Nine reading journeys, each starting from the situation you are actually in.
When HMRC gets in touch
Letters, enquiries, disclosures and what each one actually is. Start here if something has arrived in the post.
- An HMRC nudge letter is not a tax bill
- What happens during an HMRC crypto enquiry
- How to disclose unpaid crypto tax before HMRC finds it
Working out what you owe
Allowances, rates, losses and the mechanics of getting a crypto position onto a return that survives inspection.
- What capital gains tax is and how the bill is actually worked out
- Your capital gains tax allowance for 2026 to 2027
- What you actually pay on crypto gains in 2026 to 2027
DeFi, staking and earning
Where the income and capital line falls once tokens start producing more tokens. The area HMRC guidance covers least well and software handles worst.
- Is your DeFi yield income or capital in HMRC’s eyes
- What HMRC actually says about staking rewards
- Adding liquidity to Uniswap is a taxable disposal
Moving, wrapping and bridging
Which movements are disposals and which are not. Getting this wrong is the most common cause of an inflated gain.
- Do You Pay Tax Moving Crypto Between Wallets? The UK Rules
- Is Wrapping or Bridging Crypto a Disposal? UK Tax Rules
- Moving abroad does not end your UK crypto tax bill
Earning it rather than holding it
Payment in crypto, trading as a business, company structures and the badges of trade that decide which one you are.
- Paid in crypto means income tax before capital gains tax
- The badges of trade decide if HMRC calls you a trader

Gifts, estates and life events
What happens to a portfolio at a gift, a death, a divorce or a move abroad.
- Capital gains tax treats a gift as a sale you were never paid for
- Gifting crypto outside marriage triggers capital gains tax
- What your heirs will owe on crypto they inherit
What the platforms report about you
Exchange reporting, CARF, 1099 forms and what arrives whether you asked for it or not.
- From 2026 HMRC receives your crypto data automatically
- What Coinbase and Binance actually send to HMRC
- Does Revolut Report to HMRC? Crypto on Revolut Explained
Paying less of it, legitimately
Loss harvesting, disposal timing, spouse transfers and the reliefs HMRC actually accepts.
- Ways to pay less crypto tax that HMRC accepts
- How to use crypto losses to cut your capital gains bill
- How to report stolen crypto on a UK or US tax return
Side income and self assessment
Marketplace reporting, trading thresholds, changing accountants and the returns that follow.
- eBay reports your sales to HMRC and most sellers owe nothing
- Vinted sellers rarely owe tax even when Vinted reports them
- Your cashback is almost never taxable and HMRC said so in 1997

Whether this is worth a conversation
The guides handle the rules. Where it stops being a reading job, this is what a conversation covers.
- Something has arrived from HMRC and the right guide is not enough
- Your history spans exchanges and wallets no software imports cleanly
- You have read the guides and the position is still genuinely unclear
If a guide above answers your question in full, take the answer. Most visitors need nothing more, and that is the point of publishing them.
