Pillar 3a calculator 2026
Work out how much your pillar 3a contribution saves you in tax — by canton, income and marital status, with the official 2026 schedules.
| Tax without 3a contribution | CHF 15'888.15 |
| Tax with a contribution of CHF 7'258 | CHF 14'000.37 |
| Saving (≈ 26.0% of the contribution) | CHF 1'887.78 |
Canton of Zurich (capital), direct federal tax included, excluding church tax. Taxable income before contribution: CHF 100'000.
Why pillar 3a is the simplest tax deduction
Pillar 3a is the private, tax-privileged pension — and for most working people the most effective deduction you can get without much effort. Every franc paid in immediately lowers taxable income, and the balance is exempt from wealth and income tax on returns for the whole term. Anyone who wants to know whether a contribution pays off and how much it concretely brings needs a figure, not a gut feeling: that is exactly what the calculator delivers — for your canton, income and marital status.
How the calculation works
Your 3a contribution is deducted from taxable income. We calculate your income tax (canton + capital municipality + direct federal tax) once without and once with the deduction — the difference is your tax saving. The basis: the cantonal 2026 schedules and multipliers from the FTA tax data.
As a formula: saving = tax(income) − tax(income − contribution). Because the contribution cuts away your top — most heavily taxed — francs of income, the saving equals your marginal tax rate applied to the amount paid in: the higher your income and progression, the bigger the effect.
Worked example step by step
Taxable income CHF 100'000, single, canton of Zurich, contribution CHF 7'258:
- Tax without contribution: CHF 15'888
- Tax with contribution: CHF 14'000
- Saving: about CHF 1'888 per year
Over 30-plus working years this effect repeats year after year — the tax saving alone adds up to a five-figure amount, on top of the saved and compounded capital itself.
Deciding smartly: what to watch for
- Max out first: the deduction only works up to the annual maximum (CHF 7'258 with a pension fund). If you can, pay in early in the year — the money is then invested longer.
- Several accounts for a staggered withdrawal: at payout the capital is taxed separately. Holding several accounts and withdrawing them in different years breaks the progression — seestaggered pillar 3a withdrawal.
- 3a or 3b? Restricted pillar 3a brings the deduction, flexible pillar 3b stays available any time. What suits you: pillar 3a vs 3b.
- Limits of the calculation: we use the capital's multiplier (your municipality can differ) and exclude church tax; the later capital-benefits tax on withdrawal is not part of this saving calculation.
Frequently asked questions
What is the maximum pillar 3a contribution in 2026?
Employed people who belong to a pension fund can pay in at most CHF 7'258 in 2026. Without a pension fund (self-employed), it is 20% of earned income, up to a maximum of CHF 36'288. The amounts are set each year by the Federal Social Insurance Office (FSIO).
How much tax can I save with pillar 3a?
The contribution is fully deducted from taxable income — the saving equals your marginal rate. Depending on canton and income, that is typically 20 to 40% of the contribution: for the maximum amount, roughly CHF 1'500 to 2'900 per year. The calculator above shows your exact figure.
Is it worth contributing even on a modest income?
The tax effect is smaller for low incomes, because the marginal rate is lower. Pillar 3a nonetheless remains a sensible retirement-savings instrument, and every contribution reduces tax at least a little. Run your own figures above.
Is the capital taxed on withdrawal?
Yes, on withdrawal the pillar 3a capital is taxed separately from the rest of your income, at a reduced rate (capital-benefits tax, varying by canton). The saving during the contribution years generally clearly exceeds this exit tax. Staggering withdrawals over several years reduces it further.
