Binance UK Tax Report for HMRC — Complete 2025/26 Guide

Binance is the world's largest crypto exchange by volume, and a huge share of UK investors hold assets there. The bad news: Binance does not produce an HMRC-ready tax report out of the box. The good news: you can export everything you need in about five minutes, and a specialist UK tool will do the pooling maths for you.

Why Binance itself cannot file your UK tax

Binance operates globally and is not a UK-regulated exchange. It gives you a raw transaction ledger but does not classify activity under the UK's Section 104 pooling rules, does not apply the same-day rule, does not apply the 30-day bed-and-breakfasting rule, and does not convert trades to GBP at historical spot rates. HMRC expects all of that — and expects it expressed in pounds sterling.

Exporting your full Binance history

Log into Binance, open Wallet → Transaction History, and export. There are three separate exports you need for a complete picture: Spot Trade History (every buy and sell), Deposit & Withdrawal history (on-chain transfers in and out), and Distribution history (staking rewards, Launchpool drops, airdrops, card cashback). Binance caps each export to 12 months, so for the full 2025/26 tax year (6 April 2025 to 5 April 2026) you may need to run two windows and merge them. CSV is the most compatible format.

What HMRC expects you to report

Every disposal of a token must be reported with its acquisition cost (pooled), disposal value in GBP, and resulting gain or loss. A disposal includes selling for GBP or any fiat, swapping one token for another (USDT → ETH is a disposal of USDT and acquisition of ETH), using crypto to pay for anything, and gifting to anyone who is not your spouse. Internal transfers between your own Binance wallet and a self-custody wallet are not disposals.

Staking, Launchpool, and card rewards

Binance Earn and Launchpool rewards are taxable as miscellaneous income at the GBP market value on the day you receive them. This is not a capital gain — it is income tax at your marginal rate (20%, 40%, or 45%). When you later sell those tokens, the GBP value at receipt becomes your acquisition cost for the Section 104 pool. Binance card cashback is also income for the same reason.

The 2025/26 rates

After the 30 October 2024 Budget, crypto CGT rates are 18% for basic-rate taxpayers and 24% for higher- and additional-rate. The annual CGT allowance is £3,000. Gains above the allowance are taxed at those rates. Losses are not taxable but must be claimed in Self Assessment to be carried forward against future gains.

Using CryptoLens with your Binance export

Upload the three Binance CSVs to CryptoLens and the calculator applies UK pooling rules automatically, computes every disposal with a full audit trail, handles GBP conversion at historical rates, separates staking income from capital gains, and produces a PDF tax summary aligned with the SA108 supplementary pages. You use that report to complete your 2025/26 Self Assessment, due online by 31 January 2027.
