What Triggers a Taxable Event
Understanding which events trigger tax obligations is the foundation of crypto tax compliance. Not all crypto activity is taxable — transfers between your own wallets are generally not taxable events. But disposals, income events, and most active transactions are taxable in most jurisdictions.
| Event | Tax Type | Taxable in US/UK? | Notes |
|---|---|---|---|
| Crypto sold for fiat | Capital gain/loss | Yes | Most common taxable event |
| Crypto-to-crypto swap | Capital gain/loss | Yes | Both US and UK treat as disposal |
| Staking rewards received | Ordinary income | Yes | US: IRS Rev. Rul. 2023-14; UK: misc. income |
| Mining income | Ordinary income | Yes | FMV at time of receipt; deductible expenses apply |
| Airdrops received | Ordinary income | Yes (if freely receivable) | UK: misc. income; some defer until disposal |
| Hard fork tokens | Ordinary income (US) | Yes | FMV at time of receipt |
| DeFi yield farming | Ordinary income | Yes | Each reward event is income |
| NFT sale | Capital gain | Yes | US: potentially collectibles rate (28%) |
| Transfer between own wallets | None | No | No change of ownership |
| Crypto gift received | Varies | US: none at receipt; UK: none at receipt | Donor may have gain on gifting |

DeFi Tax Challenges
DeFi transactions create the most complex tax scenarios in the crypto space. Unlike simple trading, DeFi interactions involve multi-step transactions, token transformations, and continuous income events that don't fit neatly into traditional tax categories.
- Liquidity pool deposits: Providing tokens to a DEX liquidity pool and receiving LP tokens is treated as a disposal of the input tokens in the US and UK (taxable event). The LP tokens received have a cost basis equal to the FMV of the input tokens at the time of the transaction.
- LP withdrawals: When removing liquidity, the LP tokens are disposed of (at FMV at withdrawal time) and underlying tokens are received. Any difference from original cost basis is a gain or loss. Impermanent loss is realised at this point.
- Yield farming: Rewards tokens received from yield farming protocols are ordinary income at FMV at time of receipt. Each distribution event creates a new taxable income amount and a new cost basis for the received tokens.
- Wrapped tokens: Wrapping ETH to wETH may or may not be a taxable event depending on jurisdiction. UK HMRC has indicated that wrapping is generally not a disposal if the economic substance doesn't change; the US position is less clear.
- Cross-chain bridges: Most bridges are treated as wallet transfers (non-taxable) if the same economic asset is moved. Some bridges that involve burning and minting may create disposal arguments.
