Switzerland capital gains tax in 2026: the key figures

Is this guide for you?

Read on if you…

• invest privately in shares, funds or crypto as a Swiss resident and want to keep your gains tax-free;
• trade actively, use leverage or earn most of your income from markets and worry about the professional-trader label;
• own or plan to sell Swiss property, or hold shares in your own company and plan an exit.

Probably not your case if you…

• are not Swiss tax resident and hold no Swiss real estate – your home country's rules apply;
• are looking for the company-level treatment of asset sales – see corporate income taxes in Switzerland.

Why are private capital gains tax-free in Switzerland?

Article 16 paragraph 3 of the Federal Act on Direct Federal Tax (DBG) states that capital gains on private movable assets are tax-free; the cantonal harmonisation law says the same. The trade-off is an annual wealth tax: a small percentage on what you own, not a large one on what you gain.

Three things follow:

• Losses are not deductible. A tax-free gain and a non-deductible loss are two sides of the same coin.
• Income from the asset is still taxed. Dividends, bond interest, fund distributions and staking rewards are ordinary income. The 35% withholding tax on Swiss dividends is refunded when you declare them.
• Accumulating funds are not a loophole. The FTA publishes the taxable income portion of each fund in its price list; you pay tax on that portion even if nothing was distributed. Only the genuine capital gains part stays tax-free.

Honestly? For most buy-and-hold investors, that is the whole story. The rest is about the exceptions.

When do your gains become taxable income?

The professional-trader test

The FTA's Circular No. 36 gives a safe harbour. You are definitely a private investor if, in the tax year, you:

1. held each security for at least six months before selling;
2. traded no more than five times your portfolio value as at 1 January;
3. made capital gains below 50% of your net income;
4. used no debt to finance your positions;
5. used derivatives only to hedge existing positions.

Fail one or more and the tax office weighs frequency, leverage and whether trading replaces a salary. A professional securities dealer pays income tax at all three levels plus about 10% AHV on all gains; losses become deductible and carry forward seven years. The same test applies to crypto – see cryptocurrency taxes in Switzerland.

Business assets

Assets of a sole proprietorship or partnership are business assets. Gains on them – equipment, goodwill, business property, a client list – are taxed as income plus AHV, including when you move an asset to private use. If you give up self-employment at 55 or older, or through disability, the liquidation gain is taxed separately at one fifth of the ordinary federal tariff, minimum 2% (Article 37b DBG).

Share sales requalified as dividends

Two rules turn a tax-free share sale into taxable dividend income:

• Indirect partial liquidation (Article 20a DBG): you sell at least 20% of a company to a buyer who holds the shares as business assets (typically another company), and within five years the company distributes reserves that existed at the sale and were not needed for operations. The distributed part becomes taxable income for you.
• Transposition: you sell shares in a company you control to another company you own at least 50% of, for a price above their nominal value. The excess is taxable.

Founders selling to a holding or a strategic buyer should get a ruling first. Our guide on legal forms of business in Switzerland explains why the share sale is otherwise the most tax-efficient exit.

Employee shares and options

Employer shares are taxed as salary at grant, with a 6% discount per year of blocking period up to ten years; options at exercise. Once taxed, the shares are private assets and later gains are tax-free.

How is real estate taxed when you sell?

Property is the big exception. Private real estate gains escape federal tax but are taxed by the canton where the property sits, under the real estate gains tax (Grundstückgewinnsteuer). Tariffs differ, but the pattern is the same:

A Zurich flat sold for a CHF 200,000 gain after twelve years attracts a base tax of roughly CHF 70,000, reduced by about 28% for the holding period to around CHF 50,000. Sell after 18 months and a 25% surcharge applies instead.

Monistic cantons (Zurich, Bern, both Basel, Schwyz, Nidwalden, Uri, Ticino, Jura) tax all real estate gains under this tax; dualistic cantons tax business real estate gains as ordinary income instead. Foreign property gains are taxed where the property is and exempt in Switzerland, with progression.

Do non-residents pay Swiss capital gains tax?

