HMRC

UK Crypto Tax Basics

The essentials every UK investor asks first.

Do I have to pay tax on cryptocurrency in the UK?

Yes. HMRC treats cryptoassets as taxable property. Depending on the transaction you may owe Capital Gains Tax, Income Tax, or both. Simply buying and holding crypto is not taxable, but selling, swapping, spending, gifting (other than to a spouse or civil partner), or earning crypto through staking, mining or airdrops can all create a tax liability.

I haven't cashed out to GBP. Do I still owe tax if I only swapped one crypto for another?

Yes — this is the most common misconception we see. HMRC treats crypto-to-crypto swaps, including swaps into stablecoins like USDT or USDC, as a disposal. You must calculate the sterling value of the asset at the moment of the trade, and any gain since you acquired it is subject to Capital Gains Tax, even though you never touched fiat.

What crypto transactions are taxable in the UK?

You have a taxable event when you sell crypto for GBP or another fiat currency, exchange one cryptoasset for another, spend crypto on goods or services, or gift crypto to anyone other than your spouse or civil partner. Receiving crypto from staking, mining, employment, lending or certain airdrops is usually taxed as income. Buying and holding is generally not taxable.

How much can I make in crypto tax-free in the UK?

The Capital Gains Tax Annual Exempt Amount is £3,000 per tax year, so you only pay CGT on net gains above that (the allowance covers all your capital assets, not just crypto). Crypto received as income — staking, mining, employment — falls under Income Tax, where your £12,570 personal allowance applies, plus the £1,000 trading/miscellaneous income allowance in some cases.

What are the current UK tax rates on crypto?

Gains above the £3,000 allowance are taxed at 18% for basic-rate taxpayers and 24% for higher and additional-rate taxpayers. Crypto taxed as income is charged at your normal Income Tax rates of 20%, 40% or 45% depending on your band, and National Insurance can also apply if the activity amounts to a trade or employment income.

Do I pay Income Tax or Capital Gains Tax on my crypto?

It depends on how you received it. Capital Gains Tax applies when you dispose of crypto held as an investment. Income Tax applies to crypto received as earnings — staking rewards, mining, airdrops received for a service, DeFi yield, or salary paid in crypto. Many investors owe both: Income Tax when rewards are received, then CGT on any further gain when those tokens are later sold.

How does HMRC know about my crypto?

HMRC's visibility has never been higher. Under the Crypto-Asset Reporting Framework (CARF), in force from January 2026, exchanges and custodians must automatically report customer transactions, identities and tax reference numbers to tax authorities. HMRC also runs compliance requests against UK and overseas exchanges, receives data through international agreements, uses blockchain analytics to trace wallets, and sends 'nudge letters' to suspected non-reporters.

Do I need to report my crypto to HMRC?

Yes, if your total gains exceed the £3,000 annual allowance, your total disposal proceeds exceed £50,000 in a tax year, you have crypto income to declare, or you already file a Self Assessment return. Since the 2024/25 return, cryptoassets must be identified separately on the SA108 capital gains pages. You can report via Self Assessment or HMRC's real-time CGT service.

What records do I need to keep for my crypto taxes?

HMRC expects complete records for every transaction: the date and type of transaction, amounts in crypto and their GBP value at the time, fees paid, wallet addresses and transaction IDs, exchange statements, and your pooled cost-basis calculations. Keep records for at least five years after the 31 January filing deadline — good records are your best defence if HMRC opens an enquiry.

What are the Self Assessment deadlines for crypto investors?

The UK tax year runs 6 April to 5 April. You must register for Self Assessment by 5 October following the tax year, file a paper return by 31 October, or file online and pay by 31 January. Miss the deadline and penalties start at £100 and escalate, with interest on late tax — so if you have crypto gains for the first time, register early.

HMRC Rules, DeFi & Calculations

Share pooling, DeFi, NFTs, losses and company structures.

How does HMRC calculate my gain if I bought the same coin at different prices?

You cannot pick and choose which coins you sold. HMRC applies share matching rules in strict order: first the Same-Day Rule (disposals matched with purchases the same day), then the 30-Day 'Bed and Breakfasting' Rule (purchases within 30 days after the disposal), and finally the Section 104 pool, which uses the average acquisition cost of your remaining holding of that token.

How do the Same-Day and 30-Day rules affect high-volume traders?

These rules exist to stop investors selling at a loss and instantly buying back to harvest tax losses. For frequent traders they can dramatically change your taxable gain, because disposals are matched to recent purchases at their actual cost rather than your long-term average. High-volume trading across multiple venues makes manual calculation practically impossible — specialist software plus professional review is the safe route.

How are staking, lending, liquidity pools and yield farming taxed in the UK?

Staking and lending rewards are generally taxed as income at their GBP market value when received, with CGT due on any further gain when you dispose of them. Entering a liquidity pool and receiving LP tokens is treated by default as a disposal of your original tokens, though the government has proposed 'no gain, no loss' rules for DeFi lending and staking. DeFi remains the most complex area of UK crypto tax — professional review is strongly recommended.

