What is Coinbase cbETH?

cbETH (Coinbase Wrapped Staked ETH) is Coinbase's liquid staking token. When you stake ETH via Coinbase, you receive cbETH that accumulates staking rewards while remaining liquid for use in DeFi.

Wrapped Staked ETH

cbETH is an ERC-20 token representing your staked ETH plus accumulated rewards. Unlike rebasing tokens such as stETH, cbETH rises in price relative to ETH as rewards accumulate.

Coinbase Custody

The underlying ETH is managed by Coinbase validators. cbETH can be transferred on-chain, used in DeFi protocols, or exchanged back to ETH via Coinbase or decentralized exchanges.

Staking Rewards

Coinbase charges a 25% commission on staking rewards. The net yield (approximately 2.5-3% APY) is reflected in the rising value of cbETH relative to ETH.

How does Cryptotax treat your cbETH for tax?

Key tax considerations

  • ①
    Converting ETH to cbETH may be taxable.

    In Belgium, converting ETH to cbETH may be seen as an exchange and therefore a realization. The capital gain on your ETH would then become taxable. This is a grey area, so consult an adviser.

  • ②
    Yield is taxable as movable income.

    The increase in cbETH's value relative to ETH represents staking rewards. When you sell or unwrap, this income is realized and taxable at 30% withholding tax on movable income.

  • ③
    Selling cbETH means realizing a capital gain.

    If you sell cbETH for EUR, ETH or other crypto, you realize both the accumulated yield and any exchange gain. Both may be taxable depending on your investor profile.

  • ④
    Using cbETH in DeFi.

    Using cbETH as collateral is not a taxable event. Tax liability arises only on liquidation or sale. Additional yield from DeFi protocols is, however, directly taxable.

Frequently asked questions about Coinbase tax in Belgium

Do I need to declare my Coinbase account?

For now, you do not need to report a Coinbase account to the National Bank of Belgium because it is not a bank account. This may change with new regulation. You must, however, declare your crypto gains.

How do I track cbETH yield?

cbETH rises in value relative to ETH. Cryptotax calculates the implicit yield by tracking the exchange rate over time and converting it to EUR value at realization.

What about DAC8 from 2026 onwards?

From 2026, crypto exchanges such as Coinbase must share customer data with EU tax authorities. Make sure your historical transactions are reported correctly now.

Can I bridge cbETH to an L2?

Yes, cbETH also exists on Base (Coinbase's L2). Bridging is not a taxable event. Cryptotax detects cross-chain transfers and keeps your cost basis intact.
