Zero Capital Gains Tax on Bitcoin in Switzerland

I work in the crypto self-custody space and I file my own Swiss tax return every year. None of what follows is tax advice. It is what I would tell a friend who just moved to Zurich and bought their first Bitcoin.

TL;DR

Bitcoin remains capital-gains tax-free for Swiss private investors in 2026 (DBG Art. 16 Abs. 3 + StHG Art. 7 Abs. 4 lit. b). You still pay wealth tax on the CHF year-end value. The rate depends on your canton and commune. The professional-trader test can reclassify your gains as taxable income. CARF crypto reporting does not apply in 2026, and the SIF says it cannot start before 1 January 2027. Selbstanzeige under DBG Art. 175 Abs. 3 remains the cleanup path while that timeline shifts.

What 2026 changed for Swiss Bitcoin holders

Private investors pay zero capital gains tax when they sell at a profit. That rule is written in DBG Art. 16 Abs. 3 and StHG Art. 7 Abs. 4 lit. b, and the ESTV has applied it to payment tokens since its working paper on cryptocurrencies of 14 December 2021.

In 2026 the tax rule stayed put and the reporting timeline moved. Parliament passed the amended AEOI Act on 26 September 2025 (SIF questions and answers). At its meeting of 3 and 4 November 2025, the National Council's WAK-N suspended its consultation of the crypto-asset partner-state decree. The SIF explanatory report of 26 November 2025, published with the Federal Council's implementing ordinance, states that crypto data can be exchanged from 1 January 2027 at the earliest and that no CARF duties apply in 2026. The amended CRS (CRS 2.0) took effect on 1 January 2026, and it already treats certain crypto assets, e-money and central-bank digital currencies as financial assets. Only the separate crypto reporting framework (CARF, in Swiss law the Melderahmen für Kryptowerte) is on hold.

Crypto-asset reporting needs Parliament to approve the list of partner states (business 25.052). On 28 September 2026 the National Council voted not to take up that decree, and it went back to the Council of States committee. Until both chambers agree, there is no partner list and no crypto data exchange.

The compliance window is still open. If your declarations are not clean, you have more time than the original 2026 start date suggested.

Zero capital gains for private investors

Switzerland does not levy capital gains tax on the sale of movable private assets (DBG Art. 16 Abs. 3 + StHG Art. 7 Abs. 4 lit. b). Swiss tax law classifies Bitcoin as movable private property. If you qualify as a private investor, every franc of gain from selling Bitcoin is yours, at the federal level and at every cantonal level.

There is no holding-period requirement, no exemption limit, no threshold above which gains become taxable. The framework treats a CHF 5,000 gain and a CHF 500,000 gain identically.

The ESTV (Eidgenössische Steuerverwaltung) working paper on cryptocurrencies of 14 December 2021 states the same: buying and selling payment tokens is treated like transactions in conventional currencies, and gains in private assets are tax-free capital gains. The same rule covers shares and bonds, and it exempts private investors only.

You need no special structure or tax ruling for this, because the statute grants the exemption itself.

The five-indicator professional-trader test

The zero-CGT rule applies to private investors only. If the ESTV or your cantonal tax authority reclassifies you as a professional trader (gewerbsmässiger Händler), your gains become taxable as ordinary income at the ordinary federal, cantonal and communal income-tax rates, plus AHV contributions.

The ESTV applies five criteria from ESTV Kreisschreiben Nr. 36 by analogy to crypto (ESTV working paper of 14 December 2021, footnote 7). You must satisfy all five cumulatively to stay safely on the private side. Falling on the wrong side of any single one opens a case-by-case review. KS Nr. 36 Ziff. 4.3 sets out the Federal Court case law behind that review, including decision 2C_868/2008.

1. Holding period at least six months

Selling Bitcoin consistently within six months of purchase signals short-term trading rather than long-term investment. Frequent trades and short holding periods are the main indicator, though KS Nr. 36 Ziff. 4.3.2 notes that in some circumstances a single transaction can be enough.

