Pillar 3a explained: the deduction, the limits and getting the money out
How Pillar 3a works in Switzerland: 3a versus 3b, the 2026 contribution limits, what the deduction is actually worth, when you can withdraw, and why several accounts matter.
In one line: Pillar 3a is voluntary saving that the state subsidises through your tax bill — and the trade for that subsidy is that the money is locked until close to retirement.
The third pillar is private, optional provision. It comes in two forms, and only one of them carries the tax advantage most people are actually after.
3a or 3b: the difference that matters
Pillar 3a is "tied" (gebunden). Contributions are deductible from taxable income, up to an annual limit. In exchange, the capital is locked until retirement age, except for a short list of legally defined early-withdrawal cases.
Pillar 3b is "free". No limit, no lock-up — and no income-tax deduction for contributions. It is ordinary saving and investing, with the tax treatment that normally applies.
For most people the 3a is where to start, because it combines long-term saving with an immediate, certain tax reduction.
The 2026 limits
| Situation | Maximum deductible contribution |
| --- | --- |
| Employed, with a pension fund | CHF 7'258 |
| Self-employed, no pension fund | 20% of net income, capped at CHF 36'288 |
These are annual limits set by the Confederation. Paying in the maximum you are allowed each year is the simplest way to use the advantage in full.
What the deduction is actually worth
Every franc paid into a 3a is subtracted from your taxable income for that year. The saving is therefore the amount contributed multiplied by your marginal tax rate — the rate on your top franc of income, not your average rate.
That has two consequences worth stating plainly:
- The same CHF 7'258 contribution is worth substantially more to a high earner in a high-tax commune than to a modest earner in a low-tax one.
- The benefit is not the full contribution. The money is not tax-free, it is tax-deferred: it is taxed on the way out instead, separately from other income and at a reduced rate. The real gain is the difference between the two.
When you can take the money out
The 3a is normally paid out around retirement — within the window from age 60 to 70. Drawing it triggers a one-off capital-withdrawal tax, charged separately from your other income.
Early withdrawal is possible only in defined cases:
- buying or building your main residence, or repaying a mortgage on it;
- taking up self-employment, or changing self-employed activity;
- leaving Switzerland permanently;
- buying into your pension fund;
- drawing a full disability pension.
Why several accounts, not one
The withdrawal tax is progressive: the larger the amount taken in a single year, the higher the rate applied. Withdrawals made in the same year are added together.
Holding several 3a accounts lets you close them in different calendar years and keep each withdrawal in a lower band. You cannot split one account at withdrawal — an account is closed in full — so the flexibility has to be created years in advance by opening more than one.
Account, insurance or securities
A 3a can be held as a savings account, inside a life-insurance policy, or invested in securities. The choice changes the risk and the expected return, not the tax treatment. A policy also ties the saving to an insurance contract, which is harder to unwind than a bank account if your circumstances change.
Common questions
How much can I pay into Pillar 3a in 2026?
CHF 7'258 if you are employed and belong to a pension fund. Self-employed people without a pension fund can pay in 20% of net income, up to CHF 36'288.
Is Pillar 3a really tax-free?
No — it is tax-deferred. Contributions reduce your taxable income now, and the capital is taxed once when you withdraw it, separately from other income and at a reduced rate.
When can I withdraw my 3a?
Normally between 60 and 70. Earlier only for defined reasons: your main home, starting self-employment, leaving Switzerland for good, a pension-fund buy-in, or a full disability pension.
Why open more than one 3a account?
Because the exit tax is progressive and same-year withdrawals are combined. Several accounts closed in different years keep each withdrawal in a lower band.
