Crypto tax, handled properly.

Whether you hold a handful of Bitcoin on an exchange or you're juggling a hundred thousand on-chain transactions across chains, wallets and protocols — we build the report HMRC actually wants to see.

Capital Gains Tax Reports

Full HMRC share-pooling (Section 104) reports with same-day and 30-day rule matching, GBP cost basis, and SA108-ready schedules.

  • Section 104 pool calculations
  • Same-day & bed-and-breakfast rules
  • SA108 capital gains pages

Self Assessment Filing

Full UK Self Assessment submission including SA100, SA108 capital gains (with the dedicated Cryptoassets section) and SA103 where crypto activity constitutes a trade.

  • Daily GBP fair market value
  • Miscellaneous income vs trade test
  • Validator & MEV rewards

HMRC Investigations

Received a nudge letter or opened enquiry? We respond, reconstruct records from on-chain data, and negotiate voluntary disclosures under HMRC's Digital Disclosure Service.

  • Nudge letter response
  • Voluntary disclosures (DDS)

  • Private key succession planning

How HMRC taxes your crypto.

HMRC's position is set out in the Cryptoasset Manual. Crypto is not currency — it is property. That single classification cascades into every rule below, and mis-applying any one of them is how investors accidentally under-report (or over-pay) by thousands of pounds.

01Classification

Crypto is property, not currency

HMRC treats Bitcoin, Ethereum, stablecoins, altcoins, NFTs and most DeFi positions as chargeable assets — the same tax framework as shares. Every disposal is a potential capital event measured in pounds sterling.

02Disposal

What counts as a disposal

Selling crypto for GBP, swapping one crypto for another, spending crypto on goods or services, and gifting crypto (except to a spouse or civil partner) are all disposals. Merely holding, moving between your own wallets, or depositing to a custodian you control is not a disposal.

03Matching

Share-pooling rules apply

HMRC requires three matching rules in strict order: same-day rule, then the 30-day bed-and-breakfasting rule, then the Section 104 pooled average cost. FIFO, LIFO and HIFO are not permitted for UK individuals — the output you get from a US-centric tax tool will almost certainly be wrong by default.

04Allowance

£3,000 annual CGT exemption

For the 2025/26 tax year, the Annual Exempt Amount is £3,000 — down from £6,000 in 2023/24 and £12,300 previously. This allowance covers all your capital gains combined (crypto, shares, property), not just crypto. Gains above this threshold are taxable at 18% or 24%.

05Income

Some crypto is income, not capital

Staking rewards, mining income, airdrops received in exchange for doing something, referral bonuses and being paid in crypto are taxed as income at 0–45%, valued in GBP at the moment of receipt. That GBP value then becomes your cost basis for a future CGT calculation on disposal.

06Disclosure

The £50,000 disposal proceeds rule

If your total disposal proceeds across all chargeable assets exceed £50,000 in the tax year — even if your net gain is below the annual exemption — you must file a Self Assessment and report the disposals. This catches a surprising number of active traders off-guard.

07CARF

CARF reporting from January 2026

Under the Crypto-Asset Reporting Framework, all UK-operating exchanges must collect and share detailed customer transaction data with HMRC from 1 January 2026. The era of undetectable crypto activity is over — compliance is no longer optional.

What triggers tax, exactly.

A quick map of which actions are capital events, which are income, and which are non-events. Most crypto tax mistakes come from misclassifying something in this grid.

01
Capital Gains

Selling for GBP

Disposal at the GBP proceeds received, minus pooled cost basis and allowable fees.

02
Capital Gains

Crypto-to-crypto swap

Treated as two separate events — disposal of Token A, acquisition of Token B, at market value.

03
Capital Gains

Spending crypto

Buying coffee or a car with BTC is a disposal at GBP fair market value on the transaction date.

04
Capital Gains

Gifting (non-spouse)

Gift to anyone other than a spouse or civil partner is a disposal at market value.

05
Income Tax

Staking rewards

Taxed as miscellaneous income at GBP value on receipt. Becomes cost basis for future disposal.

