the-income-tax system-in-Switzerland

Taxes are an integral part of modern economies that enable governments to function, public infrastructure to be built, and key institutions to provide basic services such as education, medical care, and security. All of these benefits make taxes a civil obligation that everyone needs to fulfill at the best of their abilities. 

In Switzerland, income tax is seen as a responsibility and a morally obliging contribution upon Swiss citizens of all classes. Accordingly Swiss government takes income tax very seriously, and citizens are legally required to declare all of their taxable income.

The Income Tax System in Switzerland

The income tax system in Switzerland can be hard to get your head around, as the amount you pay depends on where you live in the country. The Swiss tax system follows a federalist structure, where the government levies a direct income tax. The individual cantons and 2,250 municipalities levy an additional tax on income and capital.

Switzerland’s income tax laws are based on the principle that a family’s income represents an economic unit. So, only one tax return is necessary for each family, and the income and wealth of both partners are combined and filed together. If any children under the age of 18 earn an income, they must declare it in their parents’ tax return.  

Self-employed workers in Switzerland have to submit a tax return every year, but employees are usually taxed through a pay-as-you-earn (PAYE) system arranged by their employer.

What is income tax? 

Income tax is a type of tax that the government enforces on a person’s or business’s registered income. This type of tax is usually collected annually, so at the end of a fiscal year, people are obliged to declare their annual income, after which they are taxed at either a fixed or progressive rate.

Who pays income tax in Switzerland?

Tax regulations may vary between the different cantons; however, anyone living in Switzerland for no more than 183 days a year can be exempt from income tax.

Taxable Income in Switzerland

Taxable income is the sum total of the wealth that is taxed for a taxable entity. However, not all of the income of a person is taxed. Accordingly, several expenses are deducted from income tax. Some of these deductions include employment expenses, business expenses, and family expenses (such as day-care expenses and spouse and child alimony).

Taxes on income/salary in Switzerland
