Pillar 3a: how much tax you actually save

Pillar 3a is seen as the simplest tax-saving lever in Switzerland. That is true, but the saving depends heavily on your income and your canton. This text shows what amount you can expect.

Your saving is the contribution times your marginal tax rate. The marginal rate is the percentage you pay on the top part of your income, and depending on income and place of residence it sits roughly between 15 and 40 percent.

An example: at a marginal rate of 30 percent, a contribution of CHF 7,258 saves around CHF 2,180 in tax. The saving is spread across the federal direct tax and the taxes of canton, municipality and church. The federal share is the same everywhere; the cantonal share makes the biggest difference between locations.

With a pension fund, at most CHF 7,258 per year is deductible in 2026. Without a pension fund, for example as a self-employed person without a second pillar, it is 20 percent of earned income, up to CHF 36,288.

The deduction only applies to the year in which you pay in. You cannot make up for missed years. If you cannot raise the amount in one go, set up a monthly standing order.

On withdrawal a lump-sum withdrawal tax applies. It is calculated separately from your other income, at a reduced rate, and its level differs by canton.

You can break the progression of this tax by holding several pillar 3a accounts and drawing them down over several years. The reason: one large single withdrawal lands in a higher rate than several smaller withdrawals in different tax years. Open additional accounts early enough, because an existing pillar 3a account can no longer be split.

Account or securities in pillar 3a?Abschnitt verlinken

Pillar 3a comes as a pure interest account or as a securities solution with funds. The tax advantage is the same in both cases; it depends only on the contribution, not on the type of investment.

Over a long horizon, broadly diversified securities have historically returned more than an interest account, but the value fluctuates. Watch the total cost of the product, because high fees eat up the return advantage. A pillar 3a solution with an insurance wrapper often ties you to fixed premiums for years, so assess that separately from the pure provision question.

When is pillar 3a less worthwhile?Abschnitt verlinken

If your taxable income is low, your marginal rate is low too and the saving is small. At very low income, for example during education, the contribution brings almost nothing in tax terms.

Caution is also warranted shortly before a planned withdrawal. If you pay in and withdraw in the same year, the tax authorities look closely. And whoever will foreseeably need the money soon for something else ties it up with a pillar 3a contribution until five years before the reference age.

How to proceedAbschnitt verlinken

• Estimate your marginal rate from your canton and your taxable income, then you know the approximate saving per franc paid in.
• Pay in as much as you can spare permanently, up to the maximum for your year.
• Set the standing order to the start of the year rather than December. The money is then invested a year longer.
• Open a second or third pillar 3a account in good time as your balance grows, for a staggered withdrawal.
• Plan the withdrawal across several tax years if several lump-sum payouts could coincide, for example pillar 3a and the pension fund.