How are NFTs, wrapped tokens and cross-chain bridges taxed?

Tax follows the substance of the transaction, not the technology. NFT sales and token swaps are normally CGT disposals. Wrapping (e.g. BTC to wBTC) technically exchanges one asset for a different token, so HMRC generally treats it as a taxable swap. Bridging may or may not be taxable depending on whether beneficial ownership of the asset changes — each protocol needs to be reviewed on its own terms.

When does crypto trading become subject to Income Tax instead of CGT?

Almost all private investors fall under CGT, but if your activity amounts to a financial trade, profits are taxed as income with National Insurance on top. HMRC applies the 'Badges of Trade' test: frequency and volume of transactions, short holding periods, use of leverage, and how organised and business-like your operation is. The bar is high, but professional day traders can cross it — get advice before assuming either way.

Can I claim a loss if my exchange collapsed or I was scammed?

Sometimes. If you sent crypto to a fraudster in a scam or rug pull, HMRC generally does not treat that as a disposal, so no capital loss arises. But if your tokens have become genuinely worthless, or an exchange has failed and your assets are permanently unrecoverable, you may be able to make a Negligible Value Claim to crystallise the loss and offset it against other gains. The facts matter — we review these case by case.

Can I use crypto losses to reduce my tax bill?

Yes. Realised losses offset gains in the same tax year, and unused losses carry forward indefinitely against future gains — but only if they are reported to HMRC, normally within four years via Self Assessment. Registering losses in bad years is one of the most valuable and most-missed steps we see with new clients.

How do I calculate gains across multiple exchanges and wallets?

HMRC requires pooled calculations across all your holdings, not exchange-by-exchange. That means reconciling every exchange, wallet and chain, identifying transfers between your own wallets (not taxable), applying the share matching rules, and valuing everything in GBP. We combine specialist crypto tax software with accountant-level review to produce one defensible HMRC-ready computation.

Should I hold my crypto through a UK limited company?

It can work for active traders and Web3 businesses — Corporation Tax rates can beat higher-rate CGT/Income Tax and expenses become deductible — but there are traps. Transferring personally held crypto into a company is itself a disposal at market value, which can trigger an immediate CGT bill, and extracting profits later via salary or dividends creates a second layer of tax. This is a modelling exercise, not a rule of thumb: speak to our advisory team first.

Working With a Crypto Accountant

Fees, disclosures, nudge letters and tax planning.

What does a crypto accountant actually do?

A specialist crypto accountant reconciles your full on-chain and exchange history, applies the correct tax treatment to every transaction type — trades, DeFi, NFTs, staking, airdrops — calculates your position under HMRC's pooling rules, files your Self Assessment or company returns, and plans ahead to legally minimise future tax. General accountants rarely have the tooling or the technical crypto knowledge to do this accurately.

How much does a crypto tax accountant cost in the UK?

It depends on transaction volume and complexity. A simple investor return with a few hundred transactions costs far less than a DeFi-heavy portfolio with tens of thousands of events across many chains. We quote a fixed fee up front after a free consultation, and our free Crypto Tax Calculator UK and AI Accountant keep costs down by automating the heavy lifting.

I've never declared my crypto. Can you help me come forward before HMRC finds me?

Yes — and acting first matters. HMRC offers a cryptoasset voluntary disclosure facility, and penalties are significantly lower when you approach HMRC before they approach you. With CARF exchange data flowing to HMRC from 2026, historic non-disclosure is increasingly visible. We handle the disclosure, calculate the historic liabilities, and negotiate the position on your behalf.

I received a nudge letter from HMRC about my crypto. What should I do?

Don't ignore it, and don't respond without checking your numbers first. A nudge letter means HMRC has data suggesting you hold or have disposed of crypto. We review your full history, quantify any undeclared liability, and respond with an accurate disclosure — which is dramatically cheaper than an HMRC enquiry finding errors later.

Can I legally reduce my crypto tax bill?

Yes. Legitimate strategies include using your annual CGT allowance every year, realising and registering losses, transferring assets between spouses or civil partners to use both allowances and lower bands, timing disposals across tax years, claiming every allowable cost, and pension or structure planning where appropriate. Good crypto tax planning is done before you sell, not after.

Do I really need an accountant, or is crypto tax software enough?

Software like Koinly or CoinTracking is excellent at aggregating data, but it guesses at classifications — and DeFi, bridges, wrapped tokens and lost/scammed assets are routinely misclassified. For simple portfolios software may be fine. For anything complex, an accountant validates the output, applies the correct treatment, and signs a return you can defend. We support both: use our free tools first, and bring us in when it stops being simple.

Do you only work with UK clients?

Our core practice is UK/HMRC, but we regularly act for non-doms, expats and internationally mobile clients, and we coordinate with US CPAs and Australian tax agents for cross-border cases. If you have moved country mid-portfolio, residency-based tax planning is one of the most valuable conversations you can have with us.

USA

United States — IRS Crypto Tax

What US taxpayers and UK-based Americans ask us.

