Pillar 3a (gebundene Vorsorge / prévoyance liée) is Switzerland's tax-favored private retirement saving. 2025-26 federal limits: CHF 7,258 if you have a second pillar (employees), or 20% of net income capped CHF 36,288 for self-employed without 2nd pillar. Withdrawals taxed separately at reduced rate.
Why Pillar 3a Is the Best Swiss Tax Move
Triple benefit: 1) Contribution reduces taxable income — saving cantonal + federal tax at your marginal rate (often 25-40%). 2) Growth tax-free during accumulation. 3) Withdrawal taxed separately at favorable lump-sum rate (~5-10%, not marginal income rate).
Maximum Contribution Rules
Employed with 2nd pillar (BVG): CHF 7,258/yr (2025-26). Self-employed without 2nd pillar: 20% of net income, max CHF 36,288/yr. 2027 limits not yet published — typically index +1-2% per year. Check ESTV announcements late 2026.
Cantonal Tax Saving Differences
Highest marginal: Geneva, Vaud (35-40% combined). Mid: Zurich, Basel (25-32%). Lowest: Zug, Schwyz, Nidwalden (15-20%). Same CHF 7,258 deduction can save anywhere from CHF 1,500 (Zug) to CHF 3,000 (Geneva).
Multiple 3a Accounts Strategy
Spread your 3a across 2-5 accounts (at different banks/insurers). At retirement, draw each in different tax years to stay in lower marginal lump-sum brackets. Most cantons tax lump-sum withdrawals on a sliding scale — chunking reduces total tax 20-40%.
