3rd Pillar Simulator (cross-border guide)
Pillar 3a for cross-border workers: tax deductions, 2026 limits, best providers and retirement savings strategies.
By Frontaliere Ticino Editorial Team
The third pillar 3a simulator calculates accumulated capital and future pension based on annual contributions, duration, expected return, and withdrawal tax, showing the fiscal advantage over non-tax-advantaged investments.
Since 2025, the annual contribution ceiling is CHF 7,258 for people affiliated with an occupational pension scheme. This ceiling does not mean that a contribution automatically reduces Swiss withholding tax; the tax treatment depends on the person’s assessment and applicable rules.
The simulator also compares scenarios with different time horizons and returns, letting you visualise the effect of compound interest and tax relief over the long term.
Fiscal cross-border workers covered by the 2020 Italy–Switzerland agreement cannot request supplementary ordinary taxation (TOU). Do not assume that a pillar 3a contribution is deductible from source tax; confirm the treatment that applies to your tax status with the competent authority.

Compare bank and insurance products using their fees, terms, investment choices, guarantees, and access conditions. The suitable option depends on the contract and your circumstances.
