When Pillar 3a Is NOT Worth It: 8 Situations to Reconsider

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

We at arvy offer Pillar 3a solutions. Yet we're writing this article — because 3a isn't right for everyone in every life situation. Many Swiss finance blogs preach blanket "always max out 3a". That's true for the majority. But there are clear situations where you're better off skipping the 3a — or at least putting it on the back burner. This honest stocktaking shows you 8 concrete cases when you should skip the contribution, what's the better alternative, and where the edge cases lie.

8 cases
Where 3a contributions are not (or less) worthwhile
CHF 30'000
Taxable income below which 3a becomes questionable
35 years
Maximum capital lock-up — the big trade-off

Why we're writing this article

Pillar 3a is a politically created instrument — it has clear advantages, but also clear limits. The main advantages are undisputed: tax deduction on contribution, tax-free growth, separate taxation on withdrawal. In total, an average Swiss employee saves around CHF 60'000-100'000 in tax over 30 years through consistent 3a contributions.

But 3a also has costs:

  • Capital lock-up until earliest 5 years before AHV retirement age (usually age 60)
  • Restricted investment options — no direct investment in individual stocks, no crypto, no alternative investments
  • Withdrawal as capital is taxed (albeit at reduced rate)
  • Early withdrawal options are limited: home ownership, self-employment, emigration, IV — otherwise no
  • 3a balances at death follow a statutory order, not the will

For most Swiss employees, the advantages clearly outweigh. But for a significant minority, the disadvantages prevail. This minority is not addressed by typical "3a optimisation marketing" — and often makes costly mistakes.

Our standard: We earn money when you open a 3a at arvy. Yet it's important to us to give you the honest answer. If 3a doesn't fit your situation, an open recommendation against the 3a contribution is better for our long-term relationship — and for your finances.

The 8 situations where 3a isn't (or less) worthwhile

Case 1

Very low income (taxable under CHF 30'000)

Tax savings through 3a equal your personal marginal tax rate × contribution. At taxable income under CHF 30'000, this marginal tax rate is under 10%. On a maximum 3a contribution of CHF 7'258, you save under CHF 725 in tax. In return, you lock up the capital for 35+ years.

At this trade-off, free investing with liquidity flexibility is often the better choice — especially for young employees at career start or people in part-time employment with other income sources.

Instead: Build an emergency fund (3-6 months of salary), pay down debts (if any), then build a free securities portfolio with ETFs — flexible, available anytime. As income rises, you can switch to 3a contributions.
Case 2

Likely emigration in the next 5 years

Those moving abroad in the foreseeable future only partially benefit from 3a. When moving within EU/EFTA with employment, you may only withdraw the over-mandatory portion — the mandatory portion remains on a vested benefits account in Switzerland (for decades).

When moving outside EU/EFTA, you can withdraw everything — taxed with withholding tax in the departure canton (typically 4-12%). This is cheap, but the tax savings on contribution were only partially realised (short contribution period = less compound effect).

Instead: If emigration is planned in 1-3 years, stop making new 3a contributions. Instead build flexible assets (securities, check retirement account in target country). Withdraw existing 3a accounts only at actual emigration — moving to a tax-favourable departure canton beforehand can reduce withholding tax.
Case 3

High short-term liquidity need (2-5 years)

Those who need larger cash flows in the next 2-5 years — home purchase, business founding, sabbatical, family planning with income reduction — should put 3a on the back burner. The money in 3a is locked up. Yes, there are early withdrawal options for home ownership and self-employment, but:

  • Early withdrawal for home ownership: immediately taxed (at withdrawal tax)
  • Early withdrawal for self-employment: only once in the first 12 months of self-employment
  • You lose future tax deferral effects
Instead: Liquid savings (call money, short bonds) for short-term goals. Only after the liquidity event start 3a. Those buying a home in 5 years should not park equity in 3a — early withdrawal costs the tax effect.
Case 4

Open favourable PK buy-in opportunities

At high income (typically CHF 200'000+) and free PK buy-in capacity, the PK buy-in can be superior to 3a. Three reasons:

  • Higher tax savings: at steeper progression stages, you save more per franc contributed
  • Higher contributions possible: PK buy-in gaps are often CHF 100'000+, instead of CHF 7'258 annually
  • Identical withdrawal optimisation: PK capital withdrawal follows the same staggering logic as 3a

Those who can do both in parallel (high cash flow) do both. Those who must prioritise cash flow should tackle the PK buy-in first depending on the constellation.

