Pillar 3a for Married Couples: How to Optimise Your Joint Retirement Savings

By Thierry Borgeat, CFA & Co-Founder · Reviewed by Patrick Rissi, CFA and Florian Jauch, CFA · Updated May 2026 · 11 minute read

As a married couple, you have a double lever in Pillar 3a — and a double trap. The lever: each partner contributes separately, totaling CHF 14'516 per year (2026). The trap: all your withdrawals in the same year are combined and taxed jointly at the progressive rate. Those who ignore this quickly forfeit CHF 10'000-25'000 at withdrawal. Those who plan extract maximum value. This article shows you step by step how to coordinate your Pillar 3a as a couple — from the savings phase to the final withdrawal, with worked examples for dual-earners, part-time couples, and self-employment scenarios.

Why couples must think differently than singles

The Swiss tax system treats married couples as a single economic unit. This has consequences in both directions: you benefit from the double deduction during the contribution phase — but you suffer from the combination rule at withdrawal. Concretely:

The table shows the tension: higher potential, but also higher complexity. Without planning, you forfeit both. With planning, you double the upside.

The contribution phase: double tax lever

Couples building an optimal 3a strategy start with maximum contributions by both partners. Both accounts — separately, in each name, with their respective social security numbers.

For a typical Swiss dual-earner couple with combined gross income of CHF 200'000, this produces:

Over 30 years of savings, the additional tax savings amount to around CHF 60'000 — purely through consistent double contributions. On top of that come additional returns on the contributed capital (at 4% return, another CHF 250'000+ in wealth accumulation).

The 5-account rule for couples

Each partner should have their own 5 accounts. Not 5 joint accounts — those don't exist in Pillar 3a. Pillar 3a is always individual, tied to the respective AHV number.

This gives you as a couple potentially 10 separate 3a accounts — 5 for Partner A, 5 for Partner B. If you stagger these optimally in the withdrawal phase, you can theoretically distribute withdrawals across 10 tax years.

When one partner isn't working

Pillar 3a is only available to persons with AHV-subject earned income. Those who don't receive a salary — for example as a pure homemaker, or during long-term unemployment — cannot contribute to Pillar 3a.

This is a political weakness of the Swiss system and one of the biggest reasons for the pension gap among women. Anyone not working for 10 years (e.g. due to childcare) misses out on CHF 72'580 of possible contributions plus compound interest. Over a lifetime, that quickly amounts to several CHF 100'000 less in retirement assets.

What counts as earned income?

• Main employment (including part-time from 1 CHF annual salary)
• Sideline income (self-employed or salaried)
• Substitute income: per-diem and sickness benefits, IV per-diem benefits (but not AHV pension)
• Self-employment: AHV-subject fees

What does NOT count as earned income?

• Investment income (dividends, interest, rent)
• Maintenance payments from a partner
• Family and child benefits alone
• Social assistance or AHV pension

Strategies for asymmetric couples

1. Main earner maxes out 3a: higher tax progression = greater lever
2. Part-time partner contributes the maximum possible: every franc counts
3. For main income > CHF 150'000: review additional PK buy-ins (higher tax effect than 3a)
4. For self-employment of one partner: use the big 3a deduction up to CHF 36'288

The withdrawal strategy: alternating years

This is where the biggest lever of married-couple optimisation lies — and at the same time the most expensive mistake. All retirement withdrawals from both partners in the same tax year are added together. Those who ignore this quickly pay CHF 10'000 too much in tax.

The solution: alternating withdrawal years

The principle is simple: in each tax year, only one partner withdraws retirement assets. This way each withdrawal stays in the lowest progression bracket on its own.

In this plan, Partner A withdraws in even age years (60, 62, 64, 65), Partner B in odd ones (61, 63, 65). Both finalise their withdrawal in retirement year 65 — but if both are the same age, they collide there again.

The refinement: PK in different years

If both partners are the same age and both want to withdraw their pension fund as capital, there are two ways:

• Early retirement for one partner: Partner A retires at 64 (PK withdrawal age 64), Partner B at 65
• Deferred withdrawal: one partner defers PK withdrawal — if they continue working, this can extend to age 70

Even with just one year of difference, the combination rule is avoided — tax savings can be CHF 10'000-30'000 depending on withdrawal amount.

