As a US expat living and working in Switzerland, you may be subject to a number of Swiss taxes, including income tax, value-added tax (VAT), social security contributions, and wealth tax. In addition, you may also have ongoing US tax obligations.
In terms of income tax, you will generally be subject to Swiss income tax on your worldwide income if you are considered a tax resident of Switzerland. However, Switzerland and the US have a tax treaty that helps prevent double taxation on your income. Similar protections also exist within Europe. For instance, the
Switzerland–Germany Tax Treaty outlines clear rules on how income and withholding taxes are handled between the two nations. Under this treaty, you may be able to claim a credit for Swiss taxes paid on your US tax return, or you may be exempt from Swiss taxes on certain types of income.
In addition to income tax, you may also be required to register for and collect VAT on behalf of the Swiss government if you have a business in Switzerland, as discussed earlier. If you are an employee in Switzerland, you must also make social security contributions on your salary.
