The private-investor exemption: no capital gains tax on crypto
Switzerland is one of the most favourable jurisdictions for private crypto investors. For individuals holding cryptocurrency as a private asset — similar to holding shares, gold, or foreign currency — capital gains from selling are not subject to income tax. This applies whether you hold for days or years, and whether your gain is CHF 100 or CHF 100'000.
This exemption is not a special crypto rule — it is the same principle that applies to all private capital gains in Switzerland. If you sell shares, ETFs, or a second home at a profit as a private individual, the gain is generally tax-free. Crypto is treated the same way. The logic is that private capital gains are not considered income but rather a change in the composition of your wealth.
However, this exemption has a critical boundary: it only applies if the tax authority classifies you as a private investor. If you cross into professional trading — through frequency, leverage, or dependence on trading income — the tax treatment changes entirely. The gain becomes taxable business income, and losses become deductible. The Federal Tax Administration has published detailed criteria for this boundary, which we cover in the next section.
Professional trader vs private investor: where the line is drawn
The FTA distinguishes private investors from professional securities dealers using five main criteria. These criteria apply equally to crypto as they do to stocks and other assets. Meeting several of them increases the risk of reclassification.
Criterion one: holding period. Buying and selling the same asset within a short time — especially within six months — suggests trading rather than investing. Holding crypto for longer than one year generally supports private-investor status.
Criterion two: transaction volume. High-frequency trading with many transactions per week or month is a strong indicator of professional activity. Using automated trading bots or scripts compounds this risk.
Criterion three: leverage. Borrowing money to trade (margin trading, futures, derivatives) is a hallmark of professional activity. If you trade crypto with borrowed funds, the tax authority is very likely to classify the gains as business income.
Criterion four: income dependence. If your crypto trading profits are your main source of income — or a significant supplement to your salary — this points toward professional status. A CHF 5'000 gain alongside a CHF 120'000 salary is less concerning than CHF 50'000 in crypto gains with no other income.
Criterion five: use of others' capital. Managing crypto on behalf of family, friends, or clients, or operating a trading pool, is professional activity.
If reclassified as a professional trader, all crypto gains become taxable as ordinary income at your marginal rate, and you may need to register for AHV contributions and potentially VAT. This is a material consequence — anyone trading more than occasionally should document their rationale and consider getting a tax ruling before their first declaration.
Wealth tax: declaring crypto holdings on 31 December
Every Swiss tax resident must declare their worldwide assets as of 31 December for wealth-tax purposes. Cryptocurrency is no exception. The market value of every crypto position — Bitcoin, Ethereum, stablecoins, and any other token — must be included in your annual declaration.
The FTA publishes a yearly list of exchange rates and crypto valuations. For major cryptocurrencies, the value is the CHF equivalent at the year-end rate published by the FTA or a recognised exchange. For tokens not on the official list, you must use a reasonable market valuation — typically the price from a major exchange like Kraken or Binance at midnight on 31 December — and note the source.
Wealth tax rates vary by canton and are typically between 0.1% and 0.5% of net taxable wealth per year. The first CHF 80'000 to CHF 200'000 of net wealth (depending on canton and marital status) is exempt. For most small to medium crypto holders, the wealth-tax impact is modest. For a CHF 100'000 portfolio, the annual wealth tax is typically CHF 100 to CHF 500, depending on the canton.
Stablecoins are treated like any other cryptocurrency — they are part of your taxable wealth. An important nuance: if you hold stablecoins as cash equivalents, their value in CHF is straightforward. For volatile coins, the year-end value can differ significantly from the value on any other day. You cannot use an average price over the year — the tax office wants the 31 December snapshot.
If you hold crypto on a foreign exchange or wallet, you must still declare it. The declaring foreign assets guide covers the broader AEOI and CRS rules that apply to foreign-held wealth.
Staking, mining, airdrops, and other crypto income
While selling crypto at a profit is tax-free for private investors, earning new crypto through staking, mining, airdrops, or lending is treated differently. The FTA considers these activities to generate taxable income.
Staking rewards: when you stake tokens and receive additional tokens as a reward, the market value of the received tokens at the time they are credited is taxable income. If you receive 0.5 ETH from staking when ETH is trading at CHF 3'000, you declare CHF 1'500 of income. If you later sell that 0.5 ETH at CHF 3'500, the CHF 250 gain is tax-free as a private capital gain — but the initial CHF 1'500 was already taxed as income.
Mining: mining income is taxable when the coins are created, valued at their market price at that moment. If mining is your main occupation or involves significant equipment, the tax office may treat it as self-employment, requiring AHV contributions and a business registration.
Airdrops and forks: the tax treatment is less settled. An unsolicited airdrop where you did nothing to earn the tokens may be treated as a tax-free gift or lottery win. An airdrop received for holding or staking another token is more likely to be taxed as income. If you actively participated in a protocol to receive tokens — such as providing liquidity or testing — that is almost certainly taxable income.
Lending and yield farming: interest or yield earned from lending crypto through centralised platforms or DeFi protocols is taxable income in the year it is received. The tax treatment mirrors that of bank interest.
Practical declaration workflow for expats
Step one: as of 31 December each year, record the CHF value of every crypto position. Use the FTA list for major coins and a recognised exchange rate for others. Keep a screenshot or CSV export with the date, token, amount, and exchange rate.
Step two: compile all crypto income received during the year — staking rewards, airdrops you participated in, lending interest, and mining proceeds — with the date of receipt and CHF value at that time. If you use a centralised exchange, download the annual transaction report. If you use on-chain activity, use a tool like Koinly, Blockpit, or CoinTracking to generate a Swiss-compatible report.
Step three: enter crypto holdings in the securities and assets section of your tax return, usually under a category like other assets, cryptocurrencies, or movable wealth. Enter crypto income in the income section. The Swiss tax return filing guide explains the full return process.
Step four: if you are uncertain about your classification — private investor or professional — document your trading frequency, holding periods, and income sources. A proactive discussion with a Swiss crypto tax adviser before filing is much cheaper than a later reclassification.
Remember that Switzerland participates in the automatic exchange of information. If you hold crypto on an exchange in an AEOI-participating country, your tax authority may already know about the account. The declaring foreign assets guide covers the AEOI and CRS rules. Honest and complete declaration is the only defensible approach.
