👮 HMRC is Watching Your Wallet
Think your crypto gains are anonymous? Think again. As of 2026, under the OECD's Crypto-Asset Reporting Framework (CARF), major exchanges like Coinbase and Binance are legally mandated to share user data directly with HMRC. If you sold crypto for a profit and didn't declare it, you are not "investing"—you are committing tax evasion. The penalties are severe.

| Sold Bitcoin? HMRC Knows. |
Many UK investors mistakenly believe that cryptocurrency is considered "gambling" (which is tax-free in the UK). This is categorically false.
HMRC classifies crypto assets as property. However, the complexity lies in determining which tax you owe: Capital Gains Tax (CGT) or Income Tax?
Trading vs. Staking (The Critical Difference)
How you generated the funds determines the tax classification. Misclassifying this income is the fastest way to trigger an HMRC enquiry.
⚠️ The "Staking" Trap:
If you earn yield on your crypto (Staking), HMRC treats that yield as Income, similar to a salary or bank interest.
It is added to your total taxable income for the year. For example, if you earn £60k from your employment and £5k from staking, that £5k effectively pushes you further into the higher rate band and is taxed at 40%.
The "Bed and Breakfast" Rule
Can you sell Bitcoin at a loss to lower your tax bill, then buy it back immediately? No.
Under the "30-Day Rule" (often called Bed and Breakfasting), if you repurchase the same asset within 30 days of selling it, HMRC ignores the sale for Capital Gains Tax purposes. You cannot harvest tax losses using this method. You must wait 31 days or purchase a different asset (e.g., sell Bitcoin, buy Ethereum) to crystallise the loss.
Chief Editor's Verdict (Calculate Before You Spend)
Crypto is no longer the Wild West. Before you spend your Bitcoin profits, you must set aside 20-45% for the taxman to avoid penalties.
Use specialised crypto tax software (such as Koinly or Recape) to generate an accurate tax report. Filing incorrectly is often viewed more negatively by HMRC than late filing.
