Capital gains tax in Switzerland: What US expats need to know
The short answer to whether there is a capital gains tax in Switzerland: only on real estate and professional trading gains.
Switzerland generally does not tax private capital gains on movable assets. Profits on shares, ETFs, and crypto are usually tax-free at the federal, cantonal, and municipal levels. Real estate is the exception: gains on Swiss property are taxed by the canton where the property sits, with rates that depend on holding period and location.
If you're a US citizen or green card holder, none of this erases your IRS duty. You still report worldwide capital gains on your US return, regardless of how Switzerland treats them. The numbers below reflect the 2025 tax year, which you'll file in 2026.
For the broader picture, our overview of US tax preparation in Switzerland walks through filing mechanics end to end, and our guide to the tax implications of foreign investing explains how foreign holdings interact with IRS rules.
Does Switzerland have a capital gains tax?
Only on a narrow slice of assets. Under Article 16, paragraph 3 of the Federal Act on Direct Federal Tax (DBG/LIFD), gains from selling private movable assets are exempt from federal, cantonal, and municipal income tax. Real estate is the exception, and so is anything you sell as a business or professional trader.
In practice, there are three buckets to keep straight:
- Private movable assets (shares, ETFs, bonds, crypto, funds): gains are usually tax-free in Switzerland.
- Real estate located in Switzerland: gains are taxed separately at the cantonal and municipal level, regardless of where you live.
- Business or professional trading: gains become ordinary self-employment income, taxed at federal and cantonal rates plus social contributions.
The line between the first and third bucket is what catches most active investors off guard, and we cover the reclassification criteria further down.
The short answer to whether there is a capital gains tax in Switzerland: only on real estate and professional trading gains.
Private movable assets escape Swiss tax entirely; Swiss real estate is always taxed by the canton; and US citizens owe US tax on all of it, regardless.
| Asset type | Swiss treatment | US treatment |
|---|---|---|
| Shares, ETFs, mutual funds (private) | Tax-free | Taxable: short-term at ordinary rates, long-term at 0%, 15%, or 20% |
| Bonds (price gain only) | Tax-free | Taxable as capital gain; interest taxed as ordinary income |
| Cryptocurrency (private holdings) | Generally tax-free on sale | Taxable as property; every sale/exchange reported |
| Swiss real estate | Taxed by the canton (separate gains tax) | Taxable; foreign tax credit may apply |
| Business or professional trading gains | Ordinary income + social contributions | Ordinary income or capital gain, depending on classification |
On the US side, long-term gains are taxed at 0%, 15%, or 20% depending on your taxable income, while short-term gains follow your ordinary income bracket.
Our walkthrough of capital gains and losses for US taxpayers breaks down the holding-period rules and how losses offset gains.
Switzerland's capital gains tax rate: the quick answer
There is no single capital gains tax rate in Switzerland. The figure you actually pay depends entirely on what you sold and whether you sold it as a private investor or in a business capacity.
Three quick rules cover most situations:
- Private stocks, ETFs, and crypto: 0% in Switzerland for private investors.
- Swiss real estate: canton-specific schedules, so the rate depends on the canton, the gain, and the holding period.
- US tax on the same transactions: 0%, 15%, or 20% for long-term gains held over one year; ordinary income rates for anything held one year or less.
US gains and losses are reported on Schedule D and Form 8949. For Swiss property specifically, the rate calculation gets layered with cantonal surcharges and reductions, which is something our guide on capital gains tax on foreign property breaks down.
Capital gains tax on stocks and shares in Switzerland
Switzerland's capital gains tax on stocks for private investors is 0%. Under Art. 16(3) DBG, price gains from selling shares, ETFs, and mutual funds held as private assets are exempt from federal, cantonal, and municipal income tax. That makes Switzerland one of the more favorable jurisdictions in Europe for buy-and-hold equity investors.
TFX client scenario: A US expat in Zurich buys shares for CHF 5,000 and sells them three years later for CHF 7,500. The CHF 2,500 gain is tax-free in Switzerland. On the US return, the same gain is a long-term capital gain reported on Form 8949 and Schedule D, taxed at 0%, 15%, or 20% depending on the client's total US taxable income.
