eToro & Copy Trading Crypto Tax UK: How HMRC Sees Every Copied Trade

Copy trading lets you mirror another trader's moves automatically — popular on eToro, Bybit, BitGet and others. It feels passive, but for UK tax it absolutely isn't: every trade executed in your account is your trade, with your tax consequences, even though someone else pulled the trigger.

You own every copied trade

When the trader you copy sells ETH for USDC, your account sells ETH for USDC too — and that's a Capital Gains Tax disposal for you, valued in GBP at that moment. A busy copied trader can generate hundreds of disposals a year in your name. HMRC doesn't care that the decisions were automated; the assets and the gains are yours. This is the same principle that applies to trading bots.

Real crypto vs CFDs — check what you actually hold

Platforms differ in what a "crypto position" actually is. If you hold real crypto, the standard rules apply: Section 104 pooling, same-day and 30-day matching, CGT at 18% or 24% above the £3,000 allowance. If the position is a contract for difference (CFD), there's no underlying coin to pool — each closed contract produces its own chargeable gain or loss. The paperwork differs, so check your account type before you file. (Spread betting, where offered, is generally outside CGT — but crypto copy trading is almost never structured as spread betting.)

The pooling headache

If you copy several traders who all trade the same coins, all of that activity merges into your single Section 104 pool per token. Trader A's BTC buys average into the same pool as Trader B's — and the 30-day rule can match Trader A's sale against Trader B's re-purchase days later. Manually untangling this from platform statements is genuinely painful, which is why copy traders under-report more than almost any other group.

Fees and the trader's cut

Spreads, overnight fees on leveraged positions and any profit-share to the copied trader affect your numbers differently: trading fees are allowable costs of the relevant disposals, while account-level charges generally aren't deductible against gains.

Records to keep

Export your full account statement regularly — platforms limit history. You need dates, assets, quantities, GBP values and fees for every copied trade. CryptoLens ingests exchange CSVs, converts USD-quoted trades to GBP at the trade date, builds your pools, and outputs an SA108-ready report.
