Worth knowing
Rules that come up in this work
Record keeping
HMRC requires records of all income and expenses, bank statements, invoices and receipts to be kept for at least five years after the 31 January filing deadline of the tax year they relate to, and companies must keep records for six years from the end of the accounting period. Digital copies are acceptable. Under Making Tax Digital the records must be kept in compatible software.
Allowable expenses
An expense is allowable against trading profit if it is incurred wholly and exclusively for the business. Materials, business travel other than ordinary commuting, a proportion of home running costs, software, insurance, professional fees, bank charges and protective clothing qualify. Client entertainment, ordinary clothing, fines and the private share of mixed-use costs do not.
Crypto records and reporting
Most crypto holders have taxable events they do not recognise, because every swap is a disposal even when no pounds change hands. The computation requires the complete transaction history from every exchange and wallet, pooled by asset with HMRC's matching rules applied. Exchange-generated tax reports are frequently wrong because they cannot see transfers between a user's own wallets.
The 60-day property CGT return
Since April 2020 a gain on UK residential property must be reported and the tax paid within 60 days of completion through HMRC's dedicated service, separately from the annual return. Non-residents must report all UK land disposals in the same window whether or not tax is due. Getting the computation right first time matters because the figure is then carried into the Self Assessment.
Dormant companies
A dormant company is one with no significant accounting transactions in the year, where the only permitted entries are the payment for shares on incorporation, Companies House fees and penalties. It still files a confirmation statement and simplified dormant accounts every year. A bank charge or an accountant's fee paid from the company ends dormancy and requires full accounts.
The trading and property allowances
The first £1,000 of trading income and, separately, the first £1,000 of property income each year is tax free under the trading and property allowances. Below those figures no return is needed for that income. Above them you can deduct the £1,000 allowance instead of actual expenses if that is better, which suits side businesses and single-room lets with few costs.
Employer National Insurance
Employers pay National Insurance at 15% on each employee's earnings above the £5,000 secondary threshold, following the April 2025 changes. The Employment Allowance offsets up to £10,500 of this for eligible employers, which for a small team often removes the liability entirely, but companies where the director is the only employee do not qualify.
Questions
Crypto Tax questions from Harmondsworth
How far back do I need to go?
The pool cost of what you hold today depends on every purchase you have ever made, so the computation must start from your first transaction even if you only need to report recent years. If earlier years were under-reported, we quantify the position and advise on disclosure, which HMRC treats far more leniently than discovery.
What if I am a trader rather than an investor?
HMRC rarely accepts that an individual is trading in crypto; the bar is very high and the badges of trade must be met. If you are trading, profits are income and losses are trading losses. For almost everyone the capital gains treatment applies, and we tell you plainly which side of the line you are on.
Do I pay tax if I never cashed out to pounds?
Usually yes. Swapping one cryptoasset for another, spending crypto on goods or services, and gifting it to anyone other than a spouse are all disposals for Capital Gains Tax, valued in sterling at the time. Only moving coins between your own wallets is not a disposal. Most people's taxable events are swaps, not sales for cash.
How are gains calculated with so many purchases at different prices?
HMRC requires pooling: all units of the same token form one section 104 pool with an average cost, except that disposals are first matched against purchases on the same day and then against purchases within the following 30 days. We apply these rules across your entire history, which is impossible to do accurately by hand at any volume.
What are the Capital Gains Tax rates and allowance?
The annual exempt amount is £3,000 for 2026/27. Gains above it are taxed at 18% within your basic rate band and 24% above it. Losses in the year are set against gains automatically, and unused losses can be carried forward indefinitely if claimed on a return within four years.
Is staking income a capital gain?
No. Rewards from staking, lending, liquidity provision and most DeFi protocols are income when received, taxed at your income tax rate on the sterling value that day, and reported as miscellaneous income unless your activity amounts to a trade. The tokens then enter your pool at that value for a later capital gain or loss.
Which deadlines matter most for crypto tax?
The next four dates that apply to crypto tax are shown at the top of this page, calculated from today. For Harmondsworth clients we diarise every one of them from the day you join and send reminders before each, so the work is done in good time rather than in the last week before a penalty.
