Switzerland — Tax: Capital Gains
For private individuals domiciled in Switzerland, capital gains on liquid assets such as securities held as private assets are generally not taxed; income such as interest and dividends is taxed instead. The boundary is trading activity: once trading goes beyond simple management of private assets, the gains count as income from self-employment, and business angels may be treated as professional investors who lose the exemption. Gains on real estate are taxed separately at cantonal level and on assets held in a business as ordinary income; the rules for those are not covered in these official pages, so ask the cantonal tax office.
Why this matters
The private capital gains exemption on securities is a major reason Switzerland is attractive to investors and retirees living off portfolio income — but the 'professional trader' reclassification risk and the separate, often-overlooked real estate gains tax both catch newcomers by surprise.
Key facts
- Private individuals generally pay no tax on capital gains from liquid assets such as securities held as private assets.
- Interest and dividends are taxed as income.
- Trading that goes beyond simple management of private assets counts as income from self-employment; business angels may be treated as professional investors.
- Real estate gains and business-asset gains follow other rules; ask the cantonal tax office.
Steps
- Confirm private-investor status — Review the Federal Tax Administration's five safe-harbour criteria (holding period, trading volume vs. wealth, use of leverage, etc.) to confirm gains will be treated as tax-free.
- Track real estate holding period — For property, holding period directly reduces the cantonal capital gains tax rate on eventual sale.
- Declare exempt gains for wealth tax purposes — Even tax-free gains still increase reportable net wealth for the annual wealth tax return.
Common mistakes
- Trading so frequently that the tax authority treats the gains as self-employment income.
