Swiss Mandatory Costs Rise – Primarily Due to Premiums

The Most Important Figure: 30.5 Percent

How much a Swiss household pays to the state and mandatory systems cannot be answered with a single figure. The best official approximation comes from the Household Budget Survey of the Federal Statistical Office (BFS). In 2023, an average private household had a gross monthly income of 10,341 Swiss francs. Of this, 3,154 Swiss francs went to mandatory transfers: 1,245 Swiss francs for taxes, 1,062 Swiss francs for social security contributions, 689 Swiss francs for mandatory basic health insurance, and 159 Swiss francs for regular transfers to other households. Together, this amounted to 30.5 percent of the gross income.

However, this figure does not describe a "typical" single person or a family of four. The average household comprised 2.07 people; 61 percent of households had less than the average disposable income. Furthermore, the annual sample of 3038 households was too small for robust detailed values for every household type. A precise profile calculation must therefore disclose the assumptions it uses.

Two Comparable Model Households

JournalPlus calculates with the average Swiss salary of 100,715 Swiss francs estimated by the OECD for 2025. For income tax, the OECD uses the Canton and City of Zurich. This creates an internationally comparable model. However, it is not a nationwide tax average: place of residence, denomination, deductions, income distribution, and age significantly alter the result.

For a single employee without children, the burden directly borne by the salary from income tax and state social contributions, according to the OECD, is 18.1 percent, or approximately 18,229 Swiss francs. Additionally, the model includes 7.83 percent, or 7,886 Swiss francs, for the pension fund and the average adult premium for 2026 of 5,584 Swiss francs. This means 31,699 Swiss francs, or 31.5 percent of the gross salary, are committed before consumption taxes apply.

For a married single-earner couple with two children, the OECD burden after taxes, social contributions, and family benefits decreases to 5.1 percent, or approximately 5,136 Swiss francs. Adding the same pension fund assumption and the average premiums for two adults and two children results in 27,129 Swiss francs, or 26.9 percent of the gross salary. Basic health insurance alone costs 14,107 Swiss francs per year in this model – before any potential individual premium reduction.

Families Pay Differently, Not Simply Less

The difference compared to a single person arises primarily from child deductions, the more favorable family tariff, and family allowances. At the same time, a family pays four per capita premiums. Whether they are actually better off thus strongly depends on the canton, the age of the children, a second income, and premium reductions. The calculation above intentionally depicts a single-earner couple; a dual-earner couple may face different tax burdens.

The pension fund should also not be misunderstood as a tax. It is mandatory provision and generally remains the assets of the insured person. The basic health insurance premium is also not state revenue: it flows to regulated but legally independent health insurers. Both payments are mandatory for the household budget; for the question of what "the state receives", they must be reported separately.