Coordinating PK and 3a withdrawals

Your coordination goes beyond just the 3a. The same combination rule applies to the pension fund: PK capital + 3a + vested benefits of both partners in the same year = one single taxable pot.

A typical Swiss dual-earner couple with PK capital withdrawal at retirement has:

• Partner A: PK capital CHF 400'000 + 3a 5× CHF 100'000 = CHF 900'000
• Partner B: PK capital CHF 300'000 + 3a 5× CHF 80'000 = CHF 700'000
• Combined: CHF 1'600'000 retirement capital

If both withdraw everything in the same year: CHF 1'600'000 as one withdrawal — tax in Zürich approx. CHF 175'000. With optimal staggering over 10 tax years: approx. CHF 95'000. Saving: CHF 80'000.

Three coordination rules

1. PK and 3a never in the same year for the same person. 3a withdrawal either one year before or after PK withdrawal.
2. Never both PK withdrawals in the same year. Partner A's PK withdrawal and Partner B's PK withdrawal in different tax years.
3. Never both 3a withdrawals in the same year. Alternating years for the staggered 3a accounts.

Worked example: The Meier couple in Zürich

Andreas and Sabine Meier are both 60, live in the city of Zürich. Andreas has 4 separate 3a accounts totaling CHF 320'000, Sabine has 3 accounts totaling CHF 240'000. Both plan PK capital withdrawals: Andreas CHF 450'000, Sabine CHF 320'000.

The key factors: 5-account strategy for both partners, one year of retirement offset, and no double withdrawals in one year. That's the combination of savings-phase structure and withdrawal-phase choreography.

Special cases: Divorce, death, self-employment

Divorce

In a divorce, 3a assets accumulated during the marriage are typically split in half — analogous to the pension fund. Prerequisite: no other arrangement in the marriage contract (e.g. separate property).

The calculation runs from the marriage date to the date of divorce initiation. 3a assets accumulated before the marriage remain the respective partner's. The split occurs via account transfer, not capital withdrawal — no tax event.

Death of a spouse

The surviving spouse (or registered partner) is the primary beneficiary. The entire 3a balance of the deceased partner automatically goes to the surviving partner — regardless of the will. This withdrawal is a capital payout and is taxed at the progressive rate.

Important tax optimisation: do NOT realise the inherited 3a withdrawal in the same year as your own 3a or PK withdrawals. The combination rule applies here too.

Self-employment of one partner

If one partner is self-employed without a pension fund, they can use the "big 3a deduction": up to 20% of earned income, maximum CHF 36'288 per year (2026). The other partner with a PK stays at the normal maximum of CHF 7'258.

Consequence: asymmetric savings strategy. The self-employed partner builds much larger assets via 3a — at annual maximum contributions of CHF 36'288 over 35 years, that's CHF 1.3M end balance (4% return) versus CHF 540k for the salaried partner. At withdrawal, the self-employed partner must stagger their withdrawals more finely — ideally 8-10 separate accounts.

Typical couples' mistakes

1. Only one partner contributes to 3a. Forfeits CHF 60'000+ in tax savings over 30 years.
2. Both withdraw everything in the retirement year. Worst-case combination rule. Quickly CHF 30'000-50'000 too much tax.
3. Synchronous 3a withdrawal without a plan. Even with staggering: if both partners withdraw in the same years, amounts are combined again. Alternating years are mandatory.
4. Self-employed partner only contributes CHF 7'258. Those without a PK leave CHF 29'000 of deduction potential unused.
5. Forgotten spouse consent on withdrawal. Every capital withdrawal requires the notarised signature of the spouse — without it, no withdrawal.
6. Divorce agreement without a 3a clause. Those who regulate nothing get the standard 50/50 split. For very asymmetric accounts, an individual clause is worthwhile.
7. Withdrawing inherited 3a balance uncoordinated. Upon death of a partner: don't realise in the same year as your own withdrawals.
8. PK buy-in too late. Anyone making PK buy-ins in the last 3 years cannot withdraw as capital — observe lock-up period.