Instead: Ask your pension fund about your buy-in gap. If the gap is > CHF 50'000 and you're a high earner: fill up PK first, then 3a. Observe lock-up: no capital withdrawal for 3 years after PK buy-in.
Case 5

Imminent separation or divorce

On divorce, 3a assets accumulated during marriage are split in half — analogous to the pension fund. Those facing imminent separation effectively contribute to the soon-to-be-ex-partner's assets with every 3a contribution.

Even during the separation phase (between separation and divorce), caution is warranted: contributions made after separation can be treated differently in the split — cantonal case law varies.

Instead: If separation looms, pause 3a contributions and build free assets instead — these fall under matrimonial property law splitting, but treatment is often clearer and more predictable. Consult a lawyer before contributing large amounts to 3a.
Case 6

Serious illness or shortened life expectancy

Pillar 3a is designed for long-term tax deferral — the effect plays out over 20-40 years. With serious illness or shortened life expectancy, this effect isn't fully realised. Also:

  • At death, the 3a goes to a statutory beneficiary order, not testamentary heirs
  • Withdrawal options at full disability are possible, but bureaucratic
  • Tax on a late withdrawal is no cheaper than a free withdrawal from assets today
Instead: On serious diagnosis with shortened life expectancy: no new 3a contributions. Realise existing amounts via early withdrawal on IV pension if applicable. Discuss liquidity planning with tax advisor and notary.
Case 7

Young startup founder with cash flow need

In the early startup phase, cash flow is the most important asset. CHF 7'258 annually locked in 3a can decide between survival and business closure when business is tight. Even if tax savings are 25-30%: 100% of cash flow is usually better allocated in the growing business.

Rule of thumb: 3a contributions make sense in a startup when you:

  • Have 6-12 months of personal living expense reserves
  • The business is operationally profitable (or has > 18 months runway)
  • The contribution doesn't constrain your business decisions
Instead: Keep cash in the business, build personal reserves. Only start 3a when the business runs stably and you don't need "too much capital" privately. Bonus: introduced in 2025: 3a retroactive contributions up to 10 years back — you can catch up on founding years later.
Case 8

High consumer debt with double-digit interest rates

Those with credit card debt at 10-15% interest or personal loans at 5-12% open should pay these off first — before making 3a contributions. The reason is simple math:

  • Credit card interest: 10-15% p.a. (guaranteed burden)
  • 3a tax savings: 20-30% × contribution (one-off, in the contribution year)
  • 3a return long-term: ~5% p.a. (with fluctuations)

Debt repayment guarantees a "return" equal to the interest. At 12% credit card interest, that's a guaranteed 12% return — beats any 3a strategy.

Exception: Mortgages at 1-3% interest are often cheaper than the long-term 3a return + tax effect. Here 3a alongside the mortgage makes sense.

Instead: First pay off all consumer debt (credit cards, personal loans, leasing over 5% interest). Then build emergency fund. Then start 3a. Mortgage can run in parallel — no rush to pay down at low interest rates.

When 3a almost always pays off

For balance: for the large majority of Swiss employees, 3a is a no-brainer. It practically always pays off in the following constellations:

Yes

Stable employment with medium to high income

Taxable income from CHF 50'000 in Switzerland, longer-term employment or established self-employment, retirement planned in Switzerland. Here 3a typically yields CHF 100'000+ net benefit over the career (tax savings + tax-free growth + reduced withdrawal tax).

Yes

High earners with maxed-out PK

Those without any remaining PK buy-in gap should definitely max out 3a. At a marginal tax rate of 35%+, the effective "instant return" on contributed francs is over 50% — followed by 30+ years of tax-free growth.

Yes

Self-employed without a pension fund

The big 3a deduction up to CHF 36'288 is the most important retirement optimisation for Swiss self-employed without PK — without this option, Swiss old-age provision would be unbalanced for self-employed. More on this: Pillar 3a for Self-Employed.

