The letters have started. Since 1 January 2026 UK exchanges have been collecting and reporting their users’ transaction data under the Cryptoasset Reporting Framework, with the first reports reaching HMRC in 2027. From then on it can compare what it receives against what people declared. The tax rules did not change at all. What changed is that guessing stopped working.
Most self-employed people who hold crypto have never computed a Section 104 pool. They use an app built for US rules that picks lots, or they treat each coin as its own purchase, or they simply report what the exchange summary says. All three produce a wrong number, and the 30-day rule can move a gain by thousands in either direction. If a client ever paid you in crypto, there is a second problem: that payment was income on the day it landed, and it started a capital gains clock at the same moment.
What’s inside
- Capital gains or income? A decision table covering trading, mining, staking, airdrops and being paid in crypto
- What the exchanges now collect and report, and what a one-to-many letter actually means
- Section 104 pooling worked end to end, plus the same-day rule and the 30-day bed-and-breakfast rule that must be applied first
- The disposals people miss: crypto-to-crypto, spending it, gifting it
- Losses — the four-year claim window, and negligible value claims for dead tokens and collapsed exchanges
- Being paid in crypto: sterling value on receipt is both your income and your acquisition cost
- The return itself: rates, the exempt amount, the disclosure boxes, and the record pack to keep
The templates
A Section 104 pool calculator that carries the running average cost and computes the gain on every disposal, a disposal log, a crypto-income log, and the record pack index HMRC expects you to hold for five years and ten months.
Where to start
The first evening is the decision table: for every way crypto came into your hands, whether the tax is capital gains or income. The second is the pool. You enter every buy, sell, swap and spend into the calculator, the same-day and 30-day rules are applied in the right order, and the running average cost updates itself. By the end you know the gain or loss for the year, what goes in which box on the return, and what to keep for the five years and ten months HMRC can ask for it.
Buying more than one? All ten 2026/27 courses, 262 pages and 44 templates, are £119 against £328 at full price. See the full course list.
Not for you if: you run DeFi liquidity positions, lending protocols or a mining business at scale — the mechanics are flagged in the course but they need an accountant.
Questions people ask before buying
Do I need this if I only bought and never sold?
Probably not yet. Holding is not a taxable event. The moment you sell, swap one token for another, spend crypto, or gift it, you have a disposal and the pooling rules apply. Being paid in crypto for work is income immediately.
Does the calculator handle swaps between tokens?
Yes. A crypto-to-crypto swap is treated as a sale of the first token at market value and a purchase of the second. The sheet records both sides and the new token starts its own pool.
What about DeFi, staking pools and liquidity positions?
The course flags where the mechanics sit and what HMRC has said so far, but those positions need an accountant. If that is most of your activity, this is not the right purchase.
Is it updated when the rules or rates change?
Yes. Every Budget produces a refreshed edition, and anyone who has bought the course gets it free by email.
