What is ENS?

Ethereum Name Service (ENS) is the decentralized naming system for Ethereum. With a .eth domain you can replace your wallet address with a readable name such as "jannssen.eth", making transfers simpler and safer.

.eth Domains

ENS domains are NFTs that you register for an annual fee. Short names (3-4 characters) cost more. You pay in ETH and receive an NFT that represents ownership of your domain.

Renewals

ENS domains must be renewed every year. If you do not renew, your domain expires and someone else can register it. Renewal fees are also paid in ETH.

ENS Token

The ENS governance token was airdropped to early users. ENS token holders can vote on protocol upgrades and treasury allocations through the ENS DAO.

How does Cryptotax treat your ENS activity for tax?

Key tax considerations

  • ①
    Registration is an expense, not an investment.

    The ETH you pay for domain registration is treated as a service fee, comparable to registering a traditional domain name. This is an expense, not a taxable event.

  • ②
    Paying ETH for registration = a realization.

    When you spend ETH on registration, you realize the capital gain on that ETH. The difference between the EUR value at the moment of payment and your cost basis is taxable.

  • ③
    An ENS airdrop is taxable income.

    The ENS token airdrop is taxable at the moment of claim. The EUR value of the received tokens counts as movable income (30%).

  • ④
    A domain sale is a capital gain.

    If you sell your ENS domain NFT for more than your registration cost, the difference is a taxable capital gain. Premium domains can rise significantly in value.
