A contribution to Pillar 3a lets you build up your private retirement savings in a targeted way, and you can deduct the amount from your taxable income. In 2026, you can contribute up to CHF 7'258 if you are affiliated with a pension fund, or up to 20% of your earned income (max. CHF 36'288) if you are not. To ensure the deduction counts for 2026, we recommend making your contribution by mid-December. The money must be credited to your Pillar 3a account by 31 December 2026 at the latest.
