Capital Gains Tax in Switzerland: Private Gains, Business Gains, and the Exceptions

For private individuals, Switzerland generally does not tax capital gains on movable assets. A profit from selling listed shares, fund units, bonds or cryptocurrency held in a personal portfolio is, as a rule, free of income tax. The rule is written into federal law at article 16 paragraph 3 of the Federal Direct Tax Act (DBG art. 16 para. 3) and mirrored in every cantonal code through the tax-harmonisation law (StHG art. 7 para. 4 lit. b). It is one of the country's most cited attractions for investors and relocating families.

The exemption is not unconditional. It covers private wealth held as a passive investment. It does not extend to real estate, which is caught by a separate cantonal property-gains tax, to anyone the authorities classify as a professional securities dealer, or to gains realised inside a company, where a profit is ordinary taxable income. This guide sets out exactly where the line falls: asset by asset, for residents and non-residents, for individuals and companies, and it separates capital gains from the two taxes most often confused with it, wealth tax and the 35% withholding tax.

No, Switzerland levies no general capital gains tax on private movable assets. A private investor who sells listed shares, fund units, bonds or privately held cryptocurrency at a profit owes no income tax on that gain, under DBG art. 16 para. 3. The relief is automatic: there is no annual exemption to track and no minimum holding period to earn it.

Two exceptions sit on top of that headline. First, real estate is always taxed, through a dedicated cantonal property-gains tax. Second, if you trade as a profession, the authorities can reclassify your gains as taxable self-employment income. A third boundary applies to companies, whose gains are ordinary taxable profit. Everything else in this guide is detail on those three lines.

Because the exemption is conditional rather than absolute, "tax-free" is true only for a private investor holding movable wealth who is not a real-estate seller, not a professional dealer, and not transacting through a company. A page that states those conditions plainly is more reliable than one that asserts a flat "no capital gains tax".

If the Federal Tax Administration reclassifies you as a professional or commercial securities dealer (gewerbsmässiger Wertschriftenhändler), your gains stop being tax-free. They are recharacterised as self-employment income, taxed at your ordinary rate, and become subject to AHV/AVS contributions. The framework comes from federal court practice and the FTA's Circular No. 36 (KS 36, dated 27 July 2012), which sets out a safe harbour.

Under that safe harbour, an individual is treated as a private investor when all five of the following hold:

• Securities have been held for an average of at least six months.
• Annual transaction volume is no more than five times the portfolio value at the start of the tax period.
• Realised capital gains make up less than half of net income, so gains are not needed to cover living costs.
• Positions are not debt-financed beyond a limited margin.
• Derivatives are used only to hedge the taxpayer's own holdings, not to speculate.

This is a safe harbour, not a hard rule: meeting every condition gives strong comfort that gains stay exempt, while missing one does not automatically make you a dealer, it returns the question to a full weighing of indicators. If you are reclassified, the gains are taxed as ordinary self-employment income plus AHV/AVS, which can be materially higher than zero. To stay inside the harbour, the practical recipe is to buy and hold, avoid leverage and limit speculative derivatives. Where the position is genuinely borderline, an advance tax ruling confirms the treatment before you trade at scale.

Privately held cryptocurrency is treated as movable private wealth, so a gain on selling Bitcoin, Ether or similar payment tokens from a personal holding is, as a rule, tax-free under the same article 16 paragraph 3 principle that covers shares. The same five-criterion safe harbour applies: high-frequency or leveraged crypto trading can tip you into professional-dealer status, at which point the gains become taxable.

Two things are taxed even when the disposal gain is not. First, the tokens themselves are subject to the annual wealth tax, valued at the FTA's year-end rates, not on disposal. Second, rewards from staking, mining, lending and airdrops are income, taxed at fair market value when received, rather than exempt capital gains. To avoid accidentally becoming a professional crypto trader, the same discipline applies as for securities: hold rather than churn, avoid leverage, and keep derivatives to genuine hedging.

The cantonal valuation rates, wallet reporting and the income-versus-gain split are set out in our dedicated Swiss crypto tax guide. Founders running token operations as a business, rather than holding privately, should look at the crypto company route, where the analysis is corporate rather than personal.

The treatment for non-residents tracks the asset, not the residence. A non-resident's gain on Swiss securities held as private wealth is exempt, exactly as it is for a resident, unless the activity amounts to professional trading. Switzerland does not reach across the border to tax a foreign investor's portfolio gains.

Swiss real-estate gains are different. They are taxed by the canton where the property sits, under limited tax liability (beschränkte Steuerpflicht) based on economic affiliation. A non-resident selling Swiss property owes the cantonal property-gains tax regardless of where they live, and some cantons require a security deposit or withholding at the point of sale to secure the tax.

A note for US citizens: the Swiss exemption does not remove your US tax exposure. Under the saving clause in the Switzerland-US tax treaty, the United States continues to tax its citizens on worldwide gains, so a US person can be tax-free in Switzerland yet still owe US capital gains tax. This is a cross-border situation that warrants specialist advice rather than a general rule.

Two doctrines turn what looks like a tax-free private share sale into taxable income, and both catch owner-managers selling a closely held company. They exist precisely to stop the capital gains exemption being used to extract company reserves tax-free.

Indirect partial liquidation (indirekte Teilliquidation) applies when you sell shares from private wealth to a buyer who then funds the purchase price out of the company's distributable, non-operating reserves. What you booked as a tax-free gain is recharacterised, in part, as a taxable dividend in your hands. Transposition applies when you sell your own private shareholding to a company you also control, above nominal value, converting taxable substance into a gain that would otherwise escape tax.

Because both rules hinge on transaction structure rather than intent, you cannot rely on the headline exemption when selling a company stake. The safe course before any sale of a closely held company is to map the buyer's financing and the reserve position, and where the amounts are material, to secure an advance tax ruling. These are areas where a specialist should confirm the precise statutory references for your facts.

For most private investors the conclusion is the headline one: the gain is tax-free. The value in the detail is catching the minority of cases where it is not, and the cleanest way to remove doubt is an advance ruling. A Swiss tax ruling (Steuervorbescheid) is a written confirmation from the cantonal authority of how a specific transaction will be taxed, binding so long as you carry it out as described. It is the right tool for a company-stake sale exposed to the anti-abuse rules, a borderline professional-trader profile, or a non-resident property disposal.

The cantonal dimension cuts across everything above. Corporate effective rates, wealth-tax bands and property-gains schedules all differ by canton, which is why low-tax cantons such as Zug, at roughly 11.85% effective corporate tax, feature so heavily in structuring decisions. If your situation runs beyond the simple private-investor case, the practical next step is to talk to a specialist who can confirm the treatment and, where it helps, arrange a ruling before you transact.