Rarely. If you live abroad and sell Swiss shares, funds or crypto, Switzerland taxes nothing. If you sell Swiss real estate, the cantonal gains tax applies as for residents. Shares in a company whose assets are mainly Swiss real estate are treated as real estate in some cantons and under many treaties.

Leaving Switzerland triggers no exit tax on your portfolio, because there was never a tax to defer. The one timing point: if you are a professional trader or own business assets, moving abroad can be treated as a transfer out of Swiss taxation, with the hidden reserves taxed on departure. Details are in ceasing your tax residency in Switzerland. Arriving with unrealised gains, as covered in obtaining tax residency in Switzerland, needs no step-up: the later gain is tax-free anyway.

How do you keep your gains on the tax-free side?

1. Keep leverage out of your portfolio. Margin trading is the single most visible professional-trader signal.
2. Hold for six months or more where you can, and keep annual turnover below five times your portfolio value.
3. Keep your main income elsewhere. Gains below half your net income rarely attract attention.
4. Plan company exits with a ruling. Indirect partial liquidation and transposition are avoidable with the right buyer structure and distribution policy.
5. Time property sales. Each extra year of holding cuts the cantonal gains tax; selling in year two instead of year one removes a surcharge.
6. Declare everything. Wealth tax and the 35% withholding tax refund depend on full declaration. Our guide on personal tax deductions and benefits in Switzerland lists what else to claim.

Common mistakes (and what they cost)

• Trading on margin as a side hustle. You lose the safe harbour; gains become income plus about 10% AHV, often a 30%–45% combined rate instead of 0%.
• Selling your company to a holding you own without a ruling. Transposition turns the price above nominal value into taxable dividend income.
• Selling property in year one or two. Zurich adds 50% or 25% to the gains tax; other cantons apply similar surcharges.
• Ignoring the taxable income portion of accumulating ETFs. The FTA price list shows it; omitting it is under-declaration with back taxes and interest.
• Assuming "tax-free" means "no paperwork". Unexplained jumps in declared wealth trigger questions about undeclared income.

Frequently asked questions

Is there capital gains tax in Switzerland in 2026?

Not on private movable assets. Gains on shares, bonds, funds and crypto held privately are tax-free at federal, cantonal and municipal level. Switzerland taxes net wealth every year instead. Gains on real estate are taxed by the cantons, and gains made as a professional trader or on business assets are taxed as income with social security contributions.

How much is real estate gains tax in Switzerland?

It depends on the canton, the size of the gain and how long you held the property. Zurich, for example, applies a progressive tariff from 10% to 40%, adds 50% for sales within one year and 25% within two, and cuts the tax by up to 50% after 20 years. Costs, commissions and value-adding renovations reduce the taxable gain.

When does the Swiss tax office treat me as a professional trader?

When your activity looks like a business: frequent trades, short holding periods, debt financing, speculative derivatives and gains that make up a large share of your income. You are safe if you hold for six months or more, trade under five times your portfolio value a year, make gains below half your net income, use no leverage and hedge only.

Are ETF and fund gains taxable in Switzerland?

The price gain on your fund units is tax-free. The income the fund earns – dividends and interest, whether distributed or accumulated – is taxable, using the taxable income portion published in the Federal Tax Administration's price list. Choose funds with Swiss tax reporting so the capital gains part is separated; otherwise the whole distribution can be treated as income.

Do I pay tax on selling shares in my own company?

Normally no, if you hold them privately and sell to an independent buyer. Two exceptions apply: selling at least 20% to a company that then distributes old reserves within five years (indirect partial liquidation) and selling to your own holding company above nominal value (transposition). Both turn part of the price into taxable dividend income, so get a ruling before signing.

Does Switzerland have an exit tax on capital gains?

No. Because private capital gains are not taxed in Switzerland, there is nothing to tax when you leave. Your portfolio moves with you untaxed, and your new country of residence may apply its own rules, sometimes with a step-up to market value on arrival. Only business assets and professional traders can face taxation of hidden reserves on departure.
