The 3rd pillar (3a) in Switzerland: cap, deduction and withdrawal

By Hippolyte Surer, founder of RetirePlan · Updated June 2026

The 3rd pillar is the optional, individual retirement saving that tops up the AVS and LPP. Pillar 3a (tied) is best known for its tax advantage: contributions are deductible from taxable income. This guide explains the 3a cap, the difference with 3b, the tax at withdrawal and how to fit it into your planning.

3a or 3b: what is the difference?

Pillar 3a is 'tied': it is tax-advantaged, but the capital is locked until retirement (except in specific early-withdrawal cases). Pillar 3b is 'free': no cap and no lock-up, but without the same tax benefit.

For most people, the 3a is the starting point: it combines savings growth with an immediate tax saving.

The tax advantage and the 3a cap

Every franc paid into a 3a is deducted from your taxable income, reducing your tax in the year of the contribution. For 2025, the annual cap is about CHF 7,056 for employees affiliated with a pension fund.

Self-employed people without a 2nd pillar can pay in more: up to 20% of net income, within a limit of about CHF 35,280 (2025). Paying in the maximum each year is one of the simplest and most effective optimisation levers.

When and how to withdraw your 3a

The 3a capital is normally paid out at retirement, but early withdrawal is possible in specific cases: buying your main residence, starting self-employment, leaving Switzerland for good, or buying into the 2nd pillar.

At withdrawal, the capital is taxed once, separately from other income and at a reduced rate. Key tip: holding several 3a accounts lets you stagger withdrawals over several years and reduce the total tax — something RetirePlan optimises for you.

3a savings account, insurance or securities?

A 3a can be held in a savings account (safe, low return), through a life-insurance policy (saving + cover), or in securities / funds (higher long-term return potential, with market risk).

Over a long horizon, a 3a invested in securities has historically returned more than a plain account — but the right choice depends on your horizon and risk tolerance.

The 3rd pillar in your planning

The 3a serves to bridge the gap between your AVS + LPP pensions and your target standard of living. Its impact depends on the amount paid in, the duration and the withdrawal strategy. In planning, it must be considered alongside the other two pillars and your canton's taxation.

RetirePlan folds your 3a into the overall projection: it quantifies the effect of your contributions and optimises the order of withdrawals at retirement.
