We support a wide range of UK individuals who need accurate, compliant and professionally prepared crypto self assessment tax returns.
Many investors assume they only pay tax when converting to GBP. In reality, token swaps, disposals and certain transfers can all trigger Capital Gains Tax under rules set by HMRC.
Frequent trading creates complex pooling calculations and matching rules. Incorrect reporting can easily lead to under or overpayment of tax.
Decentralised finance activity introduces additional tax considerations beyond simple buy and sell transactions.
If this is your first time declaring crypto on your Self Assessment, it is important to understand what needs to be reported and why.
Many company directors and higher earners invest personally in cryptocurrency alongside employment or business income.
If you have not declared crypto gains in earlier tax years, acting early reduces risk.
Real client feedback from investors who trusted us to file their crypto self assessment tax returns accurately and on time
GoForma, particularly Jordan Macey from GoForma, have been fantastic from the moment I have been with them. Consistently taking the time to provide the highest standard of advice. They have even continued with their fantastic service when due to financial difficulties I had to pause payment.
Having dealt with GoForma personally I was extremely happy with the pricing and ultimately speed of the services. Definitely will be using them for the next tax year.
I wholeheartedly recommend GoForma. From initial set up of my company, to helping me with numerous tax related queries, and efficiently and promptly assisting me to meet all my tax reporting deadlines, to finalising the closedown of my Ltd company when I chose to retire, they have been fantastic.
The whole goforma experience has been amazing. Jawad fitchett has helped me above and beyond and I would definitely recommend him and the company.

Everything you need to know crypto tax return and our service. Can't find the answer?

Yes, you must declare cryptocurrency on your Self Assessment tax return if you disposed of crypto during the tax year or received taxable crypto income.
Yes. Swapping one cryptocurrency for another is treated as a disposal for Capital Gains Tax purposes in the UK. Even if you did not convert to pounds, HMRC considers the transaction taxable. The gain is calculated based on the market value of the crypto at the time of the swap.
In most cases, staking rewards are taxed as income at their value in pounds when received. You may then also pay Capital Gains Tax if you later sell those tokens at a higher price.
If you made a loss when disposing of cryptocurrency, you may be able to report that loss on your crypto self assessment tax return. Capital losses can reduce your Capital Gains Tax bill or be carried forward to future tax years. Losses must still be reported correctly to be valid.
If you did not declare crypto gains in earlier years, you should take action as soon as possible. You can amend recent returns or make a voluntary disclosure to HMRC.
HMRC has data sharing agreements with UK and international crypto exchanges. Exchanges may provide transaction data when requested. HMRC also has powers to request information directly from financial institutions. Assuming crypto is invisible to HMRC is a serious mistake.
Our fixed fee of £275 covers Capital Gains Tax calculations based on up to 25,000 cryptocurrency transactions for one tax year. If your portfolio exceeds this volume or involves complex structures, we will provide a clear bespoke quote before starting work.
Yes. If you already file a Self Assessment tax return and only need help with the crypto reporting section, we can prepare the Capital Gains Tax and Income Tax calculations and complete the relevant disclosures accurately.
You should keep records of transaction dates, values in pounds at the time of each transaction, exchange statements, wallet records and details of fees paid. Good record keeping supports accurate crypto self assessment tax returns and protects you in case of an HMRC enquiry.
Crypto taxation involves pooling rules, matching rules and income classification that differ from traditional investments. A specialist crypto tax accountant understands how HMRC applies these rules to digital assets, which reduces the risk of errors or under reporting.
At GoForma, we follow a clear and structured process so your crypto self assessment tax return is prepared accurately, filed correctly and submitted to HMRC.
We begin with a short consultation to understand your crypto activity for the tax year. We discuss exchanges used, wallets held, trading frequency, staking, mining or other income sources.
You securely upload your transaction reports from exchanges, wallets or crypto tax software. If you have up to 25,000 cryptocurrency transactions, this service covers full capital gains calculations within our fixed fee.
We review your full transaction history and calculate Capital Gains Tax on disposals, Income Tax on qualifying crypto income, and Allowable losses and annual exemptions.
Once calculations are complete, we prepare your Self Assessment tax return with all relevant crypto disclosures included. We clearly separate capital gains and income figures and integrate them with your wider tax position.
After your approval, we submit your crypto self assessment tax return electronically to HMRC. You receive confirmation of filing and a copy of your completed return for your records.
We provide a clear breakdown of Total taxable gains, Income subject to tax, Tax payable, and Payment deadlines. If you need support with voluntary disclosure for earlier years or assistance in the event of an HMRC enquiry, we can discuss this separately.

HMRC treats cryptoassets as property, not currency. This means different tax rules apply depending on what you did with your cryptocurrency during the tax year.
Capital Gains Tax applies when you dispose of crypto. A disposal does not only mean selling for cash.
You may need to pay Capital Gains Tax if you:
HMRC applies share pooling rules when calculating crypto gains. Instead of tracking each coin separately, your tokens are grouped into a single pool for that asset. The average cost is used to calculate gains when you dispose of part of your holding.
The 30 day rule also applies. If you sell crypto and buy the same asset again within 30 days, special matching rules affect how your gain or loss is calculated. Many investors overlook this rule, which can lead to incorrect reporting.
In some cases, crypto is taxed as income rather than a capital gain.
Income Tax may apply if you receive:
These amounts are usually taxed based on their value in GBP at the time you receive them. If you later sell those tokens, you may also face Capital Gains Tax on any increase in value.
If crypto income is reported as a capital gain, or vice versa, you could under report tax or pay more than necessary. Professional review reduces this risk and keeps your return aligned with HMRC guidance.
This is a fixed fee one time filing service for a specific tax year. It does not include ongoing bookkeeping, trading advice or continuous tax planning. The focus is accurate calculation and compliant submission of your crypto self assessment tax return.
