Why most crypto investors
are exposed right now
HMRC and the IRS have both been clear: crypto is taxable. But the tools most people rely on, and the accountants most people use, are getting it wrong in ways that will come back to hurt you.
Koinly's number is wrong
Crypto tax tools miss cost basis errors, misclassify DeFi transactions, and can't handle wallet-to-wallet transfers correctly. The output looks official. It usually isn't. We have corrected Koinly reports on almost every client we have onboarded.
Your accountant doesn't understand crypto
General accountants file crypto gains incorrectly the majority of the time. They don't know how HMRC treats staking rewards versus how the IRS treats them, or how DeFi disposals differ from simple trades. Each jurisdiction has its own rules. We know both.
HMRC and the IRS are both watching
HMRC has data-sharing agreements with Coinbase, Kraken, Binance, and others. The IRS has sent thousands of warning letters to crypto holders and requires Form 8949 for every disposal. Both authorities already have your data. Your filing needs to match it.

Do you need to file?
Answer four quick questions and get an instant answer about your UK crypto tax obligation.
HMRC nudge letters and compliance notices have deadlines. Ignoring them results in automatic penalties, and HMRC treats non-response as confirmation of undisclosed gains. The longer you leave it, the higher the penalty rate and the more interest accumulates.
We deal with HMRC correspondence regularly. A free discovery call is the fastest way to understand exactly what the letter means, what your exposure is, and what needs to happen next.
With gains over £50,000, the difference between a correctly reconciled return and an inaccurate one can be significant. Overstated gains from missing cost basis, misclassified wallet transfers, or unrecorded losses are common — and each one means paying tax on money you did not actually make.
The Self Assessment deadline for 2025/26 is 31 January 2027. Reconciliation must be completed first.
Your gains are above the £3,000 annual CGT allowance, which means they must be reported to HMRC via Self Assessment. The deadline for the 2025/26 tax year is 31 January 2027.
Before filing, your transactions need to be reconciled under HMRC's Section 104 pooling rules. Software reports are often inaccurate — particularly for wallets, DeFi, and staking activity. A free discovery call will tell you exactly what is involved.
The annual CGT allowance is £3,000 for 2025/26. If your net gains are genuinely below this, you may have no tax to pay. However, if you are registered for Self Assessment, you may still need to declare the gains even if no tax is owed.
The risk is that software reports are often inaccurate. Missing cost basis can make your gains appear lower than they are, meaning you could unknowingly underreport. A quick check is worth doing before you assume everything is fine.
Staking rewards, mining proceeds, and airdrop income are treated as miscellaneous income under HMRC rules — not capital gains. This means the £3,000 CGT allowance does not apply. The income is taxed at your marginal income tax rate in the year it was received.
When you later sell those coins, you will also have a separate CGT event on the disposal. Two tax obligations on the same asset. A discovery call will clarify exactly how this applies to your situation.
If you held crypto without selling, swapping, or receiving any income from it, there is generally no taxable event and therefore no filing obligation for this year. Unrealised gains are not taxable until you dispose of the asset.
If you are already registered for Self Assessment for other reasons, it is worth confirming with an accountant. And if your situation changes, come back and check again.

This is an estimate only. It does not account for your full income tax picture, mixed-rate scenarios, carried-forward losses, or the bed-and-breakfasting rules. Use it as a starting point, not a final figure. A proper assessment requires full reconciliation of your transaction history.
