Worth knowing
Rules that come up in this work
Switching accountants
You can switch accountant at any point in the year. The new firm requests clearance and your records from the old one, which cannot withhold your own documents though it may hold its own working papers until its fees are settled. Agent authorisations with HMRC and Companies House are transferred, and the next deadline is picked up without a gap.
Closing a company
Voluntary strike-off is available only to solvent companies. One that owes money it cannot pay needs a creditors' voluntary liquidation through a licensed insolvency practitioner, and directors who dissolve an insolvent company face personal consequences. For a solvent company the process takes three to four months from filing the DS01, with notice to creditors and shareholders within seven days.
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
Not every small income needs a tax return. The trading allowance exempts the first £1,000 of self-employment or casual income and the property allowance does the same for rental income, each measured on gross receipts. They cannot be combined with rent-a-room relief on the same income, and claiming the allowance means giving up the expense deduction for that source.
Employer National Insurance
Since April 2025 employer National Insurance has been 15% on earnings above a £5,000 secondary threshold, a substantial increase for small employers. The Employment Allowance rose to £10,500 at the same time to soften it for the smallest businesses. Directors deciding their own salary weigh this cost against the Corporation Tax deduction a salary provides.
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
Record keeping is a legal obligation with a penalty of up to £3,000 for failure, but its real value is in making every other filing cheaper and more defensible. Keep invoices, receipts, bank statements, mileage logs and any HMRC correspondence, digitally if you like, for five years after the relevant filing deadline for individuals and six years for companies and VAT.
Questions
Crypto Tax questions from Harefield
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.
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.
How is the fee set?
By transaction count. Up to 500 transactions across all exchanges and wallets is £199 for the report alone or £279 with your Self Assessment filed. Over 500 is £399. A response to an HMRC nudge letter, including the report and the reply, is £249. We confirm the band from your exports before starting.
I received an HMRC letter about crypto. What should I do?
Do not ignore it and do not reply without the figures. HMRC's nudge letters are sent where exchange data suggests undeclared activity. We prepare the full report, work out what should have been declared, and draft the response, including a voluntary disclosure where tax is owed, which reduces penalties substantially compared with being caught.
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 Harefield 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.
