A new binding answer supports that if you stake through a protocol or staking service that does not convert your staked tokens into other tokens, then it does not trigger tax liability.

In the case, some tokens were “locked” via Nexo in a way where the said tokens were “locked” at Nexo in exchange for a dividend payment and after a period “unlocked” again for the user – in other words, there was no transaction where the involved tokens were exchanged for other tokens.

This practice is in line with the authorities’ basic approach to crypto taxation, that tax liability (only) is imposed on speculative transactions with crypto assets. That was not the case here, where ownership did not change and the involved tokens did not change form. This corresponds to certain staking protocols, where staked tokens are simply “locked” in a protocol.

It may look different if using staking protocols where staking involves the exchange of staked tokens.