2. Transaction volume not more than five times the start-of-period portfolio

KS Nr. 36 caps annual transaction volume at five times the Wertschriften- und Guthabenbestand at the start of the tax period. Volume means the sum of all purchase prices and sale proceeds in the calendar year. There is no absolute transaction count. The ratio to your starting portfolio is what matters.

3. No debt financing, unless the taxable income from the assets exceeds the related debt interest

Trading with borrowed money (margin accounts, Bitcoin-backed loans used to fund further purchases, leveraged instruments) breaks this criterion unless the taxable income from the assets exceeds the related debt interest. KS Nr. 36 Ziff. 4.3.2, following the Federal Court (2C_868/2008), puts transaction volume and debt financing in the foreground of the assessment. You control leverage more directly than holding period or trade frequency, so I would avoid it.

4. Trading income not required to cover living expenses

KS Nr. 36 presumes you do not depend on trading gains when your realised gains stay below 50% of your net income for the tax period. Gains of 50% or more fail the criterion. This catches people off guard in strong bull markets when a portfolio appreciates faster than an annual salary.

5. Derivatives used only to hedge existing positions

Buying or selling derivatives (especially options) must stay limited to hedging your own positions. KS Nr. 36 Ziff. 4.3.2 treats derivative use beyond hedging, at a large volume relative to your total wealth, as speculative and a sign of professional trading.

The ESTV weighs all the circumstances together. You must satisfy all five cumulatively to stay safely private. Falling outside any single one opens a case-by-case review. Keep records of your activity, so you can show your holding pattern if a tax authority ever asks.

Income events that are taxed

The capital gains exemption covers appreciation in the value of your Bitcoin. It does not cover income derived from Bitcoin-related activity. The following items are taxable regardless of your investor classification (ESTV working paper of 14 December 2021, Ziff. 2.2.2).

Staking rewards

Rewards from a staking pool or platform are income from movable assets (DBG Art. 20 Abs. 1) at the CHF value on receipt. If you run your own validator, the ESTV checks whether the activity is self-employment (DBG Art. 18 Abs. 1).

Mining

Bitcoin mining rewards are taxable income in every case (DBG Art. 16 Abs. 1). If the general criteria of self-employment are met, the rewards are self-employment income (DBG Art. 18 Abs. 1), taxable as Erwerbseinkommen, and they trigger AHV/IV/EO contributions at the full 10.0% combined rate (8.1% AHV + 1.4% IV + 0.5% EO), with a CHF 530 annual minimum contribution. A sliding scale applies below CHF 60,500 of income (AHV Merkblatt 2.02). For the tax mechanics of running miners as heaters in a Swiss home, see home Bitcoin mining in 2026.

Salary or fees paid in Bitcoin

If your employer pays you in Bitcoin, or a client pays you in Bitcoin for professional services, that payment is taxable employment or self-employment income. The value is the CHF equivalent at the time of receipt. You cannot receive Bitcoin compensation and defer the tax event. You owe tax when you receive the asset.

Airdrops

Airdrops count as taxable income from movable assets at the time of receipt, valued at the CHF market price when the tokens are allocated to you (ESTV working paper, Ziff. 2.2.2). "I didn't ask for it" is not a recognised defence under Swiss tax law. If it had a discernible market value, declare it.

What CARF does and does not do in 2026

The OECD Crypto-Asset Reporting Framework (CARF) does not touch your underlying tax liability. It changes visibility, and the Swiss start date has moved since the Federal Council first planned it.