06
Income Tax

Mining rewards

Income at GBP value on receipt; may be miscellaneous income or trade depending on scale and organisation.

07
Income Tax

Airdrops (for something)

If received in exchange for a service or social action — taxed as income. If truly unsolicited — CGT only on disposal.

08
Income Tax

Paid in crypto (salary)

Subject to PAYE income tax and National Insurance at GBP value on pay date.

09
Not Taxable

Buying with GBP

Buying crypto with pounds sterling is not a taxable event — it establishes your cost basis.

The rates you'll actually pay.

The 30 October 2024 Autumn Budget aligned crypto CGT rates with the rates previously used for residential property. Here's where you stand for the current tax year.

Band / Type Income Level Rate Notes
CGT — Basic rate Total income ≤ £50,270 18% On gains above £3,000 exemption
CGT — Higher/Additional Total income > £50,270 24% On gains above £3,000 exemption
Income — Personal Allowance Up to £12,570 0% Tapered above £100,000
Income — Basic rate £12,571 – £50,270 20% Applies to staking, mining, airdrops
Income — Higher rate £50,271 – £125,140 40% Includes crypto earned as salary
Income — Additional rate Over £125,140 45% Personal allowance fully withdrawn
Trading Allowance Miscellaneous income £1,000 Tax-free annual threshold
Annual CGT Exemption All chargeable assets £3,000 Combined across crypto, shares, property

Scottish taxpayers are subject to Scottish Income Tax rates and bands, which differ from the rest of the UK. Capital Gains Tax rates are the same across the UK.

Built for every kind of holder.

Common Misconception

Crypto tax is not filed through MTD.

We get asked this constantly, so it's worth setting out plainly. If you already use Making Tax Digital for your business or rental income, you may assume your crypto goes through the same pipeline. It doesn't — and the distinction changes what tools and deadlines apply to you.

Does not apply

Making Tax Digital (MTD)

MTD for Income Tax Self Assessment · quarterly digital submissions
  • Applies only to sole traders and landlords with qualifying business or property income above the HMRC threshold
  • Requires quarterly updates of income and expenses through MTD-compatible software
  • Uses a separate set of HMRC developer APIs scoped to trade and property income
  • Does not include a cryptoasset endpoint, schema or submission category
  • HMRC has published no plans to bring personal crypto investment activity inside MTD
Applies to crypto

Annual Self Assessment

SA100 + SA108 Capital Gains Summary · filed once per tax year
  • All personal crypto capital gains are reported in the annual Self Assessment return
  • From 2024/25, the SA108 includes a dedicated Cryptoassets section (boxes 13.1–13.8)
  • Filed online via the Government Gateway or through agent-accredited SA software
  • HMRC also offers a Real Time Capital Gains Tax service for reporting disposals mid-year
  • Crypto treated as a trade (rare — under the badges of trade) may sit inside MTD via SA103
What this means for you. If we file on your behalf, the submission goes through HMRC's Self Assessment channel — either the agent online services portal or accredited Self Assessment software — not an MTD endpoint. The output is the same as any other annual Self Assessment: a tax return receipt, a unique submission reference, and the liability added to your HMRC account. If someone markets "MTD-compliant crypto filing" to you, treat that as a red flag — no such route exists.
Separately — CARF reporting from January 2026. This is often confused with MTD because both involve automated HMRC data flows. CARF is reporting by exchanges to HMRC, not a filing channel for you. Your obligation remains annual Self Assessment; CARF simply gives HMRC a second source of truth to reconcile your return against.

What investors say about us.

After three years of DeFi farming I thought my position was unreportable. They reconstructed everything from on-chain data and delivered a schedule HMRC accepted without a single query.

I was using a popular crypto tax app that applied FIFO by default. Crypto Tax UK spotted it, redid my pool under Section 104, and saved me over £4,000 in overstated gains.

Questions we always get asked.

