Switzerland Capital Gains Tax Guide 2026

Private Capital Gains — Tax-Free

• General rule: Capital gains realised by private individuals on the sale of movable property (bewegliches Vermögen) — shares, bonds, mutual funds, ETFs, cryptocurrencies, forex, precious metals, and other securities — are tax-free at both federal and cantonal levels. This is a fundamental principle of Swiss tax law and has no equivalent in most other developed countries.
• No holding period requirement: Unlike the US (short-term vs long-term) or many EU countries, Switzerland imposes no minimum holding period for private capital gains to be tax-free. You can buy and sell the same stock within the same day, realise a profit, and pay no capital gains tax. Day trading by private individuals is generally tax-free as long as the activity does not qualify as a professional securities dealing business.
• Capital losses: Since capital gains are tax-free, capital losses on movable property are not deductible for private individuals. There is no capital loss offset against ordinary income or against capital gains (since gains are not taxable in the first place). The loss is simply irrelevant for tax purposes — though it may reduce wealth tax if the asset is still held at year-end.
• Exception — real estate: The tax-free treatment does not apply to real estate capital gains (Grundstückgewinnsteuer), which are taxed at the cantonal level. See the section on real estate gains and our Property Tax Guide → for details.

Professional Securities Dealer Status (Gewerbsmässiger Wertschriftenhändler)

• What it is: If the tax authority determines that you are a professional securities dealer (gewerbsmässiger Wertschriftenhändler), all your capital gains on securities trading are reclassified as taxable business income and are subject to ordinary income tax (federal and cantonal). This applies to both gains and losses (losses become deductible).
• 5-year / 5x turnover test: The widely used guideline is that an individual may be classified as a professional dealer if they hold securities for an average of less than 5 years and the total trading volume over the last 5 years exceeds 5 times the portfolio value. The exact test is not codified in law — it is a "rule of thumb" developed by tax practice. Other factors include: use of derivatives, short selling, margin trading, and the time spent on trading activities.
• Subjective criteria: The tax authority also considers subjective factors: whether the trading activity is systematic (screening, frequent transactions, short holding periods), whether the trader uses substantial leverage (margin), whether the trader has a professional background in finance, and whether the trading generates a significant portion of the taxpayer's income. There is no bright-line rule — the assessment is made on a case-by-case basis.
• Consequences: If classified as a professional dealer, you must: (a) report all gains as taxable income; (b) deduct all losses against gains (and against other income in certain circumstances); (c) pay income tax at ordinary progressive rates (up to 40%+ in high-tax cantons); (d) pay AHV/IV/EO/ALV contributions on the trading income (self-employed person contributions). The professional dealer classification applies from the moment the activity reaches the threshold — there is no grace period.
• How to avoid: To minimise the risk of professional dealer classification: hold securities for longer than 5 years on average; maintain a moderate trading volume relative to portfolio size; avoid excessive leverage and short selling; and avoid claiming a deduction for office space or trading tools. If in doubt, seek a tax ruling (Steuervorbescheid) from the cantonal tax authority — a ruling confirms that your activity does not qualify as professional dealing. Rulings are binding on the tax authority and provide certainty.

Real Estate Capital Gains (Grundstückgewinnsteuer)

• Scope: Real estate capital gains are always taxable regardless of whether the seller is a private individual or a professional dealer. The tax is levied at the cantonal level on the profit realised upon the sale of real estate. The gain is calculated as: sale proceeds minus acquisition cost, minus cost of improvements, plus depreciation previously claimed (if applicable).
• Holding period discount: The tax rate is progressive with the holding period — the shorter you hold, the higher the rate. The rate typically declines from 30–50% for a 1-year holding period to 0–10% for a 25+ year holding period, depending on the canton. This incentivises long-term ownership. Each canton has its own rate table — for example, in Zurich: 0–2 years ~35%, 5 years ~25%, 10 years ~15%, 20 years ~8%, 30 years ~3%.
• Reinvestment relief (Ersatzbeschaffung): If the sale proceeds are reinvested in a replacement principal residence (or in some cantons, replacement investment property) within the period from 1 year before to 2 years after the sale, the tax can be deferred. The deferred gain is effectively rolled into the new property's cost basis. This relief is available once per taxpayer per 5 years (some cantons have no frequency limit).
• Exemptions: Owner-occupiers who sell after age 60, or due to disability, nursing home admission, or death, may be fully or partially exempt from property gains tax. The exact exemption varies by canton — some exempt the entire gain, others apply a reduced rate. Gifts and inheritances are not subject to property gains tax (the gain carries over to the recipient's acquisition cost).

Partial Taxation — Capital Gains for Professionals

• Trading activity: If you are classified as a professional securities dealer (see above), your securities gains are fully taxable as business income. There is no partial taxation — the full gain is added to your ordinary income and taxed at progressive rates (up to 40%+ depending on canton). Losses are deductible against gains and can offset other income (subject to restrictions).
• Self-employed business income: Gains from trading as a self-employed business are also subject to AHV/IV/EO contributions. The AHV contribution rate for self-employed persons is approximately 8.1–10.0% (depending on income level), in addition to income tax. This makes the effective tax rate on trading income significantly higher for professionals than for private individuals.
• Loss carryforward: Professional securities dealers can carry forward trading losses for 7 years (subject to certain restrictions). The loss can offset future trading gains. However, the loss offset is limited to 70% of the gain in a given year in some cantons (following general business loss limitation rules).

