Is the SICAV a tax-free investment reserved for large fortunes?

The acronym SICAV appears in most bank and insurance offers. It suggests a sophisticated, tax-protected product reserved for large fortunes. Searches for "comunus sicav", "popso" and "comunus" point to funds linked to a regional Ticino bank, which many savers perceive as an all-in-one solution. Three confusions compound this: Luxembourg or Swiss SICAV, contractual investment fund, pension investment.

This article puts five common claims to the test of Swiss law in force in 2026. Each receives a verdict, a figure-based proof and a practical consequence for the investor in French-speaking Switzerland.

False. A 35% withholding tax is deducted at source on dividends and interest from Swiss sources, including when they pass through a collective investment scheme. The vehicle and the holder are not subject to the same regime.

The SICAV is an investment company with variable capital governed by the Federal Act on Collective Investment Schemes (CISA, known in French as LPCC). At the level of the vehicle, taxation is relieved: a fund does not in principle bear profit tax in the way a commercial company does, subject to its direct real estate income. This regime is not passed on to the investor.

For an individual resident in Geneva, three taxes remain:

• Distributed income is taxed as income from movable assets, at the marginal rate, in the tax return (LIFD, art. 20).

• The value of the units at 31 December is taxed as wealth, according to the cantonal scale.

• The 35% withholding tax deducted on income from Swiss sources is merely an advance payment: it is recoverable via the tax return, provided that the securities and yields appear in it.

Under the Federal Act on Withholding Tax, the 35% deduction on Swiss capital income is refunded only to the taxpayer who regularly declares securities and yields; an omission entails the loss of the refund and a back-tax procedure.

Consequence: a fund that distributes CHF 3'000 of Swiss income suffers a deduction of CHF 1'050. This amount is returned only if the tax return is complete. This article does not concern tax evasion: it concerns accuracy in declarations.

Partly. The difference is legal, not fiscal. For a private individual in Switzerland, the legal wrapper does not alter the calculation of income tax or wealth tax.

The CISA distinguishes several forms. The SICAV is a company with legal personality, whose capital varies with subscriptions and redemptions. The contractual investment fund is a contractual relationship between the fund management company, the custodian bank and the investors, without legal personality. Both are subject to authorisation and supervision by FINMA.

What really changes:

• Governance: board of directors and shareholders' meeting for the SICAV, fund management company and custodian bank for the contractual fund.

• The cost structure and the prospectus, to be compared product by product.

• The investor's position: shareholder of a company on the one hand, unit holder on the other.

Beware of SICAVs governed by Luxembourg or Irish law offered in Switzerland. Their domicile influences the treatment of withholding tax: a deduction may be made abroad, not recoverable in the same way. The key information document (KID, known in French as FIB) states the domicile.

Consequence: do not choose on the basis of the acronym. Compare the domicile, the regime stated in the prospectus and the ongoing charges.

To be verified product by product. The funds associated with the names Comunus and Popso are marketed by Banca Popolare di Sondrio (Suisse). This says nothing about their actual accessibility to a given investor.

Eligibility depends on each collective investment scheme: type of investor authorised (public or qualified), distribution channels, minimum subscription, fund domicile, unit classes available. None of this information can be deduced from a trade name.

Checks to carry out before any step:

• The fund's prospectus and KID, which specify the target investors, the domicile and the reference currency.

• The ongoing charges (TER), entry and exit fees: to be verified in the prospectus; no figure should be adopted without a source.

• Currency risk if the fund's currency differs from the Swiss franc.

• The authorisation of the collective investment scheme on FINMA's list of authorised collective investment schemes.

FINMA maintains a public list of collective investment schemes authorised in Switzerland, available at finma.ch; a fund absent from this list cannot be offered to the public without authorisation.

Consequence: a product linked to a regional bank is neither prohibited nor mandatory for its clients. Only the fund's official documents settle the matter. No past performance constitutes a promise.

False as it stands. A global equity fund can lose 20 to 30% in a bearish year; a single-country or thematic fund, more. Diversification stems from the composition of the portfolio, never from the legal wrapper.

A SICAV concentrated on a single sector, region or asset class exposes the investor to concentrated risk, even if it holds several dozen positions. Conversely, a broadly diversified contractual fund offers genuine dispersion. The acronym guarantees nothing.

Two indicators should be read before any purchase:

• The synthetic risk indicator (SRRI or SRI) from 1 to 7, presented in the KID: a level of 6 or 7 signals high volatility.

• The ongoing charges ratio (TER), expressed as an annual percentage: a TER of 1.5% on CHF 100'000 represents CHF 1'500 per year, deducted regardless of performance.

The KID, a standardised two-page document, presents the risk indicator from 1 to 7 and the ongoing charges; consulting it legally precedes the subscription of a collective investment scheme offered to the public.

Consequence: compare the composition (number of positions, weighting by country and by sector, currency), the risk level and the costs. This reading takes twenty minutes and avoids paying fees for illusory diversification.

Nuanced. For a private individual, capital gains on private wealth are in principle exempt (LIFD, art. 16, para. 3), unless the tax authority classifies the activity as professional securities trading. By contrast, distributions are taxed.

Accumulation funds reinvest income. Their taxation does not disappear for all that: depending on the type of fund and the declaration to the tax authorities, accumulated income may be taxable in the hands of the holder. The regime should be verified in the prospectus and with the cantonal tax administration.

Comparison with pension tools:

• An LPP buy-in of CHF 50'000 saves approximately CHF 17'000 in tax in Geneva for an income of CHF 150'000: no SICAV offers this deduction.

• Pillar 3a allows a deduction of up to CHF 7'258 (employee affiliated to a pension fund, 2026 scale) from taxable income.

• For a homeowner, the calculation of the rental value and the deduction of mortgage interest also enter into the trade-off between repaying the home and free investment.

For a self-employed person or an SME, the company's holding of fund units changes the reasoning: the income increases the result taxable to profit tax, while any provision or write-down follows precise accounting and tax rules.

Consequence: a SICAV is not a tax optimisation instrument. It is an investment tool, to be considered after using the available pension deductions. A fiduciary calculates the trade-off on your actual situation.

Five checks precede any investment in a SICAV or fund:

• Read the KID and the prospectus: domicile, type of investor, risk indicator from 1 to 7, currency.

• Calculate the total cost in CHF: TER, entry and exit fees, transaction costs.

• Verify the treatment of withholding tax and the fund's domicile, which condition the refund of the 35%.

• Declare all securities and yields, including accumulations, to preserve the right to a refund.

• Compare with an LPP buy-in and a pillar 3a before any free investment: the tax deduction there is immediate and quantifiable.