Yes. HMRC treats most cryptoassets as chargeable property. Capital Gains Tax applies when you dispose of crypto (sell, swap, spend, or gift outside a spouse). Income Tax applies to mining, staking rewards, airdrops received for services, and being paid in crypto. The annual CGT allowance for 2025/26 is £3,000 — gains above this are taxed at 18% (basic rate) or 24% (higher/additional rate).

For the 2025/26 tax year, crypto CGT is 18% for basic-rate taxpayers and 24% for higher and additional-rate taxpayers. The old 10%/20% rates applied only to disposals made on or before 29 October 2024. The rate applies to total net gains above the £3,000 annual exempt amount, and the exemption covers all chargeable assets combined.

Yes. HMRC treats crypto-to-crypto swaps as a disposal of the first asset at its GBP market value on the date of the swap, and an acquisition of the second at the same value. A capital gain or loss crystallises even though no fiat has changed hands — which is why investors often owe tax on transactions where they never "cashed out".

HMRC applies share-matching rules in a strict order. First, the same-day rule matches any disposal against acquisitions of the same token on the same day. Second, the 30-day bed-and-breakfasting rule matches against acquisitions in the following 30 days. Finally, any remaining disposal is matched against the Section 104 pool — a running weighted average of your historical holdings. FIFO is not permitted for UK individuals, which is why many crypto tax tools produce incorrect UK output by default.

Yes. HMRC has active data-sharing agreements with major UK and international exchanges including Binance, Coinbase, Kraken and others, and uses this data to issue "nudge letters" to taxpayers it suspects have underreported. From 1 January 2026, under the Crypto-Asset Reporting Framework (CARF), all UK-operating exchanges must collect and share detailed customer transaction data with HMRC — with fines of up to £300 per user for non-compliance.

You still have to file. HMRC requires a Self Assessment whenever total disposal proceeds across all chargeable assets exceed £50,000 in a tax year — regardless of whether your net gain is above or below the £3,000 annual exemption. This is a common trap for active traders whose gross trading volume triggers a filing obligation even on a year with low net profit.

Both — at different times. Staking rewards are taxed as miscellaneous income at the GBP value of the tokens on the date they are received. That GBP value then becomes the cost basis for the tokens, so when you later dispose of them, you also have a capital gain or loss calculation based on the difference between sale proceeds and the recorded income value. Liquid staking (stETH, rETH) has additional nuance we handle case-by-case.

Yes. Capital losses from crypto disposals can offset capital gains from crypto, shares, property and other chargeable assets in the same tax year, or be carried forward indefinitely to offset future gains. You must claim losses formally via Self Assessment within four years of the end of the tax year in which they arose — many investors miss this and permanently lose the relief.

Lost private keys do not automatically generate a capital loss, because HMRC considers you still the beneficial owner. You may, however, make a Negligible Value Claim if you can demonstrate the crypto is genuinely worthless or irrecoverable. Stolen crypto is generally not deductible. We assess each case against HMRC's specific tests.

No. Making Tax Digital for Income Tax Self Assessment is a separate regime scoped to sole traders and landlords with qualifying business or property income above HMRC's threshold. Personal crypto investment activity is reported through annual Self Assessment — SA100 and SA108 — using HMRC's online Self Assessment service or accredited SA software, not an MTD endpoint. HMRC has published no plans to bring personal crypto gains inside MTD. If you come across a service marketing "MTD-compliant crypto filing", treat it as a warning sign — no such submission route exists. The exception is where crypto activity genuinely constitutes a trade under the badges of trade (rare for individual investors), in which case trading profits may sit inside MTD via SA103 once you pass the income threshold.

CARF is a reporting obligation placed on cryptoasset service providers — exchanges, custodial wallet providers and some DeFi platforms operating in the UK. From 1 January 2026 they must collect identifying information and transaction data for UK users and submit it to HMRC annually, with the first report covering calendar year 2026 due by 31 May 2027. This does not change your filing obligation: you still submit an annual Self Assessment declaring gains and income in the normal way. CARF simply gives HMRC a second source of truth to reconcile your Self Assessment against, which is why accurate pooling and disclosure matter more than ever from the 2025/26 tax year onwards.
