Pillar 3a for expats: eligibility, taxes and departure
New to Switzerland as an expat and unsure whether Pillar 3a is worth it for you? Compando shows who is eligible with a B or C permit, how much tax the contribution saves and what happens to the balance when you leave Switzerland.
1. Can I contribute to Pillar 3a as an expat?
Yes, if you have an OASI-liable income in Switzerland. It is not nationality or the permit that decides, but the income from work. Pillar 3a is therefore open to all working people, whether with a B or C permit, EU/EFTA status or from a third country. Those who live exclusively from wealth or foreign income do not meet the requirement.
How you claim the tax deduction differs by residence status:
- C permit: The deduction runs directly through the ordinary tax return, as for Swiss employees.
- B permit: You pay tax at source and claim the deduction through a subsequent ordinary assessment.
- Cross-border commuters: Contributing is possible; the tax effect follows the double-taxation agreement and the rules of your country of residence.
At the top, the same maximum contribution of CHF 7'258 per year applies to all employees with a pension fund, up to CHF 36'288 for the self-employed without a pension fund.

2. How much tax can I save as an expat with Pillar 3a?
Every contribution lowers your taxable income and with it your taxes. Those who pay tax at source, however, do not get the 3a deduction automatically. From a gross income of CHF 120'000 it is taken into account through the regular tax return; below that, tax-at-source expats claim it with a separate request.
Sample calculation: A 35-year-old software engineer from Lausanne with CHF 130'000 income and a B permit saves around CHF 2'900 in tax per year through the maximum 3a contribution. Over five years he thus saves more than CHF 14'000 in tax.
Especially with a temporary stay, the tax advantage shows early: every contribution year lowers the tax immediately, regardless of how long you stay in Switzerland. How much this comes to at your income and canton of residence is worked out by the tax calculator.
3. What happens to Pillar 3a when I leave Switzerland?
Your 3a balance stays with you and does not lapse on departure. If you leave Switzerland for good, you can have it paid out in cash or carry it forward until retirement. Unlike the mandatory part of the pension fund, there is no restriction on withdrawal by destination country:
Destination on departure | Withdrawal of Pillar 3a |
|---|---|
EU/EFTA | cash withdrawal possible, without restriction |
Third country | cash withdrawal possible, without restriction |
Retirement abroad | regular payout |
If you already live abroad at the time of withdrawal, the pension foundation deducts tax at source at the rate of its domicile canton. Whether your country of residence credits it follows the double-taxation agreement. Which of the two ways is cheaper is decided by the destination country and the timing of your emigration from Switzerland.
Those who leave Switzerland and no longer earn income from work cannot pay in new contributions. The tax savings already gained from the working years, however, remain in place.
4. Conclusion: Is Pillar 3a worth it for expats?
Pillar 3a is worth it as soon as you pay tax in Switzerland. The very first contribution lowers your tax, no matter how long you stay. How strong the effect becomes over time depends on two factors:
- Length of your stay: The longer you stay, the more contribution years add up and the longer the assets grow.
- Level of your income: The higher your income, the greater your annual tax savings.
Pillar 3a thus combines the tax advantage with wealth building. Those who invest the pension money in a securities solution additionally use the compound interest effect and thereby boost the final assets over the years.
