Capital gains tax in Switzerland

Switzerland holds an unusual position among developed economies: private capital gains on movable assets are entirely exempt from income tax at federal and cantonal level. The exemption is not automatic for active traders, and separate rules apply to real estate and business assets.

Does Switzerland tax capital gains on shares and funds?

Article 16, paragraph 3 of the Federal Act on Direct Federal Tax (Bundesgesetz uber die direkte Bundessteuer, DBG) provides that gains from selling movable private assets are exempt from federal income tax. Article 7, paragraph 4(b) of the Tax Harmonisation Act (Steuerharmonisierungsgesetz, StHG) extends the same principle to cantonal and communal income tax in all 26 cantons. A private investor resident anywhere in Switzerland -- Zurich, Geneva, or Appenzell -- pays zero income tax on a realised gain from shares, bonds, exchange-traded funds, or crypto held as Privatvermogen (private wealth). This is confirmed by PwC World Tax Summaries for Switzerland and is consistent across the ESTV's published individual-taxpayer guidance. The policy rationale lies in the annual cantonal wealth tax (Vermogenssteuer): private wealth appreciation is already reached each 31 December through wealth tax at rates typically between 0.1% and 0.88% of net assets, so individual realisation events are not taxed as income.

When are gains reclassified as taxable professional-dealer income?

The Article 16(3) DBG exemption applies only to investors acting as genuine private asset managers. If the ESTV determines that an individual is a professional securities dealer (gewerbsmassiger Wertschriftenhandler), all capital gains become taxable as self-employment income under Article 18(2) DBG. Consequences are significant: federal income tax at rates up to 11.5%, cantonal and communal income tax (combined effective rates typically 22% to 45% depending on canton), and AHV/IV/EO social-security contributions of approximately 10% on net self-employment income. On the upside, losses become deductible against other income and carry forward for seven years.

ESTV Kreisschreiben Nr. 36, issued 27 July 2012 and unrevised, sets five safe-harbour criteria. Meeting all five creates a strong presumption of private-investor status; breaching any one triggers scrutiny. The criteria are:

1. Holding period. Securities held for an average minimum of six months before sale.
2. Transaction volume. Combined annual buy-and-sell volume below five times the portfolio value at 1 January of the tax year.
3. Gains-to-income ratio. Net realised capital gains below 50% of total net income for the year.
4. No net leverage. Lombard-loan interest costs do not exceed the dividend and interest income earned on the financed securities.
5. Derivatives limited to hedging. Speculative options or warrant writing is absent; any derivative use is purely for hedging existing holdings.

Criteria 1 to 3 carry primary weight; 4 and 5 serve as supplementary evidence. The Swiss Federal Supreme Court has confirmed in rulings including 2C_868/2008 and 2C_802/2012 that each criterion carries independent weight. A more recent ruling, BGer 9C_666/2024 (February 2025), clarified that an economic connection between share transactions and an employment relationship can reclassify gains as earned income under Article 17(1) DBG even without triggering KS 36 -- specifically where a prearranged employer buyback scheme produced gains that were in substance disguised remuneration.

How does the cantonal real-estate gains tax work?

Switzerland draws a firm legal line between movable assets (shares, crypto) and immovable assets. Gains from selling Swiss real property are not sheltered by Article 16(3) DBG. Instead, each canton levies a separate real-estate gains tax (Grundstuckgewinnsteuer, or impot sur les gains immobiliers in French cantons) under Article 12 of the StHG. There is no federal real-estate gains tax.

The defining feature of the Grundstuckgewinnsteuer is a degressive rate structure: the longer the property is held, the lower the effective tax rate on the gain. Conversely, short-term resales attract surcharges. In Zurich, for example, a resale within one year attracts a 50% surcharge on the base rate; holding beyond five years earns a 5% reduction, growing to 50% after 20 or more years. Geneva applies rates starting near 50% for very short holdings and reaching 0% for ownership of 25 years or more. Rates across the 26 cantons range from under 10% to over 60% on short-term flips. The taxable gain equals the sale price minus the acquisition cost plus documented capital-enhancing renovation expenses (Wertvermehrende Aufwendungen); routine maintenance costs that merely preserve value are not deductible from the gain.

A tax deferral (Aufschub) is available under Article 12(3)(e) StHG if the entire sale proceeds are reinvested within the cantonal timeframe -- typically two years in Zurich, up to three years in some other cantons -- in a replacement primary residence in Switzerland. The deferral rolls the gain forward to the future disposal; it does not cancel the tax. Additional deferral grounds under Article 12(3) StHG include transfers on inheritance, in anticipation of inheritance, and on division of an estate. Most double-taxation treaties assign exclusive taxing rights on Swiss real property to Switzerland regardless of the seller's residency.

How does the same framework apply to crypto?

The ESTV applies the identical private-investor or professional-dealer framework to crypto-assets as to equities. A private holder of Bitcoin or Ether who buys, holds, and sells without leverage, without systematic short-term speculation, and with gains representing a modest share of total income will generally qualify for the Article 16(3) DBG exemption. ESTV has published crypto-specific guidance confirming that Kreisschreiben Nr. 36 criteria apply to crypto trading activity.

Several crypto-specific income streams are taxable as ordinary asset income (Vermogensertrag) regardless of private-investor status: mining income valued at the CHF market price on the date of receipt, staking rewards, DeFi lending proceeds, airdrops, and hard-fork tokens. All crypto holdings are subject to annual cantonal wealth tax; Swiss residents declare balances at 31 December using ESTV-published official valuations (the annual Kursliste) or, for unlisted tokens, prices from recognised exchanges. From 1 January 2027, Swiss law requires crypto-asset service providers to report user transaction and account data under the OECD Crypto-Asset Reporting Framework (CARF); automatic international exchange is expected from around 2028.

What about business assets and self-employed sellers?

Business assets (Geschaftsvermogen) -- property, machinery, shares, and other assets used in a commercial enterprise or held by a self-employed individual as part of their business -- are always outside the Article 16(3) DBG private-asset exemption. Gains on business assets are ordinary business income taxable under Article 18(1) DBG at full income-tax rates plus AHV/IV/EO contributions. The critical distinction between private and business assets depends on the function and economic purpose of the asset, not solely its legal ownership form. Several Federal Supreme Court rulings confirm that years of active involvement in developing or restructuring an investment -- even alongside full-time employment -- can reclassify an asset into the business sphere (BGer 9C_403/2023, June 2024).
