Is Pillar 3a worth it in Switzerland?

For most people, yes. Pillar 3a is Switzerland's voluntary retirement savings scheme and one of the most effective ways to reduce your taxable income. Every eligible contribution can lower your income tax for that year, while your savings grow until retirement. The maximum annual contribution is set by federal law and updated periodically, making Pillar 3a a valuable tool for both tax planning and long-term retirement savings.
