Private gains are one part of the position
The Federal Tax Administration says gains and losses from purchases and sales of payment tokens held as private assets are generally tax-free capital gains and non-deductible capital losses. Depending on the nature, scale and financing of transactions, the activity can instead be self-employment. In that case gains are taxable income and properly recorded business losses may be deductible.
Crypto holdings are also subject to cantonal wealth taxation and year-end valuation/reporting. Income and wealth burdens vary by canton and municipality, so there is no single Swiss all-in crypto rate.
Mining, staking and distributions
Mining remuneration is taxable income. Passive staking-pool compensation is generally investment income valued when received; operating as a validator requires a separate self-employment assessment. The federal paper also treats airdrops as taxable investment income at their market value on allocation. Token rights and hybrid arrangements can lead to different classifications.
The relocation trade-off
For a family comparing destinations, the benefit can be the treatment of a genuine private investment gain. The costs include ongoing wealth taxation, valuation evidence and the risk of commercial classification. Zurich’s guidance applies securities-trading practice by analogy; a high-volume, leveraged or organised operation should not assume the same treatment as passive ownership.
Obtain a canton-specific assessment of the activity and holdings before comparing a Swiss outcome with a flat foreign capital-gains percentage. Residence permission, living costs and UK departure conditions remain separate parts of the decision.
