Worth knowing
Rules that come up in this work
Switching accountants
The main reasons people switch accountant are surprise invoices, missed deadlines and not understanding what they are being told. Switching involves a clearance letter between the firms, a transfer of records and agent authorisations, and a short handover of the current position. It takes about two weeks and should cost nothing extra.
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.
Crypto records and reporting
HMRC treats cryptoassets as property. Swapping one token for another, spending crypto or gifting it are all disposals for Capital Gains Tax, and staking and lending rewards are income. Gains are computed under pooling rules with same-day and 30-day matching. From 2026 HMRC receives data from exchanges worldwide under the Cryptoasset Reporting Framework, so unreported activity is increasingly visible.
The 60-day property CGT return
The 60-day Capital Gains Tax return on residential property is the deadline landlords most often miss, because it falls outside the Self Assessment cycle and runs from completion, not exchange. Private residence relief for periods you lived in the property, plus the final nine months, reduces the gain. Penalties for a late return mirror Self Assessment, starting at £100.
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.
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.
Questions
Crypto Tax questions from Marylebone
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.
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.
Do you have an office in Marylebone?
No. IGI Accounting is an online-only firm. We serve Marylebone, Westminster and every other UK postcode remotely, with records sent by WhatsApp or email and everything filed electronically. The absence of local premises is why the fee for crypto tax is the same in Marylebone as anywhere else in the country, and why there is nothing to visit and nothing to print.
Is crypto tax in Marylebone really the same price as elsewhere?
Yes. The fee published on this page is what a client in Marylebone, Westminster pays and what a client in any other part of England pays. It is confirmed in writing before work starts and the invoice matches the quote. Where a higher package applies because your situation is more complex, we say so at the quote stage, never afterwards.
