What is Pillar 3a
Pillar 3a is Switzerland’s tied private pension savings. You pay into a recognised 3a provider (usually a bank or an insurance), and your contributions are tax-deductible.
For employees who are affiliated with a pension fund (2nd pillar), up to CHF 7'258 can be deducted (2025 tax year). Self-employed without a pension fund can deduct up to 20% of earned income, capped at CHF 36'288.
Example
In 2025, you pay CHF 5'000 into your Pillar 3a (e.g., with AXA).
Document
You need the annual contribution statement from your bank/insurance provider.