Cryptocurrency — Tax-Free for Private Individuals

• Tax-free gains: For private individuals, capital gains on cryptocurrency (Bitcoin, Ethereum, altcoins, DeFi tokens, NFTs) are tax-free under the same principles as securities. You can buy and sell crypto without triggering any capital gains tax. There is no minimum holding period for crypto tax-free treatment.
• Professional dealer risk: However, individuals with very high crypto trading volume may be classified as professional securities dealers (gewerbsmässiger Wertschriftenhändler), which would subject their crypto gains to income tax. The same 5-year / 5x turnover rule of thumb applies. Crypto day traders with high frequency and volume are at particular risk of professional classification.
• Staking and lending income: Income from crypto staking, lending (DeFi), and airdrops is taxable as investment income (not capital gains). The income is the fair market value of the crypto at the time of receipt. For airdrops, the value at receipt is taxable if the airdrop is considered a one-time gift or windfall — the exact treatment depends on the nature of the airdrop (retroactive vs promotional). Mining income is taxable as self-employed or occasional income.
• Reporting: While crypto gains are tax-free for private individuals, the crypto assets themselves are subject to wealth tax. You must declare your crypto holdings (quantity and value in CHF) on your annual tax return. The valuation is the market value as at 31 December. Failure to declare crypto assets can result in penalties for tax evasion. Swiss tax authorities are increasingly receiving crypto account data through automatic exchange of information (AEOI) agreements and targeted requests to exchanges.

Non-Residents — Swiss Real Estate Gains Only

• Limited Swiss tax exposure: Non-residents are subject to Swiss capital gains tax only on Swiss real estate (Grundstückgewinnsteuer). Gains on movable property (shares, bonds, crypto) held by non-residents are not taxable in Switzerland, even if the securities are issued by Swiss companies.
• Withholding on sale: Upon the sale of Swiss real estate by a non-resident, the cantonal tax authority will generally withhold 20% of the gain (or 5% of the sale price) as a deposit against the final property gains tax assessment. The non-resident must file a property gains tax return (Grundstückgewinnsteuererklärung) within 30 days of the sale to obtain the final assessment. The deposit is refunded once the tax is settled.
• Tax treaty protection: Most Swiss double tax treaties provide that capital gains on movable property are taxable only in the country of residence of the seller. Gains on real estate are taxable in the country where the property is located (situs principle). For a non-resident selling Swiss real estate, the gain is taxable in Switzerland; the residence country may provide a credit for the Swiss tax paid under the relevant treaty.

FAQs

Are capital gains on shares really tax-free in Switzerland?

Yes, for private individuals. Capital gains on shares, bonds, mutual funds, ETFs, cryptocurrencies, and other movable property are tax-free at both federal and cantonal levels. There is no minimum holding period. This is a key advantage of the Swiss tax system for investors. However, dividends and interest are fully taxable as investment income. And if you qualify as a professional securities dealer, your gains become taxable as business income.

When is a private investor considered a professional securities dealer?

The tax authority looks at objective and subjective factors. The most commonly cited rule of thumb is the 5-year / 5x turnover test: if you hold securities for an average of less than 5 years AND your trading volume over the last 5 years exceeds 5 times your portfolio value, you may be classified as a professional dealer. Other factors: use of derivatives, short selling, margin trading, time spent, financial background. The classification is made on a case-by-case basis — a tax ruling can provide certainty.

Are losses on share trading deductible?

No, for private individuals. Since capital gains are tax-free, capital losses on movable property are not deductible. The loss is simply disregarded for tax purposes. However, if you are classified as a professional securities dealer, losses become deductible against gains (and can offset other income subject to restrictions). Losses on real estate sales are not relevant — property gains tax is only applied on gains, and losses are not refundable or deductible.

Is cryptocurrency taxed differently from shares?

For capital gains purposes, no — crypto gains are tax-free for private individuals just like shares. The same professional dealer rules apply. However, crypto staking, lending (DeFi), and airdrop income may be treated as taxable income (investment income or occasional earnings) and must be declared. Mining income is generally taxable as self-employed or occasional income. Crypto holdings are subject to wealth tax and must be declared at their year-end market value.

How is the Grundstückgewinnsteuer calculated if I sell my house after 20 years?

The tax is calculated on the gain (sale price minus acquisition cost minus improvements). The rate depends on the holding period. After 20 years in Zurich, the effective rate is approximately 5–12% of the gain (depending on the gain amount). After 30 years, the rate drops to 0–5%. Each canton publishes its own rate table (Richtlinien). If you are 60+ or moving to a nursing home, the tax may be entirely exempt in your canton.