The Swiss exemption only covers the price gain. Three things still attract Swiss tax on the same portfolio:
- Dividends and interest are taxed as ordinary income at federal, cantonal, and municipal rates.
- Swiss domestic law generally applies 35% withholding tax to Swiss-source dividends and certain investment income. Under the US-Switzerland treaty, eligible US residents can usually reduce Swiss dividend withholding to 15% for portfolio holdings or 5% for qualifying direct corporate stakes, typically through the Swiss refund process. Swiss interest is often not subject to withholding, but exceptions apply.
- The shares themselves count toward your taxable wealth, and the wealth-tax rate depends on the canton and commune.
The favorable Swiss capital gains tax on shares assumes you stay on the private-investor side of the line. Cross that line, and the same gains become ordinary self-employment income.
Private investor vs. professional securities trader
Switzerland's 0% rate only applies to private investors. If the Federal Tax Administration reclassifies you as a professional securities trader, your gains stop being tax-free and become self-employment income, taxed at federal and cantonal rates, and Swiss social contributions generally total 10.0% on higher self-employment income, with a degressive scale below CHF 60,500.
The five "safe harbor" criteria sit in Federal Tax Administration Circular No. 36 (Kreisschreiben Nr. 36, dated 27 July 2012). Meet all five, and you're definitely private; miss any one, and the tax office can look at the full picture of your trading activity.
Private crypto disposals are generally treated similarly to private securities disposals, but active trading, leverage, or commercial-scale activity can lead to professional trader treatment by analogy to the securities-trader criteria.
To stay safely classified under Switzerland's capital gains tax private investors' rules, you need to satisfy all of the following:
- Holding period: every security sold was held for at least 6 months.
- Transaction volume: your total annual turnover (purchases plus sales) does not exceed 5 times your securities holdings at the start of the year.
- Income share: realized capital gains make up less than 50% of your net income, meaning you're not living off trading profits.
- No leverage: you don't use debt (margin loans, Lombard credit, mortgages) to finance your securities purchases.
- Derivatives only for hedging: options and futures are used to protect your existing portfolio, not as a separate trading strategy.
For US expats, professional classification in Switzerland doesn't change anything on the US side: gains are still reported as capital gains on your US return regardless of how Switzerland labels you.
Our overview of US expat taxes covers how Swiss income types map onto your 1040.
Switzerland's capital gains tax on crypto
Capital gains in Switzerland on crypto follow the same rule as other private movable assets for private holders: 0%. Sell Bitcoin, Ether, or any other token at a profit, and the gain is exempt at the federal, cantonal, and municipal level, as long as you meet the same Circular No. 36 safe-harbor criteria that apply to stock traders.
The exemption only covers the price gain on sale. Two other Swiss tax rules apply to your crypto:
- Wealth tax: your holdings must be declared at their December 31 market value and are taxed annually by your canton. The Federal Tax Administration publishes reference rates for major cryptocurrencies each year.
- Income-type rewards: staking rewards, mining income, lending interest, airdrops, and hard forks are taxed as ordinary income at the market value when received, not as capital gains.
Active trading (frequent volume, leverage, derivatives outside hedging) flips the analysis. If the tax office classifies you as a professional crypto trader, your gains become self-employment income subject to ordinary tax plus social contributions.
The capital gains tax in Switzerland for cryptocurrency lining up at 0% is irrelevant for your US filings. The IRS treats every crypto sale, swap, or spend as a reportable digital asset transaction, and the IRS guidance clarifies how cost basis and holding periods work. Every Swiss-tax-free disposal is still a US capital gain or loss reported on Form 8949 and Schedule D.
Switzerland's capital gains tax on property
Swiss capital gains tax on property is taxed separately from regular income, by the canton (and often the municipality) where the property sits. There is no federal real estate gains tax: the cantons hold this competence in full, and rates follow canton-specific schedules depending on the gain and the holding period.
