Pillar 3a for self-employed: maximum contribution, taxes and pension fund

Self-employed without a pension fund may contribute up to five times more to Pillar 3a than employees. Compando shows the maximum contribution for sole proprietorship, GmbH and secondary self-employment, the tax savings and when a voluntary pension fund is worthwhile.

1. Who can contribute to Pillar 3a as a self-employed person?

In principle, any self-employed person with OASI-liable income may contribute to Pillar 3a. Whether you count as self-employed is decided by the legal form: those who run a sole proprietorship or a partnership (general or limited partnership) count as self-employed. As the owner of a GmbH or AG, by contrast, you draw a salary and count as an employee.

The OASI compensation office assesses self-employment against several criteria. The main indicators are:

  • acting in your own name and on your own account
  • an independent position without instructions from third parties
  • bearing the economic risk

Special rules apply to tax-at-source self-employed and to expats. Those who are self-employed alongside employment and already belong to a pension fund through that job use the regular maximum contribution.

2. How high is the Pillar 3a maximum contribution for the self-employed?

How much you may contribute is set by the pension fund affiliation:

  • Without a pension fund: up to 20 percent of net income from work, at most CHF 36'288 (2026).
  • With a pension fund, also as a GmbH or AG owner: CHF 7'258 (2026), as for employees.

Without a pension fund, you may thus contribute up to five times more than employees. The basis is the OASI-liable net income from work. With fluctuating income, the maximum contribution therefore changes from year to year. With the Pillar 3a calculator you can see how much pension capital builds up over the years.

Good to know: The contribution must be booked by 31 December. Since 2026, retroactive contributions are also possible, for which the smaller amount with a pension fund applies.

When starting self-employment during the year, different rules apply to the two phases: for the time as an employee the amount with a pension fund, for the time afterwards 20 percent from the self-employment. Overall, the maximum of CHF 36'288 remains the ceiling.

3. How much tax can the self-employed save with Pillar 3a?

How much you save depends on income and canton of residence; it quickly amounts to several thousand francs per year:

Net income from work

Contribution (without pension fund)

Tax savings*

CHF 100'000

CHF 20'000

approx. CHF 5'000

CHF 140'000

CHF 28'000

approx. CHF 8'000

CHF 180'000

CHF 36'000

approx. CHF 10'000–12'000

* Guideline values with full deductibility, depending on canton of residence and family status.

Contributions to Pillar 3a reduce taxable income directly. In high-tax cantons such as Geneva or Basel-City, the savings are higher than in Zug or Schwyz. During the term, the pension capital also stays tax-privileged: no wealth tax, no income tax on capital gains, separate taxation only at withdrawal. This way you save taxes over the entire term, not only in the year of contribution.

4. Pillar 3a or pension fund: which makes more sense?

For most self-employed, Pillar 3a is the first choice. A voluntary pension fund is worthwhile above all with a stable high income and when risks such as disability, prolonged illness or death need to be covered. A pure 3a account offers no protection for that. The key question is therefore not the level of the maximum contribution, but which provision solution fits your income in the long term.

Pillar 3a is usually enough if you:

  • have a fluctuating or rather low income,
  • want to stay flexible and not commit for several years,
  • cover risks separately, for example through a Pillar 3a insurance with death and disability protection.

A voluntary pension fund is more worthwhile if you:

  • earn a stable high income,
  • need to protect a financially dependent family or a mortgage,
  • want to benefit from buy-ins for tax purposes and make higher savings contributions.

Important here: A voluntary pension fund affiliation lowers the Pillar 3a deduction from CHF 36'288 to CHF 7'258 and usually ties for several years. A look at the contract term and buy-in strategy is therefore worthwhile before signing.

For many self-employed, a combination makes sense in the end: Pillar 3a for wealth building, plus targeted cover for disability or death.

Which combination of Pillar 3a, voluntary pension fund and risk cover fits your income and family situation is clarified by a consultation with a pension specialist.

5. Conclusion: is Pillar 3a worthwhile for the self-employed?

For the self-employed, Pillar 3a is at the core of retirement provision: without a second pillar, it builds the pension capital and lowers the tax burden at the same time. Those who start early use the tax deduction and compound interest over a longer term.

How much comes out in the end is determined above all by two factors: how you invest and how you withdraw later. A long investment horizon speaks for a higher securities allocation; the key is the right investment strategy. At withdrawal in turn, spreading across multiple accounts with staggered payouts lowers the tax progression.

Against risks such as disability or death, Pillar 3a alone offers no protection. An early review of the pension gap is therefore worthwhile, to arrange additional cover in good time.
