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?
The 3rd pillar comes in two forms. Pillar 3a is tied provision: the state encourages saving with a tax deduction, and in exchange the capital is locked until retirement. Pillar 3b is free provision: no federal deduction, but no constraints either.
The choice is not exclusive. In practice you fill the 3a first each year to capture the deduction, then save in 3b above the cap, or when availability matters more than the tax break.
| Criterion | Pillar 3a (tied) | Pillar 3b (free) |
|---|---|---|
| Deductible from taxable income | Yes, up to the annual cap (CHF 7,258 with a pension fund in 2026) | No at federal level; limited cantonal deductions on some premiums |
| Availability of the capital | Locked; withdrawal at the earliest 5 years before the reference age | Available at any time |
| Early withdrawal | Statutory cases only: main residence, becoming self-employed, leaving Switzerland for good, LPP buy-in, disability | No restriction |
| Taxable wealth | Exempt during the savings phase | Counts towards taxable wealth |
| Taxation on withdrawal | One-off tax, separate from income, at a reduced rate | Depends on the product; no specific withdrawal tax |
The 3a is almost always the one to fill first: the annual deduction is a guaranteed return the 3b cannot offer.
How much to pay in, and when you can take it out
The deductible amount depends on whether you belong to a pension fund: CHF 7,258 in 2026 for an employee who does, more for someone who does not. The capital stays locked until retirement, apart from the statutory early-withdrawal cases.
Those rules, the detailed caps, the tax saving quantified by marginal rate and the exact withdrawal conditions are covered in the dedicated guide: pillar 3a limits and deductions.
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.
Frequently asked questions
- What is the difference between pillar 3a and 3b?
The 3a is tied provision: contributions are deductible from taxable income up to an annual cap, but the capital is locked until retirement apart from statutory cases. The 3b is free provision: no deduction at federal level, but the money stays available at any time and counts towards taxable wealth.
- Is the 3rd pillar compulsory?
No. Unlike the AVS and, for most employees, the 2nd pillar, the 3rd pillar is entirely optional. It is voluntary saving that the state encourages through tax relief in the case of the 3a.
- 3a as a savings account, insurance or securities: which one?
A bank account is flexible but returns little. An insurance solution ties saving to cover and commits you to fixed premiums over many years. A securities solution invests the balance in funds: a higher expected return over the long run, in exchange for fluctuation.
- Can you have more than one 3rd pillar?
Yes, and it is often advisable. Several 3a accounts let you close them in different years and stagger the withdrawals, which lowers the exit tax because its scale is progressive.
