Every December, Swiss banks put the same advert up. Last chance to pay into your 3a this year. If you already have one, you know what to do. If you are still deciding whether to open one, this is for you.
Here is how a 3a works, in plain words, with no assumptions about what you already know.
In one line: a 3a is an ordinary savings or investment account with one rule attached, and in exchange for that rule you pay less tax this year.
What it is
You open a 3a account yourself, at a bank or an insurer. You put money into it whenever you like. It sits there and, depending on what you choose, either earns interest or is invested.
That is the whole thing. It is a normal account with two differences.
The rule: you cannot take the money out when you feel like it. It is locked until you are close to retirement, with a few exceptions, and the main one is buying a home.
The reward: in a year when you had earned income that pays AHV contributions, everything you pay in comes off the income you are taxed on for that year, federal, cantonal and communal. Put in 5,000 and the tax office treats you as having earned 5,000 less.
That is the trade. You give up access to the money for a while, and the state stops taxing that part of your salary.
How much you are allowed to pay in
If you have a pension fund at work, which you do if you are employed and earning a normal salary, the limit for 2026 is 7,258 francs a year. That is a ceiling, not a target. Any amount counts.
If you are self-employed with no pension fund, the limit is 20 percent of your net earned income, up to 36,288 francs. Much higher, because you have no employer building a second pot for you.
One thing worth knowing: the limit is per year, and an unused year is gone. You cannot pay in double next year to make up for this one.
What the tax break is worth
The honest answer is that it depends on your canton, your commune, your income and your situation, and those combine differently for every reader. A single figure here would be wrong for almost everyone. What is true in general is simple enough: the more you earn, the more each franc you pay in saves you, because it comes off the top of your income.
Your own tax return software will show you the real answer: enter the amount and look at the difference.
When you get the money back
The normal route: you can have it paid out from five years before your official retirement age, which means from 60 for anyone whose retirement age is 65, and it becomes due at that retirement age. If you are still working, you may leave it where it is for up to five more years.
The exception most people use is your own home. You may take the money early to buy or build a home you will live in yourself, to buy a share of one, or to pay down the mortgage on it. That can be done once every five years.
There are a few other narrow situations where the money comes out early. They are specific and your bank or insurer can tell you in one phone call whether yours is one of them.
And if you are married or in a registered partnership, taking the money out early needs your partner's signature.
What most people find out too late
Most people open one 3a account and pay into it for thirty years. It is tidy, and it can cost them at the end.
When the account is paid out, that payout is taxed on its own, separately from your other income, at a reduced rate.
Where your canton's capital-withdrawal tariff rises with the amount, several smaller accounts emptied in different years can come to less in total than one large one. Whether that holds for you, and whether it is worth the extra accounts, is worth checking while the balance is still small.
One trap to know about: payouts made in the same calendar year are added together and taxed as one, and for a married couple that includes both partners' payouts. So it is the years that have to differ, not only the accounts.
It is worth raising with your provider yourself, because the accounts have to be open before the balance is large.
What thirty-five years actually adds up to
If you started at 30 and paid in the full 7,258 francs every year until 65, you would have put in 254,030 francs at today's limit, which is adjusted from time to time. That is contributions only, before any interest or investment return. Whether the number grows much beyond it depends entirely on what the account is holding, which is why the second point on the list below matters.
It is also the part that is easy to lose sight of, because a 3a account looks small for a very long time and then, quite suddenly, does not.
Where it fits
Your 3a is the third of the three pots that pay for your retirement. The state pension, AHV, comes from the deduction on your payslip. Your pension fund comes from you and your employer together. The 3a is the one that is entirely your choice, and the only one you can decide to change today.
The awkward part is that no one adds the three together for you. That is what SORVA does: you enter what you have once, and it shows you year by year what the three become and when you could stop working, with your 3a in the picture rather than sitting in a forgotten account.

What to check this week
- If you do not have a 3a, the question to settle is whether locking money away until 60 fits your year. The deduction is only worth something if you pay income tax in Switzerland.
- If you have one, check what it holds and whether it is earning interest or invested. Many are sitting in cash without their owner ever choosing that.
- If it is already large, ask about opening a second one for future payments.
- Put a reminder in your calendar for early December. The money has to be in the account before the year ends to count for that year.
Common questions
Is a 3a at a bank better than one at an insurer?
They are two different things, and the law recognises both. A bank 3a is a savings agreement: you decide what to pay in each year, and you can pay nothing at all in a lean year. An insurance 3a is an insurance policy: you agree a premium, usually for many years, and part of each premium buys death or disability cover rather than going into your savings.
The commitment is the part worth settling before you sign. What your income looks like in ten years is not something you know today, and ending a policy early is not the same as pausing a savings plan.
Before signing either one, ask the provider in writing how much of each yearly payment goes into your savings, and what the contract says you would receive if you ended it after three years and after five (the surrender value, in German the Rückkaufswert). Ask the same two questions of the bank, about its fees. Then compare the answers with what you will have paid in by then.
One thing worth knowing: the law lets a bank 3a be combined with a separate risk insurance, so you never have to buy the saving and the cover as one product in order to have both. Bought separately, you see the price of each and can change one without touching the other.
Can I pay in for a year I missed?
Since 2025 there is a limited way to make up missed years, and it has its own conditions. It is a separate subject and we cover it in its own guide.
What happens to my 3a if I die?
It is paid out to the people the law and your contract name, in a set order. If you are unmarried and living with a partner, this is worth checking rather than assuming, because the order does not start with them.
Can I have several 3a accounts?
Yes, and for most people it is the better setup, for the tax reason above.
