Taxes on Shares in Switzerland 2026: What You Pay

Selling shares at a profit in Switzerland costs you zero capital gains tax as a private investor. That's the good news. The less obvious part: you still pay stamp duty on every trade at a Swiss broker, income tax on dividends, the 35% withholding tax (which you get back) and wealth tax. Which of these you pay, and how much paperwork you do, depends a lot on your broker. New to investing? Start with how to buy shares.

Which taxes do you pay on shares in Switzerland?

Here's every tax that touches a Swiss private investor's share portfolio, and whether your broker choice changes it.

The short version: taxes on shares in Switzerland are mostly the same at every broker, except stamp duty and the paperwork. A Swiss broker charges stamp duty but hands you a ready-made eTax statement. A foreign broker skips the stamp duty, and you do the tax list yourself.

Is there a capital gains tax on shares in Switzerland?

No. Under Swiss tax law, capital gains on private assets are tax-free, at federal and cantonal level. You can buy a share, sell it a week or ten years later for a profit, and owe nothing on the gain. There's no holding period that makes a gain tax-free, because it's tax-free from day one.

The flip side: losses aren't deductible either. If you sell at a loss, you can't use it to lower your taxable income. For a buy-and-hold investor, that's a fair trade. For someone who trades a lot, there's a catch, and it's called the professional securities dealer.

When does the tax office see you as a professional trader?

If the tax office classifies you as a professional securities dealer (gewerbsmässiger Wertschriftenhändler), your gains become taxable income. The ESTV's Circular No. 36 (German) lists five criteria. If you meet all five, the tax office assumes private asset management, and your gains stay tax-free:

1. You hold the securities you sell for at least 6 months.
2. Your yearly trading volume (all purchases plus all sales) is at most 5 times your securities and cash at the start of the year.
3. Your capital gains are less than 50% of your net income.
4. You don't invest with borrowed money, or your taxable investment income is higher than the interest on that debt.
5. You use derivatives (options, for example) only to hedge your own positions.

Missing one criterion doesn't make you a professional automatically. The tax office then looks at your whole situation, case by case. A typical ETF investor who buys every month and rarely sells is far from these limits.

How much is stamp duty on shares in Switzerland?

Swiss stamp duty on securities (Umsatzabgabe, also called Stempelsteuer) is 0.075% on Swiss securities and 0.15% on foreign securities, per trade, on the purchase or sale price. The federal law sets 0.15% and 0.3%, but the ESTV explains (German) that the Swiss securities dealer owes half of it for each party to the trade. As a private investor, you pay your half.

A quick example: you buy CHF 5,000 of an Irish-domiciled ETF at a Swiss broker. That's a foreign security, so you pay CHF 7.50 in stamp duty, on top of the commission. Sell it later and you pay again. The same CHF 5,000 in a Swiss share costs CHF 3.75.

Who doesn't charge it? Only Swiss securities dealers collect stamp duty, so foreign brokers like Interactive Brokers, DEGIRO and Trading 212 don't charge it. New issues (except foreign fund units), options and money-market paper are also exempt. In our data, all seven Swiss brokers we compare charge it: Saxo, Swissquote, PostFinance, UBS, Cornèrtrader, Yuh and neon.

How are dividends taxed? Income tax and the 35% withholding tax

Dividends are taxed as income, at federal, cantonal and municipal level, at your marginal tax rate. It doesn't matter whether the dividend comes from a Swiss or a foreign company, or which broker you use. You declare every dividend in the securities list (Wertschriftenverzeichnis) of your tax return.

Before you even see a Swiss dividend, 35% is gone: that's the Swiss withholding tax (Verrechnungssteuer). It isn't a cost, it's a deposit. The Confederation holds it until you declare the dividend. Investors who declare their dividends correctly get it back in full, as a refund or as a credit against their tax bill.

How do you reclaim the Swiss withholding tax?

You don't need a special form. You list the Swiss dividend in your securities list, with the gross amount and the 35% withheld, and the canton refunds or offsets it, as ch.ch explains. A Swiss broker's eTax statement fills this in for you. At a foreign broker, you enter each Swiss dividend yourself.

If you forget to declare a dividend, you can lose the refund. On CHF 1,000 of Swiss dividends, that's CHF 350 gone for good, which is a pricey way to skip a line in your tax return.

Which dividends are tax-free in Switzerland?

Distributions from capital contribution reserves (KER) are tax-free for private investors. The ESTV's Circular No. 29c confirms that repayments from these reserves are subject to neither income tax nor the Swiss withholding tax. Several Swiss companies pay part of their dividend this way. Your eTax statement or the company's dividend notice shows which part is KER.

There's a limit for SIX-listed companies: they must pay out at least as much in taxable dividends as they pay from KER (as long as they still have other reserves). So in practice, a KER distribution usually covers at most half of the payout from a listed company.

