Choice of canton and municipality

In Switzerland, the tax burden can vary significantly depending on the canton, municipality and your personal situation. Unlike other countries where taxation is mainly national, Switzerland operates a federal system: tax is levied at three levels - federal, cantonal and municipal. This structure leads to major differences from one place to another.

This is not just a theoretical issue. Your choice of tax domicile can have a real impact on your annual budget, whether in terms of income, wealth or even inheritance plans. In this article, we explain why and how your choice of canton affects your taxes, with some concrete examples to help you understand the real impact.

A fragmented tax system: three levels of taxation

The first level is Direct Federal Tax (DFT), which is applied uniformly throughout the country. It remains relatively moderate. By contrast, cantonal and communal taxes - set freely by each canton and commune - vary widely. Rates, scales, possible deductions and thresholds vary from one canton to another, and even from one commune to another within the same canton.

This is why two people living just a few kilometres apart can have very different tax situations, despite having similar incomes and assets.

Concrete example: a single person with no children and an annual income of CHF 120,000

Let's take the example of a single employee with no children and a gross annual income of CHF 120,000. His overall annual tax burden (including federal, cantonal and municipal taxes) varies greatly depending on the canton:

  • Zug (municipality of Baar): around CHF 10,000 in taxes

  • Schwyz (municipality of Freienbach): around CHF 11,000

  • Vaud (Lausanne): around CHF 19,500

  • Neuchâtel: approx. CHF 22,000

  • Jura (Delémont): approx. CHF 23,500

Between the cantons of Zug and Jura, the difference is more than CHF 13,000 per year, or more than CHF 1,000 per month. This represents a significant proportion of disposable income.

Example of a family: married couple, two children, income of CHF 180,000

Families generally benefit from specific tax deductions: dependent children, childcare costs, post-compulsory education, etc. Here are the estimates for a married couple with two children:

  • Zug (municipality of Steinhausen): around CHF 6,500 in tax

  • Fribourg (city of Fribourg): approx. CHF 12,000

  • Geneva (City of Geneva): around CHF 18,000

Once again, for the same income, a couple living in Zug will pay almost three times less tax than in Geneva.

Ranking of cantons by tax level

The most tax-efficient cantons for individuals are :

  • Zug: often cited as the most tax-friendly canton, with very low rates on income and wealth.

  • Schwyz: very low tax rates, particularly for high earners.

  • Nidwalden, Obwalden and Appenzell Innerrhoden: low rates, good tax appeal.

Conversely, the cantons with the highest tax rates are :

  • Jura: high income and wealth tax.

  • Neuchâtel: historically high taxation, although efforts to reform are under way.

  • Geneva: high taxation, partly offset by higher salaries.

Taxation of wealth: differences that are sometimes underestimated

Switzerland applies an annual tax on net wealth, which is rare in Europe. The rate and exemption threshold vary from canton to canton. Here's an example:

A taxpayer with CHF 2 million in net assets (real estate, securities, etc.) :

  • Will pay around CHF 3,000 in Zug

  • Will pay more than CHF 15,000 in the canton of Vaud

This represents a difference of CHF 12,000 each year. This tax burden on wealth should therefore be anticipated, especially for wealthy individuals or property owners.

Inheritance and gift tax: a subject often overlooked

The rules on inheritance and gift tax vary from canton to canton. In some cantons, direct heirs (spouses, children) are exempt, but in others, significant taxes may apply to certain heirs.

For example:

  • In the canton of Vaud, children are exempt, but brothers, sisters, nephews and friends can be taxed at rates of up to 50%.

  • In the canton of Zug, inheritances are generally exempt, even for non-direct heirs.

Before making a donation or preparing an inheritance, it is important to analyse the impact of the canton.

Corporate taxation: a strategic issue for companies

Differences in corporate tax rates are also significant. The overall tax rate on profits (federal, cantonal and municipal tax combined) is :

  • 11.8% in Zug

  • 12.3% in Lucerne

  • 13.8% in the canton of Vaud

  • 14% in Geneva

This explains why many national and international companies choose to locate their headquarters in low-tax cantons.

Changing canton to pay less tax? A strategy to be considered with caution

Some people consider moving to another canton to optimise their tax burden. This may make sense in some cases, but the decision should not be based on tax alone. You should also take into account

  • the cost of accommodation

  • Distance to work

  • Quality of public services (schools, transport, health)

  • Social assistance and subsidies (particularly for health insurance premiums)

  • Social and cultural life and general quality of life

A tax break does not always make up for a more difficult day-to-day life or higher hidden costs.

What about cross-border commuters? A special situation

Taxpayers who live in Switzerland and work abroad (or vice versa) are subject to specific rules under international tax treaties. For example, cross-border commuters from Geneva or Vaud working in France have to comply with specific tax rules. Here again, the canton of residence plays a central role in tax allocation.

Conclusion: optimisation needs to be adapted on a case-by-case basis

The choice of canton is a key element in tax management. For the same income, two taxpayers may pay radically different taxes depending on where they live. However, a personalised analysis is needed to make an informed decision. It's not just a question of tax rates, but of a whole range of parameters: family, assets, business, quality of life, mobility, etc.

Understanding the cantonal differences can help you avoid unpleasant surprises and consider practical solutions for reducing your tax burden in a legal and strategic way.