What CARF requires when it applies

Under Section II of the CARF rules, crypto service providers (exchanges, brokers, custodians) report, for each user:

• Name, address, country of residence, tax identification number and date of birth
• Per crypto-asset, the aggregate amounts paid and received, units and number of transactions, split into purchases, sales, swaps and transfers
• Transfers to wallet addresses the provider does not know to belong to another provider or a bank

Why CARF does not apply in 2026

Parliament passed the amended AEOI Act on 26 September 2025. The National Council's WAK-N suspended its consultation of the partner-state decree at its meeting of 3 and 4 November 2025, citing major partner markets that delayed their own start and reopened interpretation questions at the OECD (WAK-N press release of 4 November 2025). The SIF explanatory report of 26 November 2025 confirms that no CARF duties apply in 2026. The amended CRS (CRS 2.0) took effect on 1 January 2026, and it already treats certain crypto assets, e-money and central-bank digital currencies as financial assets (SIF FAQ on the crypto AEOI). Only the separate crypto reporting framework is on hold.

Reporting starts no earlier than 1 January 2027 (SIF FAQ). Providers report a calendar year's data in the following year (CARF Section II G), so the first exchange would come in 2028 at the earliest. The Federal Council's original plan was entry into force in 2026 and a first exchange in 2027. On 28 September 2026 the National Council voted not to take up the partner-state decree (25.052), so the decree is back with the Council of States committee and no start date is fixed.

What the data exchange exposes

When CARF crypto reporting goes live, Swiss exchanges will transmit your reportable transaction data to the ESTV, which will then share it with foreign tax authorities under AEOI. It applies to service providers, not to self-custody wallets. Transfers from a provider to your own wallet are part of what the provider reports, so the trail exists.

If your declarations are clean, nothing changes for you. If you have gaps, use the delay to correct them before the data starts to flow.

The voluntary disclosure window

If your past declarations were incomplete (Bitcoin held but not declared for wealth tax, staking income not reported), straflose Selbstanzeige under DBG Art. 175 Abs. 3 offers a regularisation path. ZH explains its procedure in ZStB 241a.1.

The terms: you pay back taxes owed plus interest (DBG Art. 151), for up to ten years back (DBG Art. 152). In return, the first-time disclosure avoids criminal prosecution for Steuerhinterziehung, provided no tax authority yet knows the facts and you cooperate without reservation. Each further disclosure still triggers a fine, cut to one fifth of the evaded tax (DBG Art. 175 Abs. 4).

The structural constraint: Selbstanzeige requires that no tax authority yet knows the hidden facts. In my reading, once CARF reporting delivers your data to the tax office, that condition can fail. The window is open today because the exchange has not started, and I would not count on it staying open.

Wealth tax you owe every year

The zero-CGT rule covers profits from selling. It does not exempt you from Switzerland's Vermögenssteuer (wealth tax).

The cantons levy Vermögenssteuer annually on your total net assets. Your Bitcoin holdings count as taxable assets regardless of whether you have realised any gains, including coins held in self-custody on a hardware wallet, not only those on Swiss exchanges.

How to declare

Valuation date: December 31 each year. The ESTV publishes an official Kursliste with year-end CHF valuations for major digital assets including Bitcoin (ESTV ICTax / Kursliste). Use the ESTV published figure, not an exchange price from a random moment on December 31.

Where on the tax return: Your Bitcoin holdings go in the Wertschriften und Guthaben (securities and assets) section of your cantonal tax declaration, the same section where you would declare shares or investment funds.

Which canton: Your canton of domicile on December 31 determines which cantonal rules apply. The cantons set their own wealth tax tariffs (StHG Art. 1 Abs. 3). Compare your own numbers with the ESTV tax calculator. For tax period 2025 the personal deduction for a single filer ranges from none (Bern, Ticino, Vaud, Neuchâtel) to CHF 204,000 (Zug) (ESTV Steuermäppchen, persönlicher Abzug Vermögenssteuer). A canton without a deduction can still exempt small fortunes: Bern levies no wealth tax when the rate-determining wealth is below CHF 100,000 (StG BE Art. 65 Abs. 3). Check your canton.

