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 December 31. 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 do I file my tax return in the Canton of Vaud?

The Vaud tax return can be submitted online through the cantonal tax administration (ACI) portal. You must declare your income, assets, deductions, and attach the required supporting documents in PDF format. The standard deadline is March 15 of each year.

Which are the lowest-taxed municipalities in the Canton of Vaud?

The lowest-taxed municipalities in Vaud are mainly located on the Riviera and in the Nyon district. Among the most tax-advantageous municipalities are Montricher, Essertines-sur-Rolle, and certain municipalities in the Pays-d'Enhaut. The municipal coefficient generally ranges between 54% and 79% of the base cantonal tax. The choice of municipality of residence can represent a difference of several thousand francs on the annual tax bill.

Withholding Tax & TOU

Withholding tax is deducted directly from the salary of B permit, L permit, or cross-border workers. We analyze your situation to file a Subsequent Ordinary Assessment (TOU) request when it is advantageous, which often allows you to recover several thousand francs. Since 2021, the withholding tax reform has expanded TOU eligibility for many taxpayers.

Cross-Border Taxation

Cross-border workers are subject to complex tax rules arising from the double taxation agreements between Switzerland and France. Depending on your canton of employment, you may be taxed at source in Switzerland or only in France. We guide you to optimize your situation and avoid double taxation, taking into account the Franco-Swiss agreement of April 11, 1983 and its amendments.