How is cryptocurrency taxed in the United States?

The IRS treats crypto as property. Selling, swapping or spending crypto triggers capital gains tax, while staking rewards, mining, airdrops and crypto received as payment are ordinary income at fair market value when received. Every US taxpayer must also answer the digital asset question on the front page of Form 1040.

What's the difference between short-term and long-term crypto gains in the US?

Assets held one year or less are short-term and taxed at ordinary income rates up to 37%. Assets held longer than a year qualify for long-term rates of 0%, 15% or 20% depending on your income. Holding period tracking across wallets is therefore one of the highest-value pieces of US crypto tax planning.

Does the wash sale rule apply to crypto in the US?

As of the 2025 tax year, the wash sale rule applies to securities and does not apply to crypto treated as property — meaning you can sell at a loss and immediately rebuy, harvesting the loss. Congress has repeatedly proposed closing this, so check the current rules before relying on it. Note the contrast with the UK, where the 30-day rule blocks exactly this strategy.

Will the IRS know about my crypto? What is Form 1099-DA?

Yes. From the 2025 tax year, US brokers and exchanges must issue Form 1099-DA reporting your digital asset sale proceeds directly to the IRS. The IRS also requires wallet-by-wallet cost basis tracking from January 2025 and uses blockchain analytics and John Doe summonses against exchanges. Unreported crypto is far more visible than most investors assume.

How do I report crypto on my US tax return?

Capital gains and losses go on Form 8949 and Schedule D; crypto income goes on Schedule 1 or Schedule C (if self-employed, with self-employment tax). You must answer the digital asset question on Form 1040 truthfully — answering falsely is perjury. US filers abroad may also have FBAR/FATCA considerations for certain exchange accounts.

I'm a US citizen living in the UK. Who taxes my crypto?

Potentially both. The US taxes citizens on worldwide income wherever they live, and the UK taxes you as a resident — with the US-UK tax treaty and foreign tax credits preventing most double taxation, but the compliance is genuinely complex (different tax years, different cost-basis rules, different treatment of staking). This is a core cross-border case we handle alongside US CPAs.

Australia

Australia — ATO Crypto Tax

What Australian investors ask about the ATO's rules.

How is crypto taxed in Australia?

The ATO treats crypto as a CGT asset. Selling, swapping, spending or gifting crypto triggers a CGT event, with gains taxed at your marginal income tax rate. Crypto earned from staking, airdrops, mining (non-hobby) or as payment is ordinary income at market value when received. Simply buying and holding is not taxable.

What is the 50% CGT discount for crypto in Australia?

Australian resident individuals who hold a cryptoasset for more than 12 months before disposal can discount the capital gain by 50%. This is the single biggest lever in Australian crypto tax planning — a disposal one day past the 12-month mark can halve the taxable gain compared with a disposal one day before it.

Is there a tax-free threshold or personal use exemption for crypto in Australia?

There is no crypto-specific tax-free allowance — gains are simply added to your income, so the general $18,200 tax-free threshold applies to your total income. The personal use asset exemption can apply to crypto acquired for under $10,000 and used promptly to buy goods or services, but the ATO interprets it very narrowly — it almost never covers crypto held as an investment.

Does the ATO know about my crypto?

Yes. The ATO has run a crypto data-matching program with Australian designated service providers for years, collecting account and transaction data covering millions of taxpayers, and pre-fills warnings into myTax. Australia is also implementing CARF for international exchange-of-information. Assume the ATO can see your exchange activity.

How are staking rewards and airdrops taxed in Australia?

Staking rewards and most airdrops are ordinary income at their AUD market value when you receive them, taxed at your marginal rate. The tokens then have that value as their cost base, and a later disposal triggers a separate CGT event. Initial allocation airdrops with no established value can differ — treatment depends on the facts.

Am I an investor or a trader in the ATO's eyes?

Most individuals are investors: CGT applies and the 50% discount is available. If you operate in a business-like way — high frequency, systems, profit motive as a business — you may be a trader, taxed on trading stock rules with no CGT discount but broader deductions. The classification changes everything, so get advice if you're near the line.

Global

Cross-Border & General

Moving countries, comparing regimes, and the small print.

I moved between the UK, US or Australia mid-year. Which country taxes my crypto?

Residency rules decide, and they differ: the UK uses the Statutory Residence Test with split-year treatment, the US taxes citizens regardless of residence, and Australia has its own residency tests plus a deemed CGT disposal when you cease residency (with an election to defer). Timing disposals around a move can save — or cost — enormous amounts. Cross-border crypto is a specialist area: get advice before you move, not after.

Which country has the lowest crypto taxes — UK, US or Australia?

It depends on your profile. Long-term US holders can pay as little as 0–20% federal; Australia halves gains held over 12 months but taxes the rest at marginal rates up to 45%; the UK caps CGT at 24% but has a tiny £3,000 allowance and no long-hold discount. Relocating purely for crypto tax rarely works as cleanly as social media suggests — exit taxes, residency tests and anti-avoidance rules all bite.