US withholding tax on shares: W-8BEN and the DA-1 form

US dividends get hit by US withholding tax. With the W-8BEN form, the US takes 15% instead of 30% under the Swiss-US double taxation treaty. At a foreign broker like Interactive Brokers, you sign the W-8BEN online when you open your account. Skip it and you pay double.

Why does a Swiss bank keep an extra 15%?

Swiss banks acting as US Qualified Intermediaries must withhold an additional 15% on US dividends for Swiss residents, according to the ESTV's instructions on US dividends. So at a Swiss broker, a USD 100 dividend can arrive as USD 70. You get the extra 15% back through your tax return (form R-US 164, which many cantons have built into the DA-1 form). It's a timing cost, not a lost one.

When is the DA-1 form worth it?

The remaining 15% US tax can be credited against your Swiss tax with the DA-1 form. Two rules matter, both from the ESTV's DA-1 instructions:

• The CHF 100 rule. If your non-reclaimable foreign taxes total CHF 100 or less in a year, there's no credit. You declare the dividends net of the foreign tax instead.
• The cap. The credit can't exceed the Swiss tax due on that same income.

At 15%, CHF 100 of US tax means about CHF 667 of US dividends a year. At a 2% dividend yield, that's roughly CHF 33,000 in US shares. Below that, the DA-1 isn't worth your evening.

How does wealth tax work on shares?

Your shares count toward your wealth tax, at their tax value on 31 December. That's usually the year-end price published in the federal ICTax course list. In Switzerland, wealth tax is purely cantonal and municipal, and the rates differ a lot between cantons. Every canton has a tax-free allowance, so a small portfolio may not trigger any wealth tax at all.

To give you an idea from the ESTV's 2026 tax data: a single person with CHF 500,000 of net wealth pays CHF 639 a year in Zürich, CHF 1,638 in Geneva and CHF 1,611 in Lugano. To check your own municipality, use our Swiss tax map.

What does your broker do for your tax return?

This is where your broker choice really shows. A Swiss broker sends you an eTax statement (Steuerauszug) each year. You import it into your tax software, and it fills in every position, its tax value, every dividend and the withholding tax to reclaim. A foreign broker gives you an annual report, and you build the securities list yourself.

Without an eTax statement, you look up each position in the federal ICTax course list and enter the year-end value and every dividend by hand. With five ETFs, that's an hour. With 30 single stocks, it's a weekend. For Interactive Brokers, third-party services create an eTax statement for about CHF 45 to 50.

Worked example: a CHF 50,000 portfolio for one year

Let's put real numbers on it. This is a simulation with simple assumptions, so you can see where each tax lands.

Assumptions: CHF 20,000 in Swiss shares, CHF 10,000 in US shares and CHF 20,000 in an Irish-domiciled world ETF that distributes. A 2% dividend yield gives CHF 400, CHF 200 and CHF 400 of dividends: CHF 1,000 in total. During the year, you buy CHF 5,000 of the ETF four times.

You compare Saxo (Swiss broker, free eTax statement) with Interactive Brokers (foreign broker). For the Swiss broker, we assume the bank withholds the extra 15% on US dividends, as Swiss banks acting as US Qualified Intermediaries must.

The US tax stays at CHF 30, which is below the CHF 100 threshold, so there's no DA-1 credit. You declare the US dividends at CHF 170 instead of CHF 200. Your taxable dividend income is then CHF 970, at both brokers.

What do you pay in income tax on those CHF 970? It depends on your income and municipality. For a single person earning between CHF 100,000 and CHF 150,000 (no church tax), the ESTV's 2026 tax data shows that each extra franc of income costs on average about 24 centimes in Zürich, 26 in Lugano and 29 in Geneva.

That puts the tax on your dividends at roughly CHF 234 in Zürich, CHF 256 in Lugano and CHF 282 in Geneva. It's an estimate: salaries are reduced by social contributions before tax and dividends aren't, so the real figure can be a little higher.

And wealth tax? Our ESTV data starts at CHF 500,000 of wealth, so we can't give you an exact figure for a CHF 50,000 portfolio on its own. Depending on your canton's allowance and your other assets, it can be zero. Income and wealth tax are the same at both brokers.

The bottom line: the broker changes about CHF 30 a year here (stamp duty), plus your time on the tax return. That's exactly the trade-off in our best brokers ranking.

Are ETFs taxed differently from shares in Switzerland?

Mostly no. ETF distributions are taxed as income, and your ETFs count toward wealth tax, just like shares. Two details differ. First, accumulating ETFs don't pay you anything, but the reinvested income is still taxable each year. The ICTax list shows the amount. Second, the fund's domicile decides the withholding tax.

A Swiss-domiciled ETF deducts the 35% Swiss withholding tax, which you get back. An Irish-domiciled ETF has no Swiss withholding tax, but the fund itself pays US tax on its US dividends, and you can't reclaim that. US-domiciled ETFs can also expose your estate to US estate tax.