The taxable gain is calculated roughly as:
Sale price − acquisition cost − eligible improvements − transaction costs = taxable gain
Acquisition cost is what the previous owner paid; eligible improvements include value-adding renovations (not routine maintenance); transaction costs include notary fees, real estate agent commissions, and certain documented expenses. The exact list of deductible items varies by canton and is set out in cantonal law.
Holding period is the second lever, and it matters enormously. Most cantons apply a surcharge for short-term resales (often 25% to 50% on top of the base rate if you sell within 1 to 2 years) and grant a discount that grows with each additional year of ownership.
In Zurich, for example, the discount reaches 50% after 20 years; in Bern it caps at 35 years; in other cantons the schedule looks different.
TFX client scenario: A US expat in Zurich buys an apartment for CHF 800,000 and sells it for CHF 1,000,000 (CHF 200,000 gain). After 5 years of ownership, the cantonal property gains tax is approximately CHF 65,930. After 20 years, the same gain produces roughly CHF 34,700 in tax, because the long-ownership discount is at its maximum.
On the US side, the sale of foreign real estate is a reportable capital gain or loss on Form 8949 and Schedule D, and the gain on a primary residence may qualify for the $250,000 / $500,000 exclusion under IRC §121 if you meet the ownership and use tests.
Swiss property-gains tax may be creditable on Form 1116 if it qualifies as a foreign income tax under IRS rules, but not every property-related levy is creditable.
Our guide on foreign property tax for US expats walks through in detail.
Capital gains tax in Switzerland for non-residents
If you've moved out of Switzerland but kept Swiss assets, the rule splits along asset type: movable assets generally fall outside Swiss tax, but Swiss real estate stays fully taxable in the canton where it sits.
Three rules cover most cases:
- Private securities (shares, ETFs, crypto): non-residents owe no Swiss tax on the sale, the same exemption that applies to residents, unless the activity rises to professional trading or qualifies as Swiss-source business income.
- Swiss real estate: gains remain taxable by the canton, regardless of where the seller now lives. Cantons typically require a security deposit or withholding at sale to ensure collection.
- Swiss domestic law levies a 35% anticipatory tax on Swiss-source payments, though treaty relief can reduce or eliminate withholding on qualifying dividends and interest for US residents.
For US citizens and green card holders, leaving Switzerland doesn't end your US filing duty. The US taxes its citizens on worldwide income regardless of where they live, the principle behind citizenship-based taxation.
Every Swiss-tax-free sale of stocks or crypto is still a US capital gain, and every sale of Swiss property is a US capital gain in addition to the cantonal property gains tax.
The relevant US forms are Form 8949 and Schedule D for the gain itself, Form 1116 for the foreign tax credit on Swiss property gains tax, plus FBAR and Form 8938 if your foreign accounts cross the reporting thresholds for taxpayers living abroad.
Switzerland's capital gains tax by canton
There is no single Swiss property gains tax rate because each canton sets its own. Five variables drive the final bill:
- The canton itself: each of the 26 cantons has its own statute and rate schedule.
- The municipality: many cantons add a communal multiplier on top of the cantonal base.
- The size of the gain: most cantons use a progressive scale, so larger gains hit higher brackets.
- The holding period: short-term sales attract surcharges (often 25% to 50%); long-term ownership earns discounts that grow each year.
- The property type: rules can differ for primary residences, secondary homes, and commercial property, including deferral options when sale proceeds are reinvested in a new primary home.
Two practical examples make the spread concrete. In Zurich, the tax office grants discounts of 5% after 5 years of ownership, 11% after 7 years, and a maximum 50% after 20 years; properties resold within one year face a 50% surcharge. In Ticino, the effective rate runs from about 4% (over 30 years' holding) to 31% (under 1 year).
The Federal Tax Administration runs a Swiss tax calculator covering income and wealth tax across cantons, and the federal portal lists all cantonal and communal tax types with links to each canton's tax office.
What US expats in Switzerland must still report to the IRS
Switzerland's 0% rate on private capital gains has no effect on your US filing duties. As a US citizen or green card holder, you report worldwide capital gains, income, and foreign accounts on the same forms whether you live in Zurich or Houston.
