Worth knowing
Rules that come up in this work
Dormant companies
Dormancy is a status that is easy to lose. The strict rule is no accounting transactions other than share capital and Companies House fees, which means no bank account activity at all in practice. Fees should be paid personally by the director. A company that traded and has stopped becomes dormant only after its final trading accounts and tax return are filed and HMRC is told.
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
The cost of an employee is more than the salary. Employer National Insurance at 15% above £5,000 a year, the 3% minimum pension contribution, holiday pay, equipment and management time all come on top. The Employment Allowance of £10,500 reduces the National Insurance for most employers with more than one person on the payroll.
Workplace pensions and auto-enrolment
Auto-enrolment duties begin the day you take on your first employee, not when the Pensions Regulator writes to you. Eligible staff must be enrolled, contributions paid every pay period and re-enrolment carried out every three years. Director-only companies without employment contracts are usually exempt. Fines for non-compliance are fixed and escalating.
Record keeping
Good records are the difference between a quick enquiry and a long one. For the self-employed, five years after the filing deadline; for companies, six years from the year end; for VAT, six years. Photographs of receipts, PDF statements and software exports all count. The requirement is to keep records, not paper, and a well-organised cloud folder satisfies it.
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.
Questions
Crypto Tax questions from Brentford Lock
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 need to register for Self Assessment just for crypto?
If your total disposals exceed £50,000 in the year, or your gains exceed the £3,000 allowance, or you have taxable crypto income, yes. Register by 5 October after the tax year. Since 2024/25 the return has a dedicated section for cryptoassets. We handle registration where you are not already filing.
Are NFTs treated the same as coins?
Each NFT is a separate asset, so pooling does not apply; the gain is proceeds less the cost of that specific token including gas fees. Creating and selling NFTs regularly may be trading income rather than capital gains. Royalties received are income. We classify each case from the facts.
My exchange collapsed and I lost everything. Can I claim the loss?
Possibly. If the tokens still exist but you cannot access them, a negligible value claim may be available once the asset is effectively worthless. If the exchange is in administration you may need to wait for the outcome. We assess each case against HMRC's guidance and make the claim where it is supportable.
What do you need from me?
Full transaction exports from every exchange you have used, including closed accounts, and wallet addresses for on-chain activity. Partial history produces wrong pool costs, so completeness matters more than tidiness. We tell you exactly how to export from each major platform.

The next four dates that apply to crypto tax are shown at the top of this page, calculated from today. For Brentford Lock 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.
