Tax Deduction with Pillar 3a

How does the tax deduction work with pillar 3a?

You can deduct contributions to pillar 3a from your taxable income up to an annual maximum. This lowers your taxable income and therefore your tax burden. On withdrawal, the capital is taxed separately.

What the calculator shows

  • Tax savings: in total and per year.
  • Capital: deposits, interest or performance, and net capital.
  • Tax on withdrawal: the tax due when the 3a capital is withdrawn.
  • Product: choose between a 3a account, a 3a policy or a 3a fund policy.

The "Staggering" tab shows staggered withdrawal.

Assumptions: 19 years, CHF 7'258 per year, with a pension fund, 3a account with an interest rate of 0.70%, single, no religious denomination, residing in 8000 Zurich, year of birth 1980. Only gross income changes. The figures come from the calculator above. The interest rate is assumed and is not a forecast.

Gross income CHF 60'000

  • Total tax savings: CHF 21'926
  • Tax savings per year: CHF 1'154

Gross income CHF 100'000

Reading the result correctly

Tax savings depend on your income: in the example they range from CHF 1'154 per year (gross income CHF 60'000) to CHF 2'173 per year (CHF 150'000).

The same in all three examples: deposits CHF 137'902, interest and performance CHF 10'071, tax on withdrawal CHF 7'699 and net capital CHF 140'274.

The calculator works with fixed assumptions. In practice, income, tax rates and laws change. More on pillar 3a and on taxation on capital withdrawal.

That depends on income, place of residence and contribution. In the example above it is CHF 1'154 to CHF 2'173 per year with a contribution of CHF 7'258. For your situation, use the calculator.

Yes. You declare contributions to pillar 3a in your tax return so that they are deducted from taxable income. Your provider issues a certificate for this.

What matters is that the contribution is credited to the 3a account in the relevant tax year. Pay in in good time before the end of the year.

On withdrawal, the 3a capital is taxed separately. In the example, the calculator shows CHF 7'699. The amount depends on canton, marital status and capital amount.