Five reporting obligations cover most US expats with Swiss investments:
- Form 1040 with Schedule D and Form 8949: every capital gain or loss is reported here, including sales that are tax-free in Switzerland. Long-term gains (held over one year) qualify for the 0%, 15%, or 20% preferential rates; short-term gains follow ordinary income rates.
- Digital asset question on Form 1040: every return now requires you to answer the digital asset question; if you sold, swapped, spent, or received crypto during the year, the answer is "yes."
- FBAR (FinCEN Form 114): required if the aggregate value of your foreign financial accounts exceeded $10,000 at any point during the year. Filed separately from your 1040, through the FinCEN BSA E-Filing portal.
- Form 8938 (FATCA): required if your specified foreign financial assets exceed the relevant threshold. For expats filing single, that's $200,000 on the last day of the year or $300,000 at any point during the year; for joint filers abroad, $400,000 / $600,000. Our breakdown of Form 8938 thresholds and assets covered explains exactly what counts.
- Form 1116 (Foreign Tax Credit): used to claim credit for any Swiss tax actually paid (mainly property gains tax, dividend withholding, or income tax on rental income). The credit offsets US tax on the same income, dollar for dollar, up to the US tax attributable to that foreign income.
Can the US-Switzerland tax treaty reduce double taxation?
Yes, but only partially. The US-Switzerland income tax treaty has been in force since Jan. 1, 1998, and the 2009 protocol took effect on Jan. 1, 2020.
The treaty can reduce Swiss withholding on Swiss-source dividends paid to eligible US residents and provides mechanisms to coordinate taxation of certain income types.
The treaty's main practical effects for individuals:
- Dividend withholding: Swiss anticipatory tax is 35% on investment income at source, but the US-Switzerland treaty generally caps Swiss tax on dividends at 15% for portfolio holdings and 5% for a qualifying direct corporate stake; treaty relief for Swiss-source dividends is usually claimed through the Swiss refund process.
- Interest and royalties: reduced or eliminated withholding under the relevant articles.
- Government service, pensions, and social security: allocated between the two countries under specific treaty articles.
- Tie-breaker rules: determine residency when an individual could be treated as a resident of both countries.
What the treaty does not do: erase the "saving clause." The US reserves the right to tax its citizens and green card holders as if the treaty did not exist for most income items. So a US citizen living in Zurich still files Form 1040, still reports the sale of Swiss shares on Schedule D, and still pays US capital gains tax on the disposal even though Switzerland charges nothing.
Where Swiss tax does apply (most commonly on rental income, dividend income net of refund, and property gains tax), Form 1116, Foreign Tax Credit, is the standard tool to avoid being taxed twice on the same income.
Our US-Switzerland tax treaty guide walks through the articles most relevant to expats and the practical mechanics of claiming benefits.
Practical examples
Three common scenarios show how the Swiss and US sides line up on the same transaction.
TFX client scenario #1 – Swiss shares: A US expat in Geneva bought 200 shares of Nestlé in 2019 for CHF 18,000 and sold them in 2025 for CHF 26,000 (CHF 8,000 gain).
- Swiss result: CHF 0 tax. Private investor exemption under Art. 16(3) DBG.
- US result: Long-term capital gain reported on Form 8949 and Schedule D. Converted to USD at the relevant exchange rates, the gain is taxed at 0%, 15%, or 20% depending on total US taxable income. No foreign tax credit available (no Swiss tax was paid).
TFX client scenario #2 – Bitcoin held in a Swiss wallet: A US expat in Zug bought 1.5 BTC in 2021 for CHF 45,000 and sold all of it in 2025 for CHF 90,000 (CHF 45,000 gain).
- Swiss result: CHF 0 tax on the disposal (private investor, safe harbor met). The BTC was included in annual wealth tax filings at the December 31 ESTV reference rate while held.
- US result: Long-term capital gain reported on Form 8949 with the digital asset box checked on Form 1040. USD basis and USD proceeds determine the gain; FX movement can produce a different USD gain than the CHF figure suggests.
