries with high universal coverage scores use a blend, often combining capitation with pay-for-performance incentives that reward quality metrics like vaccination rates or chronic disease management.²⁰

Each method has predictable effects. Fee-for-service incentivizes volume: the more you do, the more you earn, which can lead to unnecessary procedures. Pure capitation incentivizes efficiency but can lead to undertreatment if patients with complex needs aren’t compensated differently. A Cochrane review found that evidence on which payment system best achieves policy goals like cost containment or improved quality of care remains limited.²¹ Adjusting capitation by factors like age, sex, and health status can help ensure that doctors aren’t penalized for taking on sicker patients, which is why blended models have become the norm in countries working to expand access.²⁰

Administrative Costs and the Single-Payer Advantage

One area where financing structure makes a measurable difference is administrative overhead. The more payers in a system, the more billing codes, eligibility checks, claims processing, and marketing each insurer and provider has to manage. Systematic reviews have consistently found that multipayer systems carry higher administrative costs than single-payer ones.²² Among compulsory insurance schemes, systems with multiple payers show significantly higher administrative spending than those with a single payer.²³

Modeling of the U.S. system estimated that billing and insurance-related costs could be reduced by roughly a third to a half under a single-payer model, and that certain multipayer reform models could achieve comparable savings depending on how they were designed.²⁴ That doesn’t mean single-payer is the only path to lower overhead, but it does mean that the number of separate insurers in a system has a direct, documentable relationship with how much money gets spent on paperwork rather than care.

Cross-Border Care in the European Union

The European Union presents an unusual wrinkle in universal healthcare financing: citizens of one member state sometimes need care in another. The EU addressed this through regulations coordinating social security systems across borders, aiming to protect people in medical emergencies during travel or work in another member state. Under these rules, migrant workers employed in a country other than their own retain access to healthcare, and planned treatment in another country requires prior authorization from the patient’s home country.²⁵ The European Health Insurance Card, carried by travelers throughout the EU, entitles the holder to emergency treatment on the same terms as a local resident, with costs later reimbursed between governments. It’s an imperfect system, with long reimbursement delays and gaps in coverage for non-emergency care, but it represents a level of cross-border health financing coordination that doesn’t exist anywhere else in the world.

The Aging Population Problem

Every universal system faces the same looming challenge: aging populations. As the share of older residents grows, healthcare demand rises while the working-age tax base that funds the system shrinks. Research on this dynamic has found that population aging moderately increases spending on acute care and strongly increases spending on long-term care. The interaction between aging and medical technology amplifies the effect: new treatments tend to be used most intensively for older patients, meaning that an aging population and advancing technology reinforce each other’s upward pressure on costs.²⁶

Countries are responding in different ways. Japan, which has the oldest population among major economies, introduced a dedicated insurance scheme for people aged 75 and older, funded partly by premiums from enrollees and partly by cross-subsidies from the insurance plans covering younger workers. Germany created a separate mandatory long-term care insurance in the 1990s. Singapore, as mentioned earlier, expanded subsidies for its elderly through the Pioneer Generation Package. There is no consensus on the best approach, but every country with universal coverage is grappling with the same fundamental arithmetic: more people needing more care, funded by a relatively shrinking pool of working-age contributors.