Yes

Dual-earner couples with family

Per couple up to CHF 14'516 annual contribution × 30-35 years × tax deferral effect × withdrawal optimisation = one of the largest available tax-driven wealth accumulation effects in Switzerland. More on this: Pillar 3a for Married Couples.

The honest comparison: 3a vs. free investing

One of the most important comparison calculations for Pillar 3a isn't "3a vs. savings account" (3a wins clearly), but "3a vs. free securities portfolio". That's the real competition.

AspectPillar 3aFree securities portfolio
Contribution tax-deductibleYes (~25% savings)No
Tax liability on returnsNone during termDividends fully taxable
Capital gainsTaxed on withdrawal (4-12%)Tax-free (private individuals)
Wealth tax on holdingsNoneYes (0.1-0.7% cantonal)
FlexibilityLocked until withdrawalAvailable anytime
Investment universeRestrictedFree
InheritanceStatutory orderWill-based

With long investment duration (30+ years) and stable income, 3a typically beats the free portfolio — mainly because of the upfront tax savings on contributions. With short horizon, fluctuating life situations, or special investment preferences, the free portfolio can be superior.

Pragmatic recommendation: Those who have both fare best. Maximum 3a contributions plus additional free portfolio is the ideal combination for stable employees. Those who must choose: 3a for tax deferral, free portfolio for flexibility.

Decision framework: Three questions before every 3a contribution

Before making your next 3a contribution, honestly answer these three questions:

Question 1: Do I need this money in the next 5 years?
  • Home purchase planned? Family planning? Self-employment? Sabbatical?
  • If Yes to any: prioritise liquidity, put 3a on the back burner
  • If No: check 3a contribution
Question 2: Do I have more expensive debts or unused cheaper retirement levers?
  • Consumer debt with interest over 5%? → Pay off first
  • PK buy-in gap unused? → For high income, PK first
  • Emergency fund under 3 months of salary? → Build reserve first
  • If all clarified: 3a contribution sensible
Question 3: Am I realistically staying in Switzerland?
  • Emigration plans in the next 5 years?
  • International career opportunity likely to be taken?
  • Foreign partner with return wishes?
  • If Yes: 3a contributions restricted or paused
  • If No: full Pillar 3a sensible

The honest conclusion: For the majority of Swiss employees, maximum 3a contribution is the right strategy. But "majority" isn't "everyone". Those in one of the 8 situations described above should question 3a — not abolish it, but tackle it in the right sequence.

Frequently asked questions: When not 3a?

When is Pillar 3a not worth it?
In 8 typical cases: very low income (taxable under CHF 30'000), likely emigration in 5 years, high liquidity need, open PK buy-in opportunities, imminent divorce, serious illness, startup cash-flow need, consumer debt with high interest rates.
From what income does Pillar 3a become worthwhile?
Rule of thumb: from CHF 40'000 taxable income. Below that, the marginal tax rate is so low (under 10%) that tax savings barely justify the capital lock-up.
Should I pay down debt or contribute to 3a?
Pay off consumer debt first (credit cards 10-15%, personal loans 5-12%) — guaranteed "return" exceeds 3a significantly. Mortgage interest (1-3%) is lower than long-term 3a return — here 3a in parallel.
PK buy-in or Pillar 3a — what's better?
At high income (CHF 200'000+) with free PK gap, buy-in is often better: higher tax savings, same withdrawal optimisation. At limited cash flow: first PK, then 3a. Observe 3-year lock-up.
What happens to my 3a when emigrating?
Outside EU/EFTA: everything withdrawable, withholding tax in departure canton. Within EU/EFTA with employment: only over-mandatory portion — mandatory portion stays on vested benefits account.
Should I as a startup founder contribute to 3a?
Usually no in the early phase — cash flow in the business is more important. Rule of thumb: only start 3a after 6-12 months living-expense reserve and stable business.
Is 3a still worth it shortly before retirement?
Yes, practically always up to ~5 years before retirement. Tax savings (20-35%) significantly exceed withdrawal tax (4-12%). Exception: 3-year lock-up after PK buy-in.
How much tax do I actually save with 3a?
Marginal tax rate × contribution. At CHF 60'000 income ZH: ~CHF 1'600. At CHF 100'000: ~CHF 2'000. At CHF 150'000: ~CHF 2'400. Self-employed without PK can contribute up to CHF 36'288 — up to 5× more savings.
