How does Switzerland distinguish between private and professional crypto trading for tax purposes?

The key tax divide in Swiss crypto taxation is between private investor and professional trader status. Private investors — people who buy and hold crypto as part of personal wealth management without using leverage, trading very frequently, or treating it as a primary income source — pay no income tax on gains. Their holdings are simply subject to annual wealth tax.

Professional traders are reclassified by the cantonal tax authority as running a business activity. All gains become ordinary income subject to income tax at marginal rates plus AHV/AVS contributions. The FTA and cantonal authorities apply a multi-factor test adapted from the securities trading circular to crypto. Relevant indicators include: holding periods under six months, gross transactions exceeding five times portfolio value in a year, use of borrowed funds for purchases, and reliance on trading profits for livelihood.

Crypto received as payment for work or services, mining rewards, staking income, liquidity provision fees, and referral bonuses are treated as ordinary income in all cases — regardless of investor vs trader status — at the market value when received. Losses from professional trading can offset other business income; losses for private investors do not create a deductible loss since gains were never taxable to begin with.
