In short: In Switzerland, capital gains on privately held securities are tax-free – at both federal and cantonal level, with no holding-period requirement (Art. 16 para. 3 DBG/LIFD). What is taxed is dividends and interest: they are added to your other income and taxed at the ordinary progressive rate (federal + cantonal + communal). On Swiss-source dividends and interest the federal government levies a 35% Anticipatory (withholding) Tax; as a resident you get it fully credited or refunded if you declare everything correctly. For ETFs only the income component (dividends/interest) matters – accumulating or distributing makes no difference for income tax.
Capital gains and investment taxation in Switzerland (2026)
Switzerland has a feature that surprises many investors: capital gains on private securities are tax-free. In return, dividends and interest are taxed as ordinary income, on a progressive scale that varies a lot by canton. In this lesson we walk calmly through the rules for the 2026 tax year, including ETFs, the withholding tax and Pillar 3a. This is general financial education, not tax advice, and rules can change.
Confirm you invest privately and are not treated as a professional securities dealer – then your price gains are tax-free.
List every security in the securities schedule of your return so you get the 35% withholding tax back.
Look up the taxable income per unit for your ETFs in the ICTax portal (ictax.admin.ch).
Use Pillar 3a to shelter income and wealth, and check Form DA-1 for foreign withholding taxes.
What matters
Three levels of tax, one core principle. Switzerland taxes individuals at the federal (direct federal tax), cantonal and communal level. Rates are progressive and differ markedly by where you live. There is no separate flat tax on investment income: dividends and interest are added to your other income and taxed at your personal marginal rate.
Capital gains: the defining feature. Realized gains on movable private assets – shares, ETFs, bonds, even crypto – are tax-free for private individuals (Art. 16 para. 3 DBG/LIFD), at both federal and cantonal level, with no holding period required. You lose this only if you are reclassified as a professional securities dealer. The Federal Tax Administration assesses this under Circular No. 36. If you meet all five safe-harbour criteria you are definitively a private investor: the (weighted) average holding period of your securities is at least 6 months; total transaction volume no more than 5x your portfolio value at the start of the year; capital gains below 50% of net income; no debt-financed purchases; derivatives used only to hedge.
Dividends and interest. Both are taxable income at ordinary rates. On Swiss sources the federal government levies a 35% Anticipatory Tax at source – but for residents it is not a final tax: it is fully recoverable on correct declaration in the securities schedule. A partial-taxation relief (only 70% taxable at federal level) exists only for qualified participations of 10% or more – practically irrelevant for an ordinary diversified portfolio.
What there isn't. No general allowance for investment income, and no ISA- or PEA-style brokerage wrapper. The main tax-advantaged wrapper is Pillar 3a: contributions are deductible, and income and assets inside it are exempt from income and wealth tax. On top of this, wealth tax applies to securities, funds and crypto at their 31 December market value.
ExampleExample: you hold Swiss shares that pay a CHF 2,000 dividend in 2026. The company withholds 35% Anticipatory Tax – CHF 700 – and pays you CHF 1,300. In your return you declare the full CHF 2,000 in the securities schedule. The CHF 700 is then fully credited against your tax bill or refunded. The dividend itself is taxed at your ordinary progressive rate. If you later sell the same shares for a CHF 10,000 price gain, you owe nothing on it – capital gains on private assets are tax-free.
Plan income and reinvestment over the long run: a compound-interest calculator shows how much more builds up over the years inside a tax-efficient wrapper such as Pillar 3a.
In depth
ETFs and funds: only the income counts
Funds are generally transparent for income: you are taxed on the fund's income component (dividends and interest), regardless of whether it distributes or accumulates. Capital gains realized inside the fund stay tax-free for you – but only if they are shown separately from income (a separate coupon). That is exactly why the ICTax classification matters: if a fund does not cleanly separate capital gain from income, you risk the whole distribution being taxed as income. A special rule applies to Swiss direct-real-estate funds: these are taxed at fund level, and the corresponding income is exempt at the investor level to avoid double taxation.
Foreign withholding tax and Form DA-1
Foreign dividends – inside or outside funds – often carry foreign withholding tax. Switzerland gives relief two ways: reclaiming the recoverable portion from the source country under the treaty, and the lump-sum tax credit for the non-recoverable residual via Form DA-1 filed with your cantonal return. In practice: the non-recoverable foreign tax must total at least CHF 100, the claim is valid for up to three years, and the credit is capped at the Swiss tax attributable to that income. Note that withholding tax suffered inside an accumulating foreign fund generally cannot be recovered by the individual.
Wealth tax and stamp duty
Securities, funds and crypto are part of your taxable net wealth, valued at 31 December market value (per the official price list / ICTax). Wealth tax is cantonal and communal and broadly ranges from 0.1% to 1%, with tax-free allowances commonly around CHF 100,000 per adult (canton-dependent). Trading through a Swiss securities dealer also triggers stamp duty: 0.15% on Swiss securities and 0.30% on foreign ones. This is a transaction tax, not income tax – trading via a foreign broker generally avoids it. Bear in mind these are federal or typical figures; cantonal rates and allowances change yearly, so check your specific canton.
Checklist
Are all securities and income entered in the securities schedule so the 35% comes back?
Do I meet the five safe-harbour criteria of Circular 36 (e.g. 6-month holding period)?
Have I checked the taxable income for my ETFs in ICTax – income shown separately from capital gain?
For foreign withholding taxes of at least CHF 100, is Form DA-1 worth filing?
Common myths
Myth: In Switzerland, gains on shares and ETFs are always completely tax-free.
Reality: For private investors, yes – but if you are classified as a professional securities dealer, gains are taxed as income and social-security (AHV/AVS) contributions apply on top.
Myth: Accumulating ETFs save tax because nothing is paid out.
Reality: No. The accumulated income is taxed each year as if it had been distributed. You find the amount per unit in the ESTV price list via ICTax.
Do I have to pay tax on gains from selling shares or ETFs?
As a private investor, no: realized capital gains on movable private assets are tax-free, with no minimum holding period. The only exception is if the tax authorities classify you as a professional securities dealer – then gains are taxed as income and social-security (AHV/AVS) contributions apply.
How do I get the 35% withholding tax back?
By declaring the securities and their income in the securities schedule of your tax return. The 35% is then credited against your tax bill or refunded. If you fail to declare, the amount is forfeited – that is precisely the purpose of the tax: to enforce honest declaration.
Are accumulating ETFs taxed differently from distributing ones?
Not for income tax. With accumulating funds the reinvested income is still taxed each year as if it had been paid out – a form of deemed or notional taxation. The relevant amount per unit is published yearly by the Federal Tax Administration (ESTV) in the official price list via ICTax.
