Introduction: The Crypto Tax Shake-Up Coming in 2026
HMRC is preparing one of the biggest shifts in how crypto assets are reported and taxed in the UK. From 1 April 2026, digital asset platforms — including crypto exchanges, NFT marketplaces, DeFi platforms, and crypto payment processors — will be required to collect, verify, and submit user data directly to HMRC.
This new mandate forms part of the OECD’s Crypto-Asset Reporting Framework (CARF), introduced to combat global tax evasion. For UK investors, this means the era of anonymous crypto gains is officially ending. Whether someone trades NFTs on OpenSea, farms yield in DeFi protocols, or receives airdrops, HMRC wants full transparency.
2. Why Is HMRC Introducing These Rules?
2.1 HMRC’s Philosophy Is Simple: Tax the Digital Economy Like the Physical One
Crypto investment has moved from niche to mainstream. HMRC estimates that over 10% of UK adults now own crypto assets, with billions stored across wallets and exchanges. Yet, tax compliance remains alarmingly low.
Common issues include:
-
Misreporting or ignoring gains from NFT sales
-
No records of DeFi staking or liquidity pool rewards
-
Not declaring airdrops or token incentives
To close this gap, HMRC is implementing real-time surveillance — using compulsory data reports from service providers.
3. Overview of the 2026 Mandatory Reporting Rules
From April 2026, every crypto platform servicing UK residents (even if based abroad) must send HMRC the following data annually:
| Type of Information | What HMRC Requires |
|---|---|
| Personal data | Full name, address, date of birth, national insurance number |
| Wallet & transaction logs | Public wallet addresses, transaction history, asset types |
| Value & currency | GBP-equivalent value of assets at transaction time |
| NFT details | Token ID, project name, sale or purchase value |
| DeFi interactions | Staking amounts, liquidity pool data, lending/borrowing activities |
| Airdrops & rewards | Token type, date received, value at time of receipt |
This information will be matched with annual Self Assessment tax returns. If discrepancies appear, an automated inquiry may be triggered.
4. Line-by-Line Breakdown of the New HMRC Rules
Rule 1: “Crypto-Asset Service Providers Must Identify Users”
Platforms are responsible for verifying user identities using KYC (Know Your Customer) standards. Anonymous accounts will no longer be tolerated for taxable activities.
Rule 2: “Collect and Report Transaction Data Annually”
Every crypto transaction must be categorised and reported, including purchases, disposals, swaps, and gas fees.
Rule 3: “Provide Valuation of Each Transaction in GBP”
HMRC requires all data in British pounds, based on prices at the exact time of transaction.
Rule 4: “Disclose NFT Sales and Transfers”
NFT marketplaces must provide the smart contract address, token ID, and sale proceeds of every NFT transfer involving a UK user.
Rule 5: “Include DeFi Activities Within the Reporting Framework”
This includes staking, lending, yield farming, and liquidity provision — even if there are no direct cash-outs.
Rule 6: “Airdrops Must Be Treated as Income When Received in Exchange for Activity”
If tokens are received for participating in an activity (like sharing posts, holding tokens, or completing tasks), they are considered taxable income.
Rule 7: “Report Cross-Border Transfers to and from Private Wallets”
If crypto moves between an exchange and a self-custody wallet, this must still be reported.
5. NFTs: How They’re Taxed Under 2026 Rules
NFTs are categorised as digital assets subject to Capital Gains Tax (CGT).
| Scenario | Tax Treatment |
|---|---|
| Buying an NFT | No immediate tax |
| Selling for profit | Capital Gains Tax applies |
| Selling at a loss | Allowable loss to offset gains |
| Minting NFTs | Taxed if considered a business activity |
| Trading NFTs repeatedly | May trigger Income Tax instead of CGT |
NFT Creators vs NFT Traders
-
Creators: Profits from primary sales are income from trade (subject to Income Tax + National Insurance).
-
Traders/Collectors: Profit from resale is subject to CGT.
For 2026, HMRC will receive token IDs, wallet addresses, sale prices, and timestamps directly from major marketplaces.
6. DeFi: Staking, Yield Farming, and Liquidity Pools
6.1 Staking
-
Rewards from staking are treated as income at the point they are received.
-
Later disposal (selling or swapping) is subject to CGT.
6.2 Yield Farming and Liquidity Pools
| Activity | Income Tax? | CGT? |
|---|---|---|
| Earning tokens as a reward | Yes, at receipt | |
| Removing liquidity (and receiving more tokens back) | CGT on difference | |
| Lending tokens on DeFi platforms | Income Tax on interest earned |
6.3 HMRC’s 2026 Rule Impact
Earlier, many investors believed DeFi was untraceable. Under CARF, DeFi platforms providing user interfaces will be obliged to report wallet-based returns to HMRC.
7. Airdrops: Free Tokens, But Not Free from Tax
Airdrops fall into two categories:
| Type of Airdrop | Tax Impact |
|---|---|
| Given randomly with no effort | No Income Tax, but CGT applies upon disposal |
| Earned via tasks or promotions | Treated as Income Tax at point of receipt |
From 2026, platforms must report the token value at the time of the airdrop, allowing HMRC to trace undeclared earnings.
8. What Data Will Be Shared with HMRC?
Under the mandatory reporting legislation, platforms must collect:
-
Customer identity details (ID, address, National Insurance number)
-
Transaction history in fiat currency
-
Wallet addresses and smart contract interactions
-
Records for up to 10 years
This data may be shared with foreign tax authorities under international agreements.
9. Penalties for Non-Compliance
For Investors
-
Failure to report crypto gains could lead to:
-
Up to 200% of unpaid tax in penalties
-
Interest on overdue taxes
-
Possible criminal investigation for deliberate evasion
-
For Platforms
-
Heavy fines for failure to submit data
-
Possible UK market exclusion
10. How Should UK Investors Prepare Now?
Step 1: Start Recording Every Transaction
Investors should log:
-
Purchase and sale values
-
Dates of transactions
-
Fees (gas fees included)
-
Exchange or wallet used
Step 2: Clean Up Wallet History
Delete unused wallets and consolidate assets where possible.
Step 3: Seek Professional Guidance
Tax professionals can:
-
Determine whether an investor falls under CGT or Income Tax
-
Assist with Self Assessment
-
Provide advice on inheritance and trust planning for crypto
It is here that some investors consult My Tax Accountant to ensure they are fully compliant before the 2026 enforcement begins.
11. Frequently Asked Questions
❓ Will HMRC know about private wallets?

12. Conclusion
The 2026 crypto reporting rules mark a new chapter in financial transparency. NFTs, DeFi platforms, and airdrops are no longer grey areas in tax law — they are being placed firmly within HMRC’s jurisdiction.
By preparing early, keeping accurate records, and seeking professional advice, UK investors can stay ahead of compliance demands. The message from HMRC is clear: digital assets may be decentralised, but taxation is not.