TFX client scenario #3 – Swiss apartment: A US expat in Zurich bought an apartment in 2010 for CHF 800,000 and sold it in 2025 for CHF 1,000,000 (CHF 200,000 gain) after 15 years of ownership.
- Swiss result: Cantonal property gains tax in Zurich, reduced by the long-ownership discount that applies at the 15-year mark. Approximately CHF 45,000 to CHF 55,000, depending on deductible improvements and transaction costs.
- US result: Long-term capital gain reported on Schedule D. If the apartment was the primary residence and the §121 ownership-and-use tests are met, up to $250,000 of gain (single) or $500,000 (joint) is excluded. Any remaining gain is taxed at long-term rates. Swiss property-gains tax may be creditable on Form 1116 if it qualifies as a foreign income tax under IRS rules.
Records to keep before you sell investments or property
The Swiss side wants documentation in CHF; the US side wants USD figures tied to specific dates. The IRS generally requires you to keep records that support items on your return for at least three years, longer for property and investments.
Keep the following before any sale:
- Purchase and sale documentation: original purchase contract, sale contract, dates of acquisition and disposal.
- Broker and exchange statements: full transaction history showing trade dates, quantities, and prices for every security and crypto position.
- FX rates: USD/CHF rate on the date of every acquisition and every disposal (Treasury or Federal Reserve published rates are acceptable for US filings).
- Swiss tax statements: annual securities and wealth tax statements from your bank, plus any cantonal assessments related to property.
- Renovation and improvement invoices: itemized invoices for capital improvements to real estate, separated from routine maintenance (the two are treated differently for Swiss property gains tax deductions).
- Property closing documents: notary deeds, transfer tax receipts, broker commission invoices, and any cantonal property gains tax notices.
- Crypto transaction history: complete export from every exchange and wallet, including transfers between your own wallets (needed to reconstruct cost basis).
FAQ
Only on a narrow set of assets. Private gains on movable assets (shares, ETFs, crypto, bonds) are exempt at the federal, cantonal, and municipal levels under Art. 16(3) DBG. Real estate located in Switzerland is taxed by the canton where it sits, and business or professional trading gains are taxed as ordinary income.
There is no single rate. Private investors pay 0% on stocks, ETFs, and crypto. Swiss real estate gains are taxed under canton-specific schedules, depending on the gain and the holding period. Professional traders pay ordinary income tax plus social contributions (generally 10.0%, degressive at lower income levels).
For private investors who meet the Circular No. 36 safe harbor criteria (6-month minimum holding period, transaction volume under 5x portfolio value, no leverage, gains under 50% of net income, derivatives only for hedging), the rate is 0%. Cross any of those lines and the tax office can reclassify you as a professional trader. Private crypto disposals are generally treated similarly to private securities disposals, but active trading, leverage, or commercial-scale activity can lead to professional trader treatment by analogy to the securities-trader criteria.
The gain on sale is tax-free for private holders, the same treatment as stocks. Your crypto holdings are still subject to annual wealth tax at the December 31 market value, and any income-type rewards (staking, mining, lending interest, airdrops) are taxed as ordinary income at the value received.
Generally, no on private securities and crypto. But Swiss real estate gains remain taxable by the canton where the property sits, regardless of where the seller lives, and Swiss domestic law levies a 35% anticipatory tax on Swiss-source dividends and interest, though treaty relief can reduce or eliminate withholding on qualifying payments for US residents.
Yes. The US taxes its citizens and green card holders on worldwide income regardless of residence, so every Swiss-tax-free disposal is still a US capital gain reported on Form 8949 and Schedule D. Where Swiss tax is paid (mainly on property gains, rental income, or dividends), Form 1116 lets you credit it against US tax on the same income.
The capital gains tax on Swiss property is set by the canton and often the municipality where the property is located. There is no federal real estate gains tax. The taxable gain is the sale price minus acquisition cost, eligible improvements, and transaction costs, and rates depend on the canton, holding period, and gain size. US owners report the same sale on Schedule D and may claim the §121 primary residence exclusion ($250,000 single / $500,000 joint) if the ownership and use tests are met.
