1. About Steuer Law in Sitten, Schweiz

The Swiss tax system operates at three levels: federal, cantonal and municipal. In Sitten (Sion), located in the canton of Valais, cantonal and municipal taxes form a significant portion of the overall tax burden for residents and businesses. Federal taxes, including the direct federal tax and value added tax (VAT), are administered nationwide by the Swiss Federal Tax Administration. Understanding how these layers interact helps you anticipate who administers your taxes and how to plan effectively.

Key concepts you will encounter include tax residency rules, progressive income tax rates, wealth taxation at the cantonal level, property taxes, and VAT obligations for goods and services. Cantonal and municipal taxes can vary considerably within Switzerland, so Sitten residents often need local guidance for filing deadlines, deductions, and appeals.
