Airdrops, rewards, mining, staking: how to classify crypto income for tax purposes

Basics

In Switzerland, crypto income means inflows from mining, staking, airdrops, lending and liquidity mining. It is taxable at its CHF value at the time of receipt, while pure price gains in private assets remain tax-free. Pure price movements are not the same as a taxable inflow. For natural persons holding private assets, capital gains from the sale of payment tokens are generally tax-free, whereas ongoing income, compensation or free allocations can be taxable.

This distinction is the starting point for a correct tax return.^1,3,4

In addition, the term reward is too imprecise for tax purposes to be treated simply as a category of its own. Whether an inflow counts as income from movable assets, as earned income or as income from self-employment depends on the economic function of the transaction, the token type and your role in the system. FINMA distinguishes between payment tokens, utility tokens and asset tokens; this functional view is also helpful for tax classification.^1,6,7

In practice, this means you should declare by type of inflow, not by platform name. A swap is not the same as a staking reward. An airdrop is not the same as a purchase. And running your own validator is not the same as merely delegating coins to a staking pool.^1,5,6

Mining

In mining, payment tokens are not bought on an exchange but received as compensation for the mining effort. The ESTV classifies this compensation as taxable income.

The Canton of Zurich also states that, for natural persons, mining by providing computing power for a fee leads to taxable income from self-employment.^1,3

For you, the first tax-relevant point is therefore not the later price development of the newly created coins, but the inflow of the coins itself. The decisive value is the value at the time of receipt, converted into Swiss francs.^1,4

Typical mistake: only considering mining income when the coins are sold later. For tax purposes, however, relevance starts earlier. The inflow is income; a later sale also raises the question of whether the coins are held as private or business assets and whether a later gain is tax-free or taxable.^1,3,4

Staking

The ESTV has described its staking practice comparatively clearly. If you make tokens available to a staking pool, the compensation paid generally qualifies as income from movable assets. The taxable amount is the value at the time of receipt, converted into Swiss francs.^1,5

The situation is different if you do not merely delegate but act as a validator yourself. In that case, it must also be examined whether you are self-employed. This distinction matters in practice because it can change how income, costs and later gains are classified.^1,4,6

For documentation, it is therefore not enough to know the annualized yield of a platform. You need a list of the rewards actually credited, with date, time or value date, token quantity and CHF value. Especially with frequent payouts, tax data can otherwise quickly become incomplete or distorted.^1,4,8

Airdrops

For classic free allocations of payment tokens, the ESTV treats airdrops as taxable income from movable assets, valued at market value at the time of allocation. For tax purposes, an airdrop is therefore precisely not the same as a tax-free private capital gain.^1,5

At the same time, you should not treat airdrops schematically. The tax information published by the SSK in cooperation with the ESTV distinguishes between different types of airdrops and expressly points out that the tax consequences depend on the token type and the issuance conditions.

A holder airdrop, a bounty airdrop or a project-related allocation after certain actions can have different economic effects.⁶

In practice, this means: first check why you received the token. Was the allocation a simple free distribution to existing holders, compensation for a specific action or part of a more complex token model?

Only then can you decide properly whether the inflow is investment income, earned income or, in a special case, something else.^1,6,7

Rewards and DeFi

Many platforms simply speak of rewards. For tax purposes, that is too broad. The term can cover staking income, lending income, liquidity mining inflows, governance token allocations or other benefits.

The Canton of Graubünden expressly lists mining, staking, liquidity mining and lending as crypto income that must be declared, provided there is no self-employment.⁴

DeFi calls for particular caution. In Switzerland, there is still no simple blanket rule under which every DeFi inflow is automatically treated the same way.

Professional practice therefore rightly looks at the economic function of each individual transaction: is it ongoing income, compensation for liquidity provided, a mere reallocation of assets or the allocation of a new token?^4,8

This is where one of the most common mistakes happens. Many taxpayers only declare the year-end balance of their wallet and overlook the many tax-relevant inflows that arose during the year. You should therefore never derive DeFi income from the closing balance, but record it transaction by transaction.^4,8

Where official federal practice does not describe every individual case in detail, a cautious and well-documented declaration is the most robust solution. The more complex the protocol, the more important a traceable explanation of your tax classification becomes.^1,4,8
