The declaration of cryptocurrencies and foreign assets has become a major issue for Swiss taxpayers. The Federal Tax Administration (FTA) now has powerful tools to detect undeclared assets, thanks to the Automatic Exchange of Information (AEOI) with over 100 countries.

Cryptocurrencies -- Declaration rules: all cryptocurrencies (Bitcoin, Ethereum, stablecoins, tokens) must be declared as wealth assets at their value on December 31, using the rate published by the FTA. If the FTA does not publish a rate for a specific token, the value on the reference exchange platform applies.

Tax regime for crypto gains: for private investors, capital gains are tax-exempt (as with stocks). For professional traders, gains are taxed as self-employment income with AHV/AVS contributions. The criteria for professional qualification include high volume, transaction frequency, use of leverage, and debt financing.

Taxable crypto income (even for private investors): staking rewards are taxable as wealth income, mining constitutes self-employment income, lending (DeFi) generates taxable wealth income, airdrops are taxable as income at the value upon receipt, and payments in crypto constitute taxable employment income.

Foreign assets: all bank accounts, securities portfolios, life insurance policies, and pension assets held abroad must be declared as wealth and income. The AEOI allows Swiss tax authorities to verify the compliance of declarations against information transmitted by foreign financial institutions.

Our experts precisely calculate the value of your crypto portfolio, identify taxable income, and ensure your declaration is complete and compliant with FTA requirements.

Frequently asked questions

How do I declare my cryptocurrencies for tax purposes in Switzerland?
You must declare all your cryptocurrencies in the 'Securities and capital investments' section at their value as of . The FTA publishes official rates for the main cryptocurrencies. For unlisted tokens, use the exchange platform rate. Capital gains for private investors are tax-exempt, but staking/mining income is taxable.
Is there a risk of reassessment for undeclared crypto?
Yes. With the Automatic Exchange of Information (AEOI) and growing cooperation between exchange platforms and tax authorities, the risk of detection increases every year. A tax reassessment can go back 10 years with late-payment interest and fines of up to 3 times the evaded tax. A voluntary disclosure (once in a lifetime) allows you to avoid fines.
How does the flat tax work in Neuchâtel?
Since , the Canton of Neuchâtel has applied a flat rate of approximately 12.66% on taxable income at the cantonal level, with no progressivity. This means that every franc of taxable income is taxed at the same rate, regardless of the total amount. Municipalities then add their own coefficient. The direct federal tax remains progressive. This system particularly benefits high-income taxpayers, while low incomes are protected by social deductions and allowances.
Which are the lowest-taxed municipalities in Neuchâtel?
Neuchâtel municipalities apply different tax coefficients that influence the overall tax burden. Among the most advantageous municipalities are La Grande Béroche, Val-de-Ruz, and Milvignes. The municipal coefficient can vary significantly and represent a difference of several hundred or even thousands of francs per year. It is therefore wise to take municipal taxation into account when choosing your place of residence in the canton.