Non-declaration is punishable. Intentionally omitting assets from your wealth declaration is Steuerhinterziehung (tax evasion, DBG Art. 175 Abs. 1). If you have held Bitcoin and not declared it, use the Selbstanzeige process described above while the window is open.

DeFi and wrapped Bitcoin sit in a grey zone

Swiss federal tax law has not issued specific rulings on every edge case in decentralised finance. If you have been active in DeFi using wrapped Bitcoin (WBTC) or Bitcoin Layer 2 protocols that interface with Ethereum-based protocols, the tax treatment is unclear.

The general principles that apply, absent specific rulings:

• Wrapped tokens (WBTC). In my reading, wrapping is a swap of one private asset for another. For a private investor the swap itself produces no taxable gain (DBG Art. 16 Abs. 3), but keep a record of every wrap and unwrap.
• Liquidity provision and yield from DeFi protocols. Interest or fee income from providing liquidity is likely taxable as Vermögensertrag. No official Swiss ruling exists, but the income-type logic matches the ESTV working paper's treatment of staking rewards.
• Frequent DeFi activity. High-frequency interaction with DeFi protocols (repeated swaps, yield farming, position management) raises your risk of triggering the professional-trader indicators.

The Swiss Blockchain Federation's Digital Assets Tax Framework Review Switzerland 2026/02 (Version 1.3e, March 2026) notes that the distinction remains difficult and that cantonal practice differs. It is a trade-body summary, not an official position paper. For anything beyond straightforward hold and sell, take conservative positions and get professional advice.

Records for your Swiss return

You can file a Swiss tax return for straightforward Bitcoin holding without specialised software. What you need is your 31 December balance per wallet and exchange, the ESTV Kursliste rate, and the receipt-date CHF value of any staking, mining or airdrop income. If you use a crypto tax tool to compile those, check its year-end figure against the Kursliste before you file. For anything beyond buy, hold and sell, a Swiss-licensed Steuerberater is the safer route.

What applies to you

Zero CGT still stands compliance does not

Switzerland has not changed its capital gains tax framework. Private investors still pay zero.

What changed is the visibility timeline. CARF crypto reporting does not apply in 2026, and the SIF puts the earliest start at 1 January 2027, with a first exchange no earlier than 2028. Parliament still has to approve the partner states, and the National Council voted against taking up that decree on 28 September 2026. Once the exchange runs, Swiss exchanges will transmit your reportable transaction data to the ESTV. Holdings never declared for wealth tax become discoverable then. Selbstanzeige stays available until that point.

Three actions if you hold Bitcoin in Switzerland in 2026.

1. Confirm your past wealth tax declarations are complete. If they are not, initiate Selbstanzeige under DBG Art. 175 Abs. 3 this year. The CARF delay widens the runway. It does not erase the obligation.
2. Prepare your 2025 Bitcoin transaction history now. Your 2025 return needs the ESTV Kursliste value at 31 December 2025 (BTC = CHF 69,571.99) and any staking, mining, or airdrop income received during the year.
3. Check your transaction pattern against the five-indicator test. If you have been trading actively, assess whether your activity crosses into gewerbsmässiger Händler territory.

Zero CGT remains one of the strongest arguments for holding Bitcoin in Switzerland. That advantage only holds if your wealth-tax declarations are complete.

Per-canton Bitcoin tax variations

The federal capital gains exemption applies uniformly across Switzerland. Cantonal wealth tax brackets, declaration codes, and Bitcoin-specific guidance vary by canton. Drill down to your canton:

• Bitcoin Tax in Zurich. From tax year 2026 the statutory einfache Staatssteuer runs from 0 to 3‰ on net wealth above the CHF 81,000 (single) / CHF 161,000 (couple) zero band per Zurich Steuergesetz § 47, multiplied by the combined Staats- and Gemeindesteuerfuss of 166% to 223% in 2026 depending on commune (City of Zurich 214%), plus church tax where applicable (current Gemeindesteuerfüsse). Operative tariff guidance: ZStB 34.1.

More cantons will follow.
