Why now

The window is closing

The automatic exchange of information on crypto assets (AEOI/CARF) has been approved. What is still open is the timing and the list of countries — not whether your data will reach the tax authorities. While nothing is flowing, the route of a penalty-free voluntary disclosure is still open to you. That is exactly why now is the right moment to get your portfolio in order.

Approved, not yet started

  • Parliament has approved the AEOI on crypto assets
  • The start date has not yet been fixed
  • Still open: which partner states the data will be exchanged with

What the exchange will bring

  • Crypto service providers are to report customer data
  • Swiss clients of foreign exchanges will be covered too
  • The exchange between tax authorities follows

The records disappear first

  • Exchanges delete old trading data or shut down entirely
  • Exports and API access often reach back only a few years
  • The later you reconstruct, the more work it takes

FAQ

Frequently asked questions about crypto & taxes

Yes. Your holdings are subject to cantonal wealth tax and must be declared every year as of 31 Dec. at market value in the list of securities. A wallet statement, for example, serves as evidence. Simply holding, however, does not trigger income tax.
On private assets, in principle yes: private capital gains are tax-free as long as you do not qualify as a professional trader. The flip side: losses are not deductible.
It does not come down to a single figure. FTA Circular Letter No. 36 (KS 36) describes a safe harbor: anyone meeting all five conditions, among them a minimum holding period, a capped transaction volume and no debt financing, counts as managing private assets. If one of them is not met, that does not automatically mean professional trading; the overall picture then decides. Practice applies these criteria to cryptocurrencies by analogy. Where you stand is something we look at against your actual figures.
Staking rewards are investment income, valued at the time of receipt; airdrops are taxable income when they are allocated. Mining income is always taxable income; whether it additionally amounts to self-employment depends on the individual case. For lending there is no published FTA practice. The classification and the correct recording are our job.
In most cases yes. We rebuild the history from what exists: exchange exports, API access, wallet addresses via the blockchain and bank statements for deposits and withdrawals. Where a gap remains, we work with a plausible assumption, label it as such and document it. Bring what you have — we will tell you what is missing.
The FTA price list (ictax.admin.ch) as of year-end is decisive. If a coin is not listed there, the year-end price of your trading platform applies, or as a last resort the purchase price in CHF.
For private assets, no: losses only reduce your taxable wealth as of the reference date. They would only be deductible if your holdings counted as business assets — which in turn would make all gains taxable.
With a first-time voluntary disclosure the fine is waived, provided the legal requirements are met; you owe back taxes for a maximum of 10 years plus default interest. Important: quietly adding the coins to your next return is not enough, and the disclosure only remains penalty-free as long as the authorities do not already know about it. How the procedure works in detail is set out on our page on voluntary disclosure and back taxes. We guide you through the entire process.
Not at the moment. Switzerland has approved the automatic exchange of information on crypto assets (CARF), but when it takes effect, and with which countries, has not been finally settled. The direction is set; the timetable can still change. If you have legacy issues, the best time to clean them up is while no data is flowing. We will look at where your exchanges stand in the initial consultation.
Yes. Anyone holding cryptocurrencies makes decisions continuously: a change of exchange, a new staking product, a larger sale. Those decisions have tax consequences, often only visible a year later. In the annual engagement Taxiva 365 your tax affairs sit with the same tax expert all year, including the declaration and your representation before the tax office.
